+In the following log, modification dates are listed using the European
+convention in which the day comes before the month (ie. DD/MM/YYYY).
+The most recent modifications are listed first.
+
+25/05/2002 mcs@astro.caltech.edu  (based on suggestions by Paul Smith)
+           pathutil.c
+             Apparently, under QNX pathconf("/",_PC_PATH_MAX) returns
+             EINVAL. At Paul's suggestion I have modified the code to
+             silently substitute the existing MAX_PATHLEN_FALLBACK
+             value if pathconf() returns an error of any kind.
+           homedir.c
+             Under QNX, sysconf(_SC_GETPW_R_SIZE_MAX) also apparently
+             returns EINVAL, so as with pathconf() I modified the code
+             to substitute a fallback default, rather than
+             complaining and failing.
+           enhance.c
+             Paul told me that the inclusion of sys/termios.h was
+             causing compilation of enhance.c to fail under QNX. This
+             line is a bug.  The correct thing to do is include
+             termios.h without a sub-directory prefix, as I was
+             already doing futher up in the file, so I have just
+             removed the errant include line.
+
+12/02/2002 mcs@astro.caltech.edu
+           getline.c configure.in configure
+             Mac OS X doesn't have a term.h or termcap.h, but it does
+             define prototypes for tputs() and setupterm(), so the
+             default prototypes that I was including if no headers
+             where available, upset it. I've removed these prototypes.
+             I also now conditionally include whichever is found of
+             curses.h and ncurses/curses.h for both termcap and
+             terminfo (before I wasn't including curses.h when
+             termcap was selected).
+
+12/02/2002 mcs@astro.caltech.edu
+           Updated version number to 1.4.1, ready for a micro
+           release.
+
+12/02/2002 mcs@astro.caltech.edu
+           html/index.html
+             Added Mac OS X and Cygwin to the list of systems that
+             can compile libtecla.
+
+12/02/2002 mcs@astro.caltech.edu
+           getline.c
+             Under Mac OS X, the tputs() callback function returns
+             void, instead of the int return value used by other
+             systems. This declaration is now used if both __MACH__
+             and __APPLE__ are defined. Hopefully these are the
+             correct system macros to check. Thanks for Stephan
+             Fiedler for providing information on Mac OS X.
+
+11/02/2002 mcs@astro.caltech.edu
+           configure.in configure getline.c
+             Some systems don't have term.h, and others have it hidden
+             in an ncurses sub-directory of the standard system include
+             directory. If term.h can't be found, simply don't include
+             it. If it is in an ncurses sub-directory, include
+             ncurses/term.h instead of term.h.
+
+04/02/2002 mcs@astro.caltech.edu
+           configure.in configure Makefile.in Makefile.rules
+             Use ranlib on systems that need it (Mac OS X).  Also,
+             make all components of the installation directories where
+             needed, instead of assuming that they exist.
+
+04/02/2002 mcs@astro.caltech.edu
+           getline.c
+             When the tab completion binding was unbound from the tab
+             key, hitting the tab key caused gl_get_line() to ring the
+             bell instead of inserting a tab character. This is
+             problematic when using the 'enhance' program with
+             Jython, since tabs are important in Python. I have
+             corrected this.
+
+10/12/2001 Version 1.4.0 released.
+
+10/12/2001 mcs@astro.caltech.edu
+           getline.c
+             If the TIOCGWINSZ ioctl doesn't work, as is the case when
+             running in an emacs shell, leave the size unchanged, rather
+             than returning a fatal error.
+
+07/12/2001 mcs@astro.caltech.edu
+           configure.in configure
+             Now that the configure version of CFLAGS is included in
+             the makefile, I noticed that the optimization flags -g
+             and -O2 had been added. It turns out that if CFLAGS isn't
+             already set, the autoconf AC_PROG_CC macro initializes it
+             with these two optimization flags. Since this would break
+             backwards compatibility in embedded distributions that
+             already use the OPT= makefile argument, and because
+             turning debugging on needlessly bloats the library, I now
+             make sure that CFLAGS is set before calling this macro.
+
+07/12/2001 mcs@astro.caltech.edu
+           enhance.c
+             Use argv[0] in error reports instead of using a
+             hardcoded macro.
+
+07/12/2001 mcs@astro.caltech.edu
+           getline.c
+             The cut buffer wasn't being cleared after being
+             used as a work buffer by gl_load_history().
+
+06/12/2001 mcs@astro.caltech.edu
+           configure.in configure
+             I removed my now redundant definition of SUN_TPUTS from
+             CFLAGS. I also added "-I/usr/include" to CFLAGS under
+             Solaris to prevent gcc from seeing conflicting versions
+             of system header files in /usr/local/include.
+
+06/12/2001 Markus Gyger (logged here by mcs)
+           Lots of files.
+             Lots of corrections to misspellings and typos in the
+             comments.
+           getline.c
+             Markus reverted a supposed fix that I added a day or two
+             ago. I had incorrectly thought that in Solaris 8, Sun had
+             finally brought their declaration of the callback
+             function of tputs() into line with other systems, but it
+             turned out that gcc was pulling in a GNU version of
+             term.h from /usr/local/include, and this was what
+             confused me.
+
+05/12/2001 mcs@astro.caltech.edu
+           Makefile.in
+             I added @CFLAGS@ to the CFLAGS assignment, so that
+             if CFLAGS is set as an environment variable when
+             configure is run, the corresponding make variable
+             includes its values in the output makefile.
+
+05/12/2001 mcs@astro.caltech.edu
+           getline.c libtecla.h libtecla.map man3/gl_get_line.3
+           man3/gl_last_signal.3
+             I added a function that programs can use to find out
+             which signal caused gl_get_line() to return EINTR.
+
+05/12/2001 mcs@astro.caltech.edu
+           getline.c
+             When the newline action was triggered by a printable
+             character, it failed to display that character. It now
+             does. Also, extra control codes that I had added, to
+             clear to the end of the display after the carriage return,
+             but before displaying the prompt, were confusing expect
+             scripts, so I have removed them. This step is now done
+             instead in gl_redisplay() after displaying the full input
+             line.
+
+05/12/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             A user convinced me that continuing to invoke meta
+             keybindings for meta characters that are printable is a
+             bad idea, as is allowing users to ask to have setlocale()
+             called behind the application's back. I have thus changed
+             this. The setlocale configuration option has gone, and
+             gl_get_line() is now completely 8-bit clean, by default.
+             This means that if a meta character is printable, it is
+             treated as a literal character, rather than a potential
+             M-c binding.  Meta bindings can still be invoked via
+             their Esc-c equivalents, and indeed most terminal
+             emulators either output such escape pairs by default when
+             the meta character is pressed, or can be configured to do
+             so. I have documented how to configure xterm to do this,
+             in the man page.
+
+03/12/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             gl_get_line() by default now prints any 8-bit printable
+             characters that don't match keybindings. Previously
+             characters > 127 were only printed if preceded by the
+             literal-next action.  Alternatively, by placing the
+             command literal_if_printable in the tecla configuration
+             file, all printable characters are treated as literal
+             characters, even if they are bound to action functions.
+
+             For international users of programs written by
+             programmers that weren't aware of the need to call
+             setlocale() to support alternate character sets, the
+             configuration file can now also contain the single-word
+             command "setlocale", which tells gl_get_line() to remedy
+             this.
+
+27/11/2001 mcs@astro.caltech.edu
+           demo.c demo2.c enhance man3/gl_get_line.3
+             All demos and programs now call setlocale(LC_CTYPE,"").
+             This makes them support character sets of different
+             locales, where specified with the LC_CTYPE, LC_ALL, or
+             LANG environment variables. I also added this to the demo
+             in the man page, and documented its effect.
+
+27/11/2001 mcs@astro.caltech.edu
+           getline.c
+             When displaying unsigned characters with values over
+             127 literally, previously it was assumed that they would
+             all be displayable. Now isprint() is consulted, and if it
+             says that a character isn't printable, the character code
+             is displayed in octal like \307. In non-C locales, some
+             characters with values > 127 are displayable, and
+             isprint() tells gl_get_line() which are and which aren't.
+
+27/11/2001 mcs@astro.caltech.edu
+           getline.c pathutil.c history.c enhance.c demo2.c
+             All arguments of the ctype.h character class functions
+             are now cast to (int)(unsigned char). Previously they
+             were cast to (int), which doesn't correctly conform to
+             the requirements of the C standard, and could cause
+             problems for characters with values > 127 on systems
+             with signed char's.

+             Signal handling has now been modified to be customizable.
+             Signals that are trapped by default can be removed from
+             the list of trapped signals, and signals that aren't
+             currently trapped, can be added to the list. Applications
+             can also specify the signal and terminal environments in

+             what gl_get_line() does after the signal handler returns.

+             Removed ^O from the default VT100 sgr0 capability
+             string.  Apparently it can cause problems with some

+             Although the default remains to display the prompt string

+             directives.
+

+           enhance.c Makefile.rules configure.in configure
+             I added a new program to the distribution that allows one

+             providing command-line editing.

+           libtecla.h getline.c man3/gl_get_line.3 history.c history.h
+             I added a max_lines argument to gl_show_history() and
+             _glh_show_history(). This can optionally be used to
+             set a limit on the number of history lines displayed.
+           libtecla.h getline.c man3/gl_get_line.3
+             I added a new function called gl_replace_prompt(). This

+           getline.c man3/gl_get_line.3 man3/gl_echo_mode.3

+             For those cases where a terminal provides its own
+             high-level terminal editing facilities, you can now
+             specify an edit-mode argument of 'none'. This disables
+             all tecla key bindings, and by using canonical terminal
+             input mode instead of raw input mode, editing is left up
+             to the terminal driver.

+           man3/gl_get_line.3 man3/gl_history_info.3
+             I added the new gl_state_of_history(),

+             functions for querying information about the

+           history.c
+             While testing the new gl_size_of_history()
+             function, I noticed that when the history buffer
+             wrapped, any location nodes of old lines between
+             the most recent line and the end of the buffer
+             weren't being removed. This could result in bogus
+             entries appearing at the start of the history list.

+           libtecla.h getline.c history.c history.h man3/gl_get_line.3
+             gl_show_history() now takes a format string argument

+             information. It also now provides the option of either
+             displaying all history lines or just those of the
+             current history group.
+           getline.c man3/gl_get_line.3
+             gl_get_line() only archives lines in the history buffer

+             A user noted that on systems where the configure script
+             couldn't be used, it was inconvenient to have the version
+             number macros set by the configure script, so they are
+             now specified in libtecla.h. To reduce the likelihood
+             that the various files where the version number now
+             appears might get out of sync, I have written the
+             update_version script, which changes the version number
+             in all of these files to a given value.

+             I implemented history streams. History streams
+             effectively allow multiple history lists to be stored in
+             a single history buffer. Lines in the buffer are tagged
+             with the current stream identification number, and
+             lookups only consider lines that are marked with the

+
+           getline.c
+             Previously new_GetLine() installed a persistent signal
+             handler to be sure to catch the SIGWINCH (terminal size
+             change) signal between calls to gl_get_line(). This had
+             the drawback that if multiple GetLine objects were
+             created, only the first GetLine object used after the
+             signal was received, would see the signal and adapt to
+             the new terminal size. Instead of this, a signal handler
+             for sigwinch is only installed while gl_get_line() is
+             running, and just after installing this handler,
+             gl_get_line() checks for terminal size changes that
+             might have occurred while the signal handler wasn't
+             installed.
+           getline.c
+             Dynamically allocated copies of capability strings looked
+             up in the terminfo or termcap databases are now made, so
+             that calls to setupterm() etc for one GetLine object
+             don't get trashed when another GetLine object calls
+             setupterm() etc. It is now safe to allocate and use
+             multiple GetLine objects, albeit only within a single
+             thread.

+             Automatic reading of ~/.teclarc is now postponed until
+             the first call to gl_get_line(), to give the application
+             the chance to specify alternative configuration sources
+             with the new function gl_configure_getline(). The latter
+             function allows configuration to be done with a string, a
+             specified application-specific file, and/or a specified
+             user-specific file. I also added a read-init-files action
+             function, for re-reading the configuration files, if any.
+             This is by default bound to ^X^R. This is all documented

+
+           getline.c man3/gl_get_line.3
+             A customized completion function can now arrange for

+             setting the last character of the optional continuation

+             terminfo (eg. NetBSD). I traced the bug back to a lack of
+             sufficient quoting of multi-line m4 macro arguments in

+             configure script.

+
+           getline.c
+             getline.c wouldn't compile when termcap was selected as

+             passed a non-existent variable, in place of the term[]
+             argument of gl_control_strings(). Also if
+             gl_change_terminal() is called with term==NULL, "ansi"
+             is now substituted.

+           getline.c
+             gl_change_terminal() was being called by gl_change_editor(),

+             stored as those to be restored later, if called by an
+             action function. gl_change_terminal() was being called in
+             this case to re-establish terminal-specific key bindings,
+             so I have just split this part of the function out into
+             a separate function for both gl_change_editor() and
+             gl_change_terminal() to call.
+
+12/06/2001 mcs@astro.caltech.edu
+
+           getline.c
+             Signal handling has been improved. Many more signals are
+             now trapped, and instead of using a simple flag set by a
+             signal handler, race conditions are avoided by blocking
+             signals during most of the gl_get_line() code, and
+             unblocking them via calls to sigsetjmp(), just before
+             attempting to read each new character from the user.
+             The matching use of siglongjmp() in the signal
+             handlers ensures that signals are reblocked correctly
+             before they are handled. In most cases, signals cause
+             gl_get_line() to restore the terminal modes and signal
+             handlers of the calling application, then resend the
+             signal to the application. In the case of SIGINT, SIGHUP,
+             SIGPIPE, and SIGQUIT, if the process still exists after
+             the signals are resent, gl_get_line() immediately returns
+             with appropriate values assigned to errno. If SIGTSTP,
+             SIGTTIN or SIGTTOU signals are received, the process is
+             suspended. If any other signal is received, and the
+             process continues to exist after the signal is resent to
+             the calling application, line input is resumed after the
+             terminal is put back into raw mode, the gl_get_line()
+             signal handling is restored, and the input line redrawn.
+           man/gl_get_line(3)
+             I added a SIGNAL HANDLING section to the gl_get_line()
+             man page, describing the new signal handling features.

+             provided by Tim Eliseo, plus the ring-bell action and
+             the new "nobeep" configuration option.
+           getline.c
+             I modified gl_change_editor() to remove and reinstate the
+             terminal settings as well as the default bindings, since
+             these have editor-specific differences. I also modified
+             it to not abort if a key-sequence can't be bound for some
+             reason. This allows the new vi-mode and emacs-mode
+             bindings to be used safely.
+           getline.c
+             When the line was re-displayed on receipt of a SIGWINCH
+             signal, the result wasn't visible until the next
+             character was typed, since a call to fflush() was needed.
+             gl_redisplay_line() now calls gl_flush_output() to remedy
+             this.
+
+17/05/2001 mcs@astro.catlech.edu
+
+           getline.c
+             Under Linux, calling fflush(gl->output_fd) hangs if
+             terminal output has been suspended with ^S. With the
+             tecla library taking responsability for reading the stop
+             and start characters this was a problem, because once
+             hung in fflush(), the keyboard input loop wasn't entered,
+             so the user couldn't type the start character to resume
+             output.  To remedy this, I now have the terminal process
+             these characters, rather than the library.
+
+12/05/2001 mcs@astro.caltech.edu
+
+           getline.c
+             The literal-next action is now implemented as a single
+             function which reads the next character itself.
+             Previously it just set a flag which effected the
+             interpretation of the next character read by the input
+             loop.
+           getline.c
+             Added a ring-bell action function. This is currently
+             unbound to any key by default, but it is used internally,
+             and can be used by users that want to disable any of the
+             default key-bindings.
+
+12/05/2001 Tim Eliseo    (logged here by mcs)
+
+           getline.c
+             Don't reset gl->number until after calling an action
+             function. By looking at whether gl->number is <0 or
+             not, action functions can then tell whether the count
+             that they were passed was explicitly specified by the
+             user, as opposed to being defaulted to 1.
+           getline.c
+             In vi, the position at which input mode is entered
+             acts as a barrier to backward motion for the few
+             backward moving actions that are enabled in input mode.
+             Tim added this barrier to getline.
+           getline.c
+             In gl_get_line() after reading an input line, or
+             having the read aborted by a signal, the sig_atomic_t
+             gl_pending_signal was being compared to zero instead
+             of -1 to see if no signals had been received.
+             gl_get_line() will thus have been calling raise(-1),
+             which luckily didn't seem to do anything. Tim also
+             arranged for errno to be set to EINTR when a signal
+             aborts gl_get_line().
+           getline.c
+             The test in gl_add_char_to_line() for detecting
+             when overwriting a character with a wider character,
+             had a < where it needed a >. Overwriting with a wider
+             character thus overwrote trailing characters. Tim also
+             removed a redundant copy of the character into the
+             line buffer.
+           getline.c
+             gl_cursor_left() and gl->cursor_right() were executing
+             a lot of redundant code, when the existing call to the
+             recently added gl_place_cursor() function, does all that
+             is necessary.
+           getline.c
+             Remove redundant code from backward_kill_line() by
+             re-implimenting in terms of gl_place_cursor() and
+             gl_delete_chars().
+           getline.c
+             gl_forward_delete_char() now records characters in cut
+             buffer when in vi command mode.
+           getline.c
+             In vi mode gl_backward_delete_char() now only deletes
+             up to the point at which input mode was entered. Also
+             gl_delete_chars() restores from the undo buffer when
+             deleting in vi insert mode.
+           getline.c
+             Added action functions, vi-delete-goto-column,
+             vi-change-to-bol, vi-change-line, emacs-mode, vi-mode,
+             vi-forward-change-find, vi-backward-change-find,

+
+           configure.in
+             Old versions of GNU ld don't accept version scripts.
+             Under Linux I thus added a test to try out ld with
+             the --version-script argument to see if it works.
+             If not, version scripts aren't used.
+           configure.in
+             My test for versions of Solaris earlier than 7
+             failed when confronted by a three figure version

+
+           getline.c
+             In vi mode, history-search-backward and
+             history-search-forward weren't doing anything when
+             invoked at the start of an empty line, whereas
+             they should have acted like up-history and down-history.
+           Makefile.in Makefile.rules
+             When shared libraries are being created, the build
+             procedure now arranges for any alternate library
+             links to be created as well, before linking the
+             demos. Without this the demos always linked to the
+             static libraries (which was perfectly ok, but wasn't a
+             good example).
+           Makefile.in Makefile.rules
+             On systems on which shared libraries were being created,
+             if there were no alternate list of names, make would
+             abort due to a Bourne shell 'for' statement that didn't
+             have any arguments. Currently there are no systems who's
+             shared library configurations would trigger this
+             problem.
+           Makefile.rules
+             The demos now relink to take account of changes to the
+             library.
+           configure.in configure
+             When determining whether the reentrant version of the
+             library should be compiled by default, the configure
+             script now attempts to compile a dummy program that
+             includes all of the appropriate system headers and
+             defines _POSIX_C_SOURCE. This should now be a robust test
+             on systems which use C macros to alias these function
+             names to other internal functions.
+           configure.in
+             Under Solaris 2.6 and earlier, the curses library is in
+             /usr/ccs/lib. Gcc wasn't finding this. In addition to
+             remedying this, I had to remove "-z text" from
+             LINK_SHARED under Solaris to get it to successfully
+             compile the shared library against the static curses
+             library.
+           configure.in
+             Under Linux the -soname directive was being used
+             incorrectly, citing the fully qualified name of the
+             library instead of its major version alias. This will
+             unfortunately mean that binaries linked with the 1.2.3
+             and 1.2.4 versions of the shared library won't use
+             later versions of the library unless relinked.

+
+28/04/2001 mcs@astro.caltech.edu
+
+           configure.in
+             I removed the --no-undefined directive from the Linux
+             LINK_SHARED command. After recent patches to our RedHat
+             7.0 systems ld started reporting some internal symbols of
+             libc as being undefined.  Using nm on libc indicated that
+             the offending symbols are indeed defined, albeit as
+             "common" symbols, so there appears to be a bug in
+             RedHat's ld. Removing this flag allows the tecla shared
+             library to compile, and programs appear to function fine.
+           man3/gl_get_line.3
+             The default key-sequence used to invoke the
+             read-from-file action was incorrectly cited as ^Xi
+             instead of ^X^F.
+
+26/04/2001 mcs@astro.caltech.edu
+
+           getline.c man3/gl_get_line.3
+             A new vi-style editing mode was added. This involved
+             adding many new action functions, adding support for
+             specifying editing modes in users' ~/.teclarc files,
+             writing a higher level cursor motion function to support
+             the different line-end bounds required in vi command
+             mode, and a few small changes to support the fact that vi
+             has two modes, input mode and command mode with different
+             bindings.
+
+             When vi editing mode is enabled, any binding that starts
+             with an escape or a meta character, is interpreted as a
+             command-mode binding, and switches the library to vi
+             command mode if not already in that mode. Once in command
+             mode the first character of all keysequences entered
+             until input mode is re-enabled, are quietly coerced to
+             meta characters before being looked up in the key-binding
+             table. So, for example, in the key-binding table, the
+             standard vi command-mode 'w' key, which moves the cursor
+             one word to the right, is represented by M-w. This
+             emulates vi's dual sets of bindings in a natural way
+             without needing large changes to the library, or new
+             binding syntaxes. Since cursor keys normally emit
+             keysequences which start with escape, it also does
+             something sensible when a cursor key is pressed during
+             input mode (unlike true vi, which gets upset).
+
+             I also added a ^Xg binding for the new list-glob action
+             to both the emacs and vi key-binding tables. This lists
+             the files that match the wild-card expression that
+             precedes it on the command line.
+
+             The function that reads in ~/.teclarc used to tell
+             new_GetLine() to abort if it encountered anything that it
+             didn't understand in this file. It now just reports an
+             error and continues onto the next line.
+           Makefile.in:
+             When passing LIBS=$(LIBS) to recursive invokations of
+             make, quotes weren't included around the $(LIBS) part.
+             This would cause problems if LIBS ever contained more
+             than one word (with the supplied configure script this
+             doesn't happen currently). I added these quotes.
+           expand.c man3/ef_expand_file.3:
+             I wrote a new public function called ef_list_expansions(),
+             to list the matching filenames returned by
+             ef_expand_file().
+
+             I also fixed the example in the man page, which cited
+             exp->file instead of exp->files, and changed the
+             dangerous name 'exp' with 'expn'.
+           keytab.c:
+             Key-binding tables start with 100 elements, and are
+             supposedly incremented in size by 100 elements whenever
+             the a table runs out of space. The realloc arguments to
+             do this were wrong. This would have caused problems if
+             anybody added a lot of personal bindings in their
+             ~/.teclarc file. I only noticed it because the number of
+             key bindings needed by the new vi mode exceeded this
+             number.
+           libtecla.map
+             ef_expand_file() is now reported as having been added in
+             the upcoming 1.3.0 release.

+             relative instead of absolute.
+           Makefile.rules:
+             The HP-UX libtecla.map.opt file should be made in the

+           cplmatch.c demo2.c history.c pcache.c
+             To allow the library to be compiled with a C++ compiler,
+             without generating warnings, a few casts were added where
+             void* return values were being assigned directly to
+             none void* pointer variables.
+
+25/03/2001 mcs@astro.caltech.edu
+
+           libtecla.map:
+             Added comment header to explain the purpose of the file.
+             Also added cpl_init_FileArgs to the list of exported
+             symbols. This symbol is deprecated, and no longer
+             documented, but for backwards compatibility, it should
+             still be exported.
+           configure:
+             I had forgotten to run autoconf before releasing version
+             1.2.4, so I have just belatedly done so.  This enables

+             A couple of the function prototypes in libtecla.h have

+           getline.c
+             The fix for the end-of-line problem that I released a
+             couple of weeks ago, only worked for the first line,
+             because I was handling this case when the cursor position
+             was equal to the last column, rather than when the cursor
+             position modulo ncolumn was zero.
+           Makefile.in Makefile.rules
+             The demos are now made by default, their rules now being

+           INSTALL
+             I documented how to compile the library in a different
+             directory than the distribution directory.
+             I also documented features designed to facilitate
+             configuring and building the library as part of another
+             package.
+
+17/03/2001 Markus Gyger (logged here by mcs)
+
+           getline.c
+             Until now cursor motions were done one at a time. Markus
+             has added code to make use the of the terminfo capability
+             that moves the cursor by more than one position at a
+             time. This greatly improves performance when editing near
+             the start of long lines.
+           getline.c
+             To further improve performance, Markus switched from
+             writing one character at a time to the terminal, using
+             the write() system call, to using C buffered output
+             streams. The output buffer is only flushed when
+             necessary.
+           Makefile.rules Makefile.in configure.in
+             Added support for compiling for different architectures
+             in different directories. Simply create another directory
+             and run the configure script located in the original
+             directory.
+           Makefile.in configure.in libtecla.map
+             Under Solaris, Linux and HP-UX, symbols that are to be
+             exported by tecla shared libraries are explicitly specified
+             via symbol map files. Only publicly documented functions
+             are thus visible to applications.
+           configure.in
+             When linking shared libraries under Solaris SPARC,
+             registers that are reserved for applications are marked
+             as off limits to the library, using -xregs=no%appl when
+             compiling with Sun cc, or -mno-app-regs when compiling
+             with gcc. Also removed -z redlocsym for Solaris, which
+             caused problems under some releases of ld.
+           homedir.c  (after minor changes by mcs)
+             Under ksh, ~+ expands to the current value of the ksh
+             PWD environment variable, which contains the path of
+             the current working directory, including any symbolic
+             links that were traversed to get there. The special
+             username "+" is now treated equally by tecla, except
+             that it substitutes the return value of getcwd() if PWD
+             either isn't set, or if it points at a different
+             directory than that reported by getcwd().

+08/03/2001 mcs@astro.caltech.edu
+
+           getline.c
+             On compiling the library under HP-UX for the first time
+             I encountered and fixed a couple of bugs:
+
+             1. On all systems except Solaris, the callback function
+                required by tputs() takes an int argument for the
+                character that is to be printed. Under Solaris it
+                takes a char argument. The callback function was
+                passing this argument, regardless of type, to write(),
+                which wrote the first byte of the argument.  This was
+                fine under Solaris and under little-endian systems,
+                because the first byte contained the character to be
+                written, but on big-endian systems, it always wrote
+                the zero byte at the other end of the word. As a
+                result, no control characters were being written to
+                the terminal.
+             2. While attempting to start a newline after the user hit
+                enter, the library was outputting the control sequence
+                for moving the cursor down, instead of the newline
+                character. On many systems the control sequence for
+                moving the cursor down happends to be a newline
+                character, but under HP-UX it isn't. The result was
+                that no new line was being started under HP-UX.

+             script. In addition to relieving the user of the need to

+             of the reentrant version of the library on platforms that
+             can handle it, along with the creation of shared
+             libraries where configured. On systems that aren't known
+             to the configure script, just the static tecla library is
+             compiled. This is currently the case on all systems
+             except Linux, Solaris and HP-UX. In the hope that
+             installers will provide specific conigurations for other
+             systems, the configure.in script is heavily commented,

+           getline.c
+             It turns out that most terminals, but not all, on writing
+             a character in the rightmost column, don't wrap the
+             cursor onto the next line until the next character is
+             output. This library wasn't aware of this and thus if one
+             tried to reposition the cursor from the last column,
+             gl_get_line() thought that it was moving relative to a
+             point on the next line, and thus moved the cursor up a
+             line. The fix was to write one extra character when in
+             the last column to force the cursor onto the next line,
+             then backup the cursor to the start of the new line.
+           getline.c
+             On terminal initialization, the dynamic LINES and COLUMNS
+             environment variables were ignored unless
+             terminfo/termcap didn't return sensible dimensions. In
+             practice, when present they should override the static
+             versions in the terminfo/termcap databases. This is the
+             new behavior. In reality this probably won't have caused
+             many problems, because a SIGWINCH signal which informs of
+             terminal size changes is sent when the terminal is
+             opened, so the dimensions established during
+             initialization quickly get updated on most systems.

+             Three months ago I moved the point at which termios.h
+             was included in getline.c. Unfortunately, I didn't notice
+             that this moved it to after the test for TIOCGWINSZ being
+             defined. This resulted in SIGWINCH signals not being
+             trapped for, and thus terminal size changes went
+             unnoticed. I have now moved the test to after the 
+             inclusion of termios.h.

+             wasn't on the last of the wrapped lines, the text of the

+             line written by the application, or the next input
+             line. Somehow this slipped through the cracks and wasn't

+           pcache.c libtecla.h
+             With all filesystems local, demo2 was very fast to start
+             up, but on a Sun system with one of the target
+             directories being on a remote nfs mounted filesystem, the
+             startup time was many seconds. This was due to the
+             executable selection callback being applied to all files
+             in the path at startup. To avoid this, all files are now
+             included in the cache, and the application specified
+             file-selection callback is only called on files as they
+             are matched. Whether the callback rejected or accepted
+             them is then cached so that the next time an already
+             checked file is looked at, the callback doesn't have to
+             be called. As a result, startup is now fast on all
+             systems, and since usually there are only a few matching
+             file completions at a time, the delay during completion
+             is also usually small. The only exception is if the user
+             tries to complete an empty string, at which point all
+             files have to be checked. Having done this once, however,
+             doing it again is fast.
+           man3/pca_lookup_file.3
+             I added a man page documenting the new PathCache module.
+           man3/<many-new-files>.3
+             I have added man pages for all of the functions in each
+             of the modules. These 1-line pages use the .so directive
+             to redirect nroff to the man page of the parent module.
+           man Makefile update_html
+             I renamed man to man3 to make it easier to test man page
+             rediction, and updated Makefile and update_html
+             accordingly. I also instructed update_html to ignore
+             1-line man pages when making html equivalents of the man
+             pages.
+           cplmatch.c
+             In cpl_list_completions() the size_t return value of
+             strlen() was being used as the length argument of a "%*s"
+             printf directive. This ought to be an int, so the return
+             value of strlen() is now cast to int. This would have
+             caused problems on architectures where the size of a
+             size_t is not equal to the size of an int.

+02/02/2001 mcs@astro.caltech.edu
+
+           getline.c
+             Under UNIX, certain terminal bindings are set using the
+             stty command. This, for example, specifies which control
+             key generates a user-interrupt (usually ^C or ^Y). What I
+             hadn't realized was that ASCII NUL is used as the way to
+             specify that one of these bindings is unset. I have now
+             modified the code to skip unset bindings, leaving the
+             corresponding action bound to the built-in default, or a
+             user provided binding.
+
+28/01/2001 mcs@astro.caltech.edu
+
+           pcache.c libtecla.h
+             A new module was added which supports searching for files
+             in any colon separated list of directories, such as the
+             unix execution PATH environment variable. Files in these
+             directories, after being individually okayed for
+             inclusion via an application provided callback, are
+             cached in a PathCache object. You can then look up the
+             full pathname of a given filename, or you can use the
+             provided completion callback to list possible completions
+             in the path-list. The contents of relative directories,
+             such as ".", obviously can't be cached, so these
+             directories are read on the fly during lookups and
+             completions. The obvious application of this facility is
+             to provide Tab-completion of commands, and thus a
+             callback to place executable files in the cache, is
+             provided.
+           demo2.c
+             This new program demonstrates the new PathCache
+             module. It reads and processes lines of input until the
+             word 'exit' is entered, or C-d is pressed. The default
+             tab-completion callback is replaced with one which at the
+             start of a line, looks up completions of commands in the
+             user's execution path, and when invoked in other parts of
+             the line, reverts to normal filename completion. Whenever
+             a new line is entered, it extracts the first word on the
+             line, looks it up in the user's execution path to see if
+             it corresponds to a known command file, and if so,
+             displays the full pathname of the file, along with the
+             remaining arguments.
+           cplfile.c
+             I added an optional pair of callback function/data
+             members to the new cpl_file_completions() configuration
+             structure. Where provided, this callback is asked
+             on a file-by-file basis, which files should be included
+             in the list of file completions. For example, a callback
+             is provided for listing only completions of executable
+             files.
+           cplmatch.c
+             When listing completions, the length of the type suffix
+             of each completion wasn't being taken into account
+             correctly when computing the column widths. Thus the
+             listing appeared ragged sometimes. This is now fixed.
+           pathutil.c
+             I added a function for prepending a string to a path,
+             and another for testing whether a pathname referred to
+             an executable file.

+           libtecla.h cplmatch.c man/cpl_complete_word.3
+             The use of a publically defined structure to configure
+             the cpl_file_completions() callback was flawed, so a new
+             approach has been designed, and the old method, albeit
+             still supported, is no longer documented in the man
+             pages. The definition of the CplFileArgs structure in
+             libtecla.h is now accompanied by comments warning people
+             not to modify it, since modifications could break
+             applications linked to shared versions of the tecla
+             library. The new method involves an opaque CplFileConf
+             object, instances of which are returned by a provided
+             constructor function, configured with provided accessor
+             functions, and when no longer needed, deleted with a
+             provided destructor function. This is documented in the
+             cpl_complete_word man page. The cpl_file_completions()
+             callback distinguishes what type of configuration
+             structure it has been sent by virtue of a code placed at
+             the beginning of the CplFileConf argument by its
+             constructor.

+             I added upper-case bindings for the default meta-letter
+             keysequences such as M-b. They thus continue to work
+             when the user has caps-lock on.
+           Makefile
+             I re-implemented the "install" target in terms of new
+             install_lib, install_inc and install_man targets. When
+             distributing the library with other packages, these new
+             targets allows for finer grained control of the

+
+           getline.c man/gl_get_line.3
+             I realized that the recall-history action that I
+             implemented wasn't what Markus had asked me for. What he
+             actually wanted was for down-history to continue going
+             forwards through a previous history recall session if no
+             history recall session had been started while entering
+             the current line. I have thus removed the recall-history
+             action and modified the down-history action function
+             accordingly.
+
+24/12/2000 mcs@astro.caltech.edu
+
+           getline.c
+             I modified gl_get_line() to allow the previously returned

+           getline.c man/gl_get_line.3
+             I added a recall-history action function, bound to M^P.

+             of whether it was from the current or previous line.

+
+           getline.c history.h history.c man/gl_get_line.3
+             I implemented the equivalent of the ksh Operate action. I
+             have named the tecla equivalent "repeat-history". This
+             causes the line that is to be edited to returned, and
+             arranges for the next most recent history line to be
+             preloaded on the next call to gl_get_line(). Repeated
+             invocations of this action thus result in successive
+             history lines being repeated - hence the
+             name. Implementing the ksh Operate action was suggested
+             by Markus Gyger. In ksh it is bound to ^O, but since ^O
+             is traditionally bound by the default terminal settings,
+             to stop-output, I have bound the tecla equivalent to M-o.
+
+01/12/2000 mcs@astro.caltech.edu (Release of version 1.1h)
+
+           getline.c keytab.c keytab.h man/gl_get_line.3
+             I added a digit-argument action, to allow repeat
+             counts for actions to be entered. As in both tcsh
+             and readline, this is bound by default to each of
+             M-0, M-1 through to M-9, the number being appended
+             to the current repeat count. Once one of these has been
+             pressed, the subsequent digits of the repeat count can be
+             typed with or without the meta key pressed. It is also
+             possible to bind digit-argument to other keys, with or
+             without a numeric final keystroke. See man page for
+             details.
+
+           getline.c man/gl_get_line.3
+             Markus noted that my choice of M-< for the default
+             binding of read-from-file, could be confusing, since
+             readline binds this to beginning-of-history. I have
+             thus rebound it to ^X^F (ie. like find-file in emacs).
+
+           getline.c history.c history.h man/gl_get_line.3
+             I have now implemented equivalents of the readline
+             beginning-of-history and end-of-history actions.
+             These are bound to M-< and M-> respectively.
+
+           history.c history.h
+             I Moved the definition of the GlHistory type, and
+             its subordinate types from history.h to history.c.
+             There is no good reason for any other module to
+             have access to the innards of this structure.
+
+27/11/2000 mcs@astro.caltech.edu (Release of version 1.1g)
+
+           getline.c man/gl_get_line.3
+             I added a "read-from-file" action function and bound it
+             by default to M-<. This causes gl_get_line() to
+             temporarily return input from the file who's name
+             precedes the cursor.
+             
+26/11/2000 mcs@astro.caltech.edu
+
+           getline.c keytab.c keytab.h man/gl_get_line.3
+             I have reworked some of the keybinding code again.
+
+             Now, within key binding strings, in addition to the
+             previously existing notation, you can now use M-a to
+             denote meta-a, and C-a to denote control-a. For example,
+             a key binding which triggers when the user presses the
+             meta key, the control key and the letter [
+             simultaneously, can now be denoted by M-C-[, or M-^[ or
+             \EC-[ or \E^[.
+
+             I also updated the man page to use M- instead of \E in
+             the list of default bindings, since this looks cleaner.
+
+           getline.c man/gl_get_line.3
+             I added a copy-region-as-kill action function and
+             gave it a default binding to M-w.

+
+           *.c
+             Markus Gyger sent me a copy of a previous version of
+             the library, with const qualifiers added in appropriate
+             places. I have done the same for the latest version.
+             Among other things, this gets rid of the warnings
+             that are generated if one tells the compiler to
+             const qualify literal strings.
+
+           getline.c getline.h glconf.c
+             I have moved the contents of glconf.c and the declaration
+             of the GetLine structure into getline.c. This is cleaner,
+             since now only functions in getline.c can mess with the
+             innards of GetLine objects. It also clears up some problems
+             with system header inclusion order under Solaris, and also
+             the possibility that this might result in inconsistent
+             system macro definitions, which in turn could cause different
+             declarations of the structure to be seen in different files.
+
+           hash.c
+             I wrote a wrapper function to go around strcmp(), such that
+             when hash.c is compiled with a C++ compiler, the pointer
+             to the wrapper function is a C++ function pointer.
+             This makes it compatible with comparison function pointer
+             recorded in the hash table.

+           cplmatch.c getline.c libtecla.h
+             Markus noted that the Sun C++ compiler wasn't able to
+             match up the declaration of cpl_complete_word() in
+             libtecla.h, where it is surrounded by a extern "C" {}
+             wrapper, with the definition of this function in
+             cplmatch.c. My suspicion is that the compiler looks not
+             only at the function name, but also at the function
+             arguments to see if two functions match, and that the
+             match_fn() argument, being a fully blown function pointer
+             declaration, got interpetted as that of a C function in
+             one case, and a C++ function in the other, thus
+             preventing a match.
+
+             To fix this I now define a CplMatchFn typedef in libtecla.h,
+             and use this to declare the match_fn callback.
+
+20/11/2000 (Changes suggested by Markus Gyger to support C++ compilers):
+           expand.c
+             Renamed a variable called "explicit" to "xplicit", to
+             avoid conflicts when compiling with C++ compilers.
+           *.c
+             Added explicit casts when converting from (void *) to
+             other pointer types. This isn't needed in C but it is
+             in C++.
+           getline.c
+             tputs() has a strange declaration under Solaris. I was
+             enabling this declaration when the SPARC feature-test
+             macro was set. Markus changed the test to hinge on the
+             __sun and __SVR4 macros.
+           direader.c glconf.c stringrp.c
+             I had omitted to include string.h in these two files.
+
+           Markus also suggested some other changes, which are still
+           under discussion. With the just above changes however, the
+           library compiles without complaint using g++.
+

+           getline.h getline.c keytab.c keytab.h glconf.c
+           man/gl_get_line.3
+             I added support for backslash escapes (include \e
+             for the keyboard escape key) and literal binary
+             characters to the characters allowed within key sequences
+             of key bindings.
+
+           getline.h getline.c keytab.c keytab.h glconf.c
+           man/gl_get_line.3
+             I introduced symbolic names for the arrow keys, and
+             modified the library to use the cursor key sequences
+             reported by terminfo/termcap in addition to the default
+             ANSI ones. Anything bound to the symbolically named arrow
+             keys also gets bound to the default and terminfo/termcap
+             cursor key sequences. Note that under Solaris
+             terminfo/termcap report the properties of hardware X
+             terminals when TERM is xterm instead of the terminal
+             emulator properties, and the cursor keys on these two
+             systems generate different key sequences. This is an
+             example of why extra default sequences are needed.
+
+           getline.h getline.c keytab.c
+             For some reason I was using \e to represent the escape
+             character. This is supported by gcc, which thus doesn't
+             emit a warning except with the -pedantic flag, but isn't
+             part of standard C. I now use a macro to define escape
+             as \033 in getline.h, and this is now used wherever the
+             escape character is needed.
+
+17/11/2000 mcs@astro.caltech.edu (Release of version 1.1d)
+
+           getline.c, man/gl_get_line(3), html/gl_get_line.html
+             In tcsh ^D is bound to a function which does different
+             things depending on where the cursor is within the input
+             line. I have implemented its equivalent in the tecla
+             library. When invoked at the end of the line this action
+             function displays possible completions. When invoked on
+             an empty line it causes gl_get_line() to return NULL,
+             thus signalling end of input. When invoked within a line
+             it invokes forward-delete-char, as before. The new action
+             function is called del-char-or-list-or-eof.
+
+           getline.c, man/gl_get_line(3), html/gl_get_line.html
+             I found that the complete-word and expand-file actions
+             had underscores in their names instead of hyphens. This
+             made them different from all other action functions, so I
+             have changed the underscores to hyphens.
+
+           homedir.c
+             On SCO UnixWare while getpwuid_r() is available, the
+             associated _SC_GETPW_R_SIZE_MAX macro used by sysconf()
+             to find out how big to make the buffer to pass to this
+             function to cater for any password entry, doesn't
+             exist. I also hadn't catered for the case where sysconf()
+             reports that this limit is indeterminate. I have thus
+             change the code to substitute a default limit of 1024 if
+             either the above macro isn't defined or if sysconf() says
+             that the associated limit is indeterminate.

+17/11/2000 mcs@astro.caltech.edu (Release of version 1.1c)
+
+           getline.c, getline.h, history.c, history.h
+             I have modified the way that the history recall functions
+             operate, to make them better emulate the behavior of
+             tcsh. Previously the history search bindings always
+             searched for the prefix that preceded the cursor, then
+             left the cursor at the same point in the line, so that a
+             following search would search using the same prefix. This
+             isn't how tcsh operates. On finding a matching line, tcsh
+             puts the cursor at the end of the line, but arranges for
+             the followup search to continue with the same prefix,
+             unless the user does any cursor motion or character
+             insertion operations in between, in which case it changes
+             the search prefix to the new set of characters that are
+             before the cursor. There are other complications as well,
+             which I have attempted to emulate. As far as I can
+             tell, the tecla history recall facilities now fully
+             emulate those of tcsh.
+
+16/11/2000 mcs@astro.caltech.edu (Release of version 1.1b)

+           demo.c:
+             One can now quit from the demo by typing exit.
+
+           keytab.c:
+             The first entry of the table was getting deleted
+             by _kt_clear_bindings() regardless of the source
+             of the binding. This deleted the up-arrow binding.
+             Symptoms noted by gazelle@yin.interaccess.com.
+
+           getline.h:
+             Depending on which system include files were include
+             before the inclusion of getline.h, SIGWINCH and
+             TIOCGWINSZ might or might not be defined. This resulted
+             in different definitions of the GetLine object in
+             different files, and thus some very strange bugs! I have
+             now added #includes for the necessary system header files
+             in getline.h itself. The symptom was that on creating a
+             ~/.teclarc file, the demo program complained of a NULL
+             argument to kt_set_keybinding() for the first line of the
+             file.
+
+15/11/2000 mcs@astro.caltech.edu (Release of version 1.1a)
+
+           demo.c:
+             I had neglected to check the return value of
+             new_GetLine() in the demo program. Oops.
+
+           getline.c libtecla.h:
+             I wrote gl_change_terminal(). This allows one to change to
+             a different terminal or I/O stream, by specifying the
+             stdio streams to use for input and output, along with the
+             type of terminal that they are connected to.
+
+           getline.c libtecla.h:
+             Renamed GetLine::isterm to GetLine::is_term. Standard
+             C reserves names that start with "is" followed by
+             alphanumeric characters, so this avoids potential
+             clashes in the future.
+
+           keytab.c keytab.h
+             Each key-sequence can now have different binding
+             functions from different sources, with the user provided
+             binding having the highest precedence, followed by the
+             default binding, followed by any terminal specific
+             binding. This allows gl_change_terminal() to redefine the
+             terminal-specific bindings each time that
+             gl_change_terminal() is called, without overwriting the
+             user specified or default bindings. In the future, it will
+             also allow for reconfiguration of user specified
+             bindings after the call to new_GetLine(). Ie. deleting a
+             user specified binding should reinstate any default or
+             terminal specific binding.

+To compile and optionally install the library, it is first necessary
+to create a makefile for your system, by typing:
+
+  ./configure
+
+The Makefile that this generates is designed to install the files of
+the library in subdirectories of /usr/local/. If you would prefer to
+install them under a different directory, you can type:
+
+  ./configure --prefix /wherever
+
+Where you would replace /wherever with your chosen directory. Other
+command-line options are available, and can be listed by typing:
+
+  ./configure --help
+
+Having run the configure script, you are then ready to make the
+library. To do this, just type:
+
+  make
+
+What 'make' does depends on whether the configure script knows about
+your system. If the configure script doesn't know anything specific
+about your system, it will arrange for 'make' to produce the static
+tecla library, called libtecla.a, and if possible, the reentrant
+version of this called libtecla_r.a. If it does know about your
+system, it will also create shared libraries if possible. If you are
+on a system that isn't known, and you would like shared libraries to
+be compiled, please read the file called PORTING to see how this can
+be achieved.
+
+To install the library, its include file and it manual pages, type:
+
+  make install
+
+Note that this will also compile the library if you haven't already
+done so.
+
+Having compiled the library, if you wish, you can test it by running
+the demo programs. After building the library, you should find two
+programs, called demo and demo2, in the current directory.
+
+The first of the demos programs reads input lines from the user, and
+writes what was typed back to the screen. While typing a line of
+input, you can experiment with line editing, tab completion, history
+recall etc.. For details about these line editing features, see the
+man page gl_get_line(3). If you haven't installed this yet, you can
+see it anyway by typing:
+
+  nroff -man man3/gl_get_line.3 | more
+
+The second demo program, called demo2, demonstrates command-completion
+with the UNIX PATH. If you type in a partial command name, and press
+TAB, the command name will be completed if possible, and possible
+completions will be listed if it is ambiguous. When you then enter the
+line, the demo program then prints out the full pathname of the
+command that you typed. If you type anything after the command name,
+filename completion with the tab key reverts to its default behavior
+of completing filenames in the current directory.
+
+COMPILING IN A DIFFERENT DIRECTORY
+----------------------------------
+If you unpack the distribution in a directory which is visible from
+multiple hosts which have different architectures, you have the option
+of compiling the library for the different architectures in different
+directories. You might for example create a sub-directory for each
+architecture, under the top level directory of the distribution. You
+would then log in to a host of one of these architectures, cd to the
+sub-directory that you created for it, and type:
+
+  ../configure
+
+The configure script then creates a makefile in the current directory
+which is designed to build the library, object files, demos etc for
+the architecture of the current host, in the current directory, using
+the original source code in ../. You then repeat this procedure on
+hosts of other architectures.
+
+The compilation directories don't have to be sub-directories of the
+top level directory of the distribution. That was just described as an
+example. They can be anywhere you like.
+
+Every rule in the makefiles that are generated by the configure
+script, cites the paths of the target and source files explicitly, so
+this procedure should work on any system, without the need for vpath
+makefile support.
+
+EMBEDDING IN OTHER PACKAGE DISTRIBUTIONS
+----------------------------------------
+
+If you distribute the library with another package, which has its own
+heirarchy and configuration procedures, the following installation
+options may be of interest to you. At first glance, the use of a GNU
+configure script by the tecla library, may appear to reduce your
+options for controlling what gets made, and where it gets installed,
+but this isn't the case, because many of the parameters configured by
+the configure script are assigned to make variables which can be
+overriden when you run make.
+
+For example, lets say that you have your own configuration script in
+the parent directory of the libtecla top-level directory. In your
+configuration script, you would first need to have the following line:
+
+  (cd libtecla; ./configure)
+
+Now, from your makefile or whatever script you use to build your
+application, you would need to make the library. Assuming that your
+makefile or build script is in the parent directory of the libtecla
+distribution, the following line tells make to just make the
+non-reentrant, static version of the tecla library, and to install it
+and the tecla include file in sub-directories called lib and include
+in your current directory.
+
+  (cd libtecla; make LIBDIR=../lib INCDIR=../include TARGETS=normal TARGET_LIBS="static" install_lib install_inc)
+
+First, the LIBDIR=../lib means that on installing the library, it
+should be placed in the directory libtecla/../lib. Similarly INCDIR
+tells make where to place the include files. The install_lib and
+install_inc targets tell make to install the libraries and the include
+file. Because the install_man and install_bin targets have been
+omitted in this example, the man pages and programs aren't installed.
+If you were to include these additional targets then you could use the
+MANDIR and BINDIR variables, respectively to control where they were
+installed.
+
+The TARGETS variable is used to specify which of the normal and
+reentrant versions of the library are compiled. This can contain one
+or both of the words "normal" and "reentrant". If you don't specify
+this when you invoke make, the default value generated by the
+configure script will be used. Depending on whether reentrant POSIX
+functions are available for compilation of the reentrant version, this
+will be either "normal" or "normal reentrant".
+
+The TARGET_LIBS variable is used to specify which of the static and
+shared libraries are to be built. This can contain one or both of the
+words "static" and "shared". If you don't specify this when you invoke
+make, the default value generated by the configure script will be
+used. Depending on whether the configure script knows how to create
+shared libraries on the target system, this will be either "static" or
+"static shared". Beware that shared libraries aren't supported on many
+systems, so requiring "shared" will limit which systems you can
+compile your package on. Also note that unless your package installs
+the tecla library in a directory which all users of your program will
+have access to, you should only compile the static version.
+Instructions for adding shared-library creation rules for new systems
+are included in the PORTING file.
+
+The OPT variable can be used to change the default optimization from
+the default of "-O" to something else.
+
+The DEMOS variable controls whether the demo programs are built.
+Normally this has the value "demos", which tells the makefile to build
+the demo programs. Setting it to an empty string stops the demos from
+being built.
+
+The PROGRAMS variable is used to specify which programs are to be
+built and subsequently installed. All available programs are built by
+default. Currently there is only one such program, selected by
+specifying the word "enhance". This program uses tecla-enhanced
+pseudo-terminals to layer command line editing on top of third party
+programs.
+
+The PROGRAMS_R variable serves the same purpose as the PROGRAMS
+variable, except that programs listed here are linked with the
+reentrant version of the library, and should be specified with a _r
+suffix. Currently this variable is empty by default.

+The Tecla library was written with portability in mind, so no
+modifications to the source code should be needed on UNIX or LINUX
+platforms. The default compilation and linking arrangements should
+also work unchanged on these systems, but if no specific configuration
+has been provided for your system, shared libraries won't be compiled.
+Configuring these requires modifications to be made to the file:
+
+  configure.in
+
+This file is heavily commented (comments start with the word dnl) and
+is relatively simple, so the instructions and suggestions that you
+find in this file should be sufficient to help you figure out how to
+add a configuration for your system. This file is an input file to the
+GNU autoconf program, which uses it as a template for generating the
+distributed configure script. If autoconf is installed on your system,
+creating a new configure script is a simple matter of typing.
+
+  autoconf
+
+To avoid confusion with the leftovers of the previous configuration,
+you should then do the following:
+
+ rm -f config.cache
+ ./configure
+ make clean
+ ./configure
+ make
+
+The first ./configure creates a new makefile for your system, allowing
+you to type 'make clean' to discard any files that were compiled with
+the previous configuration. Since 'make clean' also deletes the new
+makefile, a second invokation of the configure script is then
+performed to re-create the makefile. The final make then creates the
+tecla library from scratch.
+
+Once you have confirmed that the new configuration works, please send
+the modified "configure.in" template to mcs@astro.caltech.edu, so that
+your changes can be included in subsequent releases.

+This is version 1.4.1 of the tecla command-line editing library.
+
+For the current official release, please direct your browser to:
+
+  http://www.astro.caltech.edu/~mcs/tecla/index.html
+
+The tecla library provides UNIX and LINUX programs with interactive
+command line editing facilities, similar to those of the unix tcsh
+shell. In addition to simple command-line editing, it supports recall
+of previously entered command lines, TAB completion of file names, and
+in-line wild-card expansion of filenames.  The internal functions
+which perform file-name completion and wild-card expansion are also
+available externally for optional use by programs, along with a module
+for tab-completion and lookup of filenames in a list of directories.
+
+Note that special care has been taken to allow the use of this library
+in threaded programs. The option to enable this is discussed in the
+Makefile, and specific discussions of thread safety are presented in
+the included man pages.
+
+For instructions on how to compile and install the library, please see
+the INSTALL file, which should be in the same directory as this file.

+This file lists major changes which accompany each new release.
+
+Version 1.4.1:
+
+  This is a maintenance release. It includes minor changes to support
+  Mac OS X (Darwin), the QNX real-time operating system, and Cygwin
+  under Windows. It also fixes an oversight that was preventing the
+  tab key from inserting tab characters when users unbound the
+  complete-word action from it.
+
+Version 1.4.0:
+
+  The contents of the history list can now be saved and restored with
+  the new gl_save_history() and gl_load_history() functions.
+
+  Event handlers can now be registered to watch for and respond to I/O
+  on arbitrary file descriptors while gl_get_line() is waiting for
+  terminal input from the user. See the gl_get_line(3) man page
+  for details on gl_watch_fd().
+
+  As an optional alternative to getting configuration information only
+  from ~/.teclarc, the new gl_configure_getline() function allows
+  configuration commands to be taken from any of, a string, a
+  specified application-specific file, and/or a specified
+  user-specific file. See the gl_get_line(3) man page for details.
+
+  The version number of the library can now be queried using the
+  libtecla_version() function. See the libtecla(3) man page.
+
+  The new gl_group_history() function allows applications to group
+  different types of input line in the history buffer, and arrange for
+  only members of the appropriate group to be recalled on a given call
+  to gl_get_line(). See the gl_get_line(3) man page.
+
+  The new gl_show_history() function displays the current history list
+  to a given stdio output stream. See the gl_get_line(3) man page.
+
+  new_GetLine() now allows you to specify a history buffer size of
+  zero, thus requesting that no history buffer be allocated. You can
+  subsequently resize or delete the history buffer at any time, by
+  calling gl_resize_history(), limit the number of lines that are
+  allowed in the buffer by calling gl_limit_history(), clear either
+  all history lines from the history list, or just the history lines
+  that are associated with the current history group, by calling
+  gl_clear_history, and toggle the history mechanism on and off by
+  calling gl_toggle_history().
+
+  The new gl_terminal_size() function can be used to query the
+  current terminal size. It can also be used to supply a default
+  terminal size on systems where no mechanism is available for
+  looking up the size.
+
+  The contents and configuration of the history list can now be
+  obtained by the calling application, by calling the new
+  gl_lookup_history(), gl_state_of_history(), gl_range_of_history()
+  and gl_size_of_history() functions. See the gl_get_line(3) man page.
+
+  Echoing of the input line as it is typed, can now be turned on and
+  off via the new gl_echo_mode() function. While echoing is disabled,
+  newly entered input lines are omitted from the history list.  See
+  the gl_get_line(3) man page.
+
+  While the default remains to display the prompt string literally,
+  the new gl_prompt_style() function can be used to enable text
+  attribute formatting directives in prompt strings, such as
+  underlining, bold font, and highlighting directives.
+
+  Signal handling in gl_get_line() is now customizable. The default
+  signal handling behavior remains essentially the same, except that
+  the SIGTSTP, SIGTTIN and SIGTTOU are now forwarded to the
+  corresponding signal handler of the calling program, instead of
+  causing a SIGSTOP to be sent to the application.  It is now possible
+  to remove signals from the list that are trapped by gl_get_line(),
+  as well as add new signals to this list. The signal and terminal
+  environments in which the signal handler of the calling program is
+  invoked, and what gl_get_line() does after the signal handler
+  returns, is now customizable on a per signal basis. You can now also
+  query the last signal that was caught by gl_get_line(). This is
+  useful when gl_get_line() aborts with errno=EINTR, and you need to
+  know which signal caused it to abort.
+
+  Key-sequences bound to action functions can now start with printable
+  characters. Previously only keysequences starting with control or
+  meta characters were permitted.
+
+  gl_get_line() is now 8-bit clean. If the calling program has
+  correctly called setlocale(LC_CTYPE,""), then the user can select an
+  alternate locale by setting the standard LC_CTYPE, LC_ALL, or LANG
+  environment variables, and international characters can then be
+  entered directly, either by using a non-US keyboard, or by using a
+  compose key on a standard US keyboard. Note that in locales in which
+  meta characters become printable, meta characters no longer match
+  M-c bindings, which then have to be entered using their escape-c
+  equivalents.  Fortunately most modern terminal emulators either
+  output the escape-c version by default when the meta key is used, or
+  can be configured to do so (see the gl_get_line(3) man page), so in
+  most cases you can continue to use the meta key.
+
+  Completion callback functions can now tell gl_get_line() to return
+  the input line immediately after a successful tab completion, simply
+  by setting the last character of the optional continuation suffix to
+  a newline character (ie. in the call to cpl_add_completion()).
+
+  It is now safe to create and use multiple GetLine objects, albeit
+  still only from a single thread. In conjunction with the new
+  gl_configure_getline() function, this optionally allows multiple
+  GetLine objects with different bindings to be used to implement
+  different input modes.
+
+  The edit-mode configuration command now accepts the argument,
+  none. This tells gl_get_line() to revert to using just the native
+  line editing facilities provided by the terminal driver. This could
+  be used if the termcap or terminfo entry of the host terminal were
+  badly corrupted.
+
+  Application callback functions invoked by gl_get_line() can now
+  change the displayed prompt using the gl_replace_prompt() function.
+
+  Their is now an optional program distributed with the library. This
+  is a beta release of a program which adds tecla command-line editing
+  to virtually any third party application without the application
+  needing to be linked to the library. See the enhance(3) man page for
+  further details. Although built and installed by default, the
+  INSTALL document explains how to prevent this.
+
+  The INSTALL document now explains how you can stop the demo programs
+  from being built and installed.
+
+  NetBSD/termcap fixes. Mike MacFaden reported two problems that he
+  saw when compiling libtecla under NetBSD. Both cases were related to
+  the use of termcap.  Most systems use terminfo, so this problem has
+  gone unnoticed until now, and won't have affected the grand majority
+  of users.  The configure script had a bug which prevented the check
+  for CPP working properly, and getline.c wouldn't compile due to an
+  undeclared variable when USE_TERMCAP was defined. Both problems have
+  now been fixed. Note that if you successfully compiled version
+  1.3.3, this problem didn't affect you.
+
+  An unfortunate and undocumented binding of the key-sequence M-O was
+  shadowing the arrow-key bindings on systems that use ^[OA etc. I
+  have removed this binding (the documented lower case M-o binding
+  remains bound). Under the KDE konsole terminal this was causing the
+  arrow keys to do something other than expected.
+
+  There was a bug in the history list code which could result in
+  strange entries appearing at the start of the history list once
+  enough history lines had been added to the list to cause the
+  circular history buffer to wrap. This is now fixed.
+ 
+Version 1.3.3:
+
+  Signal handling has been re-written, and documentation of its
+  behaviour has been added to the gl_get_line(3) man page. In addition
+  to eliminating race conditions, and appropriately setting errno for
+  those signals that abort gl_get_line(), many more signals are now
+  intercepted, making it less likely that the terminal will be left in
+  raw mode by a signal that isn't trapped by gl_get_line().
+
+  A bug was also fixed that was leaving the terminal in raw mode if
+  the editing mode was changed interactively between vi and emacs.
+  This was only noticeable when running programs from old shells that
+  don't reset terminal modes.
+
+Version 1.3.2:
+
+  Tim Eliseo contributed a number of improvements to vi mode,
+  including a fuller set of vi key-bindings, implementation of the vi
+  constraint that the cursor can't backup past the point at which
+  input mode was entered, and restoration of overwritten characters
+  when backspacing in overwrite mode. There are also now new bindings
+  to allow users to toggle between vi and emacs modes interactively.
+  The terminal bell is now used in some circumstances, such as when an
+  unrecognized key sequence is entered. This can be turned off by the
+  new nobeep option in the tecla configuration file.
+
+  Unrelated to the above, a problem under Linux which prevented ^Q
+  from being used to resume terminal output after the user had pressed
+  ^S, has been fixed.
+
+Version 1.3.1:
+
+  In vi mode a bug was preventing the history-search-backward and
+  history-search-forward actions from doing anything when invoked on
+  empty lines. On empty lines they now act like up-history and
+  down-history respectively, as in emacs mode.
+
+  When creating shared libraries under Linux, the -soname directive
+  was being used incorrectly. The result is that Linux binaries linked
+  with the 1.2.3, 1.2.4 and 1.3.0 versions of the tecla shared
+  libraries, will refuse to see other versions of the shared library
+  until relinked with version 1.3.1 or higher.
+
+  The configure script can now handle the fact that under Solaris-2.6
+  and earlier, the only curses library is a static one that hides in
+  /usr/ccs/lib. Under Linux it now also caters for old versions of GNU
+  ld which don't accept version scripts.
+
+  The demos are now linked against the shared version of the library
+  if possible. Previously they were always linked with the static
+  version.
+
+Version 1.3.0:
+
+  The major change in this release is the addition of an optional vi
+  command-line editing mode in gl_get_line(), along with lots of new
+  action functions to support its bindings. To enable this, first
+  create a ~/.teclarc file if you don't already have one, then add the
+  following line to it.
+
+   edit-mode vi
+
+  The default vi bindings, which are designed to mimic those of the vi
+  editor as closely as possible, are described in the gl_get_line(3)
+  man page.
+
+  A new convenience function called ef_list_expansions() has been
+  added for listing filename expansions. See the ef_list_expansions(3)
+  man page for details. This is used in a new list-glob binding, bound
+  to ^Xg in emacs mode, and ^G in vi input mode.
+
+  A bug has been fixed in the key-binding table expansion code. This
+  bug would have caused problems to anybody who defined more than
+  about 18 personalized key-bindings in their ~/.teclarc file.
+
+Version 1.2.4:
+
+  Buffered I/O is now used for writing to terminals, and where
+  supported, cursor motion is done with move-n-positions terminfo
+  capabilities instead of doing lots of move-1-position requests. This
+  greatly improves how the library feels over slow links.
+
+  You can now optionally compile different architectures in different
+  directories, without having to make multiple copies of the
+  distribution. This is documented in the INSTALL file.
+
+  The ksh ~+ directive is now supported.
+
+  Thanks to Markus Gyger for the above improvements.
+
+  Documentation has been added to the INSTALL file describing features
+  designed to facilitate configuration and installation of the library
+  as part of larger packages. These features are intended to remove
+  the need to modify the tecla distribution's configuration and build
+  procedures when embedding the libtecla distribution in other package
+  distributions.
+
+  A previous fix to stop the cursor from warping when the last
+  character of the input line was in the last column of the terminal,
+  was only being used for the first terminal line of the input line.
+  It is now used for all subsequent lines as well, as originally
+  intended.
+  
+Version 1.2.3:
+
+  The installation procedure has been better automated with the
+  addition of an autoconf configure script. This means that installers
+  can now compile and install the library by typing:
+
+    ./configure
+    make
+    make install
+
+  On all systems this makes at least the normal static version of the
+  tecla library. It also makes the reentrant version if reentrant
+  POSIX functions are detected.  Under Solaris, Linux and HP-UX the
+  configuration script arranges for shared libraries to be compiled in
+  addition to the static libraries.  It is hoped that installers will
+  return information about how to compile shared libraries on other
+  systems, for inclusion in future releases, and to this end, a new
+  PORTING guide has been provided.
+
+  The versioning number scheme has been changed. This release would
+  have been 1.2c, but instead will be refered to as 1.2.3. The
+  versioning scheme, based on conventions used by Sun Microsystems, is
+  described in configure.in.
+
+  The library was also tested under HP-UX, and this revealed two
+  serious bugs, both of which have now been fixed.
+  
+  The first bug prevented the library from writing control codes to
+  terminals on big-endian machines, with the exception of those
+  running under Solaris. This was due to an int variable being used
+  where a char was needed.
+
+  The second bug had the symptom that on systems that don't use the
+  newline character as the control code for moving the cursor down a
+  line, a newline wasn't started when the user hit enter.
+
+Version 1.2b:
+
+  Two more minor bug fixes:
+
+  Many terminals don't wrap the cursor to the next line when a
+  character is written to the rightmost terminal column. Instead, they
+  delay starting a new line until one more character is written, at
+  which point they move the cursor two positions.  gl_get_line()
+  wasn't aware of this, so cursor repositionings just after writing
+  the last character of a column, caused it to erroneously go up a
+  line. This has now been remedied, using a method that should work
+  regardless of whether a terminal exhibits this behavior or not.
+
+  Some systems dynamically record the current terminal dimensions in
+  environment variables called LINES and COLUMNS. On such systems,
+  during the initial terminal setup, these values should override the
+  static values read from the terminal information databases, and now
+  do.  Previously they were only used if the dimensions returned by
+  terminfo/termcap looked bogus.
+
+Version 1.2a:
+
+  This minor release fixes the following two bugs:
+
+  The initial terminal size and subsequent changes thereto, weren't
+  being noticed by gl_get_line(). This was because the test for the
+  existence of TIOCWINSZ was erroneously placed before the inclusion
+  of termios.h. One of the results was that on input lines that
+  spanned more than one terminal line, the cursor occasionally jumped
+  unexpectedly to the previous terminal line.
+
+  On entering a line that wrapped over multiple terminal lines,
+  gl_get_line() simply output a carriage-return line-feed at the point
+  at which the user pressed return. Thus if one typed in such a line,
+  then moved back onto one of the earlier terminal lines before
+  hitting return, the cursor was left on a line containing part of the
+  line that had just been entered. This didn't do any harm, but it
+  looked a mess.
+
+Version 1.2:
+
+  A new facility for looking up and completing filenames in UNIX-style
+  paths has now been added (eg. you can search for, or complete
+  commands using the UNIX PATH environment variable). See the
+  pca_lookup_file(3) man page.
+
+  The already existing filename completion callback can now be made
+  selective in what types of files it lists. See the
+  cpl_complete_word(3) man page.
+
+  Due to its potential to break applications when changed, the use of
+  the publically defined CplFileArgs structure to configure the
+  cpl_file_completions() callback is now deprecated.  The definition
+  of this structure has been frozen, and its documentation has been
+  removed from the man pages.  It will remain supported, but if you
+  have used it, you are recommended to switch to the new method, which
+  involves a new opaque configuration object, allocated via a provided
+  constructor function, configured via accessor functions, and
+  eventually deleted with a provided destructor function. The
+  cpl_file_completions() callback distinguishes which structure type
+  it has been sent by virtue of a code placed at the start of the new
+  structure by the constructor.  It is assumed that no existing
+  applications set the boolean 'escaped' member of the CplFileArgs
+  structure to 4568.  The new method is documented in the
+  cpl_complete_word(3) man page.
+
+Version 1.1j
+
+  This was the initial public release on freshmeat.org.

+<BODY bgcolor=add8e6><PRE>
+In the following log, modification dates are listed using the European
+convention in which the day comes before the month (ie. DD/MM/YYYY).
+The most recent modifications are listed first.
+
+25/05/2002 mcs@astro.caltech.edu  (based on suggestions by Paul Smith)
+           pathutil.c
+             Apparently, under QNX pathconf("/",_PC_PATH_MAX) returns
+             EINVAL. At Paul's suggestion I have modified the code to
+             silently substitute the existing MAX_PATHLEN_FALLBACK
+             value if pathconf() returns an error of any kind.
+           homedir.c
+             Under QNX, sysconf(_SC_GETPW_R_SIZE_MAX) also apparently
+             returns EINVAL, so as with pathconf() I modified the code
+             to substitute a fallback default, rather than
+             complaining and failing.
+           enhance.c
+             Paul told me that the inclusion of sys/termios.h was
+             causing compilation of enhance.c to fail under QNX. This
+             line is a bug.  The correct thing to do is include
+             termios.h without a sub-directory prefix, as I was
+             already doing futher up in the file, so I have just
+             removed the errant include line.
+
+12/02/2002 mcs@astro.caltech.edu
+           getline.c configure.in configure
+             Mac OS X doesn't have a term.h or termcap.h, but it does
+             define prototypes for tputs() and setupterm(), so the
+             default prototypes that I was including if no headers
+             where available, upset it. I've removed these prototypes.
+             I also now conditionally include whichever is found of
+             curses.h and ncurses/curses.h for both termcap and
+             terminfo (before I wasn't including curses.h when
+             termcap was selected).
+
+12/02/2002 mcs@astro.caltech.edu
+           Updated version number to 1.4.1, ready for a micro
+           release.
+
+12/02/2002 mcs@astro.caltech.edu
+           html/index.html
+             Added Mac OS X and Cygwin to the list of systems that
+             can compile libtecla.
+
+12/02/2002 mcs@astro.caltech.edu
+           getline.c
+             Under Mac OS X, the tputs() callback function returns
+             void, instead of the int return value used by other
+             systems. This declaration is now used if both __MACH__
+             and __APPLE__ are defined. Hopefully these are the
+             correct system macros to check. Thanks for Stephan
+             Fiedler for providing information on Mac OS X.
+
+11/02/2002 mcs@astro.caltech.edu
+           configure.in configure getline.c
+             Some systems don't have term.h, and others have it hidden
+             in an ncurses sub-directory of the standard system include
+             directory. If term.h can't be found, simply don't include
+             it. If it is in an ncurses sub-directory, include
+             ncurses/term.h instead of term.h.
+
+04/02/2002 mcs@astro.caltech.edu
+           configure.in configure Makefile.in Makefile.rules
+             Use ranlib on systems that need it (Mac OS X).  Also,
+             make all components of the installation directories where
+             needed, instead of assuming that they exist.
+
+04/02/2002 mcs@astro.caltech.edu
+           getline.c
+             When the tab completion binding was unbound from the tab
+             key, hitting the tab key caused gl_get_line() to ring the
+             bell instead of inserting a tab character. This is
+             problematic when using the 'enhance' program with
+             Jython, since tabs are important in Python. I have
+             corrected this.
+
+10/12/2001 Version 1.4.0 released.
+
+10/12/2001 mcs@astro.caltech.edu
+           getline.c
+             If the TIOCGWINSZ ioctl doesn't work, as is the case when
+             running in an emacs shell, leave the size unchanged, rather
+             than returning a fatal error.
+
+07/12/2001 mcs@astro.caltech.edu
+           configure.in configure
+             Now that the configure version of CFLAGS is included in
+             the makefile, I noticed that the optimization flags -g
+             and -O2 had been added. It turns out that if CFLAGS isn't
+             already set, the autoconf AC_PROG_CC macro initializes it
+             with these two optimization flags. Since this would break
+             backwards compatibility in embedded distributions that
+             already use the OPT= makefile argument, and because
+             turning debugging on needlessly bloats the library, I now
+             make sure that CFLAGS is set before calling this macro.
+
+07/12/2001 mcs@astro.caltech.edu
+           enhance.c
+             Use argv[0] in error reports instead of using a
+             hardcoded macro.
+
+07/12/2001 mcs@astro.caltech.edu
+           getline.c
+             The cut buffer wasn't being cleared after being
+             used as a work buffer by gl_load_history().
+
+06/12/2001 mcs@astro.caltech.edu
+           configure.in configure
+             I removed my now redundant definition of SUN_TPUTS from
+             CFLAGS. I also added "-I/usr/include" to CFLAGS under
+             Solaris to prevent gcc from seeing conflicting versions
+             of system header files in /usr/local/include.
+
+06/12/2001 Markus Gyger (logged here by mcs)
+           Lots of files.
+             Lots of corrections to misspellings and typos in the
+             comments.
+           getline.c
+             Markus reverted a supposed fix that I added a day or two
+             ago. I had incorrectly thought that in Solaris 8, Sun had
+             finally brought their declaration of the callback
+             function of tputs() into line with other systems, but it
+             turned out that gcc was pulling in a GNU version of
+             term.h from /usr/local/include, and this was what
+             confused me.
+
+05/12/2001 mcs@astro.caltech.edu
+           Makefile.in
+             I added @CFLAGS@ to the CFLAGS assignment, so that
+             if CFLAGS is set as an environment variable when
+             configure is run, the corresponding make variable
+             includes its values in the output makefile.
+
+05/12/2001 mcs@astro.caltech.edu
+           getline.c libtecla.h libtecla.map man3/gl_get_line.3
+           man3/gl_last_signal.3
+             I added a function that programs can use to find out
+             which signal caused gl_get_line() to return EINTR.
+
+05/12/2001 mcs@astro.caltech.edu
+           getline.c
+             When the newline action was triggered by a printable
+             character, it failed to display that character. It now
+             does. Also, extra control codes that I had added, to
+             clear to the end of the display after the carriage return,
+             but before displaying the prompt, were confusing expect
+             scripts, so I have removed them. This step is now done
+             instead in gl_redisplay() after displaying the full input
+             line.
+
+05/12/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             A user convinced me that continuing to invoke meta
+             keybindings for meta characters that are printable is a
+             bad idea, as is allowing users to ask to have setlocale()
+             called behind the application's back. I have thus changed
+             this. The setlocale configuration option has gone, and
+             gl_get_line() is now completely 8-bit clean, by default.
+             This means that if a meta character is printable, it is
+             treated as a literal character, rather than a potential
+             M-c binding.  Meta bindings can still be invoked via
+             their Esc-c equivalents, and indeed most terminal
+             emulators either output such escape pairs by default when
+             the meta character is pressed, or can be configured to do
+             so. I have documented how to configure xterm to do this,
+             in the man page.
+
+03/12/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             gl_get_line() by default now prints any 8-bit printable
+             characters that don't match keybindings. Previously
+             characters > 127 were only printed if preceded by the
+             literal-next action.  Alternatively, by placing the
+             command literal_if_printable in the tecla configuration
+             file, all printable characters are treated as literal
+             characters, even if they are bound to action functions.
+
+             For international users of programs written by
+             programmers that weren't aware of the need to call
+             setlocale() to support alternate character sets, the
+             configuration file can now also contain the single-word
+             command "setlocale", which tells gl_get_line() to remedy
+             this.
+
+27/11/2001 mcs@astro.caltech.edu
+           demo.c demo2.c enhance man3/gl_get_line.3
+             All demos and programs now call setlocale(LC_CTYPE,"").
+             This makes them support character sets of different
+             locales, where specified with the LC_CTYPE, LC_ALL, or
+             LANG environment variables. I also added this to the demo
+             in the man page, and documented its effect.
+
+27/11/2001 mcs@astro.caltech.edu
+           getline.c
+             When displaying unsigned characters with values over
+             127 literally, previously it was assumed that they would
+             all be displayable. Now isprint() is consulted, and if it
+             says that a character isn't printable, the character code
+             is displayed in octal like \307. In non-C locales, some
+             characters with values > 127 are displayable, and
+             isprint() tells gl_get_line() which are and which aren't.
+
+27/11/2001 mcs@astro.caltech.edu
+           getline.c pathutil.c history.c enhance.c demo2.c
+             All arguments of the ctype.h character class functions
+             are now cast to (int)(unsigned char). Previously they
+             were cast to (int), which doesn't correctly conform to
+             the requirements of the C standard, and could cause
+             problems for characters with values > 127 on systems
+             with signed char's.
+
+26/11/2001 mcs@astro.caltech.edu
+           man3/enhance.3 man3/libtecla.3
+             I started writing a man page for the enhance program.
+
+26/11/2001 mcs@astro.caltech.edu
+           Makefile.in Makefile.rules INSTALL
+             It is now possible to specify whether the demos and other
+             programs are to be built, by overriding the default
+             values of the DEMOS, PROGRAMS and PROGRAMS_R variables.
+             I have also documented the BINDIR variable and the
+             install_bin makefile target.
+
+22/11/2001 mcs@astro.caltech.edu
+           getline.c libtecla.h libtecla.map man3/gl_get_line.3
+           man3/gl_ignore_signal.3 man3/gl_trap_signal.3
+             Signal handling has now been modified to be customizable.
+             Signals that are trapped by default can be removed from
+             the list of trapped signals, and signals that aren't
+             currently trapped, can be added to the list. Applications
+             can also specify the signal and terminal environments in
+             which an application's signal handler is invoked, and
+             what gl_get_line() does after the signal handler returns.
+
+13/11/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             Added half-bright, reverse-video and blinking text to the
+             available prompt formatting options.
+           getline.c
+             Removed ^O from the default VT100 sgr0 capability
+             string.  Apparently it can cause problems with some
+             terminal emulators, and we don't need it, since it turns
+             off the alternative character set mode, which we don't
+             use.
+           getline.c
+             gl_tigetstr() and gl_tgetstr() didn't guard against the
+             error returns of tigetstr() and tgetstr() respectively.
+             They now do.
+
+11/11/2001 mcs@astro.caltech.edu
+           getline.c libtecla.h libtecla.map man3/gl_get_line.3
+           man3/gl_prompt_style.3
+             Although the default remains to display the prompt string
+             literally, the new gl_prompt_style() function can be used
+             to enable text attribute formatting directives in prompt
+             strings, such as underlining, bold font, and highlighting
+             directives.
+
+09/11/2001 mcs@astro.caltech.edu
+           enhance.c Makefile.rules configure.in configure
+             I added a new program to the distribution that allows one
+             to run most third party programs with the tecla library
+             providing command-line editing.
+
+08/11/2001 mcs@astro.caltech.edu
+           libtecla.h getline.c man3/gl_get_line.3 history.c history.h
+             I added a max_lines argument to gl_show_history() and
+             _glh_show_history(). This can optionally be used to
+             set a limit on the number of history lines displayed.
+           libtecla.h getline.c man3/gl_get_line.3
+             I added a new function called gl_replace_prompt(). This
+             can be used by gl_get_line() callback functions to
+             request that a new prompt be use when they return.
+
+06/11/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             I implemented, bound and documented the list-history
+             action, used for listing historical lines of the current
+             history group.
+           getline.c man3/gl_get_line.3 man3/gl_echo_mode.3
+             I wrote functions to specify and query whether subsequent
+             lines will be visible as they are being typed.
+
+28/10/2001 mcs@astro.caltech.edu
+           getline.c man3/gl_get_line.3
+             For those cases where a terminal provides its own
+             high-level terminal editing facilities, you can now
+             specify an edit-mode argument of 'none'. This disables
+             all tecla key bindings, and by using canonical terminal
+             input mode instead of raw input mode, editing is left up
+             to the terminal driver.
+
+21/10/2001 mcs@astro.caltech.edu
+           libtecla.h getline.c history.c history.h
+           man3/gl_get_line.3 man3/gl_history_info.3
+             I added the new gl_state_of_history(),
+             gl_range_of_history() and gl_size_of_history()
+             functions for querying information about the
+             history list.
+           history.c
+             While testing the new gl_size_of_history()
+             function, I noticed that when the history buffer
+             wrapped, any location nodes of old lines between
+             the most recent line and the end of the buffer
+             weren't being removed. This could result in bogus
+             entries appearing at the start of the history list.
+             Now fixed.
+
+20/10/2001 mcs@astro.caltech.edu
+
+           libtecla.h getline.c history.c history.h
+           man3/gl_get_line.3 man3/gl_lookup_history.3
+             I added a function called gl_lookup_history(), that
+             the application can use to lookup lines in the history
+             list.
+           libtecla.h getline.c history.c history.h man3/gl_get_line.3
+             gl_show_history() now takes a format string argument
+             to control how the line is displayed, and with what
+             information. It also now provides the option of either
+             displaying all history lines or just those of the
+             current history group.
+           getline.c man3/gl_get_line.3
+             gl_get_line() only archives lines in the history buffer
+             if the newline action was invoked by a newline or
+             carriage return character.
+

+           man3/gl_limit_history.3 man3/gl_clear_history.3
+           man3/gl_toggle_history.3
+	     I added a number of miscellaneous history configuration
+	     functions. You can now resize or delete the history
+	     buffer, limit the number of lines that are allowed in the
+	     buffer, clear either all history or just the history of
+	     the current history group, and temporarily enable and
+	     disable the history mechanism.

+

+             tputs_fp is now only declared if using termcap or

+           man3/gl_terminal_size.3
+             I added a public gl_terminal_size() function for
+             updating and querying the current size of the terminal.
+           update_version configure.in libtecla.h
+             A user noted that on systems where the configure script
+             couldn't be used, it was inconvenient to have the version
+             number macros set by the configure script, so they are
+             now specified in libtecla.h. To reduce the likelihood
+             that the various files where the version number now
+             appears might get out of sync, I have written the
+             update_version script, which changes the version number
+             in all of these files to a given value.

+             I added a max_lines argument to gl_save_history(), to
+             allow people to optionally place a ceiling on the number
+             of history lines saved. Specifying this as -1 sets the

+             with the current stream identification number, and

+           getline.c
+             Previously new_GetLine() installed a persistent signal
+             handler to be sure to catch the SIGWINCH (terminal size
+             change) signal between calls to gl_get_line(). This had
+             the drawback that if multiple GetLine objects were
+             created, only the first GetLine object used after the
+             signal was received, would see the signal and adapt to
+             the new terminal size. Instead of this, a signal handler
+             for sigwinch is only installed while gl_get_line() is
+             running, and just after installing this handler,
+             gl_get_line() checks for terminal size changes that
+             might have occurred while the signal handler wasn't
+             installed.

+             Dynamically allocated copies of capability strings looked

+             that calls to setupterm() etc for one GetLine object
+             don't get trashed when another GetLine object calls
+             setupterm() etc. It is now safe to allocate and use
+             multiple GetLine objects, albeit only within a single

+           configure.in
+             There was a bug in the configure script that only
+             revealed itself on systems without termcap but not
+             terminfo (eg. NetBSD). I traced the bug back to a lack of
+             sufficient quoting of multi-line m4 macro arguments in
+             configure.in, and have now fixed this and recreated the
+             configure script.

+           getline.c
+             getline.c wouldn't compile when termcap was selected as

+             passed a non-existent variable, in place of the term[]
+             argument of gl_control_strings(). Also if
+             gl_change_terminal() is called with term==NULL, "ansi"
+             is now substituted.

+           getline.c
+             gl_change_terminal() was being called by gl_change_editor(),
+             with the unwanted side effect that raw terminal modes were
+             stored as those to be restored later, if called by an
+             action function. gl_change_terminal() was being called in
+             this case to re-establish terminal-specific key bindings,
+             so I have just split this part of the function out into
+             a separate function for both gl_change_editor() and
+             gl_change_terminal() to call.
+
+12/06/2001 mcs@astro.caltech.edu
+
+           getline.c
+             Signal handling has been improved. Many more signals are
+             now trapped, and instead of using a simple flag set by a
+             signal handler, race conditions are avoided by blocking
+             signals during most of the gl_get_line() code, and
+             unblocking them via calls to sigsetjmp(), just before
+             attempting to read each new character from the user.
+             The matching use of siglongjmp() in the signal
+             handlers ensures that signals are reblocked correctly
+             before they are handled. In most cases, signals cause
+             gl_get_line() to restore the terminal modes and signal
+             handlers of the calling application, then resend the
+             signal to the application. In the case of SIGINT, SIGHUP,
+             SIGPIPE, and SIGQUIT, if the process still exists after
+             the signals are resent, gl_get_line() immediately returns
+             with appropriate values assigned to errno. If SIGTSTP,
+             SIGTTIN or SIGTTOU signals are received, the process is
+             suspended. If any other signal is received, and the
+             process continues to exist after the signal is resent to
+             the calling application, line input is resumed after the
+             terminal is put back into raw mode, the gl_get_line()
+             signal handling is restored, and the input line redrawn.
+           man/gl_get_line(3)
+             I added a SIGNAL HANDLING section to the gl_get_line()
+             man page, describing the new signal handling features.

+           getline.c
+             When vi-replace-char was used to replace the character at

+             its right instead of on top of it. Now rememdied.
+           getline.c
+             When undoing, to properly emulate vi, the cursor is now
+             left at the leftmost of the saved and current cursor
+             positions.

+
+           getline.c man3/gl_get_line.3
+             Implemented and documented the vi-repeat-change action,
+             bound to the period key. This repeats the last action
+             that modified the input line.
+
+19/05/2001 mcs@astro.caltech.edu
+
+           man3/gl_get_line.3
+             I documented the new action functions and bindings
+             provided by Tim Eliseo, plus the ring-bell action and
+             the new "nobeep" configuration option.
+           getline.c
+             I modified gl_change_editor() to remove and reinstate the
+             terminal settings as well as the default bindings, since
+             these have editor-specific differences. I also modified
+             it to not abort if a key-sequence can't be bound for some
+             reason. This allows the new vi-mode and emacs-mode
+             bindings to be used safely.
+           getline.c
+             When the line was re-displayed on receipt of a SIGWINCH
+             signal, the result wasn't visible until the next
+             character was typed, since a call to fflush() was needed.
+             gl_redisplay_line() now calls gl_flush_output() to remedy
+             this.
+
+17/05/2001 mcs@astro.catlech.edu
+
+           getline.c
+             Under Linux, calling fflush(gl->output_fd) hangs if
+             terminal output has been suspended with ^S. With the
+             tecla library taking responsability for reading the stop
+             and start characters this was a problem, because once
+             hung in fflush(), the keyboard input loop wasn't entered,
+             so the user couldn't type the start character to resume
+             output.  To remedy this, I now have the terminal process
+             these characters, rather than the library.
+
+12/05/2001 mcs@astro.caltech.edu
+
+           getline.c
+             The literal-next action is now implemented as a single
+             function which reads the next character itself.
+             Previously it just set a flag which effected the
+             interpretation of the next character read by the input
+             loop.
+           getline.c
+             Added a ring-bell action function. This is currently
+             unbound to any key by default, but it is used internally,
+             and can be used by users that want to disable any of the
+             default key-bindings.
+
+12/05/2001 Tim Eliseo    (logged here by mcs)
+
+           getline.c
+             Don't reset gl->number until after calling an action
+             function. By looking at whether gl->number is <0 or
+             not, action functions can then tell whether the count
+             that they were passed was explicitly specified by the
+             user, as opposed to being defaulted to 1.
+           getline.c
+             In vi, the position at which input mode is entered
+             acts as a barrier to backward motion for the few
+             backward moving actions that are enabled in input mode.
+             Tim added this barrier to getline.
+           getline.c
+             In gl_get_line() after reading an input line, or
+             having the read aborted by a signal, the sig_atomic_t
+             gl_pending_signal was being compared to zero instead
+             of -1 to see if no signals had been received.
+             gl_get_line() will thus have been calling raise(-1),
+             which luckily didn't seem to do anything. Tim also
+             arranged for errno to be set to EINTR when a signal
+             aborts gl_get_line().
+           getline.c
+             The test in gl_add_char_to_line() for detecting
+             when overwriting a character with a wider character,
+             had a < where it needed a >. Overwriting with a wider
+             character thus overwrote trailing characters. Tim also
+             removed a redundant copy of the character into the
+             line buffer.
+           getline.c
+             gl_cursor_left() and gl->cursor_right() were executing
+             a lot of redundant code, when the existing call to the
+             recently added gl_place_cursor() function, does all that
+             is necessary.
+           getline.c
+             Remove redundant code from backward_kill_line() by
+             re-implimenting in terms of gl_place_cursor() and
+             gl_delete_chars().
+           getline.c
+             gl_forward_delete_char() now records characters in cut
+             buffer when in vi command mode.
+           getline.c
+             In vi mode gl_backward_delete_char() now only deletes
+             up to the point at which input mode was entered. Also
+             gl_delete_chars() restores from the undo buffer when
+             deleting in vi insert mode.
+           getline.c
+             Added action functions, vi-delete-goto-column,
+             vi-change-to-bol, vi-change-line, emacs-mode, vi-mode,

+             links to be created as well, before linking the
+             demos. Without this the demos always linked to the
+             static libraries (which was perfectly ok, but wasn't a

+           Makefile.in Makefile.rules
+             On systems on which shared libraries were being created,

+             problem.
+           Makefile.rules
+             The demos now relink to take account of changes to the
+             library.
+           configure.in configure
+             When determining whether the reentrant version of the
+             library should be compiled by default, the configure
+             script now attempts to compile a dummy program that
+             includes all of the appropriate system headers and
+             defines _POSIX_C_SOURCE. This should now be a robust test
+             on systems which use C macros to alias these function
+             names to other internal functions.
+           configure.in
+             Under Solaris 2.6 and earlier, the curses library is in
+             /usr/ccs/lib. Gcc wasn't finding this. In addition to
+             remedying this, I had to remove "-z text" from
+             LINK_SHARED under Solaris to get it to successfully
+             compile the shared library against the static curses
+             library.
+           configure.in
+             Under Linux the -soname directive was being used
+             incorrectly, citing the fully qualified name of the
+             library instead of its major version alias. This will
+             unfortunately mean that binaries linked with the 1.2.3
+             and 1.2.4 versions of the shared library won't use
+             later versions of the library unless relinked.

+
+           configure.in
+             I removed the --no-undefined directive from the Linux
+             LINK_SHARED command. After recent patches to our RedHat
+             7.0 systems ld started reporting some internal symbols of
+             libc as being undefined.  Using nm on libc indicated that
+             the offending symbols are indeed defined, albeit as
+             "common" symbols, so there appears to be a bug in
+             RedHat's ld. Removing this flag allows the tecla shared
+             library to compile, and programs appear to function fine.
+           man3/gl_get_line.3
+             The default key-sequence used to invoke the
+             read-from-file action was incorrectly cited as ^Xi
+             instead of ^X^F.
+
+26/04/2001 mcs@astro.caltech.edu
+
+           getline.c man3/gl_get_line.3
+             A new vi-style editing mode was added. This involved
+             adding many new action functions, adding support for
+             specifying editing modes in users' ~/.teclarc files,
+             writing a higher level cursor motion function to support
+             the different line-end bounds required in vi command
+             mode, and a few small changes to support the fact that vi
+             has two modes, input mode and command mode with different
+             bindings.
+
+             When vi editing mode is enabled, any binding that starts
+             with an escape or a meta character, is interpreted as a
+             command-mode binding, and switches the library to vi
+             command mode if not already in that mode. Once in command
+             mode the first character of all keysequences entered
+             until input mode is re-enabled, are quietly coerced to
+             meta characters before being looked up in the key-binding
+             table. So, for example, in the key-binding table, the
+             standard vi command-mode 'w' key, which moves the cursor
+             one word to the right, is represented by M-w. This
+             emulates vi's dual sets of bindings in a natural way
+             without needing large changes to the library, or new
+             binding syntaxes. Since cursor keys normally emit
+             keysequences which start with escape, it also does
+             something sensible when a cursor key is pressed during
+             input mode (unlike true vi, which gets upset).
+
+             I also added a ^Xg binding for the new list-glob action
+             to both the emacs and vi key-binding tables. This lists
+             the files that match the wild-card expression that
+             precedes it on the command line.
+
+             The function that reads in ~/.teclarc used to tell
+             new_GetLine() to abort if it encountered anything that it
+             didn't understand in this file. It now just reports an
+             error and continues onto the next line.
+           Makefile.in:
+             When passing LIBS=$(LIBS) to recursive invokations of
+             make, quotes weren't included around the $(LIBS) part.
+             This would cause problems if LIBS ever contained more
+             than one word (with the supplied configure script this
+             doesn't happen currently). I added these quotes.
+           expand.c man3/ef_expand_file.3:
+             I wrote a new public function called ef_list_expansions(),
+             to list the matching filenames returned by
+             ef_expand_file().
+
+             I also fixed the example in the man page, which cited
+             exp->file instead of exp->files, and changed the
+             dangerous name 'exp' with 'expn'.
+           keytab.c:
+             Key-binding tables start with 100 elements, and are
+             supposedly incremented in size by 100 elements whenever
+             the a table runs out of space. The realloc arguments to
+             do this were wrong. This would have caused problems if
+             anybody added a lot of personal bindings in their
+             ~/.teclarc file. I only noticed it because the number of
+             key bindings needed by the new vi mode exceeded this
+             number.
+           libtecla.map
+             ef_expand_file() is now reported as having been added in

+             To allow the library to be compiled with a C++ compiler,

+             void* return values were being assigned directly to
+             none void* pointer variables.

+
+           libtecla.map:

+             Also added cpl_init_FileArgs to the list of exported
+             symbols. This symbol is deprecated, and no longer
+             documented, but for backwards compatibility, it should
+             still be exported.

+             A couple of the function prototypes in libtecla.h have

+             needs to be included. The header file should be self
+             contained, so libtecla.h now includes stdio.h.

+             The fix for the end-of-line problem that I released a
+             couple of weeks ago, only worked for the first line,
+             because I was handling this case when the cursor position
+             was equal to the last column, rather than when the cursor
+             position modulo ncolumn was zero.
+           Makefile.in Makefile.rules

+           INSTALL
+             I documented how to compile the library in a different
+             directory than the distribution directory.
+             I also documented features designed to facilitate
+             configuring and building the library as part of another
+             package.
+
+17/03/2001 Markus Gyger (logged here by mcs)
+
+           getline.c
+             Until now cursor motions were done one at a time. Markus
+             has added code to make use the of the terminfo capability
+             that moves the cursor by more than one position at a
+             time. This greatly improves performance when editing near
+             the start of long lines.
+           getline.c
+             To further improve performance, Markus switched from
+             writing one character at a time to the terminal, using
+             the write() system call, to using C buffered output
+             streams. The output buffer is only flushed when
+             necessary.
+           Makefile.rules Makefile.in configure.in
+             Added support for compiling for different architectures
+             in different directories. Simply create another directory
+             and run the configure script located in the original
+             directory.
+           Makefile.in configure.in libtecla.map
+             Under Solaris, Linux and HP-UX, symbols that are to be
+             exported by tecla shared libraries are explicitly specified
+             via symbol map files. Only publicly documented functions
+             are thus visible to applications.
+           configure.in
+             When linking shared libraries under Solaris SPARC,
+             registers that are reserved for applications are marked
+             as off limits to the library, using -xregs=no%appl when
+             compiling with Sun cc, or -mno-app-regs when compiling
+             with gcc. Also removed -z redlocsym for Solaris, which
+             caused problems under some releases of ld.
+           homedir.c  (after minor changes by mcs)
+             Under ksh, ~+ expands to the current value of the ksh
+             PWD environment variable, which contains the path of
+             the current working directory, including any symbolic
+             links that were traversed to get there. The special
+             username "+" is now treated equally by tecla, except
+             that it substitutes the return value of getcwd() if PWD
+             either isn't set, or if it points at a different
+             directory than that reported by getcwd().

+
+08/03/2001 mcs@astro.caltech.edu
+
+           getline.c
+             On compiling the library under HP-UX for the first time
+             I encountered and fixed a couple of bugs:
+
+             1. On all systems except Solaris, the callback function
+                required by tputs() takes an int argument for the
+                character that is to be printed. Under Solaris it
+                takes a char argument. The callback function was
+                passing this argument, regardless of type, to write(),
+                which wrote the first byte of the argument.  This was
+                fine under Solaris and under little-endian systems,
+                because the first byte contained the character to be
+                written, but on big-endian systems, it always wrote
+                the zero byte at the other end of the word. As a
+                result, no control characters were being written to
+                the terminal.
+             2. While attempting to start a newline after the user hit
+                enter, the library was outputting the control sequence
+                for moving the cursor down, instead of the newline
+                character. On many systems the control sequence for
+                moving the cursor down happends to be a newline
+                character, but under HP-UX it isn't. The result was
+                that no new line was being started under HP-UX.

+             Configuration and compilation of the library is now
+             performed with the help of an autoconf configure
+             script. In addition to relieving the user of the need to
+             edit the Makefile, this also allows automatic compilation
+             of the reentrant version of the library on platforms that
+             can handle it, along with the creation of shared
+             libraries where configured. On systems that aren't known
+             to the configure script, just the static tecla library is
+             compiled. This is currently the case on all systems
+             except Linux, Solaris and HP-UX. In the hope that
+             installers will provide specific conigurations for other
+             systems, the configure.in script is heavily commented,
+             and instructions on how to use are included in a new

+
+           getline.c
+             It turns out that most terminals, but not all, on writing
+             a character in the rightmost column, don't wrap the
+             cursor onto the next line until the next character is
+             output. This library wasn't aware of this and thus if one
+             tried to reposition the cursor from the last column,
+             gl_get_line() thought that it was moving relative to a
+             point on the next line, and thus moved the cursor up a
+             line. The fix was to write one extra character when in
+             the last column to force the cursor onto the next line,
+             then backup the cursor to the start of the new line.
+           getline.c
+             On terminal initialization, the dynamic LINES and COLUMNS
+             environment variables were ignored unless
+             terminfo/termcap didn't return sensible dimensions. In
+             practice, when present they should override the static
+             versions in the terminfo/termcap databases. This is the
+             new behavior. In reality this probably won't have caused
+             many problems, because a SIGWINCH signal which informs of
+             terminal size changes is sent when the terminal is
+             opened, so the dimensions established during
+             initialization quickly get updated on most systems.

+             Three months ago I moved the point at which termios.h
+             was included in getline.c. Unfortunately, I didn't notice
+             that this moved it to after the test for TIOCGWINSZ being
+             defined. This resulted in SIGWINCH signals not being
+             trapped for, and thus terminal size changes went
+             unnoticed. I have now moved the test to after the 
+             inclusion of termios.h.

+             In the 1.2 release of the library, all functions in the

+             include one of the above 4 man pages, which describe the
+             functions while describing the modules that they are in.
+             Markus added all of these function names to the lists in
+             the "NAME" headers of the respective man pages.
+             Previously only the primary function of each module was

+             On entering a line that wrapped over two or more
+             terminal, if the user pressed enter when the cursor
+             wasn't on the last of the wrapped lines, the text of the
+             wrapped lines that followed it got mixed up with the next
+             line written by the application, or the next input
+             line. Somehow this slipped through the cracks and wasn't
+             noticed until now. Anyway, it is fixed now.

+           pcache.c libtecla.h
+             With all filesystems local, demo2 was very fast to start
+             up, but on a Sun system with one of the target
+             directories being on a remote nfs mounted filesystem, the
+             startup time was many seconds. This was due to the
+             executable selection callback being applied to all files
+             in the path at startup. To avoid this, all files are now
+             included in the cache, and the application specified
+             file-selection callback is only called on files as they
+             are matched. Whether the callback rejected or accepted
+             them is then cached so that the next time an already
+             checked file is looked at, the callback doesn't have to
+             be called. As a result, startup is now fast on all
+             systems, and since usually there are only a few matching
+             file completions at a time, the delay during completion
+             is also usually small. The only exception is if the user
+             tries to complete an empty string, at which point all
+             files have to be checked. Having done this once, however,
+             doing it again is fast.
+           man3/pca_lookup_file.3
+             I added a man page documenting the new PathCache module.
+           man3/<many-new-files>.3
+             I have added man pages for all of the functions in each
+             of the modules. These 1-line pages use the .so directive
+             to redirect nroff to the man page of the parent module.
+           man Makefile update_html
+             I renamed man to man3 to make it easier to test man page
+             rediction, and updated Makefile and update_html
+             accordingly. I also instructed update_html to ignore
+             1-line man pages when making html equivalents of the man
+             pages.

+             strlen() was being used as the length argument of a "%*s"
+             printf directive. This ought to be an int, so the return
+             value of strlen() is now cast to int. This would have
+             caused problems on architectures where the size of a
+             size_t is not equal to the size of an int.

+           getline.c
+             Under UNIX, certain terminal bindings are set using the
+             stty command. This, for example, specifies which control
+             key generates a user-interrupt (usually ^C or ^Y). What I
+             hadn't realized was that ASCII NUL is used as the way to
+             specify that one of these bindings is unset. I have now
+             modified the code to skip unset bindings, leaving the
+             corresponding action bound to the built-in default, or a
+             user provided binding.
+
+28/01/2001 mcs@astro.caltech.edu
+
+           pcache.c libtecla.h
+             A new module was added which supports searching for files
+             in any colon separated list of directories, such as the
+             unix execution PATH environment variable. Files in these
+             directories, after being individually okayed for
+             inclusion via an application provided callback, are
+             cached in a PathCache object. You can then look up the
+             full pathname of a given filename, or you can use the
+             provided completion callback to list possible completions
+             in the path-list. The contents of relative directories,
+             such as ".", obviously can't be cached, so these
+             directories are read on the fly during lookups and
+             completions. The obvious application of this facility is
+             to provide Tab-completion of commands, and thus a
+             callback to place executable files in the cache, is
+             provided.
+           demo2.c
+             This new program demonstrates the new PathCache
+             module. It reads and processes lines of input until the
+             word 'exit' is entered, or C-d is pressed. The default
+             tab-completion callback is replaced with one which at the
+             start of a line, looks up completions of commands in the
+             user's execution path, and when invoked in other parts of
+             the line, reverts to normal filename completion. Whenever
+             a new line is entered, it extracts the first word on the
+             line, looks it up in the user's execution path to see if
+             it corresponds to a known command file, and if so,
+             displays the full pathname of the file, along with the
+             remaining arguments.
+           cplfile.c
+             I added an optional pair of callback function/data
+             members to the new cpl_file_completions() configuration
+             structure. Where provided, this callback is asked
+             on a file-by-file basis, which files should be included
+             in the list of file completions. For example, a callback
+             is provided for listing only completions of executable
+             files.
+           cplmatch.c
+             When listing completions, the length of the type suffix
+             of each completion wasn't being taken into account
+             correctly when computing the column widths. Thus the
+             listing appeared ragged sometimes. This is now fixed.
+           pathutil.c
+             I added a function for prepending a string to a path,
+             and another for testing whether a pathname referred to
+             an executable file.

+           libtecla.h cplmatch.c man/cpl_complete_word.3
+             The use of a publically defined structure to configure
+             the cpl_file_completions() callback was flawed, so a new
+             approach has been designed, and the old method, albeit
+             still supported, is no longer documented in the man
+             pages. The definition of the CplFileArgs structure in
+             libtecla.h is now accompanied by comments warning people
+             not to modify it, since modifications could break
+             applications linked to shared versions of the tecla
+             library. The new method involves an opaque CplFileConf
+             object, instances of which are returned by a provided
+             constructor function, configured with provided accessor
+             functions, and when no longer needed, deleted with a
+             provided destructor function. This is documented in the
+             cpl_complete_word man page. The cpl_file_completions()
+             callback distinguishes what type of configuration
+             structure it has been sent by virtue of a code placed at
+             the beginning of the CplFileConf argument by its
+             constructor.

+
+           getline.c
+             I added upper-case bindings for the default meta-letter
+             keysequences such as M-b. They thus continue to work
+             when the user has caps-lock on.
+           Makefile
+             I re-implemented the "install" target in terms of new
+             install_lib, install_inc and install_man targets. When
+             distributing the library with other packages, these new
+             targets allows for finer grained control of the
+             installation process.

+
+           getline.c man/gl_get_line.3
+             I realized that the recall-history action that I
+             implemented wasn't what Markus had asked me for. What he
+             actually wanted was for down-history to continue going
+             forwards through a previous history recall session if no
+             history recall session had been started while entering
+             the current line. I have thus removed the recall-history
+             action and modified the down-history action function
+             accordingly.
+
+24/12/2000 mcs@astro.caltech.edu
+
+           getline.c
+             I modified gl_get_line() to allow the previously returned

+           getline.c man/gl_get_line.3
+             I added a recall-history action function, bound to M^P.
+             This recalls the last recalled history line, regardless
+             of whether it was from the current or previous line.
+
+13/12/2000 mcs@astro.caltech.edu (Release of version 1.1i)
+
+           getline.c history.h history.c man/gl_get_line.3
+             I implemented the equivalent of the ksh Operate action. I
+             have named the tecla equivalent "repeat-history". This
+             causes the line that is to be edited to returned, and
+             arranges for the next most recent history line to be
+             preloaded on the next call to gl_get_line(). Repeated
+             invocations of this action thus result in successive
+             history lines being repeated - hence the
+             name. Implementing the ksh Operate action was suggested
+             by Markus Gyger. In ksh it is bound to ^O, but since ^O
+             is traditionally bound by the default terminal settings,
+             to stop-output, I have bound the tecla equivalent to M-o.
+
+01/12/2000 mcs@astro.caltech.edu (Release of version 1.1h)
+
+           getline.c keytab.c keytab.h man/gl_get_line.3
+             I added a digit-argument action, to allow repeat
+             counts for actions to be entered. As in both tcsh
+             and readline, this is bound by default to each of
+             M-0, M-1 through to M-9, the number being appended
+             to the current repeat count. Once one of these has been
+             pressed, the subsequent digits of the repeat count can be
+             typed with or without the meta key pressed. It is also
+             possible to bind digit-argument to other keys, with or
+             without a numeric final keystroke. See man page for
+             details.
+
+           getline.c man/gl_get_line.3
+             Markus noted that my choice of M-< for the default
+             binding of read-from-file, could be confusing, since
+             readline binds this to beginning-of-history. I have
+             thus rebound it to ^X^F (ie. like find-file in emacs).
+
+           getline.c history.c history.h man/gl_get_line.3
+             I have now implemented equivalents of the readline
+             beginning-of-history and end-of-history actions.
+             These are bound to M-< and M-> respectively.
+
+           history.c history.h
+             I Moved the definition of the GlHistory type, and
+             its subordinate types from history.h to history.c.
+             There is no good reason for any other module to
+             have access to the innards of this structure.

+27/11/2000 mcs@astro.caltech.edu (Release of version 1.1g)
+

+             I added a "read-from-file" action function and bound it
+             by default to M-<. This causes gl_get_line() to
+             temporarily return input from the file who's name
+             precedes the cursor.
+             
+26/11/2000 mcs@astro.caltech.edu
+
+           getline.c keytab.c keytab.h man/gl_get_line.3
+             I have reworked some of the keybinding code again.
+
+             Now, within key binding strings, in addition to the
+             previously existing notation, you can now use M-a to
+             denote meta-a, and C-a to denote control-a. For example,
+             a key binding which triggers when the user presses the
+             meta key, the control key and the letter [
+             simultaneously, can now be denoted by M-C-[, or M-^[ or
+             \EC-[ or \E^[.
+
+             I also updated the man page to use M- instead of \E in
+             the list of default bindings, since this looks cleaner.
+
+           getline.c man/gl_get_line.3
+             I added a copy-region-as-kill action function and
+             gave it a default binding to M-w.

+22/11/2000 mcs@astro.caltech.edu
+
+           *.c
+             Markus Gyger sent me a copy of a previous version of
+             the library, with const qualifiers added in appropriate
+             places. I have done the same for the latest version.
+             Among other things, this gets rid of the warnings
+             that are generated if one tells the compiler to
+             const qualify literal strings.
+
+           getline.c getline.h glconf.c
+             I have moved the contents of glconf.c and the declaration
+             of the GetLine structure into getline.c. This is cleaner,
+             since now only functions in getline.c can mess with the
+             innards of GetLine objects. It also clears up some problems
+             with system header inclusion order under Solaris, and also
+             the possibility that this might result in inconsistent
+             system macro definitions, which in turn could cause different
+             declarations of the structure to be seen in different files.
+
+           hash.c
+             I wrote a wrapper function to go around strcmp(), such that
+             when hash.c is compiled with a C++ compiler, the pointer
+             to the wrapper function is a C++ function pointer.
+             This makes it compatible with comparison function pointer
+             recorded in the hash table.
+
+           cplmatch.c getline.c libtecla.h
+             Markus noted that the Sun C++ compiler wasn't able to
+             match up the declaration of cpl_complete_word() in
+             libtecla.h, where it is surrounded by a extern "C" {}
+             wrapper, with the definition of this function in
+             cplmatch.c. My suspicion is that the compiler looks not
+             only at the function name, but also at the function
+             arguments to see if two functions match, and that the
+             match_fn() argument, being a fully blown function pointer
+             declaration, got interpetted as that of a C function in
+             one case, and a C++ function in the other, thus
+             preventing a match.
+
+             To fix this I now define a CplMatchFn typedef in libtecla.h,
+             and use this to declare the match_fn callback.
+
+20/11/2000 (Changes suggested by Markus Gyger to support C++ compilers):
+           expand.c
+             Renamed a variable called "explicit" to "xplicit", to
+             avoid conflicts when compiling with C++ compilers.
+           *.c
+             Added explicit casts when converting from (void *) to
+             other pointer types. This isn't needed in C but it is
+             in C++.
+           getline.c
+             tputs() has a strange declaration under Solaris. I was
+             enabling this declaration when the SPARC feature-test
+             macro was set. Markus changed the test to hinge on the
+             __sun and __SVR4 macros.
+           direader.c glconf.c stringrp.c
+             I had omitted to include string.h in these two files.
+
+           Markus also suggested some other changes, which are still
+           under discussion. With the just above changes however, the
+           library compiles without complaint using g++.

+           getline.h getline.c keytab.c keytab.h glconf.c
+           man/gl_get_line.3
+             I added support for backslash escapes (include \e
+             for the keyboard escape key) and literal binary
+             characters to the characters allowed within key sequences
+             of key bindings.
+
+           getline.h getline.c keytab.c keytab.h glconf.c
+           man/gl_get_line.3
+             I introduced symbolic names for the arrow keys, and
+             modified the library to use the cursor key sequences
+             reported by terminfo/termcap in addition to the default
+             ANSI ones. Anything bound to the symbolically named arrow
+             keys also gets bound to the default and terminfo/termcap
+             cursor key sequences. Note that under Solaris
+             terminfo/termcap report the properties of hardware X
+             terminals when TERM is xterm instead of the terminal
+             emulator properties, and the cursor keys on these two
+             systems generate different key sequences. This is an
+             example of why extra default sequences are needed.
+
+           getline.h getline.c keytab.c
+             For some reason I was using \e to represent the escape
+             character. This is supported by gcc, which thus doesn't
+             emit a warning except with the -pedantic flag, but isn't
+             part of standard C. I now use a macro to define escape
+             as \033 in getline.h, and this is now used wherever the
+             escape character is needed.

+
+           getline.c, man/gl_get_line(3), html/gl_get_line.html
+             In tcsh ^D is bound to a function which does different
+             things depending on where the cursor is within the input
+             line. I have implemented its equivalent in the tecla
+             library. When invoked at the end of the line this action
+             function displays possible completions. When invoked on
+             an empty line it causes gl_get_line() to return NULL,
+             thus signalling end of input. When invoked within a line
+             it invokes forward-delete-char, as before. The new action
+             function is called del-char-or-list-or-eof.
+
+           getline.c, man/gl_get_line(3), html/gl_get_line.html
+             I found that the complete-word and expand-file actions
+             had underscores in their names instead of hyphens. This
+             made them different from all other action functions, so I
+             have changed the underscores to hyphens.
+
+           homedir.c
+             On SCO UnixWare while getpwuid_r() is available, the
+             associated _SC_GETPW_R_SIZE_MAX macro used by sysconf()
+             to find out how big to make the buffer to pass to this
+             function to cater for any password entry, doesn't
+             exist. I also hadn't catered for the case where sysconf()
+             reports that this limit is indeterminate. I have thus
+             change the code to substitute a default limit of 1024 if
+             either the above macro isn't defined or if sysconf() says
+             that the associated limit is indeterminate.

+
+           getline.c, getline.h, history.c, history.h
+             I have modified the way that the history recall functions
+             operate, to make them better emulate the behavior of
+             tcsh. Previously the history search bindings always
+             searched for the prefix that preceded the cursor, then
+             left the cursor at the same point in the line, so that a
+             following search would search using the same prefix. This
+             isn't how tcsh operates. On finding a matching line, tcsh
+             puts the cursor at the end of the line, but arranges for
+             the followup search to continue with the same prefix,
+             unless the user does any cursor motion or character
+             insertion operations in between, in which case it changes
+             the search prefix to the new set of characters that are
+             before the cursor. There are other complications as well,
+             which I have attempted to emulate. As far as I can
+             tell, the tecla history recall facilities now fully
+             emulate those of tcsh.

+             now added #includes for the necessary system header files
+             in getline.h itself. The symptom was that on creating a
+             ~/.teclarc file, the demo program complained of a NULL
+             argument to kt_set_keybinding() for the first line of the
+             file.
+
+15/11/2000 mcs@astro.caltech.edu (Release of version 1.1a)
+
+           demo.c:
+             I had neglected to check the return value of
+             new_GetLine() in the demo program. Oops.
+
+           getline.c libtecla.h:
+             I wrote gl_change_terminal(). This allows one to change to
+             a different terminal or I/O stream, by specifying the
+             stdio streams to use for input and output, along with the
+             type of terminal that they are connected to.
+
+           getline.c libtecla.h:
+             Renamed GetLine::isterm to GetLine::is_term. Standard
+             C reserves names that start with "is" followed by
+             alphanumeric characters, so this avoids potential
+             clashes in the future.
+
+           keytab.c keytab.h
+             Each key-sequence can now have different binding
+             functions from different sources, with the user provided
+             binding having the highest precedence, followed by the
+             default binding, followed by any terminal specific
+             binding. This allows gl_change_terminal() to redefine the
+             terminal-specific bindings each time that
+             gl_change_terminal() is called, without overwriting the
+             user specified or default bindings. In the future, it will
+             also allow for reconfiguration of user specified
+             bindings after the call to new_GetLine(). Ie. deleting a
+             user specified binding should reinstate any default or
+             terminal specific binding.

+</pre><h2>DESCRIPTION</h2><pre>
+     The  cpl_complete_word()  function  is  part  of  the  tecla
+     library (see the <a href="libtecla.html">libtecla(3)</a> man page). It is usually called
+     behind the scenes by <a href="gl_get_line.html">gl_get_line(3)</a>, but can also be  called
+     separately.
+
+     Given an input line containing an incomplete word to be com-
+     pleted,  it  calls a user-provided callback function (or the
+     provided file-completion callback function) to look  up  all
+     possible  completion  suffixes  for  that word. The callback
+     function is expected to look backward in the line,  starting
+     from the specified cursor position, to find the start of the
+     word to be completed, then to look up all  possible  comple-
+     tions of that word and record them, one at a time by calling
+     cpl_add_completion().
+
+
+     Descriptions of the functions of this module are as follows:
+
+       CompleteWord *new_CompleteWord(void)
+
+     This  function   creates   the   resources   used   by   the
+     cpl_complete_word()  function.  In  particular, it maintains
+     the memory that is used to return  the  results  of  calling
+     cpl_complete_word().
+
+       CompleteWord *del_CompleteWord(CompleteWord *cpl)
+
+     This function deletes the resources that were returned by  a
+     previous  call to new_CompleteWord(). It always returns NULL
+     (ie. a deleted object). It does nothing if the cpl  argument
+     is NULL.
+
+     The callback functions  which  lookup  possible  completions
+     should be defined with the following macro (which is defined
+     in libtecla.h).
+
+       #define CPL_MATCH_FN(fn) int (fn)(WordCompletion *cpl, \
+                                         void *data, \
+                                         const char *line, \
+                                         int word_end)
+
+     Functions of this type are  called  by  cpl_complete_word(),
+     and all of the arguments of the callback are those that were
+     passed to said function. In particular,  the  line  argument
+     contains the input line containing the word to be completed,
+     and word_end is the index of the character that follows  the
+     last  character  of  the incomplete word within this string.
+     The callback is expected to look backwards from word_end for
+     the start of the incomplete word. What constitutes the start
+     of a word clearly depends on the application,  so  it  makes
+     sense  for  the callback to take on this responsibility. For
+     example, the  builtin  filename  completion  function  looks
+     backwards  until it hits an unescaped space, or the start of
+     the line.  Having found the start of the word, the  callback
+     should  then  lookup  all possible completions of this word,
+     and  record  each   completion   via   separate   calls   to
+     cpl_add_completion().  If  the  callback  needs access to an
+     application-specific symbol table, it can pass  it  and  any
+     other  data  that  it  needs,  via  the  data argument. This
+     removes any need for globals.
+
+     The callback function should return 0 if no errors occur. On
+     failure it should return 1, and register a terse description
+     of the error by calling cpl_record_error().
+
+       void cpl_record_error(WordCompletion *cpl,
+                             const char *errmsg);
+
+     The    last    error    message    recorded    by    calling
+     cpl_record_error(),  can  subsequently be queried by calling
+     cpl_last_error(), as described later.
+
+       int cpl_add_completion(WordCompletion *cpl,
+                              const char *line, int word_start,
+                              int word_end, const char *suffix,
+                              const char *type_suffix,
+                              const char *cont_suffix);
+
+     The cpl_add_completion() function is  called  zero  or  more
+     times  by  the  completion  callback function to record each
+     possible completion in the specified WordCompletion  object.
+     These    completions    are    subsequently    returned   by
+     cpl_complete_word(), as described later. The cpl, line,  and
+     word_end  arguments  should be those that were passed to the
+     callback function. The word_start  argument  should  be  the
+     index  within the input line string of the start of the word
+     that is being completed. This should  equal  word_end  if  a
+     zero-length  string  is being completed. The suffix argument
+     is the string that would have to be appended to  the  incom-
+     plete  word  to complete it.  If this needs any quoting (eg.
+     the addition of backslashes before special charaters) to  be
+     valid  within  the  displayed  input  line,  this  should be
+     included. A copy of the suffix string  is  allocated  inter-
+     nally,  so  there  is  no  need to maintain your copy of the
+     string after cpl_add_completion() returns.
+
+     Note that in the array of  possible  completions  which  the
+     cpl_complete_word() function returns, the suffix recorded by
+     cpl_add_completion() is listed along with the concatentation
+     of  this  suffix  with the word that lies between word_start
+     and word_end in the input line.
+
+     The type_suffix argument specifies an optional string to  be
+     appended  to  the completion if it is displayed as part of a
+     list of completions by cpl_list_completions(). The intention
+     is  that  this indicate to the user the type of each comple-
+     tion. For example, the file  completion  function  places  a
+     directory  separator after completions that are directories,
+     to indicate their nature to the user. Similary, if the  com-
+     pletion were a function, you could indicate this to the user
+     by setting type_suffix to "()". Note  that  the  type_suffix
+     string  isn't  copied,  so  if  the argument isn't a literal
+     string between speech marks, be sure that the string remains
+     valid   for   at   least   as   long   as   the  results  of
+     cpl_complete_word() are needed.
+
+     The cont_suffix is a continuation suffix to  append  to  the
+     completed word in the input line if this is the only comple-
+     tion. This is something that isn't part  of  the  completion
+     itself, but that gives the user an indication about how they
+     might continue to extend the token.  For example, the  file-
+     completion  callback  function adds a directory separator if
+     the completed word is a directory.  If  the  completed  word
+     were  a  function  name, you could similarly aid the user by
+     arranging for an open parenthesis to be appended.
+
+       CplMatches *cpl_complete_word(WordCompletion *cpl,
+                                     const char *line,
+                                     int word_end, void *data,
+                                     CplMatchFn *match_fn);
+
+     The cpl_complete_word() is normally called behind the scenes
+     by  <a href="gl_get_line.html">gl_get_line(3)</a>, but can also be called separately if you
+     separately allocate a  WordCompletion  object.  It  performs
+     word  completion, as described at the beginning of this sec-
+     tion. Its first argument is  a  resource  object  previously
+     returned  by  new_CompleteWord().   The line argument is the
+     input line string, containing the word to be completed.  The
+     word_end argument contains the index of the character in the
+     input line, that just follows the last character of the word
+     to  be  completed. When called by gl_get_line(), this is the
+     character over which the  user  pressed  TAB.  The  match_fn
+     argument  is  the  function pointer of the callback function
+     which will lookup  possible  completions  of  the  word,  as
+     described  above,  and  the data argument provides a way for
+     the application to pass arbitrary data to the callback func-
+     tion.
+
+     If no errors occur, the cpl_complete_word() function returns
+     a  pointer to a CplMatches container, as defined below. This
+     container is allocated as part of the cpl  object  that  was
+     passed  to cpl_complete_word(), and will thus change on each
+     call which uses the same cpl argument.

+       } CplMatch;

+       typedef struct {
+         char *suffix;            /* The common initial part */
+                                  /*  of all of the completion */
+                                  /*  suffixes. */

+                                  /*  completion strings, */
+                                  /*  sorted into lexical */
+                                  /*  order. */
+         int nmatch;              /* The number of elements in */
+                                  /*  the above matches[] */
+                                  /*  array. */
+       } CplMatches;
+
+     If an error occurs  during  completion,  cpl_complete_word()
+     returns  NULL. A description of the error can be acquired by
+     calling the cpl_last_error() function.
+
+       const char *cpl_last_error(WordCompletion *cpl);
+
+     The cpl_last_error() function returns a terse description of
+     the   error   which   occurred   on   the   last   call   to
+     cpl_complete_word() or cpl_add_completion().
+
+       int cpl_list_completions(CplMatches *result, FILE *fp,
+                                int terminal_width);
+
+     When the cpl_complete_word() function returns multiple  pos-
+     sible  completions,  the cpl_list_completions() function can
+     be called upon to list them, suitably  arranged  across  the
+     available  width  of  the  terminal.  It  arranges  for  the
+     displayed columns of completions to all have the same width,
+     set   by   the  longest  completion.  It  also  appends  the
+     type_suffix strings that were recorded with each completion,
+     thus indicating their types to the user.
+
+
+</pre><h2>THE BUILT-IN FILENAME-COMPLETION CALLBACK</h2><pre>
+     By default the <a href="gl_get_line.html">gl_get_line(3)</a> function, passes the following
+     completion  callback  function  to cpl_complete_word(). This
+     function can also be used separately, either by  sending  it
+     to  cpl_complete_word(), or by calling it directly from your
+     own completion callback function.
+
+       CPL_MATCH_FN(cpl_file_completions);
+
+     Certain aspects of the behavior  of  this  callback  can  be
+     changed  via  its  data  argument. If you are happy with its
+     default behavior you can pass NULL in this argument.  Other-
+     wise  it should be a pointer to a CplFileConf object, previ-
+     ously allocated by calling new_CplFileConf().
+
+       CplFileConf *new_CplFileConf(void);
+
+     CplFileConf objects encapsulate the configuration parameters
+     of cpl_file_completions(). These parameters, which start out
+     with default values, can be changed by calling the  accessor
+     functions described below.
+
+     By default,  the  cpl_file_completions()  callback  function
+     searches  backwards for the start of the filename being com-
+     pleted, looking for the first un-escaped space or the  start
+     of  the input line. If you wish to specify a different loca-
+     tion, call cfc_file_start() with  the  index  at  which  the
+     filename  starts  in  the input line. Passing start_index=-1
+     re-enables the default behavior.
+
+       void cfc_file_start(CplFileConf *cfc, int start_index);
+
+     By default, when cpl_file_completions() looks at a  filename
+     in  the input line, each lone backslash in the input line is
+     interpreted as being a special character which  removes  any
+     special significance of the character which follows it, such
+     as a space which should be taken as  part  of  the  filename
+     rather  than  delimiting  the  start  of the filename. These
+     backslashes are thus ignored while looking for  completions,
+     and  subsequently  added  before  spaces,  tabs  and literal
+     backslashes in the list of completions.  To  have  unescaped
+     backslashes    treated    as    normal    characters,   call
+     cfc_literal_escapes() with a non-zero value in  its  literal
+     argument.
+
+       void cfc_literal_escapes(CplFileConf *cfc, int literal);
+
+     By default, cpl_file_completions() reports all  files  who's
+     names  start with the prefix that is being completed. If you
+     only want a selected subset of these files to be reported in
+     the list of completions, you can arrange this by providing a
+     callback function which takes the full pathname of  a  file,
+     and  returns  0  if  the file should be ignored, or 1 if the
+     file should be included  in  the  list  of  completions.  To
+     register  such a function for use by cpl_file_completions(),
+     call cfc_set_check_fn(), and pass it a pointer to the  func-
+     tion,  together  with  a  pointer to any data that you would
+     like passed to this callback whenever  it  is  called.  Your
+     callback can make its decisions based on any property of the
+     file, such as the filename itself, whether the file is read-
+     able, writable or executable, or even based on what the file
+     contains.
+
+       #define CPL_CHECK_FN(fn) int (fn)(void *data, \
+                                         const char *pathname)

+                             CplCheckFn *chk_fn, void *chk_data);
+
+     The cpl_check_exe() function is a provided callback  of  the
+     above  type, for use with cpl_file_completions(). It returns
+     non-zero if the filename that it is given represents a  nor-

+     use this to have cpl_file_completions()  only  list  comple-
+     tions of executable files.
+
+     When you have finished with a CplFileConf variable, you  can
+     pass  it  to  the  del_CplFileConf()  destructor function to
+     reclaim its memory.

+
+
+</pre><h2>DESCRIPTION</h2><pre>
+     The ef_expand_file() function is part of the  tecla  library
+     (see  the  <a href="libtecla.html">libtecla(3)</a>  man  page).  It  expands a specified
+     filename, converting ~user/ and ~/ expressions at the  start
+     of  the  filename  to  the  corresponding  home directories,
+     replacing  $envvar  with  the  value  of  the  corresponding
+     environment  variable, and then, if there are any wildcards,
+     matching these against existing  filenames.  Backslashes  in
+     the  input  filename are interpreted as escaping any special
+     meanings  of  the  characters  that   follow   them.    Only
+     backslahes  that  are themselves preceded by backslashes are
+     preserved in the expanded filename.
+
+     In the presence of wildcards, the returned list of filenames
+     only  includes  the  names of existing files which match the
+     wildcards. Otherwise,  the  original  filename  is  returned
+     after  expansion  of  tilde  and dollar expressions, and the
+     result is not checked against existing  files.  This  mimics
+     the file-globbing behavior of the unix tcsh shell.
+
+     The supported wildcards and their meanings are:
+       *        -  Match any sequence of zero or more characters.
+       ?        -  Match any single character.
+       [chars]  -  Match any single character that appears in
+                   'chars'.  If 'chars' contains an expression of
+                   the form a-b, then any character between a and
+                   b, including a and b, matches. The '-'
+                   character looses its special meaning as a
+                   range specifier when it appears at the start
+                   of the sequence of characters. The ']'
+                   character also looses its significance as the
+                   terminator of the range expression if it
+                   appears immediately after the opening '[', at
+                   which point it is treated one of the
+                   characters of the range. If you want both '-'
+                   and ']' to be part of the range, the '-'
+                   should come first and the ']' second.
+
+       [^chars] -  The same as [chars] except that it matches any
+                   single character that doesn't appear in
+                   'chars'.
+
+     Note that wildcards never match the initial dot in filenames
+     that  start  with  '.'.  The  initial '.' must be explicitly
+     specified in the filename. This again  mimics  the  globbing
+     behavior  of  most unix shells, and its rational is based in
+     the fact that in unix, files with names that start with  '.'
+     are usually hidden configuration files, which are not listed
+     by default by the ls command.
+
+     The following is a complete example of how to use  the  file
+     expansion function.
+
+       #include &lt;stdio.h&gt;
+       #include &lt;libtecla.h&gt;
+
+       int main(int argc, char *argv[])
+       {
+         ExpandFile *ef;      /* The expansion resource object */
+         char *filename;      /* The filename being expanded */
+         FileExpansion *expn; /* The results of the expansion */
+         int i;
+
+         ef = new_ExpandFile();
+         if(!ef)
+           return 1;
+
+         for(arg = *(argv++); arg; arg = *(argv++)) {
+           if((expn = ef_expand_file(ef, arg, -1)) == NULL) {
+             fprintf(stderr, "Error expanding %s (%s).\n", arg,
+                              ef_last_error(ef));
+           } else {
+             printf("%s matches the following files:\n", arg);
+             for(i=0; i&lt;expn-&gt;nfile; i++)
+               printf(" %s\n", expn-&gt;files[i]);
+           }
+         }
+
+         ef = del_ExpandFile(ef);
+         return 0;
+       }
+
+     Descriptions of the functions used above are as follows:
+
+       ExpandFile *new_ExpandFile(void)
+
+     This  function   creates   the   resources   used   by   the
+     ef_expand_file()  function.  In particular, it maintains the
+     memory  that  is  used  to  record  the  array  of  matching
+     filenames  that  is returned by ef_expand_file(). This array
+     is expanded as needed, so there is no built in limit to  the
+     number of files that can be matched.
+
+       ExpandFile *del_ExpandFile(ExpandFile *ef)
+
+     This function deletes the resources that were returned by  a
+     previous  call  to  new_ExpandFile(). It always returns NULL
+     (ie a deleted object). It does nothing if the ef argument is
+     NULL.
+
+     A  container  of  the  following   type   is   returned   by
+     ef_expand_file().
+
+       typedef struct {
+         int exists;   /* True if the files in files[] exist */
+         int nfile;    /* The number of files in files[] */
+         char **files; /* An array of 'nfile' filenames. */
+       } FileExpansion;
+
+       FileExpansion *ef_expand_file(ExpandFile *ef,
+                                     const char *path,
+                                     int pathlen)
+
+     The ef_expand_file() function performs  filename  expansion,
+     as  documented at the start of this section. Its first argu-
+     ment is a resource object returned  by  new_ExpandFile().  A
+     pointer to the start of the filename to be matched is passed
+     via the path argument. This must be a normal NUL  terminated
+     string, but unless a length of -1 is passed in pathlen, only
+     the first pathlen characters will be used  in  the  filename
+     expansion.   If  the length is specified as -1, the whole of
+     the string will be expanded.
+
+     The function returns a pointer to a container who's contents
+     are the results of the expansion. If there were no wildcards
+     in the filename, the nfile member will be 1, and the  exists
+     member  should  be queried if it is important to know if the
+     expanded file currently exists or not. If there  were  wild-
+     cards,  then  the  contained  files[] array will contain the
+     names of the nfile existing files  that  matched  the  wild-
+     carded  filename,  and the exists member will have the value
+     1. Note that the returned container belongs to the specified
+     ef  object, and its contents will change on each call, so if
+     you need to retain the results of  more  than  one  call  to
+     ef_expand_file(),  you  should either make a private copy of
+     the returned  results,  or  create  multiple  file-expansion
+     resource objects via multiple calls to new_ExpandFile().
+
+     On error, NULL is returned, and an explanation of the  error
+     can be determined by calling ef_last_error(ef).
+
+       const char *ef_last_error(ExpandFile *ef)
+
+     This function returns the message which describes the  error
+     that  occurred on the last call to ef_expand_file(), for the
+     given (ExpandFile *ef) resource object.
+
+       int ef_list_expansions(FileExpansion *result, FILE *fp,
+                              int terminal_width);
+
+     The ef_list_expansions() function provides a convenient  way
+     to    list    the    filename    expansions    returned   by
+     ef_expand_file(). Like the unix ls command, it arranges  the
+     filenames  into  equal width columns, each column having the
+     width of the largest file. The number  of  columns  used  is
+     thus  determined  by the length of the longest filename, and
+     the specified terminal width. Beware that filenames that are
+     longer than the specified terminal width are printed without
+     being truncated, so output longer than the specified  termi-
+     nal width can occur. The list is written to the stdio stream
+     specified by the fp argument.

+</pre><h2>NAME</h2><pre>
+     enhance - A program that adds command-line editing to  third
+     party programs.
+
+</pre><h2>SYNOPSIS</h2><pre>
+     enhance command [ argument ... ]
+
+
+</pre><h2>DESCRIPTION</h2><pre>
+     The enhance program provides enhanced  command-line  editing
+     facilities  to  users  of third party applications, to which
+     one doesn't have any source code. It does this by placing  a
+     pseudo-terminal  between the application and the real termi-
+     nal. It uses the tecla command-line editing library to  read
+     input  from  the real terminal, then forwards each just com-
+     pleted  input  line  to  the  application  via  the  pseudo-
+     terminal.  All output from the application is forwarded back
+     unchanged to the real terminal.
+
+     Whenever the application stops generating  output  for  more
+     than  a  tenth  of  a second, the enhance program treats the
+     latest incomplete output line as the prompt, and  redisplays
+     any incompleted input line that the user has typed after it.
+     Note that the small delay, which  is  imperceptible  to  the
+     user,  isn't necessary for correct operation of the program.
+     It is just an optimization, designed to stop the input  line
+     from being redisplayed so often that it slows down output.
+
+
+</pre><h2>DEFICIENCIES</h2><pre>
+     The one major problem that hasn't been solved yet, is how to
+     deal  with  applications  that change whether typed input is
+     echo'd by their controlling terminal. For example,  programs
+     that ask for a password, such as ftp and telnet, temporarily
+     tell their controlling terminal not to echo  what  the  user
+     types.  Since  this  request goes to the application side of
+     the psuedo terminal, the enhance program has no way of know-
+     ing  that  this  has  happened,  and continues to echo typed
+     input to its controlling  terminal,  while  the  user  types
+     their password.
+
+     Furthermore, before  executing  the  host  application,  the
+     enhance program initially sets the pseudo terminal to noecho
+     mode, so that  everything  that  it  sends  to  the  program
+     doesn't  get  redundantly echoed. If a program that switches
+     to  noecho  mode  explicitly  restores  echoing  afterwards,
+     rather  than  restoring  the terminal modes that were previ-
+     ously in force, then subsequently, every time that you enter
+     a  new input line, a duplicate copy will be displayed on the
+     next line.

+</pre><h2>DESCRIPTION</h2><pre>
+     The gl_get_line() function is part of the tecla library (see
+     the <a href="libtecla.html">libtecla(3)</a> man page). If the user is typing at a termi-
+     nal, it prompts them for an line  of  input,  then  provides
+     interactive editing facilities, similar to those of the unix
+     tcsh shell. In addition to simple command-line  editing,  it
+     supports  recall  of  previously  entered command lines, TAB
+     completion of file names, and in-line wild-card expansion of
+     filenames.
+
+
+</pre><h2>AN EXAMPLE</h2><pre>
+     The following shows a complete example of  how  to  use  the
+     gl_get_line() function to get input from the user:
+
+       #include &lt;stdio.h&gt;
+       #include &lt;locale.h&gt;
+       #include &lt;libtecla.h&gt;
+       int main(int argc, char *argv[])
+       {
+         char *line;    /* The line that the user typed */
+         GetLine *gl;   /* The gl_get_line() resource object */
+
+         setlocale(LC_CTYPE, ""); /* Adopt the user's choice */
+                                  /* of character set. */
+
+         gl = new_GetLine(1024, 2048);
+         if(!gl)
+           return 1;
+
+         while((line=gl_get_line(gl, "$ ", NULL, -1)) != NULL &amp;&amp;
+                strcmp(line, "exit\n") != 0)
+           printf("You typed: %s\n", line);
+
+         gl = del_GetLine(gl);
+         return 0;
+       }
+
+     In  the  example,  first  the  resources   needed   by   the
+     gl_get_line() function are created by calling new_GetLine().
+     This allocates the memory used in subsequent  calls  to  the
+     gl_get_line()  function,  including  the  history buffer for
+     recording previously entered lines. Then one or  more  lines
+     are read from the user, until either an error occurs, or the
+     user types exit. Then finally the resources that were  allo-
+     cated  by  new_GetLine(), are returned to the system by cal-
+     ling del_GetLine(). Note the use of the NULL return value of
+     del_GetLine()  to make gl NULL. This is a safety precaution.
+     If  the  program  subsequently  attempts  to  pass   gl   to
+     gl_get_line(),  said  function  will complain, and return an
+     error, instead of attempting to  use  the  deleted  resource
+     object.
+
+
+
+</pre><h2>THE FUNCTIONS USED IN THE EXAMPLE</h2><pre>
+     The descriptions of the functions used in the example are as
+     follows:
+
+       GetLine *new_GetLine(size_t linelen, size_t histlen)
+
+     This  function   creates   the   resources   used   by   the
+     gl_get_line()  function and returns an opaque pointer to the
+     object that contains them.  The maximum length of  an  input
+     line  is  specified via the linelen argument, and the number
+     of bytes to allocate for storing history lines is set by the
+     histlen argument. History lines are stored back-to-back in a
+     single buffer of this size. Note that this  means  that  the
+     number  of  history  lines  that  can be stored at any given
+     time, depends on the lengths of the  individual  lines.   If
+     you want to place an upper limit on the number of lines that
+     can be stored, see the gl_limit_history() function described
+     later.  If you don't want history at all, specify histlen as
+     zero, and no history buffer will be allocated.
+
+     On error, a  message  is  printed  to  stderr  and  NULL  is
+     returned.
+
+       GetLine *del_GetLine(GetLine *gl)
+
+     This function deletes the resources that were returned by  a
+     previous call to new_GetLine(). It always returns NULL (ie a
+     deleted object). It does nothing if the gl argument is NULL.
+
+       char *gl_get_line(GetLine *gl, const char *prompt,
+                        const char *start_line, int start_pos);
+
+     The gl_get_line() function can be called any number of times
+     to  read input from the user. The gl argument must have been
+     previously returned by a call to new_GetLine().  The  prompt
+     argument  should be a normal NUL terminated string, specify-
+     ing the prompt to present the user with. By default  prompts
+     are   displayed   literally,   but   if   enabled  with  the
+     gl_prompt_style() function (see later), prompts can  contain
+     directives to do underlining, switch to and from bold fonts,
+     or turn highlighting on and off.
+
+     If you want to specify the initial contents of the line, for
+     the user to edit, pass the desired string via the start_line
+     argument. You can then specify which character of this  line
+     the cursor is initially positioned over, using the start_pos
+     argument. This should be -1 if you want the cursor to follow
+     the  last  character of the start line. If you don't want to
+     preload the line in this manner, send  start_line  as  NULL,
+     and set start_pos to -1.
+
+     The gl_get_line() function returns a  pointer  to  the  line
+     entered  by  the user, or NULL on error or at the end of the
+     input. The returned pointer is  part  of  the  specified  gl
+     resource  object,  and  thus  should  not  be  free'd by the
+     caller, or assumed to be unchanging from  one  call  to  the
+     next.  When  reading  from  a user at a terminal, there will
+     always be a newline character at the  end  of  the  returned
+     line.   When  standard input is being taken from a pipe or a
+     file, there will similarly be a  newline  unless  the  input
+     line  was  too  long to store in the internal buffer. In the
+     latter case you should call gl_get_line() again to read  the
+     rest   of   the   line.   Note   that  this  behavior  makes
+     gl_get_line() similar to fgets().  In fact when stdin  isn't
+     connected to a terminal,gl_get_line() just calls fgets().
+
+
+</pre><h2>OPTIONAL PROMPT FORMATTING</h2><pre>
+     Whereas by default the prompt string  that  you  specify  is
+     displayed  literally,  without any special interpretation of
+     the characters within it, the gl_prompt_style() function can
+     be  used to enable optional formatting directives within the
+     prompt.
+
+       void gl_prompt_style(GetLine *gl, GlPromptStyle style);
+
+     The style argument, which specifies  the  formatting  style,
+     can take any of the following values:
+
+       GL_FORMAT_PROMPT   -  In this style, the formatting
+                             directives described below, when
+                             included in prompt strings, are
+                             interpreted as follows:
+
+                               %B  -  Display subsequent
+                                      characters with a bold
+                                      font.
+                               %b  -  Stop displaying characters
+                                      with the bold font.
+                               %F  -  Make subsequent characters
+                                      flash.
+                               %f  -  Turn off flashing
+                                      characters.
+                               %U  -  Underline subsequent
+                                      characters.
+                               %u  -  Stop underlining
+                                      characters.
+                               %P  -  Switch to a pale (half
+                                      brightness) font.
+                               %p  -  Stop using the pale font.
+                               %S  -  Highlight subsequent
+                                      characters (also known as
+                                      standout mode).
+                               %s  -  Stop highlighting
+                                      characters.
+                               %V  -  Turn on reverse video.
+                               %v  -  Turn off reverse video.
+                               %%  -  Display a single %
+                                      character.
+
+                             For example, in this mode, a prompt
+                             string like "%UOK%u$ " would
+                             display the prompt "OK$ ",
+                             but with the OK part
+                             underlined.
+
+                             Note that although a pair of
+                             characters that starts with a %
+                             character, but doesn't match any of
+                             the above directives is displayed
+                             literally, if a new directive is
+                             subsequently introduced which does
+                             match, the displayed prompt will
+                             change, so it is better to always
+                             use %% to display a literal %.
+
+                             Also note that not all terminals
+                             support all of these text
+                             attributes, and that some substitute
+                             a different attribute for missing
+                             ones.
+
+       GL_LITERAL_PROMPT  -  In this style, the prompt string is
+                             printed literally. This is the
+                             default style.
+
+
+
+</pre><h2>THE AVAILABLE KEY BINDING FUNCTIONS</h2><pre>
+     The gl_get_line() function provides a  number  of  functions
+     which  can  be  bound  to  key sequences. The names of these
+     functions, and what they do, are given below.

+       abort                    -  Send a SIGABRT signal to the
+                                   parent process.
+       suspend                  -  Suspend the parent process.

+                                   character. This allows control
+                                   characters to be entered.
+       cursor-right             -  Move the cursor one character

+       beginning-of-line        -  Move the cursor to the
+                                   beginning of the line.
+       end-of-line              -  Move the cursor to the end of

+       delete-line              -  Delete the contents of the
+                                   current line.
+       kill-line                -  Delete everything that follows
+                                   the cursor.
+       backward-kill-line       -  Delete all characters between
+                                   the cursor and the start of the

+                                   which follows the cursor.
+       forward-to-word          -  Move the cursor to the start of
+                                   the word that follows the
+                                   cursor.
+       backward-word            -  Move to the start of the word
+                                   which precedes the cursor.
+       goto-column              -  Move the cursor to the
+                                   1-relative column in the line
+                                   specified by any preceding
+                                   digit-argument sequences (see
+                                   ENTERING REPEAT COUNTS below).
+       find-parenthesis         -  If the cursor is currently
+                                   over a parenthesis character,

+                                   parenthesis character. If not
+                                   over a parenthesis character
+                                   move right to the next close

+                                   to ^D. When invoked when the
+                                   cursor is within the line it
+                                   displays all possible
+                                   completions then redisplays
+                                   the line unchanged. When
+                                   invoked on an empty line, it
+                                   signals end-of-input (EOF) to
+                                   the caller of gl_get_line().
+       del-char-or-list-or-eof  -  This is intended for binding
+                                   to ^D. When invoked when the
+                                   cursor is within the line it
+                                   invokes forward-delete-char.
+                                   When invoked at the end of the
+                                   line it displays all possible
+                                   completions then redisplays

+                                   signals end-of-input (EOF) to
+                                   the caller of gl_get_line().
+       forward-delete-word      -  Delete the word which follows

+                                   the cursor.
+       upcase-word              -  Convert all of the characters
+                                   of the word which follows the
+                                   cursor, to upper case.
+       downcase-word            -  Convert all of the characters
+                                   of the word which follows the
+                                   cursor, to lower case.
+       capitalize-word          -  Capitalize the word which
+                                   follows the cursor.
+       change-case              -  If the next character is upper
+                                   case, toggle it to lower case
+                                   and vice versa.

+</pre><h2>DEFAULT KEY BINDINGS IN EMACS MODE</h2><pre>
+     The following default key bindings, which can  be  overriden
+     by  the tecla configuration file, are designed to mimic most
+     of the bindings of the unix tcsh shell, when it is in  emacs
+     editing mode.
+
+     This is the default editing mode of the tecla library.
+
+     Note that a key sequence like  ^A  or  C-a  means  hold  the
+     control-key down while pressing the letter A, and that where
+     you see \E or M- in a binding, this  represents  the  escape
+     key   or   the   Meta   modifier  key.  Also  note  that  to
+     gl_get_line(), pressing the  escape  key  before  a  key  is
+     equivalent to pressing the meta key at the same time as that
+     key. Thus the key sequence M-p can be typed in two ways,  by
+     pressing  the  escape  key,  followed  by  pressing p, or by
+     pressing the Meta key at the same time as p.
+
+     Under UNIX the terminal driver sets a number of special keys
+     for certain functions. The tecla library attempts to use the
+     same keybindings to maintain consistency. The key  sequences
+     shown for the following 6 bindings are thus just examples of
+     what they will probably be set to. If you have used the stty
+     command  to  change  these  keys,  then the default bindings
+     should match.

+
+
+</pre><h2>DEFAULT KEY BINDINGS IN VI MODE</h2><pre>
+     The following default key bindings are designed to mimic the
+     vi  style of editing as closely as possible. This means that
+     very few editing functions are provided in the initial char-
+     acter  input  mode, editing functions instead being provided
+     by the vi command mode. Vi command mode is entered  whenever
+     the  escape character is pressed, or whenever a key-sequence
+     that starts with a meta character is entered. In addition to
+     mimicing  vi, libtecla provides bindings for tab completion,
+     wild-card expansion  of  file  names,  and  historical  line
+     recall.
+
+     To learn how to tell  the  tecla  library  to  use  vi  mode
+     instead  of  the default emacs editing mode, see the section
+     entitled THE TECLA CONFIGURATION FILE.
+
+     As already mentioned above in the emacs section, Note that a
+     key  sequence like ^A or C-a means hold the control-key down
+     while pressing the letter A, and that where you see \E or M-
+     in  a  binding,  this  represents the escape key or the Meta
+     modifier key. Also note that to gl_get_line(), pressing  the
+     escape  key  before a key is equivalent to pressing the meta
+     key at the same time as that key. Thus the key sequence  M-p
+     can  be  typed in two ways, by pressing the escape key, fol-
+     lowed by pressing p, or by pressing the Meta key at the same
+     time as p.
+
+     Under UNIX the terminal driver sets a number of special keys
+     for certain functions. The tecla library attempts to use the
+     same keybindings to maintain consistency, binding them  both
+     in  input  mode and in command mode. The key sequences shown
+     for the following 6 bindings are thus just examples of  what
+     they will probably be set to. If you have used the stty com-
+     mand to change these keys, then the default bindings  should
+     match.

+       ^Q     -&gt;   start-output
+       ^S     -&gt;   stop-output
+       ^V     -&gt;   literal-next
+       M-^C   -&gt;   user-interrupt
+       M-^\   -&gt;   abort
+       M-^Z   -&gt;   suspend
+       M-^Q   -&gt;   start-output
+       M-^S   -&gt;   stop-output
+
+     Note that above, most of the  bindings  are  defined  twice,
+     once as a raw control code like ^C and then a second time as
+     a meta character like M-^C. The former is the binding for vi
+     input mode, whereas the latter is the binding for vi command
+     mode. Once in command mode all key-sequences that  the  user
+     types  that  they don't explicitly start with an escape or a
+     meta key, have their first key secretly converted to a  meta
+     character  before  the  key sequence is looked up in the key
+     binding table. Thus, once in command mode, when you type the
+     letter  i,  for example, the tecla library actually looks up
+     the binding for M-i.
+
+     The cursor keys are refered to by name, as follows. This  is
+     necessary because different types of terminals generate dif-
+     ferent key sequences when their cursor keys are pressed.
+
+       right  -&gt;   cursor-right
+       left   -&gt;   cursor-left
+       up     -&gt;   up-history
+       down   -&gt;   down-history
+
+     The cursor keys normally generate a keysequence  that  start
+     with  an  escape  character,  so beware that using the arrow
+     keys will put you into command mode (if you  aren't  already
+     in command mode).
+
+     The following are the terminal-independent key bindings  for
+     vi input mode.
+
+       ^D     -&gt;   list-or-eof
+       ^G     -&gt;   list-glob
+       ^H     -&gt;   backward-delete-char
+       ^I     -&gt;   complete-word
+       \r     -&gt;   newline
+       \n     -&gt;   newline
+       ^L     -&gt;   clear-screen
+       ^N     -&gt;   down-history
+       ^P     -&gt;   up-history
+       ^R     -&gt;   redisplay
+       ^U     -&gt;   backward-kill-line
+       ^W     -&gt;   backward-delete-word
+       ^X*    -&gt;   expand-filename
+       ^X^F   -&gt;   read-from-file
+       ^X^R   -&gt;   read-init-files
+       ^?     -&gt;   backward-delete-char
+
+     The following are the key bindings that are  defined  in  vi
+     command mode, this being specified by them all starting with
+     a meta character. As mentioned above, once in  command  mode
+     the  initial  meta  character  is optional. For example, you
+     might enter command mode by typing Esc,  and  then  press  h
+     twice  to  move the cursor two positions to the left. Both h
+     characters get quietly converted to M-h  before  being  com-
+     pared to the key-binding table, the first one because Escape
+     followed  by  a  character  is  always  converted   to   the
+     equivalent  meta  character,  and the second because command
+     mode was already active.

+
+
+</pre><h2>ENTERING REPEAT COUNTS</h2><pre>
+     Many of the key binding functions described previously, take
+     an  optional  count, typed in before the target keysequence.
+     This is interpreted as a repeat count by  most  bindings.  A
+     notable  exception  is the goto-column binding, which inter-
+     prets the count as a column number.
+
+     By default you can specify this count argument  by  pressing
+     the  meta key while typing in the numeric count. This relies
+     on the digit-argument action being bound to  Meta-0,  Meta-1
+     etc.  Once any one of these bindings has been activated, you
+     can optionally take your finger off the meta key to type  in
+     the rest of the number, since every numeric digit thereafter
+     is treated as part of the number, unless it is  preceded  by
+     the literal-next binding. As soon as a non-digit, or literal
+     digit key is pressed the  repeat  count  is  terminated  and
+     either  causes  the  just typed character to be added to the
+     line that many times, or causes the next  key-binding  func-
+     tion to be given that argument.
+
+     For example, in emacs mode, typing:
+
+       M-12a
+
+     causes the letter 'a' to be added  to  the  line  12  times,
+     whereas
+
+       M-4M-c
+
+     Capitalizes the next 4 words.
+
+     In vi command mode the Meta modifier is automatically  added
+     to  all  characters  typed  in,  so  to  enter a count in vi
+     command-mode, just involves typing in the number, just as at
+     it  does in the vi editor itself. So for example, in vi com-
+     mand mode, typing:
+
+       4w2x
+
+     moves the cursor four words to the right, then  deletes  two
+     characters.
+
+     You can also bind digit-argument to other key sequences.  If
+     these  end  in  a numeric digit, that digit gets appended to
+     the current repeat count. If it doesn't  end  in  a  numeric
+     digit,  a  new repeat count is started with a value of zero,
+     and can be completed by typing in the number, after  letting
+     go of the key which triggered the digit-argument action.
+
+
+</pre><h2>THE TECLA CONFIGURATION FILE</h2><pre>
+     By default, the first call to gl_get_line() looks for a file
+     called .teclarc in your home directory (ie. ~/.teclarc).  If
+     it finds this file, it reads it, interpreting each  line  as
+     defining  a  new  key  binding  or  an editing configuration
+     option.  Since  the  emacs  keybindings  are  installed   by
+     default, if you want to use the non-default vi editing mode,
+     the most important item to go in this file is the  following
+     line:
+
+       edit-mode vi
+
+     This will re-configure the default bindings for vi-mode. The
+     complete set of arguments that this command accepts are:
+
+       vi     -  Install key-bindings like those of the vi
+                 editor.
+       emacs  -  Install key-bindings like those of the emacs
+                 editor. This is the default.
+       none   -  Use just the native line editing facilities
+                 provided by the terminal driver.
+
+     To prevent the terminal bell from being rung, such  as  when
+     an unrecognized control-sequence is typed, place the follow-
+     ing line in the configuration file:
+
+       nobeep
+
+     An example of a key binding line in the  configuration  file
+     is the following.
+
+       bind M-[2~ insert-mode
+
+     On many keyboards, the above key sequence is generated  when
+     one presses the insert key, so with this keybinding, one can
+     toggle between the emacs-mode insert and overwrite modes  by
+     hitting  one  key.  One  could  also do it by typing out the
+     above sequence of characters one by one. As explained above,
+     the M- part of this sequence can be typed either by pressing
+     the escape key before the following key, or by pressing  the
+     Meta  key at the same time as the following key. Thus if you
+     had set the above key binding, and the insert  key  on  your
+     keyboard  didn't  generate the above key sequence, you could
+     still type it in either of the following 2 ways.
+
+       1. Hit the escape key momentarily, then press '[', then '2', then
+          finally '~'.
+
+       2. Press the meta key at the same time as pressing the '[' key,
+          then press '2', then '~'.
+
+     If you set a keybinding for a key-sequence that  is  already
+     bound  to a function, the new binding overrides the old one.
+     If in the new binding you omit the name of the new  function
+     to  bind  to  the key-sequence, the original binding becomes
+     undefined.
+
+     Starting with versions of libtecla later than  1.3.3  it  is
+     now  possible  to bind keysequences that begin with a print-
+     able character. Previously key-sequences  were  required  to
+     start with a control or meta character.
+
+     Note that the special  keywords  "up",  "down",  "left"  and
+     "right" refer to the arrow keys, and are thus not treated as
+     keysequences. So, for example, to rebind  the  up  and  down
+     arrow  keys  to  use the history search mechanism instead of
+     the simple history recall method, you could place  the  fol-
+     lowing in your configuration file:
+
+       bind up history-search-backwards
+       bind down history-search-backwards
+
+     To unbind an existing binding, you can do this with the bind
+     command  by  omitting  to  name any action to rebind the key
+     sequence to.  For example, by not specifying an action func-
+     tion,  the  following command unbinds the default beginning-
+     of-line action from the ^A key sequence:
+
+       bind ^A
+
+
+</pre><h2>ALTERNATE CONFIGURATION SOURCES</h2><pre>
+     As mentioned above, by default users have the option of con-
+     figuring  the  behavior of gl_get_line() via a configuration
+     file called .teclarc in their  home  directories.  The  fact
+     that  all applications share this same configuration file is
+     both an advantage and a disadvantage.  In most cases  it  is
+     an  advantage, since it encourages uniformity, and frees the
+     user from having to configure each  application  separately.
+     In  some  applications, however, this single means of confi-
+     guration is a problem. This is particularly true of embedded
+     software,  where  there's no filesystem to read a configura-
+     tion file from, and also in applications where  a  radically
+     different  choice  of  keybindings  is  needed  to emulate a
+     legacy keyboard interface.  To cater  for  such  cases,  the
+     following  function  allows the application to control where
+     configuration information is read from.
+
+
+       int gl_configure_getline(GetLine *gl,
+                                const char *app_string,
+                                const char *app_file,
+                                const char *user_file);
+
+
+     It allows the configuration commands that would normally  be
+     read  from  a user's ~/.teclarc file, to be read from any or
+     none of, a string,  an  application  specific  configuration
+     file,  and/or  a  user-specific  configuration file. If this
+     function is called before the first call  to  gl_get_line(),
+     the default behavior of reading ~/.teclarc on the first call
+     to gl_get_line() is disabled, so all configuration  must  be
+     achieved using the configuration sources specified with this
+     function.
+
+     If app_string != NULL, then it is interpreted  as  a  string
+     containing  one  or  more  configuration commands, separated
+     from each other in the string by  embedded  newline  charac-
+     ters. If app_file != NULL then it is interpreted as the full
+     pathname of an application-specific configuration  file.  If
+     user_file  !=  NULL then it is interpreted as the full path-
+     name  of  a  user-specific  configuration  file,   such   as
+     ~/.teclarc. For example, in the following call,
+
+       gl_configure_getline(gl, "edit-mode vi \n nobeep",
+                                "/usr/share/myapp/teclarc",
+                                "~/.teclarc");
+
+     the app_string argument causes the  calling  application  to
+     start  in  vi  edit-mode, instead of the default emacs mode,
+     and turns off the use of the terminal bell by  the  library.
+     It  then attempts to read system-wide configuration commands
+     from an optional file called /usr/share/myapp/teclarc,  then
+     finally  reads  user-specific configuration commands from an
+     optional .teclarc file in the user's  home  directory.  Note
+     that  the  arguments are listed in ascending order of prior-
+     ity, with the contents of app_string being potentially over-
+     riden  by  commands  in  app_file,  and commands in app_file
+     potentially being overriden by commands in user_file.
+     You can call this function as  many  times  as  needed,  the
+     results  being  cumulative,  but  note  that  copies  of any
+     filenames specified via the app_file and user_file arguments
+     are  recorded  internally  for  subsequent  use by the read-
+     init-files key-binding function, so if you plan to call this
+     function  multiple  times, be sure that the last call speci-
+     fies the filenames that  you  want  re-read  when  the  user
+     requests that the configuration files be re-read.
+
+
+</pre><h2>FILENAME AND TILDE COMPLETION</h2><pre>
+     With the default key bindings, pressing the  TAB  key  (aka.
+     ^I)  results  in  gl_get_line()  attempting  to complete the
+     incomplete filename that precedes the cursor.  gl_get_line()
+     searches backwards from the cursor, looking for the start of
+     the filename, stopping when it hits either a  space  or  the
+     start  of  the line. If more than one file has the specified
+     prefix, gl_get_line() completes the filename up to the point
+     at  which  the ambiguous matches start to differ, then lists
+     the possible matches.
+
+     In addition to literally  written  filenames,  gl_get_line()
+     can complete files that start with ~/ and ~user/ expressions
+     and that contain $envvar expressions. In particular, if  you
+     hit    TAB   within   an   incomplete   ~user,   expression,
+     gl_get_line() will attempt to complete the username, listing
+     any ambiguous matches.
+
+     The   completion   binding   is   implemented   using    the
+     cpl_word_completions()  function,  which  is  also available
+     separately   to   users   of   this   library.    See    the
+     cpl_word_completions(3) man page for more details.
+
+
+</pre><h2>CUSTOMIZED WORD COMPLETION</h2><pre>
+     If in your application, you would like to have  TAB  comple-
+     tion  complete  other  things  in  addition to or instead of
+     filenames, you can arrange this by registering an  alternate
+     completion   callback   function,   via   a   call   to  the
+     gl_customize_completion() function.
+
+       int gl_customize_completion(GetLine *gl, void *data,
+                                   CplMatchFn *match_fn);
+
+     The data argument provides a way  for  your  application  to
+     pass  arbitrary,  application-specific  information  to  the
+     callback function. This is passed to the callback every time
+     that it is called. It might for example, point to the symbol
+     table from which possible completions are to be sought.  The
+     match_fn  argument  specifies  the  callback  function to be
+     called.  The  CplMatchFn  function  type   is   defined   in
+     libtecla.h, as is a CPL_MATCH_FN() macro that you can use to
+     declare and prototype callback  functions.  The  declaration
+     and  responsibilities of callback functions are described in
+     depth in the <a href="cpl_complete_word.html">cpl_complete_word(3)</a> man page.
+
+     In brief, the callback function is responsible  for  looking
+     backwards  in  the  input line, back from the point at which
+     the user pressed TAB, to find the start of  the  word  being
+     completed.  It then must lookup possible completions of this
+     word, and record them  one  by  one  in  the  WordCompletion
+     object  that  is passed to it as an argument, by calling the
+     cpl_add_completion()  function.  If  the  callback  function
+     wishes to provide filename completion in addition to its own
+     specific completions, it has the option  of  itself  calling
+     the  builtin  file-name  completion  callback. This also, is
+     documented in the <a href="cpl_complete_word.html">cpl_complete_word(3)</a> man page.
+
+     Note that if you would  like  gl_get_line()  to  return  the
+     current  input  line  when  a  successful completion is been
+     made,   you    can    arrange    this    when    you    call
+     cpl_add_completion(),  by  making  the last character of the
+     continuation suffix a newline character. If you do this, the
+     input  line  will  be  updated  to  display  the completion,
+     together with any contiuation suffix up to the newline char-
+     acter, then gl_get_line() will return this input line.
+
+
+</pre><h2>FILENAME EXPANSION</h2><pre>
+     With  the  default  key  bindings,   pressing   ^X*   causes
+     gl_get_line()  to expand the filename that precedes the cur-
+     sor,  replacing  ~/  and   ~user/   expressions   with   the
+     corresponding   home   directories,  and  replacing  $envvar
+     expressions with the  value  of  the  specified  environment
+     variable,  then if there are any wildcards, replacing the so
+     far expanded filename with a  space-separated  list  of  the
+     files which match the wild cards.
+
+     The   expansion   binding   is   implemented    using    the
+     ef_expand_file()  function.   See  the <a href="ef_expand_file.html">ef_expand_file(3)</a> man
+     page for more details.
+
+
+</pre><h2>RECALLING PREVIOUSLY TYPED LINES</h2><pre>
+     Every time that a new line is entered by  the  user,  it  is
+     appended  to  a  list  of  historical input lines maintained
+     within the GetLine resource object. You can traverse up  and
+     down  this  list  using the up and down arrow keys. Alterna-
+     tively, you can do the same with the ^P, and ^N keys, and in
+     vi  command mode you can alternatively use the k and j char-
+     acters. Thus pressing up-arrow once,  replaces  the  current
+     input  line  with  the previously entered line. Pressing up-
+     arrow again, replaces this with the line  that  was  entered
+     before it, etc.. Having gone back one or more lines into the
+     history list, one can return  to  newer  lines  by  pressing
+     down-arrow  one  or  more  times.  If you do this sufficient
+     times, you will return to the original line  that  you  were
+     entering when you first hit up-arrow.
+
+     Note that in vi mode, all of the  history  recall  functions
+     switch the library into command mode.
+
+     In emacs mode the M-p and M-n keys work just like the ^P and
+     ^N  keys,  except  that  they  skip all but those historical
+     lines which share the prefix that precedes the cursor. In vi
+     command  mode  the upper case K and J characters do the same
+     thing, except that the string that they search for  includes
+     the character under the cursor as well as what precedes it.
+
+     Thus for example, suppose that you were in emacs  mode,  and
+     you  had  just entered the following list of commands in the
+     order shown:
+
+       ls ~/tecla/
+       cd ~/tecla
+       ls -l getline.c
+       emacs ~/tecla/getline.c
+
+     If you next typed:
+
+       ls
+
+     and then hit M-p, then rather than returning the  previously
+     typed   emacs   line,   which   doesn't   start  with  "ls",
+     gl_get_line() would  recall  the  "ls  -l  getline.c"  line.
+     Pressing M-p again would recall the "ls ~/tecla/" line.
+
+
+</pre><h2>HISTORY FILES</h2><pre>
+     To save the contents of the history buffer  before  quitting
+     your  application,  and  subsequently  restore them when you
+     next start the application, the following functions are pro-
+     vided.
+
+
+      int gl_save_history(GetLine *gl, const char *filename,
+                          const char *comment, int max_lines);
+      int gl_load_history(GetLine *gl, const char *filename,
+                          const char *comment);
+
+
+     The filename argument specifies the name to give the history
+     file  when  saving, or the name of an existing history file,
+     when loading. This may contain home-directory  and  environ-
+     ment  variable  expressions,  such  as "~/.myapp_history" or
+     "$HOME/.myapp_history".
+     Along with each history line, extra  information  about  it,
+     such  as when it was entered by the user, and what its nest-
+     ing level is, is recorded as a comment preceding the line in
+     the  history file. Writing this as a comment allows the his-
+     tory file to double as a command file, just in case you wish
+     to  replay  a whole session using it. Since comment prefixes
+     differ in different languages, the comment argument is  pro-
+     vided  for  specifying  the  comment prefix. For example, if
+     your application were a  unix  shell,  such  as  the  bourne
+     shell,  you  would specify "#" here. Whatever you choose for
+     the comment character, you must specify the same  prefix  to
+     gl_load_history()    that   you   used   when   you   called
+     gl_save_history() to write the history file.
+
+     The max_lines must be either -1 to specify that all lines in
+     the history list be saved, or a positive number specifying a
+     ceiling on how many of  the  most  recent  lines  should  be
+     saved.
+
+     Both fuctions return non-zero on  error,  after  writing  an
+     error  message  to  stderr. Note that gl_load_history() does
+     not consider the non-existence of a file to be an error.
+
+
+</pre><h2>MULTIPLE HISTORY LISTS</h2><pre>
+     If your application uses a single GetLine object for  enter-
+     ing  many  different  types  of  input  lines,  you may wish
+     gl_get_line() to distinguish the different types of lines in
+     the  history  list,  and  only  recall  lines that match the
+     current  type  of  line.  To   support   this   requirement,
+     gl_get_line() marks lines being recorded in the history list
+     with an integer identifier chosen by the application.   Ini-
+     tially  this identifier is set to 0 by new_GetLine(), but it
+     can be changed subsequently by calling gl_group_history().
+
+
+       int gl_group_history(GetLine *gl, unsigned id);
+
+
+     The integer identifier id can be any number  chosen  by  the
+     application,    but    note   that   gl_save_history()   and
+     gl_load_history() preserve the association between  identif-
+     iers and historical input lines between program invokations,
+     so you should choose fixed  identifiers  for  the  different
+     types of input line used by your application.
+
+     Whenever gl_get_line() appends a new input line to the  his-
+     tory  list,  the current history identifier is recorded with
+     it, and when it is asked to recall a historical input  line,
+     it only recalls lines that are marked with the current iden-
+     tifier.
+
+</pre><h2>DISPLAYING HISTORY</h2><pre>
+     The   history   list   can   be   displayed    by    calling
+     gl_show_history().
+
+
+       int gl_show_history(GetLine *gl, FILE *fp,
+                           const char *fmt,
+                           int all_groups,
+                           int max_lines);
+
+
+     This displays the current contents of the  history  list  to
+     the  stdio  output  stream  fp. If the max_lines argument is
+     greater than or equal to zero, then no more than this number
+     of   the  most  recent  lines  will  be  displayed.  If  the
+     all_groups argument is  non-zero,  lines  from  all  history
+     groups  are displayed. Otherwise just those of the currently
+     selected history group  are  displayed.  The  format  string
+     argument,  fmt,  determines  how the line is displayed. This
+     can contain arbitrary characters which are written verbatim,
+     interleaved with any of the following format directives:
+
+       %D  -  The date on which the line was originally
+              entered, formatted like 2001-11-20.
+       %T  -  The time of day when the line was entered,
+              formatted like 23:59:59.
+       %N  -  The sequential entry number of the line in
+              the history buffer.
+       %G  -  The number of the history group which the
+              line belongs to.
+       %%  -  A literal % character.
+       %H  -  The history line itself.
+
+     Thus a format string like "%D %T  %H0 would output something
+     like:
+
+       2001-11-20 10:23:34  Hello world
+
+     Note the inclusion of an explicit newline character  in  the
+     format string.
+
+
+</pre><h2>LOOKING UP HISTORY</h2><pre>
+     The gl_lookup_history() function allows the calling applica-
+     tion to look up lines in the history list.
+
+
+       typedef struct {
+         const char *line;    /* The requested historical */
+                              /*  line. */
+         unsigned group;      /* The history group to which */
+                              /*  the line belongs. */
+         time_t timestamp;    /* The date and time at which */
+                              /*  the line was originally */
+                              /*  entered. */
+       } GlHistoryLine;
+
+       int gl_lookup_history(GetLine *gl, unsigned long id,
+                             GlHistoryLine *hline);
+
+
+     The id argument indicates which line to look up,  where  the
+     first  line  that  was  entered  in  the  history list after
+     new_GetLine() was called, is denoted by 0, and  subsequently
+     entered  lines are denoted with successively higher numbers.
+     Note that the range of lines currently preserved in the his-
+     tory    list    can    be    queried    by    calling    the
+     gl_range_of_history()  function,  described  later.  If  the
+     requested  line  is  in the history list, the details of the
+     line are recorded in the variable pointed to  by  the  hline
+     argument,  and  1  is returned. Otherwise 0 is returned, and
+     the variable pointed to by hline is left unchanged.
+
+     Beware that the string returned in hline-&gt;line  is  part  of
+     the  history  buffer,  so  it  must  not  be modified by the
+     caller, and will be recycled on the next call to  any  func-
+     tion  that  takes  gl  as its argument. Therefore you should
+     make a private copy of this string if you need  to  keep  it
+     around.
+
+
+</pre><h2>MISCELLANEOUS HISTORY CONFIGURATION</h2><pre>
+     If you wish to change the size of the  history  buffer  that
+     was  originally  specified in the call to new_GetLine(), you
+     can do so with the gl_resize_history() function.
+
+
+       int gl_resize_history(GetLine *gl, size_t histlen);
+
+
+     The histlen argument specifies the new size in bytes, and if
+     you specify this as 0, the buffer will be deleted.
+
+     As mentioned in the discussion of new_GetLine(), the  number
+     of  lines  that can be stored in the history buffer, depends
+     on the lengths of the individual lines. For example, a  1000
+     byte  buffer  could equally store 10 lines of average length
+     100 bytes, or 2 lines of average length 50  bytes.  Although
+     the  buffer  is  never  expanded when new lines are added, a
+     list of pointers into the  buffer  does  get  expanded  when
+     needed to accomodate the number of lines currently stored in
+     the buffer. To place an upper limit on the number  of  lines
+     in  the  buffer,  and thus a ceiling on the amount of memory
+     used in this  list,  you  can  call  the  gl_limit_history()
+     function.
+
+
+       void gl_limit_history(GetLine *gl, int max_lines);
+
+
+     The max_lines should either  be  a  positive  number  &gt;=  0,
+     specifying  an  upper  limit  on  the number of lines in the
+     buffer, or be -1 to cancel any previously  specified  limit.
+     When  a limit is in effect, only the max_lines most recently
+     appended lines are kept in the buffer. Older lines are  dis-
+     carded.
+
+     To  discard  lines  from  the  history   buffer,   use   the
+     gl_clear_history() function.
+
+       void gl_clear_history(GetLine *gl, int all_groups);
+
+     The all_groups argument tells the function whether to delete
+     just  the  lines  associated  with the current history group
+     (see gl_group_history()), or all  historical  lines  in  the
+     buffer.
+
+     The gl_toggle_history() function allows you to  toggle  his-
+     tory  on  and off without losing the current contents of the
+     history list.
+
+
+       void gl_toggle_history(GetLine *gl, int enable);
+
+
+     Setting the enable argument  to  0  turns  off  the  history
+     mechanism,  and  setting it to 1 turns it back on. When his-
+     tory is turned off, no new lines will be added to  the  his-
+     tory  list,  and  history  lookup  key-bindings  will act as
+     though there is nothing in the history buffer.
+
+
+</pre><h2>QUERYING HISTORY INFORMATION</h2><pre>
+     The configured state of the history list can be queried with
+     the gl_history_state() function.
+
+
+       typedef struct {
+         int enabled;     /* True if history is enabled */
+         unsigned group;  /* The current history group */
+         int max_lines;   /* The current upper limit on the */
+                          /*  number of lines in the history */
+                          /*  list, or -1 if unlimited. */
+       } GlHistoryState;
+
+       void gl_state_of_history(GetLine *gl,
+                                GlHistoryState *state);
+
+     On return, the status information is recorded in  the  vari-
+     able pointed to by the state argument.
+
+     The gl_range_of_history() function returns  the  number  and
+     range of lines in the history list.
+
+
+     typedef struct {
+       unsigned long oldest;  /* The sequential entry number */
+                              /*  of the oldest line in the */
+                              /*  history list. */
+       unsigned long newest;  /* The sequential entry number */
+                              /*  of the newest line in the */
+                              /*  history list. */
+       int nlines;            /* The number of lines in the */
+                              /*  history list. */
+     } GlHistoryRange;
+
+     void gl_range_of_history(GetLine *gl, GlHistoryRange *range);
+
+     The return values are recorded in the variable pointed to by
+     the  range  argument. If the nlines member of this structure
+     is greater than zero, then the  oldest  and  newest  members
+     report    the    range   of   lines   in   the   list,   and
+     newest=oldest+nlines-1.  Otherwise they are both zero.
+
+     The gl_size_of_history() function returns the total size  of
+     the  history  buffer  and  the  amount of the buffer that is
+     currently occupied.
+
+       typedef struct {
+         size_t size;      /* The size of the history buffer */
+                           /*  (bytes). */
+         size_t used;      /* The number of bytes of the */
+                           /*  history buffer that are */
+                           /*  currently occupied. */
+       } GlHistorySize;
+
+       void gl_size_of_history(GetLine *gl, GlHistorySize *size);
+
+     On return, the size information is recorded in the  variable
+     pointed to by the size argument.
+
+
+</pre><h2>CHANGING TERMINALS</h2><pre>
+     The new_GetLine() constructor function assumes that input is
+     to  be  read  from  stdin, and output written to stdout. The
+     following function allows you to switch to  different  input
+     and output streams.
+
+       int gl_change_terminal(GetLine *gl, FILE *input_fp,
+                              FILE *output_fp, const char *term);
+
+     The  gl  argument  is  the  object  that  was  returned   by
+     new_GetLine().   The  input_fp argument specifies the stream
+     to read from, and output_fp specifies the stream to be writ-
+     ten  to.  Only  if  both  of these refer to a terminal, will
+     interactive   terminal   input   be   enabled.     Otherwise
+     gl_get_line()  will  simply  call  fgets()  to  read command
+     input. If both streams refer to a terminal, then  they  must
+     refer  to  the  same terminal, and the type of this terminal
+     must be specified via the term argument. The  value  of  the
+     term argument is looked up in the terminal information data-
+     base (terminfo or termcap), in order to determine which spe-
+     cial control sequences are needed to control various aspects
+     of the  terminal.  new_GetLine()  for  example,  passes  the
+     return  value  of getenv("TERM") in this argument. Note that
+     if one or both of input_fp and output_fp don't  refer  to  a
+     terminal,  then it is legal to pass NULL instead of a termi-
+     nal type.
+
+     Note  that  if  you  want  to  pass  file   descriptors   to
+     gl_change_terminal(),  you  can  do  this  by creating stdio
+     stream wrappers using the POSIX fdopen() function.

+     While gl_get_line() is waiting for keyboard input  from  the
+     user, you can ask it to also watch for activity on arbitrary
+     file descriptors, such as network sockets,  pipes  etc,  and
+     have  it  call  functions  of your choosing when activity is
+     seen. This works on any system that has the select()  system
+     call, which is most, if not all flavors of unix. Registering
+     a file descriptor to be watched  by  gl_get_line()  involves
+     calling the gl_watch_fd() function.
+
+
+       int gl_watch_fd(GetLine *gl, int fd, GlFdEvent event,
+                       GlFdEventFn *callback, void *data);
+
+
+     If this returns non-zero, then it  means  that  either  your
+     arguments are invalid, or that this facility isn't supported
+     on the host system.
+
+     The fd argument is the file descriptor to  be  watched.  The
+     event  argument  specifies  what  type  of  activity  is  of
+     interest, chosen from the following enumerated values:
+
+
+       GLFD_READ   -  Watch for the arrival of data to be read.
+       GLFD_WRITE  -  Watch for the ability to write to the file
+                      descriptor without blocking.
+       GLFD_URGENT -  Watch for the arrival of urgent
+                      out-of-band data on the file descriptor.
+
+
+     The callback argument is  the  function  to  call  when  the
+     selected  activity  is  seen.  It should be defined with the
+     following macro, which is defined in libtecla.h.
+
+
+       #define GL_FD_EVENT_FN(fn) GlFdStatus (fn)(GetLine *gl, \
+                                           void *data, int fd, \
+                                           GlFdEvent event)
+
+     The data argument of the gl_watch_fd() function is passed to
+     the callback function for its own use, and can point to any-
+     thing you like, including NULL. The file descriptor and  the
+     event argument are also passed to the callback function, and
+     this potentially allows the same  callback  function  to  be
+     registered  to  more than one type of event and/or more than
+     one file descriptor. The return value of the callback  func-
+     tion should be one of the following values.
+
+
+       GLFD_ABORT    -  Tell gl_get_line() to abort with an
+                        error (errno won't be set, so set it
+                        appropriately yourself if you need it).
+       GLFD_REFRESH  -  Redraw the input line then continue
+                        waiting for input. Return this if
+                        your callback wrote to the terminal.
+       GLFD_CONTINUE -  Continue to wait for input, without
+                        redrawing the line.
+
+     Note that before calling the callback, gl_get_line()  blocks
+     most  signals, and leaves its own signal handlers installed,
+     so if you need to catch a particular signal you will need to
+     both  temporarily  install  your  own  signal  handler,  and
+     unblock the signal. Be sure to re-block the  signal  (if  it
+     was  originally  blocked)  and reinstate the original signal
+     handler, if any, before returning.
+
+     Your callback shouldn't try to read from the terminal, which
+     is  left  in  raw mode as far as input is concerned. You can
+     however write to the terminal as usual, since features  like
+     conversion  of  newline  to carriage-return/linefeed are re-
+     enabled while the callback  is  running.  If  your  callback
+     function  does  write  to  the terminal, be sure to output a
+     newline  first,  and  when  your  callback   returns,   tell
+     gl_get_line()  that  the  input line needs to be redrawn, by
+     returning the GLFD_REFRESH status code.
+
+     To remove a callback function that you previously registered
+     for   a   given  file  descriptor  and  event,  simply  call
+     gl_watch_fd() with the same file descriptor and event  argu-
+     ments,  but with a callback argument of 0. The data argument
+     is ignored in this case.
+
+
+</pre><h2>SIGNAL HANDLING DEFAULTS</h2><pre>
+     By default, the gl_get_line() function intercepts  a  number
+     of signals. This is particularly important for signals which
+     would by default terminate the process, since  the  terminal
+     needs  to be restored to a usable state before this happens.
+     In this section, the signals that are  trapped  by  default,
+     and how gl_get_line() responds to them, is described. Chang-
+     ing these defaults is the topic of the following section.
+
+     When  the  following   subset   of   signals   are   caught,
+     gl_get_line()  first restores the terminal settings and sig-
+     nal handling to  how  they  were  before  gl_get_line()  was
+     called,   resends   the   signal,   to   allow  the  calling
+     application's signal handlers to handle it, then if the pro-
+     cess still exists, gl_get_line() returns NULL and sets errno
+     as specified below.
+
+
+      SIGINT  -  This signal is generated both by the keyboard
+                 interrupt key (usually ^C), and the keyboard
+                 break key.
+
+                 errno=EINTR
+
+      SIGHUP  -  This signal is generated when the controlling
+                 terminal exits.
+
+                 errno=ENOTTY
+
+      SIGPIPE -  This signal is generated when a program attempts
+                 to write to a pipe who's remote end isn't being
+                 read by any process. This can happen for example
+                 if you have called gl_change_terminal() to
+                 redirect output to a pipe hidden under a pseudo
+                 terminal.
+
+                 errno=EPIPE
+
+      SIGQUIT -  This signal is generated by the keyboard quit
+                 key (usually ^\).
+
+                 errno=EINTR
+
+      SIGABRT -  This signal is generated by the standard C,
+                 abort() function. By default it both
+                 terminates the process and generates a core
+                 dump.
+
+                 errno=EINTR
+
+      SIGTERM -  This is the default signal that the UN*X
+                 kill command sends to processes.
+
+                 errno=EINTR
+
+     Note that in the case of all of  the  above  signals,  POSIX
+     mandates that by default the process is terminated, with the
+     addition of a core dump in the case of the  SIGQUIT  signal.
+     In  other words, if the calling application doesn't override
+     the default handler by supplying  its  own  signal  handler,
+     receipt  of  the  corresponding  signal  will  terminate the
+     application before gl_get_line() returns.
+
+     If gl_get_line() aborts with errno set  to  EINTR,  you  can
+     find out what signal caused it to abort, by calling the fol-
+     lowing function.
+
+       int gl_last_signal(const GetLine *gl);
+
+     This returns the numeric code (eg. SIGINT) of the last  sig-
+     nal  that  was  received  during  the  most  recent  call to
+     gl_get_line(), or -1 if no signals were received.
+
+     On systems that support it, when a SIGWINCH (window  change)
+     signal  is  received,  gl_get_line() queries the terminal to
+     find out its new size, redraws the  current  input  line  to
+     accomodate  the  new  size, then returns to waiting for key-
+     board input from the user. Unlike other signals, this signal
+     isn't resent to the application.
+
+     Finally, the following signals cause gl_get_line() to  first
+     restore  the  terminal  and signal environment to that which
+     prevailed before gl_get_line() was called, then  resend  the
+     signal to the application. If the process still exists after
+     the signal has been delivered, then gl_get_line()  then  re-
+     establishes  its  own signal handlers, switches the terminal
+     back to raw mode, redisplays the input line, and  goes  back
+     to awaiting terminal input from the user.
+
+      SIGCONT    -  This signal is generated when a suspended
+                    process is resumed.
+
+      SIGPWR     -  This signal is generated when a power failure
+                    occurs (presumably when the system is on a
+                    UPS).
+
+      SIGALRM    -  This signal is generated when a timer
+                    expires.
+      SIGUSR1    -  An application specific signal.
+
+      SIGUSR2    -  Another application specific signal.
+
+      SIGVTALRM  -  This signal is generated when a virtual
+                    timer expires (see man setitimer(2)).
+
+      SIGXCPU    -  This signal is generated when a process
+                    exceeds its soft CPU time limit.
+
+      SIGTSTP    -  This signal is generated by the terminal
+                    suspend key, which is usually ^Z, or the
+                    delayed terminal suspend key, which is
+                    usually ^Y.
+
+      SIGTTIN    -  This signal is generated if the program
+                    attempts to read from the terminal while the
+                    program is running in the background.
+
+      SIGTTOU    -  This signal is generated if the program
+                    attempts to write to the terminal while the
+                    program is running in the background.
+
+
+     Obviously not all of the above signals are supported on  all
+     systems,  so  code to support them is conditionally compiled
+     into the tecla library.
+
+     Note that if SIGKILL, which by definition can't  be  caught,
+     or  any of the hardware generated exception signals, such as
+     SIGSEGV, SIGBUS and SIGFPE, are received and unhandled while
+     gl_get_line() has the terminal in raw mode, the program will
+     be terminated without the terminal having been restored to a
+     usable  state. In practice, job-control shells usually reset
+     the terminal settings when a process relinquishes  the  con-
+     trolling  terminal,  so  this  is  only a problem with older
+     shells.
+
+
+</pre><h2>CUSTOMIZED SIGNAL HANDLING</h2><pre>
+     The previous section listed the signals  that  gl_get_line()
+     traps  by  default,  and  described how it responds to them.
+     This section describes how to both add  and  remove  signals
+     from  the  list  of  trapped signals, and how to specify how
+     gl_get_line() should respond to a given signal.
+
+     If you don't need gl_get_line() to do anything  in  response
+     to  a  signal  that  it  normally  traps,  you  can  tell to
+     gl_get_line()   to   ignore   that   signal    by    calling
+     gl_ignore_signal().
+
+       int gl_ignore_signal(GetLine *gl, int signo);
+     The signo argument is the number of the signal (eg.  SIGINT)
+     that you want to have ignored. If the specified signal isn't
+     currently one of those being  trapped,  this  function  does
+     nothing.
+
+     The gl_trap_signal() function allows you to either add a new
+     signal  to  the list that gl_get_line() traps, or modify how
+     it responds to a signal that it already traps.
+
+       int gl_trap_signal(GetLine *gl, int signo, unsigned flags,
+                          GlAfterSignal after, int errno_value);
+
+     The signo argument is the number of the signal that you wish
+     to  have trapped. The flags argument is a set of flags which
+     determine the environment in which the application's  signal
+     handler  is  invoked, the after argument tells gl_get_line()
+     what to do after the application's signal  handler  returns,
+     and  errno_value tells gl_get_line() what to set errno to if
+     told to abort.
+
+     The flags argument is a bitwise OR of zero or  more  of  the
+     following enumerators:
+
+       GLS_RESTORE_SIG  -  Restore the caller's signal
+                           environment while handling the
+                           signal.
+
+       GLS_RESTORE_TTY  -  Restore the caller's terminal settings
+                           while handling the signal.
+
+       GLS_RESTORE_LINE -  Move the cursor to the start of the
+                           line following the input line before
+                           invoking the application's signal
+                           handler.
+
+       GLS_REDRAW_LINE  -  Redraw the input line when the
+                           application's signal handler returns.
+
+       GLS_UNBLOCK_SIG  -  Normally, if the calling program has
+                           a signal blocked (man sigprocmask),
+                           gl_get_line() does not trap that
+                           signal. This flag tells gl_get_line()
+                           to trap the signal and unblock it for
+                           the duration of the call to
+                           gl_get_line().
+
+       GLS_DONT_FORWARD -  If this flag is included, the signal
+                           will not be forwarded to the signal
+                           handler of the calling program.
+
+     Two commonly useful flag combinations are also enumerated as
+     follows:
+       GLS_RESTORE_ENV   = GLS_RESTORE_SIG | GLS_RESTORE_TTY |
+                           GLS_REDRAW_LINE
+
+       GLS_SUSPEND_INPUT = GLS_RESTORE_ENV | GLS_RESTORE_LINE
+
+
+     If your signal handler, or the default system signal handler
+     for  this  signal, if you haven't overriden it, never either
+     writes to the terminal, nor suspends or terminates the  cal-
+     ling  program, then you can safely set the flags argument to
+     0.
+
+     If your signal handler always writes to the terminal,  reads
+     from  it,  or suspends or terminates the program, you should
+     specify the flags argument as GL_SUSPEND_INPUT, so that:
+
+     1. The cursor doesn't get left in the middle of the input
+        line.
+     2. So that the user can type in input and have it echoed.
+     3. So that you don't need to end each output line with
+        \r\n, instead of just \n.
+
+     The   GL_RESTORE_ENV   combination   is    the    same    as
+     GL_SUSPEND_INPUT,  except  that  it doesn't move the cursor,
+     and if your signal handler doesn't read or write anything to
+     the terminal, the user won't see any visible indication that
+     a signal was caught. This can be useful if you have a signal
+     handler that only occasionally writes to the terminal, where
+     using GL_SUSPEND_LINE would  cause  the  input  line  to  be
+     unnecessarily  duplicated  when  nothing had been written to
+     the terminal.  Such a signal handler, when it does write  to
+     the  terminal,  should  be  sure  to start a new line at the
+     start of its first write,  by  writing  a  new  line  before
+     returning.  If the signal arrives while the user is entering
+     a line that only occupies a signal terminal line, or if  the
+     cursor  is on the last terminal line of a longer input line,
+     this will have the same effect as  GL_SUSPEND_INPUT.  Other-
+     wise  it  will start writing on a line that already contains
+     part of the displayed input line.  This doesn't do any harm,
+     but  it  looks a bit ugly, which is why the GL_SUSPEND_INPUT
+     combination is better if you know that you are always  going
+     to be writting to the terminal.
+
+     The after argument, which determines what gl_get_line() does
+     after  the  application's  signal  handler  returns  (if  it
+     returns), can take any one of the following values:
+
+       GLS_RETURN   - Return the completed input line, just as
+                      though the user had pressed the return
+                      key.
+
+       GLS_ABORT    - Cause gl_get_line() to return NULL.
+       GLS_CONTINUE - Resume command line editing.
+
+     The errno_value argument is intended to be combined with the
+     GLS_ABORT  option,  telling  gl_get_line()  what  to set the
+     standard errno variable to before returning NULL to the cal-
+     ling  program.  It  can  also,  however,  be  used  with the
+     GL_RETURN option, in case you wish to have a way to  distin-
+     guish  between  an  input  line  that  was entered using the
+     return key, and one that was entered by  the  receipt  of  a
+     signal.
+
+
+</pre><h2>THE TERMINAL SIZE</h2><pre>
+     On most systems the combination of the TIOCGWINSZ ioctl  and
+     the  SIGWINCH signal is used to maintain an accurate idea of
+     the terminal size. The terminal size is newly queried  every
+     time  that  gl_get_line()  is called and whenever a SIGWINCH
+     signal is received.
+
+     On the few systems where this mechanism isn't available,  at
+     startup  new_GetLine() first looks for the LINES and COLUMNS
+     environment variables.  If these aren't found, or they  con-
+     tain  unusable  values, then if a terminal information data-
+     base like terminfo or termcap is available, the default size
+     of  the  terminal is looked up in this database. If this too
+     fails to provide the terminal size, a  default  size  of  80
+     columns by 24 lines is used. If this default isn't appropri-
+     ate for your system, gl_terminal_size() can be used to  sup-
+     ply a different fallback.
+
+     The gl_terminal_size() function  allows  you  to  query  the
+     current size of the terminal, and install an alternate fall-
+     back size for cases where the size isn't available.   Beware
+     that  the terminal size won't be available if reading from a
+     pipe or a file, so the default values can be important  even
+     on  systems that do support ways of finding out the terminal
+     size.
+
+       typedef struct {
+         int nline;        /* The terminal has nline lines */
+         int ncolumn;      /* The terminal has ncolumn columns */
+       } GlTerminalSize;
+
+       GlTerminalSize gl_terminal_size(GetLine *gl,
+                                       int def_ncolumn,
+                                       int def_nline);
+
+     This function first updates gl_get_line()'s idea of the ter-
+     minal size, then records its findings in the return value.
+
+     The def_ncolumn and def_nline specify the default number  of
+     terminal columns and lines to use if the terminal size can't
+     be determined.
+
+
+</pre><h2>HIDING WHAT YOU TYPE</h2><pre>
+     When entering sensitive information, such as  passwords,  it
+     is best not to have the text that you are entering echoed on
+     the terminal.  Furthermore, such text should not be recorded
+     in  the  history  list, since somebody finding your terminal
+     unattended  could  then  recall  it,  or  somebody  snooping
+     through  your directories could see it in your history file.
+     With this in mind, the gl_echo_mode() function allows you to
+     toggle  on and off the display and archival of any text that
+     is subsequently entered in calls to gl_get_line().
+
+
+       int gl_echo_mode(GetLine *gl, int enable);
+
+
+     The enable argument specifies whether entered text should be
+     visible  or not. If it is 0, then subsequently entered lines
+     will not be  visible  on  the  terminal,  and  will  not  be
+     recorded  in  the  history list. If it is 1, then subsequent
+     input lines will be displayed as they are entered, and  pro-
+     vided  that  history  hasn't  been  turned off via a call to
+     gl_toggle_history(), then they will also be archived in  the
+     history  list.  Finally,  if the enable argument is -1, then
+     the echoing mode is left  unchanged,  which  allows  you  to
+     non-destructively  query  the current setting via the return
+     value. In all cases, the return value of the function  is  0
+     if  echoing was disabled before the function was called, and
+     1 if it was enabled.
+
+     When echoing is turned off, note that although  tab  comple-
+     tion will invisibly complete your prefix as far as possible,
+     ambiguous completions will not be displayed.
+
+
+</pre><h2>CALLBACK FUNCTION FACILITIES</h2><pre>
+     Unless otherwise stated, callback  functions,  such  as  tab
+     completion callbacks and event callbacks should not call any
+     functions in this module. The following functions,  however,
+     are designed specifically to be used by callback functions.
+
+     Calling the gl_replace_prompt()  function  from  a  callback
+     tells  gl_get_line()  to display a different prompt when the
+     callback  returns.  It  has  no  effect   if   called   when
+     gl_get_line() is not being called.
+
+       void gl_replace_prompt(GetLine *gl, const char *prompt);
+
+
+
+</pre><h2>INTERNATIONAL CHARACTER SETS</h2><pre>
+     Since libtecla version 1.4.0, gl_get_line() has  been  8-bit
+     clean.  This means that all 8-bit characters that are print-
+     able in the user's current locale are now displayed verbatim
+     and  included in the returned input line.  Assuming that the
+     calling program correctly contains a call like  the  follow-
+     ing,
+
+       setlocale(LC_CTYPE, "");
+
+     then the current locale is determined by the  first  of  the
+     environment  variables  LC_CTYPE,  LC_ALL, and LANG, that is
+     found to contain a valid locale name. If none of these vari-
+     ables  are  defined,  or the program neglects to call setlo-
+     cale, then the default C locale is used, which is  US  7-bit
+     ASCII.  On  most  unix-like platforms, you can get a list of
+     valid locales by typing the command:
+
+       locale -a
+
+     at the shell prompt.
+
+
+</pre><h2>  Meta keys and locales</h2><pre>
+     Beware that in most locales other than the default C locale,
+     meta  characters  become  printable,  and  they  are then no
+     longer considered to match  M-c  style  key  bindings.  This
+     allows  international characters to be entered with the com-
+     pose key without unexpectedly triggering meta key  bindings.
+     You can still invoke meta bindings, since there are actually
+     two ways to do this. For example the binding M-c can also be
+     invoked  by pressing the escape key momentarily, then press-
+     ing the c key, and this  will  work  regardless  of  locale.
+     Moreover,  many  modern  terminal emulators, such as gnome's
+     gnome-terminal's and KDE's konsole terminals,  already  gen-
+     erate  escape  pairs  like  this  when you use the meta key,
+     rather than a real meta character, and other emulators  usu-
+     ally  have  a  way to request this behavior, so you can con-
+     tinue to use the meta key on most systems.
+
+     For example, although xterm terminal emulators generate real
+     8-bit  meta characters by default when you use the meta key,
+     they can be configured to output the equivalent escape  pair
+     by  setting their EightBitInput X resource to False. You can
+     either do this by placing a line like the following in  your
+     ~/.Xdefaults file,
+
+       XTerm*EightBitInput: False
+
+     or by starting an xterm with an -xrm '*EightBitInput: False'
+     command-line  argument.  In recent versions of xterm you can
+     toggle this feature on and off with the "Meta Sends  Escape"
+     option in the menu that is displayed when you press the left
+     mouse button and the control key within an xterm window.  In
+     CDE,  dtterms  can  be  similarly coerced to generate escape
+     pairs  in  place  of  meta  characters,   by   setting   the
+     Dtterm*KshMode resource to True.
+
+
+</pre><h2>  Entering international characters</h2><pre>
+     If you don't have a  keyboard  that  generates  all  of  the
+     international  characters  that you need, there is usually a
+     compose key that will allow you to enter special characters,
+     or  a  way  to  create  one. For example, under X windows on
+     unix-like systems, if your keyboard doesn't have  a  compose
+     key, you can designate a redundant key to serve this purpose
+     with the xmodmap command. For example, on many PC  keyboards
+     there is a microsoft-windows key, which is otherwise useless
+     under Linux. On my PC the xev program reports that  pressing
+     this  key  generates keycode 115, so to turn this key into a
+     compose key, I do the following:
+
+       xmodmap -e 'keycode 115 = Multi_key'
+
+     I can then enter an i with a umlaut over it by  typing  this
+     key, followed by ", followed by i.
+
+
+</pre><h2>THREAD SAFETY</h2><pre>
+     In a multi-threaded program, you should use the libtecla_r.a
+     version of the library. This uses reentrant versions of sys-
+     tem functions, where available. Unfortunately  neither  ter-
+     minfo  nor  termcap  were  designed  to be reentrant, so you
+     can't safely use the functions of the getline module in mul-
+     tiple  threads  (you can use the separate file-expansion and
+     word-completion  modules  in  multiple  threads,   see   the
+     corresponding man pages for details). However due to the use
+     of POSIX reentrant functions for looking up home directories
+     etc, it is safe to use this module from a single thread of a
+     multi-threaded program, provided  that  your  other  threads
+     don't use any termcap or terminfo functions.

+<HEAD><TITLE>The tecla command-line editing library.</TITLE></HEAD>
+<BODY bgcolor=add8e6>
+<H1>The Tecla command-line editing library.</H1>
+
+The tecla library provides UNIX and LINUX programs with interactive
+command line editing facilities, similar to those of the UNIX tcsh
+shell. In addition to simple command-line editing, it supports recall
+of previously entered command lines, TAB completion of file names or
+other tokens, and in-line wild-card expansion of filenames.  The
+internal functions which perform file-name completion and wild-card
+expansion are also available externally for optional use by programs.
+<P>
+In addition, the library includes a path-searching module.  This
+allows an application to provide completion and lookup of files
+located in UNIX style paths. Although not built into the line editor
+by default, it can easily be called from custom tab-completion
+callback functions. This was originally conceived for completing the
+names of executables and providing a way to look up their locations in
+the user's PATH environment variable, but it can easily be asked to
+look up and complete other types of files in any list of directories.
+
+<P>
+Note that special care has been taken to allow the use of this library
+in threaded programs. The option to enable this is discussed in the
+Makefile, and specific discussions of thread safety are presented in
+the included man pages.
+<P>
+The current version is version 1.4.1. This may be obtained from:

+  Mac OS X
+  Cygwin (running under Windows)
+  QNX
+</pre>
+
+There haven't been many reports concerning the POSIX reentrant
+version, so the absence of any of the above from the following list of
+systems on which the reentrant version is known to work, shouldn't be
+taken as an indication that the reentrant version doesn't work.
+
+<pre>
+  Sun Solaris 2.5,2.6,7,8, with any of gcc, Sun C, or g++.

+  Alpha OSF1, cc
+</pre>
+
+The only system that is known to have issues with the reentrant
+version of the library is SCO UnixWare 7.1.1. The problem is in the
+system provided signal.h, which breaks when POSIX_C_SOURCE is
+defined. It has been reported that this can be fixed by editing
+signal.h.

+</pre><h2>NAME</h2><pre>
+     libtecla - An interactive command-line input library.
+
+</pre><h2>SYNOPSIS</h2><pre>
+     gcc ... -ltecla -lcurses
+
+
+</pre><h2>DESCRIPTION</h2><pre>
+     The tecla library provides programs with interactive command
+     line  editing  facilities, similar to those of the unix tcsh
+     shell. In addition to simple command-line editing,  it  sup-
+     ports  recall  of previously entered command lines, TAB com-
+     pletion of file names or other tokens, and in-line wild-card
+     expansion of filenames. The internal functions which perform
+     file-name completion and wild-card expansion are also avail-
+     able externally for optional use by the calling program.
+
+     The various parts of the library are documented in the  fol-
+     lowing man pages:
+
+       <a href="gl_get_line.html">gl_get_line(3)</a>        -  The interactive line-input module.
+       <a href="cpl_complete_word.html">cpl_complete_word(3)</a>  -  The word completion module.
+       <a href="ef_expand_file.html">ef_expand_file(3)</a>     -  The filename expansion module.
+       <a href="pca_lookup_file.html">pca_lookup_file(3)</a>    -  A directory-list based filename
+                                lookup and completion module.
+
+     In addition there is one  optional  application  distributed
+     with the library:
+
+       <a href="enhance.html">enhance(3)</a>            -  Add command-line editing to third
+                                party applications.
+
+
+</pre><h2>THREAD SAFETY</h2><pre>
+     If the library is compiled  with  -D_POSIX_C_SOURCE=199506L,
+     reentrant  versions  of  as  many  functions as possible are
+     used. This  includes  using  getpwuid_r()  and  getpwnam_r()
+     instead  of  getpwuid()  and  getpwnam() when looking up the
+     home directories of specific users in the password file (for
+     ~user/  expansion), and readdir_r() instead of readdir() for
+     reading directory entries when  doing  filename  completion.
+     The  reentrant  version  of  the  library  is usually called
+     libtecla_r.a instead of libtecla.a, so if only the latter is
+     available,  it  probably  isn't  the correct version to link
+     with threaded programs.
+
+     Reentrant functions for iterating through the password  file
+     aren't  available,  so  when  the  library is compiled to be
+     reentrant, TAB completion of incomplete usernames in  ~user-
+     name/  expressions  is disabled. This doesn't disable expan-
+     sion of complete ~username expressions, which  can  be  done
+     reentrantly,  or  expansion  of  the parts of filenames that
+     follow them, so this doesn't remove much functionality.
+
+     The terminfo functions setupterm(),  tigetstr(),  tigetnum()
+     and  tputs()  also  aren't  reentrant, but very few programs
+     will want to  interact  with  multiple  terminals,  so  this
+     shouldn't  prevent  this library from being used in threaded
+     programs.
+
+
+</pre><h2>LIBRARY VERSION NUMBER</h2><pre>
+     The version number of the library can be queried  using  the
+     following function.
+
+      void libtecla_version(int *major, int *minor, int *micro);
+
+
+     On return, this function records the three components of the
+     libtecla  version number in *major, *minor, *micro. The for-
+     mal meaning of the three components is as follows.
+
+
+      major - Incrementing this number implies that a change has
+              been made to the library's public interface, which
+              makes it binary incompatible  with programs that
+              were linked with previous shared versions of the
+              tecla library.
+
+      minor - This number is incremented by one whenever
+              additional functionality, such as new functions or
+              modules, are added to the library.
+
+      micro - This is incremented whenever modifications to the
+              library are made which make no changes to the
+              public interface, but which fix bugs and/or improve
+              the behind-the-scenes implementation.
+
+
+
+</pre><h2>TRIVIA</h2><pre>
+     In Spanish, a "tecla" is the key of a keyboard.  Since  this
+     library  centers  on  keyboard input, and given that I wrote
+     much of the library while working in Chile, this seemed like
+     a suitable name.

+
+
+
+</pre><h2>DESCRIPTION</h2><pre>
+     The PathCache object is part of the tecla library  (see  the
+     <a href="libtecla.html">libtecla(3)</a> man page).
+
+     PathCache objects allow an application to search  for  files
+     in any colon separated list of directories, such as the unix
+     execution  PATH  environment  variable.  Files  in  absolute
+     directories  are cached in a PathCache object, whereas rela-
+     tive directories are scanned as needed.  Using  a  PathCache
+     object,  you  can  look  up  the  full  pathname of a simple
+     filename, or you can obtain a list of the  possible  comple-
+     tions  of  a  given filename prefix. By default all files in
+     the list of directories are targets for lookup  and  comple-
+     tion, but a versatile mechanism is provided for only select-
+     ing specific types of files. The obvious application of this
+     facility  is to provide Tab-completion and lookup of execut-
+     able commands in the unix  PATH,  so  an  optional  callback
+     which rejects all but executable files, is provided.
+
+
+</pre><h2>AN EXAMPLE</h2><pre>
+     Under UNIX, the  following  example  program  looks  up  and
+     displays  the full pathnames of each of the command names on
+     the command line.
+       #include &lt;stdio.h&gt;
+       #include &lt;stdlib.h&gt;
+       #include &lt;libtecla.h&gt;
+
+       int main(int argc, char *argv[])
+       {
+         int i;
+       /*
+        * Create a cache for executable files.
+        */
+         PathCache *pc = new_PathCache();
+         if(!pc)
+           exit(1);
+       /*
+        * Scan the user's PATH for executables.
+        */
+         if(pca_scan_path(pc, getenv("PATH"))) {
+           fprintf(stderr, "%s\n", pca_last_error(pc));
+           exit(1);
+         }
+       /*
+        * Arrange to only report executable files.
+        */
+        pca_set_check_fn(pc, cpl_check_exe, NULL);
+       /*
+        * Lookup and display the full pathname of each of the
+        * commands listed on the command line.
+        */
+         for(i=1; i&lt;argc; i++) {
+           char *cmd = pca_lookup_file(pc, argv[i], -1, 0);
+           printf("The full pathname of '%s' is %s\n", argv[i],
+                  cmd ? cmd : "unknown");
+         }
+         pc = del_PathCache(pc);  /* Clean up */
+         return 0;
+       }
+
+     The following is an example of what this does on  my  laptop
+     under linux:
+
+       $ ./example less more blob
+       The full pathname of 'less' is /usr/bin/less
+       The full pathname of 'more' is /bin/more
+       The full pathname of 'blob' is unknown
+       $
+
+
+</pre><h2>FUNCTION DESCRIPTIONS</h2><pre>
+     In order to use the facilities  of  this  module,  you  must
+     first   allocate   a   PathCache   object   by  calling  the
+     new_PathCache() constructor function.
+
+       PathCache *new_PathCache(void)
+
+     This function creates the  resources  needed  to  cache  and
+     lookup  files  in  a list of directories. It returns NULL on
+     error.
+
+
+</pre><h2>POPULATING THE CACHE</h2><pre>
+     Once you have created a cache, it needs to be populated with
+     files.  To do this, call the pca_scan_path() function.
+
+       int pca_scan_path(PathCache *pc, const char *path);
+
+     Whenever this function is called, it  discards  the  current
+     contents  of  the  cache, then scans the list of directories
+     specified in its path argument for files. The path  argument
+     must be a string containing a colon-separated list of direc-
+     tories, such as "/usr/bin:/home/mcs/bin:.". This can include
+     directories   specified   by   absolute  pathnames  such  as
+     "/usr/bin", as well as sub-directories specified by relative
+     pathnames such as "." or "bin". Files in the absolute direc-
+     tories are immediately cached  in  the  specified  PathCache
+     object,  whereas sub-directories, whose identities obviously
+     change whenever the current working  directory  is  changed,
+     are  marked  to  be  scanned  on  the fly whenever a file is
+     looked up.
+
+     On success this function return 0. On error  it  returns  1,
+     and  a  description  of the error can be obtained by calling
+     pca_last_error(pc).
+
+
+</pre><h2>LOOKING UP FILES</h2><pre>
+     Once the cache has been populated with files, you  can  look
+     up  the  full  pathname  of a file, simply by specifying its
+     filename to pca_lookup_file().
+
+       char *pca_lookup_file(PathCache *pc, const char *name,
+                             int name_len, int literal);
+
+     To make it possible to pass this function a  filename  which
+     is  actually  part of a longer string, the name_len argument
+     can be used to specify the length of  the  filename  at  the
+     start  of  the  name[]  argument.  If  you  pass -1 for this
+     length, the length of the string  will  be  determined  with
+     strlen().  If  the  name[]  string might contain backslashes
+     that escape the special meanings of spaces and  tabs  within
+     the filename, give the literal argument, the value 0. Other-
+     wise, if backslashes should be treated as normal characters,
+     pass 1 for the value of the literal argument.
+
+
+</pre><h2>FILENAME COMPLETION</h2><pre>
+     Looking up the potential completions of a filename-prefix in
+     the  filename  cache,  is  achieved  by passing the provided
+     pca_path_completions()    callback    function    to     the
+     cpl_complete_word()  function  (see the <a href="cpl_complete_word.html">cpl_complete_word(3)</a>
+     man page).
+
+       CPL_MATCH_FN(pca_path_completions);
+
+     This callback requires that its data argument be  a  pointer
+     to  a PcaPathConf object. Configuration objects of this type
+     are allocated by calling new_PcaPathConf().
+
+       PcaPathConf *new_PcaPathConf(PathCache *pc);
+
+     This function returns an  object  initialized  with  default
+     configuration    parameters,   which   determine   how   the
+     cpl_path_completions() callback function behaves. The  func-
+     tions  which  allow you to individually change these parame-
+     ters are discussed below.
+
+     By default,  the  pca_path_completions()  callback  function
+     searches  backwards for the start of the filename being com-
+     pleted, looking for the first un-escaped space or the  start
+     of  the input line. If you wish to specify a different loca-
+     tion, call ppc_file_start() with  the  index  at  which  the
+     filename  starts  in  the input line. Passing start_index=-1
+     re-enables the default behavior.
+
+       void ppc_file_start(PcaPathConf *ppc, int start_index);
+
+     By default, when pca_path_completions() looks at a  filename
+     in  the input line, each lone backslash in the input line is
+     interpreted as being a special character which  removes  any
+     special significance of the character which follows it, such
+     as a space which should be taken as  part  of  the  filename
+     rather  than  delimiting  the  start  of the filename. These
+     backslashes are thus ignored while looking for  completions,
+     and  subsequently  added  before  spaces,  tabs  and literal
+     backslashes in the list of completions.  To  have  unescaped
+     backslashes    treated    as    normal    characters,   call
+     ppc_literal_escapes() with a non-zero value in  its  literal
+     argument.
+
+       void ppc_literal_escapes(PcaPathConf *ppc, int literal);
+
+     When you have finished with a PcaPathConf variable, you  can
+     pass  it  to  the  del_PcaPathConf()  destructor function to
+     reclaim its memory.
+
+       PcaPathConf *del_PcaPathConf(PcaPathConf *ppc);
+
+</pre><h2>BEING SELECTIVE</h2><pre>
+     If you are only interested in certain types or  files,  such
+     as,  for example, executable files, or files whose names end
+     in a particular suffix, you can arrange for the file comple-
+     tion  and  lookup functions to be selective in the filenames
+     that they return.  This is done by  registering  a  callback
+     function  with your PathCache object. Thereafter, whenever a
+     filename is found which  either  matches  a  filename  being
+     looked  up,  or  matches  a prefix which is being completed,
+     your callback function will be called with the full pathname
+     of  the  file,  plus  any application-specific data that you
+     provide, and if the callback returns 1 the filename will  be
+     reported  as  a  match,  and  if  it  returns  0, it will be
+     ignored.  Suitable callback functions and  their  prototypes
+     should  be declared with the following macro. The CplCheckFn
+     typedef is  also  provided  in  case  you  wish  to  declare
+     pointers to such functions.
+
+       #define CPL_CHECK_FN(fn) int (fn)(void *data, \
+                                         const char *pathname)
+       typedef CPL_CHECK_FN(CplCheckFn);
+
+     Registering one of  these  functions  involves  calling  the
+     pca_set_check_fn()  function.  In  addition  to the callback
+     function, passed via the check_fn argument, you can  pass  a
+     pointer to anything via the data argument. This pointer will
+     be passed on to your callback function,  via  its  own  data
+     argument,  whenever  it is called, so this provides a way to
+     pass appplication specific data to your callback.
+
+       void pca_set_check_fn(PathCache *pc, CplCheckFn *check_fn,
+                             void *data);
+
+     Note that these callbacks are passed the  full  pathname  of
+     each  matching file, so the decision about whether a file is
+     of interest can be based on any property of  the  file,  not
+     just   its   filename.   As   an   example,   the   provided
+     cpl_check_exe() callback function looks  at  the  executable
+     permissions  of  the  file and the permissions of its parent
+     directories, and only returns 1 if the user has execute per-
+     mission to the file. This callback function can thus be used
+     to lookup or complete command names found in the directories
+     listed  in the user's PATH environment variable. The example
+     program given earlier in this man page provides a demonstra-
+     tion of this.
+
+     Beware that if somebody tries to complete an  empty  string,
+     your  callback  will  get  called once for every file in the
+     cache, which could number in the thousands. If your callback
+     does  anything time consuming, this could result in an unac-
+     ceptable delay for the user, so  callbacks  should  be  kept
+     short.
+     To improve performance, whenever one of these  callbacks  is
+     called,  the  choice  that  it makes is cached, and the next
+     time the corresponding file is looked up, instead of calling
+     the  callback  again,  the  cached  record of whether it was
+     accepted or rejected is used. Thus if somebody tries to com-
+     plete an empty string, and hits tab a second time when noth-
+     ing appears to happen, there will only be  one  long  delay,
+     since  the second pass will operate entirely from the cached
+     dispositions of the files. These cached dipositions are dis-
+     carded  whenever  pca_scan_path()  is  called,  and whenever
+     pca_set_check_fn() is called with changed callback  function
+     or data arguments.
+
+
+</pre><h2>ERROR HANDLING</h2><pre>
+     If pca_scan_path() reports that an error occurred by return-
+     ing  1,  you  can obtain a terse description of the error by
+     calling pca_last_error(pc). This returns an internal  string
+     containing an error message.
+
+       const char *pca_last_error(PathCache *pc);
+
+
+
+</pre><h2>CLEANING UP</h2><pre>
+     Once you have finished using a  PathCache  object,  you  can
+     reclaim  its  resources by passing it to the del_PathCache()
+     destructor function. This takes a pointer to  one  of  these
+     objects, and always returns NULL.
+
+       PathCache *del_PathCache(PathCache *pc);
+
+
+</pre><h2>THREAD SAFETY</h2><pre>
+     In multi-threaded programs, you should use the  libtecla_r.a
+     version  of the library. This uses POSIX reentrant functions
+     where available (hence the _r suffix), and disables features
+     that  rely on non-reentrant system functions. In the case of
+     this module, the only disabled feature is  username  comple-
+     tion in ~username/ expressions, in cpl_path_completions().
+
+     Using the libtecla_r.a version of the library, it is safe to
+     use  the facilities of this module in multiple threads, pro-
+     vided that each thread uses a separately allocated PathCache
+     object.  In  other  words,  if  two  threads want to do path
+     searching, they should each call new_PathCache() to allocate
+     their own caches.

+<HEAD><TITLE>The tecla library release notes</TITLE></HEAD>
+<BODY bgcolor=add8e6><PRE>
+This file lists major changes which accompany each new release.
+
+Version 1.4.1:
+
+  This is a maintenance release. It includes minor changes to support
+  Mac OS X (Darwin), the QNX real-time operating system, and Cygwin
+  under Windows. It also fixes an oversight that was preventing the
+  tab key from inserting tab characters when users unbound the
+  complete-word action from it.
+
+Version 1.4.0:
+
+  The contents of the history list can now be saved and restored with
+  the new gl_save_history() and gl_load_history() functions.
+
+  Event handlers can now be registered to watch for and respond to I/O
+  on arbitrary file descriptors while gl_get_line() is waiting for
+  terminal input from the user. See the gl_get_line(3) man page
+  for details on gl_watch_fd().
+
+  As an optional alternative to getting configuration information only
+  from ~/.teclarc, the new gl_configure_getline() function allows
+  configuration commands to be taken from any of, a string, a
+  specified application-specific file, and/or a specified
+  user-specific file. See the gl_get_line(3) man page for details.
+
+  The version number of the library can now be queried using the
+  libtecla_version() function. See the libtecla(3) man page.
+
+  The new gl_group_history() function allows applications to group
+  different types of input line in the history buffer, and arrange for
+  only members of the appropriate group to be recalled on a given call
+  to gl_get_line(). See the gl_get_line(3) man page.
+
+  The new gl_show_history() function displays the current history list
+  to a given stdio output stream. See the gl_get_line(3) man page.
+
+  new_GetLine() now allows you to specify a history buffer size of
+  zero, thus requesting that no history buffer be allocated. You can
+  subsequently resize or delete the history buffer at any time, by
+  calling gl_resize_history(), limit the number of lines that are
+  allowed in the buffer by calling gl_limit_history(), clear either
+  all history lines from the history list, or just the history lines
+  that are associated with the current history group, by calling
+  gl_clear_history, and toggle the history mechanism on and off by
+  calling gl_toggle_history().
+
+  The new gl_terminal_size() function can be used to query the
+  current terminal size. It can also be used to supply a default
+  terminal size on systems where no mechanism is available for
+  looking up the size.
+
+  The contents and configuration of the history list can now be
+  obtained by the calling application, by calling the new
+  gl_lookup_history(), gl_state_of_history(), gl_range_of_history()
+  and gl_size_of_history() functions. See the gl_get_line(3) man page.
+
+  Echoing of the input line as it is typed, can now be turned on and
+  off via the new gl_echo_mode() function. While echoing is disabled,
+  newly entered input lines are omitted from the history list.  See
+  the gl_get_line(3) man page.
+
+  While the default remains to display the prompt string literally,
+  the new gl_prompt_style() function can be used to enable text
+  attribute formatting directives in prompt strings, such as
+  underlining, bold font, and highlighting directives.
+
+  Signal handling in gl_get_line() is now customizable. The default
+  signal handling behavior remains essentially the same, except that
+  the SIGTSTP, SIGTTIN and SIGTTOU are now forwarded to the
+  corresponding signal handler of the calling program, instead of
+  causing a SIGSTOP to be sent to the application.  It is now possible
+  to remove signals from the list that are trapped by gl_get_line(),
+  as well as add new signals to this list. The signal and terminal
+  environments in which the signal handler of the calling program is
+  invoked, and what gl_get_line() does after the signal handler
+  returns, is now customizable on a per signal basis. You can now also
+  query the last signal that was caught by gl_get_line(). This is
+  useful when gl_get_line() aborts with errno=EINTR, and you need to
+  know which signal caused it to abort.
+
+  Key-sequences bound to action functions can now start with printable
+  characters. Previously only keysequences starting with control or
+  meta characters were permitted.
+
+  gl_get_line() is now 8-bit clean. If the calling program has
+  correctly called setlocale(LC_CTYPE,""), then the user can select an
+  alternate locale by setting the standard LC_CTYPE, LC_ALL, or LANG
+  environment variables, and international characters can then be
+  entered directly, either by using a non-US keyboard, or by using a
+  compose key on a standard US keyboard. Note that in locales in which
+  meta characters become printable, meta characters no longer match
+  M-c bindings, which then have to be entered using their escape-c
+  equivalents.  Fortunately most modern terminal emulators either
+  output the escape-c version by default when the meta key is used, or
+  can be configured to do so (see the gl_get_line(3) man page), so in
+  most cases you can continue to use the meta key.
+
+  Completion callback functions can now tell gl_get_line() to return
+  the input line immediately after a successful tab completion, simply
+  by setting the last character of the optional continuation suffix to
+  a newline character (ie. in the call to cpl_add_completion()).
+
+  It is now safe to create and use multiple GetLine objects, albeit
+  still only from a single thread. In conjunction with the new
+  gl_configure_getline() function, this optionally allows multiple
+  GetLine objects with different bindings to be used to implement
+  different input modes.
+
+  The edit-mode configuration command now accepts the argument,
+  none. This tells gl_get_line() to revert to using just the native
+  line editing facilities provided by the terminal driver. This could
+  be used if the termcap or terminfo entry of the host terminal were
+  badly corrupted.
+
+  Application callback functions invoked by gl_get_line() can now
+  change the displayed prompt using the gl_replace_prompt() function.
+
+  Their is now an optional program distributed with the library. This
+  is a beta release of a program which adds tecla command-line editing
+  to virtually any third party application without the application
+  needing to be linked to the library. See the enhance(3) man page for
+  further details. Although built and installed by default, the
+  INSTALL document explains how to prevent this.
+
+  The INSTALL document now explains how you can stop the demo programs
+  from being built and installed.
+
+  NetBSD/termcap fixes. Mike MacFaden reported two problems that he
+  saw when compiling libtecla under NetBSD. Both cases were related to
+  the use of termcap.  Most systems use terminfo, so this problem has
+  gone unnoticed until now, and won't have affected the grand majority
+  of users.  The configure script had a bug which prevented the check
+  for CPP working properly, and getline.c wouldn't compile due to an
+  undeclared variable when USE_TERMCAP was defined. Both problems have
+  now been fixed. Note that if you successfully compiled version
+  1.3.3, this problem didn't affect you.
+
+  An unfortunate and undocumented binding of the key-sequence M-O was
+  shadowing the arrow-key bindings on systems that use ^[OA etc. I
+  have removed this binding (the documented lower case M-o binding
+  remains bound). Under the KDE konsole terminal this was causing the
+  arrow keys to do something other than expected.
+
+  There was a bug in the history list code which could result in
+  strange entries appearing at the start of the history list once
+  enough history lines had been added to the list to cause the
+  circular history buffer to wrap. This is now fixed.
+ 
+Version 1.3.3:
+
+  Signal handling has been re-written, and documentation of its
+  behaviour has been added to the gl_get_line(3) man page. In addition
+  to eliminating race conditions, and appropriately setting errno for
+  those signals that abort gl_get_line(), many more signals are now
+  intercepted, making it less likely that the terminal will be left in
+  raw mode by a signal that isn't trapped by gl_get_line().
+
+  A bug was also fixed that was leaving the terminal in raw mode if
+  the editing mode was changed interactively between vi and emacs.
+  This was only noticeable when running programs from old shells that
+  don't reset terminal modes.
+
+Version 1.3.2:
+
+  Tim Eliseo contributed a number of improvements to vi mode,
+  including a fuller set of vi key-bindings, implementation of the vi
+  constraint that the cursor can't backup past the point at which
+  input mode was entered, and restoration of overwritten characters
+  when backspacing in overwrite mode. There are also now new bindings
+  to allow users to toggle between vi and emacs modes interactively.
+  The terminal bell is now used in some circumstances, such as when an
+  unrecognized key sequence is entered. This can be turned off by the
+  new nobeep option in the tecla configuration file.
+
+  Unrelated to the above, a problem under Linux which prevented ^Q
+  from being used to resume terminal output after the user had pressed
+  ^S, has been fixed.
+
+Version 1.3.1:
+
+  In vi mode a bug was preventing the history-search-backward and
+  history-search-forward actions from doing anything when invoked on
+  empty lines. On empty lines they now act like up-history and
+  down-history respectively, as in emacs mode.
+
+  When creating shared libraries under Linux, the -soname directive
+  was being used incorrectly. The result is that Linux binaries linked
+  with the 1.2.3, 1.2.4 and 1.3.0 versions of the tecla shared
+  libraries, will refuse to see other versions of the shared library
+  until relinked with version 1.3.1 or higher.
+
+  The configure script can now handle the fact that under Solaris-2.6
+  and earlier, the only curses library is a static one that hides in
+  /usr/ccs/lib. Under Linux it now also caters for old versions of GNU
+  ld which don't accept version scripts.
+
+  The demos are now linked against the shared version of the library
+  if possible. Previously they were always linked with the static
+  version.
+
+Version 1.3.0:
+
+  The major change in this release is the addition of an optional vi
+  command-line editing mode in gl_get_line(), along with lots of new
+  action functions to support its bindings. To enable this, first
+  create a ~/.teclarc file if you don't already have one, then add the
+  following line to it.
+
+   edit-mode vi
+
+  The default vi bindings, which are designed to mimic those of the vi
+  editor as closely as possible, are described in the gl_get_line(3)
+  man page.
+
+  A new convenience function called ef_list_expansions() has been
+  added for listing filename expansions. See the ef_list_expansions(3)
+  man page for details. This is used in a new list-glob binding, bound
+  to ^Xg in emacs mode, and ^G in vi input mode.
+
+  A bug has been fixed in the key-binding table expansion code. This
+  bug would have caused problems to anybody who defined more than
+  about 18 personalized key-bindings in their ~/.teclarc file.
+
+Version 1.2.4:
+
+  Buffered I/O is now used for writing to terminals, and where
+  supported, cursor motion is done with move-n-positions terminfo
+  capabilities instead of doing lots of move-1-position requests. This
+  greatly improves how the library feels over slow links.
+
+  You can now optionally compile different architectures in different
+  directories, without having to make multiple copies of the
+  distribution. This is documented in the INSTALL file.
+
+  The ksh ~+ directive is now supported.
+
+  Thanks to Markus Gyger for the above improvements.
+
+  Documentation has been added to the INSTALL file describing features
+  designed to facilitate configuration and installation of the library
+  as part of larger packages. These features are intended to remove
+  the need to modify the tecla distribution's configuration and build
+  procedures when embedding the libtecla distribution in other package
+  distributions.
+
+  A previous fix to stop the cursor from warping when the last
+  character of the input line was in the last column of the terminal,
+  was only being used for the first terminal line of the input line.
+  It is now used for all subsequent lines as well, as originally
+  intended.
+  
+Version 1.2.3:
+
+  The installation procedure has been better automated with the
+  addition of an autoconf configure script. This means that installers
+  can now compile and install the library by typing:
+
+    ./configure
+    make
+    make install
+
+  On all systems this makes at least the normal static version of the
+  tecla library. It also makes the reentrant version if reentrant
+  POSIX functions are detected.  Under Solaris, Linux and HP-UX the
+  configuration script arranges for shared libraries to be compiled in
+  addition to the static libraries.  It is hoped that installers will
+  return information about how to compile shared libraries on other
+  systems, for inclusion in future releases, and to this end, a new
+  PORTING guide has been provided.
+
+  The versioning number scheme has been changed. This release would
+  have been 1.2c, but instead will be refered to as 1.2.3. The
+  versioning scheme, based on conventions used by Sun Microsystems, is
+  described in configure.in.
+
+  The library was also tested under HP-UX, and this revealed two
+  serious bugs, both of which have now been fixed.
+  
+  The first bug prevented the library from writing control codes to
+  terminals on big-endian machines, with the exception of those
+  running under Solaris. This was due to an int variable being used
+  where a char was needed.
+
+  The second bug had the symptom that on systems that don't use the
+  newline character as the control code for moving the cursor down a
+  line, a newline wasn't started when the user hit enter.
+
+Version 1.2b:
+
+  Two more minor bug fixes:
+
+  Many terminals don't wrap the cursor to the next line when a
+  character is written to the rightmost terminal column. Instead, they
+  delay starting a new line until one more character is written, at
+  which point they move the cursor two positions.  gl_get_line()
+  wasn't aware of this, so cursor repositionings just after writing
+  the last character of a column, caused it to erroneously go up a
+  line. This has now been remedied, using a method that should work
+  regardless of whether a terminal exhibits this behavior or not.
+
+  Some systems dynamically record the current terminal dimensions in
+  environment variables called LINES and COLUMNS. On such systems,
+  during the initial terminal setup, these values should override the
+  static values read from the terminal information databases, and now
+  do.  Previously they were only used if the dimensions returned by
+  terminfo/termcap looked bogus.
+
+Version 1.2a:
+
+  This minor release fixes the following two bugs:
+
+  The initial terminal size and subsequent changes thereto, weren't
+  being noticed by gl_get_line(). This was because the test for the
+  existence of TIOCWINSZ was erroneously placed before the inclusion
+  of termios.h. One of the results was that on input lines that
+  spanned more than one terminal line, the cursor occasionally jumped
+  unexpectedly to the previous terminal line.
+
+  On entering a line that wrapped over multiple terminal lines,
+  gl_get_line() simply output a carriage-return line-feed at the point
+  at which the user pressed return. Thus if one typed in such a line,
+  then moved back onto one of the earlier terminal lines before
+  hitting return, the cursor was left on a line containing part of the
+  line that had just been entered. This didn't do any harm, but it
+  looked a mess.
+
+Version 1.2:
+
+  A new facility for looking up and completing filenames in UNIX-style
+  paths has now been added (eg. you can search for, or complete
+  commands using the UNIX PATH environment variable). See the
+  pca_lookup_file(3) man page.
+
+  The already existing filename completion callback can now be made
+  selective in what types of files it lists. See the
+  cpl_complete_word(3) man page.
+
+  Due to its potential to break applications when changed, the use of
+  the publically defined CplFileArgs structure to configure the
+  cpl_file_completions() callback is now deprecated.  The definition
+  of this structure has been frozen, and its documentation has been
+  removed from the man pages.  It will remain supported, but if you
+  have used it, you are recommended to switch to the new method, which
+  involves a new opaque configuration object, allocated via a provided
+  constructor function, configured via accessor functions, and
+  eventually deleted with a provided destructor function. The
+  cpl_file_completions() callback distinguishes which structure type
+  it has been sent by virtue of a code placed at the start of the new
+  structure by the constructor.  It is assumed that no existing
+  applications set the boolean 'escaped' member of the CplFileArgs
+  structure to 4568.  The new method is documented in the
+  cpl_complete_word(3) man page.
+
+Version 1.1j
+
+  This was the initial public release on freshmeat.org.

+# This mapfile (or version script) lists the public symbols that are
+# publically exported by each version of the tecla library. This file
+# has the format required by the Sun and Linux linkers, and also acts
+# as a template from which map files for other systems can be derived
+# with awk or sed.
+#
+# Under Solaris and Linux, this map file is used by ld during shared
+# library creation. It has two purposes:
+#
+# 1. It specifies which symbols in the library are to be made visible
+#    to applications. This has the dual benefits of reducing namespace
+#    polution, and of preventing applications from using private
+#    internal library functions that might change or disappear in
+#    future releases.
+#
+# 2. The information listed in this file is recorded in the shared
+#    library, such that when an application is linked against it, the
+#    linker can record a dependency in the application which says
+#    which is the earliest library version which included all of the
+#    symbols that the application needs. This means that if the
+#    application is copied to another system that has an earlier
+#    version of the library, the linker can quickly determine whether
+#    the earlier version contains all of the symbols that it needs.
+#
+# Under Linux, mapfiles can also be used to allow multiple
+# incompatible versions of a given function to exist in a library,
+# thus supporting applications that were compiled against different
+# incompatible versions of the library. Since this feature (and the
+# inclusion of .symver directives) isn't supported by Solaris, it
+# can't be included in this file. Non backwards compatibility in the
+# ABI must instead be handled in the more traditional way, by
+# incrementing the major version number.
+#
+# When a new minor release is made, a new tecla_1.x specification
+# should be added which inherits the symbols of the previous release
+# and lists newly added functions. For example, below you will find
+# the following clause:
+#
+# tecla_1.3 {
+#    global:
+#	ef_list_expansions;
+# } tecla_1.2;

+.SH DESCRIPTION
+
+The \f3cpl_complete_word()\f1 function is part of the tecla library
+(see the libtecla(3) man page). It is usually called behind the scenes
+by \f3gl_get_line(3)\f1, but can also be called separately.
+
+Given an input line containing an incomplete word to be completed, it
+calls a user-provided callback function (or the provided
+file-completion callback function) to look up all possible completion
+suffixes for that word. The callback function is expected to look
+backward in the line, starting from the specified cursor position, to
+find the start of the word to be completed, then to look up all
+possible completions of that word and record them, one at a time by
+calling \f3cpl_add_completion()\f1.
+
+.sp
+Descriptions of the functions of this module are as follows:
+.sp
+.nf
+  CompleteWord *new_CompleteWord(void)
+.fi
+.sp
+This function creates the resources used by the \f3cpl_complete_word()\f1
+function. In particular, it maintains the memory that is used to
+return the results of calling \f3cpl_complete_word()\f1.
+.sp
+.nf
+  CompleteWord *del_CompleteWord(CompleteWord *cpl)
+.fi
+.sp
+This function deletes the resources that were returned by a previous
+call to \f3new_CompleteWord()\f1. It always returns \f3NULL\f1 (ie. a
+deleted object). It does nothing if the \f3cpl\f1 argument is
+\f3NULL\f1.
+.sp
+The callback functions which lookup possible completions should be
+defined with the following macro (which is defined in libtecla.h).
+.sp
+.nf
+  #define CPL_MATCH_FN(fn) int (fn)(WordCompletion *cpl, \\
+                                    void *data, \\
+                                    const char *line, \\
+                                    int word_end)
+.fi
+.sp
+Functions of this type are called by \f3cpl_complete_word()\f1, and
+all of the arguments of the callback are those that were passed to
+said function. In particular, the \f3line\f1 argument contains the
+input line containing the word to be completed, and \f3word_end\f1 is
+the index of the character that follows the last character of the
+incomplete word within this string. The callback is expected to look
+backwards from \f3word_end\f1 for the start of the incomplete
+word. What constitutes the start of a word clearly depends on the
+application, so it makes sense for the callback to take on this
+responsibility. For example, the builtin filename completion function
+looks backwards until it hits an unescaped space, or the start of the
+line.  Having found the start of the word, the callback should then
+lookup all possible completions of this word, and record each
+completion via separate calls to \f3cpl_add_completion()\f1. If the
+callback needs access to an application-specific symbol table, it can
+pass it and any other data that it needs, via the \f3data\f1
+argument. This removes any need for globals.
+.sp
+The callback function should return 0 if no errors occur. On failure
+it should return 1, and register a terse description of the error by
+calling \f3cpl_record_error()\f1.
+.sp
+.nf
+  void cpl_record_error(WordCompletion *cpl,
+                        const char *errmsg);
+.fi
+.sp
+The last error message recorded by calling \f3cpl_record_error()\f1,
+can subsequently be queried by calling \f3cpl_last_error()\f1, as
+described later.
+.sp
+.nf
+  int cpl_add_completion(WordCompletion *cpl,
+                         const char *line, int word_start,
+                         int word_end, const char *suffix,
+                         const char *type_suffix,
+                         const char *cont_suffix);
+.fi
+.sp
+The \f3cpl_add_completion()\f1 function is called zero or more times
+by the completion callback function to record each possible completion
+in the specified \f3WordCompletion\f1 object. These completions are
+subsequently returned by \f3cpl_complete_word()\f1, as described
+later. The \f3cpl\f1, \f3line\f1, and \f3word_end\f1 arguments should
+be those that were passed to the callback function. The
+\f3word_start\f1 argument should be the index within the input line
+string of the start of the word that is being completed. This should
+equal \f3word_end\f1 if a zero-length string is being completed. The
+\f3suffix\f1 argument is the string that would have to be appended to
+the incomplete word to complete it.  If this needs any quoting
+(eg. the addition of backslashes before special charaters) to be valid
+within the displayed input line, this should be included. A copy of
+the suffix string is allocated internally, so there is no need to
+maintain your copy of the string after \f3cpl_add_completion()\f1
+returns.
+.sp
+Note that in the array of possible completions which the
+\f3cpl_complete_word()\f1 function returns, the suffix recorded by
+\f3cpl_add_completion()\f1 is listed along with the concatentation of
+this suffix with the word that lies between \f3word_start\f1 and
+\f3word_end\f1 in the input line.
+.sp
+The \f3type_suffix\f1 argument specifies an optional string to be
+appended to the completion if it is displayed as part of a list of
+completions by \f3cpl_list_completions()\f1. The intention is that
+this indicate to the user the type of each completion. For example,
+the file completion function places a directory separator after
+completions that are directories, to indicate their nature to the
+user. Similary, if the completion were a function, you could indicate
+this to the user by setting \f3type_suffix\f1 to "()". Note that the
+\f3type_suffix\f1 string isn't copied, so if the argument isn't a
+literal string between speech marks, be sure that the string remains
+valid for at least as long as the results of \f3cpl_complete_word()\f1
+are needed.
+.sp
+The \f3cont_suffix\f1 is a continuation suffix to append to the
+completed word in the input line if this is the only completion. This
+is something that isn't part of the completion itself, but that gives
+the user an indication about how they might continue to extend the
+token.  For example, the file-completion callback function adds a
+directory separator if the completed word is a directory. If the
+completed word were a function name, you could similarly aid the user
+by arranging for an open parenthesis to be appended.

+The \f3cpl_complete_word()\f1 is normally called behind the scenes by
+\f3gl_get_line(3)\f1, but can also be called separately if you
+separately allocate a \f3WordCompletion\f1 object. It performs word
+completion, as described at the beginning of this section. Its first
+argument is a resource object previously returned by
+\f3new_CompleteWord()\f1.  The \f3line\f1 argument is the input line
+string, containing the word to be completed. The \f3word_end\f1
+argument contains the index of the character in the input line, that
+just follows the last character of the word to be completed. When
+called by \f3gl_get_line()\f1, this is the character over which the
+user pressed \f3TAB\f1. The \f3match_fn\f3 argument is the function
+pointer of the callback function which will lookup possible
+completions of the word, as described above, and the \f3data\f1
+argument provides a way for the application to pass arbitrary data to
+the callback function.
+.sp
+If no errors occur, the \f3cpl_complete_word()\f1 function returns a
+pointer to a \f3CplMatches\f1 container, as defined below. This

+When the \f3cpl_complete_word()\f1 function returns multiple possible
+completions, the \f3cpl_list_completions()\f1 function can be called
+upon to list them, suitably arranged across the available width of the
+terminal. It arranges for the displayed columns of completions to all
+have the same width, set by the longest completion. It also appends
+the \f3type_suffix\f1 strings that were recorded with each completion,
+thus indicating their types to the user.
+
+.SH THE BUILT-IN FILENAME-COMPLETION CALLBACK
+
+By default the \f3gl_get_line(3)\f1 function, passes the following
+completion callback function to \f3cpl_complete_word()\f1. This
+function can also be used separately, either by sending it to
+\f3cpl_complete_word()\f1, or by calling it directly from your
+own completion callback function.
+.sp
+.nf
+  CPL_MATCH_FN(cpl_file_completions);
+.fi
+.sp
+Certain aspects of the behavior of this callback can be changed via
+its \f3data\f1 argument. If you are happy with its default behavior
+you can pass \f3NULL\f1 in this argument. Otherwise it should be a
+pointer to a \f3CplFileConf\f1 object, previously allocated by calling
+\f3new_CplFileConf()\f1.
+.sp
+.nf
+  CplFileConf *new_CplFileConf(void);
+.fi
+.sp
+\f3CplFileConf\f1 objects encapsulate the configuration parameters of
+\f3cpl_file_completions()\f1. These parameters, which start out with
+default values, can be changed by calling the accessor functions
+described below.
+.sp
+By default, the \f3cpl_file_completions()\f3 callback function
+searches backwards for the start of the filename being completed,
+looking for the first un-escaped space or the start of the input
+line. If you wish to specify a different location, call
+\f3cfc_file_start()\f1 with the index at which the filename starts in
+the input line. Passing start_index=-1 re-enables the default
+behavior.
+.sp
+.nf
+  void cfc_file_start(CplFileConf *cfc, int start_index);
+.fi
+.sp
+By default, when \f3cpl_file_completions()\f1 looks at a filename in
+the input line, each lone backslash in the input line is interpreted
+as being a special character which removes any special significance of
+the character which follows it, such as a space which should be taken
+as part of the filename rather than delimiting the start of the
+filename. These backslashes are thus ignored while looking for
+completions, and subsequently added before spaces, tabs and literal
+backslashes in the list of completions. To have unescaped backslashes
+treated as normal characters, call \f3cfc_literal_escapes()\f1 with a
+non-zero value in its \f3literal\f1 argument.
+.sp
+.nf
+  void cfc_literal_escapes(CplFileConf *cfc, int literal);
+.fi
+.sp
+By default, \f3cpl_file_completions()\f1 reports all files who's names
+start with the prefix that is being completed. If you only want a
+selected subset of these files to be reported in the list of
+completions, you can arrange this by providing a callback function
+which takes the full pathname of a file, and returns \f30\f1 if the
+file should be ignored, or \f31\f1 if the file should be included in
+the list of completions. To register such a function for use by
+\f3cpl_file_completions()\f1, call \f3cfc_set_check_fn()\f1, and pass
+it a pointer to the function, together with a pointer to any data that
+you would like passed to this callback whenever it is called. Your
+callback can make its decisions based on any property of the file,
+such as the filename itself, whether the file is readable, writable or
+executable, or even based on what the file contains.
+.sp
+.nf
+  #define CPL_CHECK_FN(fn) int (fn)(void *data, \\
+                                    const char *pathname)
+  typedef CPL_CHECK_FN(CplCheckFn);
+
+  void cfc_set_check_fn(CplFileConf *cfc,
+                        CplCheckFn *chk_fn, void *chk_data);
+.fi
+.sp
+The \f3cpl_check_exe()\f1 function is a provided callback of the above
+type, for use with \f3cpl_file_completions()\f1. It returns non-zero
+if the filename that it is given represents a normal file that the
+user has execute permission to. You could use this to have
+\f3cpl_file_completions()\f1 only list completions of executable
+files.
+.sp
+When you have finished with a \f3CplFileConf\f1 variable, you can pass
+it to the \f3del_CplFileConf()\f1 destructor function to reclaim its
+memory.
+.sp
+.nf
+  CplFileConf *del_CplFileConf(CplFileConf *cfc);
+.fi
+.sp
+
+.SH THREAD SAFETY
+
+In multi-threaded programs, you should use the \f3libtecla_r.a\f1
+version of the library. This uses POSIX reentrant functions where
+available (hence the \f3_r\f1 suffix), and disables features that rely
+on non-reentrant system functions. In the case of this module, the
+only disabled feature is username completion in \f3~username/\f1
+expressions, in \f3cpl_file_completions()\f1.
+
+Using the \f3libtecla_r.a\f1 version of the library, it is safe to use
+the facilities of this module in multiple threads, provided that each
+thread uses a separately allocated \f3WordCompletion\f1 object. In
+other words, if two threads want to do word completion, they should
+each call \f3new_WordCompletion()\f1 to allocate their own completion
+objects.

+
+.SH DESCRIPTION
+
+The \f3ef_expand_file()\f1 function is part of the tecla library
+(see the libtecla(3) man page). It expands a specified filename,
+converting \f3~user/\f1 and \f3~/\f1 expressions at the start of the
+filename to the corresponding home directories, replacing
+\f3$envvar\f1 with the value of the corresponding environment
+variable, and then, if there are any wildcards, matching these against
+existing filenames. Backslashes in the input filename are interpreted
+as escaping any special meanings of the characters that follow them.
+Only backslahes that are themselves preceded by backslashes are
+preserved in the expanded filename.
+.sp
+In the presence of wildcards, the returned list of filenames only
+includes the names of existing files which match the
+wildcards. Otherwise, the original filename is returned after
+expansion of tilde and dollar expressions, and the result is not
+checked against existing files. This mimics the file-globbing behavior
+of the unix \f3tcsh\f1 shell.
+.sp
+The supported wildcards and their meanings are:
+.nf
+  *        -  Match any sequence of zero or more characters.
+  ?        -  Match any single character.
+  [chars]  -  Match any single character that appears in
+              'chars'.  If 'chars' contains an expression of
+              the form a-b, then any character between a and
+              b, including a and b, matches. The '-'
+              character looses its special meaning as a
+              range specifier when it appears at the start
+              of the sequence of characters. The ']'
+              character also looses its significance as the
+              terminator of the range expression if it
+              appears immediately after the opening '[', at
+              which point it is treated one of the
+              characters of the range. If you want both '-'
+              and ']' to be part of the range, the '-'
+              should come first and the ']' second.
+              
+  [^chars] -  The same as [chars] except that it matches any
+              single character that doesn't appear in
+              'chars'.
+.fi
+
+Note that wildcards never match the initial dot in filenames that
+start with '.'. The initial '.' must be explicitly specified in the
+filename. This again mimics the globbing behavior of most unix shells,
+and its rational is based in the fact that in unix, files with names
+that start with '.' are usually hidden configuration files, which are
+not listed by default by the ls command.
+.sp
+The following is a complete example of how to use the file expansion
+function.
+
+.nf
+  #include <stdio.h>
+  #include <libtecla.h>
+
+  int main(int argc, char *argv[])
+  {
+    ExpandFile *ef;      /* The expansion resource object */
+    char *filename;      /* The filename being expanded */
+    FileExpansion *expn; /* The results of the expansion */
+    int i;
+
+    ef = new_ExpandFile();
+    if(!ef)
+      return 1;
+
+    for(arg = *(argv++); arg; arg = *(argv++)) {
+      if((expn = ef_expand_file(ef, arg, -1)) == NULL) {
+        fprintf(stderr, "Error expanding %s (%s).\\n", arg,
+                         ef_last_error(ef));
+      } else {
+        printf("%s matches the following files:\\n", arg);
+        for(i=0; i<expn->nfile; i++)
+          printf(" %s\\n", expn->files[i]);
+      }
+    }
+
+    ef = del_ExpandFile(ef);
+    return 0;
+  }
+.fi
+.sp
+Descriptions of the functions used above are as follows:
+.sp
+.nf
+  ExpandFile *new_ExpandFile(void)
+.fi
+.sp
+This function creates the resources used by the \f3ef_expand_file()\f1
+function. In particular, it maintains the memory that is used to record the
+array of matching filenames that is returned by \f3ef_expand_file()\f1. This
+array is expanded as needed, so there is no built in limit to the number of
+files that can be matched.
+.sp
+.nf
+  ExpandFile *del_ExpandFile(ExpandFile *ef)
+.fi
+.sp
+This function deletes the resources that were returned by a previous call to
+\f3new_ExpandFile()\f1. It always returns \f3NULL\f1 (ie a deleted object). It
+does nothing if the \f3ef\f1 argument is \f3NULL\f1.
+.sp
+A container of the following type is returned by \f3ef_expand_file()\f1.
+.sp
+.nf
+  typedef struct {
+    int exists;   /* True if the files in files[] exist */
+    int nfile;    /* The number of files in files[] */
+    char **files; /* An array of 'nfile' filenames. */
+  } FileExpansion;
+.fi
+.sp
+.nf
+  FileExpansion *ef_expand_file(ExpandFile *ef,
+                                const char *path,
+                                int pathlen)
+.fi
+.sp
+The \f3ef_expand_file()\f1 function performs filename expansion, as documented
+at the start of this section. Its first argument is a resource object returned
+by \f3new_ExpandFile()\f1. A pointer to the start of the filename to be matched
+is passed via the \f3path\f1 argument. This must be a normal \f3NUL\f1
+terminated string, but unless a length of -1 is passed in \f3pathlen\f1, only
+the first \f3pathlen\f1 characters will be used in the filename expansion.  If
+the length is specified as -1, the whole of the string will be
+expanded.
+.sp
+The function returns a pointer to a container who's contents are the
+results of the expansion. If there were no wildcards in the filename,
+the \f3nfile\f1 member will be 1, and the \f3exists\f1 member should
+be queried if it is important to know if the expanded file currently
+exists or not. If there were wildcards, then the contained
+\f3files[]\f1 array will contain the names of the \f3nfile\f1 existing
+files that matched the wildcarded filename, and the \f3exists\f1
+member will have the value 1. Note that the returned container belongs
+to the specified \f3ef\f1 object, and its contents will change on each
+call, so if you need to retain the results of more than one call to
+\f3ef_expand_file()\f1, you should either make a private copy of the
+returned results, or create multiple file-expansion resource objects
+via multiple calls to \f3new_ExpandFile()\f1.
+.sp
+On error, \f3NULL\f1 is returned, and an explanation of the error can
+be determined by calling \f3ef_last_error(ef)\f1.
+.sp
+.nf
+  const char *ef_last_error(ExpandFile *ef)
+.fi
+.sp
+This function returns the message which describes the error that
+occurred on the last call to \f3ef_expand_file()\f1, for the given
+\f3(ExpandFile *ef)\f1 resource object.
+.sp
+.nf
+  int ef_list_expansions(FileExpansion *result, FILE *fp,
+                         int terminal_width);
+.fi
+.sp
+The \f3ef_list_expansions()\f1 function provides a convenient way to
+list the filename expansions returned by \f3ef_expand_file()\f1. Like
+the unix \f3ls\f1 command, it arranges the filenames into equal width
+columns, each column having the width of the largest file. The number
+of columns used is thus determined by the length of the longest
+filename, and the specified terminal width. Beware that filenames that
+are longer than the specified terminal width are printed without being
+truncated, so output longer than the specified terminal width can
+occur. The list is written to the stdio stream specified by the
+\f3fp\f1 argument.
+
+.SH THREAD SAFETY
+
+In multi-threaded programs, you should use the \f3libtecla_r.a\f1
+version of the library. This uses POSIX reentrant functions where
+available (hence the \f3_r\f1 suffix), and disables features that rely
+on non-reentrant system functions. Currently there are no features
+disabled in this module.
+
+Using the \f3libtecla_r.a\f1 version of the library, it is safe to use
+the facilities of this module in multiple threads, provided that each
+thread uses a separately allocated \f3ExpandFile\f1 object. In other
+words, if two threads want to do file expansion, they should each call
+\f3new_ExpandFile()\f1 to allocate their own file-expansion objects.

+.SH NAME
+enhance - A program that adds command-line editing to third party programs.
+.SH SYNOPSIS
+.nf
+enhance command [ argument ... ]
+.fi
+
+.SH DESCRIPTION
+
+The \f3enhance\f1 program provides enhanced command-line editing
+facilities to users of third party applications, to which one doesn't
+have any source code. It does this by placing a pseudo-terminal
+between the application and the real terminal. It uses the tecla
+command-line editing library to read input from the real terminal,
+then forwards each just completed input line to the application via
+the pseudo-terminal.  All output from the application is forwarded
+back unchanged to the real terminal.
+.sp
+Whenever the application stops generating output for more than a tenth
+of a second, the \f3enhance\f1 program treats the latest incomplete
+output line as the prompt, and redisplays any incompleted input line
+that the user has typed after it. Note that the small delay, which is
+imperceptible to the user, isn't necessary for correct operation of
+the program. It is just an optimization, designed to stop the input
+line from being redisplayed so often that it slows down output.
+
+.SH DEFICIENCIES
+
+The one major problem that hasn't been solved yet, is how to deal with
+applications that change whether typed input is echo'd by their
+controlling terminal. For example, programs that ask for a password,
+such as ftp and telnet, temporarily tell their controlling terminal
+not to echo what the user types. Since this request goes to the
+application side of the psuedo terminal, the \f3enhance\f1 program has
+no way of knowing that this has happened, and continues to echo typed
+input to its controlling terminal, while the user types their
+password.
+.sp
+Furthermore, before executing the host application, the \f3enhance\f1
+program initially sets the pseudo terminal to noecho mode, so that
+everything that it sends to the program doesn't get redundantly
+echoed. If a program that switches to noecho mode explicitly restores
+echoing afterwards, rather than restoring the terminal modes that were
+previously in force, then subsequently, every time that you enter a
+new input line, a duplicate copy will be displayed on the next line.

+.SH DESCRIPTION
+
+The \f3gl_get_line()\f1 function is part of the tecla library (see
+the libtecla(3) man page). If the user is typing at a terminal, it
+prompts them for an line of input, then provides interactive editing
+facilities, similar to those of the unix \f3tcsh\f1 shell. In addition
+to simple command-line editing, it supports recall of previously
+entered command lines, TAB completion of file names, and in-line
+wild-card expansion of filenames.
+.sp
+.SH AN EXAMPLE
+
+The following shows a complete example of how to use the
+\f3gl_get_line()\f1 function to get input from the user:
+
+.nf
+  #include <stdio.h>
+  #include <locale.h>
+  #include <libtecla.h>
+
+  int main(int argc, char *argv[])
+  { 
+    char *line;    /* The line that the user typed */
+    GetLine *gl;   /* The gl_get_line() resource object */
+
+    setlocale(LC_CTYPE, ""); /* Adopt the user's choice */
+                             /* of character set. */
+
+    gl = new_GetLine(1024, 2048);
+    if(!gl)
+      return 1;
+
+    while((line=gl_get_line(gl, "$ ", NULL, -1)) != NULL &&
+           strcmp(line, "exit\\n") != 0)
+      printf("You typed: %s\\n", line);
+
+    gl = del_GetLine(gl);
+    return 0;
+  }
+.fi
+.sp
+In the example, first the resources needed by the \f3gl_get_line()\f1 function
+are created by calling \f3new_GetLine()\f1. This allocates the memory used in
+subsequent calls to the \f3gl_get_line()\f1 function, including the history
+buffer for recording previously entered lines. Then one or more lines are read
+from the user, until either an error occurs, or the user types \f3exit\f1. Then
+finally the resources that were allocated by \f3new_GetLine()\f1, are returned
+to the system by calling \f3del_GetLine()\f1. Note the use of the \f3NULL\f1
+return value of \f3del_GetLine()\f1 to make \f3gl\f1 \f3NULL\f1. This is a
+safety precaution. If the program subsequently attempts to pass \f3gl\f1 to
+\f3gl_get_line()\f1, said function will complain, and return an error, instead of
+attempting to use the deleted resource object.
+
+.sp
+.SH THE FUNCTIONS USED IN THE EXAMPLE
+The descriptions of the functions used in the example are as follows:
+.sp
+.nf
+  GetLine *new_GetLine(size_t linelen, size_t histlen)
+.fi
+.sp
+This function creates the resources used by the \f3gl_get_line()\f1
+function and returns an opaque pointer to the object that contains
+them.  The maximum length of an input line is specified via the
+\f3linelen\f1 argument, and the number of bytes to allocate for
+storing history lines is set by the \f3histlen\f1 argument. History
+lines are stored back-to-back in a single buffer of this size. Note
+that this means that the number of history lines that can be stored at
+any given time, depends on the lengths of the individual lines.  If
+you want to place an upper limit on the number of lines that can be
+stored, see the \f3gl_limit_history()\f1 function described later. If
+you don't want history at all, specify \f3histlen\f1 as zero, and no
+history buffer will be allocated.
+.sp
+On error, a message is printed to \f3stderr\f1 and \f3NULL\f1 is returned.
+.sp
+.nf
+  GetLine *del_GetLine(GetLine *gl)
+.fi
+.sp
+This function deletes the resources that were returned by a previous
+call to \f3new_GetLine()\f1. It always returns \f3NULL\f1 (ie a
+deleted object). It does nothing if the \f3gl\f1 argument is
+\f3NULL\f1.
+.sp
+.nf
+  char *gl_get_line(GetLine *gl, const char *prompt,
+                   const char *start_line, int start_pos);
+.fi
+.sp
+The \f3gl_get_line()\f1 function can be called any number of
+times to read input from the user. The \f3gl\f1 argument
+must have been previously returned by a call to
+\f3new_GetLine()\f1. The \f3prompt\f1 argument should be a
+normal \f3NUL\f1 terminated string, specifying the prompt to
+present the user with. By default prompts are displayed
+literally, but if enabled with the \f3gl_prompt_style()\f1
+function (see later), prompts can contain directives to do
+underlining, switch to and from bold fonts, or turn
+highlighting on and off.
+
+If you want to specify the initial contents of the line, for
+the user to edit, pass the desired string via the
+\f3start_line\f1 argument. You can then specify which
+character of this line the cursor is initially positioned
+over, using the \f3start_pos\f1 argument. This should be -1
+if you want the cursor to follow the last character of the
+start line. If you don't want to preload the line in this
+manner, send \f3start_line\f1 as \f3NULL\f1, and set
+\f3start_pos\f1 to -1.
+
+The \f3gl_get_line()\f1 function returns a pointer to the line entered
+by the user, or \f3NULL\f1 on error or at the end of the input. The
+returned pointer is part of the specified \f3gl\f1 resource object,
+and thus should not be free'd by the caller, or assumed to be
+unchanging from one call to the next. When reading from a user at a
+terminal, there will always be a newline character at the end of the
+returned line.  When standard input is being taken from a pipe or a
+file, there will similarly be a newline unless the input line was too
+long to store in the internal buffer. In the latter case you should
+call \f3gl_get_line()\f1 again to read the rest of the line. Note that
+this behavior makes \f3gl_get_line()\f1 similar to \f3fgets()\f1.  In
+fact when \f3stdin\f1 isn't connected to a terminal,\f3gl_get_line()\f1
+just calls \f3fgets()\f1.
+
+.SH OPTIONAL PROMPT FORMATTING
+
+Whereas by default the prompt string that you specify is
+displayed literally, without any special interpretation of
+the characters within it, the \f3gl_prompt_style()\f1
+function can be used to enable optional formatting
+directives within the prompt.
+.sp
+.nf
+  void gl_prompt_style(GetLine *gl, GlPromptStyle style);
+.fi
+.sp
+The \f3style\f1 argument, which specifies the formatting
+style, can take any of the following values:
+.sp
+.nf
+  GL_FORMAT_PROMPT   -  In this style, the formatting
+                        directives described below, when
+                        included in prompt strings, are
+                        interpreted as follows:
+
+                          %B  -  Display subsequent
+                                 characters with a bold
+                                 font.
+                          %b  -  Stop displaying characters
+                                 with the bold font.
+                          %F  -  Make subsequent characters
+                                 flash.
+                          %f  -  Turn off flashing
+                                 characters.
+                          %U  -  Underline subsequent
+                                 characters. 
+                          %u  -  Stop underlining
+                                 characters.
+                          %P  -  Switch to a pale (half
+                                 brightness) font.
+                          %p  -  Stop using the pale font.
+                          %S  -  Highlight subsequent
+                                 characters (also known as
+                                 standout mode).
+                          %s  -  Stop highlighting
+                                 characters.
+                          %V  -  Turn on reverse video.
+                          %v  -  Turn off reverse video.
+                          %%  -  Display a single %
+                                 character.
+
+                        For example, in this mode, a prompt
+                        string like \f3"%UOK%u$ "\f1 would
+                        display the prompt \f3"OK$ "\f1,
+                        but with the \f3OK\f1 part
+                        underlined.
+
+                        Note that although a pair of
+                        characters that starts with a %
+                        character, but doesn't match any of
+                        the above directives is displayed
+                        literally, if a new directive is
+                        subsequently introduced which does
+                        match, the displayed prompt will
+                        change, so it is better to always
+                        use %% to display a literal %.
+
+                        Also note that not all terminals
+                        support all of these text
+                        attributes, and that some substitute
+                        a different attribute for missing
+                        ones.

+.SH THE AVAILABLE KEY BINDING FUNCTIONS
+
+The \f3gl_get_line()\f1 function provides a number of functions which
+can be bound to key sequences. The names of these functions, and what
+they do, are given below.
+
+.nf
+  user-interrupt           -  Send a SIGINT signal to the
+                              parent process.
+  abort                    -  Send a SIGABRT signal to the
+                              parent process.
+  suspend                  -  Suspend the parent process.

+                              the cursor and the start of the
+                              line.
+  forward-word             -  Move to the end of the word
+                              which follows the cursor.
+  forward-to-word          -  Move the cursor to the start of

+                              the line unchanged. When
+                              invoked on an empty line, it
+                              signals end-of-input (EOF) to
+                              the caller of gl_get_line().
+  del-char-or-list-or-eof  -  This is intended for binding

+                              When invoked at the end of the
+                              line it displays all possible
+                              completions then redisplays
+                              the line unchanged. When
+                              invoked on an empty line, it
+                              signals end-of-input (EOF) to
+                              the caller of gl_get_line().
+  forward-delete-word      -  Delete the word which follows

+                              under the cursor is also
+                              included in the filename being
+                              expanded, and you are left in
+                              vi insert mode.
+  list-glob                -  List any filenames which match
+                              the wild-card, tilde and dollar

+                              count of > 1 is specified,
+                              only that many of the most
+                              recent lines are displayed.

+  end-of-history           -  Move to the newest line in the
+                              history list (ie. the current
+                              line). Note that in vi mode
+                              this leaves you in command

+                              newline character. The newline
+                              character is normally '\\n',
+                              but will be the first
+                              character of the key-sequence
+                              that invoked the newline
+                              action, if this happens to be
+                              a printable character. If the
+                              action was invoked by the

+                              '\\r' carriage return
+                              character, the line is
+                              appended to the history
+                              buffer.
+  repeat-history           -  Return the line that is being
+                              edited, then arrange for the
+                              next most recent entry in the
+                              history buffer to be recalled
+                              when \f3gl_get_line()\f1 is
+                              next called. Repeatedly
+                              invoking this action causes
+                              successive historical input
+                              lines to be re-executed. Note
+                              that this action is equivalent

+.SH DEFAULT KEY BINDINGS IN EMACS MODE
+
+The following default key bindings, which can be overriden by
+the tecla configuration file, are designed to mimic most of
+the bindings of the unix \f3tcsh\f1 shell, when it is in
+emacs editing mode.
+.sp
+This is the default editing mode of the tecla library.
+.sp
+Note that a key sequence like \f3^A\f1 or \f3C-a\f1 means hold the control-key
+down while pressing the letter \f3A\f1, and that where you see \f3\\E\f1 or
+\f3M-\f1 in a binding, this represents the escape key or the Meta modifier
+key. Also note that to \f3gl_get_line()\f1, pressing the escape key before a
+key is equivalent to pressing the meta key at the same time as that key. Thus
+the key sequence \f3M-p\f1 can be typed in two ways, by pressing the escape
+key, followed by pressing \f3p\f1, or by pressing the Meta key at the same time
+as \f3p\f1.
+.sp
+Under UNIX the terminal driver sets a number of special keys for certain
+functions. The tecla library attempts to use the same keybindings to maintain
+consistency. The key sequences shown for the following 6 bindings are thus just
+examples of what they will probably be set to. If you have used the \f3stty\f1
+command to change these keys, then the default bindings should match.
+

+.fi
+
+The cursor keys are refered to by name, as follows. This is necessary
+because different types of terminals generate different key sequences
+when their cursor keys are pressed.
+
+  right  ->   cursor-right
+  left   ->   cursor-left
+  up     ->   up-history
+  down   ->   down-history
+
+The remaining bindings don't depend on the terminal setttings.

+Note that ^I is what the TAB key generates, and that ^@ can be
+generated not only by pressing the control key and the @ key
+simultaneously, but also by pressing the control key and the space bar
+at the same time.
+
+.SH DEFAULT KEY BINDINGS IN VI MODE
+
+The following default key bindings are designed to mimic the
+vi style of editing as closely as possible. This means that
+very few editing functions are provided in the initial
+character input mode, editing functions instead being
+provided by the vi command mode. Vi command mode is entered
+whenever the escape character is pressed, or whenever a
+key-sequence that starts with a meta character is entered. In
+addition to mimicing vi, libtecla provides bindings for tab
+completion, wild-card expansion of file names, and historical
+line recall.
+.sp
+To learn how to tell the tecla library to use vi mode instead
+of the default emacs editing mode, see the section entitled
+THE TECLA CONFIGURATION FILE.
+.sp
+As already mentioned above in the emacs section, Note that a
+key sequence like \f3^A\f1 or \f3C-a\f1 means hold the
+control-key down while pressing the letter \f3A\f1, and that
+where you see \f3\\E\f1 or \f3M-\f1 in a binding, this
+represents the escape key or the Meta modifier key. Also note
+that to \f3gl_get_line()\f1, pressing the escape key before a
+key is equivalent to pressing the meta key at the same time
+as that key. Thus the key sequence \f3M-p\f1 can be typed in
+two ways, by pressing the escape key, followed by pressing
+\f3p\f1, or by pressing the Meta key at the same time as
+\f3p\f1.
+.sp
+Under UNIX the terminal driver sets a number of special keys
+for certain functions. The tecla library attempts to use the
+same keybindings to maintain consistency, binding them both
+in input mode and in command mode. The key sequences shown
+for the following 6 bindings are thus just examples of what
+they will probably be set to. If you have used the \f3stty\f1
+command to change these keys, then the default bindings
+should match.
+
+.nf
+  ^C     ->   user-interrupt
+  ^\\     ->   abort
+  ^Z     ->   suspend
+  ^Q     ->   start-output
+  ^S     ->   stop-output
+  ^V     ->   literal-next
+  M-^C   ->   user-interrupt
+  M-^\\   ->   abort
+  M-^Z   ->   suspend
+  M-^Q   ->   start-output
+  M-^S   ->   stop-output
+.fi
+
+Note that above, most of the bindings are defined twice, once
+as a raw control code like \f3^C\f1 and then a second time as
+a meta character like \f3M-^C\f1. The former is the binding
+for vi input mode, whereas the latter is the binding for vi
+command mode. Once in command mode all key-sequences that the
+user types that they don't explicitly start with an escape or
+a meta key, have their first key secretly converted to a meta
+character before the key sequence is looked up in the key
+binding table. Thus, once in command mode, when you type the
+letter \f3i\f1, for example, the tecla library actually looks
+up the binding for \f3M-i\f1.
+
+The cursor keys are refered to by name, as follows. This is necessary
+because different types of terminals generate different key sequences
+when their cursor keys are pressed.
+
+  right  ->   cursor-right
+  left   ->   cursor-left
+  up     ->   up-history
+  down   ->   down-history
+
+The cursor keys normally generate a keysequence that start
+with an escape character, so beware that using the arrow keys
+will put you into command mode (if you aren't already in
+command mode).
+.sp
+The following are the terminal-independent key bindings for vi input
+mode.
+
+.nf
+  ^D     ->   list-or-eof
+  ^G     ->   list-glob
+  ^H     ->   backward-delete-char
+  ^I     ->   complete-word
+  \\r     ->   newline
+  \\n     ->   newline
+  ^L     ->   clear-screen
+  ^N     ->   down-history
+  ^P     ->   up-history
+  ^R     ->   redisplay
+  ^U     ->   backward-kill-line
+  ^W     ->   backward-delete-word
+  ^X*    ->   expand-filename
+  ^X^F   ->   read-from-file
+  ^X^R   ->   read-init-files
+  ^?     ->   backward-delete-char
+.fi
+
+The following are the key bindings that are defined in vi
+command mode, this being specified by them all starting with
+a meta character. As mentioned above, once in command mode
+the initial meta character is optional. For example, you
+might enter command mode by typing Esc, and then press h
+twice to move the cursor two positions to the left. Both h
+characters get quietly converted to M-h before being compared
+to the key-binding table, the first one because Escape
+followed by a character is always converted to the equivalent
+meta character, and the second because command mode was
+already active.

+.fi
+
+Note that ^I is what the TAB key generates.
+
+.SH ENTERING REPEAT COUNTS
+
+Many of the key binding functions described previously, take
+an optional count, typed in before the target
+keysequence. This is interpreted as a repeat count by most
+bindings. A notable exception is the goto-column binding,
+which interprets the count as a column number.
+.sp
+By default you can specify this count argument by pressing
+the meta key while typing in the numeric count. This relies
+on the \f3digit-argument\f1 action being bound to Meta-0,
+Meta-1 etc.  Once any one of these bindings has been
+activated, you can optionally take your finger off the meta
+key to type in the rest of the number, since every numeric
+digit thereafter is treated as part of the number, unless it
+is preceded by the \f3literal-next\f1 binding. As soon as a
+non-digit, or literal digit key is pressed the repeat count
+is terminated and either causes the just typed character to
+be added to the line that many times, or causes the next
+key-binding function to be given that argument.
+.sp
+For example, in emacs mode, typing:
+.sp
+.nf
+  M-12a
+.fi
+.sp
+causes the letter 'a' to be added to the line 12 times,
+whereas
+.sp
+.nf
+  M-4M-c
+.fi
+.sp
+Capitalizes the next 4 words.
+.sp
+In vi command mode the Meta modifier is automatically added
+to all characters typed in, so to enter a count in vi
+command-mode, just involves typing in the number, just as at
+it does in the vi editor itself. So for example, in vi
+command mode, typing:
+.sp
+.nf
+  4w2x
+.fi
+.sp
+moves the cursor four words to the right, then deletes two characters.
+.sp
+You can also bind \f3digit-argument\f1 to other key sequences. If
+these end in a numeric digit, that digit gets appended to the current
+repeat count. If it doesn't end in a numeric digit, a new repeat count
+is started with a value of zero, and can be completed by typing in the
+number, after letting go of the key which triggered the digit-argument
+action.
+
+.SH THE TECLA CONFIGURATION FILE
+
+By default, the first call to \f3gl_get_line()\f1 looks for a file
+called \f3\&.teclarc\f1 in your home directory (ie. \f3~/.teclarc\f1).
+If it finds this file, it reads it, interpreting each line as defining
+a new key binding or an editing configuration option. Since the emacs
+keybindings are installed by default, if you want to use the
+non-default vi editing mode, the most important item to go in this
+file is the following line:
+
+.nf
+  edit-mode vi
+.fi
+
+This will re-configure the default bindings for vi-mode. The
+complete set of arguments that this command accepts are:
+.sp
+.nf
+  vi     -  Install key-bindings like those of the vi
+            editor.
+  emacs  -  Install key-bindings like those of the emacs
+            editor. This is the default.
+  none   -  Use just the native line editing facilities
+            provided by the terminal driver.
+.fi
+.sp
+To prevent the terminal bell from being rung, such as when
+an unrecognized control-sequence is typed, place the
+following line in the configuration file:
+
+.nf
+  nobeep
+.fi
+
+An example of a key binding line in the configuration file is
+the following.
+
+.nf
+  bind M-[2~ insert-mode
+.fi
+
+On many keyboards, the above key sequence is generated when one
+presses the \f3insert\f1 key, so with this keybinding, one can toggle
+between the emacs-mode insert and overwrite modes by hitting one
+key. One could also do it by typing out the above sequence of
+characters one by one. As explained above, the \f3M-\f1 part of this
+sequence can be typed either by pressing the escape key before the
+following key, or by pressing the Meta key at the same time as the
+following key. Thus if you had set the above key binding, and the
+insert key on your keyboard didn't generate the above key sequence,
+you could still type it in either of the following 2 ways.
+
+.nf
+  1. Hit the escape key momentarily, then press '[', then '2', then
+     finally '~'.
+
+  2. Press the meta key at the same time as pressing the '[' key,
+     then press '2', then '~'.
+.fi
+
+If you set a keybinding for a key-sequence that is already bound to a function,
+the new binding overrides the old one. If in the new binding you omit the name
+of the new function to bind to the key-sequence, the original binding becomes
+undefined.
+.sp
+Starting with versions of libtecla later than 1.3.3 it is now possible
+to bind keysequences that begin with a printable character. Previously
+key-sequences were required to start with a control or meta character.
+.sp
+Note that the special keywords "up", "down", "left" and "right" refer
+to the arrow keys, and are thus not treated as keysequences. So, for
+example, to rebind the up and down arrow keys to use the history
+search mechanism instead of the simple history recall method, you
+could place the following in your configuration file:
+
+.nf
+  bind up history-search-backwards
+  bind down history-search-backwards
+.fi
+.sp
+To unbind an existing binding, you can do this with the bind command
+by omitting to name any action to rebind the key sequence to.  For
+example, by not specifying an action function, the following command
+unbinds the default beginning-of-line action from the ^A key sequence:
+
+.nf
+  bind ^A
+.fi
+
+.SH ALTERNATE CONFIGURATION SOURCES
+
+As mentioned above, by default users have the option of configuring
+the behavior of \f3gl_get_line()\f1 via a configuration file called
+\f3\&.teclarc\f1 in their home directories. The fact that all
+applications share this same configuration file is both an advantage
+and a disadvantage.  In most cases it is an advantage, since it
+encourages uniformity, and frees the user from having to configure
+each application separately.  In some applications, however, this
+single means of configuration is a problem. This is particularly true
+of embedded software, where there's no filesystem to read a
+configuration file from, and also in applications where a radically
+different choice of keybindings is needed to emulate a legacy keyboard
+interface.  To cater for such cases, the following function allows the
+application to control where configuration information is read from.
+
+.sp
+.nf
+  int gl_configure_getline(GetLine *gl,
+                           const char *app_string,
+                           const char *app_file,
+                           const char *user_file);
+.fi
+.sp
+
+It allows the configuration commands that would normally be read from
+a user's \f3~/.teclarc\f1 file, to be read from any or none of, a
+string, an application specific configuration file, and/or a
+user-specific configuration file. If this function is called before
+the first call to \f3gl_get_line()\f1, the default behavior of
+reading \f3~/.teclarc\f1 on the first call to \f3gl_get_line()\f1 is
+disabled, so all configuration must be achieved using the
+configuration sources specified with this function.
+
+If \f3app_string != NULL\f1, then it is interpreted as a string
+containing one or more configuration commands, separated from each
+other in the string by embedded newline characters. If \f3app_file !=
+NULL\f1 then it is interpreted as the full pathname of an
+application-specific configuration file. If \f3user_file != NULL\f1
+then it is interpreted as the full pathname of a user-specific
+configuration file, such as \f3~/.teclarc\f1. For example, in the
+following call,
+
+  gl_configure_getline(gl, "edit-mode vi \\n nobeep",
+                           "/usr/share/myapp/teclarc",
+                           "~/.teclarc");
+
+the \f3app_string\f1 argument causes the calling application to start
+in vi edit-mode, instead of the default emacs mode, and turns off the
+use of the terminal bell by the library. It then attempts to read
+system-wide configuration commands from an optional file called
+\f3/usr/share/myapp/teclarc\f1, then finally reads user-specific
+configuration commands from an optional \f3\&.teclarc\f1 file in the
+user's home directory. Note that the arguments are listed in ascending
+order of priority, with the contents of \f3app_string\f1 being
+potentially overriden by commands in \f3app_file\f1, and commands in
+\f3app_file\f1 potentially being overriden by commands in
+\f3user_file\f1.
+.sp
+You can call this function as many times as needed, the results being
+cumulative, but note that copies of any filenames specified via the
+\f3app_file\f1 and \f3user_file\f1 arguments are recorded internally
+for subsequent use by the \f3read-init-files\f1 key-binding function,
+so if you plan to call this function multiple times, be sure that the
+last call specifies the filenames that you want re-read when the user
+requests that the configuration files be re-read.
+
+.SH FILENAME AND TILDE COMPLETION
+
+With the default key bindings, pressing the TAB key (aka. ^I) results
+in \f3gl_get_line()\f1 attempting to complete the incomplete filename
+that precedes the cursor. \f3gl_get_line()\f1 searches backwards from
+the cursor, looking for the start of the filename, stopping when it
+hits either a space or the start of the line. If more than one file
+has the specified prefix, \f3gl_get_line()\f1 completes the filename
+up to the point at which the ambiguous matches start to differ, then
+lists the possible matches.
+.sp
+In addition to literally written filenames, \f3gl_get_line()\f1 can
+complete files that start with \f3~/\f1 and \f3~user/\f1 expressions
+and that contain \f3$envvar\f1 expressions. In particular, if you hit
+TAB within an incomplete \f3~user\f1, expression, \f3gl_get_line()\f1
+will attempt to complete the username, listing any ambiguous matches.
+.sp
+The completion binding is implemented using the
+\f3cpl_word_completions()\f1 function, which is also available
+separately to users of this library. See the
+\f3cpl_word_completions(3)\f1 man page for more details.
+
+.SH CUSTOMIZED WORD COMPLETION
+
+If in your application, you would like to have TAB completion complete
+other things in addition to or instead of filenames, you can arrange
+this by registering an alternate completion callback function, via a
+call to the \f3gl_customize_completion()\f1 function.
+.sp
+.nf
+  int gl_customize_completion(GetLine *gl, void *data,
+                              CplMatchFn *match_fn);
+.fi
+.sp
+The \f3data\f1 argument provides a way for your application to pass
+arbitrary, application-specific information to the callback
+function. This is passed to the callback every time that it is
+called. It might for example, point to the symbol table from which
+possible completions are to be sought. The \f3match_fn\f1 argument
+specifies the callback function to be called. The \f3CplMatchFn\f1
+function type is defined in \f3libtecla.h\f1, as is a
+\f3CPL_MATCH_FN()\f1 macro that you can use to declare and prototype
+callback functions. The declaration and responsibilities of callback
+functions are described in depth in the \f1cpl_complete_word(3)\f1 man
+page.
+.sp
+In brief, the callback function is responsible for looking backwards
+in the input line, back from the point at which the user pressed TAB,
+to find the start of the word being completed. It then must lookup
+possible completions of this word, and record them one by one in the
+\f3WordCompletion\f1 object that is passed to it as an argument, by
+calling the \f3cpl_add_completion()\f1 function. If the callback
+function wishes to provide filename completion in addition to its own
+specific completions, it has the option of itself calling the builtin
+file-name completion callback. This also, is documented in the
+\f3cpl_complete_word(3)\f1 man page.
+.sp
+Note that if you would like \f3gl_get_line()\f1 to return the current
+input line when a successful completion is been made, you can arrange
+this when you call \f3cpl_add_completion()\f1, by making the last
+character of the continuation suffix a newline character. If you do
+this, the input line will be updated to display the completion,
+together with any contiuation suffix up to the newline character, then
+\f3gl_get_line()\f1 will return this input line.
+
+.SH FILENAME EXPANSION
+
+With the default key bindings, pressing \f3^X*\f1 causes
+\f3gl_get_line()\f1 to expand the filename that precedes the cursor,
+replacing \f3~/\f1 and \f3~user/\f1 expressions with the corresponding
+home directories, and replacing \f3$envvar\f1 expressions with the
+value of the specified environment variable, then if there are any
+wildcards, replacing the so far expanded filename with a
+space-separated list of the files which match the wild cards.
+.sp
+The expansion binding is implemented using the \f3ef_expand_file()\f1 function.
+See the \f3ef_expand_file(3)\f1 man page for more details.
+
+.SH RECALLING PREVIOUSLY TYPED LINES
+
+Every time that a new line is entered by the user, it is appended to a
+list of historical input lines maintained within the GetLine resource
+object. You can traverse up and down this list using the up and down
+arrow keys. Alternatively, you can do the same with the \f3^P\f1, and
+\f3^N\f1 keys, and in vi command mode you can alternatively use the k
+and j characters. Thus pressing up-arrow once, replaces the current
+input line with the previously entered line. Pressing up-arrow again,
+replaces this with the line that was entered before it, etc.. Having
+gone back one or more lines into the history list, one can return to
+newer lines by pressing down-arrow one or more times. If you do this
+sufficient times, you will return to the original line that you were
+entering when you first hit up-arrow.
+.sp
+Note that in vi mode, all of the history recall functions switch the
+library into command mode.
+.sp
+In emacs mode the \f3M-p\f1 and \f3M-n\f1 keys work just like the
+\f3^P\f1 and \f3^N\f1 keys, except that they skip all but those
+historical lines which share the prefix that precedes the cursor. In
+vi command mode the upper case \f3K\f1 and \f3J\f1 characters do the
+same thing, except that the string that they search for includes the
+character under the cursor as well as what precedes it.
+.sp
+Thus for example, suppose that you were in emacs mode, and you had
+just entered the following list of commands in the order shown:
+
+.nf
+  ls ~/tecla/
+  cd ~/tecla
+  ls -l getline.c
+  emacs ~/tecla/getline.c
+.fi
+
+If you next typed:
+
+.nf
+  ls
+.fi
+
+and then hit \f3M-p\f1, then rather than returning the previously
+typed emacs line, which doesn't start with "ls", \f3gl_get_line()\f1
+would recall the "ls -l getline.c" line. Pressing \f3M-p\f1 again
+would recall the "ls ~/tecla/" line.
+
+.SH HISTORY FILES
+
+To save the contents of the history buffer before quitting your
+application, and subsequently restore them when you next start the
+application, the following functions are provided.
+
+.sp
+.nf
+ int gl_save_history(GetLine *gl, const char *filename,
+                     const char *comment, int max_lines);
+ int gl_load_history(GetLine *gl, const char *filename,
+                     const char *comment);
+.fi
+.sp
+
+The \f3filename\f1 argument specifies the name to give the history
+file when saving, or the name of an existing history file, when
+loading. This may contain home-directory and environment variable
+expressions, such as "~/.myapp_history" or "$HOME/.myapp_history".
+.sp
+Along with each history line, extra information about it, such as when
+it was entered by the user, and what its nesting level is, is recorded
+as a comment preceding the line in the history file. Writing this as a
+comment allows the history file to double as a command file, just in
+case you wish to replay a whole session using it. Since comment
+prefixes differ in different languages, the \f3comment\f1 argument is
+provided for specifying the comment prefix. For example, if your
+application were a unix shell, such as the bourne shell, you would
+specify "#" here. Whatever you choose for the comment character, you
+must specify the same prefix to \f3gl_load_history()\f1 that you used
+when you called \f3gl_save_history()\f1 to write the history file.
+.sp
+The \f3max_lines\f1 must be either -1 to specify that all lines in the
+history list be saved, or a positive number specifying a ceiling on
+how many of the most recent lines should be saved.
+.sp
+Both fuctions return non-zero on error, after writing an error message
+to stderr. Note that \f3gl_load_history()\f1 does not consider the
+non-existence of a file to be an error.
+
+.SH MULTIPLE HISTORY LISTS
+
+If your application uses a single \f3GetLine\f1 object for entering
+many different types of input lines, you may wish \f3gl_get_line()\f1
+to distinguish the different types of lines in the history list, and
+only recall lines that match the current type of line. To support this
+requirement, \f3gl_get_line()\f1 marks lines being recorded in the
+history list with an integer identifier chosen by the application.
+Initially this identifier is set to \f10\f3 by \f3new_GetLine()\f1,
+but it can be changed subsequently by calling
+\f3gl_group_history()\f1.
+
+.sp
+.nf
+  int gl_group_history(GetLine *gl, unsigned id);
+.fi
+.sp
+
+The integer identifier \f3id\f1 can be any number chosen by the
+application, but note that \f3gl_save_history()\f1 and
+\f3gl_load_history()\f1 preserve the association between identifiers
+and historical input lines between program invokations, so you should
+choose fixed identifiers for the different types of input line used by
+your application.
+.sp
+Whenever \f3gl_get_line()\f1 appends a new input line to the history
+list, the current history identifier is recorded with it, and when it
+is asked to recall a historical input line, it only recalls lines that
+are marked with the current identifier.
+
+.SH DISPLAYING HISTORY
+
+The history list can be displayed by calling \f3gl_show_history()\f1.
+
+.sp
+.nf
+  int gl_show_history(GetLine *gl, FILE *fp,
+                      const char *fmt,
+                      int all_groups,
+                      int max_lines);
+.fi
+.sp
+
+This displays the current contents of the history list to the stdio
+output stream \f3fp\f1. If the \f3max_lines\f1 argument is greater
+than or equal to zero, then no more than this number of the most
+recent lines will be displayed. If the \f3all_groups\f1 argument is
+non-zero, lines from all history groups are displayed. Otherwise just
+those of the currently selected history group are displayed. The
+format string argument, \f3fmt\f1, determines how the line is
+displayed. This can contain arbitrary characters which are written
+verbatim, interleaved with any of the following format directives:
+
+.nf
+  %D  -  The date on which the line was originally
+         entered, formatted like 2001-11-20.
+  %T  -  The time of day when the line was entered,
+         formatted like 23:59:59.
+  %N  -  The sequential entry number of the line in
+         the history buffer.
+  %G  -  The number of the history group which the
+         line belongs to.
+  %%  -  A literal % character.
+  %H  -  The history line itself.
+.fi
+
+Thus a format string like \f3"%D %T  %H\n"\f1 would output something like:
+
+.nf
+  2001-11-20 10:23:34  Hello world
+.fi
+
+Note the inclusion of an explicit newline character in the format
+string.
+
+.SH LOOKING UP HISTORY
+
+The \f3gl_lookup_history()\f1 function allows the calling application
+to look up lines in the history list.
+
+.sp
+.nf
+  typedef struct {
+    const char *line;    /* The requested historical */
+                         /*  line. */
+    unsigned group;      /* The history group to which */
+                         /*  the line belongs. */
+    time_t timestamp;    /* The date and time at which */
+                         /*  the line was originally */
+                         /*  entered. */
+  } GlHistoryLine;
+
+  int gl_lookup_history(GetLine *gl, unsigned long id,
+                        GlHistoryLine *hline);
+.fi
+.sp  
+
+The \f3id\f1 argument indicates which line to look up, where the first
+line that was entered in the history list after \f3new_GetLine()\f1
+was called, is denoted by 0, and subsequently entered lines are
+denoted with successively higher numbers. Note that the range of lines
+currently preserved in the history list can be queried by calling the
+\f3gl_range_of_history()\f1 function, described later. If the
+requested line is in the history list, the details of the line are
+recorded in the variable pointed to by the \f3hline\f1 argument, and
+\f31\f1 is returned. Otherwise \f30\f1 is returned, and the variable
+pointed to by \f3hline\f1 is left unchanged.
+.sp
+Beware that the string returned in \f3hline->line\f1 is part of the
+history buffer, so it must not be modified by the caller, and will be
+recycled on the next call to any function that takes \f3gl\f1 as its
+argument. Therefore you should make a private copy of this string if
+you need to keep it around.
+
+.SH MISCELLANEOUS HISTORY CONFIGURATION
+
+If you wish to change the size of the history buffer that was
+originally specified in the call to \f3new_GetLine()\f1, you can do so
+with the \f3gl_resize_history()\f1 function.
+
+.sp
+.nf
+  int gl_resize_history(GetLine *gl, size_t histlen);
+.fi
+.sp
+
+The \f3histlen\f1 argument specifies the new size in bytes, and if you
+specify this as 0, the buffer will be deleted.
+.sp
+As mentioned in the discussion of \f3new_GetLine()\f1, the number of
+lines that can be stored in the history buffer, depends on the lengths
+of the individual lines. For example, a 1000 byte buffer could equally
+store 10 lines of average length 100 bytes, or 2 lines of average
+length 50 bytes. Although the buffer is never expanded when new lines
+are added, a list of pointers into the buffer does get expanded when
+needed to accomodate the number of lines currently stored in the
+buffer. To place an upper limit on the number of lines in the buffer,
+and thus a ceiling on the amount of memory used in this list, you can
+call the \f3gl_limit_history()\f1 function.
+
+.sp
+.nf
+  void gl_limit_history(GetLine *gl, int max_lines);
+.fi
+.sp
+
+The \f3max_lines\f1 should either be a positive number \f3>= 0\f1,
+specifying an upper limit on the number of lines in the buffer, or be
+\f3-1\f1 to cancel any previously specified limit. When a limit is in
+effect, only the \f3max_lines\f1 most recently appended lines are kept
+in the buffer. Older lines are discarded.
+.sp
+To discard lines from the history buffer, use the
+\f3gl_clear_history()\f1 function.
+.sp
+.nf
+  void gl_clear_history(GetLine *gl, int all_groups);
+.fi
+.sp
+The \f3all_groups\f1 argument tells the function whether to delete
+just the lines associated with the current history group (see
+\f3gl_group_history()\f1), or all historical lines in the buffer.
+.sp
+The \f3gl_toggle_history()\f1 function allows you to toggle history on
+and off without losing the current contents of the history list.
+
+.sp
+.nf
+  void gl_toggle_history(GetLine *gl, int enable);
+.fi
+.sp
+
+Setting the \f3enable\f1 argument to 0 turns off the history
+mechanism, and setting it to 1 turns it back on. When history is
+turned off, no new lines will be added to the history list, and
+history lookup key-bindings will act as though there is nothing in the
+history buffer.
+
+.SH QUERYING HISTORY INFORMATION
+
+The configured state of the history list can be queried with the
+\f3gl_history_state()\f1 function.
+
+.sp
+.nf
+  typedef struct {
+    int enabled;     /* True if history is enabled */
+    unsigned group;  /* The current history group */
+    int max_lines;   /* The current upper limit on the */
+                     /*  number of lines in the history */
+                     /*  list, or -1 if unlimited. */
+  } GlHistoryState;
+
+  void gl_state_of_history(GetLine *gl,
+                           GlHistoryState *state);
+.fi
+.sp
+On return, the status information is recorded in the variable pointed
+to by the \f3state\f1 argument.
+.sp
+The \f3gl_range_of_history()\f1 function returns the number and
+range of lines in the history list.
+
+.sp
+.nf
+typedef struct {
+  unsigned long oldest;  /* The sequential entry number */
+                         /*  of the oldest line in the */
+                         /*  history list. */
+  unsigned long newest;  /* The sequential entry number */
+                         /*  of the newest line in the */
+                         /*  history list. */
+  int nlines;            /* The number of lines in the */
+                         /*  history list. */
+} GlHistoryRange;
+
+void gl_range_of_history(GetLine *gl, GlHistoryRange *range);
+.fi
+.sp
+The return values are recorded in the variable pointed to by the
+\f3range\f1 argument. If the \f3nlines\f1 member of this structure is
+greater than zero, then the \f3oldest\f1 and \f3newest\f1 members
+report the range of lines in the list, and \f3newest=oldest+nlines-1\f1.
+Otherwise they are both zero.
+.sp
+The \f3gl_size_of_history()\f1 function returns the total size of the
+history buffer and the amount of the buffer that is currently
+occupied.
+.sp
+.nf
+  typedef struct {
+    size_t size;      /* The size of the history buffer */
+                      /*  (bytes). */
+    size_t used;      /* The number of bytes of the */
+                      /*  history buffer that are */
+                      /*  currently occupied. */
+  } GlHistorySize;
+
+  void gl_size_of_history(GetLine *gl, GlHistorySize *size);
+.fi
+.sp
+On return, the size information is recorded in the variable pointed to
+by the \f3size\f1 argument.
+
+.SH CHANGING TERMINALS
+
+The \f3new_GetLine()\f1 constructor function assumes that input is to
+be read from \f3stdin\f1, and output written to \f3stdout\f1. The
+following function allows you to switch to different input and output
+streams.
+.sp
+.nf
+  int gl_change_terminal(GetLine *gl, FILE *input_fp,
+                         FILE *output_fp, const char *term);
+.fi
+.sp
+The \f3gl\f1 argument is the object that was returned by
+\f3new_GetLine()\f1.  The \f3input_fp\f1 argument specifies the stream
+to read from, and \f3output_fp\f1 specifies the stream to be written
+to. Only if both of these refer to a terminal, will interactive
+terminal input be enabled.  Otherwise \f3gl_get_line()\f1 will simply
+call \f3fgets()\f1 to read command input. If both streams refer to a
+terminal, then they must refer to the same terminal, and the type of
+this terminal must be specified via the \f3term\f1 argument. The value
+of the \f3term\f1 argument is looked up in the terminal information
+database (terminfo or termcap), in order to determine which special
+control sequences are needed to control various aspects of the
+terminal. \f3new_GetLine()\f1 for example, passes the return value of
+\f3getenv("TERM")\f1 in this argument. Note that if one or both of
+\f3input_fp\f1 and \f3output_fp\f1 don't refer to a terminal, then it
+is legal to pass \f3NULL\f1 instead of a terminal type.
+.sp
+Note that if you want to pass file descriptors to
+\f3gl_change_terminal()\f1, you can do this by creating stdio stream
+wrappers using the POSIX \f3fdopen()\f1 function.
+
+.SH EXTERNAL EVENT HANDLING
+
+While \f3gl_get_line()\f1 is waiting for keyboard input from the user,
+you can ask it to also watch for activity on arbitrary file
+descriptors, such as network sockets, pipes etc, and have it call
+functions of your choosing when activity is seen. This works on any
+system that has the \f3select()\f1 system call, which is most, if not
+all flavors of unix. Registering a file descriptor to be watched by
+\f3gl_get_line()\f1 involves calling the \f3gl_watch_fd()\f1 function.
+
+.sp
+.nf
+  int gl_watch_fd(GetLine *gl, int fd, GlFdEvent event,
+                  GlFdEventFn *callback, void *data);
+.fi
+.sp
+
+If this returns non-zero, then it means that either your arguments are
+invalid, or that this facility isn't supported on the host system.
+.sp
+The \f3fd\f1 argument is the file descriptor to be watched. The
+\f3event\f1 argument specifies what type of activity is of interest,
+chosen from the following enumerated values:
+
+.sp
+.nf
+  GLFD_READ   -  Watch for the arrival of data to be read.
+  GLFD_WRITE  -  Watch for the ability to write to the file
+                 descriptor without blocking.
+  GLFD_URGENT -  Watch for the arrival of urgent
+                 out-of-band data on the file descriptor.
+.fi
+.sp
+
+The \f3callback\f1 argument is the function to call when the selected
+activity is seen. It should be defined with the following macro, which
+is defined in libtecla.h.
+
+.sp
+.nf
+  #define GL_FD_EVENT_FN(fn) GlFdStatus (fn)(GetLine *gl, \\
+                                      void *data, int fd, \\
+                                      GlFdEvent event)
+.fi
+.sp
+The \f3data\f1 argument of the \f3gl_watch_fd()\f1 function is passed
+to the callback function for its own use, and can point to anything
+you like, including \f3NULL\f1. The file descriptor and the event
+argument are also passed to the callback function, and this
+potentially allows the same callback function to be registered to more
+than one type of event and/or more than one file descriptor. The
+return value of the callback function should be one of the following
+values.
+
+.sp
+.nf
+  GLFD_ABORT    -  Tell gl_get_line() to abort with an
+                   error (errno won't be set, so set it
+                   appropriately yourself if you need it).
+  GLFD_REFRESH  -  Redraw the input line then continue
+                   waiting for input. Return this if
+                   your callback wrote to the terminal.
+  GLFD_CONTINUE -  Continue to wait for input, without
+                   redrawing the line.
+.fi
+.sp
+Note that before calling the callback, \f3gl_get_line()\f1 blocks most
+signals, and leaves its own signal handlers installed, so if you need
+to catch a particular signal you will need to both temporarily install
+your own signal handler, and unblock the signal. Be sure to re-block
+the signal (if it was originally blocked) and reinstate the original
+signal handler, if any, before returning.
+.sp
+Your callback shouldn't try to read from the terminal, which is left
+in raw mode as far as input is concerned. You can however write to the
+terminal as usual, since features like conversion of newline to
+carriage-return/linefeed are re-enabled while the callback is
+running. If your callback function does write to the terminal, be sure
+to output a newline first, and when your callback returns, tell
+\f3gl_get_line()\f1 that the input line needs to be redrawn, by
+returning the \f3GLFD_REFRESH\f1 status code.
+.sp
+To remove a callback function that you previously registered for a
+given file descriptor and event, simply call \f3gl_watch_fd()\f1 with
+the same file descriptor and \f3event\f1 arguments, but with a
+\f3callback\f1 argument of \f30\f1. The \f3data\f1 argument is ignored
+in this case.
+
+.SH SIGNAL HANDLING DEFAULTS
+
+By default, the \f3gl_get_line()\f1 function intercepts a
+number of signals. This is particularly important for
+signals which would by default terminate the process, since
+the terminal needs to be restored to a usable state before
+this happens. In this section, the signals that are trapped
+by default, and how gl_get_line() responds to them, is
+described. Changing these defaults is the topic of the
+following section.
+.sp
+When the following subset of signals are caught, \f3gl_get_line()\f1
+first restores the terminal settings and signal handling to how they
+were before \f3gl_get_line()\f1 was called, resends the signal, to
+allow the calling application's signal handlers to handle it, then if
+the process still exists, \f3gl_get_line()\f1 returns \f3NULL\f1 and
+sets \f3errno\f1 as specified below.
+
+.sp
+.nf
+ SIGINT  -  This signal is generated both by the keyboard
+            interrupt key (usually ^C), and the keyboard
+            break key.
+
+            errno=EINTR
+
+ SIGHUP  -  This signal is generated when the controlling
+            terminal exits.
+
+            errno=ENOTTY
+
+ SIGPIPE -  This signal is generated when a program attempts
+            to write to a pipe who's remote end isn't being
+            read by any process. This can happen for example
+            if you have called \f3gl_change_terminal()\f1 to
+            redirect output to a pipe hidden under a pseudo
+            terminal.
+
+            errno=EPIPE
+
+ SIGQUIT -  This signal is generated by the keyboard quit
+            key (usually ^\\).
+
+            errno=EINTR
+
+ SIGABRT -  This signal is generated by the standard C,
+            abort() function. By default it both
+            terminates the process and generates a core
+            dump.
+
+            errno=EINTR
+
+ SIGTERM -  This is the default signal that the UN*X
+            kill command sends to processes.
+
+            errno=EINTR
+.fi
+.sp
+Note that in the case of all of the above signals, POSIX mandates that
+by default the process is terminated, with the addition of a core dump
+in the case of the \f3SIGQUIT\f1 signal. In other words, if the
+calling application doesn't override the default handler by supplying
+its own signal handler, receipt of the corresponding signal will
+terminate the application before \f3gl_get_line()\f1 returns.
+.sp
+If gl_get_line() aborts with errno set to EINTR, you can find out what
+signal caused it to abort, by calling the following function.
+.sp
+.nf
+  int gl_last_signal(const GetLine *gl);
+.fi
+.sp
+This returns the numeric code (eg. \f3SIGINT\f1) of the last signal
+that was received during the most recent call to \f3gl_get_line()\f1,
+or \f3-1\f1 if no signals were received.
+.sp
+On systems that support it, when a SIGWINCH (window change) signal is
+received, \f3gl_get_line()\f1 queries the terminal to find out its new
+size, redraws the current input line to accomodate the new size, then
+returns to waiting for keyboard input from the user. Unlike other
+signals, this signal isn't resent to the application.
+.sp
+Finally, the following signals cause \f3gl_get_line()\f1 to first
+restore the terminal and signal environment to that which prevailed
+before \f3gl_get_line()\f1 was called, then resend the signal to the
+application. If the process still exists after the signal has been
+delivered, then \f3gl_get_line()\f1 then re-establishes its own signal
+handlers, switches the terminal back to raw mode, redisplays the input
+line, and goes back to awaiting terminal input from the user.
+.sp
+.nf
+ SIGCONT    -  This signal is generated when a suspended
+               process is resumed.
+
+ SIGPWR     -  This signal is generated when a power failure
+               occurs (presumably when the system is on a
+               UPS).
+
+ SIGALRM    -  This signal is generated when a timer
+               expires.
+
+ SIGUSR1    -  An application specific signal.
+
+ SIGUSR2    -  Another application specific signal.
+
+ SIGVTALRM  -  This signal is generated when a virtual
+               timer expires (see man setitimer(2)).
+
+ SIGXCPU    -  This signal is generated when a process
+               exceeds its soft CPU time limit.
+
+ SIGTSTP    -  This signal is generated by the terminal
+               suspend key, which is usually ^Z, or the
+               delayed terminal suspend key, which is
+               usually ^Y.
+
+ SIGTTIN    -  This signal is generated if the program
+               attempts to read from the terminal while the
+               program is running in the background.
+
+ SIGTTOU    -  This signal is generated if the program
+               attempts to write to the terminal while the
+               program is running in the background.

+Obviously not all of the above signals are supported on all systems,
+so code to support them is conditionally compiled into the tecla
+library.
+.sp
+Note that if \f3SIGKILL\f1, which by definition can't be caught, or
+any of the hardware generated exception signals, such as
+\f3SIGSEGV\f1, \f3SIGBUS\f1 and \f3SIGFPE\f1, are received and
+unhandled while \f3gl_get_line()\f1 has the terminal in raw mode, the
+program will be terminated without the terminal having been restored
+to a usable state. In practice, job-control shells usually reset the
+terminal settings when a process relinquishes the controlling
+terminal, so this is only a problem with older shells.
+
+.SH CUSTOMIZED SIGNAL HANDLING
+
+The previous section listed the signals that
+\f3gl_get_line()\f1 traps by default, and described how it
+responds to them. This section describes how to both add and
+remove signals from the list of trapped signals, and how to
+specify how \f3gl_get_line()\f1 should respond to a given
+signal.
+.sp
+If you don't need \f3gl_get_line()\f1 to do anything in
+response to a signal that it normally traps, you can tell to
+\f3gl_get_line()\f1 to ignore that signal by calling
+\f3gl_ignore_signal()\f1.
+.sp
+.nf
+  int gl_ignore_signal(GetLine *gl, int signo);
+.fi
+.sp
+The \f3signo\f1 argument is the number of the signal
+(eg. \f3SIGINT\f1) that you want to have ignored. If the
+specified signal isn't currently one of those being trapped,
+this function does nothing.
+.sp
+The \f3gl_trap_signal()\f1 function allows you to either add
+a new signal to the list that \f3gl_get_line()\f1 traps, or
+modify how it responds to a signal that it already traps.
+.sp
+.nf
+  int gl_trap_signal(GetLine *gl, int signo, unsigned flags,
+                     GlAfterSignal after, int errno_value);
+.fi
+.sp
+The \f3signo\f1 argument is the number of the signal that
+you wish to have trapped. The \f3flags\f1 argument is a set
+of flags which determine the environment in which the
+application's signal handler is invoked, the \f3after\f1
+argument tells \f3gl_get_line()\f1 what to do after the
+application's signal handler returns, and \f3errno_value\f1
+tells \f3gl_get_line()\f1 what to set \f3errno\f1 to if told
+to abort.
+.sp
+The \f3flags\f1 argument is a bitwise OR of zero or more of
+the following enumerators:
+.sp
+.nf
+  GLS_RESTORE_SIG  -  Restore the caller's signal
+                      environment while handling the
+                      signal.
+
+  GLS_RESTORE_TTY  -  Restore the caller's terminal settings
+                      while handling the signal.
+
+  GLS_RESTORE_LINE -  Move the cursor to the start of the
+                      line following the input line before
+                      invoking the application's signal
+                      handler.
+
+  GLS_REDRAW_LINE  -  Redraw the input line when the
+                      application's signal handler returns.
+
+  GLS_UNBLOCK_SIG  -  Normally, if the calling program has
+                      a signal blocked (man sigprocmask),
+                      gl_get_line() does not trap that
+                      signal. This flag tells gl_get_line()
+                      to trap the signal and unblock it for
+                      the duration of the call to
+                      gl_get_line().
+
+  GLS_DONT_FORWARD -  If this flag is included, the signal
+                      will not be forwarded to the signal
+                      handler of the calling program.
+.fi
+.sp
+Two commonly useful flag combinations are also enumerated as
+follows:
+.sp
+.nf
+  GLS_RESTORE_ENV   = GLS_RESTORE_SIG | GLS_RESTORE_TTY |
+                      GLS_REDRAW_LINE
+
+  GLS_SUSPEND_INPUT = GLS_RESTORE_ENV | GLS_RESTORE_LINE
+.fi
+.sp
+
+If your signal handler, or the default system signal
+handler for this signal, if you haven't overriden it, never
+either writes to the terminal, nor suspends or terminates
+the calling program, then you can safely set the \f3flags\f1
+argument to \f30\f1.
+.sp
+If your signal handler always writes to the terminal, reads
+from it, or suspends or terminates the program, you should
+specify the \f3flags\f1 argument as \f3GL_SUSPEND_INPUT\f1,
+so that:
+.sp
+.nf
+1. The cursor doesn't get left in the middle of the input
+   line.
+2. So that the user can type in input and have it echoed.
+3. So that you don't need to end each output line with
+   \f3\\r\\n\f1, instead of just \f3\\n\f1.
+.fi
+.sp
+The \f3GL_RESTORE_ENV\f1 combination is the same as
+\f3GL_SUSPEND_INPUT\f1, except that it doesn't move the
+cursor, and if your signal handler doesn't read or write
+anything to the terminal, the user won't see any visible
+indication that a signal was caught. This can be useful if
+you have a signal handler that only occasionally writes to
+the terminal, where using \f3GL_SUSPEND_LINE\f1 would cause
+the input line to be unnecessarily duplicated when nothing
+had been written to the terminal.  Such a signal handler,
+when it does write to the terminal, should be sure to start
+a new line at the start of its first write, by writing a
+'\\n' character, and should be sure to leave the cursor on a
+new line before returning. If the signal arrives while the
+user is entering a line that only occupies a signal terminal
+line, or if the cursor is on the last terminal line of a
+longer input line, this will have the same effect as
+\f3GL_SUSPEND_INPUT\f1. Otherwise it will start writing on a
+line that already contains part of the displayed input line.
+This doesn't do any harm, but it looks a bit ugly, which is
+why the \f3GL_SUSPEND_INPUT\f1 combination is better if you
+know that you are always going to be writting to the
+terminal.
+.sp
+The \f3after\f1 argument, which determines what
+\f3gl_get_line()\f1 does after the application's signal
+handler returns (if it returns), can take any one of the
+following values:
+.sp
+.nf
+  GLS_RETURN   - Return the completed input line, just as
+                 though the user had pressed the return
+                 key.
+
+  GLS_ABORT    - Cause gl_get_line() to return \f3NULL\f1.
+
+  GLS_CONTINUE - Resume command line editing. 
+.fi
+.sp
+The \f3errno_value\f1 argument is intended to be combined
+with the \f3GLS_ABORT\f1 option, telling \f3gl_get_line()\f1
+what to set the standard \f3errno\f1 variable to before
+returning \f3NULL\f1 to the calling program. It can also,
+however, be used with the \f3GL_RETURN\f1 option, in case
+you wish to have a way to distinguish between an input line
+that was entered using the return key, and one that was
+entered by the receipt of a signal.
+
+.SH THE TERMINAL SIZE
+
+On most systems the combination of the \f3TIOCGWINSZ\f1 ioctl and the
+\f3SIGWINCH\f1 signal is used to maintain an accurate idea of the
+terminal size. The terminal size is newly queried every time that
+\f3gl_get_line()\f1 is called and whenever a \f3SIGWINCH\f1 signal is
+received.
+.sp
+On the few systems where this mechanism isn't available, at
+startup \f3new_GetLine()\f1 first looks for the \f3LINES\f1
+and \f3COLUMNS\f1 environment variables.  If these aren't
+found, or they contain unusable values, then if a terminal
+information database like terminfo or termcap is available,
+the default size of the terminal is looked up in this
+database. If this too fails to provide the terminal size, a
+default size of 80 columns by 24 lines is used. If this
+default isn't appropriate for your system,
+\f3gl_terminal_size()\f1 can be used to supply a different
+fallback.
+.sp
+The \f3gl_terminal_size()\f1 function allows you to query
+the current size of the terminal, and install an alternate
+fallback size for cases where the size isn't available.
+Beware that the terminal size won't be available if reading
+from a pipe or a file, so the default values can be
+important even on systems that do support ways of finding
+out the terminal size.
+.sp
+.nf
+  typedef struct {
+    int nline;        /* The terminal has nline lines */
+    int ncolumn;      /* The terminal has ncolumn columns */
+  } GlTerminalSize;
+
+  GlTerminalSize gl_terminal_size(GetLine *gl,
+                                  int def_ncolumn,
+                                  int def_nline);
+.fi
+.sp
+This function first updates \f3gl_get_line()\f1's idea of
+the terminal size, then records its findings in the return
+value.
+.sp
+The \f3def_ncolumn\f1 and \f3def_nline\f1 specify the
+default number of terminal columns and lines to use if the
+terminal size can't be determined.
+
+.SH HIDING WHAT YOU TYPE
+
+When entering sensitive information, such as passwords, it is best not
+to have the text that you are entering echoed on the terminal.
+Furthermore, such text should not be recorded in the history list,
+since somebody finding your terminal unattended could then recall it,
+or somebody snooping through your directories could see it in your
+history file. With this in mind, the \f3gl_echo_mode()\f1
+function allows you to toggle on and off the display and archival of
+any text that is subsequently entered in calls to \f3gl_get_line()\f1.
+
+.sp
+.nf
+  int gl_echo_mode(GetLine *gl, int enable);
+.fi
+.sp
+
+The \f3enable\f1 argument specifies whether entered text
+should be visible or not. If it is \f30\f1, then
+subsequently entered lines will not be visible on the
+terminal, and will not be recorded in the history list. If
+it is \f31\f1, then subsequent input lines will be displayed
+as they are entered, and provided that history hasn't been
+turned off via a call to \f3gl_toggle_history()\f1, then
+they will also be archived in the history list. Finally, if
+the \f3enable\f1 argument is \f3-1\f1, then the echoing mode
+is left unchanged, which allows you to non-destructively
+query the current setting via the return value. In all
+cases, the return value of the function is \f30\f1 if
+echoing was disabled before the function was called, and
+\f31\f1 if it was enabled.
+.sp
+When echoing is turned off, note that although tab
+completion will invisibly complete your prefix as far as
+possible, ambiguous completions will not be displayed.
+
+.SH CALLBACK FUNCTION FACILITIES
+
+Unless otherwise stated, callback functions, such as tab
+completion callbacks and event callbacks should not call any
+functions in this module. The following functions, however,
+are designed specifically to be used by callback functions.
+.sp
+Calling the \f3gl_replace_prompt()\f1 function from a
+callback tells \f3gl_get_line() to display a different
+prompt when the callback returns. It has no effect if called
+when \f3gl_get_line()\f1 is not being called.
+.sp
+.nf
+  void gl_replace_prompt(GetLine *gl, const char *prompt);
+.fi
+.sp
+
+.SH INTERNATIONAL CHARACTER SETS
+
+Since libtecla version 1.4.0, \f3gl_get_line()\f1 has been 8-bit
+clean. This means that all 8-bit characters that are printable in the
+user's current locale are now displayed verbatim and included in the
+returned input line.  Assuming that the calling program correctly
+contains a call like the following,
+.sp
+.nf
+  setlocale(LC_CTYPE, "");
+.fi
+.sp
+then the current locale is determined by the first of the environment
+variables \f3LC_CTYPE\f1, \f3LC_ALL\f1, and \f3LANG\f1, that is found
+to contain a valid locale name. If none of these variables are
+defined, or the program neglects to call setlocale, then the default
+\f3C\f1 locale is used, which is US 7-bit ASCII. On most unix-like
+platforms, you can get a list of valid locales by typing the command:
+.sp
+.nf
+  locale -a
+.fi
+.sp
+at the shell prompt.
+.sp
+.SS "Meta keys and locales"
+
+Beware that in most locales other than the default C locale, meta
+characters become printable, and they are then no longer considered to
+match \f3M-c\f1 style key bindings. This allows international
+characters to be entered with the compose key without unexpectedly
+triggering meta key bindings. You can still invoke meta bindings,
+since there are actually two ways to do this. For example the binding
+\f3M-c\f1 can also be invoked by pressing the escape key momentarily,
+then pressing the \f3c\f1 key, and this will work regardless of
+locale. Moreover, many modern terminal emulators, such as gnome's
+gnome-terminal's and KDE's konsole terminals, already generate escape
+pairs like this when you use the meta key, rather than a real meta
+character, and other emulators usually have a way to request this
+behavior, so you can continue to use the meta key on most systems.
+.sp
+For example, although xterm terminal emulators generate real 8-bit
+meta characters by default when you use the meta key, they can be
+configured to output the equivalent escape pair by setting their
+\f3EightBitInput\f1 X resource to \f3False\f1. You can either do this
+by placing a line like the following in your \f3~/.Xdefaults\f1 file,
+.sp
+.nf
+  XTerm*EightBitInput: False
+.sp
+.fi
+or by starting an xterm with an \f3-xrm '*EightBitInput: False'\f1
+command-line argument. In recent versions of xterm you can toggle this
+feature on and off with the \f3"Meta Sends Escape"\f1 option in the
+menu that is displayed when you press the left mouse button and the
+control key within an xterm window. In CDE, dtterms can be similarly
+coerced to generate escape pairs in place of meta characters, by
+setting the \f3Dtterm*KshMode\f1 resource to \f3True\f1.
+.sp
+.SS "Entering international characters"
+
+If you don't have a keyboard that generates all of the international
+characters that you need, there is usually a compose key that will
+allow you to enter special characters, or a way to create one. For
+example, under X windows on unix-like systems, if your keyboard
+doesn't have a compose key, you can designate a redundant key to serve
+this purpose with the xmodmap command. For example, on many PC
+keyboards there is a microsoft-windows key, which is otherwise useless
+under Linux. On my PC the \f3xev\f1 program reports that pressing this
+key generates keycode 115, so to turn this key into a compose key, I
+do the following:
+.sp
+.nf
+  xmodmap -e 'keycode 115 = Multi_key'
+.fi
+.sp
+I can then enter an i with a umlaut over it by typing this key,
+followed by \f3"\f1, followed by i.
+
+.SH THREAD SAFETY
+
+In a multi-threaded program, you should use the libtecla_r.a version
+of the library. This uses reentrant versions of system functions,
+where available. Unfortunately neither terminfo nor termcap were
+designed to be reentrant, so you can't safely use the functions of the
+getline module in multiple threads (you can use the separate
+file-expansion and word-completion modules in multiple threads, see
+the corresponding man pages for details). However due to the use of
+POSIX reentrant functions for looking up home directories etc, it is
+safe to use this module from a single thread of a multi-threaded
+program, provided that your other threads don't use any termcap or
+terminfo functions.

+.SH NAME
+libtecla - An interactive command-line input library.
+.SH SYNOPSIS
+.nf
+gcc ... -ltecla -lcurses
+.fi
+
+.SH DESCRIPTION
+
+The \f3tecla\f1 library provides programs with interactive command
+line editing facilities, similar to those of the unix \f3tcsh\f1
+shell. In addition to simple command-line editing, it supports recall
+of previously entered command lines, TAB completion of file names or
+other tokens, and in-line wild-card expansion of filenames. The
+internal functions which perform file-name completion and wild-card
+expansion are also available externally for optional use by the
+calling program.
+.sp
+The various parts of the library are documented in the following man
+pages:
+
+.nf
+  gl_get_line(3)        -  The interactive line-input module.
+  cpl_complete_word(3)  -  The word completion module.
+  ef_expand_file(3)     -  The filename expansion module.
+  pca_lookup_file(3)    -  A directory-list based filename
+                           lookup and completion module.
+.fi
+
+In addition there is one optional application distributed
+with the library:
+
+.nf
+  enhance(3)            -  Add command-line editing to third
+                           party applications.
+.fi
+
+.SH THREAD SAFETY
+
+If the library is compiled with -D_POSIX_C_SOURCE=199506L, reentrant
+versions of as many functions as possible are used. This includes
+using getpwuid_r() and getpwnam_r() instead of getpwuid() and
+getpwnam() when looking up the home directories of specific users in
+the password file (for ~user/ expansion), and readdir_r() instead of
+readdir() for reading directory entries when doing filename
+completion. The reentrant version of the library is usually called
+libtecla_r.a instead of libtecla.a, so if only the latter is
+available, it probably isn't the correct version to link with
+threaded programs.
+
+Reentrant functions for iterating through the password file aren't
+available, so when the library is compiled to be reentrant, TAB
+completion of incomplete usernames in \f3~username/\f1 expressions is
+disabled. This doesn't disable expansion of complete \f3~username\f1
+expressions, which can be done reentrantly, or expansion of the parts
+of filenames that follow them, so this doesn't remove much
+functionality.
+
+The terminfo functions setupterm(), tigetstr(), tigetnum() and tputs()
+also aren't reentrant, but very few programs will want to interact
+with multiple terminals, so this shouldn't prevent this library from
+being used in threaded programs.
+
+.SH LIBRARY VERSION NUMBER
+
+The version number of the library can be queried using the following
+function.
+.sp
+.nf
+ void libtecla_version(int *major, int *minor, int *micro);
+.fi
+.sp
+
+On return, this function records the three components of the libtecla
+version number in \f3*major\f1, \f3*minor\f1, \f3*micro\f1. The formal
+meaning of the three components is as follows.
+
+.sp
+.nf
+ major - Incrementing this number implies that a change has
+         been made to the library's public interface, which
+         makes it binary incompatible  with programs that
+         were linked with previous shared versions of the
+         tecla library.
+
+ minor - This number is incremented by one whenever
+         additional functionality, such as new functions or
+         modules, are added to the library.
+
+ micro - This is incremented whenever modifications to the
+         library are made which make no changes to the
+         public interface, but which fix bugs and/or improve
+         the behind-the-scenes implementation.
+.fi
+.sp
+
+.SH TRIVIA
+
+In Spanish, a "tecla" is the key of a keyboard. Since this library
+centers on keyboard input, and given that I wrote much of the library
+while working in Chile, this seemed like a suitable name.

+
+.SH DESCRIPTION
+
+The \f3PathCache\f1 object is part of the tecla library (see the
+libtecla(3) man page).
+.sp
+\f3PathCache\f1 objects allow an application to search for files in
+any colon separated list of directories, such as the unix execution
+PATH environment variable. Files in absolute directories are cached in
+a \f3PathCache\f1 object, whereas relative directories are scanned as
+needed. Using a \f3PathCache\f1 object, you can look up the full
+pathname of a simple filename, or you can obtain a list of the
+possible completions of a given filename prefix. By default all files
+in the list of directories are targets for lookup and completion, but
+a versatile mechanism is provided for only selecting specific types of
+files. The obvious application of this facility is to provide
+Tab-completion and lookup of executable commands in the unix PATH, so
+an optional callback which rejects all but executable files, is
+provided.
+.sp
+.SH AN EXAMPLE
+
+Under UNIX, the following example program looks up and displays the
+full pathnames of each of the command names on the command line.
+.sp
+.nf
+  #include <stdio.h>
+  #include <stdlib.h>
+  #include <libtecla.h>
+
+  int main(int argc, char *argv[])
+  {
+    int i;
+  /*
+   * Create a cache for executable files.
+   */
+    PathCache *pc = new_PathCache();
+    if(!pc)
+      exit(1);
+  /*
+   * Scan the user's PATH for executables.
+   */
+    if(pca_scan_path(pc, getenv("PATH"))) {
+      fprintf(stderr, "%s\\n", pca_last_error(pc));
+      exit(1);
+    }
+  /*
+   * Arrange to only report executable files.
+   */
+   pca_set_check_fn(pc, cpl_check_exe, NULL);
+  /*
+   * Lookup and display the full pathname of each of the
+   * commands listed on the command line.
+   */
+    for(i=1; i<argc; i++) {
+      char *cmd = pca_lookup_file(pc, argv[i], -1, 0);
+      printf("The full pathname of '%s' is %s\\n", argv[i],
+             cmd ? cmd : "unknown");
+    }
+    pc = del_PathCache(pc);  /* Clean up */
+    return 0;
+  }
+.fi
+.sp
+The following is an example of what this does on my laptop under
+linux:
+.sp
+.nf
+  $ ./example less more blob
+  The full pathname of 'less' is /usr/bin/less
+  The full pathname of 'more' is /bin/more
+  The full pathname of 'blob' is unknown
+  $ 
+.fi
+.sp
+.SH FUNCTION DESCRIPTIONS
+
+In order to use the facilities of this module, you must first allocate
+a \f3PathCache\f1 object by calling the \f3new_PathCache()\f1
+constructor function.
+.sp
+.nf
+  PathCache *new_PathCache(void)
+.fi
+.sp
+This function creates the resources needed to cache and lookup files
+in a list of directories. It returns \f3NULL\f1 on error.
+.sp
+.SH POPULATING THE CACHE
+Once you have created a cache, it needs to be populated with files.
+To do this, call the \f3pca_scan_path()\f1 function.
+.sp
+.nf
+  int pca_scan_path(PathCache *pc, const char *path);
+.fi
+.sp
+Whenever this function is called, it discards the current contents of
+the cache, then scans the list of directories specified in its
+\f3path\f1 argument for files. The \f3path\f1 argument must be a
+string containing a colon-separated list of directories, such as
+\f3"/usr/bin:/home/mcs/bin:."\f1. This can include directories
+specified by absolute pathnames such as \f3"/usr/bin"\f1, as well as
+sub-directories specified by relative pathnames such as \f3"."\f1 or
+\f3"bin"\f1. Files in the absolute directories are immediately cached
+in the specified \f3PathCache\f1 object, whereas sub-directories,
+whose identities obviously change whenever the current working
+directory is changed, are marked to be scanned on the fly whenever a
+file is looked up.
+.sp
+On success this function return \f30\f1. On error it returns \f31\f1,
+and a description of the error can be obtained by calling
+\f3pca_last_error(pc)\f1.
+.sp
+.SH LOOKING UP FILES
+
+Once the cache has been populated with files, you can look up the full
+pathname of a file, simply by specifying its filename to
+\f3pca_lookup_file()\f1.
+.sp
+.nf
+  char *pca_lookup_file(PathCache *pc, const char *name,
+                        int name_len, int literal);
+.fi
+.sp
+To make it possible to pass this function a filename which is actually
+part of a longer string, the \f3name_len\f1 argument can be used to
+specify the length of the filename at the start of the \f3name[]\f1
+argument. If you pass \f3-1\f1 for this length, the length of the
+string will be determined with \f3strlen()\f1. If the \f3name[]\f1
+string might contain backslashes that escape the special meanings of
+spaces and tabs within the filename, give the \f3literal\f1 argument,
+the value \f30\f1. Otherwise, if backslashes should be treated as
+normal characters, pass \f31\f1 for the value of the \f3literal\f1
+argument.
+
+.SH FILENAME COMPLETION
+
+Looking up the potential completions of a filename-prefix in the
+filename cache, is achieved by passing the provided
+\f3pca_path_completions()\f1 callback function to the
+\f3cpl_complete_word()\f1 function (see the \f3cpl_complete_word(3)\f1
+man page).
+.sp
+.nf
+  CPL_MATCH_FN(pca_path_completions);
+.fi
+.sp
+This callback requires that its \f3data\f1 argument be a pointer to a
+\f3PcaPathConf\f1 object. Configuration objects of this type are
+allocated by calling \f3new_PcaPathConf()\f1.
+.sp
+.nf
+  PcaPathConf *new_PcaPathConf(PathCache *pc);
+.fi
+.sp
+This function returns an object initialized with default configuration
+parameters, which determine how the \f3cpl_path_completions()\f1
+callback function behaves. The functions which allow you to
+individually change these parameters are discussed below.
+.sp
+By default, the \f3pca_path_completions()\f1 callback function
+searches backwards for the start of the filename being completed,
+looking for the first un-escaped space or the start of the input
+line. If you wish to specify a different location, call
+\f3ppc_file_start()\f1 with the index at which the filename starts in
+the input line. Passing \f3start_index=-1\f1 re-enables the default
+behavior.
+.sp
+.nf
+  void ppc_file_start(PcaPathConf *ppc, int start_index);
+.fi
+.sp
+By default, when \f3pca_path_completions()\f1 looks at a filename in
+the input line, each lone backslash in the input line is interpreted
+as being a special character which removes any special significance of
+the character which follows it, such as a space which should be taken
+as part of the filename rather than delimiting the start of the
+filename. These backslashes are thus ignored while looking for
+completions, and subsequently added before spaces, tabs and literal
+backslashes in the list of completions. To have unescaped backslashes
+treated as normal characters, call \f3ppc_literal_escapes()\f1 with a
+non-zero value in its \f3literal\f1 argument.
+.sp
+.nf
+  void ppc_literal_escapes(PcaPathConf *ppc, int literal);
+.fi
+.sp
+When you have finished with a \f3PcaPathConf\f1 variable, you can pass
+it to the \f3del_PcaPathConf()\f1 destructor function to reclaim its
+memory.
+.sp
+.nf
+  PcaPathConf *del_PcaPathConf(PcaPathConf *ppc);
+.fi
+.sp
+
+.SH BEING SELECTIVE
+If you are only interested in certain types or files, such as, for
+example, executable files, or files whose names end in a particular
+suffix, you can arrange for the file completion and lookup functions
+to be selective in the filenames that they return.  This is done by
+registering a callback function with your \f3PathCache\f1
+object. Thereafter, whenever a filename is found which either matches
+a filename being looked up, or matches a prefix which is being
+completed, your callback function will be called with the full
+pathname of the file, plus any application-specific data that you
+provide, and if the callback returns \f31\f1 the filename will be
+reported as a match, and if it returns \f30\f1, it will be ignored.
+Suitable callback functions and their prototypes should be declared
+with the following macro. The \f3CplCheckFn\f1 \f3typedef\f1 is also
+provided in case you wish to declare pointers to such functions.
+.sp
+.nf
+  #define CPL_CHECK_FN(fn) int (fn)(void *data, \\
+                                    const char *pathname)
+  typedef CPL_CHECK_FN(CplCheckFn);
+.fi
+.sp
+Registering one of these functions involves calling the
+\f3pca_set_check_fn()\f1 function. In addition to the callback
+function, passed via the \f3check_fn\f1 argument, you can pass a
+pointer to anything via the \f3data\f1 argument. This pointer will be
+passed on to your callback function, via its own \f3data\f1 argument,
+whenever it is called, so this provides a way to pass appplication
+specific data to your callback.
+.sp
+.nf
+  void pca_set_check_fn(PathCache *pc, CplCheckFn *check_fn,
+                        void *data);
+.fi
+.sp
+Note that these callbacks are passed the full pathname of each
+matching file, so the decision about whether a file is of interest can
+be based on any property of the file, not just its filename. As an
+example, the provided \f3cpl_check_exe()\f1 callback function looks at
+the executable permissions of the file and the permissions of its
+parent directories, and only returns \f31\f1 if the user has execute
+permission to the file. This callback function can thus be used to
+lookup or complete command names found in the directories listed in
+the user's \f3PATH\f1 environment variable. The example program given
+earlier in this man page provides a demonstration of this.
+.sp
+Beware that if somebody tries to complete an empty string, your
+callback will get called once for every file in the cache, which could
+number in the thousands. If your callback does anything time
+consuming, this could result in an unacceptable delay for the user, so
+callbacks should be kept short.
+.sp
+To improve performance, whenever one of these callbacks is called, the
+choice that it makes is cached, and the next time the corresponding
+file is looked up, instead of calling the callback again, the cached
+record of whether it was accepted or rejected is used. Thus if
+somebody tries to complete an empty string, and hits tab a second time
+when nothing appears to happen, there will only be one long delay,
+since the second pass will operate entirely from the cached
+dispositions of the files. These cached dipositions are discarded
+whenever \f3pca_scan_path()\f1 is called, and whenever
+\f3pca_set_check_fn()\f1 is called with changed callback function or
+data arguments.
+
+.SH ERROR HANDLING
+
+If \f3pca_scan_path()\f1 reports that an error occurred by returning
+\f31\f1, you can obtain a terse description of the error by calling
+\f3pca_last_error(pc)\f1. This returns an internal string containing
+an error message.
+.sp
+.nf
+  const char *pca_last_error(PathCache *pc);
+.fi
+.sp
+
+.SH CLEANING UP
+
+Once you have finished using a \f3PathCache\f1 object, you can reclaim
+its resources by passing it to the \f3del_PathCache()\f1 destructor
+function. This takes a pointer to one of these objects, and always
+returns \f3NULL\f1.
+.sp
+.nf
+  PathCache *del_PathCache(PathCache *pc);
+.fi
+.sp
+.SH THREAD SAFETY
+
+In multi-threaded programs, you should use the \f3libtecla_r.a\f1
+version of the library. This uses POSIX reentrant functions where
+available (hence the \f3_r\f1 suffix), and disables features that rely
+on non-reentrant system functions. In the case of this module, the
+only disabled feature is username completion in \f3~username/\f1
+expressions, in \f3cpl_path_completions()\f1.
+
+Using the \f3libtecla_r.a\f1 version of the library, it is safe to use
+the facilities of this module in multiple threads, provided that each
+thread uses a separately allocated \f3PathCache\f1 object. In other
+words, if two threads want to do path searching, they should each call
+\f3new_PathCache()\f1 to allocate their own caches.

-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

-The History library provides a history expansion feature that is similar
-to the history expansion provided by <CODE>csh</CODE>.  This section
-describes the syntax used to manipulate the history information.
-
-</P>
-<P>
-History expansions introduce words from the history list into
-the input stream, making it easy to repeat commands, insert the
-arguments to a previous command into the current input line, or
-fix errors in previous commands quickly.
-
-</P>
-<P>
-History expansion takes place in two parts.  The first is to determine
-which line from the history list should be used during substitution.
-The second is to select portions of that line for inclusion into the
-current one.  The line selected from the history is called the
-<EM>event</EM>, and the portions of that line that are acted upon are
-called <EM>words</EM>.  Various <EM>modifiers</EM> are available to manipulate
-the selected words.  The line is broken into words in the same fashion
-that Bash does, so that several words
-surrounded by quotes are considered one word.
-History expansions are introduced by the appearance of the
-history expansion character, which is <SAMP>`!'</SAMP> by default.

-
-<P>
-The following paragraphs describe the notation used to represent
-keystrokes.
-
-</P>
-<P>
-The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
-produced when the <KBD>k</KBD> key is pressed while the Control key
-is depressed.
-
-</P>
-<P>
-The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
-key is pressed.
-The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
-On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
-the space bar), the <KBD>ALT</KBD> on the left side is generally set to
-work as a Meta key.
-The <KBD>ALT</KBD> key on the right may also be configured to work as a
-Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-</P>
-<P>
-If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
-a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
-<EM>first</EM>, and then typing <KBD>k</KBD>.
-Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
-
-</P>
-<P>
-The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
-character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
-
-</P>
-<P>
-In addition, several keys have their own names.  Specifically,
-<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
-stand for themselves when seen in this text, or in an init file
-(see section <A HREF="readline.html#SEC9">Readline Init File</A>).
-If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
-produce the desired character.
-The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
-some keyboards.

-Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled.  The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line.  Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections.  Then, when you are satisfied with
-the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
-end of the line to press <KBD>RET</KBD>; the entire line is accepted
-regardless of the location of the cursor within the line.

-In order to enter characters into the line, simply type them.  The typed
-character appears where the cursor was, and then the cursor moves one
-space to the right.  If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
-</P>
-<P>
-Sometimes you may mistype a character, and
-not notice the error until you have typed several other characters.  In
-that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
-correct your mistake.  Afterwards, you can move the cursor to the right
-with <KBD>C-f</KBD>.
-
-</P>
-<P>
-When you add text in the middle of a line, you will notice that characters
-to the right of the cursor are `pushed over' to make room for the text
-that you have inserted.  Likewise, when you delete text behind the cursor,
-characters to the right of the cursor are `pulled back' to fill in the
-blank space created by the removal of the text.  A list of the bare
-essentials for editing the text of an input line follows.

-
-<P>
-(Depending on your configuration, the <KBD>Backspace</KBD> key be set to
-delete the character to the left of the cursor and the <KBD>DEL</KBD> key set
-to delete the character underneath the cursor, like <KBD>C-d</KBD>, rather
-than the character to the left of the cursor.)

-
-<P>
-The above table describes the most basic keystrokes that you need
-in order to do editing of the input line.  For your convenience, many
-other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
-<KBD>C-d</KBD>, and <KBD>DEL</KBD>.  Here are some commands for moving more rapidly
-about the line.
-
-</P>
-<DL COMPACT>
-
-<DT><KBD>C-a</KBD>
-<DD>
-Move to the start of the line.
-<DT><KBD>C-e</KBD>
-<DD>
-Move to the end of the line.
-<DT><KBD>M-f</KBD>
-<DD>
-Move forward a word, where a word is composed of letters and digits.
-<DT><KBD>M-b</KBD>
-<DD>
-Move backward a word.
-<DT><KBD>C-l</KBD>
-<DD>
-Clear the screen, reprinting the current line at the top.
-</DL>
-
-<P>
-Notice how <KBD>C-f</KBD> moves forward a character, while <KBD>M-f</KBD> moves
-forward a word.  It is a loose convention that control keystrokes
-operate on characters while meta keystrokes operate on words.

-</P>
-<P>
-<EM>Killing</EM> text means to delete the text from the line, but to save
-it away for later use, usually by <EM>yanking</EM> (re-inserting)
-it back into the line.
-(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
-
-</P>
-<P>
-If the description for a command says that it `kills' text, then you can
-be sure that you can get the text back in a different (or the same)
-place later.
-
-</P>
-<P>
-When you use a kill command, the text is saved in a <EM>kill-ring</EM>.
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all.  The kill
-ring is not line specific; the text that you killed on a previously
-typed line is available to be yanked back later, when you are typing
-another line.

-Here is the list of commands for killing text.
-
-</P>
-<DL COMPACT>
-
-<DT><KBD>C-k</KBD>
-<DD>
-Kill the text from the current cursor position to the end of the line.
-
-<DT><KBD>M-d</KBD>
-<DD>
-Kill from the cursor to the end of the current word, or, if between
-words, to the end of the next word.
-Word boundaries are the same as those used by <KBD>M-f</KBD>.
-
-<DT><KBD>M-<KBD>DEL</KBD></KBD>
-<DD>
-Kill from the cursor the start of the previous word, or, if between
-words, to the start of the previous word.
-Word boundaries are the same as those used by <KBD>M-b</KBD>.
-
-<DT><KBD>C-w</KBD>
-<DD>
-Kill from the cursor to the previous whitespace.  This is different than
-<KBD>M-<KBD>DEL</KBD></KBD> because the word boundaries differ.
-
-</DL>
-
-<P>
-Here is how to <EM>yank</EM> the text back into the line.  Yanking
-means to copy the most-recently-killed text from the kill buffer.
-
-</P>
-<DL COMPACT>
-
-<DT><KBD>C-y</KBD>
-<DD>
-Yank the most recently killed text back into the buffer at the cursor.
-
-<DT><KBD>M-y</KBD>
-<DD>
-Rotate the kill-ring, and yank the new top.  You can only do this if
-the prior command is <KBD>C-y</KBD> or <KBD>M-y</KBD>.
-</DL>
-
-
-
-<H3><A NAME="SEC7" HREF="readline.html#TOC7">Readline Arguments</A></H3>
-
-<P>
-You can pass numeric arguments to Readline commands.  Sometimes the
-argument acts as a repeat count, other times it is the <I>sign</I> of the
-argument that is significant.  If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction.  For example, to kill text back to the
-start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
-
-</P>
-<P>
-The general way to pass numeric arguments to a command is to type meta
-digits before the command.  If the first `digit' typed is a minus
-sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
-you have typed one meta digit to get the argument started, you can type
-the remainder of the digits, and then the command.  For example, to give
-the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
-which will delete the next ten characters on the input line.
-
-</P>
-
-
-<H3><A NAME="SEC8" HREF="readline.html#TOC8">Searching for Commands in the History</A></H3>
-
-<P>
-Readline provides commands for searching through the command history
-for lines containing a specified string.
-There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
-
-</P>
-<P>
-Incremental searches begin before the user has finished typing the
-search string.
-As each character of the search string is typed, Readline displays
-the next entry from the history matching the string typed so far.
-An incremental search requires only as many characters as needed to
-find the desired history entry.
-To search backward in the history for a particular string, type
-<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
-The characters present in the value of the <CODE>isearch-terminators</CODE> variable
-are used to terminate an incremental search.
-If that variable has not been assigned a value, the <KBD>ESC</KBD> and
-<KBD>C-J</KBD> characters will terminate an incremental search.
-<KBD>C-g</KBD> will abort an incremental search and restore the original line.
-When the search is terminated, the history entry containing the
-search string becomes the current line.
-
-</P>
-<P>
-To find other matching entries in the history list, type <KBD>C-r</KBD> or
-<KBD>C-s</KBD> as appropriate.
-This will search backward or forward in the history for the next
-entry matching the search string typed so far.
-Any other key sequence bound to a Readline command will terminate
-the search and execute that command.
-For instance, a <KBD>RET</KBD> will terminate the search and accept
-the line, thereby executing the command from the history list.
-A movement command will terminate the search, make the last line found
-the current line, and begin editing.
-
-</P>
-<P>
-Non-incremental searches read the entire search string before starting
-to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.

-<P>
-Although the Readline library comes with a set of Emacs-like
-keybindings installed by default, it is possible to use a different set
-of keybindings.
-Any user can customize programs that use Readline by putting
-commands in an <EM>inputrc</EM> file, conventionally in his home directory.
-The name of this
-file is taken from the value of the environment variable @env{INPUTRC}.  If
-that variable is unset, the default is <TT>`~/.inputrc'</TT>.
-
-</P>
-<P>
-When a program which uses the Readline library starts up, the
-init file is read, and the key bindings are set.

-<DT>Variable Settings
-<DD>
-You can modify the run-time behavior of Readline by
-altering the values of variables in Readline
-using the <CODE>set</CODE> command within the init file.
-The syntax is simple:
-
-
-<PRE>
-set <VAR>variable</VAR> <VAR>value</VAR>
-</PRE>
-
-Here, for example, is how to
-change from the default Emacs-like key binding to use
-<CODE>vi</CODE> line editing commands:
-
-
-<PRE>
-set editing-mode vi
-</PRE>
-
-Variable names and values, where appropriate, are recognized without regard
-to case. 
-
-A great deal of run-time behavior is changeable with the following
-variables.
-
-<A NAME="IDX9"></A>
-<DL COMPACT>
-
-<DT><CODE>bell-style</CODE>
-<DD>
-<A NAME="IDX10"></A>
-Controls what happens when Readline wants to ring the terminal bell.
-If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
-<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
-If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
-the terminal's bell.
-
-<DT><CODE>comment-begin</CODE>
-<DD>
-<A NAME="IDX11"></A>
-The string to insert at the beginning of the line when the
-<CODE>insert-comment</CODE> command is executed.  The default value
-is <CODE>"#"</CODE>.
-
-<DT><CODE>completion-ignore-case</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
-in a case-insensitive fashion.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>completion-query-items</CODE>
-<DD>
-<A NAME="IDX12"></A>
-The number of possible completions that determines when the user is
-asked whether he wants to see the list of possibilities.  If the
-number of possible completions is greater than this value,
-Readline will ask the user whether or not he wishes to view
-them; otherwise, they are simply listed.
-This variable must be set to an integer value greater than or equal to 0.
-The default limit is <CODE>100</CODE>.
-
-<DT><CODE>convert-meta</CODE>
-<DD>
-<A NAME="IDX13"></A>
-If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
-eighth bit set to an ASCII key sequence by stripping the eighth
-bit and prefixing an <KBD>ESC</KBD> character, converting them to a
-meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
-
-<DT><CODE>disable-completion</CODE>
-<DD>
-<A NAME="IDX14"></A>
-If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
-Completion  characters will be inserted into the line as if they had
-been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>editing-mode</CODE>
-<DD>
-<A NAME="IDX15"></A>
-The <CODE>editing-mode</CODE> variable controls which default set of
-key bindings is used.  By default, Readline starts up in Emacs editing
-mode, where the keystrokes are most similar to Emacs.  This variable can be
-set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
-
-<DT><CODE>enable-keypad</CODE>
-<DD>
-<A NAME="IDX16"></A>
-When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
-keypad when it is called.  Some systems need this to enable the
-arrow keys.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>expand-tilde</CODE>
-<DD>
-<A NAME="IDX17"></A>
-If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
-attempts word completion.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>horizontal-scroll-mode</CODE>
-<DD>
-<A NAME="IDX18"></A>
-This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
-to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
-horizontally on a single screen line when they are longer than the width
-of the screen, instead of wrapping onto a new screen line.  By default,
-this variable is set to <SAMP>`off'</SAMP>.
-
-<DT><CODE>input-meta</CODE>
-<DD>
-<A NAME="IDX19"></A>
-<A NAME="IDX20"></A>
-If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
-will not clear the eighth bit in the characters it reads),
-regardless of what the terminal claims it can support.  The
-default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
-synonym for this variable.
-
-<DT><CODE>isearch-terminators</CODE>
-<DD>
-<A NAME="IDX21"></A>
-The string of characters that should terminate an incremental search without
-subsequently executing the character as a command (see section <A HREF="readline.html#SEC8">Searching for Commands in the History</A>).
-If this variable has not been given a value, the characters <KBD>ESC</KBD> and
-<KBD>C-J</KBD> will terminate an incremental search.
-
-<DT><CODE>keymap</CODE>
-<DD>
-<A NAME="IDX22"></A>
-Sets Readline's idea of the current keymap for key binding commands.
-Acceptable <CODE>keymap</CODE> names are
-<CODE>emacs</CODE>,
-<CODE>emacs-standard</CODE>,
-<CODE>emacs-meta</CODE>,
-<CODE>emacs-ctlx</CODE>,
-<CODE>vi</CODE>,
-<CODE>vi-move</CODE>,
-<CODE>vi-command</CODE>, and
-<CODE>vi-insert</CODE>.
-<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
-equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
-The value of the <CODE>editing-mode</CODE> variable also affects the
-default keymap.
-
-<DT><CODE>mark-directories</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, completed directory names have a slash
-appended.  The default is <SAMP>`on'</SAMP>.
-
-<DT><CODE>mark-modified-lines</CODE>
-<DD>
-<A NAME="IDX23"></A>
-This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
-asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
-This variable is <SAMP>`off'</SAMP> by default.
-
-<DT><CODE>output-meta</CODE>
-<DD>
-<A NAME="IDX24"></A>
-If set to <SAMP>`on'</SAMP>, Readline will display characters with the
-eighth bit set directly rather than as a meta-prefixed escape
-sequence.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>print-completions-horizontally</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
-sorted horizontally in alphabetical order, rather than down the screen.
-The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>show-all-if-ambiguous</CODE>
-<DD>
-<A NAME="IDX25"></A>
-This alters the default behavior of the completion functions.  If
-set to <SAMP>`on'</SAMP>, 
-words which have more than one possible completion cause the
-matches to be listed immediately instead of ringing the bell.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>visible-stats</CODE>
-<DD>
-<A NAME="IDX26"></A>
-If set to <SAMP>`on'</SAMP>, a character denoting a file's type
-is appended to the filename when listing possible
-completions.  The default is <SAMP>`off'</SAMP>.
-
-</DL>
-
-<DT>Key Bindings
-<DD>
-The syntax for controlling key bindings in the init file is
-simple.  First you need to find the name of the command that you
-want to change.  The following sections contain tables of the command
-name, the default keybinding, if any, and a short description of what
-the command does.
-
-Once you know the name of the command, simply place on a line
-in the init file the name of the key
-you wish to bind the command to, a colon, and then the name of the
-command.  The name of the key
-can be expressed in different ways, depending on what you find most
-comfortable.
-
-In addition to command names, readline allows keys to be bound
-to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
-
-<DL COMPACT>
-
-<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
-
-<PRE>
-Control-u: universal-argument
-Meta-Rubout: backward-kill-word
-Control-o: "&#62; output"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is bound to the function
-<CODE>universal-argument</CODE>,
-<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
-<KBD>C-o</KBD> is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-<SAMP>`&#62; output'</SAMP> into the line).
-
-A number of symbolic character names are recognized while
-processing this key binding syntax:
-<VAR>DEL</VAR>,
-<VAR>ESC</VAR>,
-<VAR>ESCAPE</VAR>,
-<VAR>LFD</VAR>,
-<VAR>NEWLINE</VAR>,
-<VAR>RET</VAR>,
-<VAR>RETURN</VAR>,
-<VAR>RUBOUT</VAR>,
-<VAR>SPACE</VAR>,
-<VAR>SPC</VAR>,
-and
-<VAR>TAB</VAR>.
-
-<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
-denoting an entire key sequence can be specified, by placing
-the key sequence in double quotes.  Some GNU Emacs style key
-escapes can be used, as in the following example, but the
-special character names are not recognized.
-
-
-<PRE>
-"\C-u": universal-argument
-"\C-x\C-r": re-read-init-file
-"\e[11~": "Function Key 1"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is again bound to the function
-<CODE>universal-argument</CODE> (just as it was in the first example),
-<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
-and <SAMP>`<KBD>ESC</KBD> <KBD>[</KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
-the text <SAMP>`Function Key 1'</SAMP>.
-
-</DL>
-
-The following GNU Emacs style escape sequences are available when
-specifying key sequences:
-
-<DL COMPACT>
-
-<DT><CODE><KBD>\C-</KBD></CODE>
-<DD>
-control prefix
-<DT><CODE><KBD>\M-</KBD></CODE>
-<DD>
-meta prefix
-<DT><CODE><KBD>\e</KBD></CODE>
-<DD>
-an escape character
-<DT><CODE><KBD>\\</KBD></CODE>
-<DD>
-backslash
-<DT><CODE><KBD>\"</KBD></CODE>
-<DD>
-<KBD>"</KBD>, a double quotation mark
-<DT><CODE><KBD>\'</KBD></CODE>
-<DD>
-<KBD>'</KBD>, a single quote or apostrophe
-</DL>
-
-In addition to the GNU Emacs style escape sequences, a second
-set of backslash escapes is available:
-
-<DL COMPACT>
-
-<DT><CODE>\a</CODE>
-<DD>
-alert (bell)
-<DT><CODE>\b</CODE>
-<DD>
-backspace
-<DT><CODE>\d</CODE>

-form feed
-<DT><CODE>\n</CODE>
-<DD>
-newline
-<DT><CODE>\r</CODE>
-<DD>
-carriage return
-<DT><CODE>\t</CODE>
-<DD>
-horizontal tab
-<DT><CODE>\v</CODE>
-<DD>
-vertical tab
-<DT><CODE>\<VAR>nnn</VAR></CODE>
-<DD>
-the character whose ASCII code is the octal value <VAR>nnn</VAR>
-(one to three digits)
-<DT><CODE>\x<VAR>nnn</VAR></CODE>
-<DD>
-the character whose ASCII code is the hexadecimal value <VAR>nnn</VAR>
-(one to three digits)
-</DL>
-
-When entering the text of a macro, single or double quotes must
-be used to indicate a macro definition.
-Unquoted text is assumed to be a function name.
-In the macro body, the backslash escapes described above are expanded.
-Backslash will quote any other character in the macro text,
-including <SAMP>`"'</SAMP> and <SAMP>`''</SAMP>.
-For example, the following binding will make <SAMP>`<KBD>C-x</KBD> \'</SAMP>
-insert a single <SAMP>`\'</SAMP> into the line:
-
-<PRE>
-"\C-x\\": "\\"
-</PRE>

-
-<H3><A NAME="SEC11" HREF="readline.html#TOC11">Conditional Init Constructs</A></H3>
-
-<P>
-Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key
-bindings and variable settings to be performed as the result
-of tests.  There are four parser directives used.
-
-</P>
-<DL COMPACT>
-
-<DT><CODE>$if</CODE>
-<DD>
-The <CODE>$if</CODE> construct allows bindings to be made based on the
-editing mode, the terminal being used, or the application using
-Readline.  The text of the test extends to the end of the line;
-no characters are required to isolate it.
-
-<DL COMPACT>
-
-<DT><CODE>mode</CODE>
-<DD>
-The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
-whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
-This may be used in conjunction
-with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
-the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
-Readline is starting out in <CODE>emacs</CODE> mode.
-
-<DT><CODE>term</CODE>
-<DD>
-The <CODE>term=</CODE> form may be used to include terminal-specific
-key bindings, perhaps to bind the key sequences output by the
-terminal's function keys.  The word on the right side of the
-<SAMP>`='</SAMP> is tested against both the full name of the terminal and
-the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
-allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
-for instance.
-
-<DT><CODE>application</CODE>
-<DD>
-The <VAR>application</VAR> construct is used to include
-application-specific settings.  Each program using the Readline
-library sets the <VAR>application name</VAR>, and you can test for
-a particular value. 
-This could be used to bind key sequences to functions useful for
-a specific program.  For instance, the following command adds a
-key sequence that quotes the current or previous word in Bash:
-
-<PRE>
-$if Bash
-# Quote the current or previous word
-"\C-xq": "\eb\"\ef\""
-$endif
-</PRE>
-
-</DL>
-
-<DT><CODE>$endif</CODE>
-<DD>
-This command, as seen in the previous example, terminates an
-<CODE>$if</CODE> command.
-
-<DT><CODE>$else</CODE>
-<DD>
-Commands in this branch of the <CODE>$if</CODE> directive are executed if
-the test fails.
-
-<DT><CODE>$include</CODE>
-<DD>
-This directive takes a single filename as an argument and reads commands
-and bindings from that file.
-For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
-
-<PRE>
-$include /etc/inputrc

-In order to write new functions for Readline, you need to know the
-calling conventions for keyboard-invoked functions, and the names of the
-variables that describe the current state of the line read so far.
-
-</P>
-<P>
-The calling sequence for a command <CODE>foo</CODE> looks like
-
-</P>
-
-<PRE>
-<CODE>foo (int count, int key)</CODE>
-</PRE>
-
-<P>
-where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
-<VAR>key</VAR> is the key that invoked this function.
-
-</P>
-<P>
-It is completely up to the function as to what should be done with the
-numeric argument.  Some functions use it as a repeat count, some
-as a flag, and others to choose alternate behavior (refreshing the current
-line as opposed to refreshing the screen, for example).  Some choose to
-ignore it.  In general, if a
-function uses the numeric argument as a repeat count, it should be able
-to do something useful with both negative and positive arguments.
-At the very least, it should be aware that it can be passed a
-negative argument.

-<H2><A NAME="SEC43" HREF="readline.html#TOC43">Readline Signal Handling</A></H2>
-
-<P>
-Signals are asynchronous events sent to a process by the Unix kernel,
-sometimes on behalf of another process.  They are intended to indicate
-exceptional events, like a user pressing the interrupt key on his terminal,
-or a network connection being broken.  There is a class of signals that can
-be sent to the process currently reading input from the keyboard.  Since
-Readline changes the terminal attributes when it is called, it needs to
-perform special processing when such a signal is received in order to
-restore the terminal to a sane state, or provide application writers with
-functions to do so manually. 
-
-</P>
-<P>
-Readline contains an internal signal handler that is installed for a
-number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
-<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
-When one of these signals is received, the signal handler
-will reset the terminal attributes to those that were in effect before
-<CODE>readline()</CODE> was called, reset the signal handling to what it was
-before <CODE>readline()</CODE> was called, and resend the signal to the calling
-application.
-If and when the calling application's signal handler returns, Readline
-will reinitialize the terminal and continue to accept input.
-When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
-some additional work, which will cause any partially-entered line to be
-aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
-
-</P>
-<P>
-There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
-the kernel sends to a process whenever the terminal's size changes (for
-example, if a user resizes an <CODE>xterm</CODE>).  The Readline <CODE>SIGWINCH</CODE>
-handler updates Readline's internal screen size information, and then calls
-any <CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
-Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
-resetting the terminal to its original state.  If the application's signal
-handler does more than update its idea of the terminal size and return (for
-example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
-call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
-terminal state. 
-
-</P>
-<P>
-Readline provides two variables that allow application writers to
-control whether or not it will catch certain signals and act on them
-when they are received.  It is important that applications change the
-values of these variables only when calling <CODE>readline()</CODE>, not in
-a signal handler, so Readline's internal signal state is not corrupted.

-The internal function <CODE>rl_completion_matches()</CODE> uses an
-application-supplied <EM>generator</EM> function to generate the list of
-possible matches, and then returns the array of these matches.
-The caller should place the address of its generator function in
-<CODE>rl_completion_entry_function</CODE>.
-
-<LI>
-
-The generator function is called repeatedly from
-<CODE>rl_completion_matches()</CODE>, returning a string each time.  The
-arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
-<VAR>text</VAR> is the partial word to be completed.  <VAR>state</VAR> is zero the
-first time the function is called, allowing the generator to perform
-any necessary initialization, and a positive non-zero integer for
-each subsequent call.  The generator function returns
-<CODE>(char *)NULL</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
-no more possibilities left.  Usually the generator function computes the
-list of possible completions when <VAR>state</VAR> is zero, and returns them
-one at a time on subsequent calls.  Each string the generator function
-returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
-frees the strings when it has finished with them.

-<P>
-The following paragraphs describe the notation used to represent
-keystrokes.
-
-</P>
-<P>
-The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
-produced when the <KBD>k</KBD> key is pressed while the Control key
-is depressed.
-
-</P>
-<P>
-The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
-key is pressed.
-The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
-On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
-the space bar), the <KBD>ALT</KBD> on the left side is generally set to
-work as a Meta key.
-The <KBD>ALT</KBD> key on the right may also be configured to work as a
-Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-</P>
-<P>
-If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
-a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
-<EM>first</EM>, and then typing <KBD>k</KBD>.
-Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
-
-</P>
-<P>
-The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
-character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
-
-</P>
-<P>
-In addition, several keys have their own names.  Specifically,
-<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
-stand for themselves when seen in this text, or in an init file
-(see section <A HREF="rluserman.html#SEC9">Readline Init File</A>).
-If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
-produce the desired character.
-The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
-some keyboards.

-Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled.  The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line.  Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections.  Then, when you are satisfied with
-the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
-end of the line to press <KBD>RET</KBD>; the entire line is accepted
-regardless of the location of the cursor within the line.

-In order to enter characters into the line, simply type them.  The typed
-character appears where the cursor was, and then the cursor moves one
-space to the right.  If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
-</P>
-<P>
-Sometimes you may mistype a character, and
-not notice the error until you have typed several other characters.  In
-that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
-correct your mistake.  Afterwards, you can move the cursor to the right
-with <KBD>C-f</KBD>.
-
-</P>
-<P>
-When you add text in the middle of a line, you will notice that characters
-to the right of the cursor are `pushed over' to make room for the text
-that you have inserted.  Likewise, when you delete text behind the cursor,
-characters to the right of the cursor are `pulled back' to fill in the
-blank space created by the removal of the text.  A list of the bare
-essentials for editing the text of an input line follows.

-<P>
-<EM>Killing</EM> text means to delete the text from the line, but to save
-it away for later use, usually by <EM>yanking</EM> (re-inserting)
-it back into the line.
-(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
-

-place later.
-
-</P>
-<P>
-When you use a kill command, the text is saved in a <EM>kill-ring</EM>.
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all.  The kill
-ring is not line specific; the text that you killed on a previously

-another line.
-<A NAME="IDX7"></A>

-Word boundaries are the same as those used by <KBD>M-f</KBD>.
-
-<DT><KBD>M-<KBD>DEL</KBD></KBD>

-Kill from the cursor the start of the previous word, or, if between
-words, to the start of the previous word.
-Word boundaries are the same as those used by <KBD>M-b</KBD>.
-
-<DT><KBD>C-w</KBD>
-<DD>
-Kill from the cursor to the previous whitespace.  This is different than
-<KBD>M-<KBD>DEL</KBD></KBD> because the word boundaries differ.
-
-</DL>
-

-<DT><KBD>C-y</KBD>
-<DD>
-Yank the most recently killed text back into the buffer at the cursor.

-<H3><A NAME="SEC7" HREF="rluserman.html#TOC7">Readline Arguments</A></H3>
-
-<P>
-You can pass numeric arguments to Readline commands.  Sometimes the
-argument acts as a repeat count, other times it is the <I>sign</I> of the
-argument that is significant.  If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction.  For example, to kill text back to the
-start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
-
-</P>
-<P>
-The general way to pass numeric arguments to a command is to type meta
-digits before the command.  If the first `digit' typed is a minus
-sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
-you have typed one meta digit to get the argument started, you can type
-the remainder of the digits, and then the command.  For example, to give
-the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
-which will delete the next ten characters on the input line.
-

-
-
-<H3><A NAME="SEC8" HREF="rluserman.html#TOC8">Searching for Commands in the History</A></H3>
-
-<P>
-Readline provides commands for searching through the command history
-for lines containing a specified string.
-There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
-
-</P>
-<P>
-Incremental searches begin before the user has finished typing the
-search string.
-As each character of the search string is typed, Readline displays
-the next entry from the history matching the string typed so far.
-An incremental search requires only as many characters as needed to
-find the desired history entry.
-To search backward in the history for a particular string, type
-<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
-The characters present in the value of the <CODE>isearch-terminators</CODE> variable
-are used to terminate an incremental search.
-If that variable has not been assigned a value, the <KBD>ESC</KBD> and
-<KBD>C-J</KBD> characters will terminate an incremental search.
-<KBD>C-g</KBD> will abort an incremental search and restore the original line.
-When the search is terminated, the history entry containing the
-search string becomes the current line.
-
-</P>
-<P>
-To find other matching entries in the history list, type <KBD>C-r</KBD> or
-<KBD>C-s</KBD> as appropriate.
-This will search backward or forward in the history for the next
-entry matching the search string typed so far.
-Any other key sequence bound to a Readline command will terminate
-the search and execute that command.
-For instance, a <KBD>RET</KBD> will terminate the search and accept
-the line, thereby executing the command from the history list.
-A movement command will terminate the search, make the last line found
-the current line, and begin editing.
-
-</P>
-<P>
-Non-incremental searches read the entire search string before starting
-to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.

-The syntax is simple:
-
-
-<PRE>

-set editing-mode vi
-</PRE>
-
-Variable names and values, where appropriate, are recognized without regard
-to case. 
-
-A great deal of run-time behavior is changeable with the following
-variables.
-
-<A NAME="IDX9"></A>
-<DL COMPACT>
-
-<DT><CODE>bell-style</CODE>
-<DD>
-<A NAME="IDX10"></A>
-Controls what happens when Readline wants to ring the terminal bell.
-If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
-<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
-If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
-the terminal's bell.
-
-<DT><CODE>comment-begin</CODE>
-<DD>
-<A NAME="IDX11"></A>
-The string to insert at the beginning of the line when the
-<CODE>insert-comment</CODE> command is executed.  The default value
-is <CODE>"#"</CODE>.
-
-<DT><CODE>completion-ignore-case</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
-in a case-insensitive fashion.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>completion-query-items</CODE>
-<DD>
-<A NAME="IDX12"></A>
-The number of possible completions that determines when the user is
-asked whether he wants to see the list of possibilities.  If the
-number of possible completions is greater than this value,
-Readline will ask the user whether or not he wishes to view
-them; otherwise, they are simply listed.
-This variable must be set to an integer value greater than or equal to 0.
-The default limit is <CODE>100</CODE>.
-
-<DT><CODE>convert-meta</CODE>
-<DD>
-<A NAME="IDX13"></A>
-If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
-eighth bit set to an ASCII key sequence by stripping the eighth
-bit and prefixing an <KBD>ESC</KBD> character, converting them to a
-meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
-
-<DT><CODE>disable-completion</CODE>
-<DD>
-<A NAME="IDX14"></A>
-If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
-Completion  characters will be inserted into the line as if they had
-been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>editing-mode</CODE>
-<DD>
-<A NAME="IDX15"></A>
-The <CODE>editing-mode</CODE> variable controls which default set of
-key bindings is used.  By default, Readline starts up in Emacs editing
-mode, where the keystrokes are most similar to Emacs.  This variable can be
-set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
-
-<DT><CODE>enable-keypad</CODE>
-<DD>
-<A NAME="IDX16"></A>
-When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
-keypad when it is called.  Some systems need this to enable the
-arrow keys.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>expand-tilde</CODE>
-<DD>
-<A NAME="IDX17"></A>
-If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
-attempts word completion.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>horizontal-scroll-mode</CODE>
-<DD>
-<A NAME="IDX18"></A>
-This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
-to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
-horizontally on a single screen line when they are longer than the width
-of the screen, instead of wrapping onto a new screen line.  By default,
-this variable is set to <SAMP>`off'</SAMP>.
-
-<DT><CODE>input-meta</CODE>
-<DD>
-<A NAME="IDX19"></A>
-<A NAME="IDX20"></A>
-If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
-will not clear the eighth bit in the characters it reads),
-regardless of what the terminal claims it can support.  The
-default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
-synonym for this variable.
-
-<DT><CODE>isearch-terminators</CODE>
-<DD>
-<A NAME="IDX21"></A>
-The string of characters that should terminate an incremental search without
-subsequently executing the character as a command (see section <A HREF="rluserman.html#SEC8">Searching for Commands in the History</A>).
-If this variable has not been given a value, the characters <KBD>ESC</KBD> and
-<KBD>C-J</KBD> will terminate an incremental search.
-
-<DT><CODE>keymap</CODE>
-<DD>
-<A NAME="IDX22"></A>
-Sets Readline's idea of the current keymap for key binding commands.
-Acceptable <CODE>keymap</CODE> names are
-<CODE>emacs</CODE>,
-<CODE>emacs-standard</CODE>,
-<CODE>emacs-meta</CODE>,
-<CODE>emacs-ctlx</CODE>,
-<CODE>vi</CODE>,
-<CODE>vi-move</CODE>,
-<CODE>vi-command</CODE>, and
-<CODE>vi-insert</CODE>.
-<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
-equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
-The value of the <CODE>editing-mode</CODE> variable also affects the
-default keymap.
-
-<DT><CODE>mark-directories</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, completed directory names have a slash
-appended.  The default is <SAMP>`on'</SAMP>.
-
-<DT><CODE>mark-modified-lines</CODE>
-<DD>
-<A NAME="IDX23"></A>
-This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
-asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
-This variable is <SAMP>`off'</SAMP> by default.
-
-<DT><CODE>output-meta</CODE>
-<DD>
-<A NAME="IDX24"></A>
-If set to <SAMP>`on'</SAMP>, Readline will display characters with the
-eighth bit set directly rather than as a meta-prefixed escape
-sequence.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>print-completions-horizontally</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
-sorted horizontally in alphabetical order, rather than down the screen.
-The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>show-all-if-ambiguous</CODE>
-<DD>
-<A NAME="IDX25"></A>
-This alters the default behavior of the completion functions.  If
-set to <SAMP>`on'</SAMP>, 
-words which have more than one possible completion cause the
-matches to be listed immediately instead of ringing the bell.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>visible-stats</CODE>
-<DD>
-<A NAME="IDX26"></A>
-If set to <SAMP>`on'</SAMP>, a character denoting a file's type
-is appended to the filename when listing possible
-completions.  The default is <SAMP>`off'</SAMP>.
-
-</DL>
-
-<DT>Key Bindings
-<DD>
-The syntax for controlling key bindings in the init file is
-simple.  First you need to find the name of the command that you
-want to change.  The following sections contain tables of the command
-name, the default keybinding, if any, and a short description of what
-the command does.
-
-Once you know the name of the command, simply place on a line
-in the init file the name of the key
-you wish to bind the command to, a colon, and then the name of the
-command.  The name of the key
-can be expressed in different ways, depending on what you find most
-comfortable.
-
-In addition to command names, readline allows keys to be bound
-to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
-
-<DL COMPACT>
-
-<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
-
-<PRE>
-Control-u: universal-argument
-Meta-Rubout: backward-kill-word
-Control-o: "&#62; output"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is bound to the function
-<CODE>universal-argument</CODE>,
-<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
-<KBD>C-o</KBD> is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-<SAMP>`&#62; output'</SAMP> into the line).
-
-A number of symbolic character names are recognized while
-processing this key binding syntax:
-<VAR>DEL</VAR>,
-<VAR>ESC</VAR>,
-<VAR>ESCAPE</VAR>,
-<VAR>LFD</VAR>,
-<VAR>NEWLINE</VAR>,
-<VAR>RET</VAR>,
-<VAR>RETURN</VAR>,

-<VAR>SPC</VAR>,
-and
-<VAR>TAB</VAR>.
-
-<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
-denoting an entire key sequence can be specified, by placing
-the key sequence in double quotes.  Some GNU Emacs style key
-escapes can be used, as in the following example, but the
-special character names are not recognized.
-
-
-<PRE>
-"\C-u": universal-argument
-"\C-x\C-r": re-read-init-file
-"\e[11~": "Function Key 1"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is again bound to the function
-<CODE>universal-argument</CODE> (just as it was in the first example),
-<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
-and <SAMP>`<KBD>ESC</KBD> <KBD>[</KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
-the text <SAMP>`Function Key 1'</SAMP>.
-
-</DL>
-
-The following GNU Emacs style escape sequences are available when
-specifying key sequences:
-

-<DD>
-the character whose ASCII code is the hexadecimal value <VAR>nnn</VAR>
-(one to three digits)
-</DL>
-
-When entering the text of a macro, single or double quotes must
-be used to indicate a macro definition.
-Unquoted text is assumed to be a function name.
-In the macro body, the backslash escapes described above are expanded.
-Backslash will quote any other character in the macro text,
-including <SAMP>`"'</SAMP> and <SAMP>`''</SAMP>.
-For example, the following binding will make <SAMP>`<KBD>C-x</KBD> \'</SAMP>
-insert a single <SAMP>`\'</SAMP> into the line:

-<H3><A NAME="SEC11" HREF="rluserman.html#TOC11">Conditional Init Constructs</A></H3>
-
-<P>
-Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key
-bindings and variable settings to be performed as the result
-of tests.  There are four parser directives used.
-
-</P>
-<DL COMPACT>
-
-<DT><CODE>$if</CODE>
-<DD>
-The <CODE>$if</CODE> construct allows bindings to be made based on the
-editing mode, the terminal being used, or the application using
-Readline.  The text of the test extends to the end of the line;
-no characters are required to isolate it.
-
-<DL COMPACT>
-
-<DT><CODE>mode</CODE>
-<DD>
-The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
-whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
-This may be used in conjunction
-with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
-the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
-Readline is starting out in <CODE>emacs</CODE> mode.
-
-<DT><CODE>term</CODE>
-<DD>
-The <CODE>term=</CODE> form may be used to include terminal-specific
-key bindings, perhaps to bind the key sequences output by the
-terminal's function keys.  The word on the right side of the
-<SAMP>`='</SAMP> is tested against both the full name of the terminal and
-the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
-allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
-for instance.
-
-<DT><CODE>application</CODE>
-<DD>
-The <VAR>application</VAR> construct is used to include
-application-specific settings.  Each program using the Readline
-library sets the <VAR>application name</VAR>, and you can test for
-a particular value. 
-This could be used to bind key sequences to functions useful for
-a specific program.  For instance, the following command adds a
-key sequence that quotes the current or previous word in Bash:
-
-<PRE>
-$if Bash
-# Quote the current or previous word
-"\C-xq": "\eb\"\ef\""
-$endif
-</PRE>
-
-</DL>
-
-<DT><CODE>$endif</CODE>
-<DD>
-This command, as seen in the previous example, terminates an
-<CODE>$if</CODE> command.
-
-<DT><CODE>$else</CODE>
-<DD>
-Commands in this branch of the <CODE>$if</CODE> directive are executed if
-the test fails.
-
-<DT><CODE>$include</CODE>
-<DD>
-This directive takes a single filename as an argument and reads commands
-and bindings from that file.
-For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
-
-<PRE>
-$include /etc/inputrc
-</PRE>
-
-</DL>
-

-# In the interest of general portability, some common bourne shell
-# constructs were avoided because they weren't guaranteed to be available
-# in some earlier implementations.  I've tried to make this program as
-# portable as possible.  Welcome to unix, where the lowest common
-# denominator is rapidly diminishing.
-#
-# Among the more interesting lossages I noticed among Bourne shells:
-#     * No shell functions.
-#     * No `unset' builtin.
-#     * `shift' cannot take a numeric argument, and signals an error if
-#       there are no arguments to shift.

-# Name by which this script was invoked.

-.TH TEXI2HTML 1 "01/05/98"
-.AT 3
-.SH NAME
-texi2html \- a Texinfo to HTML converter
-.SH SYNOPSIS
-.B texi2html [options] file
-.PP
-.B texi2html -check [-verbose] files
-.SH DESCRIPTION
-.I Texi2html
-converts the given Texinfo file to a set of HTML files. It tries to handle
-most of the Texinfo commands. It creates hypertext links for cross-references,
-footnotes...
-.PP
-It also tries to add links from a reference to its corresponding entry in the
-bibliography (if any). It may also handle a glossary (see the
-.B \-glossary
-option).
-.PP
-.I Texi2html
-creates several files depending on the contents of the Texinfo file and on
-the chosen options (see FILES).
-.PP
-The HTML files created by
-.I texi2html
-are closer to TeX than to Info, that's why
-.I texi2html
-converts @iftex sections and not @ifinfo ones by default. You can reverse
-this with the \-expandinfo option.
-.SH OPTIONS
-.TP 12
-.B \-check
-Check the given file and give the list of all things that may be Texinfo commands.
-This may be used to check the output of
-.I texi2html
-to find the Texinfo commands that have been left in the HTML file.
-.TP
-.B \-expandinfo
-Expand @ifinfo sections, not @iftex ones.
-.TP
-.B \-glossary
-Use the section named 'Glossary' to build a list of terms and put links in the HTML
-document from each term toward its definition.
-.TP
-.B \-invisible \fIname\fP
-Use \fIname\fP to create invisible destination anchors for index links
-(you can for instance use the invisible.xbm file shipped with this program).
-This is a workaround for a known bug of many WWW browsers, including netscape.
-.TP
-.B \-I \fIdir\fP
-Look also in \fIdir\fP to find included files.
-.TP
-.B \-menu
-Show the Texinfo menus; by default they are ignored.
-.TP
-.B \-monolithic
-Output only one file, including the table of contents and footnotes.
-.TP
-.B \-number
-Number the sections.
-.TP
-.B \-split_chapter
-Split the output into several HTML files (one per main section:
-chapter, appendix...).
-.TP
-.B \-split_node
-Split the output into several HTML files (one per node).
-.TP
-.B \-usage
-Print usage instructions, listing the current available command-line options.
-.TP
-.B \-verbose
-Give a verbose output. Can be used with the
-.B \-check
-option.
-.PP
-.SH FILES
-By default
-.I texi2html
-creates the following files (foo being the name of the Texinfo file):
-.TP 16
-.B foo_toc.html
-The table of contents.
-.TP
-.B foo.html
-The document's contents.
-.TP
-.B foo_foot.html
-The footnotes (if any).
-.PP
-When used with the
-.B \-split
-option, it creates several files (one per chapter or node), named
-.B foo_n.html
-(n being the indice of the chapter or node), instead of the single
-.B foo.html
-file.
-.PP
-When used with the
-.B \-monolithic
-option, it creates only one file:
-.B foo.html
-.SH VARIABLES
-.I texi2html
-predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
-.SH ADDITIONAL COMMANDS
-.I texi2html
-implements the following non-Texinfo commands (maybe they are in Texinfo now...):
-.TP 16
-.B @ifhtml
-This indicates the start of an HTML section, this section will passed through
-without any modification.
-.TP
-.B @end ifhtml
-This indicates the end of an HTML section.
-.SH VERSION
-This is \fItexi2html\fP version 1.52, 01/05/98.
-.PP
-The latest version of \fItexi2html\fP can be found in WWW, cf. URL
-http://wwwinfo.cern.ch/dis/texi2html/
-.SH AUTHOR
-The main author is Lionel Cons, CERN IT/DIS/OSE, Lionel.Cons@cern.ch.
-Many other people around the net contributed to this program.

-.SH BUGS
-This program does not understand all Texinfo commands (yet).
-.PP
-TeX specific commands (normally enclosed in @iftex) will be
-passed unmodified.

+This document details the changes between this version, readline-4.3,
+and the previous version, readline-4.2a.
+
+1.  Changes to Readline
+
+a.  Fixed output of comment-begin character when listing variable values.
+
+b.  Added some default key bindings for common escape sequences produced by
+    HOME and END keys.
+
+c.  Fixed the mark handling code to be more emacs-compatible.
+
+d.  A bug was fixed in the code that prints possible completions to keep it
+    from printing empty strings in certain circumstances.
+
+e.  Change the key sequence printing code to print ESC as M\- if ESC is a
+    meta-prefix character -- it's easier for users to understand than \e.
+
+f.  Fixed unstifle_history() to return values that match the documentation.
+
+g.  Fixed the event loop (rl_event_hook) to handle the case where the input
+    file descriptor is invalidated.
+
+h.  Fixed the prompt display code to work better when the application has a
+    custom redisplay function.
+
+i.  Changes to make reading and writing the history file a little faster, and
+    to cope with huge history files without calling abort(3) from xmalloc.
+
+j.  The vi-mode `S' and `s' commands are now undone correctly.
+
+k.  Fixed a problem which caused the display to be messed up when the last
+    line of a multi-line prompt (possibly containing invisible characters)
+    was longer than the screen width.
+
+2.  New Features in Readline
+
+a.  Support for key `subsequences':  allows, e.g., ESC and ESC-a to both
+    be bound to readline functions.  Now the arrow keys may be used in vi
+    insert mode.
+
+b.  When listing completions, and the number of lines displayed is more than
+    the screen length, readline uses an internal pager to display the results.
+    This is controlled by the `page-completions' variable (default on).
+
+c.  New code to handle editing and displaying multibyte characters.
+
+d.  The behavior introduced in bash-2.05a of deciding whether or not to
+    append a slash to a completed name that is a symlink to a directory has
+    been made optional, controlled by the `mark-symlinked-directories'
+    variable (default is the 2.05a behavior).
+
+e.  The `insert-comment' command now acts as a toggle if given a numeric
+    argument:  if the first characters on the line don't specify a
+    comment, insert one; if they do, delete the comment text
+
+f.  New application-settable completion variable:
+    rl_completion_mark_symlink_dirs, allows an application's completion
+    function to temporarily override the user's preference for appending
+    slashes to names which are symlinks to directories.
+
+g.  New function available to application completion functions:
+    rl_completion_mode, to tell how the completion function was invoked
+    and decide which argument to supply to rl_complete_internal (to list
+    completions, etc.).
+
+h.  Readline now has an overwrite mode, toggled by the `overwrite-mode'
+    bindable command, which could be bound to `Insert'.
+
+i.  New application-settable completion variable:
+    rl_completion_suppress_append, inhibits appending of
+    rl_completion_append_character to completed words.
+
+j.  New key bindings when reading an incremental search string:  ^W yanks
+    the currently-matched word out of the current line into the search
+    string; ^Y yanks the rest of the current line into the search string,
+    DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2a,
+and the previous version, readline-4.2.
+
+1.  Changes to Readline
+
+a.  More `const' and type casting fixes.
+
+b.  Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+    overflow problems.
+
+c.  The completion code no longer appends a `/' or ` ' to a match when
+    completing a symbolic link that resolves to a directory name, unless
+    the match does not add anything to the word being completed.  This
+    means that a tab will complete the word up to the full name, but not
+    add anything, and a subsequent tab will add a slash.
+
+d.  Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e.  Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f.  Fixed the tty code so that ^V works more than once.
+
+g.  Changed the use of __P((...)) for function prototypes to PARAMS((...))
+    because the use of __P in typedefs conflicted g++ and glibc.
+
+h.  The completion code now attempts to do a better job of preserving the
+    case of the word the user typed if ignoring case in completions.
+
+i.  Readline defaults to not echoing the input and lets the terminal
+    initialization code enable echoing if there is a controlling terminal.
+
+j.  The key binding code now processes only two hex digits after a `\x'
+    escape sequence, and the documentation was changed to note that the
+    octal and hex escape sequences result in an eight-bit value rather
+    than strict ASCII.
+
+k.  Fixed a few places where negative array subscripts could have occurred.
+    
+l.  Fixed the vi-mode code to use a better method to determine the bounds of
+    the array used to hold the marks, and to avoid out-of-bounds references.
+    
+m.  Fixed the defines in chardefs.h to work better when chars are signed.
+    
+n.  Fixed configure.in to use the new names for bash autoconf macros.
+    
+o.  Readline no longer attempts to define its own versions of some ctype
+    macros if they are implemented as functions in libc but not as macros in
+    <ctype.h>.
+
+p.  Fixed a problem where rl_backward could possibly set point to before
+    the beginning of the line.
+
+q.  Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+    include file problems.
+
+2.  New Features in Readline
+
+a.  Added extern declaration for rl_get_termcap to readline.h, making it a
+    public function (it was always there, just not in readline.h).
+
+b.  New #defines in readline.h:  RL_READLINE_VERSION, currently 0x0402,
+    RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c.  New readline variable:  rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d.  New bindable boolean readline variable:  match-hidden-files.  Controls
+    completion of files beginning with a `.' (on Unix).  Enabled by default.
+
+e.  The history expansion code now allows any character to terminate a
+    `:first-' modifier, like csh.
+
+f.  The incremental search code remembers the last search string and uses
+    it if ^R^R is typed without a search string.
+
+h.  New bindable variable `history-preserve-point'.  If set, the history
+    code attempts to place the user at the same location on each history
+    line retrived with previous-history or next-history.

+Basic Installation
+==================
+
+These are installation instructions for Readline-4.3.
+
+The simplest way to compile readline is:
+
+  1. `cd' to the directory containing the readline source code and type
+     `./configure' to configure readline for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes some time.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile readline and build the static readline
+     and history libraries.  If supported, the shared readline and history
+     libraries will be built also.  See below for instructions on compiling
+     the other parts of the distribution.  Typing `make everything' will
+     cause the static and shared libraries (if supported) and the example
+     programs to be built.
+
+  3. Type `make install' to install the static readline and history
+     libraries, the readline include files, the documentation, and, if
+     supported, the shared readline and history libraries.
+
+  4. You can remove the created libraries and object files from the
+     build directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile readline for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the readline developers, and should be used with care.
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It
+uses those values to create a `Makefile' in the build directory,
+and Makefiles in the `doc', `shlib', and `examples'
+subdirectories.  It also creates a `config.h' file containing
+system-dependent definitions.  Finally, it creates a shell script
+`config.status' that you can run in the future to recreate the
+current configuration, a file `config.cache' that saves the
+results of its tests to speed up reconfiguring, and a file
+`config.log' containing compiler output (useful mainly for
+debugging `configure'). 
+
+If you need to do unusual things to compile readline, please try
+to figure out how `configure' could check whether to do them, and
+mail diffs or instructions to <bug-readline@gnu.org> so they can
+be considered for the next release.  If at some point
+`config.cache' contains results you don't want to keep, you may
+remove or edit it. 
+
+The file `configure.in' is used to create `configure' by a
+program called `autoconf'.  You only need `configure.in' if you
+want to change it or regenerate `configure' using a newer version
+of `autoconf'.  The readline `configure.in' requires autoconf
+version 2.50 or newer. 
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile readline for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile readline for one architecture at a
+time in the source code directory.  After you have installed
+readline for one architecture, use `make distclean' before
+reconfiguring for another architecture. 
+
+Installation Names
+==================
+
+By default, `make install' will install the readline libraries in
+`/usr/local/lib', the include files in
+`/usr/local/include/readline', the man pages in `/usr/local/man',
+and the info files in `/usr/local/info'.  You can specify an
+installation prefix other than `/usr/local' by giving `configure'
+the option `--prefix=PATH' or by supplying a value for the
+DESTDIR variable when running `make install'. 
+
+You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. 
+If you give `configure' the option `--exec-prefix=PATH', the
+readline Makefiles will use PATH as the prefix for installing the
+libraries.  Documentation and other data files will still use the
+regular prefix. 
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' can not figure out
+automatically, but need to determine by the type of host readline
+will run on.  Usually `configure' can figure that out, but if it
+prints a message saying it can not guess the host type, give it
+the `--host=TYPE' option.  TYPE can either be a short name for
+the system type, such as `sun4', or a canonical name with three
+fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). 
+
+See the file `config.sub' for the possible values of each field.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: the readline `configure' looks for a site script, but not
+all `configure' scripts do.
+
+Operation Controls
+==================
+
+`configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.
+
+Optional Features
+=================
+
+The readline `configure' recognizes a single `--with-PACKAGE' option:
+
+`--with-curses'
+    This tells readline that it can find the termcap library functions
+    (tgetent, et al.) in the curses library, rather than a separate
+    termcap library.  Readline uses the termcap functions, but does not
+    link with the termcap or curses library itself, allowing applications
+    which link with readline the to choose an appropriate library.
+    This option tells readline to link the example programs with the
+    curses library rather than libtermcap.
+
+`configure' also recognizes two `--enable-FEATURE' options:
+
+`--enable-shared'
+    Build the shared libraries by default on supported platforms.  The
+    default is `yes'.
+
+`--enable-static'
+    Build the static libraries by default.  The default is `yes'.
+ 
+Shared Libraries
+================
+
+There is support for building shared versions of the readline and
+history libraries.  The configure script creates a Makefile in
+the `shlib' subdirectory, and typing `make shared' will cause
+shared versions of the readline and history libraries to be built
+on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.  If
+		shared libraries are not supported, this will be set to
+		`unsupported'.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared' or `make'.  The shared libraries will be created in the
+shlib subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'.

+\`configure' configures readline 4.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+

+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
+              headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+<H2> 1.1 History Expansion </H2>
+<!--docid::SEC2::-->
+<P>
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by <CODE>csh</CODE>.  This section
+describes the syntax used to manipulate the history information.
+</P><P>
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+</P><P>
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+<EM>event</EM>, and the portions of that line that are acted upon are
+called <EM>words</EM>.  Various <EM>modifiers</EM> are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is <SAMP>`!'</SAMP> by default.

+
+Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+</P><P>
+
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history <EM>expansion</EM> function
+is available which provides for a consistent user interface across
+different programs.
+</P><P>
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by <CODE>csh</CODE>.
+</P><P>
+
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+</P><P>
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file <CODE>&#60;readline/history.h&#62;</CODE> in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.

+The following paragraphs describe the notation used to represent
+keystrokes.
+</P><P>
+

+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.

+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</P><P>
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+<EM>first</EM>, and then typing <KBD>k</KBD>.
+Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.

+(see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will

+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+In order to enter characters into the line, simply type them.  The typed

+erase character to back up and delete the mistyped character.
+</P><P>
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In

+<!--docid::SEC7::-->
+<P>
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</P><P>
+
+Readline remembers the last incremental search string.  If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+<P>
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+the terminal's bell.
+<P>
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX6"></A>
+The string to insert at the beginning of the line when the

+is <CODE>"#"</CODE>.
+<P>
+
+<DT><CODE>completion-ignore-case</CODE>

+in a case-insensitive fashion.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX7"></A>
+The number of possible completions that determines when the user is
+asked whether he wants to see the list of possibilities.  If the
+number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.

+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+<P>
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX11"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application

+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX14"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,

+<A NAME="IDX16"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The

+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+<P>
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.  The name of the key
+can be expressed in different ways, depending on what you find most
+comfortable.
+</P><P>
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
+</P><P>
+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "&#62; output"
+</pre></td></tr></table><P>
+
+In the above example, <KBD>C-u</KBD> is bound to the function
+<CODE>universal-argument</CODE>,
+<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
+<KBD>C-o</KBD> is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<SAMP>`&#62; output'</SAMP> into the line).
+</P><P>
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+<VAR>DEL</VAR>,
+<VAR>ESC</VAR>,
+<VAR>ESCAPE</VAR>,
+<VAR>LFD</VAR>,
+<VAR>NEWLINE</VAR>,
+<VAR>RET</VAR>,

+
+<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
+denoting an entire key sequence can be specified, by placing

+</pre></td></tr></table></P><P>
+
+In the above example, <KBD>C-u</KBD> is again bound to the function
+<CODE>universal-argument</CODE> (just as it was in the first example),
+<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
+and <SAMP>`<KBD>ESC</KBD> <KBD>[</KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
+the text <SAMP>`Function Key 1'</SAMP>.

+<!--docid::SEC11::-->
+<P>
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+</P><P>
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+<P>
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+<P>
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+argument, switches to insert mode.  This command affects only
+<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
+Each call to <CODE>readline()</CODE> starts in insert mode.
+<P>
+
+In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
+the text at point rather than pushing the text to the right.

+
+While the Readline library does not have a full set of <CODE>vi</CODE>

+The Readline default is <CODE>emacs</CODE> mode.
+</P><P>
+
+When you enter a line in <CODE>vi</CODE> mode, you are already placed in

+<H2> 2.1 Basic Behavior </H2>
+<!--docid::SEC24::-->
+<P>
+
+Many programs provide a command line interface, such as <CODE>mail</CODE>,
+<CODE>ftp</CODE>, and <CODE>sh</CODE>.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+<CODE>gets()</CODE> or <CODE>fgets()</CODE>.
+</P><P>
+
+<A NAME="IDX174"></A>
+<A NAME="IDX175"></A>
+</P><P>
+
+The function <CODE>readline()</CODE> prints a prompt <VAR>prompt</VAR>
+and then reads and returns a single line of text from the user.
+If <VAR>prompt</VAR> is <CODE>NULL</CODE> or the empty string, no prompt is displayed.
+The line <CODE>readline</CODE> returns is allocated with <CODE>malloc()</CODE>;
+the caller should <CODE>free()</CODE> the line when it has finished with it.
+The declaration for <CODE>readline</CODE> in ANSI C is
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *readline (const char *<VAR>prompt</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+So, one might say
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *line = readline ("Enter a line: ");</CODE>
+</pre></td></tr></table>in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+</P><P>
+
+If <CODE>readline</CODE> encounters an <CODE>EOF</CODE> while reading the line, and the
+line is empty at that point, then <CODE>(char *)NULL</CODE> is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+</P><P>
+
+If you want the user to be able to get at the line later, (with
+<KBD>C-p</KBD> for example), you must call <CODE>add_history()</CODE> to save the
+line away in a <EM>history</EM> list of such lines.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>add_history (line)</CODE>;
+</pre></td></tr></table></P><P>
+
+For full details on the GNU History Library, see the associated manual.
+</P><P>
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard <CODE>gets()</CODE> library
+function, and has the advantage of no static buffer to overflow:
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    {
+      free (line_read);
+      line_read = (char *)NULL;
+    }
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read &#38;&#38; *line_read)
+    add_history (line_read);
+
+  return (line_read);
+}
+</pre></td></tr></table></P><P>
+
+This function gives the user the default behaviour of <KBD>TAB</KBD>
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the <KBD>TAB</KBD> key
+with <CODE>rl_bind_key()</CODE>.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int rl_bind_key (int <VAR>key</VAR>, rl_command_func_t *<VAR>function</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+<CODE>rl_bind_key()</CODE> takes two arguments: <VAR>key</VAR> is the character that
+you want to bind, and <VAR>function</VAR> is the address of the function to
+call when <VAR>key</VAR> is pressed.  Binding <KBD>TAB</KBD> to <CODE>rl_insert()</CODE>
+makes <KBD>TAB</KBD> insert itself.
+<CODE>rl_bind_key()</CODE> returns non-zero if <VAR>key</VAR> is not a valid
+ASCII character code (between 0 and 255).
+</P><P>
+
+Thus, to disable the default <KBD>TAB</KBD> behavior, the following suffices:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>rl_bind_key ('\t', rl_insert);</CODE>
+</pre></td></tr></table></P><P>
+
+This code should be executed once at the start of your program; you
+might write a function called <CODE>initialize_readline()</CODE> which
+performs this and other desired initializations, such as installing
+custom completers (see section <A HREF="readline.html#SEC44">2.6 Custom Completers</A>).

+<!--docid::SEC25::-->
+<P>
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+</P><P>
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file <CODE>&#60;readline/readline.h&#62;</CODE>
+in any file that uses Readline's features.  Since some of the definitions
+in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
+<CODE>&#60;stdio.h&#62;</CODE> should be included before <CODE>readline.h</CODE>.
+</P><P>
+
+<CODE>readline.h</CODE> defines a C preprocessor variable that should
+be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x<VAR>MMmm</VAR>.  <VAR>MM</VAR> is the two-digit major
+version number; <VAR>mm</VAR> is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+<CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

+<H3> 2.2.2 Writing a New Function </H3>
+<!--docid::SEC27::-->
+<P>
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+</P><P>
+
+The calling sequence for a command <CODE>foo</CODE> looks like
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int foo (int count, int key)</CODE>
+</pre></td></tr></table></P><P>
+
+where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
+<VAR>key</VAR> is the key that invoked this function.
+</P><P>
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+</P><P>
+
+A command function should return 0 if its action completes successfully,
+and a non-zero value if some error occurs.

+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Meta-Rubout:	backward-kill-word
+</pre></td></tr></table></P><P>
+
+This binds the keystroke <KBD>Meta-Rubout</KBD> to the function
+<EM>descriptively</EM> named <CODE>backward-kill-word</CODE>.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:
+</P><P>
+
+<A NAME="IDX209"></A>
+<DL>
+<DT><U>Function:</U> int <B>rl_add_defun</B> <I>(const char *name, rl_command_func_t *function, int key)</I>
+<DD>Add <VAR>name</VAR> to the list of named functions.  Make <VAR>function</VAR> be
+the function that gets called.  If <VAR>key</VAR> is not -1, then bind it to
+<VAR>function</VAR> using <CODE>rl_bind_key()</CODE>.
+</DL>
+</P><P>
+
+Using this function alone is sufficient for most applications.  It is
+the recommended way to add a few functions to the default functions that
+Readline has built in.  If you need to do something other
+than adding a function to Readline, you may need to use the
+underlying functions described below.

+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: <CODE>emacs_standard_keymap</CODE>,
+<CODE>emacs_meta_keymap</CODE>, <CODE>emacs_ctlx_keymap</CODE>,
+<CODE>vi_movement_keymap</CODE>, and <CODE>vi_insertion_keymap</CODE>.
+<CODE>emacs_standard_keymap</CODE> is the default, and the examples in
+this manual assume that.
+</P><P>
+
+Since <CODE>readline()</CODE> installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to <CODE>readline()</CODE> will be overridden.
+An alternate mechanism is to install custom key bindings in an
+initialization function assigned to the <CODE>rl_startup_hook</CODE> variable

+<H2> 2.5 Readline Signal Handling </H2>
+<!--docid::SEC43::-->
+<P>
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+</P><P>
+
+Readline contains an internal signal handler that is installed for a
+number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
+<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+<CODE>readline()</CODE> was called, reset the signal handling to what it was
+before <CODE>readline()</CODE> was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
+</P><P>
+
+There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an <CODE>xterm</CODE>).  The Readline <CODE>SIGWINCH</CODE>
+handler updates Readline's internal screen size information, and then calls
+any <CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
+Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
+call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
+terminal state. 
+</P><P>
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling <CODE>readline()</CODE>, not in
+a signal handler, so Readline's internal signal state is not corrupted.

+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+</P><P>
+
+There are three major functions used to perform completion:
+</P><P>
+
+<OL>
+<LI>
+The user-interface function <CODE>rl_complete()</CODE>.  This function is
+called with the same arguments as other bindable Readline functions:
+<VAR>count</VAR> and <VAR>invoking_key</VAR>.
+It isolates the word to be completed and calls
+<CODE>rl_completion_matches()</CODE> to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+<P>
+
+<LI>
+The internal function <CODE>rl_completion_matches()</CODE> uses an
+application-supplied <EM>generator</EM> function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+<CODE>rl_completion_entry_function</CODE>.
+<P>
+
+<LI>
+The generator function is called repeatedly from
+<CODE>rl_completion_matches()</CODE>, returning a string each time.  The
+arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
+<VAR>text</VAR> is the partial word to be completed.  <VAR>state</VAR> is zero the
+first time the function is called, allowing the generator to perform

+It takes three arguments:
+(<CODE>char **</CODE><VAR>matches</VAR>, <CODE>int</CODE> <VAR>num_matches</VAR>, <CODE>int</CODE> <VAR>max_length</VAR>)
+where <VAR>matches</VAR> is the array of matching strings,
+<VAR>num_matches</VAR> is the number of strings in that array, and

+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+<!--docid::SEC7::-->
+<P>
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</P><P>
+
+Readline remembers the last incremental search string.  If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+the terminal's bell.
+<P>
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX6"></A>
+The string to insert at the beginning of the line when the

+<P>
+
+<DT><CODE>completion-ignore-case</CODE>

+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX7"></A>
+The number of possible completions that determines when the user is
+asked whether he wants to see the list of possibilities.  If the
+number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.

+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX14"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width

+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
+equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the

+<P>
+
+<DT><CODE>mark-directories</CODE>

+<DD><A NAME="IDX19"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
+asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
+This variable is <SAMP>`off'</SAMP> by default.

+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX21"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose

+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+<P>
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.  The name of the key
+can be expressed in different ways, depending on what you find most
+comfortable.
+</P><P>
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
+</P><P>
+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "&#62; output"
+</pre></td></tr></table><P>
+
+In the above example, <KBD>C-u</KBD> is bound to the function
+<CODE>universal-argument</CODE>,
+<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
+<KBD>C-o</KBD> is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<SAMP>`&#62; output'</SAMP> into the line).
+</P><P>
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+<VAR>DEL</VAR>,
+<VAR>ESC</VAR>,
+<VAR>ESCAPE</VAR>,
+<VAR>LFD</VAR>,
+<VAR>NEWLINE</VAR>,
+<VAR>RET</VAR>,

+
+<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
+denoting an entire key sequence can be specified, by placing

+
+In the above example, <KBD>C-u</KBD> is again bound to the function
+<CODE>universal-argument</CODE> (just as it was in the first example),
+<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,

+<P>
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+</P><P>
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+<P>
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+<P>
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+argument, switches to insert mode.  This command affects only
+<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
+Each call to <CODE>readline()</CODE> starts in insert mode.
+<P>
+
+In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
+the text at point rather than pushing the text to the right.

+the POSIX 1003.2 standard.

+In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE>
+editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode
+when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode).
+The Readline default is <CODE>emacs</CODE> mode.
+</P><P>
+
+When you enter a line in <CODE>vi</CODE> mode, you are already placed in
+`insertion' mode, as if you had typed an <SAMP>`i'</SAMP>.  Pressing <KBD>ESC</KBD>
+switches you into `command' mode, where you can edit the text of the
+line with the standard <CODE>vi</CODE> movement keys, move to previous
+history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and

+usage="Usage: $program [OPTION]... FILE...
+
+Run each Texinfo or LaTeX FILE through TeX in turn until all
+cross-references are resolved, building all indices.  The directory
+containing each FILE is searched for included files.  The suffix of FILE
+is used to determine its language (LaTeX or Texinfo).
+
+Makeinfo is used to perform Texinfo macro expansion before running TeX
+when needed.
+
+Options:
+  -@                   Use @input instead of \input; for preloaded Texinfo.
+  -b, --batch          No interaction.
+  -c, --clean          Remove all auxiliary files.
+  -D, --debug          Turn on shell debugging (set -x).
+  -e, --expand         Force macro expansion using makeinfo.
+  -I DIR               Search DIR for Texinfo files.
+  -h, --help           Display this help and exit successfully.
+  -l, --language=LANG  Specify the LANG of FILE: LaTeX or Texinfo.
+  -p, --pdf            Use pdftex or pdflatex for processing.
+  -q, --quiet          No output unless errors (implies --batch).
+  -s, --silent         Same as --quiet.
+  -t, --texinfo=CMD    Insert CMD after @setfilename in copy of input file.
+                       Multiple values accumulate.
+  -v, --version        Display version information and exit successfully.
+  -V, --verbose        Report on what is done.
+
+The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
+TEX (or PDFTEX), and TEXINDEX environment variables are used to run
+those commands, if they are set.
+
+Email bug reports to <bug-texinfo@gnu.org>,
+general questions and discussion to <help-texinfo@gnu.org>."

+#     some global string/hash/array variables
+# 2.) For larger changes, reimplement one of the T2H_DEFAULT_<fnc>* routines,
+#     give them another name, and assign them to the respective
+#     $T2H_<fnc> variable.
+
+# As a general interface, the hashes T2H_HREF, T2H_NAME, T2H_NODE hold 
+# href, html-name, node-name of
+# This     -- current section (resp. html page)

+# Contents -- Table of contents
+# Overview -- Short table of contents
+# Index    -- Index page
+# About    -- page which explain "navigation buttons"
+# First    -- first node 
+# Last     -- last node
+#
+# Whether or not the following hash values are set, depends on the context

+	  to libhistory.old right after installing it
+
+				   4/27
+				   ----
+doc/Makefile.in
+	- install {readline,history}.info out of the source directory if

+				    ---
+shlib/Makefile.in
+	- made the suffix rule that creates xx.so from xx.c write the

+	  generated postscript files.  Set to 300 because I don't have
+	  any 600-dpi printers
+	- set LANGUAGE= before calling makeinfo, so messages are in English
+	- add rluserman.{info,dvi,ps,html} to appropriate variables
+	- add rules to create rluserman.{info,dvi,ps,html}

+

+	  constructed from $LIBRARY_VERSION and substituted into Makefiles
+
+				    5/5
+				    ---
+support/shlib-install
+	- OSF/1 installs shared libraries like Solaris
+
+Makefile.in
+	- broke the header file install and uninstall into two new targets:
+	  install-headers and uninstall-headers
+	- install and uninstall depend on install-headers and uninstall-headers
+	  respectively
+	- changed install-shared and uninstall-shared targets to depend on
+	  install-headers and uninstall-headers, respectively, so users may
+	  choose to install only the shared libraries.  I'm not sure about
+	  the uninstall one yet -- maybe it should check whether or not
+	  the static libraries are installed and not remove the header files
+	  if they are
+
+				    9/3
+				    ---
+configure.in, config.h.in
+	- added test for memmove (for later use)
+	- changed version to 4.1-beta1

+
+				    2/4

+
+				 3/17/2000
+				 ---------
+[readline-4.1 released]
+
+				   3/23
+				   ----
+Makefile.in
+	- remove the `-t' argument to ranlib in the install recipe; some
+	  ranlibs don't have it and attempt to create a file named `-t'
+
+				   3/27
+				   ----
+support/shlib-install
+	- install shared libraries unwritable by anyone on HP-UX
+	- changed symlinks to relative pathnames on all platforms
+
+shlib/Makefile.in
+	- added missing `includedir' assignment, substituted by configure
+
+Makefile.in
+	- added missing @SET_MAKE@ so configure can set $MAKE appropriately
+
+configure.in
+	- add call to AC_PROG_MAKE_SET
+
+				   8/30
+				   ----
+shlib/Makefile.in
+	- change the soname bound into the shared libraries, so it includes
+	  only the major version number.  If it includes the minor version,
+	  programs depending on it must be rebuilt (which may or may not be
+	  a bad thing)
+
+				    9/6
+				    ---
+examples/rlfe.c
+	- add -l option to log input and output (-a option appends to logfile)

+
+				   10/18
+				   -----

+
+				   10/30
+				   -----
+configure.in
+	- add -fsigned-char to LOCAL_CFLAGS for Linux running on the IBM
+	  S/390
+
+Makefile.in
+	- added new file, rltypedefs.h, installed by default with `make install'
+
+				   11/2
+				   ----
+compat.c
+	- new file, with backwards-compatibility function definitions
+
+Makefile.in,shlib/Makefile.in
+	- make sure that compat.o/compat.so are built and linked apppropriately
+
+support/shobj-conf
+	- picked up bash version, which means that shared libs built on
+	  linux and BSD/OS 4.x will have an soname that does not include
+	  the minor version number
+
+				   11/13
+				   -----
+examples/rlfe.c
+	- rlfe can perform filename completion for relative pathnames in the
+	  inferior process's context if the OS supports /proc/PID/cwd (linux
+	  does it OK, Solaris is slightly warped, none of the BSDs have it)

+This document details the changes between this version, readline-4.3,
+and the previous version, readline-4.2a.
+
+1.  Changes to Readline
+
+a.  Fixed output of comment-begin character when listing variable values.
+
+b.  Added some default key bindings for common escape sequences produced by
+    HOME and END keys.
+
+c.  Fixed the mark handling code to be more emacs-compatible.
+
+d.  A bug was fixed in the code that prints possible completions to keep it
+    from printing empty strings in certain circumstances.
+
+e.  Change the key sequence printing code to print ESC as M\- if ESC is a
+    meta-prefix character -- it's easier for users to understand than \e.
+
+f.  Fixed unstifle_history() to return values that match the documentation.
+
+g.  Fixed the event loop (rl_event_hook) to handle the case where the input
+    file descriptor is invalidated.
+
+h.  Fixed the prompt display code to work better when the application has a
+    custom redisplay function.
+
+i.  Changes to make reading and writing the history file a little faster, and
+    to cope with huge history files without calling abort(3) from xmalloc.
+
+j.  The vi-mode `S' and `s' commands are now undone correctly.
+
+k.  Fixed a problem which caused the display to be messed up when the last
+    line of a multi-line prompt (possibly containing invisible characters)
+    was longer than the screen width.
+
+2.  New Features in Readline
+
+a.  Support for key `subsequences':  allows, e.g., ESC and ESC-a to both
+    be bound to readline functions.  Now the arrow keys may be used in vi
+    insert mode.
+
+b.  When listing completions, and the number of lines displayed is more than
+    the screen length, readline uses an internal pager to display the results.
+    This is controlled by the `page-completions' variable (default on).
+
+c.  New code to handle editing and displaying multibyte characters.
+
+d.  The behavior introduced in bash-2.05a of deciding whether or not to
+    append a slash to a completed name that is a symlink to a directory has
+    been made optional, controlled by the `mark-symlinked-directories'
+    variable (default is the 2.05a behavior).
+
+e.  The `insert-comment' command now acts as a toggle if given a numeric
+    argument:  if the first characters on the line don't specify a
+    comment, insert one; if they do, delete the comment text
+
+f.  New application-settable completion variable:
+    rl_completion_mark_symlink_dirs, allows an application's completion
+    function to temporarily override the user's preference for appending
+    slashes to names which are symlinks to directories.
+
+g.  New function available to application completion functions:
+    rl_completion_mode, to tell how the completion function was invoked
+    and decide which argument to supply to rl_complete_internal (to list
+    completions, etc.).
+
+h.  Readline now has an overwrite mode, toggled by the `overwrite-mode'
+    bindable command, which could be bound to `Insert'.
+
+i.  New application-settable completion variable:
+    rl_completion_suppress_append, inhibits appending of
+    rl_completion_append_character to completed words.
+
+j.  New key bindings when reading an incremental search string:  ^W yanks
+    the currently-matched word out of the current line into the search
+    string; ^Y yanks the rest of the current line into the search string,
+    DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2a,
+and the previous version, readline-4.2.
+
+1.  Changes to Readline
+
+a.  More `const' and type casting fixes.
+
+b.  Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+    overflow problems.
+
+c.  The completion code no longer appends a `/' or ` ' to a match when
+    completing a symbolic link that resolves to a directory name, unless
+    the match does not add anything to the word being completed.  This
+    means that a tab will complete the word up to the full name, but not
+    add anything, and a subsequent tab will add a slash.
+
+d.  Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e.  Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f.  Fixed the tty code so that ^V works more than once.
+
+g.  Changed the use of __P((...)) for function prototypes to PARAMS((...))
+    because the use of __P in typedefs conflicted g++ and glibc.
+
+h.  The completion code now attempts to do a better job of preserving the
+    case of the word the user typed if ignoring case in completions.
+
+i.  Readline defaults to not echoing the input and lets the terminal
+    initialization code enable echoing if there is a controlling terminal.
+
+j.  The key binding code now processes only two hex digits after a `\x'
+    escape sequence, and the documentation was changed to note that the
+    octal and hex escape sequences result in an eight-bit value rather
+    than strict ASCII.
+
+k.  Fixed a few places where negative array subscripts could have occurred.
+    
+l.  Fixed the vi-mode code to use a better method to determine the bounds of
+    the array used to hold the marks, and to avoid out-of-bounds references.
+    
+m.  Fixed the defines in chardefs.h to work better when chars are signed.
+    
+n.  Fixed configure.in to use the new names for bash autoconf macros.
+    
+o.  Readline no longer attempts to define its own versions of some ctype
+    macros if they are implemented as functions in libc but not as macros in
+    <ctype.h>.
+
+p.  Fixed a problem where rl_backward could possibly set point to before
+    the beginning of the line.
+
+q.  Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+    include file problems.
+
+2.  New Features in Readline
+
+a.  Added extern declaration for rl_get_termcap to readline.h, making it a
+    public function (it was always there, just not in readline.h).
+
+b.  New #defines in readline.h:  RL_READLINE_VERSION, currently 0x0402,
+    RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c.  New readline variable:  rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d.  New bindable boolean readline variable:  match-hidden-files.  Controls
+    completion of files beginning with a `.' (on Unix).  Enabled by default.
+
+e.  The history expansion code now allows any character to terminate a
+    `:first-' modifier, like csh.
+
+f.  The incremental search code remembers the last search string and uses
+    it if ^R^R is typed without a search string.
+
+h.  New bindable variable `history-preserve-point'.  If set, the history
+    code attempts to place the user at the same location on each history
+    line retrived with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2,
+and the previous version, readline-4.1.
+
+1.  Changes to Readline
+
+a.  When setting the terminal attributes on systems using `struct termio',
+    readline waits for output to drain before changing the attributes.
+
+b.  A fix was made to the history word tokenization code to avoid attempts to
+    dereference a null pointer.
+
+c.  Readline now defaults rl_terminal_name to $TERM if the calling application
+    has left it unset, and tries to initialize with the resultant value.
+
+d.  Instead of calling (*rl_getc_function)() directly to get input in certain
+    places, readline now calls rl_read_key() consistently.
+
+e.  Fixed a bug in the completion code that allowed a backslash to quote a
+    single quote inside a single-quoted string.
+
+f.  rl_prompt is no longer assigned directly from the argument to readline(),
+    but uses memory allocated by readline.  This allows constant strings to
+    be passed to readline without problems arising when the prompt processing
+    code wants to modify the string.
+
+g.  Fixed a bug that caused non-interactive history searches to return the
+    wrong line when performing multiple searches backward for the same string.
+
+h.  Many variables, function arguments, and function return values are now
+    declared `const' where appropriate, to improve behavior when linking with
+    C++ code.
+
+i.  The control character detection code now works better on systems where
+    `char' is unsigned by default.
+
+j.  The vi-mode numeric argument is now capped at 999999, just like emacs mode.
+
+k.  The Function, CPFunction, CPPFunction, and VFunction typedefs have been
+    replaced with a set of specific prototyped typedefs, though they are
+    still in the readline header files for backwards compatibility.
+
+m.  Nearly all of the (undocumented) internal global variables in the library
+    now have an _rl_ prefix -- there were a number that did not, like
+    screenheight, screenwidth, alphabetic, etc.
+
+n.  The ding() convenience function has been renamed to rl_ding(), though the
+    old function is still defined for backwards compatibility.
+
+o.  The completion convenience functions filename_completion_function,
+    username_completion_function, and completion_matches now have an rl_
+    prefix, though the old names are still defined for backwards compatibility.
+
+p.  The functions shared by readline and bash (linkage is satisfied from bash
+    when compiling with bash, and internally otherwise) now have an sh_ prefix.
+
+q.  Changed the shared library creation procedure on Linux and BSD/OS 4.x so
+    that the `soname' contains only the major version number rather than the
+    major and minor numbers.
+
+r.  Fixed a redisplay bug that occurred when the prompt spanned more than one
+    physical line and contained invisible characters.
+
+s.  Added a missing `includedir' variable to the Makefile.
+
+t.  When installing the shared libraries, make sure symbolic links are relative.
+
+u.  Added configure test so that it can set `${MAKE}' appropriately.
+
+v.  Fixed a bug in rl_forward that could cause the point to be set to before
+    the beginning of the line in vi mode.
+
+w.  Fixed a bug in the callback read-char interface to make it work when a
+    readline function pushes some input onto the input stream with
+    rl_execute_next (like the incremental search functions).
+
+x.  Fixed a file descriptor leak in the history file manipulation code that
+    was tripped when attempting to truncate a non-regular file (like
+    /dev/null).
+
+y.  Changes to make all of the exported readline functions declared in
+    readline.h have an rl_ prefix (rltty_set_default_bindings is now
+    rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
+
+z.  The formatted documentation included in the base readline distribution
+    is no longer removed on a `make distclean'.
+
+aa. Some changes were made to avoid gcc warnings with -Wall.
+
+bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
+    `set keymap EMACS' works.
+
+cc. The history file writing and truncation functions now return a useful
+    status on error.
+
+dd. Fixed a bug that could cause applications to dereference a NULL pointer
+    if a NULL second argument was passed to history_expand().
+
+ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
+    value, rl_read_key() now immediately returns '\n' (which is assumed to   
+    be bound to accept-line).
+
+2.  New Features in Readline
+
+a.  The blink timeout for paren matching is now settable by applications,
+    via the rl_set_paren_blink_timeout() function.
+
+b.  _rl_executing_macro has been renamed to rl_executing_macro, which means
+    it's now part of the public interface.
+
+c.  Readline has a new variable, rl_readline_state, which is a bitmap that
+    encapsulates the current state of the library; intended for use by
+    callbacks and hook functions.
+
+d.  rlfe has a new -l option to log input and output (-a appends to logfile),
+    a new -n option to set the readline application name, and -v and -h
+    options for version and help information.
+
+e.  rlfe can now perform filename completion for the inferior process if the
+    OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the
+    inferior's current working directory.
+
+f.  A new file, rltypedefs.h, contains the new typedefs for function pointers
+    and is installed by `make install'.
+
+g.  New application-callable function rl_set_prompt(const char *prompt):
+    expands its prompt string argument and sets rl_prompt to the result.
+
+h.  New application-callable function rl_set_screen_size(int rows, int cols):
+    public method for applications to set readline's idea of the screen
+    dimensions.
+
+i.  The history example program (examples/histexamp.c) is now built as one
+    of the examples.
+
+j.  The documentation has been updated to cover nearly all of the public
+    functions and variables declared in readline.h.
+
+k.  New function, rl_get_screen_size (int *rows, int *columns), returns
+    readline's idea of the screen dimensions.
+
+l.  The timeout in rl_gather_tyi (readline keyboard input polling function)
+    is now settable via a function (rl_set_keyboard_input_timeout()).
+
+m.  Renamed the max_input_history variable to history_max_entries; the old
+    variable is maintained for backwards compatibility.
+
+n.  The list of characters that separate words for the history tokenizer is
+    now settable with a variable:  history_word_delimiters.  The default
+    value is as before.
+
+o.  There is a new history.3 manual page documenting the history library.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.1,
+and the previous version, readline-4.0.
+
+1.  Changes to Readline
+
+a.  Changed the HTML documents so that the table-of-contents is no longer
+    a separate file.
+
+b.  Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
+    OSF/1.
+
+c.  The shared library major and minor versions are now constructed
+    automatically by configure and substituted into the makefiles.
+
+d.  It's now possible to install the shared libraries separately from the
+    static libraries.
+
+e.  The history library tries to truncate the history file only if it is a
+    regular file.
+
+f.  A bug that caused _rl_dispatch to address negative array indices on
+    systems with signed chars was fixed.
+
+g.  rl-yank-nth-arg now leaves the history position the same as when it was
+    called.
+
+h.  Changes to the completion code to handle MS-DOS drive-letter:pathname
+    filenames.
+
+i.  Completion is now case-insensitive by default on MS-DOS.
+
+j.  Fixes to the history file manipulation code for MS-DOS.
+
+k.  Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
+
+l.  Some fixes were made to the redisplay code for better operation on MS-DOS.
+
+m.  The quoted-insert code will now insert tty special chars like ^C.
+
+n.  A bug was fixed that caused the display code to reference memory before
+    the start of the prompt string.
+
+o.  More support for __EMX__ (OS/2).
+
+p.  A bug was fixed in readline's signal handling that could cause infinite
+    recursion in signal handlers.
+
+q.  A bug was fixed that caused the point to be less than zero when rl_forward
+    was given a very large numeric argument.
+
+r.  The vi-mode code now gets characters via the application-settable value
+    of rl_getc_function rather than calling rl_getc directly.
+
+s.  The history file code now uses O_BINARY mode when reading and writing
+    the history file on cygwin32.
+
+t.  Fixed a bug in the redisplay code for lines with more than 256 line
+    breaks.
+
+u.  A bug was fixed which caused invisible character markers to not be
+    stripped from the prompt string if the terminal was in no-echo mode.
+    
+v.  Readline no longer tries to get the variables it needs for redisplay 
+    from the termcap entry if the calling application has specified its
+    own redisplay function.  Readline treats the terminal as `dumb' in
+    this case.
+
+w.  Fixes to the SIGWINCH code so that a multiple-line prompt with escape
+    sequences is redrawn correctly.
+
+x.  Changes to the install and install-shared targets so that the libraries
+    and header files are installed separately.
+
+2.  New Features in Readline
+
+a.  A new Readline `user manual' is in doc/rluserman.texinfo.
+
+b.  Parentheses matching is now always compiled into readline, and enabled
+    or disabled when the value of the `blink-matching-paren' variable is
+    changed.
+
+c.  MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+d.  MS-DOS systems now use ~/_history as the default history file.
+
+e.  history-search-{forward,backward} now leave the point at the end of the
+    line when the string to search for is empty, like
+    {reverse,forward}-search-history.
+
+f.  history-search-{forward,backward} now leave the last history line found
+    in the readline buffer if the second or subsequent search fails.
+
+g.  New function for use by applications:  rl_on_new_line_with_prompt, used
+    when an application displays the prompt itself before calling readline().
+
+h.  New variable for use by applications:  rl_already_prompted.  An application
+    that displays the prompt itself before calling readline() must set this to
+    a non-zero value.
+
+i.  A new variable, rl_gnu_readline_p, always 1.  The intent is that an
+    application can verify whether or not it is linked with the `real'
+    readline library or some substitute.
+
+j.  Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
+    is included in the examples subdirectory, though it is not built
+    by default.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.0,
+and the previous version, readline-2.2.
+
+1.  Changes to Readline
+
+a.  The version number is now 4.0, to match the major and minor version
+    numbers on the shared readline and history libraries.  Future
+    releases will maintain the identical numbering.
+
+b.  Fixed a typo in the `make install' recipe that copied libreadline.a
+    to libhistory.old right after installing it.
+
+c.  The readline and history info files are now installed out of the source
+    directory if they are not found in the build directory.
+
+d.  The library no longer exports a function named `savestring' -- backwards
+    compatibility be damned.
+
+e.  There is no longer any #ifdef SHELL code in the source files.
+
+f.  Some changes were made to the key binding code to fix memory leaks and
+    better support Win32 systems.
+
+g.  Fixed a silly typo in the paren matching code -- it's microseconds, not
+    milliseconds.
+
+h.  The readline library should be compilable by C++ compilers.
+
+i.  The readline.h public header file now includes function prototypes for
+    all readline functions, and some changes were made to fix errors in the
+    source files uncovered by the use of prototypes.
+
+j.  The maximum numeric argument is now clamped at 1000000.
+
+k.  Fixes to rl_yank_last_arg to make it behave better.
+
+l.  Fixed a bug in the display code that caused core dumps if the prompt
+    string length exceeded 1024 characters.
+
+m.  The menu completion code was fixed to properly insert a single completion
+    if there is only one match.
+
+n.  A bug was fixed that caused the display code to improperly display tabs
+    after newlines.
+
+o.  A fix was made to the completion code in which a typo caused the wrong
+    value to be passed to the function that computed the longest common
+    prefix of the list of matches.
+
+p.  The completion code now checks the value of rl_filename_completion_desired,
+    which is set by application-supplied completion functions to indicate
+    that filename completion is being performed, to decide whether or not to
+    call an application-supplied `ignore completions' function.
+
+q.  Code was added to the history library to catch history substitutions
+    using `&' without a previous history substitution or search having been
+    performed.
+
+
+2.  New Features in Readline
+
+a.  There is a new script, support/shobj-conf, to do system-specific shared
+    object and library configuration.  It generates variables for configure
+    to substitute into makefiles.  The README file provides a detailed
+    explanation of the shared library creation process.
+
+b.  Shared libraries and objects are now built in the `shlib' subdirectory.
+    There is a shlib/Makefile.in to control the build process.  `make shared'
+    from the top-level directory is still the right way to build shared
+    versions of the libraries.
+
+c.  rlconf.h is now installed, so applications can find out which features
+    have been compiled into the installed readline and history libraries.
+
+d.  rlstdc.h is now an installed header file.
+
+e.  Many changes to the signal handling:
+        o Readline now catches SIGQUIT and cleans up the tty before returning;
+        o A new variable, rl_catch_signals, is available to application writers 
+          to indicate to readline whether or not it should install its own
+          signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+          SIGTTIN, and SIGTTOU;
+        o A new variable, rl_catch_sigwinch, is available to application
+          writers to indicate to readline whether or not it should install its
+          own signal handler for SIGWINCH, which will chain to the calling
+          applications's SIGWINCH handler, if one is installed;
+        o There is a new function, rl_free_line_state, for application signal
+          handlers to call to free up the state associated with the current
+          line after receiving a signal;
+        o There is a new function, rl_cleanup_after_signal, to clean up the
+          display and terminal state after receiving a signal;
+        o There is a new function, rl_reset_after_signal, to reinitialize the
+          terminal and display state after an application signal handler
+          returns and readline continues
+
+f.  There is a new function, rl_resize_terminal, to reset readline's idea of
+    the screen size after a SIGWINCH.
+
+g.  New public functions: rl_save_prompt and rl_restore_prompt.  These were
+    previously private functions with a `_' prefix.  These functions are
+    used when an application wants to write a message to the `message area'
+    with rl_message and have the prompt restored correctly when the message
+    is erased.
+
+h.  New function hook: rl_pre_input_hook, called just before readline starts
+    reading input, after initialization.
+
+i.  New function hook: rl_display_matches_hook, called when readline would
+    display the list of completion matches.  The new function
+    rl_display_match_list is what readline uses internally, and is available
+    for use by application functions called via this hook.
+
+j.  New bindable function, delete-char-or-list, like tcsh.
+
+k.  A new variable, rl_erase_empty_line, which, if set by an application using
+    readline, will cause readline to erase, prompt and all, lines on which the
+    only thing typed was a newline.
+
+l.  There is a new script, support/shlib-install, to install and uninstall
+    the shared readline and history libraries.
+
+m.  A new bindable variable, `isearch-terminators', which is a string
+    containing the set of characters that should terminate an incremental
+    search without being executed as a command.
+
+n.  A new bindable function, forward-backward-delete-char.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-2.2,
+and the previous version, readline-2.1.
+
+1.  Changes to Readline
+
+a.  Added a missing `extern' to a declaration in readline.h that kept
+    readline from compiling cleanly on some systems.
+
+b.  The history file is now opened with mode 0600 when it is written for
+    better security.
+
+c.  Changes were made to the SIGWINCH handling code so that prompt redisplay
+    is done better.
+
+d.  ^G now interrupts incremental searches correctly.
+
+e.  A bug that caused a core dump when the set of characters to be quoted
+    when completing words was empty was fixed.
+
+f.  Fixed a problem in the readline test program rltest.c that caused a core
+    dump.
+
+g.  The code that handles parser directives in inputrc files now displays
+    more error messages.
+
+h.  The history expansion code was fixed so that the appearance of the
+    history comment character at the beginning of a word inhibits history
+    expansion for that word and the rest of the input line.
+
+i.  The code that prints completion listings now behaves better if one or
+    more of the filenames contains non-printable characters.
+
+j.  The time delay when showing matching parentheses is now 0.5 seconds.
+
+
+2.  New Features in Readline
+
+a.  There is now an option for `iterative' yank-last-arg handline, so a user
+    can keep entering `M-.', yanking the last argument of successive history
+    lines.
+
+b.  New variable, `print-completions-horizontally', which causes completion
+    matches to be displayed across the screen (like `ls -x') rather than up
+    and down the screen (like `ls').
+
+c.  New variable, `completion-ignore-case', which causes filename completion
+    and matching to be performed case-insensitively.
+
+d.  There is a new bindable command, `magic-space', which causes history
+    expansion to be performed on the current readline buffer and a space to
+    be inserted into the result.
+
+e.  There is a new bindable command, `menu-complete', which enables tcsh-like
+    menu completion (successive executions of menu-complete insert a single
+    completion match, cycling through the list of possible completions).
+
+f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
+    systems, to insert the text from the Win32 clipboard into the editing
+    buffer.
+
+g.  The key sequence translation code now understands printf-style backslash
+    escape sequences, including \NNN octal escapes.  These escape sequences
+    may be used in key sequence definitions or macro values.
+
+h.  An `$include' inputrc file parser directive has been added.

+Basic Installation
+==================
+
+These are installation instructions for Readline-4.3.
+
+The simplest way to compile readline is:
+
+  1. `cd' to the directory containing the readline source code and type
+     `./configure' to configure readline for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes some time.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile readline and build the static readline
+     and history libraries.  If supported, the shared readline and history
+     libraries will be built also.  See below for instructions on compiling
+     the other parts of the distribution.  Typing `make everything' will
+     cause the static and shared libraries (if supported) and the example
+     programs to be built.
+
+  3. Type `make install' to install the static readline and history
+     libraries, the readline include files, the documentation, and, if
+     supported, the shared readline and history libraries.
+
+  4. You can remove the created libraries and object files from the
+     build directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile readline for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the readline developers, and should be used with care.
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It
+uses those values to create a `Makefile' in the build directory,
+and Makefiles in the `doc', `shlib', and `examples'
+subdirectories.  It also creates a `config.h' file containing
+system-dependent definitions.  Finally, it creates a shell script
+`config.status' that you can run in the future to recreate the
+current configuration, a file `config.cache' that saves the
+results of its tests to speed up reconfiguring, and a file
+`config.log' containing compiler output (useful mainly for
+debugging `configure'). 
+
+If you need to do unusual things to compile readline, please try
+to figure out how `configure' could check whether to do them, and
+mail diffs or instructions to <bug-readline@gnu.org> so they can
+be considered for the next release.  If at some point
+`config.cache' contains results you don't want to keep, you may
+remove or edit it. 
+
+The file `configure.in' is used to create `configure' by a
+program called `autoconf'.  You only need `configure.in' if you
+want to change it or regenerate `configure' using a newer version
+of `autoconf'.  The readline `configure.in' requires autoconf
+version 2.50 or newer. 
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile readline for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile readline for one architecture at a
+time in the source code directory.  After you have installed
+readline for one architecture, use `make distclean' before
+reconfiguring for another architecture. 
+
+Installation Names
+==================
+
+By default, `make install' will install the readline libraries in
+`/usr/local/lib', the include files in
+`/usr/local/include/readline', the man pages in `/usr/local/man',
+and the info files in `/usr/local/info'.  You can specify an
+installation prefix other than `/usr/local' by giving `configure'
+the option `--prefix=PATH' or by supplying a value for the
+DESTDIR variable when running `make install'. 
+
+You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. 
+If you give `configure' the option `--exec-prefix=PATH', the
+readline Makefiles will use PATH as the prefix for installing the
+libraries.  Documentation and other data files will still use the
+regular prefix. 
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' can not figure out
+automatically, but need to determine by the type of host readline
+will run on.  Usually `configure' can figure that out, but if it
+prints a message saying it can not guess the host type, give it
+the `--host=TYPE' option.  TYPE can either be a short name for
+the system type, such as `sun4', or a canonical name with three
+fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). 
+
+See the file `config.sub' for the possible values of each field.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: the readline `configure' looks for a site script, but not
+all `configure' scripts do.
+
+Operation Controls
+==================
+
+`configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.
+
+Optional Features
+=================
+
+The readline `configure' recognizes a single `--with-PACKAGE' option:
+
+`--with-curses'
+    This tells readline that it can find the termcap library functions
+    (tgetent, et al.) in the curses library, rather than a separate
+    termcap library.  Readline uses the termcap functions, but does not
+    link with the termcap or curses library itself, allowing applications
+    which link with readline the to choose an appropriate library.
+    This option tells readline to link the example programs with the
+    curses library rather than libtermcap.
+
+`configure' also recognizes two `--enable-FEATURE' options:
+
+`--enable-shared'
+    Build the shared libraries by default on supported platforms.  The
+    default is `yes'.
+
+`--enable-static'
+    Build the static libraries by default.  The default is `yes'.
+ 
+Shared Libraries
+================
+
+There is support for building shared versions of the readline and
+history libraries.  The configure script creates a Makefile in
+the `shlib' subdirectory, and typing `make shared' will cause
+shared versions of the readline and history libraries to be built
+on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.  If
+		shared libraries are not supported, this will be set to
+		`unsupported'.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared' or `make'.  The shared libraries will be created in the
+shlib subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'.

+Introduction
+============
+
+This is the Gnu Readline library, version 4.3.
+
+The Readline library provides a set of functions for use by applications
+that allow users to edit command lines as they are typed in.  Both
+Emacs and vi editing modes are available.  The Readline library includes
+additional functions to maintain a list of previously-entered command
+lines, to recall and perhaps reedit those lines, and perform csh-like
+history expansion on previous commands.
+
+The history facilites are also placed into a separate library, the
+History library, as part of the build process.  The History library
+may be used without Readline in applications which desire its
+capabilities.
+
+The Readline library is free software, distributed under the terms of
+the [GNU] General Public License, version 2.  For more information, see
+the file COPYING.
+
+To build the library, try typing `./configure', then `make'.  The
+configuration process is automated, so no further intervention should
+be necessary.  Readline builds with `gcc' by default if it is
+available.  If you want to use `cc' instead, type
+
+        CC=cc ./configure
+
+if you are using a Bourne-style shell.  If you are not, the following
+may work:
+
+        env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.
+
+The file rlconf.h contains C preprocessor defines that enable and disable
+certain Readline features.
+
+The special make target `everything' will build the static and shared
+libraries (if the target platform supports them) and the examples.
+
+Examples
+========
+
+There are several example programs that use Readline features in the
+examples directory.  The `rl' program is of particular interest.  It
+is a command-line interface to Readline, suitable for use in shell
+scripts in place of `read'.
+
+Shared Libraries
+================
+
+There is skeletal support for building shared versions of the
+Readline and History libraries.  The configure script creates
+a Makefile in the `shlib' subdirectory, and typing `make shared'
+will cause shared versions of the Readline and History libraries
+to be built on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared'.  The shared libraries will be created in the shlib
+subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'. 
+
+Documentation
+=============
+
+The documentation for the Readline and History libraries appears in
+the `doc' subdirectory.  There are three texinfo files and a
+Unix-style manual page describing the facilities available in the
+Readline library.  The texinfo files include both user and
+programmer's manuals.  HTML versions of the manuals appear in the
+`doc' subdirectory as well. 
+
+Reporting Bugs
+==============
+
+Bug reports for Readline should be sent to:
+
+        bug-readline@gnu.org
+
+When reporting a bug, please include the following information:
+
+        * the version number and release status of Readline (e.g., 4.2-release)
+        * the machine and OS that it is running on
+        * a list of the compilation flags or the contents of `config.h', if
+          appropriate
+        * a description of the bug
+        * a recipe for recreating the bug reliably
+        * a fix for the bug if you have one!
+
+If you would like to contact the Readline maintainer directly, send mail
+to bash-maintainers@gnu.org.
+
+Since Readline is developed along with bash, the bug-bash@gnu.org mailing
+list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
+Readline bug reports and fixes.

+Subject: Use of Readline
+Reply-to: rms@gnu.org
+
+I think Allbery's suggestion is a good one.  So please add this text
+in a suitable place.  Please don't put it in the GPL itself; that
+should be the same as the GPL everywhere else.  Putting it in the
+README and/or the documentation would be a good idea.
+
+
+======================================================================
+Our position on the use of Readline through a shared-library linking
+mechanism is that there is no legal difference between shared-library
+linking and static linking--either kind of linking combines various
+modules into a single larger work.  The conditions for using Readline
+in a larger work are stated in section 3 of the GNU GPL.

+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+.if n The GNU History Library is Copyright (C) 1989-2002 by the Free Software Foundation, Inc.
+.SH DESCRIPTION
+Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+.PP
+.SH "HISTORY EXPANSION"
+.PP
+The history library supports a history expansion feature that
+is identical to the history expansion in
+.BR bash.
+This section describes what syntax features are available.
+.PP
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+.PP
+History expansion is usually performed immediately after a complete line
+is read.
+It takes place in two parts.
+The first is to determine which line from the history list
+to use during substitution.
+The second is to select portions of that line for inclusion into
+the current one.
+The line selected from the history is the \fIevent\fP,
+and the portions of that line that are acted upon are \fIwords\fP.
+Various \fImodifiers\fP are available to manipulate the selected words.
+The line is broken into words in the same fashion as \fBbash\fP
+does when reading input,
+so that several words that would otherwise be separated 
+are considered one word when surrounded by quotes (see the
+description of \fBhistory_tokenize()\fP below).
+History expansions are introduced by the appearance of the
+history expansion character, which is \^\fB!\fP\^ by default.
+Only backslash (\^\fB\e\fP\^) and single quotes can quote
+the history expansion character.
+.SS Event Designators
+.PP
+An event designator is a reference to a command line entry in the
+history list.
+.PP
+.PD 0
+.TP
+.B !
+Start a history substitution, except when followed by a
+.BR blank ,
+newline, = or (.
+.TP
+.B !\fIn\fR
+Refer to command line
+.IR n .
+.TP
+.B !\-\fIn\fR
+Refer to the current command line minus
+.IR n .
+.TP
+.B !!
+Refer to the previous command.  This is a synonym for `!\-1'.
+.TP
+.B !\fIstring\fR
+Refer to the most recent command starting with 
+.IR string .
+.TP
+.B !?\fIstring\fR\fB[?]\fR
+Refer to the most recent command containing
+.IR string .
+The trailing \fB?\fP may be omitted if
+.I string
+is followed immediately by a newline.
+.TP
+.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u
+Quick substitution.  Repeat the last command, replacing
+.I string1
+with
+.IR string2 .
+Equivalent to
+``!!:s/\fIstring1\fP/\fIstring2\fP/''
+(see \fBModifiers\fP below).
+.TP
+.B !#
+The entire command line typed so far.
+.PD
+.SS Word Designators
+.PP
+Word designators are used to select desired words from the event.
+A 
+.B :
+separates the event specification from the word designator.
+It may be omitted if the word designator begins with a
+.BR ^ ,
+.BR $ ,
+.BR * ,
+.BR \- ,
+or
+.BR % .
+Words are numbered from the beginning of the line,
+with the first word being denoted by 0 (zero).
+Words are inserted into the current line separated by single spaces.
+.PP
+.PD 0
+.TP
+.B 0 (zero)
+The zeroth word.  For the shell, this is the command
+word.
+.TP
+.I n
+The \fIn\fRth word.
+.TP
+.B ^
+The first argument.  That is, word 1.
+.TP
+.B $
+The last argument.
+.TP
+.B %
+The word matched by the most recent `?\fIstring\fR?' search.
+.TP
+.I x\fB\-\fPy
+A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'.
+.TP
+.B *
+All of the words but the zeroth.  This is a synonym
+for `\fI1\-$\fP'.  It is not an error to use
+.B *
+if there is just one
+word in the event; the empty string is returned in that case.
+.TP
+.B x*
+Abbreviates \fIx\-$\fP.
+.TP
+.B x\-
+Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word.
+.PD
+.PP
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+.SS Modifiers
+.PP
+After the optional word designator, there may appear a sequence of
+one or more of the following modifiers, each preceded by a `:'.
+.PP
+.PD 0
+.PP
+.TP
+.B h
+Remove a trailing file name component, leaving only the head.
+.TP
+.B t
+Remove all leading file name components, leaving the tail.
+.TP
+.B r
+Remove a trailing suffix of the form \fI.xxx\fP, leaving the
+basename.
+.TP
+.B e
+Remove all but the trailing suffix.
+.TP
+.B p
+Print the new command but do not execute it.
+.TP
+.B q
+Quote the substituted words, escaping further substitutions.
+.TP
+.B x
+Quote the substituted words as with
+.BR q ,
+but break into words at
+.B blanks
+and newlines.
+.TP
+.B s/\fIold\fP/\fInew\fP/
+Substitute
+.I new
+for the first occurrence of
+.I old
+in the event line.  Any delimiter can be used in place of /.  The
+final delimiter is optional if it is the last character of the
+event line.  The delimiter may be quoted in
+.I old
+and
+.I new
+with a single backslash.  If & appears in
+.IR new ,
+it is replaced by
+.IR old .
+A single backslash will quote the &.  If
+.I old
+is null, it is set to the last
+.I old
+substituted, or, if no previous history substitutions took place,
+the last
+.I string
+in a
+.B !?\fIstring\fR\fB[?]\fR
+search.
+.TP
+.B &
+Repeat the previous substitution.
+.TP
+.B g
+Cause changes to be applied over the entire event line.  This is
+used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR')
+or `\fB:&\fP'.  If used with
+`\fB:s\fP', any delimiter can be used
+in place of /, and the final delimiter is optional
+if it is the last character of the event line.
+.PD
+.SH "PROGRAMMING WITH HISTORY FUNCTIONS"
+This section describes how to use the History library in other programs.
+.SS Introduction to History
+.PP
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history \fIexpansion\fP function
+is available which provides for a consistent user interface across
+different programs.
+.PP
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are
+identical to
+the history substitution provided by \fBbash\fP.
+.PP
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+.PP
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file
+.FN <readline/history.h>
+in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+
+.SS History Storage
+.PP
+The history list is an array of history entries.  A history entry is
+declared as follows:
+.PP
+.Vb "typedef void *" histdata_t;
+.PP
+.nf
+typedef struct _hist_entry {
+  char *line;
+  histdata_t data;
+} HIST_ENTRY;
+.fi
+.PP
+The history list itself might therefore be declared as
+.PP
+.Vb "HIST_ENTRY **" the_history_list;
+.PP
+The state of the History library is encapsulated into a single structure:
+.PP
+.nf
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state {
+  HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+  int offset;           /* The location pointer within this array. */
+  int length;           /* Number of elements within this array. */
+  int size;             /* Number of slots allocated to this array. */
+  int flags;
+} HISTORY_STATE;
+.fi
+.PP
+If the flags member includes \fBHS_STIFLED\fP, the history has been
+stifled.
+.SH "History Functions"
+.PP
+This section describes the calling sequence for the various functions
+exported by the GNU History library.
+.SS Initializing History and State Management
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+.Fn1 void using_history void
+Begin a session in which the history functions might be used.  This
+initializes the interactive variables.
+
+.Fn1 "HISTORY_STATE *" history_get_history_state void
+Return a structure describing the current state of the input history.
+
+.Fn1 void history_set_history_state "HISTORY_STATE *state"
+Set the state of the history list according to \fIstate\fP.
+
+.SS History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+.Fn1 void add_history "const char *string"
+Place \fIstring\fP at the end of the history list.  The associated data
+field (if any) is set to \fBNULL\fP.
+
+.Fn1 "HIST_ENTRY *" remove_history "int which"
+Remove history entry at offset \fIwhich\fP from the history.  The
+removed element is returned so you can free the line, data,
+and containing structure.
+
+.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data"
+Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP.
+This returns the old entry so you can dispose of the data.  In the case
+of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned.
+
+.Fn1 void clear_history "void"
+Clear the history list by deleting all the entries.
+
+.Fn1 void stifle_history "int max"
+Stifle the history list, remembering only the last \fImax\fP entries.
+
+.Fn1 int unstifle_history "void"
+Stop stifling the history.  This returns the previously-set
+maximum number of history entries (as set by \fBstifle_history()\fP).
+history was stifled.  The value is positive if the history was
+stifled, negative if it wasn't.
+
+.Fn1 int history_is_stifled "void"
+Returns non-zero if the history is stifled, zero if it is not.
+
+.SS Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+.Fn1 "HIST_ENTRY **" history_list "void"
+Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the
+current input history.  Element 0 of this list is the beginning of time.
+If there is no history, return \fBNULL\fP.
+
+.Fn1 int where_history "void"
+Returns the offset of the current history element.

+\fI*cindex\fP.  \fI*cindex\fP is modified to point to after the event
+specifier.  At function entry, \fIcindex\fP points to the index into
+\fIstring\fP where the history event specification begins.  \fIqchar\fP
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.

+
+This section describes the externally-visible variables exported by
+the GNU History Library.
+
+.Vb int history_base
+The logical offset of the first entry in the history list.
+
+.Vb int history_length
+The number of entries currently stored in the history list.
+
+.Vb int history_max_entries
+The maximum number of history entries.  This must be changed using
+\fBstifle_history()\fP.
+
+.Vb char history_expansion_char
+The character that introduces a history event.  The default is \fB!\fP.
+Setting this to 0 inhibits history expansion.
+
+.Vb char history_subst_char
+The character that invokes word substitution if found at the start of
+a line.  The default is \fB^\fP.
+
+.Vb char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+
+.Vb "char *" history_word_delimiters
+The characters that separate tokens for \fBhistory_tokenize()\fP.
+The default value is \fB"\ \et\en()<>;&|"\fP.
+
+.Vb "char *" history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following \fBhistory_expansion_char\fP.  The default is space, tab, newline,
+\fB\er\fP, and \fB=\fP.
+
+.Vb "char *" history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to space, tab, \fI:\fP and \fI?\fP in the case of
+a substring search.  The default is empty.
+
+.Vb int history_quotes_inhibit_expansion
+If non-zero, single-quoted words are not scanned for the history expansion
+character.  The default value is 0.
+
+.Vb "rl_linebuf_func_t *" history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a \fBchar *\fP (\fIstring\fP)
+and an \fBint\fP index into that string (\fIi\fP).
+It should return a non-zero value if the history expansion starting at
+\fIstring[i]\fP should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like \fBbash\fP that use the history
+expansion character for additional purposes.
+By default, this variable is set to \fBNULL\fP.

+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the @sc{gnu} Readline Library and
+other programs.  If you are a programmer, and you wish to include the
+features found in @sc{gnu} Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.
+

+* Basic Behavior::	Using the default behavior of Readline.
+* Custom Functions::	Adding your own functions to Readline.
+* Readline Variables::			Variables accessible to custom
+					functions.
+* Readline Convenience Functions::	Functions which Readline supplies to
+					aid in writing your own custom

+* Custom Completers::	Supplanting or supplementing Readline's
+			completion functions.
+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+@code{gets()} or @code{fgets()}.
+
+@findex readline
+@cindex readline, function
+
+The function @code{readline()} prints a prompt @var{prompt}
+and then reads and returns a single line of text from the user.
+If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed.
+The line @code{readline} returns is allocated with @code{malloc()};
+the caller should @code{free()} the line when it has finished with it.
+The declaration for @code{readline} in ANSI C is
+
+@example
+@code{char *readline (const char *@var{prompt});}
+@end example
+
+@noindent
+So, one might say
+@example
+@code{char *line = readline ("Enter a line: ");}
+@end example
+@noindent
+in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+If @code{readline} encounters an @code{EOF} while reading the line, and the
+line is empty at that point, then @code{(char *)NULL} is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+If you want the user to be able to get at the line later, (with
+@key{C-p} for example), you must call @code{add_history()} to save the
+line away in a @dfn{history} list of such lines.
+
+@example
+@code{add_history (line)};
+@end example
+
+@noindent
+For full details on the GNU History Library, see the associated manual.
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard @code{gets()} library
+function, and has the advantage of no static buffer to overflow:
+
+@example
+/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+@{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    @{
+      free (line_read);
+      line_read = (char *)NULL;
+    @}
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read && *line_read)
+    add_history (line_read);
+
+  return (line_read);
+@}
+@end example
+
+This function gives the user the default behaviour of @key{TAB}
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the @key{TAB} key
+with @code{rl_bind_key()}.
+
+@example
+@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});}
+@end example
+
+@code{rl_bind_key()} takes two arguments: @var{key} is the character that
+you want to bind, and @var{function} is the address of the function to
+call when @var{key} is pressed.  Binding @key{TAB} to @code{rl_insert()}
+makes @key{TAB} insert itself.
+@code{rl_bind_key()} returns non-zero if @var{key} is not a valid
+ASCII character code (between 0 and 255).
+
+Thus, to disable the default @key{TAB} behavior, the following suffices:
+@example
+@code{rl_bind_key ('\t', rl_insert);}
+@end example
+
+This code should be executed once at the start of your program; you
+might write a function called @code{initialize_readline()} which
+performs this and other desired initializations, such as installing
+custom completers (@pxref{Custom Completers}).
+
+@node Custom Functions
+@section Custom Functions
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file @code{<readline/readline.h>}
+in any file that uses Readline's features.  Since some of the definitions
+in @code{readline.h} use the @code{stdio} library, the file
+@code{<stdio.h>} should be included before @code{readline.h}.
+
+@code{readline.h} defines a C preprocessor variable that should
+be treated as an integer, @code{RL_READLINE_VERSION}, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x@var{MMmm}.  @var{MM} is the two-digit major
+version number; @var{mm} is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+@code{RL_READLINE_VERSION} would be @code{0x0402}. 
+
+@menu
+* Readline Typedefs::	C declarations to make code readable.
+* Function Writing::	Variables and calling conventions.
+@end menu
+
+@node Readline Typedefs
+@subsection Readline Typedefs
+
+For readabilty, we declare a number of new object types, all pointers
+to functions.
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+For instance, say we want to declare a variable @var{func} as a pointer
+to a function which takes two @code{int} arguments and returns an
+@code{int} (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+@code{int (*func)();}
+
+@noindent
+or the ANSI-C style declaration
+
+@code{int (*func)(int, int);}
+
+@noindent
+we may write
+
+@code{rl_command_func_t *func;}
+
+The full list of function pointer types available is
+
+@table @code
+@item typedef int rl_command_func_t (int, int);
+
+@item typedef char *rl_compentry_func_t (const char *, int);
+
+@item typedef char **rl_completion_func_t (const char *, int, int);
+
+@item typedef char *rl_quote_func_t (char *, int, char *);

+@node Function Writing
+@subsection Writing a New Function
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+The calling sequence for a command @code{foo} looks like
+
+@example
+@code{int foo (int count, int key)}
+@end example
+
+@noindent
+where @var{count} is the numeric argument (or 1 if defaulted) and
+@var{key} is the key that invoked this function.
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+A command function should return 0 if its action completes successfully,
+and a non-zero value if some error occurs.
+
+@node Readline Variables
+@section Readline Variables
+
+These variables are available to function writers.
+
+@deftypevar {char *} rl_line_buffer
+This is the line gathered so far.  You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}.  The
+function @code{rl_extend_line_buffer} is available to increase
+the memory allocated to @code{rl_line_buffer}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}.  When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The @var{mark} (saved position) in the current line.  If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+@end deftypevar
+
+@deftypevar int rl_num_chars_to_read
+Setting this to a positive value before calling @code{readline()} causes
+Readline to return after accepting that many characters, rather
+than reading up to a character bound to @code{accept-line}.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read.  This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar int rl_dispatching
+Set to a non-zero value if a function is being called from a key binding;
+zero otherwise.  Application functions can test this to discover whether
+they were called directly or by Readline's dispatching mechanism.
+@end deftypevar
+
+@deftypevar int rl_erase_empty_line
+Setting this to a non-zero value causes Readline to completely erase
+the current line, including any prompt, any time a newline is typed as
+the only character on an otherwise-empty line.  The cursor is moved to
+the beginning of the newly-blank line.
+@end deftypevar
+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses.  This is set from the argument to
+@code{readline()}, and should not be assigned to directly.
+The @code{rl_set_prompt()} function (@pxref{Redisplay}) may
+be used to modify the prompt string after calling @code{readline()}.
+@end deftypevar
+
+@deftypevar int rl_already_prompted
+If an application wishes to display the prompt itself, rather than have
+Readline do it the first time @code{readline()} is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to @code{readline()} so
+the redisplay functions can update the display properly.
+The calling application is responsible for managing the value; Readline
+never sets it.
+@end deftypevar
+
+@deftypevar {const char *} rl_library_version
+The version number of this revision of the library.
+@end deftypevar
+
+@deftypevar int rl_readline_version
+An integer encoding the current version of the library.  The encoding is
+of the form 0x@var{MMmm}, where @var{MM} is the two-digit major version
+number, and @var{mm} is the two-digit minor version number.
+For example, for Readline-4.2, @code{rl_readline_version} would have the
+value 0x0402.
+@end deftypevar
+
+@deftypevar {int} rl_gnu_readline_p
+Always set to 1, denoting that this is @sc{gnu} readline rather than some
+emulation.
+@end deftypevar
+
+@deftypevar {const char *} rl_terminal_name
+The terminal type, used for initialization.  If not set by the application,
+Readline sets this to the value of the @env{TERM} environment variable
+the first time it is called.
+@end deftypevar
+
+@deftypevar {const char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file
+(@pxref{Conditional Init Constructs}).
+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+If @code{NULL}, Readline defaults to @var{stdin}.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+If @code{NULL}, Readline defaults to @var{stdout}.
+@end deftypevar
+
+@deftypevar {rl_command_func_t *} rl_last_func
+The address of the last command function Readline executed.  May be used to
+test whether or not a function is being executed twice in succession, for
+example.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_startup_hook
+If non-zero, this is the address of a function to call just
+before @code{readline} prints the first prompt.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_pre_input_hook
+If non-zero, this is the address of a function to call after
+the first prompt has been printed and just before @code{readline}
+starts reading input characters.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_event_hook
+If non-zero, this is the address of a function to call periodically
+when Readline is waiting for terminal input.
+By default, this will be called at most ten times a second if there
+is no keyboard input.
+@end deftypevar
+
+@deftypevar {rl_getc_func_t *} rl_getc_function
+If non-zero, Readline will call indirectly through this pointer
+to get a character from the input stream.  By default, it is set to
+@code{rl_getc}, the default Readline character input function
+(@pxref{Character Input}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_redisplay_function
+If non-zero, Readline will call indirectly through this pointer
+to update the display with the current contents of the editing buffer.
+By default, it is set to @code{rl_redisplay}, the default Readline
+redisplay function (@pxref{Redisplay}).
+@end deftypevar
+
+@deftypevar {rl_vintfunc_t *} rl_prep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to initialize the terminal.  The function takes a single argument, an
+@code{int} flag that says whether or not to use eight-bit characters.
+By default, this is set to @code{rl_prep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_deprep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to reset the terminal.  This function should undo the effects of
+@code{rl_prep_term_function}.
+By default, this is set to @code{rl_deprep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {Keymap} rl_executing_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+currently executing readline function was found.
+@end deftypevar 
+
+@deftypevar {Keymap} rl_binding_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+last key binding occurred.
+@end deftypevar 
+
+@deftypevar {char *} rl_executing_macro
+This variable is set to the text of any currently-executing macro.
+@end deftypevar
+
+@deftypevar {int} rl_readline_state
+A variable with bit values that encapsulate the current Readline state.
+A bit is set with the @code{RL_SETSTATE} macro, and unset with the
+@code{RL_UNSETSTATE} macro.  Use the @code{RL_ISSTATE} macro to test
+whether a particular state bit is set.  Current state bits include:

+
+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+
+@example
+Meta-Rubout:	backward-kill-word
+@end example
+
+This binds the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+Add @var{name} to the list of named functions.  Make @var{function} be
+the function that gets called.  If @var{key} is not -1, then bind it to
+@var{function} using @code{rl_bind_key()}.
+@end deftypefun
+
+Using this function alone is sufficient for most applications.  It is
+the recommended way to add a few functions to the default functions that
+Readline has built in.  If you need to do something other
+than adding a function to Readline, you may need to use the
+underlying functions described below.
+
+@node Keymaps
+@subsection Selecting a Keymap
+
+Key bindings take place on a @dfn{keymap}.  The keymap is the
+association between the keys that the user types and the functions that
+get run.  You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+@deftypefun Keymap rl_make_bare_keymap (void)
+Returns a new, empty keymap.  The space for the keymap is allocated with
+@code{malloc()}; the caller should free it by calling
+@code{rl_discard_keymap()} when done.
+@end deftypefun
+
+@deftypefun Keymap rl_copy_keymap (Keymap map)
+Return a new keymap which is a copy of @var{map}.
+@end deftypefun
+
+@deftypefun Keymap rl_make_keymap (void)
+Return a new keymap with the printing characters bound to rl_insert,
+the lowercase Meta characters bound to run their equivalents, and
+the Meta digits bound to produce numeric arguments.
+@end deftypefun
+
+@deftypefun void rl_discard_keymap (Keymap keymap)
+Free the storage associated with @var{keymap}.
+@end deftypefun
+
+Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap (void)
+Returns the currently active keymap.
+@end deftypefun
+
+@deftypefun void rl_set_keymap (Keymap keymap)
+Makes @var{keymap} the currently active keymap.
+@end deftypefun
+
+@deftypefun Keymap rl_get_keymap_by_name (const char *name)
+Return the keymap matching @var{name}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
+Return the name matching @var{keymap}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@node Binding Keys
+@subsection Binding Keys
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+Since @code{readline()} installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to @code{readline()} will be overridden.
+An alternate mechanism is to install custom key bindings in an
+initialization function assigned to the @code{rl_startup_hook} variable
+(@pxref{Readline Variables}).
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, rl_command_func_t *function)
+Binds @var{key} to @var{function} in the currently active keymap.
+Returns non-zero in the case of an invalid @var{key}.
+@end deftypefun
+
+@deftypefun int rl_bind_key_in_map (int key, rl_command_func_t *function, Keymap map)
+Bind @var{key} to @var{function} in @var{map}.  Returns non-zero in the case
+of an invalid @var{key}.
+@end deftypefun
+
+@deftypefun int rl_unbind_key (int key)
+Bind @var{key} to the null function in the currently active keymap.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_key_in_map (int key, Keymap map)
+Bind @var{key} to the null function in @var{map}.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_function_in_map (rl_command_func_t *function, Keymap map)
+Unbind all keys that execute @var{function} in @var{map}.

+Unbind all keys that are bound to @var{command} in @var{map}.
+@end deftypefun
+
+@deftypefun int rl_set_key (const char *keyseq, rl_command_func_t *function, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the function
+@var{function}.  This makes new keymaps as
+necessary.  The initial keymap in which to do bindings is @var{map}.
+@end deftypefun
+
+@deftypefun int rl_generic_bind (int type, const char *keyseq, char *data, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the arbitrary
+pointer @var{data}.  @var{type} says what kind of data is pointed to by
+@var{data}; this can be a function (@code{ISFUNC}), a macro
+(@code{ISMACR}), or a keymap (@code{ISKMAP}).  This makes new keymaps as
+necessary.  The initial keymap in which to do bindings is @var{map}.
+@end deftypefun

+@end deftypefun
+
+@node Allowing Undoing
+@subsection Allowing Undoing
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try
+something if you know you can undo it.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+The types of events that can be undone are:
+
+@smallexample
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end smallexample
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text.  That is, the undo code
+tells what to undo, not how to undo it.  @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+@deftypefun int rl_begin_undo_group (void)
+Begins saving undo information in a group construct.  The undo
+information usually comes from calls to @code{rl_insert_text()} and
+@code{rl_delete_text()}, but could be the result of calls to
+@code{rl_add_undo()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group (void)
+Closes the current undo group started with @code{rl_begin_undo_group
+()}.  There should be one call to @code{rl_end_undo_group()}
+for each call to @code{rl_begin_undo_group()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}).  The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void rl_free_undo_list (void)
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo (void)
+Undo the first thing on the undo list.  Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call @code{rl_modifying()}
+once, just before you modify the text.  You must supply the indices of
+the text range that you are going to modify.
+
+@deftypefun int rl_modifying (int start, int end)
+Tell Readline to save the text between @var{start} and @var{end} as a
+single undo unit.  It is assumed that you will subsequently modify
+that text.
+@end deftypefun
+
+@node Redisplay
+@subsection Redisplay

+themselves, but still need Readline to know the prompt string length for
+redisplay.
+It should be used after setting @var{rl_already_prompted}.

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline()} was called, reset the signal handling to what it was
+before @code{readline()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state()} below).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}).  The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size information, and then calls
+any @code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal()} (described below), to restore the
+terminal state. 
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling @code{readline()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.
+
+@deftypevar int rl_catch_signals
+If this variable is non-zero, Readline will install signal handlers for
+@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM},
+@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}.
+
+The default value of @code{rl_catch_signals} is 1.
+@end deftypevar
+
+@deftypevar int rl_catch_sigwinch
+If this variable is non-zero, Readline will install a signal handler for
+@code{SIGWINCH}.
+
+The default value of @code{rl_catch_sigwinch} is 1.
+@end deftypevar

+If an application does not wish to have Readline catch any signals, or
+to handle signals other than those Readline catches (@code{SIGHUP},
+for example), 
+Readline provides convenience functions to do the necessary terminal
+and internal state cleanup upon receipt of a signal.
+
+@deftypefun void rl_cleanup_after_signal (void)

+@end deftypefun
+
+@deftypefun void rl_free_line_state (void)
+This will free any partial state associated with the current input line
+(undo information, any partial history entry, any partially-entered
+keyboard macro, and any partially-entered numeric argument).  This
+should be called before @code{rl_cleanup_after_signal()}.  The
+Readline signal handler for @code{SIGINT} calls this to abort the
+current input line.
+@end deftypefun
+
+@deftypefun void rl_reset_after_signal (void)
+This will reinitialize the terminal and reinstall any Readline signal
+handlers, depending on the values of @code{rl_catch_signals} and

+@end deftypefun
+
+If an application does not wish Readline to catch @code{SIGWINCH}, it may
+call @code{rl_resize_terminal()} or @code{rl_set_screen_size()} to force

+is received.

+
+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+
+There are three major functions used to perform completion:
+
+@enumerate
+@item
+The user-interface function @code{rl_complete()}.  This function is
+called with the same arguments as other bindable Readline functions:
+@var{count} and @var{invoking_key}.
+It isolates the word to be completed and calls
+@code{rl_completion_matches()} to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+@item
+The internal function @code{rl_completion_matches()} uses an
+application-supplied @dfn{generator} function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+@code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{rl_completion_matches()}, returning a string each time.  The
+arguments to the generator function are @var{text} and @var{state}.
+@var{text} is the partial word to be completed.  @var{state} is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when @var{state} is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with @code{malloc()}; Readline
+frees the strings when it has finished with them.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()}).  The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+This is a pointer to the generator function for
+@code{rl_completion_matches()}.
+If the value of @code{rl_completion_entry_function} is
+@code{NULL} then the default filename generator
+function, @code{rl_filename_completion_function()}, is used.

+Readline.
+

+insert all of the possible completions.  @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion.
+@end deftypefun

+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see

+@end deftypefun

+This calls @code{rl_complete_internal()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
+Returns the apppriate value to pass to @code{rl_complete_internal()}
+depending on whether @var{cfunc} was called twice in succession and
+the value of the @code{show-all-if-ambiguous} variable.
+Application-specific completion functions may use this function to present

+@end deftypefun
+
+@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
+Returns an array of strings which is a list of completions for

+@var{entry_func} is a function of two args, and returns a
+@code{char *}.  The first argument is @var{text}.  The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls.  @var{entry_func} returns a @code{NULL}  pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
+A generator function for filename completion in the general case.
+@var{text} is a partial filename.
+The Bash source is a useful reference for writing custom
+completion functions (the Bash completion functions call this and other
+Readline functions).
+@end deftypefun
+
+@deftypefun {char *} rl_username_completion_function (const char *text, int state)
+A completion generator for usernames.  @var{text} contains a partial
+username preceded by a random character (usually @samp{~}).  As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+A pointer to the generator function for @code{rl_completion_matches()}.
+@code{NULL} means to use @code{rl_filename_completion_function()}, the default
+filename completer.
+@end deftypevar
+
+@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
+the boundaries of @var{text}, which is a character string.
+If this function exists and returns @code{NULL}, or if this variable is
+set to @code{NULL}, then @code{rl_complete()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the @code{rl_attempted_completion_over}
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+@end deftypevar
+
+@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an
+application-specific fashion.  This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename.  The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}.  The @var{text}
+is the filename to be quoted.  The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}.  Some functions use this to decide whether or not to
+insert a closing quote character.  The @var{quote_pointer} is a pointer
+to any opening quote character the user typed.  Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem.  It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character 
+that delimits the filename (usually @samp{'} or @samp{"}).  If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses.  The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line.  It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches[0]}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.  It is called with the address of a
+string (the current directory name) as an argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be displayed as part of the completion, replacing
+the directory portion of the pathname the user typed.
+It returns an integer that should be non-zero if the function modifies
+its directory argument.
+It could be used to expand symbolic links or shell variables in pathnames.
+@end deftypevar
+
+@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
+If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
+where @var{matches} is the array of matching strings,
+@var{num_matches} is the number of strings in that array, and
+@var{max_length} is the length of the longest string in that array.
+Readline provides a convenience function, @code{rl_display_match_list},
+that takes care of doing the display to Readline's output stream.  That
+function may be called from this hook.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_word_break_characters
+The basic list of characters that signal a break between words for the
+completer routine.  The default value of this variable is the characters
+which break words for completion in Bash:
+@code{" \t\n\"\\'`@@$><=;|&@{("}.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_quote_characters
+A list of quote characters which can cause a word break.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_word_break_characters
+The list of characters that signal a break between words for
+@code{rl_complete_internal()}.  The default list is the value of
+@code{rl_basic_word_break_characters}.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_quote_characters
+A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {const char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename.  The default is the null string.
+@end deftypevar
+
+@deftypevar {const char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call.  After that, we ask the user if she is sure
+she wants to see them all.  The default value is 100.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text.  The
+default is a space character (@samp{ }).  Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in custom completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_append
+If non-zero, @var{rl_completion_append_character} is not appended to
+matches at the end of the command line, as described above.  It is
+set to 0 before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_mark_symlink_dirs
+If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable @var{mark-directories} variable.
+This variable exists so that application completion functions can
+override the user's global preference (set via the
+@var{mark-symlinked-directories} Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application completion function is called, so unless that function
+modifies the value, the user's preferences are honored.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then duplicates in the matches are removed.
+The default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames.  This is @emph{always} zero on entry, and can only be changed
+within a completion entry generator function.  If it is set to a non-zero
+value, directory names have a slash appended and Readline attempts to
+quote completed filenames if they contain any characters in
+@code{rl_filename_quote_characters} and @code{rl_filename_quoting_desired}
+is set to a non-zero value.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}.  This is @emph{always} non-zero
+on entry, and can only be changed within a completion entry generator
+function.  The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_attempted_completion_over
+If an application-specific completion function assigned to
+@code{rl_attempted_completion_function} sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+@end deftypevar
+
+@deftypevar int rl_completion_type
+Set to a character describing the type of completion Readline is currently
+attempting; see the description of @code{rl_complete_internal()}
+(@pxref{Completion Functions}) for the list of characters.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibited.  The completion
+character will be inserted as any other bound to @code{self-insert}.
+@end deftypevar

+@section Programmable Completion
+@cindex programmable completion
+
+When word completion is attempted for an argument to a command for
+which a completion specification (a @var{compspec}) has been defined
+using the @code{complete} builtin (@pxref{Programmable Completion Builtins}),
+the programmable completion facilities are invoked. 
+
+First, the command name is identified.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default Bash completion
+described above (@pxref{Commands For Completion}) is performed.
+
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the @option{-f} or @option{-d} option is used for filename or
+directory name completion, the shell variable @env{FIGNORE} is
+used to filter the matches.
+@xref{Bash Variables}, for a description of @env{FIGNORE}.
+
+Any completions specified by a filename expansion pattern to the
+@option{-G} option are generated next.
+The words generated by the pattern need not match the word being completed.
+The @env{GLOBIGNORE} shell variable is not used to filter the matches,
+but the @env{FIGNORE} shell variable is used.
+
+Next, the string specified as the argument to the @option{-W} option
+is considered.
+The string is first split using the characters in the @env{IFS}
+special variable as delimiters.
+Shell quoting is honored.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, arithmetic expansion, and pathname expansion,
+as described above (@pxref{Shell Expansions}).
+The results are split using the rules described above
+(@pxref{Word Splitting}).
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+
+After these matches have been generated, any shell function or command
+specified with the @option{-F} and @option{-C} options is invoked.
+When the command or function is invoked, the @env{COMP_LINE} and
+@env{COMP_POINT} variables are assigned values as described above
+(@pxref{Bash Variables}).
+If a shell function is being invoked, the @env{COMP_WORDS} and
+@env{COMP_CWORD} variables are also set.
+When the function or command is invoked, the first argument is the
+name of the command whose arguments are being completed, the
+second argument is the word being completed, and the third argument
+is the word preceding the word being completed on the current command line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+Any function specified with @option{-F} is invoked first.
+The function may use any of the shell facilities, including the
+@code{compgen} builtin described below
+(@pxref{Programmable Completion Builtins}), to generate the matches.
+It must put the possible completions in the @env{COMPREPLY} array
+variable.
+
+Next, any command specified with the @option{-C} option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to
+the standard output.
+Backslash may be used to escape a newline, if necessary.
+
+After all of the possible completions are generated, any filter
+specified with the @option{-X} option is applied to the list.
+The filter is a pattern as used for pathname expansion; a @samp{&}
+in the pattern is replaced with the text of the word being completed.
+A literal @samp{&} may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading @samp{!} negates the pattern; in this case any completion
+not matching the pattern will be removed.
+
+Finally, any prefix and suffix specified with the @option{-P} and @option{-S}
+options are added to each member of the completion list, and the result is
+returned to the Readline completion code as the list of possible
+completions.
+
+If the previously-applied actions do not generate any matches, and the
+@option{-o dirnames} option was supplied to @code{complete} when the
+compspec was defined, directory name completion is attempted. 
+
+By default, if a compspec is found, whatever it generates is returned to
+the completion code as the full set of possible completions.
+The default Bash completions are not attempted, and the Readline default
+of filename completion is disabled.
+If the @option{-o default} option was supplied to @code{complete} when the
+compspec was defined, Readline's default completion will be performed
+if the compspec generates no matches.
+
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the @var{mark-directories} Readline variable, regardless
+of the setting of the @var{mark-symlinked-directories} Readline variable.
+
+@node Programmable Completion Builtins
+@section Programmable Completion Builtins
+@cindex completion builtins
+
+Two builtin commands are available to manipulate the programmable completion
+facilities.
+
+@table @code
+@item compgen
+@btindex compgen
+@example
+@code{compgen [@var{option}] [@var{word}]}
+@end example
+
+Generate possible completion matches for @var{word} according to
+the @var{option}s, which may be any option accepted by the
+@code{complete}
+builtin with the exception of @option{-p} and @option{-r}, and write
+the matches to the standard output.
+When using the @option{-F} or @option{-C} options, the various shell variables
+set by the programmable completion facilities, while available, will not
+have useful values.
+
+The matches will be generated in the same way as if the programmable
+completion code had generated them directly from a completion specification
+with the same flags.
+If @var{word} is specified, only those completions matching @var{word}
+will be displayed.
+
+The return value is true unless an invalid option is supplied, or no
+matches were generated.
+
+@item complete
+@btindex complete
+@example
+@code{complete [-abcdefgjksuv] [-o @var{comp-option}] [-A @var{action}] [-G @var{globpat}] [-W @var{wordlist}]
+[-P @var{prefix}] [-S @var{suffix}] [-X @var{filterpat}] [-F @var{function}]
+[-C @var{command}] @var{name} [@var{name} @dots{}]}
+@code{complete -pr [@var{name} @dots{}]}
+@end example
+
+Specify how arguments to each @var{name} should be completed.
+If the @option{-p} option is supplied, or if no options are supplied, existing
+completion specifications are printed in a way that allows them to be
+reused as input.
+The @option{-r} option removes a completion specification for
+each @var{name}, or, if no @var{name}s are supplied, all
+completion specifications.
+
+The process of applying these completion specifications when word completion
+is attempted is described above (@pxref{Programmable Completion}).
+
+Other options, if specified, have the following meanings.
+The arguments to the @option{-G}, @option{-W}, and @option{-X} options
+(and, if necessary, the @option{-P} and @option{-S} options)
+should be quoted to protect them from expansion before the
+@code{complete} builtin is invoked.
+
+
+@table @code
+@item -o @var{comp-option}
+The @var{comp-option} controls several aspects of the compspec's behavior
+beyond the simple generation of completions.
+@var{comp-option} may be one of: 
+
+@table @code
+
+@item default
+Use Readline's default filename completion if the compspec generates
+no matches.
+
+@item dirnames
+Perform directory name completion if the compspec generates no matches.
+
+@item filenames
+Tell Readline that the compspec generates filenames, so it can perform any
+filename\-specific processing (like adding a slash to directory names or
+suppressing trailing spaces).  This option is intended to be used with
+shell functions specified with @option{-F}.
+
+@item nospace
+Tell Readline not to append a space (the default) to words completed at
+the end of the line.
+@end table
+
+@item -A @var{action}
+The @var{action} may be one of the following to generate a list of possible
+completions:
+
+@table @code
+@item alias
+Alias names.  May also be specified as @option{-a}.
+
+@item arrayvar
+Array variable names.
+
+@item binding
+Readline key binding names (@pxref{Bindable Readline Commands}).
+
+@item builtin
+Names of shell builtin commands.  May also be specified as @option{-b}.
+
+@item command
+Command names.  May also be specified as @option{-c}.
+
+@item directory
+Directory names.  May also be specified as @option{-d}.
+
+@item disabled
+Names of disabled shell builtins.
+
+@item enabled
+Names of enabled shell builtins.
+
+@item export
+Names of exported shell variables.  May also be specified as @option{-e}.
+
+@item file
+File names.  May also be specified as @option{-f}.
+
+@item function
+Names of shell functions.
+
+@item group
+Group names.  May also be specified as @option{-g}.
+
+@item helptopic
+Help topics as accepted by the @code{help} builtin (@pxref{Bash Builtins}).
+
+@item hostname
+Hostnames, as taken from the file specified by the
+@env{HOSTFILE} shell variable (@pxref{Bash Variables}).
+
+@item job
+Job names, if job control is active.  May also be specified as @option{-j}.
+
+@item keyword
+Shell reserved words.  May also be specified as @option{-k}.
+
+@item running
+Names of running jobs, if job control is active.
+
+@item service
+Service names.  May also be specified as @option{-s}.
+
+@item setopt
+Valid arguments for the @option{-o} option to the @code{set} builtin
+(@pxref{The Set Builtin}).
+
+@item shopt
+Shell option names as accepted by the @code{shopt} builtin
+(@pxref{Bash Builtins}).
+
+@item signal
+Signal names.
+
+@item stopped
+Names of stopped jobs, if job control is active.
+
+@item user
+User names.  May also be specified as @option{-u}.
+
+@item variable
+Names of all shell variables.  May also be specified as @option{-v}.
+@end table
+
+@item -G @var{globpat}
+The filename expansion pattern @var{globpat} is expanded to generate
+the possible completions.
+
+@item -W @var{wordlist}
+The @var{wordlist} is split using the characters in the
+@env{IFS} special variable as delimiters, and each resultant word
+is expanded.
+The possible completions are the members of the resultant list which
+match the word being completed.
+
+@item -C @var{command}
+@var{command} is executed in a subshell environment, and its output is
+used as the possible completions.
+
+@item -F @var{function}
+The shell function @var{function} is executed in the current shell
+environment.
+When it finishes, the possible completions are retrieved from the value
+of the @env{COMPREPLY} array variable.
+
+@item -X @var{filterpat}
+@var{filterpat} is a pattern as used for filename expansion.
+It is applied to the list of possible completions generated by the
+preceding options and arguments, and each completion matching
+@var{filterpat} is removed from the list.
+A leading @samp{!} in @var{filterpat} negates the pattern; in this
+case, any completion not matching @var{filterpat} is removed.
+
+@item -P @var{prefix}
+@var{prefix} is added at the beginning of each possible completion
+after all other options have been applied.
+
+@item -S @var{suffix}
+@var{suffix} is appended to each possible completion
+after all other options have been applied.
+@end table
+
+The return value is true unless an invalid option is supplied, an option
+other than @option{-p} or @option{-r} is supplied without a @var{name}
+argument, an attempt is made to remove a completion specification for
+a @var{name} for which no specification exists, or
+an error occurs adding a completion specification.

+
+Run each Texinfo or LaTeX FILE through TeX in turn until all
+cross-references are resolved, building all indices.  The directory
+containing each FILE is searched for included files.  The suffix of FILE
+is used to determine its language (LaTeX or Texinfo).
+
+Makeinfo is used to perform Texinfo macro expansion before running TeX
+when needed.
+
+Options:
+  -@                   Use @input instead of \input; for preloaded Texinfo.
+  -b, --batch          No interaction.
+  -c, --clean          Remove all auxiliary files.
+  -D, --debug          Turn on shell debugging (set -x).
+  -e, --expand         Force macro expansion using makeinfo.
+  -I DIR               Search DIR for Texinfo files.
+  -h, --help           Display this help and exit successfully.
+  -l, --language=LANG  Specify the LANG of FILE: LaTeX or Texinfo.
+  -p, --pdf            Use pdftex or pdflatex for processing.
+  -q, --quiet          No output unless errors (implies --batch).
+  -s, --silent         Same as --quiet.
+  -t, --texinfo=CMD    Insert CMD after @setfilename in copy of input file.
+                       Multiple values accumulate.
+  -v, --version        Display version information and exit successfully.

+#     some global string/hash/array variables
+# 2.) For larger changes, reimplement one of the T2H_DEFAULT_<fnc>* routines,
+#     give them another name, and assign them to the respective
+#     $T2H_<fnc> variable.
+
+# As a general interface, the hashes T2H_HREF, T2H_NAME, T2H_NODE hold 
+# href, html-name, node-name of
+# This     -- current section (resp. html page)
+# Top      -- top page ($T2H_TOP_FILE)
+# Contents -- Table of contents
+# Overview -- Short table of contents
+# Index    -- Index page
+# About    -- page which explain "navigation buttons"
+# First    -- first node 
+# Last     -- last node
+#
+# Whether or not the following hash values are set, depends on the context 
+# (all values are w.r.t. 'This' section)
+# Next        -- next node of texinfo
+# Prev        -- previous node of texinfo
+# Up          -- up node of texinfo

+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o # or whatever, to process the dvi file; this makes foo.ps.
+% The extra runs of TeX get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages.  You can get
+% the existing language-specific files from ftp://ftp.gnu.org/gnu/texinfo/.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+%
+% For those who want to use more than one line's worth of words in
+% the preamble, break the line within one argument and it
+% will parse correctly, i.e.,
+%
+%     @multitable {Column 1 template} {Column 2 template} {Column 3
+%      template}
+% Not:
+%     @multitable {Column 1 template} {Column 2 template}
+%      {Column 3 template}
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab, @multitable or @end multitable do not need to be on their
+% own lines, but it will not hurt if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+Subject: new readline example
+Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
+
+Chet,
+
+I've been using readline 4.0. Specifically, I've been using the perl
+version Term::ReadLine::Gnu. It works great.
+
+Anyway, I've been playing around the alternate interface and I wanted
+to contribute a little C program, callback.c, to you that you could
+use as an example of the alternate interface in the /examples
+directory of the readline distribution.
+
+My example shows how, using the alternate interface, you can
+interactively change the prompt (which is very nice imo). Also, I
+point out that you must roll your own terminal setting when using the
+alternate interface because readline depreps (using your parlance) the
+terminal while in the user callback. I try to demostrate what I mean
+with an example. I've included the program below.
+
+To compile, I just put the program in the examples directory and made
+the appropriate changes to the EXECUTABLES and OBJECTS line and added
+an additional target 'callback'.
+
+I compiled on my Sun Solaris2.6 box using Sun's cc.
+
+Let me know what you think.
+

+/* This little examples demonstrates the alternate interface to using readline.
+ * In the alternate interface, the user maintains control over program flow and
+ * only calls readline when STDIN is readable. Using the alternate interface,
+ * you can do anything else while still using readline (like talking to a
+ * network or another program) without blocking.
+ *
+ * Specifically, this program highlights two importants features of the
+ * alternate interface. The first is the ability to interactively change the
+ * prompt, which can't be done using the regular interface since rl_prompt is
+ * read-only.
+ * 
+ * The second feature really highlights a subtle point when using the alternate
+ * interface. That is, readline will not alter the terminal when inside your
+ * callback handler. So let's so, your callback executes a user command that
+ * takes a non-trivial amount of time to complete (seconds). While your
+ * executing the command, the user continues to type keystrokes and expects them
+ * to be re-echoed on the new prompt when it returns. Unfortunately, the default
+ * terminal configuration doesn't do this. After the prompt returns, the user
+ * must hit one additional keystroke and then will see all of his previous
+ * keystrokes. To illustrate this, compile and run this program. Type "sleep" at
+ * the prompt and then type "bar" before the prompt returns (you have 3
+ * seconds). Notice how "bar" is re-echoed on the prompt after the prompt
+ * returns? This is what you expect to happen. Now comment out the 4 lines below
+ * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do
+ * the same thing. When the prompt returns, you should not see "bar". Now type
+ * "f", see how "barf" magically appears? This behavior is un-expected and not
+ * desired.

+/* PROBLEMS/TODO:
+ *
+ * Only tested under Linux;  needs to be ported.
+ *
+ * When running mc -c under the Linux console, mc does not recognize
+ * mouse clicks, which mc does when not running under fep.
+ *
+ * Pasting selected text containing tabs is like hitting the tab character,
+ * which invokes readline completion.  We don't want this.  I don't know
+ * if this is fixable without integrating fep into a terminal emulator.
+ *
+ * Echo suppression is a kludge, but can only be avoided with better kernel
+ * support: We need a tty mode to disable "real" echoing, while still
+ * letting the inferior think its tty driver to doing echoing.
+ * Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
+ *
+ * The latest readline may have some hooks we can use to avoid having
+ * to back up the prompt.
+ *
+ * Desirable readline feature:  When in cooked no-echo mode (e.g. password),
+ * echo characters are they are types with '*', but remove them when done.
+ *
+ * A synchronous output while we're editing an input line should be
+ * inserted in the output view *before* the input line, so that the
+ * lines being edited (with the prompt) float at the end of the input.
+ *
+ * A "page mode" option to emulate more/less behavior:  At each page of
+ * output, pause for a user command.  This required parsing the output
+ * to keep track of line lengths.  It also requires remembering the
+ * output, if we want an option to scroll back, which suggests that
+ * this should be integrated with a terminal emulator like xterm.

+       Free Software Foundation, Inc.
+
+DDEESSCCRRIIPPTTIIOONN
+       Many programs read input from the user a line at  a  time.
+       The  GNU  History  library  is able to keep track of those
+       lines, associate arbitrary data with each line,  and  uti-
+       lize  information  from  previous  lines  in composing new
+       ones.
+
+
+HHIISSTTOORRYY EEXXPPAANNSSIIOONN
+       The history library supports a history  expansion  feature
+       that  is identical to the history expansion in bbaasshh..  This
+       section describes what syntax features are available.
+
+       History expansions introduce words from the  history  list
+       into  the input stream, making it easy to repeat commands,
+       insert the arguments to a previous command into  the  cur-
+       rent  input  line,  or  fix  errors  in  previous commands
+       quickly.
+
+       History expansion is usually performed immediately after a
+       complete  line is read.  It takes place in two parts.  The
+       first is to determine which line from the history list  to
+       use during substitution.  The second is to select portions
+       of that line for inclusion into the current one.  The line
+       selected  from  the history is the _e_v_e_n_t, and the portions
+       of that line that are acted upon are _w_o_r_d_s.  Various _m_o_d_i_-
+       _f_i_e_r_s are available to manipulate the selected words.  The
+       line is broken into words in the same fashion as bbaasshh does
+       when  reading input, so that several words that would oth-
+       erwise be separated are  considered  one  word  when  sur-
+       rounded  by  quotes  (see  the description of hhiissttoorryy__ttookk--
+       eenniizzee(()) below).  History expansions are introduced by  the
+       appearance  of the history expansion character, which is !!
+       by default.  Only backslash  (\\)  and  single  quotes  can
+       quote the history expansion character.
+
+   EEvveenntt DDeessiiggnnaattoorrss
+       An event designator is a reference to a command line entry
+       in the history list.
+
+       !!      Start a history substitution, except when  followed
+              by a bbllaannkk, newline, = or (.
+       !!_n     Refer to command line _n.
+       !!--_n    Refer to the current command line minus _n.
+       !!!!     Refer  to  the previous command.  This is a synonym
+              for `!-1'.

+       Word designators are used to select desired words from the
+       event.  A :: separates the  event  specification  from  the
+       word designator.  It may be omitted if the word designator
+       begins with a ^^, $$, **, --, or %%.  Words are  numbered  from
+       the  beginning  of  the  line,  with  the first word being
+       denoted by 0 (zero).  Words are inserted into the  current
+       line separated by single spaces.
+
+       00 ((zzeerroo))
+              The  zeroth  word.  For the shell, this is the com-
+              mand word.
+       _n      The _nth word.
+       ^^      The first argument.  That is, word 1.
+       $$      The last argument.
+       %%      The word matched  by  the  most  recent  `?_s_t_r_i_n_g?'
+              search.
+       _x--_y    A range of words; `-_y' abbreviates `0-_y'.
+       **      All of the words but the zeroth.  This is a synonym
+              for `_1_-_$'.  It is not an error to use ** if there is
+              just  one  word  in  the event; the empty string is
+              returned in that case.
+       xx**     Abbreviates _x_-_$.
+       xx--     Abbreviates _x_-_$ like xx**, but omits the last word.
+
+       If a word designator is supplied without an event specifi-
+       cation, the previous command is used as the event.
+
+   MMooddiiffiieerrss
+       After  the  optional  word  designator, there may appear a

+       This section describes how to use the History  library  in
+       other programs.
+
+   IInnttrroodduuccttiioonn ttoo HHiissttoorryy
+       The  programmer  using  the  History library has available
+       functions for remembering lines on a history list, associ-
+       ating  arbitrary data with a line, removing lines from the
+       list, searching through the list for a line containing  an
+       arbitrary  text  string,  and  referencing any line in the
+       list directly.  In addition, a history _e_x_p_a_n_s_i_o_n  function
+       is  available  which provides for a consistent user inter-
+       face across different programs.
+
+       The user using programs written with the  History  library
+       has  the benefit of a consistent user interface with a set
+       of well-known commands for manipulating the text of previ-
+       ous  lines and using that text in new commands.  The basic
+       history manipulation commands are identical to the history
+       substitution provided by bbaasshh.
+
+       If  the  programmer  desires,  he  can  use  the  Readline
+       library,  which  includes  some  history  manipulation  by
+       default, and has the added advantage of command line edit-
+       ing.
+

+       tory entry is declared as follows:
+
+       _t_y_p_e_d_e_f _v_o_i_d _* hhiissttddaattaa__tt;;
+
+       typedef struct _hist_entry {

+
+       _H_I_S_T___E_N_T_R_Y _*_* tthhee__hhiissttoorryy__lliisstt;;
+
+       The  state  of  the History library is encapsulated into a
+       single structure:
+
+       /*
+        * A structure used to pass around the current state of the history.
+        */
+       typedef struct _hist_state {

+<H2> 1.1 History Expansion </H2>
+<!--docid::SEC2::-->
+<P>
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by <CODE>csh</CODE>.  This section
+describes the syntax used to manipulate the history information.
+</P><P>
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+</P><P>
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+<EM>event</EM>, and the portions of that line that are acted upon are
+called <EM>words</EM>.  Various <EM>modifiers</EM> are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is <SAMP>`!'</SAMP> by default.

+<!--docid::SEC7::-->
+<P>
+
+Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+</P><P>
+
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history <EM>expansion</EM> function
+is available which provides for a consistent user interface across
+different programs.
+</P><P>
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by <CODE>csh</CODE>.
+</P><P>
+
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+</P><P>
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file <CODE>&#60;readline/history.h&#62;</CODE> in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.

+
+History Expansion
+=================
+
+   The History library provides a history expansion feature that is
+similar to the history expansion provided by `csh'.  This section
+describes the syntax used to manipulate the history information.
+
+   History expansions introduce words from the history list into the
+input stream, making it easy to repeat commands, insert the arguments
+to a previous command into the current input line, or fix errors in
+previous commands quickly.
+
+   History expansion takes place in two parts.  The first is to
+determine which line from the history list should be used during
+substitution.  The second is to select portions of that line for
+inclusion into the current one.  The line selected from the history is
+called the "event", and the portions of that line that are acted upon
+are called "words".  Various "modifiers" are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words surrounded by quotes are
+considered one word.  History expansions are introduced by the
+appearance of the history expansion character, which is `!' by default.

+

+File: history.info,  Node: Event Designators,  Next: Word Designators,  Up: History Interaction
+
+Event Designators
+-----------------
+
+   An event designator is a reference to a command line entry in the
+history list.
+
+`!'
+     Start a history substitution, except when followed by a space, tab,
+     the end of the line, `=' or `('.
+
+`!N'
+     Refer to command line N.
+
+`!-N'
+     Refer to the command N lines back.
+
+`!!'
+     Refer to the previous command.  This is a synonym for `!-1'.
+
+`!STRING'
+     Refer to the most recent command starting with STRING.
+
+`!?STRING[?]'
+     Refer to the most recent command containing STRING.  The trailing
+     `?' may be omitted if the STRING is followed immediately by a
+     newline.
+
+`^STRING1^STRING2^'
+     Quick Substitution.  Repeat the last command, replacing STRING1
+     with STRING2.  Equivalent to `!!:s/STRING1/STRING2/'.
+
+`!#'
+     The entire command line typed so far.
+
+
+File: history.info,  Node: Word Designators,  Next: Modifiers,  Prev: Event Designators,  Up: History Interaction
+
+Word Designators
+----------------
+
+   Word designators are used to select desired words from the event.  A
+`:' separates the event specification from the word designator.  It may
+be omitted if the word designator begins with a `^', `$', `*', `-', or
+`%'.  Words are numbered from the beginning of the line, with the first
+word being denoted by 0 (zero).  Words are inserted into the current
+line separated by single spaces.
+
+   For example,
+
+`!!'
+     designates the preceding command.  When you type this, the
+     preceding command is repeated in toto.
+
+`!!:$'
+     designates the last argument of the preceding command.  This may be
+     shortened to `!$'.
+
+`!fi:2'
+     designates the second argument of the most recent command starting
+     with the letters `fi'.
+
+   Here are the word designators:
+
+`0 (zero)'
+     The `0'th word.  For many applications, this is the command word.
+
+`N'
+     The Nth word.
+
+`^'
+     The first argument; that is, word 1.
+
+`$'
+     The last argument.
+
+`%'
+     The word matched by the most recent `?STRING?' search.
+
+`X-Y'
+     A range of words; `-Y' abbreviates `0-Y'.
+
+`*'
+     All of the words, except the `0'th.  This is a synonym for `1-$'.
+     It is not an error to use `*' if there is just one word in the
+     event; the empty string is returned in that case.
+
+`X*'
+     Abbreviates `X-$'
+
+`X-'
+     Abbreviates `X-$' like `X*', but omits the last word.
+
+   If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+
+File: history.info,  Node: Modifiers,  Prev: Word Designators,  Up: History Interaction
+
+Modifiers
+---------
+
+   After the optional word designator, you can add a sequence of one or
+more of the following modifiers, each preceded by a `:'.
+
+`h'
+     Remove a trailing pathname component, leaving only the head.
+
+`t'
+     Remove all leading  pathname  components, leaving the tail.
+
+`r'
+     Remove a trailing suffix of the form `.SUFFIX', leaving the
+     basename.
+
+`e'
+     Remove all but the trailing suffix.
+
+`p'
+     Print the new command but do not execute it.
+
+`s/OLD/NEW/'
+     Substitute NEW for the first occurrence of OLD in the event line.
+     Any delimiter may be used in place of `/'.  The delimiter may be
+     quoted in OLD and NEW with a single backslash.  If `&' appears in
+     NEW, it is replaced by OLD.  A single backslash will quote the
+     `&'.  The final delimiter is optional if it is the last character
+     on the input line.
+
+`&'
+     Repeat the previous substitution.
+
+`g'
+     Cause changes to be applied over the entire event line.  Used in
+     conjunction with `s', as in `gs/OLD/NEW/', or with `&'.

+
+Introduction to History
+=======================
+
+   Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate
+arbitrary data with each line, and utilize information from previous
+lines in composing new ones.
+
+   The programmer using the History library has available functions for
+remembering lines on a history list, associating arbitrary data with a
+line, removing lines from the list, searching through the list for a
+line containing an arbitrary text string, and referencing any line in
+the list directly.  In addition, a history "expansion" function is
+available which provides for a consistent user interface across
+different programs.
+
+   The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by `csh'.
+
+   If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+   Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file `<readline/history.h>' in any file that uses the History
+library's features.  It supplies extern declarations for all of the
+library's public functions and variables, and declares all of the
+public data structures.
+
+
+File: history.info,  Node: History Storage,  Next: History Functions,  Prev: Introduction to History,  Up: Programming with GNU History
+
+History Storage
+===============
+
+   The history list is an array of history entries.  A history entry is
+declared as follows:
+
+     typedef void *histdata_t;
+     
+     typedef struct _hist_entry {
+       char *line;
+       histdata_t data;
+     } HIST_ENTRY;
+
+   The history list itself might therefore be declared as
+
+     HIST_ENTRY **the_history_list;
+
+   The state of the History library is encapsulated into a single
+structure:
+
+     /*
+      * A structure used to pass around the current state of the history.
+      */
+     typedef struct _hist_state {
+       HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+       int offset;           /* The location pointer within this array. */
+       int length;           /* Number of elements within this array. */
+       int size;             /* Number of slots allocated to this array. */
+       int flags;
+     } HISTORY_STATE;
+
+   If the flags member includes `HS_STIFLED', the history has been
+stifled.

+Initializing History and State Management
+-----------------------------------------
+
+   This section describes functions used to initialize and manage the
+state of the History library when you want to use the history functions
+in your program.
+
+ - Function: void using_history (void)
+     Begin a session in which the history functions might be used.  This
+     initializes the interactive variables.
+
+ - Function: HISTORY_STATE * history_get_history_state (void)
+     Return a structure describing the current state of the input
+     history.
+
+ - Function: void history_set_history_state (HISTORY_STATE *state)
+     Set the state of the history list according to STATE.
+
+
+File: history.info,  Node: History List Management,  Next: Information About the History List,  Prev: Initializing History and State Management,  Up: History Functions
+
+History List Management
+-----------------------
+
+   These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+ - Function: void add_history (const char *string)
+     Place STRING at the end of the history list.  The associated data
+     field (if any) is set to `NULL'.
+
+ - Function: HIST_ENTRY * remove_history (int which)
+     Remove history entry at offset WHICH from the history.  The
+     removed element is returned so you can free the line, data, and
+     containing structure.
+
+ - Function: HIST_ENTRY * replace_history_entry (int which, const char
+          *line, histdata_t data)
+     Make the history entry at offset WHICH have LINE and DATA.  This
+     returns the old entry so you can dispose of the data.  In the case
+     of an invalid WHICH, a `NULL' pointer is returned.
+
+ - Function: void clear_history (void)
+     Clear the history list by deleting all the entries.
+
+ - Function: void stifle_history (int max)
+     Stifle the history list, remembering only the last MAX entries.
+
+ - Function: int unstifle_history (void)
+     Stop stifling the history.  This returns the previously-set
+     maximum number of history entries (as set by `stifle_history()').
+     The value is positive if the history was stifled, negative if it
+     wasn't.
+
+ - Function: int history_is_stifled (void)
+     Returns non-zero if the history is stifled, zero if it is not.
+
+
+File: history.info,  Node: Information About the History List,  Next: Moving Around the History List,  Prev: History List Management,  Up: History Functions
+
+Information About the History List
+----------------------------------
+
+   These functions return information about the entire history list or
+individual list entries.
+
+ - Function: HIST_ENTRY ** history_list (void)
+     Return a `NULL' terminated array of `HIST_ENTRY *' which is the
+     current input history.  Element 0 of this list is the beginning of
+     time.  If there is no history, return `NULL'.
+
+ - Function: int where_history (void)
+     Returns the offset of the current history element.
+
+ - Function: HIST_ENTRY * current_history (void)
+     Return the history entry at the current position, as determined by
+     `where_history()'.  If there is no entry there, return a `NULL'
+     pointer.
+
+ - Function: HIST_ENTRY * history_get (int offset)
+     Return the history entry at position OFFSET, starting from
+     `history_base' (*note History Variables::).  If there is no entry
+     there, or if OFFSET is greater than the history length, return a
+     `NULL' pointer.
+
+ - Function: int history_total_bytes (void)
+     Return the number of bytes that the primary history entries are
+     using.  This function returns the sum of the lengths of all the
+     lines in the history.
+
+
+File: history.info,  Node: Moving Around the History List,  Next: Searching the History List,  Prev: Information About the History List,  Up: History Functions
+
+Moving Around the History List
+------------------------------
+
+   These functions allow the current index into the history list to be
+set or changed.
+
+ - Function: int history_set_pos (int pos)
+     Set the current history offset to POS, an absolute index into the
+     list.  Returns 1 on success, 0 if POS is less than zero or greater
+     than the number of history entries.
+
+ - Function: HIST_ENTRY * previous_history (void)
+     Back up the current history offset to the previous history entry,
+     and return a pointer to that entry.  If there is no previous
+     entry, return a `NULL' pointer.
+
+ - Function: HIST_ENTRY * next_history (void)
+     Move the current history offset forward to the next history entry,
+     and return the a pointer to that entry.  If there is no next
+     entry, return a `NULL' pointer.
+
+
+File: history.info,  Node: Searching the History List,  Next: Managing the History File,  Prev: Moving Around the History List,  Up: History Functions
+
+Searching the History List
+--------------------------
+
+   These functions allow searching of the history list for entries
+containing a specific string.  Searching may be performed both forward
+and backward from the current history position.  The search may be
+"anchored", meaning that the string must match at the beginning of the
+history entry.
+
+ - Function: int history_search (const char *string, int direction)
+     Search the history for STRING, starting at the current history
+     offset.  If DIRECTION is less than 0, then the search is through
+     previous entries, otherwise through subsequent entries.  If STRING
+     is found, then the current history index is set to that history
+     entry, and the value returned is the offset in the line of the
+     entry where STRING was found.  Otherwise, nothing is changed, and
+     a -1 is returned.
+
+ - Function: int history_search_prefix (const char *string, int
+          direction)
+     Search the history for STRING, starting at the current history
+     offset.  The search is anchored: matching lines must begin with
+     STRING.  If DIRECTION is less than 0, then the search is through
+     previous entries, otherwise through subsequent entries.  If STRING
+     is found, then the current history index is set to that entry, and
+     the return value is 0.  Otherwise, nothing is changed, and a -1 is
+     returned.
+
+ - Function: int history_search_pos (const char *string, int direction,
+          int pos)
+     Search for STRING in the history list, starting at POS, an
+     absolute index into the list.  If DIRECTION is negative, the search
+     proceeds backward from POS, otherwise forward.  Returns the
+     absolute index of the history element where STRING was found, or
+     -1 otherwise.
+
+
+File: history.info,  Node: Managing the History File,  Next: History Expansion,  Prev: Searching the History List,  Up: History Functions
+
+Managing the History File
+-------------------------
+
+   The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+ - Function: int read_history (const char *filename)
+     Add the contents of FILENAME to the history list, a line at a time.
+     If FILENAME is `NULL', then read from `~/.history'.  Returns 0 if
+     successful, or `errno' if not.
+
+ - Function: int read_history_range (const char *filename, int from,
+          int to)
+     Read a range of lines from FILENAME, adding them to the history
+     list.  Start reading at line FROM and end at TO.  If FROM is zero,
+     start at the beginning.  If TO is less than FROM, then read until
+     the end of the file.  If FILENAME is `NULL', then read from
+     `~/.history'.  Returns 0 if successful, or `errno' if not.
+
+ - Function: int write_history (const char *filename)
+     Write the current history to FILENAME, overwriting FILENAME if
+     necessary.  If FILENAME is `NULL', then write the history list to
+     `~/.history'.  Returns 0 on success, or `errno' on a read or write
+     error.
+
+ - Function: int append_history (int nelements, const char *filename)
+     Append the last NELEMENTS of the history list to FILENAME.  If
+     FILENAME is `NULL', then append to `~/.history'.  Returns 0 on
+     success, or `errno' on a read or write error.
+
+ - Function: int history_truncate_file (const char *filename, int
+          nlines)
+     Truncate the history file FILENAME, leaving only the last NLINES
+     lines.  If FILENAME is `NULL', then `~/.history' is truncated.
+     Returns 0 on success, or `errno' on failure.
+
+
+File: history.info,  Node: History Expansion,  Prev: Managing the History File,  Up: History Functions
+
+History Expansion
+-----------------
+
+   These functions implement history expansion.
+
+ - Function: int history_expand (char *string, char **output)
+     Expand STRING, placing the result into OUTPUT, a pointer to a
+     string (*note History Interaction::).  Returns:
+    `0'
+          If no expansions took place (or, if the only change in the
+          text was the removal of escape characters preceding the
+          history expansion character);
+
+    `1'
+          if expansions did take place;
+
+    `-1'
+          if there was an error in expansion;
+
+    `2'
+          if the returned line should be displayed, but not executed,
+          as with the `:p' modifier (*note Modifiers::).
+
+     If an error ocurred in expansion, then OUTPUT contains a
+     descriptive error message.
+
+ - Function: char * get_history_event (const char *string, int *cindex,
+          int qchar)
+     Returns the text of the history event beginning at STRING +
+     *CINDEX.  *CINDEX is modified to point to after the event
+     specifier.  At function entry, CINDEX points to the index into
+     STRING where the history event specification begins.  QCHAR is a
+     character that is allowed to end the event specification in
+     addition to the "normal" terminating characters.
+
+ - Function: char ** history_tokenize (const char *string)
+     Return an array of tokens parsed out of STRING, much as the shell
+     might.  The tokens are split on the characters in the
+     HISTORY_WORD_DELIMITERS variable, and shell quoting conventions
+     are obeyed.
+
+ - Function: char * history_arg_extract (int first, int last, const
+          char *string)
+     Extract a string segment consisting of the FIRST through LAST
+     arguments present in STRING.  Arguments are split using
+     `history_tokenize'.

+
+History Variables
+=================
+
+   This section describes the externally-visible variables exported by
+the GNU History Library.
+
+ - Variable: int history_base
+     The logical offset of the first entry in the history list.
+
+ - Variable: int history_length
+     The number of entries currently stored in the history list.
+
+ - Variable: int history_max_entries
+     The maximum number of history entries.  This must be changed using
+     `stifle_history()'.
+
+ - Variable: char history_expansion_char
+     The character that introduces a history event.  The default is `!'.
+     Setting this to 0 inhibits history expansion.
+
+ - Variable: char history_subst_char
+     The character that invokes word substitution if found at the start
+     of a line.  The default is `^'.
+
+ - Variable: char history_comment_char
+     During tokenization, if this character is seen as the first
+     character of a word, then it and all subsequent characters up to a
+     newline are ignored, suppressing history expansion for the
+     remainder of the line.  This is disabled by default.
+
+ - Variable: char * history_word_delimiters
+     The characters that separate tokens for `history_tokenize()'.  The
+     default value is `" \t\n()<>;&|"'.
+
+ - Variable: char * history_no_expand_chars
+     The list of characters which inhibit history expansion if found
+     immediately following HISTORY_EXPANSION_CHAR.  The default is
+     space, tab, newline, carriage return, and `='.
+
+ - Variable: char * history_search_delimiter_chars
+     The list of additional characters which can delimit a history
+     search string, in addition to space, TAB, `:' and `?' in the case
+     of a substring search.  The default is empty.
+
+ - Variable: int history_quotes_inhibit_expansion
+     If non-zero, single-quoted words are not scanned for the history
+     expansion character.  The default value is 0.
+
+ - Variable: rl_linebuf_func_t * history_inhibit_expansion_function
+     This should be set to the address of a function that takes two
+     arguments: a `char *' (STRING) and an `int' index into that string
+     (I).  It should return a non-zero value if the history expansion
+     starting at STRING[I] should not be performed; zero if the
+     expansion should be done.  It is intended for use by applications
+     like Bash that use the history expansion character for additional
+     purposes.  By default, this variable is set to `NULL'.

+       Foundation, Inc.
+
+DDEESSCCRRIIPPTTIIOONN
+       rreeaaddlliinnee will read a line from the terminal and return it,
+       using  pprroommpptt as a prompt.  If pprroommpptt is NNUULLLL or the empty
+       string, no prompt is issued.  The line returned  is  allo-
+       cated  with  _m_a_l_l_o_c(3);  the caller must free it when fin-
+       ished.  The line returned has the final  newline  removed,
+       so only the text of the line remains.
+
+       rreeaaddlliinnee  offers  editing  capabilities  while the user is
+       entering the line.  By default, the line editing  commands
+       are  similar  to  those of emacs.  A vi-style line editing
+       interface is also available.
+
+       This manual page describes only  the  most  basic  use  of
+       rreeaaddlliinnee.   Much  more functionality is available; see _T_h_e
+       _G_N_U _R_e_a_d_l_i_n_e _L_i_b_r_a_r_y and _T_h_e _G_N_U _H_i_s_t_o_r_y _L_i_b_r_a_r_y for addi-
+       tional information.
+
+RREETTUURRNN VVAALLUUEE
+       rreeaaddlliinnee  returns the text of the line read.  A blank line
+       returns the empty string.  If  EEOOFF  is  encountered  while
+       reading  a  line, and the line is empty, NNUULLLL is returned.
+       If an EEOOFF is read with a non-empty line, it is treated  as
+       a newline.
+
+NNOOTTAATTIIOONN
+       An  emacs-style  notation  is  used  to denote keystrokes.
+       Control keys are denoted by C-_k_e_y, e.g.,  C-n  means  Con-
+       trol-N.  Similarly, _m_e_t_a keys are denoted by M-_k_e_y, so M-x
+       means Meta-X.  (On keyboards without a _m_e_t_a key, M-_x means
+       ESC  _x,  i.e.,  press the Escape key then the _x key.  This
+       makes ESC the _m_e_t_a _p_r_e_f_i_x.  The  combination  M-C-_x  means
+       ESC-Control-_x,  or press the Escape key then hold the Con-
+       trol key while pressing the _x key.)
+
+       Readline commands may be given  numeric  _a_r_g_u_m_e_n_t_s,  which
+       normally act as a repeat count.  Sometimes, however, it is
+       the sign of the argument that is significant.   Passing  a
+       negative  argument  to  a command that acts in the forward
+       direction (e.g., kkiillll--lliinnee) causes that command to act  in
+       a  backward direction.  Commands whose behavior with argu-
+       ments deviates from this are noted.
+
+       When a command is described  as  _k_i_l_l_i_n_g  text,  the  text
+       deleted  is saved for possible future retrieval (_y_a_n_k_i_n_g).
+       The killed text is saved  in  a  _k_i_l_l  _r_i_n_g.   Consecutive
+       kills  cause  the  text  to  be accumulated into one unit,
+       which can be yanked all at once.  Commands  which  do  not
+       kill text separate the chunks of text on the kill ring.
+
+IINNIITTIIAALLIIZZAATTIIOONN FFIILLEE
+       Readline  is customized by putting commands in an initial-
+       ization file (the _i_n_p_u_t_r_c file).  The name of this file is
+       taken  from the value of the IINNPPUUTTRRCC environment variable.
+       If that variable is  unset,  the  default  is  _~_/_._i_n_p_u_t_r_c.
+       When  a program which uses the readline library starts up,
+       the init file is read, and the key bindings and  variables
+       are set.  There are only a few basic constructs allowed in
+       the readline init file.  Blank lines are  ignored.   Lines
+       beginning with a ## are comments.  Lines beginning with a $$
+       indicate conditional constructs.  Other lines  denote  key
+       bindings  and  variable settings.  Each program using this
+       library may add its own commands and bindings.
+
+       For example, placing
+
+              M-Control-u: universal-argument
+       or
+              C-Meta-u: universal-argument
+
+       into the _i_n_p_u_t_r_c would make  M-C-u  execute  the  readline
+       command _u_n_i_v_e_r_s_a_l_-_a_r_g_u_m_e_n_t.
+
+       The  following  symbolic  character  names  are recognized
+       while processing key bindings: _D_E_L, _E_S_C, _E_S_C_A_P_E, _L_F_D, _N_E_W_-
+       _L_I_N_E, _R_E_T, _R_E_T_U_R_N, _R_U_B_O_U_T, _S_P_A_C_E, _S_P_C, and _T_A_B.
+
+       In  addition  to command names, readline allows keys to be
+       bound to a string that is inserted when the key is pressed
+       (a _m_a_c_r_o).
+
+
+   KKeeyy BBiinnddiinnggss
+       The  syntax  for  controlling  key bindings in the _i_n_p_u_t_r_c
+       file is simple.  All that is required is the name  of  the
+       command or the text of a macro and a key sequence to which
+       it should be bound. The name may be specified  in  one  of
+       two  ways:  as a symbolic key name, possibly with _M_e_t_a_- or
+       _C_o_n_t_r_o_l_- prefixes, or as a key sequence.
+
+       When using the form kkeeyynnaammee:_f_u_n_c_t_i_o_n_-_n_a_m_e or  _m_a_c_r_o,  _k_e_y_-
+       _n_a_m_e  is  the  name  of a key spelled out in English.  For
+       example:
+
+              Control-u: universal-argument
+              Meta-Rubout: backward-kill-word
+              Control-o: "> output"
+
+       In the above example, _C_-_u is bound to the function uunniivveerr--
+       ssaall--aarrgguummeenntt,   _M_-_D_E_L  is  bound  to  the  function  bbaacckk--
+       wwaarrdd--kkiillll--wwoorrdd,  and  _C_-_o  is  bound  to  run  the   macro
+       expressed  on  the right hand side (that is, to insert the
+       text ``> output'' into the line).
+
+       In the second form, ""kkeeyysseeqq"":_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o,  kkeeyy--
+       sseeqq differs from kkeeyynnaammee above in that strings denoting an
+       entire key  sequence  may  be  specified  by  placing  the
+       sequence  within  double quotes.  Some GNU Emacs style key
+       escapes can be used, as in the following example, but  the
+       symbolic character names are not recognized.
+
+              "\C-u": universal-argument
+              "\C-x\C-r": re-read-init-file
+              "\e[11~": "Function Key 1"
+
+       In  this  example, _C_-_u is again bound to the function uunnii--
+       vveerrssaall--aarrgguummeenntt.   _C_-_x  _C_-_r  is  bound  to  the   function
+       rree--rreeaadd--iinniitt--ffiillee,  and _E_S_C _[ _1 _1 _~ is bound to insert the
+       text ``Function Key 1''.
+
+       The full set of GNU Emacs style escape sequences available
+       when specifying key sequences is
+              \\CC--    control prefix
+              \\MM--    meta prefix
+              \\ee     an escape character
+              \\\\     backslash
+              \\""     literal ", a double quote
+              \\''     literal ', a single quote
+
+       In  addition  to  the  GNU Emacs style escape sequences, a
+       second set of backslash escapes is available:
+              \\aa     alert (bell)
+              \\bb     backspace
+              \\dd     delete
+              \\ff     form feed
+              \\nn     newline
+              \\rr     carriage return
+              \\tt     horizontal tab
+              \\vv     vertical tab
+              \\_n_n_n   the eight-bit character whose value  is  the
+                     octal value _n_n_n (one to three digits)
+              \\xx_H_H   the  eight-bit  character whose value is the
+                     hexadecimal value _H_H (one or two hex digits)
+
+       When entering the text of a macro, single or double quotes
+       should be used to indicate a macro  definition.   Unquoted
+       text is assumed to be a function name.  In the macro body,
+       the backslash escapes described above are expanded.  Back-
+       slash  will  quote  any other character in the macro text,
+       including " and '.
+
+       BBaasshh allows the current readline key bindings to  be  dis-
+       played  or  modified  with  the bbiinndd builtin command.  The
+       editing mode may be switched  during  interactive  use  by
+       using  the  --oo  option  to the sseett builtin command.  Other
+       programs using this library  provide  similar  mechanisms.
+       The  _i_n_p_u_t_r_c  file  may be edited and re-read if a program
+       does not provide any other means to incorporate new  bind-
+       ings.
+
+   VVaarriiaabblleess
+       Readline  has  variables  that can be used to further cus-
+       tomize its behavior.  A variable may be set in the _i_n_p_u_t_r_c
+       file with a statement of the form
+
+              sseett _v_a_r_i_a_b_l_e_-_n_a_m_e _v_a_l_u_e
+
+       Except where noted, readline variables can take the values
+       OOnn or OOffff (without regard to  case).   The  variables  and
+       their default values are:
+
+       bbeellll--ssttyyllee ((aauuddiibbllee))
+              Controls  what  happens when readline wants to ring
+              the terminal bell.  If set to nnoonnee, readline  never
+              rings the bell.  If set to vviissiibbllee, readline uses a
+              visible bell if one is available.  If set to  aauuddii--
+              bbllee, readline attempts to ring the terminal's bell.
+       ccoommmmeenntt--bbeeggiinn ((````##''''))
+              The string that is inserted in  vvii  mode  when  the
+              iinnsseerrtt--ccoommmmeenntt  command  is executed.  This command
+              is bound to MM--## in emacs mode and to ## in  vi  com-
+              mand mode.
+       ccoommpplleettiioonn--iiggnnoorree--ccaassee ((OOffff))
+              If  set  to OOnn, readline performs filename matching
+              and completion in a case-insensitive fashion.
+       ccoommpplleettiioonn--qquueerryy--iitteemmss ((110000))
+              This determines when  the  user  is  queried  about
+              viewing  the  number of possible completions gener-
+              ated by the ppoossssiibbllee--ccoommpplleettiioonnss command.   It  may
+              be  set  to any integer value greater than or equal
+              to zero.  If the number of possible completions  is
+              greater  than  or  equal to the value of this vari-
+              able, the user is asked whether or not he wishes to
+              view  them; otherwise they are simply listed on the
+              terminal.
+       ccoonnvveerrtt--mmeettaa ((OOnn))
+              If set to OOnn, readline will convert characters with
+              the  eighth  bit  set  to  an ASCII key sequence by
+              stripping the eighth bit and prefixing it  with  an
+              escape  character  (in  effect, using escape as the
+              _m_e_t_a _p_r_e_f_i_x).
+       ddiissaabbllee--ccoommpplleettiioonn ((OOffff))
+              If set to OOnn, readline will  inhibit  word  comple-
+              tion.   Completion characters will be inserted into
+              the line as if they had been mapped to sseellff--iinnsseerrtt.
+       eeddiittiinngg--mmooddee ((eemmaaccss))
+              Controls  whether readline begins with a set of key
+              bindings similar to emacs or vi.  eeddiittiinngg--mmooddee  can
+              be set to either eemmaaccss or vvii.
+       eennaabbllee--kkeeyyppaadd ((OOffff))
+              When  set  to  OOnn,  readline will try to enable the
+              application keypad when it is called.  Some systems
+              need this to enable the arrow keys.
+       eexxppaanndd--ttiillddee ((OOffff))
+              If  set  to  oonn,  tilde expansion is performed when
+              readline attempts word completion.
+       hhiissttoorryy--pprreesseerrvvee--ppooiinntt
+              If set to oonn, the history code  attempts  to  place
+              point  at  the  same  location on each history line
+              retrived with pprreevviioouuss--hhiissttoorryy or nneexxtt--hhiissttoorryy.
+       hhoorriizzoonnttaall--ssccrroollll--mmooddee ((OOffff))
+              When set to OOnn, makes readline use  a  single  line
+              for  display, scrolling the input horizontally on a
+              single screen line when it becomes longer than  the
+              screen width rather than wrapping to a new line.
+       iinnppuutt--mmeettaa ((OOffff))
+              If  set to OOnn, readline will enable eight-bit input
+              (that is, it will not clear the eighth bit  in  the
+              characters it reads), regardless of what the termi-
+              nal claims it can support.  The name mmeettaa--ffllaagg is a
+              synonym for this variable.
+       iisseeaarrcchh--tteerrmmiinnaattoorrss ((````CC--[[ CC--JJ''''))
+              The  string  of characters that should terminate an
+              incremental search without  subsequently  executing
+              the  character  as a command.  If this variable has
+              not been given a value, the characters _E_S_C and  _C_-_J
+              will terminate an incremental search.
+       kkeeyymmaapp ((eemmaaccss))
+              Set  the current readline keymap.  The set of legal
+              keymap names is _e_m_a_c_s_, _e_m_a_c_s_-_s_t_a_n_d_a_r_d_,  _e_m_a_c_s_-_m_e_t_a_,
+              _e_m_a_c_s_-_c_t_l_x_, _v_i_, _v_i_-_m_o_v_e_, _v_i_-_c_o_m_m_a_n_d, and _v_i_-_i_n_s_e_r_t.
+              _v_i is equivalent to _v_i_-_c_o_m_m_a_n_d; _e_m_a_c_s is equivalent
+              to  _e_m_a_c_s_-_s_t_a_n_d_a_r_d.   The  default  value is _e_m_a_c_s.
+              The value of eeddiittiinngg--mmooddee also affects the  default
+              keymap.
+       mmaarrkk--ddiirreeccttoorriieess ((OOnn))
+              If  set  to  OOnn,  completed  directory names have a
+              slash appended.
+       mmaarrkk--mmooddiiffiieedd--lliinneess ((OOffff))
+              If set to OOnn, history lines that have been modified
+              are displayed with a preceding asterisk (**).
+       mmaarrkk--ssyymmlliinnkkeedd--ddiirreeccttoorriieess ((OOffff))
+              If  set  to  OOnn, completed names which are symbolic
+              links to directories have a slash appended (subject
+              to the value of mmaarrkk--ddiirreeccttoorriieess).
+       mmaattcchh--hhiiddddeenn--ffiilleess ((OOnn))
+              This  variable,  when set to OOnn, causes readline to
+              match files whose names begin with  a  `.'  (hidden
+              files)  when performing filename completion, unless
+              the leading `.' is supplied  by  the  user  in  the
+              filename to be completed.
+       oouuttppuutt--mmeettaa ((OOffff))
+              If set to OOnn, readline will display characters with
+              the eighth bit set directly rather than as a  meta-
+              prefixed escape sequence.
+       ppaaggee--ccoommpplleettiioonnss ((OOnn))
+              If  set  to OOnn, readline uses an internal _m_o_r_e-like
+              pager to display a screenful  of  possible  comple-
+              tions at a time.
+       pprriinntt--ccoommpplleettiioonnss--hhoorriizzoonnttaallllyy ((OOffff))
+              If  set  to  OOnn,  readline will display completions
+              with matches sorted  horizontally  in  alphabetical
+              order, rather than down the screen.
+       sshhooww--aallll--iiff--aammbbiigguuoouuss ((OOffff))
+              This  alters the default behavior of the completion
+              functions.  If set to oonn,  words  which  have  more
+              than  one  possible completion cause the matches to
+              be listed immediately instead of ringing the  bell.
+       vviissiibbllee--ssttaattss ((OOffff))
+              If set to OOnn, a character denoting a file's type as
+              reported by _s_t_a_t(2) is  appended  to  the  filename
+              when listing possible completions.
+
+   CCoonnddiittiioonnaall CCoonnssttrruuccttss
+       Readline  implements  a  facility similar in spirit to the
+       conditional compilation features  of  the  C  preprocessor
+       which allows key bindings and variable settings to be per-
+       formed as the result of  tests.   There  are  four  parser
+       directives used.
+
+       $$iiff    The  $$iiff construct allows bindings to be made based
+              on the editing mode, the terminal  being  used,  or
+              the  application  using  readline.  The text of the
+              test extends to the end of the line; no  characters
+              are required to isolate it.
+
+              mmooddee   The  mmooddee== form of the $$iiff directive is used
+                     to test whether readline is in emacs  or  vi
+                     mode.   This may be used in conjunction with
+                     the sseett kkeeyymmaapp command, for instance, to set
+                     bindings  in  the  _e_m_a_c_s_-_s_t_a_n_d_a_r_d and _e_m_a_c_s_-
+                     _c_t_l_x keymaps only if  readline  is  starting
+                     out in emacs mode.
+
+              tteerrmm   The tteerrmm== form may be used to include termi-
+                     nal-specific key bindings, perhaps  to  bind
+                     the  key  sequences output by the terminal's
+                     function keys.  The word on the  right  side
+                     of  the == is tested against the full name of
+                     the terminal and the portion of the terminal
+                     name before the first --.  This allows _s_u_n to
+                     match both _s_u_n and _s_u_n_-_c_m_d, for instance.
+
+              aapppplliiccaattiioonn
+                     The aapppplliiccaattiioonn construct is used to include
+                     application-specific settings.  Each program
+                     using the readline library sets the _a_p_p_l_i_c_a_-
+                     _t_i_o_n  _n_a_m_e,  and  an initialization file can
+                     test for a particular value.  This could  be
+                     used to bind key sequences to functions use-
+                     ful for a specific program.   For  instance,
+                     the  following  command  adds a key sequence
+                     that quotes the current or previous word  in
+                     Bash:
+
+                     $$iiff Bash
+                     # Quote the current or previous word
+                     "\C-xq": "\eb\"\ef\""
+                     $$eennddiiff
+
+       $$eennddiiff This command, as seen in the previous example, ter-
+              minates an $$iiff command.
+
+       $$eellssee  Commands in this branch of the  $$iiff  directive  are
+              executed if the test fails.
+
+       $$iinncclluuddee
+              This  directive takes a single filename as an argu-
+              ment and reads  commands  and  bindings  from  that
+              file.   For  example, the following directive would
+              read _/_e_t_c_/_i_n_p_u_t_r_c:
+
+              $$iinncclluuddee  _/_e_t_c_/_i_n_p_u_t_r_c
+
+SSEEAARRCCHHIINNGG
+       Readline provides commands for searching through the  com-
+       mand  history  for  lines  containing  a specified string.
+       There are two search modes: _i_n_c_r_e_m_e_n_t_a_l and  _n_o_n_-_i_n_c_r_e_m_e_n_-
+       _t_a_l.
+
+       Incremental  searches  begin  before the user has finished
+       typing the search string.  As each character of the search
+       string is typed, readline displays the next entry from the
+       history matching the string typed so far.  An  incremental
+       search  requires only as many characters as needed to find
+       the desired history entry.  To search backward in the his-
+       tory  for  a  particular  string,  type  CC--rr.   Typing CC--ss
+       searches forward through the history.  The characters pre-
+       sent  in the value of the iisseeaarrcchh--tteerrmmiinnaattoorrss variable are
+       used to terminate an incremental search.  If that variable
+       has  not  been assigned a value the _E_s_c_a_p_e and CC--JJ charac-
+       ters will terminate an incremental search.  CC--GG will abort
+       an incremental search and restore the original line.  When
+       the search is terminated, the history entry containing the
+       search string becomes the current line.
+
+       To  find  other matching entries in the history list, type
+       CC--ss or CC--rr as appropriate.  This will search  backward  or
+       forward  in  the  history  for  the next line matching the
+       search string typed so far.  Any other key sequence  bound
+       to  a  readline command will terminate the search and exe-
+       cute that command.  For instance, a newline will terminate
+       the search and accept the line, thereby executing the com-
+       mand from the history list.  A movement command will  ter-
+       minate  the  search,  make the last line found the current
+       line, and begin editing.
+
+       Non-incremental searches read  the  entire  search  string
+       before starting to search for matching history lines.  The
+       search string may be typed by the user or be part  of  the
+       contents of the current line.
+

+       The  following  is a list of the names of the commands and

+       mand  names  without  an  accompanying  key  sequence  are
+       unbound by default.
+
+       In the following descriptions, _p_o_i_n_t refers to the current

+              tive argument.
+       uunniivveerrssaall--aarrgguummeenntt
+              This  is  another  way  to specify an argument.  If
+              this command is followed by  one  or  more  digits,
+              optionally  with a leading minus sign, those digits
+              define the argument.  If the command is followed by
+              digits, executing uunniivveerrssaall--aarrgguummeenntt again ends the
+              numeric argument, but is otherwise ignored.   As  a
+              special  case,  if this command is immediately fol-
+              lowed by a character that is  neither  a  digit  or
+              minus sign, the argument count for the next command
+              is multiplied by four.  The argument count is  ini-
+              tially  one,  so  executing this function the first
+              time makes the argument count four, a  second  time
+              makes the argument count sixteen, and so on.

+              If none of these produces a match, filename comple-

+       The following is a list of the default emacs and vi  bind-
+       ings.   Characters  with the eighth bit set are written as
+       M-<character>, and are referred to as _m_e_t_a_f_i_e_d characters.
+       The  printable  ASCII characters not mentioned in the list
+       of emacs standard bindings are bound  to  the  sseellff--iinnsseerrtt
+       function,  which just inserts the given character into the
+       input line.  In vi  insertion  mode,  all  characters  not
+       specifically  mentioned are bound to sseellff--iinnsseerrtt.  Charac-
+       ters assigned to signal generation by _s_t_t_y(1) or the  ter-
+       minal  driver,  such  as C-Z or C-C, retain that function.
+       Upper and lower case metafied characters are bound to  the
+       same  function in the emacs mode meta keymap.  The remain-
+       ing characters are unbound, which causes readline to  ring
+       the  bell  (subject to the setting of the bbeellll--ssttyyllee vari-
+       able).

+</P><P>
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+</P><P>
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</P><P>
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+<EM>first</EM>, and then typing <KBD>k</KBD>.
+Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
+</P><P>

+
+In addition, several keys have their own names.  Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all

+<!--docid::SEC3::-->
+<P>
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</P><P>
+
+Readline remembers the last incremental search string.  If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+<P>
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+There are only a few basic constructs allowed in the
+Readline init file.  Blank lines are ignored.
+Lines beginning with a <SAMP>`#'</SAMP> are comments.
+Lines beginning with a <SAMP>`$'</SAMP> indicate conditional
+constructs (see section <A HREF="readline.html#SEC11">1.3.2 Conditional Init Constructs</A>).  Other lines
+denote variable settings and key bindings.
+</P><P>
+
+<DL COMPACT>
+<DT>Variable Settings
+<DD>You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the <CODE>set</CODE> command within the init file.
+The syntax is simple:
+<P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set <VAR>variable</VAR> <VAR>value</VAR>
+</pre></td></tr></table></P><P>
+
+Here, for example, is how to

+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set editing-mode vi
+</pre></td></tr></table></P><P>
+
+Variable names and values, where appropriate, are recognized without regard
+to case. 
+</P><P>
+
+A great deal of run-time behavior is changeable with the following
+variables.
+</P><P>
+
+<A NAME="IDX4"></A>
+<DL COMPACT>
+
+<DT><CODE>bell-style</CODE>
+<DD><A NAME="IDX5"></A>
+Controls what happens when Readline wants to ring the terminal bell.
+If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
+<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
+If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
+the terminal's bell.
+<P>
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX6"></A>
+The string to insert at the beginning of the line when the
+<CODE>insert-comment</CODE> command is executed.  The default value
+is <CODE>"#"</CODE>.
+<P>
+
+<DT><CODE>completion-ignore-case</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX7"></A>
+The number of possible completions that determines when the user is
+asked whether he wants to see the list of possibilities.  If the
+number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>disable-completion</CODE>
+<DD><A NAME="IDX9"></A>
+If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>editing-mode</CODE>
+<DD><A NAME="IDX10"></A>
+The <CODE>editing-mode</CODE> variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+<P>
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX11"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>expand-tilde</CODE>
+<DD><A NAME="IDX12"></A>
+If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
+attempts word completion.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, the history code attempts to place point at the
+same location on each history line retrived with <CODE>previous-history</CODE>
+or <CODE>next-history</CODE>.
+</P><P>
+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX14"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,
+this variable is set to <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>input-meta</CODE>
+<DD><A NAME="IDX15"></A>
+<A NAME="IDX16"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
+synonym for this variable.
+<P>
+
+<DT><CODE>isearch-terminators</CODE>
+<DD><A NAME="IDX17"></A>
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (see section <A HREF="readline.html#SEC8">1.2.5 Searching for Commands in the History</A>).
+If this variable has not been given a value, the characters <KBD>ESC</KBD> and
+<KBD>C-J</KBD> will terminate an incremental search.
+<P>
+
+<DT><CODE>keymap</CODE>
+<DD><A NAME="IDX18"></A>
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable <CODE>keymap</CODE> names are
+<CODE>emacs</CODE>,
+<CODE>emacs-standard</CODE>,
+<CODE>emacs-meta</CODE>,
+<CODE>emacs-ctlx</CODE>,
+<CODE>vi</CODE>,
+<CODE>vi-move</CODE>,
+<CODE>vi-command</CODE>, and
+<CODE>vi-insert</CODE>.
+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
+equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the
+default keymap.
+<P>
+
+<DT><CODE>mark-directories</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
+appended.  The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>mark-modified-lines</CODE>
+<DD><A NAME="IDX19"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
+asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
+This variable is <SAMP>`off'</SAMP> by default.
+<P>
+
+<DT><CODE>mark-symlinked-directories</CODE>
+<DD><A NAME="IDX20"></A>
+If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+<CODE>mark-directories</CODE>).
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX21"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
+names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
+completion, unless the leading <SAMP>`.'</SAMP> is
+supplied by the user in the filename to be completed.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX22"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX23"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
+to display a screenful of possible completions at a time.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>print-completions-horizontally</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>show-all-if-ambiguous</CODE>
+<DD><A NAME="IDX24"></A>
+This alters the default behavior of the completion functions.  If
+set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>visible-stats</CODE>
+<DD><A NAME="IDX25"></A>
+If set to <SAMP>`on'</SAMP>, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+</DL>
+<P>
+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+<P>
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.  The name of the key
+can be expressed in different ways, depending on what you find most
+comfortable.
+</P><P>
+
+In addition to command names, readline allows keys to be bound

+</P><P>
+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyname</VAR> is the name of a key spelled out in English.  For example:

+Meta-Rubout: backward-kill-word
+Control-o: "&#62; output"
+</pre></td></tr></table><P>

+In the above example, <KBD>C-u</KBD> is bound to the function
+<CODE>universal-argument</CODE>,
+<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
+<KBD>C-o</KBD> is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<SAMP>`&#62; output'</SAMP> into the line).

+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+</P><P>
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+<P>
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+<P>
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc

+<H2> 2.1 Basic Behavior </H2>
+<!--docid::SEC24::-->
+<P>
+
+Many programs provide a command line interface, such as <CODE>mail</CODE>,
+<CODE>ftp</CODE>, and <CODE>sh</CODE>.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+<CODE>gets()</CODE> or <CODE>fgets()</CODE>.
+</P><P>
+
+<A NAME="IDX174"></A>
+<A NAME="IDX175"></A>
+</P><P>
+
+The function <CODE>readline()</CODE> prints a prompt <VAR>prompt</VAR>
+and then reads and returns a single line of text from the user.
+If <VAR>prompt</VAR> is <CODE>NULL</CODE> or the empty string, no prompt is displayed.
+The line <CODE>readline</CODE> returns is allocated with <CODE>malloc()</CODE>;
+the caller should <CODE>free()</CODE> the line when it has finished with it.
+The declaration for <CODE>readline</CODE> in ANSI C is
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *readline (const char *<VAR>prompt</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+So, one might say
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *line = readline ("Enter a line: ");</CODE>
+</pre></td></tr></table>in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+</P><P>
+
+If <CODE>readline</CODE> encounters an <CODE>EOF</CODE> while reading the line, and the
+line is empty at that point, then <CODE>(char *)NULL</CODE> is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+</P><P>
+
+If you want the user to be able to get at the line later, (with
+<KBD>C-p</KBD> for example), you must call <CODE>add_history()</CODE> to save the
+line away in a <EM>history</EM> list of such lines.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>add_history (line)</CODE>;
+</pre></td></tr></table></P><P>
+
+For full details on the GNU History Library, see the associated manual.
+</P><P>
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard <CODE>gets()</CODE> library
+function, and has the advantage of no static buffer to overflow:
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    {
+      free (line_read);
+      line_read = (char *)NULL;
+    }
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read &#38;&#38; *line_read)
+    add_history (line_read);
+
+  return (line_read);
+}
+</pre></td></tr></table></P><P>
+
+This function gives the user the default behaviour of <KBD>TAB</KBD>
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the <KBD>TAB</KBD> key
+with <CODE>rl_bind_key()</CODE>.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int rl_bind_key (int <VAR>key</VAR>, rl_command_func_t *<VAR>function</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+<CODE>rl_bind_key()</CODE> takes two arguments: <VAR>key</VAR> is the character that
+you want to bind, and <VAR>function</VAR> is the address of the function to
+call when <VAR>key</VAR> is pressed.  Binding <KBD>TAB</KBD> to <CODE>rl_insert()</CODE>
+makes <KBD>TAB</KBD> insert itself.
+<CODE>rl_bind_key()</CODE> returns non-zero if <VAR>key</VAR> is not a valid
+ASCII character code (between 0 and 255).
+</P><P>
+
+Thus, to disable the default <KBD>TAB</KBD> behavior, the following suffices:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>rl_bind_key ('\t', rl_insert);</CODE>
+</pre></td></tr></table></P><P>
+
+This code should be executed once at the start of your program; you
+might write a function called <CODE>initialize_readline()</CODE> which
+performs this and other desired initializations, such as installing
+custom completers (see section <A HREF="readline.html#SEC44">2.6 Custom Completers</A>).

+<H2> 2.2 Custom Functions </H2>
+<!--docid::SEC25::-->
+<P>
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+</P><P>
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file <CODE>&#60;readline/readline.h&#62;</CODE>
+in any file that uses Readline's features.  Since some of the definitions
+in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
+<CODE>&#60;stdio.h&#62;</CODE> should be included before <CODE>readline.h</CODE>.
+</P><P>
+
+<CODE>readline.h</CODE> defines a C preprocessor variable that should
+be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x<VAR>MMmm</VAR>.  <VAR>MM</VAR> is the two-digit major
+version number; <VAR>mm</VAR> is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+<CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+</P><P>
+
+The calling sequence for a command <CODE>foo</CODE> looks like

+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int foo (int count, int key)</CODE>

+where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
+<VAR>key</VAR> is the key that invoked this function.
+</P><P>
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.

+
+The user can dynamically change the bindings of keys while using

+name.  The user is able to type the descriptive name when referring to

+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Meta-Rubout:	backward-kill-word

+
+This binds the keystroke <KBD>Meta-Rubout</KBD> to the function
+<EM>descriptively</EM> named <CODE>backward-kill-word</CODE>.  You, as the
+programmer, should bind the functions you write to descriptive names as

+<VAR>function</VAR> using <CODE>rl_bind_key()</CODE>.
+</DL>
+</P><P>
+
+Using this function alone is sufficient for most applications.  It is
+the recommended way to add a few functions to the default functions that
+Readline has built in.  If you need to do something other

+<!--docid::SEC34::-->

+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try
+something if you know you can undo it.
+</P><P>
+
+If your function simply inserts text once, or deletes text once, and
+uses <CODE>rl_insert_text()</CODE> or <CODE>rl_delete_text()</CODE> to do it, then
+undoing is already done for you automatically.
+</P><P>
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with <CODE>rl_begin_undo_group()</CODE> and
+<CODE>rl_end_undo_group()</CODE>.
+</P><P>

+
+Notice that <CODE>UNDO_DELETE</CODE> means to insert some text, and
+<CODE>UNDO_INSERT</CODE> means to delete some text.  That is, the undo code
+tells what to undo, not how to undo it.  <CODE>UNDO_BEGIN</CODE> and

+<H2> 2.5 Readline Signal Handling </H2>
+<!--docid::SEC43::-->
+<P>
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+</P><P>
+
+Readline contains an internal signal handler that is installed for a
+number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
+<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+<CODE>readline()</CODE> was called, reset the signal handling to what it was
+before <CODE>readline()</CODE> was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
+</P><P>
+
+There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an <CODE>xterm</CODE>).  The Readline <CODE>SIGWINCH</CODE>
+handler updates Readline's internal screen size information, and then calls
+any <CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
+Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
+call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
+terminal state. 
+</P><P>
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling <CODE>readline()</CODE>, not in
+a signal handler, so Readline's internal signal state is not corrupted.

+<H3> 2.6.1 How Completing Works </H3>
+<!--docid::SEC45::-->
+<P>
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+</P><P>
+
+There are three major functions used to perform completion:
+</P><P>
+
+<OL>
+<LI>
+The user-interface function <CODE>rl_complete()</CODE>.  This function is
+called with the same arguments as other bindable Readline functions:
+<VAR>count</VAR> and <VAR>invoking_key</VAR>.
+It isolates the word to be completed and calls
+<CODE>rl_completion_matches()</CODE> to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+<P>
+
+<LI>
+The internal function <CODE>rl_completion_matches()</CODE> uses an
+application-supplied <EM>generator</EM> function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+<CODE>rl_completion_entry_function</CODE>.
+<P>
+
+<LI>
+The generator function is called repeatedly from
+<CODE>rl_completion_matches()</CODE>, returning a string each time.  The
+arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
+<VAR>text</VAR> is the partial word to be completed.  <VAR>state</VAR> is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+<CODE>(char *)NULL</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when <VAR>state</VAR> is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
+frees the strings when it has finished with them.

+Introduction to Line Editing
+============================
+
+   The following paragraphs describe the notation used to represent
+keystrokes.
+
+   The text `C-k' is read as `Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+   The text `M-k' is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key.  The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+   If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>.  Either process is known as "metafying"
+the <k> key.
+
+   The text `M-C-k' is read as `Meta-Control-k' and describes the
+character produced by "metafying" `C-k'.
+
+   In addition, several keys have their own names.  Specifically,
+<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
+when seen in this text, or in an init file (*note Readline Init File::).
+If your keyboard lacks a <LFD> key, typing <C-j> will produce the
+desired character.  The <RET> key may be labeled <Return> or <Enter> on
+some keyboards.

+
+Readline Interaction
+====================
+
+   Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <RET>.  You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.
+

+
+Readline Bare Essentials
+------------------------
+
+   In order to enter characters into the line, simply type them.  The
+typed character appears where the cursor was, and then the cursor moves
+one space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+   Sometimes you may mistype a character, and not notice the error
+until you have typed several other characters.  In that case, you can
+type `C-b' to move the cursor to the left, and then correct your
+mistake.  Afterwards, you can move the cursor to the right with `C-f'.
+
+   When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are `pushed over' to make room
+for the text that you have inserted.  Likewise, when you delete text
+behind the cursor, characters to the right of the cursor are `pulled
+back' to fill in the blank space created by the removal of the text.  A
+list of the bare essentials for editing the text of an input line
+follows.
+
+`C-b'
+     Move back one character.
+
+`C-f'
+     Move forward one character.
+
+<DEL> or <Backspace>
+     Delete the character to the left of the cursor.
+
+`C-d'
+     Delete the character underneath the cursor.
+
+Printing characters
+     Insert the character into the line at the cursor.
+
+`C-_' or `C-x C-u'
+     Undo the last editing command.  You can undo all the way back to an
+     empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like `C-d', rather than the
+character to the left of the cursor.)

+
+Readline Movement Commands
+--------------------------
+
+   The above table describes the most basic keystrokes that you need in
+order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to `C-b', `C-f', `C-d', and
+<DEL>.  Here are some commands for moving more rapidly about the line.
+
+`C-a'
+     Move to the start of the line.
+
+`C-e'
+     Move to the end of the line.
+
+`M-f'
+     Move forward a word, where a word is composed of letters and
+     digits.
+
+`M-b'
+     Move backward a word.
+
+`C-l'
+     Clear the screen, reprinting the current line at the top.
+
+   Notice how `C-f' moves forward a character, while `M-f' moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.

+
+Readline Killing Commands
+-------------------------
+
+   "Killing" text means to delete the text from the line, but to save
+it away for later use, usually by "yanking" (re-inserting) it back into
+the line.  (`Cut' and `paste' are more recent jargon for `kill' and
+`yank'.)
+
+   If the description for a command says that it `kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+   When you use a kill command, the text is saved in a "kill-ring".
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+   Here is the list of commands for killing text.
+
+`C-k'
+     Kill the text from the current cursor position to the end of the
+     line.
+
+`M-d'
+     Kill from the cursor to the end of the current word, or, if between
+     words, to the end of the next word.  Word boundaries are the same
+     as those used by `M-f'.
+
+`M-<DEL>'
+     Kill from the cursor the start of the current word, or, if between
+     words, to the start of the previous word.  Word boundaries are the
+     same as those used by `M-b'.
+
+`C-w'
+     Kill from the cursor to the previous whitespace.  This is
+     different than `M-<DEL>' because the word boundaries differ.
+
+   Here is how to "yank" the text back into the line.  Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+`C-y'
+     Yank the most recently killed text back into the buffer at the
+     cursor.
+
+`M-y'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `C-y' or `M-y'.
+
+
+File: readline.info,  Node: Readline Arguments,  Next: Searching,  Prev: Readline Killing Commands,  Up: Readline Interaction
+
+Readline Arguments
+------------------
+
+   You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type `M-- C-k'.
+
+   The general way to pass numeric arguments to a command is to type
+meta digits before the command.  If the first `digit' typed is a minus
+sign (`-'), then the sign of the argument will be negative.  Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command.  For example, to give
+the `C-d' command an argument of 10, you could type `M-1 0 C-d', which
+will delete the next ten characters on the input line.
+
+
+File: readline.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
+
+Searching for Commands in the History
+-------------------------------------
+
+   Readline provides commands for searching through the command history
+for lines containing a specified string.  There are two search modes:
+"incremental" and "non-incremental".
+
+   Incremental searches begin before the user has finished typing the
+search string.  As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far.  An incremental search requires only as many characters
+as needed to find the desired history entry.  To search backward in the
+history for a particular string, type `C-r'.  Typing `C-s' searches
+forward through the history.  The characters present in the value of
+the `isearch-terminators' variable are used to terminate an incremental
+search.  If that variable has not been assigned a value, the <ESC> and
+`C-J' characters will terminate an incremental search.  `C-g' will
+abort an incremental search and restore the original line.  When the
+search is terminated, the history entry containing the search string
+becomes the current line.
+
+   To find other matching entries in the history list, type `C-r' or
+`C-s' as appropriate.  This will search backward or forward in the
+history for the next entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate the
+search and execute that command.  For instance, a <RET> will terminate
+the search and accept the line, thereby executing the command from the
+history list.  A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+   Readline remembers the last incremental search string.  If two
+`C-r's are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+   Non-incremental searches read the entire search string before
+starting to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+Readline Init File
+==================
+
+   Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.  Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory.  The name of this file is taken from the value of the
+environment variable `INPUTRC'.  If that variable is unset, the default
+is `~/.inputrc'.
+
+   When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+   In addition, the `C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+
+* Menu:
+
+* Readline Init File Syntax::	Syntax for the commands in the inputrc file.
+
+* Conditional Init Constructs::	Conditional key bindings in the inputrc file.
+
+* Sample Init File::		An example inputrc file.
+
+
+File: readline.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
+
+Readline Init File Syntax
+-------------------------
+
+   There are only a few basic constructs allowed in the Readline init
+file.  Blank lines are ignored.  Lines beginning with a `#' are
+comments.  Lines beginning with a `$' indicate conditional constructs
+(*note Conditional Init Constructs::).  Other lines denote variable
+settings and key bindings.
+
+Variable Settings
+     You can modify the run-time behavior of Readline by altering the
+     values of variables in Readline using the `set' command within the
+     init file.  The syntax is simple:
+
+          set VARIABLE VALUE
+
+     Here, for example, is how to change from the default Emacs-like
+     key binding to use `vi' line editing commands:
+
+          set editing-mode vi
+
+     Variable names and values, where appropriate, are recognized
+     without regard to case.
+
+     A great deal of run-time behavior is changeable with the following
+     variables.
+
+    `bell-style'
+          Controls what happens when Readline wants to ring the
+          terminal bell.  If set to `none', Readline never rings the
+          bell.  If set to `visible', Readline uses a visible bell if
+          one is available.  If set to `audible' (the default),
+          Readline attempts to ring the terminal's bell.
+
+    `comment-begin'
+          The string to insert at the beginning of the line when the
+          `insert-comment' command is executed.  The default value is
+          `"#"'.
+
+    `completion-ignore-case'
+          If set to `on', Readline performs filename matching and
+          completion in a case-insensitive fashion.  The default value
+          is `off'.
+
+    `completion-query-items'
+          The number of possible completions that determines when the
+          user is asked whether he wants to see the list of
+          possibilities.  If the number of possible completions is
+          greater than this value, Readline will ask the user whether
+          or not he wishes to view them; otherwise, they are simply
+          listed.  This variable must be set to an integer value
+          greater than or equal to 0.  The default limit is `100'.
+
+    `convert-meta'
+          If set to `on', Readline will convert characters with the
+          eighth bit set to an ASCII key sequence by stripping the
+          eighth bit and prefixing an <ESC> character, converting them
+          to a meta-prefixed key sequence.  The default value is `on'.
+
+    `disable-completion'
+          If set to `On', Readline will inhibit word completion.
+          Completion  characters will be inserted into the line as if
+          they had been mapped to `self-insert'.  The default is `off'.
+
+    `editing-mode'
+          The `editing-mode' variable controls which default set of key
+          bindings is used.  By default, Readline starts up in Emacs
+          editing mode, where the keystrokes are most similar to Emacs.
+          This variable can be set to either `emacs' or `vi'.
+
+    `enable-keypad'
+          When set to `on', Readline will try to enable the application
+          keypad when it is called.  Some systems need this to enable
+          the arrow keys.  The default is `off'.
+
+    `expand-tilde'
+          If set to `on', tilde expansion is performed when Readline
+          attempts word completion.  The default is `off'.
+
+          If set to `on', the history code attempts to place point at
+          the same location on each history line retrived with
+          `previous-history' or `next-history'.
+
+    `horizontal-scroll-mode'
+          This variable can be set to either `on' or `off'.  Setting it
+          to `on' means that the text of the lines being edited will
+          scroll horizontally on a single screen line when they are
+          longer than the width of the screen, instead of wrapping onto
+          a new screen line.  By default, this variable is set to `off'.
+
+    `input-meta'
+          If set to `on', Readline will enable eight-bit input (it will
+          not clear the eighth bit in the characters it reads),
+          regardless of what the terminal claims it can support.  The
+          default value is `off'.  The name `meta-flag' is a synonym
+          for this variable.
+
+    `isearch-terminators'
+          The string of characters that should terminate an incremental
+          search without subsequently executing the character as a
+          command (*note Searching::).  If this variable has not been
+          given a value, the characters <ESC> and `C-J' will terminate
+          an incremental search.
+
+    `keymap'
+          Sets Readline's idea of the current keymap for key binding
+          commands.  Acceptable `keymap' names are `emacs',
+          `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move',
+          `vi-command', and `vi-insert'.  `vi' is equivalent to
+          `vi-command'; `emacs' is equivalent to `emacs-standard'.  The
+          default value is `emacs'.  The value of the `editing-mode'
+          variable also affects the default keymap.
+
+    `mark-directories'
+          If set to `on', completed directory names have a slash
+          appended.  The default is `on'.
+
+    `mark-modified-lines'
+          This variable, when set to `on', causes Readline to display an
+          asterisk (`*') at the start of history lines which have been
+          modified.  This variable is `off' by default.
+
+    `mark-symlinked-directories'
+          If set to `on', completed names which are symbolic links to
+          directories have a slash appended (subject to the value of
+          `mark-directories').  The default is `off'.
+
+    `match-hidden-files'
+          This variable, when set to `on', causes Readline to match
+          files whose names begin with a `.' (hidden files) when
+          performing filename completion, unless the leading `.' is
+          supplied by the user in the filename to be completed.  This
+          variable is `on' by default.
+
+    `output-meta'
+          If set to `on', Readline will display characters with the
+          eighth bit set directly rather than as a meta-prefixed escape
+          sequence.  The default is `off'.
+
+    `page-completions'
+          If set to `on', Readline uses an internal `more'-like pager
+          to display a screenful of possible completions at a time.
+          This variable is `on' by default.
+
+    `print-completions-horizontally'
+          If set to `on', Readline will display completions with matches
+          sorted horizontally in alphabetical order, rather than down
+          the screen.  The default is `off'.
+
+    `show-all-if-ambiguous'
+          This alters the default behavior of the completion functions.
+          If set to `on', words which have more than one possible
+          completion cause the matches to be listed immediately instead
+          of ringing the bell.  The default value is `off'.
+
+    `visible-stats'
+          If set to `on', a character denoting a file's type is
+          appended to the filename when listing possible completions.
+          The default is `off'.
+
+Key Bindings
+     The syntax for controlling key bindings in the init file is
+     simple.  First you need to find the name of the command that you
+     want to change.  The following sections contain tables of the
+     command name, the default keybinding, if any, and a short
+     description of what the command does.
+
+     Once you know the name of the command, simply place on a line in
+     the init file the name of the key you wish to bind the command to,
+     a colon, and then the name of the command.  The name of the key
+     can be expressed in different ways, depending on what you find most
+     comfortable.
+
+     In addition to command names, readline allows keys to be bound to
+     a string that is inserted when the key is pressed (a MACRO).
+
+    KEYNAME: FUNCTION-NAME or MACRO
+          KEYNAME is the name of a key spelled out in English.  For
+          example:
+               Control-u: universal-argument
+               Meta-Rubout: backward-kill-word
+               Control-o: "> output"
+
+          In the above example, `C-u' is bound to the function
+          `universal-argument', `M-DEL' is bound to the function
+          `backward-kill-word', and `C-o' is bound to run the macro
+          expressed on the right hand side (that is, to insert the text
+          `> output' into the line).
+
+          A number of symbolic character names are recognized while
+          processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+          NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+    "KEYSEQ": FUNCTION-NAME or MACRO
+          KEYSEQ differs from KEYNAME above in that strings denoting an
+          entire key sequence can be specified, by placing the key
+          sequence in double quotes.  Some GNU Emacs style key escapes
+          can be used, as in the following example, but the special
+          character names are not recognized.
+
+               "\C-u": universal-argument
+               "\C-x\C-r": re-read-init-file
+               "\e[11~": "Function Key 1"
+
+          In the above example, `C-u' is again bound to the function
+          `universal-argument' (just as it was in the first example),
+          `C-x C-r' is bound to the function `re-read-init-file', and
+          `<ESC> <[> <1> <1> <~>' is bound to insert the text `Function
+          Key 1'.
+
+     The following GNU Emacs style escape sequences are available when
+     specifying key sequences:
+
+    `\C-'
+          control prefix
+
+    `\M-'
+          meta prefix
+
+    `\e'
+          an escape character
+
+    `\\'
+          backslash
+
+    `\"'
+          <">, a double quotation mark
+
+    `\''
+          <'>, a single quote or apostrophe
+
+     In addition to the GNU Emacs style escape sequences, a second set
+     of backslash escapes is available:
+
+    `\a'
+          alert (bell)
+
+    `\b'
+          backspace
+
+    `\d'
+          delete
+
+    `\f'
+          form feed
+
+    `\n'
+          newline
+
+    `\r'
+          carriage return
+
+    `\t'
+          horizontal tab
+
+    `\v'
+          vertical tab
+
+    `\NNN'
+          the eight-bit character whose value is the octal value NNN
+          (one to three digits)
+
+    `\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+
+     When entering the text of a macro, single or double quotes must be
+     used to indicate a macro definition.  Unquoted text is assumed to
+     be a function name.  In the macro body, the backslash escapes
+     described above are expanded.  Backslash will quote any other
+     character in the macro text, including `"' and `''.  For example,
+     the following binding will make `C-x \' insert a single `\' into
+     the line:
+          "\C-x\\": "\\"

+
+Conditional Init Constructs
+---------------------------
+
+   Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings
+and variable settings to be performed as the result of tests.  There
+are four parser directives used.
+
+`$if'
+     The `$if' construct allows bindings to be made based on the
+     editing mode, the terminal being used, or the application using
+     Readline.  The text of the test extends to the end of the line; no
+     characters are required to isolate it.
+
+    `mode'
+          The `mode=' form of the `$if' directive is used to test
+          whether Readline is in `emacs' or `vi' mode.  This may be
+          used in conjunction with the `set keymap' command, for
+          instance, to set bindings in the `emacs-standard' and
+          `emacs-ctlx' keymaps only if Readline is starting out in
+          `emacs' mode.
+
+    `term'
+          The `term=' form may be used to include terminal-specific key
+          bindings, perhaps to bind the key sequences output by the
+          terminal's function keys.  The word on the right side of the
+          `=' is tested against both the full name of the terminal and
+          the portion of the terminal name before the first `-'.  This
+          allows `sun' to match both `sun' and `sun-cmd', for instance.
+
+    `application'
+          The APPLICATION construct is used to include
+          application-specific settings.  Each program using the
+          Readline library sets the APPLICATION NAME, and you can test
+          for a particular value.  This could be used to bind key
+          sequences to functions useful for a specific program.  For
+          instance, the following command adds a key sequence that
+          quotes the current or previous word in Bash:
+               $if Bash
+               # Quote the current or previous word
+               "\C-xq": "\eb\"\ef\""
+               $endif
+
+`$endif'
+     This command, as seen in the previous example, terminates an `$if'
+     command.
+
+`$else'
+     Commands in this branch of the `$if' directive are executed if the
+     test fails.
+
+`$include'
+     This directive takes a single filename as an argument and reads
+     commands and bindings from that file.  For example, the following
+     directive reads from `/etc/inputrc':
+          $include /etc/inputrc
+

+
+Commands For Manipulating The History
+-------------------------------------
+
+`accept-line (Newline or Return)'
+     Accept the line regardless of where the cursor is.  If this line is
+     non-empty, it may be added to the history list for future recall
+     with `add_history()'.  If this line is a modified history line,
+     the history line is restored to its original state.
+
+`previous-history (C-p)'
+     Move `back' through the history list, fetching the previous
+     command.
+
+`next-history (C-n)'
+     Move `forward' through the history list, fetching the next command.
+
+`beginning-of-history (M-<)'
+     Move to the first line in the history.
+
+`end-of-history (M->)'
+     Move to the end of the input history, i.e., the line currently
+     being entered.
+
+`reverse-search-history (C-r)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary.  This is an incremental search.
+
+`forward-search-history (C-s)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary.  This is an incremental
+     search.
+
+`non-incremental-reverse-search-history (M-p)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`non-incremental-forward-search-history (M-n)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`history-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`history-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`yank-nth-arg (M-C-y)'
+     Insert the first argument to the previous command (usually the
+     second word on the previous line) at point.  With an argument N,
+     insert the Nth word from the previous command (the words in the
+     previous command begin with word 0).  A negative argument inserts
+     the Nth word from the end of the previous command.
+
+`yank-last-arg (M-. or M-_)'
+     Insert last argument to the previous command (the last word of the
+     previous history entry).  With an argument, behave exactly like
+     `yank-nth-arg'.  Successive calls to `yank-last-arg' move back
+     through the history list, inserting the last argument of each line
+     in turn.

+
+Commands For Changing Text
+--------------------------
+
+`delete-char (C-d)'
+     Delete the character at point.  If point is at the beginning of
+     the line, there are no characters in the line, and the last
+     character typed was not bound to `delete-char', then return EOF.
+
+`backward-delete-char (Rubout)'
+     Delete the character behind the cursor.  A numeric argument means
+     to kill the characters instead of deleting them.
+
+`forward-backward-delete-char ()'
+     Delete the character under the cursor, unless the cursor is at the
+     end of the line, in which case the character behind the cursor is
+     deleted.  By default, this is not bound to a key.
+
+`quoted-insert (C-q or C-v)'
+     Add the next character typed to the line verbatim.  This is how to
+     insert key sequences like `C-q', for example.
+
+`tab-insert (M-<TAB>)'
+     Insert a tab character.
+
+`self-insert (a, b, A, 1, !, ...)'
+     Insert yourself.
+
+`transpose-chars (C-t)'
+     Drag the character before the cursor forward over the character at
+     the cursor, moving the cursor forward as well.  If the insertion
+     point is at the end of the line, then this transposes the last two
+     characters of the line.  Negative arguments have no effect.
+
+`transpose-words (M-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.
+
+`upcase-word (M-u)'
+     Uppercase the current (or following) word.  With a negative
+     argument, uppercase the previous word, but do not move the cursor.
+
+`downcase-word (M-l)'
+     Lowercase the current (or following) word.  With a negative
+     argument, lowercase the previous word, but do not move the cursor.
+
+`capitalize-word (M-c)'
+     Capitalize the current (or following) word.  With a negative
+     argument, capitalize the previous word, but do not move the cursor.
+
+`overwrite-mode ()'
+     Toggle overwrite mode.  With an explicit positive numeric argument,
+     switches to overwrite mode.  With an explicit non-positive numeric
+     argument, switches to insert mode.  This command affects only
+     `emacs' mode; `vi' mode does overwrite differently.  Each call to
+     `readline()' starts in insert mode.
+
+     In overwrite mode, characters bound to `self-insert' replace the
+     text at point rather than pushing the text to the right.
+     Characters bound to `backward-delete-char' replace the character
+     before point with a space.
+
+     By default, this command is unbound.

+
+Killing And Yanking
+-------------------
+
+`kill-line (C-k)'
+     Kill the text from point to the end of the line.
+
+`backward-kill-line (C-x Rubout)'
+     Kill backward to the beginning of the line.
+
+`unix-line-discard (C-u)'
+     Kill backward from the cursor to the beginning of the current line.
+
+`kill-whole-line ()'
+     Kill all characters on the current line, no matter where point is.
+     By default, this is unbound.
+
+`kill-word (M-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as `forward-word'.
+
+`backward-kill-word (M-<DEL>)'
+     Kill the word behind point.  Word boundaries are the same as
+     `backward-word'.
+
+`unix-word-rubout (C-w)'
+     Kill the word behind point, using white space as a word boundary.
+     The killed text is saved on the kill-ring.
+
+`delete-horizontal-space ()'
+     Delete all spaces and tabs around point.  By default, this is
+     unbound.
+
+`kill-region ()'
+     Kill the text in the current region.  By default, this command is
+     unbound.
+
+`copy-region-as-kill ()'
+     Copy the text in the region to the kill buffer, so it can be yanked
+     right away.  By default, this command is unbound.
+
+`copy-backward-word ()'
+     Copy the word before point to the kill buffer.  The word
+     boundaries are the same as `backward-word'.  By default, this
+     command is unbound.
+
+`copy-forward-word ()'
+     Copy the word following point to the kill buffer.  The word
+     boundaries are the same as `forward-word'.  By default, this
+     command is unbound.
+
+`yank (C-y)'
+     Yank the top of the kill ring into the buffer at point.
+
+`yank-pop (M-y)'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `yank' or `yank-pop'.

+
+Specifying Numeric Arguments
+----------------------------
+
+`digit-argument (M-0, M-1, ... M--)'
+     Add this digit to the argument already accumulating, or start a new
+     argument.  `M--' starts a negative argument.
+
+`universal-argument ()'
+     This is another way to specify an argument.  If this command is
+     followed by one or more digits, optionally with a leading minus
+     sign, those digits define the argument.  If the command is
+     followed by digits, executing `universal-argument' again ends the
+     numeric argument, but is otherwise ignored.  As a special case, if
+     this command is immediately followed by a character that is
+     neither a digit or minus sign, the argument count for the next
+     command is multiplied by four.  The argument count is initially
+     one, so executing this function the first time makes the argument
+     count four, a second time makes the argument count sixteen, and so
+     on.  By default, this is not bound to a key.
+
+
+File: readline.info,  Node: Commands For Completion,  Next: Keyboard Macros,  Prev: Numeric Arguments,  Up: Bindable Readline Commands
+
+Letting Readline Type For You
+-----------------------------
+
+`complete (<TAB>)'
+     Attempt to perform completion on the text before point.  The
+     actual completion performed is application-specific.  The default
+     is filename completion.
+
+`possible-completions (M-?)'
+     List the possible completions of the text before point.
+
+`insert-completions (M-*)'
+     Insert all completions of the text before point that would have
+     been generated by `possible-completions'.
+
+`menu-complete ()'
+     Similar to `complete', but replaces the word to be completed with
+     a single match from the list of possible completions.  Repeated
+     execution of `menu-complete' steps through the list of possible
+     completions, inserting each match in turn.  At the end of the list
+     of completions, the bell is rung (subject to the setting of
+     `bell-style') and the original text is restored.  An argument of N
+     moves N positions forward in the list of matches; a negative
+     argument may be used to move backward through the list.  This
+     command is intended to be bound to <TAB>, but is unbound by
+     default.
+
+`delete-char-or-list ()'
+     Deletes the character under the cursor if not at the beginning or
+     end of the line (like `delete-char').  If at the end of the line,
+     behaves identically to `possible-completions'.  This command is
+     unbound by default.

+
+Keyboard Macros
+---------------
+
+`start-kbd-macro (C-x ()'
+     Begin saving the characters typed into the current keyboard macro.
+
+`end-kbd-macro (C-x ))'
+     Stop saving the characters typed into the current keyboard macro
+     and save the definition.
+
+`call-last-kbd-macro (C-x e)'
+     Re-execute the last keyboard macro defined, by making the
+     characters in the macro appear as if typed at the keyboard.
+
+
+File: readline.info,  Node: Miscellaneous Commands,  Prev: Keyboard Macros,  Up: Bindable Readline Commands
+
+Some Miscellaneous Commands
+---------------------------
+
+`re-read-init-file (C-x C-r)'
+     Read in the contents of the INPUTRC file, and incorporate any
+     bindings or variable assignments found there.
+
+`abort (C-g)'
+     Abort the current editing command and ring the terminal's bell
+     (subject to the setting of `bell-style').
+
+`do-uppercase-version (M-a, M-b, M-X, ...)'
+     If the metafied character X is lowercase, run the command that is
+     bound to the corresponding uppercase character.
+
+`prefix-meta (<ESC>)'
+     Metafy the next character typed.  This is for keyboards without a
+     meta key.  Typing `<ESC> f' is equivalent to typing `M-f'.
+
+`undo (C-_ or C-x C-u)'
+     Incremental undo, separately remembered for each line.
+
+`revert-line (M-r)'
+     Undo all changes made to this line.  This is like executing the
+     `undo' command enough times to get back to the beginning.
+
+`tilde-expand (M-~)'
+     Perform tilde expansion on the current word.
+
+`set-mark (C-@)'
+     Set the mark to the point.  If a numeric argument is supplied, the
+     mark is set to that position.
+
+`exchange-point-and-mark (C-x C-x)'
+     Swap the point with the mark.  The current cursor position is set
+     to the saved position, and the old cursor position is saved as the
+     mark.
+
+`character-search (C-])'
+     A character is read and point is moved to the next occurrence of
+     that character.  A negative count searches for previous
+     occurrences.
+
+`character-search-backward (M-C-])'
+     A character is read and point is moved to the previous occurrence
+     of that character.  A negative count searches for subsequent
+     occurrences.
+
+`insert-comment (M-#)'
+     Without a numeric argument, the value of the `comment-begin'
+     variable is inserted at the beginning of the current line.  If a
+     numeric argument is supplied, this command acts as a toggle:  if
+     the characters at the beginning of the line do not match the value
+     of `comment-begin', the value is inserted, otherwise the
+     characters in `comment-begin' are deleted from the beginning of
+     the line.  In either case, the line is accepted as if a newline
+     had been typed.
+
+`dump-functions ()'
+     Print all of the functions and their key bindings to the Readline
+     output stream.  If a numeric argument is supplied, the output is
+     formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+`dump-variables ()'
+     Print all of the settable variables and their values to the
+     Readline output stream.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`dump-macros ()'
+     Print all of the Readline key sequences bound to macros and the
+     strings they output.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`emacs-editing-mode (C-e)'
+     When in `vi' command mode, this causes a switch to `emacs' editing
+     mode.
+
+`vi-editing-mode (M-C-j)'
+     When in `emacs' editing mode, this causes a switch to `vi' editing
+     mode.
+
+
+File: readline.info,  Node: Readline vi Mode,  Prev: Bindable Readline Commands,  Up: Command Line Editing
+
+Readline vi Mode
+================
+
+   While the Readline library does not have a full set of `vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline `vi' mode behaves as specified in the POSIX 1003.2
+standard.
+
+   In order to switch interactively between `emacs' and `vi' editing
+modes, use the command `M-C-j' (bound to emacs-editing-mode when in
+`vi' mode and to vi-editing-mode in `emacs' mode).  The Readline
+default is `emacs' mode.
+
+   When you enter a line in `vi' mode, you are already placed in
+`insertion' mode, as if you had typed an `i'.  Pressing <ESC> switches
+you into `command' mode, where you can edit the text of the line with
+the standard `vi' movement keys, move to previous history lines with
+`k' and subsequent lines with `j', and so forth.

+Programming with GNU Readline
+*****************************
+
+   This chapter describes the interface between the GNU Readline
+Library and other programs.  If you are a programmer, and you wish to
+include the features found in GNU Readline such as completion, line
+editing, and interactive history manipulation in your own programs,
+this section is for you.

+
+Basic Behavior
+==============
+
+   Many programs provide a command line interface, such as `mail',
+`ftp', and `sh'.  For such programs, the default behaviour of Readline
+is sufficient.  This section describes how to use Readline in the
+simplest way possible, perhaps to replace calls in your code to
+`gets()' or `fgets()'.
+
+   The function `readline()' prints a prompt PROMPT and then reads and
+returns a single line of text from the user.  If PROMPT is `NULL' or
+the empty string, no prompt is displayed.  The line `readline' returns
+is allocated with `malloc()'; the caller should `free()' the line when
+it has finished with it.  The declaration for `readline' in ANSI C is
+
+     `char *readline (const char *PROMPT);'
+
+So, one might say
+     `char *line = readline ("Enter a line: ");'
+
+in order to read a line of text from the user.  The line returned has
+the final newline removed, so only the text remains.
+
+   If `readline' encounters an `EOF' while reading the line, and the
+line is empty at that point, then `(char *)NULL' is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+   If you want the user to be able to get at the line later, (with
+<C-p> for example), you must call `add_history()' to save the line away
+in a "history" list of such lines.
+
+     `add_history (line)';
+
+For full details on the GNU History Library, see the associated manual.
+
+   It is preferable to avoid saving empty lines on the history list,
+since users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard `gets()' library
+function, and has the advantage of no static buffer to overflow:
+
+     /* A static variable for holding the line. */
+     static char *line_read = (char *)NULL;
+     
+     /* Read a string, and return a pointer to it.
+        Returns NULL on EOF. */
+     char *
+     rl_gets ()
+     {
+       /* If the buffer has already been allocated,
+          return the memory to the free pool. */
+       if (line_read)
+         {
+           free (line_read);
+           line_read = (char *)NULL;
+         }
+     
+       /* Get a line from the user. */
+       line_read = readline ("");
+     
+       /* If the line has any text in it,
+          save it on the history. */
+       if (line_read && *line_read)
+         add_history (line_read);
+     
+       return (line_read);
+     }
+
+   This function gives the user the default behaviour of <TAB>
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the <TAB> key with
+`rl_bind_key()'.
+
+     `int rl_bind_key (int KEY, rl_command_func_t *FUNCTION);'
+
+   `rl_bind_key()' takes two arguments: KEY is the character that you
+want to bind, and FUNCTION is the address of the function to call when
+KEY is pressed.  Binding <TAB> to `rl_insert()' makes <TAB> insert
+itself.  `rl_bind_key()' returns non-zero if KEY is not a valid ASCII
+character code (between 0 and 255).
+
+   Thus, to disable the default <TAB> behavior, the following suffices:
+     `rl_bind_key ('\t', rl_insert);'
+
+   This code should be executed once at the start of your program; you
+might write a function called `initialize_readline()' which performs
+this and other desired initializations, such as installing custom
+completers (*note Custom Completers::).

+
+Custom Functions
+================
+
+   Readline provides many functions for manipulating the text of the
+line, but it isn't possible to anticipate the needs of all programs.
+This section describes the various functions and variables defined
+within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+   Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an application
+writer should include the file `<readline/readline.h>' in any file that
+uses Readline's features.  Since some of the definitions in
+`readline.h' use the `stdio' library, the file `<stdio.h>' should be
+included before `readline.h'.
+
+   `readline.h' defines a C preprocessor variable that should be
+treated as an integer, `RL_READLINE_VERSION', which may be used to
+conditionally compile application code depending on the installed
+Readline version.  The value is a hexadecimal encoding of the major and
+minor version numbers of the library, of the form 0xMMMM.  MM is the
+two-digit major version number; MM is the two-digit minor version
+number.  For Readline 4.2, for example, the value of
+`RL_READLINE_VERSION' would be `0x0402'.

+
+Readline Typedefs
+-----------------
+
+   For readabilty, we declare a number of new object types, all pointers
+to functions.
+
+   The reason for declaring these new types is to make it easier to
+write code describing pointers to C functions with appropriately
+prototyped arguments and return values.
+
+   For instance, say we want to declare a variable FUNC as a pointer to
+a function which takes two `int' arguments and returns an `int' (this
+is the type of all of the Readline bindable functions).  Instead of the
+classic C declaration
+
+   `int (*func)();'
+
+or the ANSI-C style declaration
+
+   `int (*func)(int, int);'
+
+we may write
+
+   `rl_command_func_t *func;'
+
+   The full list of function pointer types available is
+
+`typedef int rl_command_func_t (int, int);'
+
+`typedef char *rl_compentry_func_t (const char *, int);'
+
+`typedef char **rl_completion_func_t (const char *, int, int);'
+
+`typedef char *rl_quote_func_t (char *, int, char *);'
+
+`typedef char *rl_dequote_func_t (char *, int);'
+
+`typedef int rl_compignore_func_t (char **);'
+
+`typedef void rl_compdisp_func_t (char **, int, int);'
+
+`typedef int rl_hook_func_t (void);'
+
+`typedef int rl_getc_func_t (FILE *);'
+
+`typedef int rl_linebuf_func_t (char *, int);'
+
+`typedef int rl_intfunc_t (int);'
+
+`#define rl_ivoidfunc_t rl_hook_func_t'
+
+`typedef int rl_icpfunc_t (char *);'
+
+`typedef int rl_icppfunc_t (char **);'
+
+`typedef void rl_voidfunc_t (void);'
+
+`typedef void rl_vintfunc_t (int);'
+
+`typedef void rl_vcpfunc_t (char *);'
+
+`typedef void rl_vcppfunc_t (char **);'

+
+Writing a New Function
+----------------------
+
+   In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+   The calling sequence for a command `foo' looks like
+
+     `int foo (int count, int key)'
+
+where COUNT is the numeric argument (or 1 if defaulted) and KEY is the
+key that invoked this function.
+
+   It is completely up to the function as to what should be done with
+the numeric argument.  Some functions use it as a repeat count, some as
+a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a function uses the numeric argument as a
+repeat count, it should be able to do something useful with both
+negative and positive arguments.  At the very least, it should be aware
+that it can be passed a negative argument.
+
+   A command function should return 0 if its action completes
+successfully, and a non-zero value if some error occurs.
+
+

+
+Readline Variables
+==================
+
+   These variables are available to function writers.
+
+ - Variable: char * rl_line_buffer
+     This is the line gathered so far.  You are welcome to modify the
+     contents of the line, but see *Note Allowing Undoing::.  The
+     function `rl_extend_line_buffer' is available to increase the
+     memory allocated to `rl_line_buffer'.
+
+ - Variable: int rl_point
+     The offset of the current cursor position in `rl_line_buffer' (the
+     _point_).
+
+ - Variable: int rl_end
+     The number of characters present in `rl_line_buffer'.  When
+     `rl_point' is at the end of the line, `rl_point' and `rl_end' are
+     equal.
+
+ - Variable: int rl_mark
+     The MARK (saved position) in the current line.  If set, the mark
+     and point define a _region_.
+
+ - Variable: int rl_done
+     Setting this to a non-zero value causes Readline to return the
+     current line immediately.
+
+ - Variable: int rl_num_chars_to_read
+     Setting this to a positive value before calling `readline()' causes
+     Readline to return after accepting that many characters, rather
+     than reading up to a character bound to `accept-line'.
+
+ - Variable: int rl_pending_input
+     Setting this to a value makes it the next keystroke read.  This is
+     a way to stuff a single character into the input stream.
+
+ - Variable: int rl_dispatching
+     Set to a non-zero value if a function is being called from a key
+     binding; zero otherwise.  Application functions can test this to
+     discover whether they were called directly or by Readline's
+     dispatching mechanism.
+
+ - Variable: int rl_erase_empty_line
+     Setting this to a non-zero value causes Readline to completely
+     erase the current line, including any prompt, any time a newline
+     is typed as the only character on an otherwise-empty line.  The
+     cursor is moved to the beginning of the newly-blank line.
+
+ - Variable: char * rl_prompt
+     The prompt Readline uses.  This is set from the argument to
+     `readline()', and should not be assigned to directly.  The
+     `rl_set_prompt()' function (*note Redisplay::) may be used to
+     modify the prompt string after calling `readline()'.
+
+ - Variable: int rl_already_prompted
+     If an application wishes to display the prompt itself, rather than
+     have Readline do it the first time `readline()' is called, it
+     should set this variable to a non-zero value after displaying the
+     prompt.  The prompt must also be passed as the argument to
+     `readline()' so the redisplay functions can update the display
+     properly.  The calling application is responsible for managing the
+     value; Readline never sets it.
+
+ - Variable: const char * rl_library_version
+     The version number of this revision of the library.
+
+ - Variable: int rl_readline_version
+     An integer encoding the current version of the library.  The
+     encoding is of the form 0xMMMM, where MM is the two-digit major
+     version number, and MM is the two-digit minor version number.  For
+     example, for Readline-4.2, `rl_readline_version' would have the
+     value 0x0402.
+
+ - Variable: int rl_gnu_readline_p
+     Always set to 1, denoting that this is GNU readline rather than
+     some emulation.
+
+ - Variable: const char * rl_terminal_name
+     The terminal type, used for initialization.  If not set by the
+     application, Readline sets this to the value of the `TERM'
+     environment variable the first time it is called.
+
+ - Variable: const char * rl_readline_name
+     This variable is set to a unique name by each application using
+     Readline.  The value allows conditional parsing of the inputrc file
+     (*note Conditional Init Constructs::).
+
+ - Variable: FILE * rl_instream
+     The stdio stream from which Readline reads input.  If `NULL',
+     Readline defaults to STDIN.
+
+ - Variable: FILE * rl_outstream
+     The stdio stream to which Readline performs output.  If `NULL',
+     Readline defaults to STDOUT.
+
+ - Variable: rl_command_func_t * rl_last_func
+     The address of the last command function Readline executed.  May
+     be used to test whether or not a function is being executed twice
+     in succession, for example.
+
+ - Variable: rl_hook_func_t * rl_startup_hook
+     If non-zero, this is the address of a function to call just before
+     `readline' prints the first prompt.
+
+ - Variable: rl_hook_func_t * rl_pre_input_hook
+     If non-zero, this is the address of a function to call after the
+     first prompt has been printed and just before `readline' starts
+     reading input characters.
+
+ - Variable: rl_hook_func_t * rl_event_hook
+     If non-zero, this is the address of a function to call periodically
+     when Readline is waiting for terminal input.  By default, this
+     will be called at most ten times a second if there is no keyboard
+     input.
+
+ - Variable: rl_getc_func_t * rl_getc_function
+     If non-zero, Readline will call indirectly through this pointer to
+     get a character from the input stream.  By default, it is set to
+     `rl_getc', the default Readline character input function (*note
+     Character Input::).
+
+ - Variable: rl_voidfunc_t * rl_redisplay_function
+     If non-zero, Readline will call indirectly through this pointer to
+     update the display with the current contents of the editing buffer.
+     By default, it is set to `rl_redisplay', the default Readline
+     redisplay function (*note Redisplay::).
+
+ - Variable: rl_vintfunc_t * rl_prep_term_function
+     If non-zero, Readline will call indirectly through this pointer to
+     initialize the terminal.  The function takes a single argument, an
+     `int' flag that says whether or not to use eight-bit characters.
+     By default, this is set to `rl_prep_terminal' (*note Terminal
+     Management::).
+
+ - Variable: rl_voidfunc_t * rl_deprep_term_function
+     If non-zero, Readline will call indirectly through this pointer to
+     reset the terminal.  This function should undo the effects of
+     `rl_prep_term_function'.  By default, this is set to
+     `rl_deprep_terminal' (*note Terminal Management::).

+ - Variable: Keymap rl_executing_keymap
+     This variable is set to the keymap (*note Keymaps::) in which the
+     currently executing readline function was found.
+
+ - Variable: Keymap rl_binding_keymap
+     This variable is set to the keymap (*note Keymaps::) in which the
+     last key binding occurred.
+
+ - Variable: char * rl_executing_macro
+     This variable is set to the text of any currently-executing macro.
+
+ - Variable: int rl_readline_state
+     A variable with bit values that encapsulate the current Readline
+     state.  A bit is set with the `RL_SETSTATE' macro, and unset with

+
+Naming a Function
+-----------------
+
+   The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+
+     Meta-Rubout:	backward-kill-word
+
+   This binds the keystroke <Meta-Rubout> to the function
+_descriptively_ named `backward-kill-word'.  You, as the programmer,
+should bind the functions you write to descriptive names as well.
+Readline provides a function for doing that:
+
+ - Function: int rl_add_defun (const char *name, rl_command_func_t
+          *function, int key)
+     Add NAME to the list of named functions.  Make FUNCTION be the
+     function that gets called.  If KEY is not -1, then bind it to
+     FUNCTION using `rl_bind_key()'.
+
+   Using this function alone is sufficient for most applications.  It is
+the recommended way to add a few functions to the default functions that
+Readline has built in.  If you need to do something other than adding a
+function to Readline, you may need to use the underlying functions
+described below.
+
+
+File: readline.info,  Node: Keymaps,  Next: Binding Keys,  Prev: Function Naming,  Up: Readline Convenience Functions
+
+Selecting a Keymap
+------------------
+
+   Key bindings take place on a "keymap".  The keymap is the
+association between the keys that the user types and the functions that
+get run.  You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+ - Function: Keymap rl_make_bare_keymap (void)
+     Returns a new, empty keymap.  The space for the keymap is
+     allocated with `malloc()'; the caller should free it by calling
+     `rl_discard_keymap()' when done.
+
+ - Function: Keymap rl_copy_keymap (Keymap map)
+     Return a new keymap which is a copy of MAP.
+
+ - Function: Keymap rl_make_keymap (void)
+     Return a new keymap with the printing characters bound to
+     rl_insert, the lowercase Meta characters bound to run their
+     equivalents, and the Meta digits bound to produce numeric
+     arguments.
+
+ - Function: void rl_discard_keymap (Keymap keymap)
+     Free the storage associated with KEYMAP.
+
+   Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+ - Function: Keymap rl_get_keymap (void)
+     Returns the currently active keymap.
+
+ - Function: void rl_set_keymap (Keymap keymap)
+     Makes KEYMAP the currently active keymap.
+
+ - Function: Keymap rl_get_keymap_by_name (const char *name)
+     Return the keymap matching NAME.  NAME is one which would be
+     supplied in a `set keymap' inputrc line (*note Readline Init
+     File::).
+
+ - Function: char * rl_get_keymap_name (Keymap keymap)
+     Return the name matching KEYMAP.  NAME is one which would be
+     supplied in a `set keymap' inputrc line (*note Readline Init
+     File::).
+
+
+File: readline.info,  Node: Binding Keys,  Next: Associating Function Names and Bindings,  Prev: Keymaps,  Up: Readline Convenience Functions
+
+Binding Keys
+------------
+
+   Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: `emacs_standard_keymap',
+`emacs_meta_keymap', `emacs_ctlx_keymap', `vi_movement_keymap', and
+`vi_insertion_keymap'.  `emacs_standard_keymap' is the default, and the
+examples in this manual assume that.
+
+   Since `readline()' installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to `readline()' will be overridden.  An
+alternate mechanism is to install custom key bindings in an
+initialization function assigned to the `rl_startup_hook' variable
+(*note Readline Variables::).
+
+   These functions manage key bindings.
+
+ - Function: int rl_bind_key (int key, rl_command_func_t *function)
+     Binds KEY to FUNCTION in the currently active keymap.  Returns
+     non-zero in the case of an invalid KEY.
+
+ - Function: int rl_bind_key_in_map (int key, rl_command_func_t
+          *function, Keymap map)
+     Bind KEY to FUNCTION in MAP.  Returns non-zero in the case of an
+     invalid KEY.
+
+ - Function: int rl_unbind_key (int key)
+     Bind KEY to the null function in the currently active keymap.
+     Returns non-zero in case of error.
+
+ - Function: int rl_unbind_key_in_map (int key, Keymap map)
+     Bind KEY to the null function in MAP.  Returns non-zero in case of
+     error.
+
+ - Function: int rl_unbind_function_in_map (rl_command_func_t
+          *function, Keymap map)
+     Unbind all keys that execute FUNCTION in MAP.
+
+ - Function: int rl_unbind_command_in_map (const char *command, Keymap
+          map)
+     Unbind all keys that are bound to COMMAND in MAP.
+
+ - Function: int rl_set_key (const char *keyseq, rl_command_func_t
+          *function, Keymap map)
+     Bind the key sequence represented by the string KEYSEQ to the
+     function FUNCTION.  This makes new keymaps as necessary.  The
+     initial keymap in which to do bindings is MAP.
+
+ - Function: int rl_generic_bind (int type, const char *keyseq, char
+          *data, Keymap map)
+     Bind the key sequence represented by the string KEYSEQ to the
+     arbitrary pointer DATA.  TYPE says what kind of data is pointed to
+     by DATA; this can be a function (`ISFUNC'), a macro (`ISMACR'), or
+     a keymap (`ISKMAP').  This makes new keymaps as necessary.  The
+     initial keymap in which to do bindings is MAP.
+
+ - Function: int rl_parse_and_bind (char *line)
+     Parse LINE as if it had been read from the `inputrc' file and
+     perform any key bindings and variable assignments found (*note
+     Readline Init File::).
+
+ - Function: int rl_read_init_file (const char *filename)
+     Read keybindings and variable assignments from FILENAME (*note
+     Readline Init File::).
+
+
+File: readline.info,  Node: Associating Function Names and Bindings,  Next: Allowing Undoing,  Prev: Binding Keys,  Up: Readline Convenience Functions
+
+Associating Function Names and Bindings
+---------------------------------------
+
+   These functions allow you to find out what keys invoke named
+functions and the functions invoked by a particular key sequence.  You
+may also associate a new function name with an arbitrary function.
+
+ - Function: rl_command_func_t * rl_named_function (const char *name)
+     Return the function with name NAME.
+
+ - Function: rl_command_func_t * rl_function_of_keyseq (const char
+          *keyseq, Keymap map, int *type)
+     Return the function invoked by KEYSEQ in keymap MAP.  If MAP is
+     `NULL', the current keymap is used.  If TYPE is not `NULL', the
+     type of the object is returned in the `int' variable it points to
+     (one of `ISFUNC', `ISKMAP', or `ISMACR').
+
+ - Function: char ** rl_invoking_keyseqs (rl_command_func_t *function)
+     Return an array of strings representing the key sequences used to
+     invoke FUNCTION in the current keymap.
+
+ - Function: char ** rl_invoking_keyseqs_in_map (rl_command_func_t
+          *function, Keymap map)
+     Return an array of strings representing the key sequences used to
+     invoke FUNCTION in the keymap MAP.
+
+ - Function: void rl_function_dumper (int readable)
+     Print the readline function names and the key sequences currently
+     bound to them to `rl_outstream'.  If READABLE is non-zero, the
+     list is formatted in such a way that it can be made part of an
+     `inputrc' file and re-read.
+
+ - Function: void rl_list_funmap_names (void)
+     Print the names of all bindable Readline functions to
+     `rl_outstream'.
+
+ - Function: const char ** rl_funmap_names (void)
+     Return a NULL terminated array of known function names.  The array
+     is sorted.  The array itself is allocated, but not the strings
+     inside.  You should `free()' the array when you are done, but not
+     the pointers.
+
+ - Function: int rl_add_funmap_entry (const char *name,
+          rl_command_func_t *function)
+     Add NAME to the list of bindable Readline command names, and make
+     FUNCTION the function to be called when NAME is invoked.
+
+
+File: readline.info,  Node: Allowing Undoing,  Next: Redisplay,  Prev: Associating Function Names and Bindings,  Up: Readline Convenience Functions
+
+Allowing Undoing
+----------------
+
+   Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try something if
+you know you can undo it.
+
+   If your function simply inserts text once, or deletes text once, and
+uses `rl_insert_text()' or `rl_delete_text()' to do it, then undoing is
+already done for you automatically.
+
+   If you do multiple insertions or multiple deletions, or any
+combination of these operations, you should group them together into
+one operation.  This is done with `rl_begin_undo_group()' and
+`rl_end_undo_group()'.
+
+   The types of events that can be undone are:
+
+     enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END };
+
+   Notice that `UNDO_DELETE' means to insert some text, and
+`UNDO_INSERT' means to delete some text.  That is, the undo code tells
+what to undo, not how to undo it.  `UNDO_BEGIN' and `UNDO_END' are tags
+added by `rl_begin_undo_group()' and `rl_end_undo_group()'.
+
+ - Function: int rl_begin_undo_group (void)
+     Begins saving undo information in a group construct.  The undo
+     information usually comes from calls to `rl_insert_text()' and
+     `rl_delete_text()', but could be the result of calls to
+     `rl_add_undo()'.
+
+ - Function: int rl_end_undo_group (void)
+     Closes the current undo group started with `rl_begin_undo_group
+     ()'.  There should be one call to `rl_end_undo_group()' for each
+     call to `rl_begin_undo_group()'.
+
+ - Function: void rl_add_undo (enum undo_code what, int start, int end,
+          char *text)
+     Remember how to undo an event (according to WHAT).  The affected
+     text runs from START to END, and encompasses TEXT.
+
+ - Function: void rl_free_undo_list (void)
+     Free the existing undo list.
+
+ - Function: int rl_do_undo (void)
+     Undo the first thing on the undo list.  Returns `0' if there was
+     nothing to undo, non-zero if something was undone.
+
+   Finally, if you neither insert nor delete text, but directly modify
+the existing text (e.g., change its case), call `rl_modifying()' once,
+just before you modify the text.  You must supply the indices of the
+text range that you are going to modify.
+
+ - Function: int rl_modifying (int start, int end)
+     Tell Readline to save the text between START and END as a single
+     undo unit.  It is assumed that you will subsequently modify that
+     text.
+
+
+File: readline.info,  Node: Redisplay,  Next: Modifying Text,  Prev: Allowing Undoing,  Up: Readline Convenience Functions
+
+Redisplay
+---------
+
+ - Function: void rl_redisplay (void)
+     Change what's displayed on the screen to reflect the current
+     contents of `rl_line_buffer'.
+
+ - Function: int rl_forced_update_display (void)
+     Force the line to be updated and redisplayed, whether or not
+     Readline thinks the screen display is correct.
+
+ - Function: int rl_on_new_line (void)
+     Tell the update functions that we have moved onto a new (empty)
+     line, usually after ouputting a newline.
+
+ - Function: int rl_on_new_line_with_prompt (void)
+     Tell the update functions that we have moved onto a new line, with
+     RL_PROMPT already displayed.  This could be used by applications
+     that want to output the prompt string themselves, but still need
+     Readline to know the prompt string length for redisplay.  It
+     should be used after setting RL_ALREADY_PROMPTED.
+
+ - Function: int rl_reset_line_state (void)
+     Reset the display state to a clean state and redisplay the current
+     line starting on a new line.
+
+ - Function: int rl_crlf (void)
+     Move the cursor to the start of the next screen line.
+
+ - Function: int rl_show_char (int c)
+     Display character C on `rl_outstream'.  If Readline has not been
+     set to display meta characters directly, this will convert meta
+     characters to a meta-prefixed key sequence.  This is intended for
+     use by applications which wish to do their own redisplay.
+
+ - Function: int rl_message (const char *, ...)
+     The arguments are a format string as would be supplied to `printf',
+     possibly containing conversion specifications such as `%d', and
+     any additional arguments necessary to satisfy the conversion
+     specifications.  The resulting string is displayed in the "echo
+     area".  The echo area is also used to display numeric arguments
+     and search strings.
+
+ - Function: int rl_clear_message (void)
+     Clear the message in the echo area.
+
+ - Function: void rl_save_prompt (void)
+     Save the local Readline prompt display state in preparation for
+     displaying a new message in the message area with `rl_message()'.
+
+ - Function: void rl_restore_prompt (void)
+     Restore the local Readline prompt display state saved by the most
+     recent call to `rl_save_prompt'.
+
+ - Function: int rl_expand_prompt (char *prompt)
+     Expand any special character sequences in PROMPT and set up the
+     local Readline prompt redisplay variables.  This function is
+     called by `readline()'.  It may also be called to expand the
+     primary prompt if the `rl_on_new_line_with_prompt()' function or
+     `rl_already_prompted' variable is used.  It returns the number of
+     visible characters on the last line of the (possibly multi-line)
+     prompt.
+
+ - Function: int rl_set_prompt (const char *prompt)
+     Make Readline use PROMPT for subsequent redisplay.  This calls
+     `rl_expand_prompt()' to expand the prompt and sets `rl_prompt' to
+     the result.

+Modifying Text
+--------------
+
+ - Function: int rl_insert_text (const char *text)
+     Insert TEXT into the line at the current cursor position.  Returns
+     the number of characters inserted.
+
+ - Function: int rl_delete_text (int start, int end)
+     Delete the text between START and END in the current line.
+     Returns the number of characters deleted.
+
+ - Function: char * rl_copy_text (int start, int end)
+     Return a copy of the text between START and END in the current
+     line.
+
+ - Function: int rl_kill_text (int start, int end)
+     Copy the text between START and END in the current line to the
+     kill ring, appending or prepending to the last kill if the last
+     command was a kill command.  The text is deleted.  If START is
+     less than END, the text is appended, otherwise prepended.  If the
+     last command was not a kill, a new kill ring slot is used.
+
+ - Function: int rl_push_macro_input (char *macro)
+     Cause MACRO to be inserted into the line, as if it had been invoked
+     by a key bound to a macro.  Not especially useful; use
+     `rl_insert_text()' instead.
+
+
+File: readline.info,  Node: Character Input,  Next: Terminal Management,  Prev: Modifying Text,  Up: Readline Convenience Functions
+
+Character Input
+---------------
+
+ - Function: int rl_read_key (void)
+     Return the next character available from Readline's current input
+     stream.  This handles input inserted into the input stream via
+     RL_PENDING_INPUT (*note Readline Variables::) and
+     `rl_stuff_char()', macros, and characters read from the keyboard.
+     While waiting for input, this function will call any function
+     assigned to the `rl_event_hook' variable.
+
+ - Function: int rl_getc (FILE *stream)
+     Return the next character available from STREAM, which is assumed
+     to be the keyboard.
+
+ - Function: int rl_stuff_char (int c)
+     Insert C into the Readline input stream.  It will be "read" before
+     Readline attempts to read characters from the terminal with
+     `rl_read_key()'.  Up to 512 characters may be pushed back.
+     `rl_stuff_char' returns 1 if the character was successfully
+     inserted; 0 otherwise.
+
+ - Function: int rl_execute_next (int c)
+     Make C be the next command to be executed when `rl_read_key()' is
+     called.  This sets RL_PENDING_INPUT.
+
+ - Function: int rl_clear_pending_input (void)
+     Unset RL_PENDING_INPUT, effectively negating the effect of any
+     previous call to `rl_execute_next()'.  This works only if the
+     pending input has not already been read with `rl_read_key()'.
+
+ - Function: int rl_set_keyboard_input_timeout (int u)
+     While waiting for keyboard input in `rl_read_key()', Readline will

+Terminal Management
+-------------------
+
+ - Function: void rl_prep_terminal (int meta_flag)
+     Modify the terminal settings for Readline's use, so `readline()'
+     can read a single character at a time from the keyboard.  The
+     META_FLAG argument should be non-zero if Readline should read
+     eight-bit input.
+
+ - Function: void rl_deprep_terminal (void)
+     Undo the effects of `rl_prep_terminal()', leaving the terminal in
+     the state in which it was before the most recent call to
+     `rl_prep_terminal()'.
+
+ - Function: void rl_tty_set_default_bindings (Keymap kmap)
+     Read the operating system's terminal editing characters (as would
+     be displayed by `stty') to their Readline equivalents.  The
+     bindings are performed in KMAP.
+
+ - Function: int rl_reset_terminal (const char *terminal_name)
+     Reinitialize Readline's idea of the terminal settings using
+     TERMINAL_NAME as the terminal type (e.g., `vt100').  If
+     TERMINAL_NAME is `NULL', the value of the `TERM' environment
+     variable is used.

+Utility Functions
+-----------------
+
+ - Function: void rl_replace_line (const char *text, int clear_undo)
+     Replace the contents of `rl_line_buffer' with TEXT.  The point and
+     mark are preserved, if possible.  If CLEAR_UNDO is non-zero, the
+     undo list associated with the current line is cleared.
+
+ - Function: int rl_extend_line_buffer (int len)
+     Ensure that `rl_line_buffer' has enough space to hold LEN
+     characters, possibly reallocating it if necessary.
+
+ - Function: int rl_initialize (void)
+     Initialize or re-initialize Readline's internal state.  It's not
+     strictly necessary to call this; `readline()' calls it before
+     reading any input.
+
+ - Function: int rl_ding (void)
+     Ring the terminal bell, obeying the setting of `bell-style'.
+
+ - Function: int rl_alphabetic (int c)
+     Return 1 if C is an alphabetic character.
+
+ - Function: void rl_display_match_list (char **matches, int len, int
+          max)
+     A convenience function for displaying a list of strings in
+     columnar format on Readline's output stream.  `matches' is the list
+     of strings, in argv format, such as a list of completion matches.
+     `len' is the number of strings in `matches', and `max' is the
+     length of the longest string in `matches'.  This function uses the
+     setting of `print-completions-horizontally' to select how the
+     matches are displayed (*note Readline Init File Syntax::).
+
+   The following are implemented as macros, defined in `chardefs.h'.
+Applications should refrain from using them.
+
+ - Function: int _rl_uppercase_p (int c)
+     Return 1 if C is an uppercase alphabetic character.
+
+ - Function: int _rl_lowercase_p (int c)
+     Return 1 if C is a lowercase alphabetic character.
+
+ - Function: int _rl_digit_p (int c)
+     Return 1 if C is a numeric character.

+
+ - Function: int _rl_to_lower (int c)
+     If C is an uppercase alphabetic character, return the corresponding

+Miscellaneous Functions
+-----------------------
+
+ - Function: int rl_macro_bind (const char *keyseq, const char *macro,
+          Keymap map)
+     Bind the key sequence KEYSEQ to invoke the macro MACRO.  The
+     binding is performed in MAP.  When KEYSEQ is invoked, the MACRO
+     will be inserted into the line.  This function is deprecated; use
+     `rl_generic_bind()' instead.
+
+ - Function: void rl_macro_dumper (int readable)
+     Print the key sequences bound to macros and their values, using
+     the current keymap, to `rl_outstream'.  If READABLE is non-zero,
+     the list is formatted in such a way that it can be made part of an
+     `inputrc' file and re-read.
+
+ - Function: int rl_variable_bind (const char *variable, const char
+          *value)
+     Make the Readline variable VARIABLE have VALUE.  This behaves as
+     if the readline command `set VARIABLE VALUE' had been executed in
+     an `inputrc' file (*note Readline Init File Syntax::).
+
+ - Function: void rl_variable_dumper (int readable)
+     Print the readline variable names and their current values to
+     `rl_outstream'.  If READABLE is non-zero, the list is formatted in
+     such a way that it can be made part of an `inputrc' file and
+     re-read.
+
+ - Function: int rl_set_paren_blink_timeout (int u)
+     Set the time interval (in microseconds) that Readline waits when
+     showing a balancing character when `blink-matching-paren' has been
+     enabled.
+
+ - Function: char * rl_get_termcap (const char *cap)
+     Retrieve the string value of the termcap capability CAP.  Readline
+     fetches the termcap entry for the current terminal name and uses
+     those capabilities to move around the screen line and perform other
+     terminal-specific operations, like erasing a line.  Readline does
+     not use all of a terminal's capabilities, and this function will
+     return values for only those capabilities Readline uses.

+
+Alternate Interface
+-------------------
+
+   An alternate interface is available to plain `readline()'.  Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to `select()' on
+various file descriptors.  To accomodate this need, readline can also
+be invoked as a `callback' function from an event loop.  There are
+functions available to make this easy.
+
+ - Function: void rl_callback_handler_install (const char *prompt,
+          rl_vcpfunc_t *lhandler)
+     Set up the terminal for readline I/O and display the initial
+     expanded value of PROMPT.  Save the value of LHANDLER to use as a
+     function to call when a complete line of input has been entered.
+     The function takes the text of the line as an argument.
+
+ - Function: void rl_callback_read_char (void)
+     Whenever an application determines that keyboard input is
+     available, it should call `rl_callback_read_char()', which will
+     read the next character from the current input source.  If that
+     character completes the line, `rl_callback_read_char' will invoke
+     the LHANDLER function saved by `rl_callback_handler_install' to
+     process the line.  Before calling the LHANDLER function, the
+     terminal settings are reset to the values they had before calling
+     `rl_callback_handler_install'.  If the LHANDLER function returns,
+     the terminal settings are modified for Readline's use again.
+     `EOF' is  indicated by calling LHANDLER with a `NULL' line.
+
+ - Function: void rl_callback_handler_remove (void)
+     Restore the terminal to its initial state and remove the line
+     handler.  This may be called from within a callback as well as
+     independently.  If the LHANDLER installed by
+     `rl_callback_handler_install' does not exit the program, either
+     this function or the function referred to by the value of
+     `rl_deprep_term_function' should be called before the program
+     exits to reset the terminal settings.

+
+Readline Signal Handling
+========================
+
+   Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his
+terminal, or a network connection being broken.  There is a class of
+signals that can be sent to the process currently reading input from
+the keyboard.  Since Readline changes the terminal attributes when it
+is called, it needs to perform special processing when such a signal is
+received in order to restore the terminal to a sane state, or provide
+application writers with functions to do so manually.
+
+   Readline contains an internal signal handler that is installed for a
+number of signals (`SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM',
+`SIGTSTP', `SIGTTIN', and `SIGTTOU').  When one of these signals is
+received, the signal handler will reset the terminal attributes to
+those that were in effect before `readline()' was called, reset the
+signal handling to what it was before `readline()' was called, and
+resend the signal to the calling application.  If and when the calling
+application's signal handler returns, Readline will reinitialize the
+terminal and continue to accept input.  When a `SIGINT' is received,
+the Readline signal handler performs some additional work, which will
+cause any partially-entered line to be aborted (see the description of
+`rl_free_line_state()' below).
+
+   There is an additional Readline signal handler, for `SIGWINCH', which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an `xterm').  The Readline `SIGWINCH'
+handler updates Readline's internal screen size information, and then
+calls any `SIGWINCH' signal handler the calling application has
+installed.  Readline calls the application's `SIGWINCH' signal handler
+without resetting the terminal to its original state.  If the
+application's signal handler does more than update its idea of the
+terminal size and return (for example, a `longjmp' back to a main
+processing loop), it _must_ call `rl_cleanup_after_signal()' (described
+below), to restore the terminal state.
+
+   Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling `readline()', not in a
+signal handler, so Readline's internal signal state is not corrupted.
+
+ - Variable: int rl_catch_signals
+     If this variable is non-zero, Readline will install signal
+     handlers for `SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', `SIGTSTP',
+     `SIGTTIN', and `SIGTTOU'.
+
+     The default value of `rl_catch_signals' is 1.
+
+ - Variable: int rl_catch_sigwinch
+     If this variable is non-zero, Readline will install a signal
+     handler for `SIGWINCH'.
+
+     The default value of `rl_catch_sigwinch' is 1.
+
+   If an application does not wish to have Readline catch any signals,
+or to handle signals other than those Readline catches (`SIGHUP', for
+example), Readline provides convenience functions to do the necessary
+terminal and internal state cleanup upon receipt of a signal.
+
+ - Function: void rl_cleanup_after_signal (void)
+     This function will reset the state of the terminal to what it was
+     before `readline()' was called, and remove the Readline signal
+     handlers for all signals, depending on the values of
+     `rl_catch_signals' and `rl_catch_sigwinch'.
+
+ - Function: void rl_free_line_state (void)
+     This will free any partial state associated with the current input
+     line (undo information, any partial history entry, any
+     partially-entered keyboard macro, and any partially-entered
+     numeric argument).  This should be called before
+     `rl_cleanup_after_signal()'.  The Readline signal handler for
+     `SIGINT' calls this to abort the current input line.
+
+ - Function: void rl_reset_after_signal (void)
+     This will reinitialize the terminal and reinstall any Readline
+     signal handlers, depending on the values of `rl_catch_signals' and
+     `rl_catch_sigwinch'.
+
+   If an application does not wish Readline to catch `SIGWINCH', it may
+call `rl_resize_terminal()' or `rl_set_screen_size()' to force Readline
+to update its idea of the terminal size when a `SIGWINCH' is received.
+
+ - Function: void rl_resize_terminal (void)
+     Update Readline's internal screen size by reading values from the
+     kernel.
+
+ - Function: void rl_set_screen_size (int rows, int cols)
+     Set Readline's idea of the terminal size to ROWS rows and COLS
+     columns.
+
+   If an application does not want to install a `SIGWINCH' handler, but
+is still interested in the screen dimensions, Readline's idea of the
+screen size may be queried.
+
+ - Function: void rl_get_screen_size (int *rows, int *cols)
+     Return Readline's idea of the terminal's size in the variables
+     pointed to by the arguments.
+
+   The following functions install and remove Readline's signal
+handlers.
+
+ - Function: int rl_set_signals (void)
+     Install Readline's signal handler for `SIGINT', `SIGQUIT',
+     `SIGTERM', `SIGALRM', `SIGTSTP', `SIGTTIN', `SIGTTOU', and
+     `SIGWINCH', depending on the values of `rl_catch_signals' and
+     `rl_catch_sigwinch'.
+
+ - Function: int rl_clear_signals (void)
+     Remove all of the Readline signal handlers installed by
+     `rl_set_signals()'.

+Custom Completers
+=================
+
+   Typically, a program that reads commands from the user has a way of
+disambiguating commands and data.  If your program is one of these, then
+it can provide completion for commands, data, or both.  The following
+sections describe how your program and Readline cooperate to provide
+this service.
+
+* Menu:
+
+* How Completing Works::	The logic used to do completion.
+* Completion Functions::	Functions provided by Readline.
+* Completion Variables::	Variables which control completion.
+* A Short Completion Example::	An example of writing completer subroutines.

+
+How Completing Works
+--------------------
+
+   In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately expand a
+partial word without knowing all of the possible words which make sense
+in that context.  The Readline library provides the user interface to
+completion, and two of the most common completion functions:  filename
+and username.  For completing other types of text, you must write your
+own completion function.  This section describes exactly what such
+functions must do, and provides an example.
+
+   There are three major functions used to perform completion:
+
+  1. The user-interface function `rl_complete()'.  This function is
+     called with the same arguments as other bindable Readline
+     functions: COUNT and INVOKING_KEY.  It isolates the word to be
+     completed and calls `rl_completion_matches()' to generate a list
+     of possible completions.  It then either lists the possible
+     completions, inserts the possible completions, or actually
+     performs the completion, depending on which behavior is desired.
+
+  2. The internal function `rl_completion_matches()' uses an
+     application-supplied "generator" function to generate the list of
+     possible matches, and then returns the array of these matches.
+     The caller should place the address of its generator function in
+     `rl_completion_entry_function'.
+
+  3. The generator function is called repeatedly from
+     `rl_completion_matches()', returning a string each time.  The
+     arguments to the generator function are TEXT and STATE.  TEXT is
+     the partial word to be completed.  STATE is zero the first time
+     the function is called, allowing the generator to perform any
+     necessary initialization, and a positive non-zero integer for each
+     subsequent call.  The generator function returns `(char *)NULL' to
+     inform `rl_completion_matches()' that there are no more
+     possibilities left.  Usually the generator function computes the
+     list of possible completions when STATE is zero, and returns them
+     one at a time on subsequent calls.  Each string the generator
+     function returns as a match must be allocated with `malloc()';
+     Readline frees the strings when it has finished with them.
+
+
+ - Function: int rl_complete (int ignore, int invoking_key)
+     Complete the word at or before point.  You have supplied the
+     function that does the initial simple matching selection algorithm
+     (see `rl_completion_matches()').  The default is to do filename
+     completion.
+
+ - Variable: rl_compentry_func_t * rl_completion_entry_function
+     This is a pointer to the generator function for
+     `rl_completion_matches()'.  If the value of
+     `rl_completion_entry_function' is `NULL' then the default filename
+     generator function, `rl_filename_completion_function()', is used.

+
+Completion Functions
+--------------------
+
+   Here is the complete list of callable completion functions present in
+Readline.
+
+ - Function: int rl_complete_internal (int what_to_do)
+     Complete the word at or before point.  WHAT_TO_DO says what to do
+     with the completion.  A value of `?' means list the possible
+     completions.  `TAB' means do standard completion.  `*' means
+     insert all of the possible completions.  `!' means to display all
+     of the possible completions, if there is more than one, as well as
+     performing partial completion.
+
+ - Function: int rl_complete (int ignore, int invoking_key)
+     Complete the word at or before point.  You have supplied the
+     function that does the initial simple matching selection algorithm
+     (see `rl_completion_matches()' and `rl_completion_entry_function').
+     The default is to do filename completion.  This calls
+     `rl_complete_internal()' with an argument depending on
+     INVOKING_KEY.
+
+ - Function: int rl_possible_completions (int count, int invoking_key)
+     List the possible completions.  See description of `rl_complete
+     ()'.  This calls `rl_complete_internal()' with an argument of `?'.
+
+ - Function: int rl_insert_completions (int count, int invoking_key)
+     Insert the list of possible completions into the line, deleting the
+     partially-completed word.  See description of `rl_complete()'.
+     This calls `rl_complete_internal()' with an argument of `*'.
+
+ - Function: int rl_completion_mode (rl_command_func_t *cfunc)
+     Returns the apppriate value to pass to `rl_complete_internal()'
+     depending on whether CFUNC was called twice in succession and the
+     value of the `show-all-if-ambiguous' variable.
+     Application-specific completion functions may use this function to
+     present the same interface as `rl_complete()'.
+
+ - Function: char ** rl_completion_matches (const char *text,
+          rl_compentry_func_t *entry_func)
+     Returns an array of strings which is a list of completions for
+     TEXT.  If there are no completions, returns `NULL'.  The first
+     entry in the returned array is the substitution for TEXT.  The
+     remaining entries are the possible completions.  The array is
+     terminated with a `NULL' pointer.
+
+     ENTRY_FUNC is a function of two args, and returns a `char *'.  The
+     first argument is TEXT.  The second is a state argument; it is
+     zero on the first call, and non-zero on subsequent calls.
+     ENTRY_FUNC returns a `NULL'  pointer to the caller when there are
+     no more matches.
+
+ - Function: char * rl_filename_completion_function (const char *text,
+          int state)
+     A generator function for filename completion in the general case.
+     TEXT is a partial filename.  The Bash source is a useful reference
+     for writing custom completion functions (the Bash completion
+     functions call this and other Readline functions).
+
+ - Function: char * rl_username_completion_function (const char *text,
+          int state)
+     A completion generator for usernames.  TEXT contains a partial
+     username preceded by a random character (usually `~').  As with all
+     completion generators, STATE is zero on the first call and non-zero
+     for subsequent calls.

+
+Completion Variables
+--------------------
+
+ - Variable: rl_compentry_func_t * rl_completion_entry_function
+     A pointer to the generator function for `rl_completion_matches()'.
+     `NULL' means to use `rl_filename_completion_function()', the
+     default filename completer.
+
+ - Variable: rl_completion_func_t * rl_attempted_completion_function
+     A pointer to an alternative function to create matches.  The
+     function is called with TEXT, START, and END.  START and END are
+     indices in `rl_line_buffer' defining the boundaries of TEXT, which
+     is a character string.  If this function exists and returns
+     `NULL', or if this variable is set to `NULL', then `rl_complete()'
+     will call the value of `rl_completion_entry_function' to generate
+     matches, otherwise the array of strings returned will be used.  If
+     this function sets the `rl_attempted_completion_over' variable to
+     a non-zero value, Readline will not perform its default completion
+     even if this function returns no matches.
+
+ - Variable: rl_quote_func_t * rl_filename_quoting_function
+     A pointer to a function that will quote a filename in an
+     application-specific fashion.  This is called if filename
+     completion is being attempted and one of the characters in
+     `rl_filename_quote_characters' appears in a completed filename.
+     The function is called with TEXT, MATCH_TYPE, and QUOTE_POINTER.
+     The TEXT is the filename to be quoted.  The MATCH_TYPE is either
+     `SINGLE_MATCH', if there is only one completion match, or
+     `MULT_MATCH'.  Some functions use this to decide whether or not to
+     insert a closing quote character.  The QUOTE_POINTER is a pointer
+     to any opening quote character the user typed.  Some functions
+     choose to reset this character.
+
+ - Variable: rl_dequote_func_t * rl_filename_dequoting_function
+     A pointer to a function that will remove application-specific
+     quoting characters from a filename before completion is attempted,
+     so those characters do not interfere with matching the text
+     against names in the filesystem.  It is called with TEXT, the text
+     of the word to be dequoted, and QUOTE_CHAR, which is the quoting
+     character that delimits the filename (usually `'' or `"').  If
+     QUOTE_CHAR is zero, the filename was not in an embedded string.
+
+ - Variable: rl_linebuf_func_t * rl_char_is_quoted_p
+     A pointer to a function to call that determines whether or not a
+     specific character in the line buffer is quoted, according to
+     whatever quoting mechanism the program calling Readline uses.  The
+     function is called with two arguments: TEXT, the text of the line,
+     and INDEX, the index of the character in the line.  It is used to
+     decide whether a character found in
+     `rl_completer_word_break_characters' should be used to break words
+     for the completer.
+
+ - Variable: rl_compignore_func_t * rl_ignore_some_completions_function
+     This function, if defined, is called by the completer when real
+     filename completion is done, after all the matching names have
+     been generated.  It is passed a `NULL' terminated array of matches.
+     The first element (`matches[0]') is the maximal substring common
+     to all matches. This function can re-arrange the list of matches
+     as required, but each element deleted from the array must be freed.
+
+ - Variable: rl_icppfunc_t * rl_directory_completion_hook
+     This function, if defined, is allowed to modify the directory
+     portion of filenames Readline completes.  It is called with the
+     address of a string (the current directory name) as an argument,
+     and may modify that string.  If the string is replaced with a new
+     string, the old value should be freed.  Any modified directory
+     name should have a trailing slash.  The modified value will be
+     displayed as part of the completion, replacing the directory
+     portion of the pathname the user typed.  It returns an integer
+     that should be non-zero if the function modifies its directory
+     argument.  It could be used to expand symbolic links or shell
+     variables in pathnames.
+
+ - Variable: rl_compdisp_func_t * rl_completion_display_matches_hook
+     If non-zero, then this is the address of a function to call when
+     completing a word would normally display the list of possible
+     matches.  This function is called in lieu of Readline displaying
+     the list.  It takes three arguments: (`char **'MATCHES, `int'
+     NUM_MATCHES, `int' MAX_LENGTH) where MATCHES is the array of
+     matching strings, NUM_MATCHES is the number of strings in that
+     array, and MAX_LENGTH is the length of the longest string in that
+     array.  Readline provides a convenience function,
+     `rl_display_match_list', that takes care of doing the display to
+     Readline's output stream.  That function may be called from this
+     hook.
+
+ - Variable: const char * rl_basic_word_break_characters
+     The basic list of characters that signal a break between words for
+     the completer routine.  The default value of this variable is the
+     characters which break words for completion in Bash: `"
+     \t\n\"\\'`@$><=;|&{("'.
+
+ - Variable: const char * rl_basic_quote_characters
+     A list of quote characters which can cause a word break.
+
+ - Variable: const char * rl_completer_word_break_characters
+     The list of characters that signal a break between words for
+     `rl_complete_internal()'.  The default list is the value of
+     `rl_basic_word_break_characters'.
+
+ - Variable: const char * rl_completer_quote_characters
+     A list of characters which can be used to quote a substring of the
+     line.  Completion occurs on the entire substring, and within the
+     substring `rl_completer_word_break_characters' are treated as any
+     other character, unless they also appear within this list.
+
+ - Variable: const char * rl_filename_quote_characters
+     A list of characters that cause a filename to be quoted by the
+     completer when they appear in a completed filename.  The default
+     is the null string.
+
+ - Variable: const char * rl_special_prefixes
+     The list of characters that are word break characters, but should
+     be left in TEXT when it is passed to the completion function.
+     Programs can use this to help determine what kind of completing to
+     do.  For instance, Bash sets this variable to "$@" so that it can
+     complete shell variables and hostnames.
+
+ - Variable: int rl_completion_query_items
+     Up to this many items will be displayed in response to a
+     possible-completions call.  After that, we ask the user if she is
+     sure she wants to see them all.  The default value is 100.
+
+ - Variable: int rl_completion_append_character
+     When a single completion alternative matches at the end of the
+     command line, this character is appended to the inserted
+     completion text.  The default is a space character (` ').  Setting
+     this to the null character (`\0') prevents anything being appended
+     automatically.  This can be changed in custom completion functions
+     to provide the "most sensible word separator character" according
+     to an application-specific command line syntax specification.
+
+ - Variable: int rl_completion_suppress_append
+     If non-zero, RL_COMPLETION_APPEND_CHARACTER is not appended to
+     matches at the end of the command line, as described above.  It is
+     set to 0 before any application-specific completion function is
+     called.
+
+ - Variable: int rl_completion_mark_symlink_dirs
+     If non-zero, a slash will be appended to completed filenames that
+     are symbolic links to directory names, subject to the value of the
+     user-settable MARK-DIRECTORIES variable.  This variable exists so
+     that application completion functions can override the user's
+     global preference (set via the MARK-SYMLINKED-DIRECTORIES Readline
+     variable) if appropriate.  This variable is set to the user's
+     preference before any application completion function is called,
+     so unless that function modifies the value, the user's preferences
+     are honored.
+
+ - Variable: int rl_ignore_completion_duplicates
+     If non-zero, then duplicates in the matches are removed.  The
+     default is 1.
+
+ - Variable: int rl_filename_completion_desired
+     Non-zero means that the results of the matches are to be treated as
+     filenames.  This is _always_ zero on entry, and can only be changed
+     within a completion entry generator function.  If it is set to a
+     non-zero value, directory names have a slash appended and Readline
+     attempts to quote completed filenames if they contain any
+     characters in `rl_filename_quote_characters' and
+     `rl_filename_quoting_desired' is set to a non-zero value.
+
+ - Variable: int rl_filename_quoting_desired
+     Non-zero means that the results of the matches are to be quoted
+     using double quotes (or an application-specific quoting mechanism)
+     if the completed filename contains any characters in
+     `rl_filename_quote_chars'.  This is _always_ non-zero on entry,
+     and can only be changed within a completion entry generator
+     function.  The quoting is effected via a call to the function
+     pointed to by `rl_filename_quoting_function'.
+
+ - Variable: int rl_attempted_completion_over
+     If an application-specific completion function assigned to
+     `rl_attempted_completion_function' sets this variable to a non-zero
+     value, Readline will not perform its default filename completion
+     even if the application's completion function returns no matches.
+     It should be set only by an application's completion function.
+
+ - Variable: int rl_completion_type
+     Set to a character describing the type of completion Readline is
+     currently attempting; see the description of
+     `rl_complete_internal()' (*note Completion Functions::) for the
+     list of characters.
+
+ - Variable: int rl_inhibit_completion
+     If this variable is non-zero, completion is inhibited.  The
+     completion character will be inserted as any other bound to
+     `self-insert'.

+The following paragraphs describe the notation used to represent
+keystrokes.
+</P><P>
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+</P><P>
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</P><P>
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+<EM>first</EM>, and then typing <KBD>k</KBD>.
+Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
+</P><P>
+
+The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
+character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
+</P><P>
+
+In addition, several keys have their own names.  Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
+stand for themselves when seen in this text, or in an init file
+(see section <A HREF="rluserman.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
+produce the desired character.
+The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
+some keyboards.

+<!--docid::SEC3::-->
+<P>
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one

+erase character to back up and delete the mistyped character.
+</P><P>
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In

+
+When you add text in the middle of a line, you will notice that characters

+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
+<KBD>C-d</KBD>, and <KBD>DEL</KBD>.  Here are some commands for moving more rapidly

+Notice how <KBD>C-f</KBD> moves forward a character, while <KBD>M-f</KBD> moves
+forward a word.  It is a loose convention that control keystrokes

+<EM>Killing</EM> text means to delete the text from the line, but to save

+<!--docid::SEC7::-->
+<P>
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</P><P>
+
+Readline remembers the last incremental search string.  If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+<!--docid::SEC9::-->
+<P>
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+</P><P>
+
+A great deal of run-time behavior is changeable with the following
+variables.
+</P><P>
+
+<A NAME="IDX4"></A>
+<DL COMPACT>
+
+<DT><CODE>bell-style</CODE>
+<DD><A NAME="IDX5"></A>
+Controls what happens when Readline wants to ring the terminal bell.
+If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
+<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
+If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
+the terminal's bell.
+<P>
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX6"></A>
+The string to insert at the beginning of the line when the
+<CODE>insert-comment</CODE> command is executed.  The default value
+is <CODE>"#"</CODE>.
+<P>
+
+<DT><CODE>completion-ignore-case</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX7"></A>
+The number of possible completions that determines when the user is
+asked whether he wants to see the list of possibilities.  If the
+number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>disable-completion</CODE>
+<DD><A NAME="IDX9"></A>
+If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>editing-mode</CODE>
+<DD><A NAME="IDX10"></A>
+The <CODE>editing-mode</CODE> variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+<P>
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX11"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>expand-tilde</CODE>
+<DD><A NAME="IDX12"></A>
+If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
+attempts word completion.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, the history code attempts to place point at the
+same location on each history line retrived with <CODE>previous-history</CODE>
+or <CODE>next-history</CODE>.
+</P><P>
+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX14"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,
+this variable is set to <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>input-meta</CODE>
+<DD><A NAME="IDX15"></A>
+<A NAME="IDX16"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
+synonym for this variable.
+<P>
+
+<DT><CODE>isearch-terminators</CODE>
+<DD><A NAME="IDX17"></A>
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (see section <A HREF="rluserman.html#SEC8">1.2.5 Searching for Commands in the History</A>).
+If this variable has not been given a value, the characters <KBD>ESC</KBD> and
+<KBD>C-J</KBD> will terminate an incremental search.
+<P>
+
+<DT><CODE>keymap</CODE>
+<DD><A NAME="IDX18"></A>
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable <CODE>keymap</CODE> names are
+<CODE>emacs</CODE>,
+<CODE>emacs-standard</CODE>,
+<CODE>emacs-meta</CODE>,
+<CODE>emacs-ctlx</CODE>,
+<CODE>vi</CODE>,
+<CODE>vi-move</CODE>,
+<CODE>vi-command</CODE>, and
+<CODE>vi-insert</CODE>.
+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
+equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the
+default keymap.
+<P>
+
+<DT><CODE>mark-directories</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
+appended.  The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>mark-modified-lines</CODE>
+<DD><A NAME="IDX19"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
+asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
+This variable is <SAMP>`off'</SAMP> by default.
+<P>
+
+<DT><CODE>mark-symlinked-directories</CODE>
+<DD><A NAME="IDX20"></A>
+If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+<CODE>mark-directories</CODE>).
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX21"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
+names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
+completion, unless the leading <SAMP>`.'</SAMP> is
+supplied by the user in the filename to be completed.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX22"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX23"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
+to display a screenful of possible completions at a time.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>print-completions-horizontally</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>show-all-if-ambiguous</CODE>
+<DD><A NAME="IDX24"></A>
+This alters the default behavior of the completion functions.  If
+set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>visible-stats</CODE>
+<DD><A NAME="IDX25"></A>
+If set to <SAMP>`on'</SAMP>, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is <SAMP>`off'</SAMP>.

+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what

+can be expressed in different ways, depending on what you find most
+comfortable.

+terminal's function keys.  The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc

+Introduction to Line Editing
+============================
+
+   The following paragraphs describe the notation used to represent
+keystrokes.
+
+   The text `C-k' is read as `Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+   The text `M-k' is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key.  The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+   If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>.  Either process is known as "metafying"
+the <k> key.
+
+   The text `M-C-k' is read as `Meta-Control-k' and describes the
+character produced by "metafying" `C-k'.
+
+   In addition, several keys have their own names.  Specifically,
+<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
+when seen in this text, or in an init file (*note Readline Init File::).
+If your keyboard lacks a <LFD> key, typing <C-j> will produce the
+desired character.  The <RET> key may be labeled <Return> or <Enter> on
+some keyboards.

+
+Readline Interaction
+====================
+
+   Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <RET>.  You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.

+
+Readline Bare Essentials
+------------------------
+
+   In order to enter characters into the line, simply type them.  The
+typed character appears where the cursor was, and then the cursor moves
+one space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+   Sometimes you may mistype a character, and not notice the error
+until you have typed several other characters.  In that case, you can
+type `C-b' to move the cursor to the left, and then correct your
+mistake.  Afterwards, you can move the cursor to the right with `C-f'.
+
+   When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are `pushed over' to make room
+for the text that you have inserted.  Likewise, when you delete text
+behind the cursor, characters to the right of the cursor are `pulled
+back' to fill in the blank space created by the removal of the text.  A
+list of the bare essentials for editing the text of an input line
+follows.
+
+`C-b'
+     Move back one character.
+
+`C-f'
+     Move forward one character.
+
+<DEL> or <Backspace>
+     Delete the character to the left of the cursor.
+
+`C-d'
+     Delete the character underneath the cursor.
+
+Printing characters
+     Insert the character into the line at the cursor.
+
+`C-_' or `C-x C-u'
+     Undo the last editing command.  You can undo all the way back to an
+     empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like `C-d', rather than the
+character to the left of the cursor.)

+
+Readline Movement Commands
+--------------------------
+
+   The above table describes the most basic keystrokes that you need in
+order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to `C-b', `C-f', `C-d', and
+<DEL>.  Here are some commands for moving more rapidly about the line.
+
+`C-a'
+     Move to the start of the line.
+
+`C-e'
+     Move to the end of the line.
+
+`M-f'
+     Move forward a word, where a word is composed of letters and
+     digits.
+
+`M-b'
+     Move backward a word.
+
+`C-l'
+     Clear the screen, reprinting the current line at the top.
+
+   Notice how `C-f' moves forward a character, while `M-f' moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.

+
+Readline Killing Commands
+-------------------------
+
+   "Killing" text means to delete the text from the line, but to save
+it away for later use, usually by "yanking" (re-inserting) it back into
+the line.  (`Cut' and `paste' are more recent jargon for `kill' and
+`yank'.)
+
+   If the description for a command says that it `kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+   When you use a kill command, the text is saved in a "kill-ring".
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+   Here is the list of commands for killing text.
+
+`C-k'
+     Kill the text from the current cursor position to the end of the
+     line.
+
+`M-d'
+     Kill from the cursor to the end of the current word, or, if between
+     words, to the end of the next word.  Word boundaries are the same
+     as those used by `M-f'.
+
+`M-<DEL>'
+     Kill from the cursor the start of the current word, or, if between
+     words, to the start of the previous word.  Word boundaries are the
+     same as those used by `M-b'.
+
+`C-w'
+     Kill from the cursor to the previous whitespace.  This is
+     different than `M-<DEL>' because the word boundaries differ.
+
+   Here is how to "yank" the text back into the line.  Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+`C-y'
+     Yank the most recently killed text back into the buffer at the
+     cursor.
+
+`M-y'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `C-y' or `M-y'.
+
+
+File: rluserman.info,  Node: Readline Arguments,  Next: Searching,  Prev: Readline Killing Commands,  Up: Readline Interaction
+
+Readline Arguments
+------------------
+
+   You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type `M-- C-k'.
+
+   The general way to pass numeric arguments to a command is to type
+meta digits before the command.  If the first `digit' typed is a minus
+sign (`-'), then the sign of the argument will be negative.  Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command.  For example, to give
+the `C-d' command an argument of 10, you could type `M-1 0 C-d', which
+will delete the next ten characters on the input line.
+
+
+File: rluserman.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
+
+Searching for Commands in the History
+-------------------------------------
+
+   Readline provides commands for searching through the command history
+for lines containing a specified string.  There are two search modes:
+"incremental" and "non-incremental".
+
+   Incremental searches begin before the user has finished typing the
+search string.  As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far.  An incremental search requires only as many characters
+as needed to find the desired history entry.  To search backward in the
+history for a particular string, type `C-r'.  Typing `C-s' searches
+forward through the history.  The characters present in the value of
+the `isearch-terminators' variable are used to terminate an incremental
+search.  If that variable has not been assigned a value, the <ESC> and
+`C-J' characters will terminate an incremental search.  `C-g' will
+abort an incremental search and restore the original line.  When the
+search is terminated, the history entry containing the search string
+becomes the current line.
+
+   To find other matching entries in the history list, type `C-r' or
+`C-s' as appropriate.  This will search backward or forward in the
+history for the next entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate the
+search and execute that command.  For instance, a <RET> will terminate
+the search and accept the line, thereby executing the command from the
+history list.  A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+   Readline remembers the last incremental search string.  If two
+`C-r's are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+   Non-incremental searches read the entire search string before
+starting to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+Readline Init File
+==================
+
+   Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.  Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory.  The name of this file is taken from the value of the
+environment variable `INPUTRC'.  If that variable is unset, the default
+is `~/.inputrc'.
+
+   When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+   In addition, the `C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+
+* Menu:
+
+* Readline Init File Syntax::	Syntax for the commands in the inputrc file.
+
+* Conditional Init Constructs::	Conditional key bindings in the inputrc file.
+
+* Sample Init File::		An example inputrc file.
+
+
+File: rluserman.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
+
+Readline Init File Syntax
+-------------------------
+
+   There are only a few basic constructs allowed in the Readline init
+file.  Blank lines are ignored.  Lines beginning with a `#' are
+comments.  Lines beginning with a `$' indicate conditional constructs
+(*note Conditional Init Constructs::).  Other lines denote variable
+settings and key bindings.
+
+Variable Settings
+     You can modify the run-time behavior of Readline by altering the
+     values of variables in Readline using the `set' command within the
+     init file.  The syntax is simple:
+
+          set VARIABLE VALUE
+
+     Here, for example, is how to change from the default Emacs-like
+     key binding to use `vi' line editing commands:
+
+          set editing-mode vi
+
+     Variable names and values, where appropriate, are recognized
+     without regard to case.
+
+     A great deal of run-time behavior is changeable with the following
+     variables.
+
+    `bell-style'
+          Controls what happens when Readline wants to ring the
+          terminal bell.  If set to `none', Readline never rings the
+          bell.  If set to `visible', Readline uses a visible bell if
+          one is available.  If set to `audible' (the default),
+          Readline attempts to ring the terminal's bell.
+
+    `comment-begin'
+          The string to insert at the beginning of the line when the
+          `insert-comment' command is executed.  The default value is
+          `"#"'.
+
+    `completion-ignore-case'
+          If set to `on', Readline performs filename matching and
+          completion in a case-insensitive fashion.  The default value
+          is `off'.
+
+    `completion-query-items'
+          The number of possible completions that determines when the
+          user is asked whether he wants to see the list of
+          possibilities.  If the number of possible completions is
+          greater than this value, Readline will ask the user whether
+          or not he wishes to view them; otherwise, they are simply
+          listed.  This variable must be set to an integer value
+          greater than or equal to 0.  The default limit is `100'.
+
+    `convert-meta'
+          If set to `on', Readline will convert characters with the
+          eighth bit set to an ASCII key sequence by stripping the
+          eighth bit and prefixing an <ESC> character, converting them
+          to a meta-prefixed key sequence.  The default value is `on'.
+
+    `disable-completion'
+          If set to `On', Readline will inhibit word completion.
+          Completion  characters will be inserted into the line as if
+          they had been mapped to `self-insert'.  The default is `off'.
+
+    `editing-mode'
+          The `editing-mode' variable controls which default set of key
+          bindings is used.  By default, Readline starts up in Emacs
+          editing mode, where the keystrokes are most similar to Emacs.
+          This variable can be set to either `emacs' or `vi'.
+
+    `enable-keypad'
+          When set to `on', Readline will try to enable the application
+          keypad when it is called.  Some systems need this to enable
+          the arrow keys.  The default is `off'.
+
+    `expand-tilde'
+          If set to `on', tilde expansion is performed when Readline
+          attempts word completion.  The default is `off'.
+
+          If set to `on', the history code attempts to place point at
+          the same location on each history line retrived with
+          `previous-history' or `next-history'.
+
+    `horizontal-scroll-mode'
+          This variable can be set to either `on' or `off'.  Setting it
+          to `on' means that the text of the lines being edited will
+          scroll horizontally on a single screen line when they are
+          longer than the width of the screen, instead of wrapping onto
+          a new screen line.  By default, this variable is set to `off'.
+
+    `input-meta'
+          If set to `on', Readline will enable eight-bit input (it will
+          not clear the eighth bit in the characters it reads),
+          regardless of what the terminal claims it can support.  The
+          default value is `off'.  The name `meta-flag' is a synonym
+          for this variable.
+
+    `isearch-terminators'
+          The string of characters that should terminate an incremental
+          search without subsequently executing the character as a
+          command (*note Searching::).  If this variable has not been
+          given a value, the characters <ESC> and `C-J' will terminate
+          an incremental search.
+
+    `keymap'
+          Sets Readline's idea of the current keymap for key binding
+          commands.  Acceptable `keymap' names are `emacs',
+          `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move',
+          `vi-command', and `vi-insert'.  `vi' is equivalent to
+          `vi-command'; `emacs' is equivalent to `emacs-standard'.  The
+          default value is `emacs'.  The value of the `editing-mode'
+          variable also affects the default keymap.
+
+    `mark-directories'
+          If set to `on', completed directory names have a slash
+          appended.  The default is `on'.
+
+    `mark-modified-lines'
+          This variable, when set to `on', causes Readline to display an
+          asterisk (`*') at the start of history lines which have been
+          modified.  This variable is `off' by default.
+
+    `mark-symlinked-directories'
+          If set to `on', completed names which are symbolic links to
+          directories have a slash appended (subject to the value of
+          `mark-directories').  The default is `off'.
+
+    `match-hidden-files'
+          This variable, when set to `on', causes Readline to match
+          files whose names begin with a `.' (hidden files) when
+          performing filename completion, unless the leading `.' is
+          supplied by the user in the filename to be completed.  This
+          variable is `on' by default.
+
+    `output-meta'
+          If set to `on', Readline will display characters with the
+          eighth bit set directly rather than as a meta-prefixed escape
+          sequence.  The default is `off'.
+
+    `page-completions'
+          If set to `on', Readline uses an internal `more'-like pager
+          to display a screenful of possible completions at a time.
+          This variable is `on' by default.
+
+    `print-completions-horizontally'
+          If set to `on', Readline will display completions with matches
+          sorted horizontally in alphabetical order, rather than down
+          the screen.  The default is `off'.
+
+    `show-all-if-ambiguous'
+          This alters the default behavior of the completion functions.
+          If set to `on', words which have more than one possible
+          completion cause the matches to be listed immediately instead
+          of ringing the bell.  The default value is `off'.
+
+    `visible-stats'
+          If set to `on', a character denoting a file's type is
+          appended to the filename when listing possible completions.
+          The default is `off'.
+
+Key Bindings
+     The syntax for controlling key bindings in the init file is
+     simple.  First you need to find the name of the command that you
+     want to change.  The following sections contain tables of the
+     command name, the default keybinding, if any, and a short
+     description of what the command does.
+
+     Once you know the name of the command, simply place on a line in
+     the init file the name of the key you wish to bind the command to,
+     a colon, and then the name of the command.  The name of the key
+     can be expressed in different ways, depending on what you find most
+     comfortable.
+
+     In addition to command names, readline allows keys to be bound to
+     a string that is inserted when the key is pressed (a MACRO).
+
+    KEYNAME: FUNCTION-NAME or MACRO
+          KEYNAME is the name of a key spelled out in English.  For
+          example:
+               Control-u: universal-argument
+               Meta-Rubout: backward-kill-word
+               Control-o: "> output"
+
+          In the above example, `C-u' is bound to the function
+          `universal-argument', `M-DEL' is bound to the function
+          `backward-kill-word', and `C-o' is bound to run the macro
+          expressed on the right hand side (that is, to insert the text
+          `> output' into the line).
+
+          A number of symbolic character names are recognized while
+          processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+          NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+    "KEYSEQ": FUNCTION-NAME or MACRO
+          KEYSEQ differs from KEYNAME above in that strings denoting an
+          entire key sequence can be specified, by placing the key
+          sequence in double quotes.  Some GNU Emacs style key escapes
+          can be used, as in the following example, but the special
+          character names are not recognized.
+
+               "\C-u": universal-argument
+               "\C-x\C-r": re-read-init-file
+               "\e[11~": "Function Key 1"
+
+          In the above example, `C-u' is again bound to the function
+          `universal-argument' (just as it was in the first example),
+          `C-x C-r' is bound to the function `re-read-init-file', and
+          `<ESC> <[> <1> <1> <~>' is bound to insert the text `Function
+          Key 1'.
+
+     The following GNU Emacs style escape sequences are available when
+     specifying key sequences:
+
+    `\C-'
+          control prefix
+
+    `\M-'
+          meta prefix
+
+    `\e'
+          an escape character
+
+    `\\'
+          backslash
+
+    `\"'
+          <">, a double quotation mark
+
+    `\''
+          <'>, a single quote or apostrophe
+
+     In addition to the GNU Emacs style escape sequences, a second set
+     of backslash escapes is available:
+
+    `\a'
+          alert (bell)
+
+    `\b'
+          backspace
+
+    `\d'
+          delete
+
+    `\f'
+          form feed
+
+    `\n'
+          newline
+
+    `\r'
+          carriage return
+
+    `\t'
+          horizontal tab
+
+    `\v'
+          vertical tab
+
+    `\NNN'
+          the eight-bit character whose value is the octal value NNN
+          (one to three digits)
+
+    `\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+
+     When entering the text of a macro, single or double quotes must be
+     used to indicate a macro definition.  Unquoted text is assumed to
+     be a function name.  In the macro body, the backslash escapes
+     described above are expanded.  Backslash will quote any other
+     character in the macro text, including `"' and `''.  For example,
+     the following binding will make `C-x \' insert a single `\' into
+     the line:
+          "\C-x\\": "\\"

+
+Conditional Init Constructs
+---------------------------
+
+   Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings
+and variable settings to be performed as the result of tests.  There
+are four parser directives used.
+
+`$if'
+     The `$if' construct allows bindings to be made based on the
+     editing mode, the terminal being used, or the application using
+     Readline.  The text of the test extends to the end of the line; no
+     characters are required to isolate it.
+
+    `mode'
+          The `mode=' form of the `$if' directive is used to test
+          whether Readline is in `emacs' or `vi' mode.  This may be
+          used in conjunction with the `set keymap' command, for
+          instance, to set bindings in the `emacs-standard' and
+          `emacs-ctlx' keymaps only if Readline is starting out in
+          `emacs' mode.
+
+    `term'
+          The `term=' form may be used to include terminal-specific key
+          bindings, perhaps to bind the key sequences output by the
+          terminal's function keys.  The word on the right side of the
+          `=' is tested against both the full name of the terminal and
+          the portion of the terminal name before the first `-'.  This
+          allows `sun' to match both `sun' and `sun-cmd', for instance.
+
+    `application'
+          The APPLICATION construct is used to include
+          application-specific settings.  Each program using the
+          Readline library sets the APPLICATION NAME, and you can test
+          for a particular value.  This could be used to bind key
+          sequences to functions useful for a specific program.  For
+          instance, the following command adds a key sequence that
+          quotes the current or previous word in Bash:
+               $if Bash
+               # Quote the current or previous word
+               "\C-xq": "\eb\"\ef\""
+               $endif
+
+`$endif'
+     This command, as seen in the previous example, terminates an `$if'
+     command.
+
+`$else'
+     Commands in this branch of the `$if' directive are executed if the
+     test fails.
+
+`$include'
+     This directive takes a single filename as an argument and reads
+     commands and bindings from that file.  For example, the following
+     directive reads from `/etc/inputrc':
+          $include /etc/inputrc
+

+
+Commands For Manipulating The History
+-------------------------------------
+
+`accept-line (Newline or Return)'
+     Accept the line regardless of where the cursor is.  If this line is
+     non-empty, it may be added to the history list for future recall
+     with `add_history()'.  If this line is a modified history line,
+     the history line is restored to its original state.
+
+`previous-history (C-p)'
+     Move `back' through the history list, fetching the previous
+     command.
+
+`next-history (C-n)'
+     Move `forward' through the history list, fetching the next command.
+
+`beginning-of-history (M-<)'
+     Move to the first line in the history.
+
+`end-of-history (M->)'
+     Move to the end of the input history, i.e., the line currently
+     being entered.
+
+`reverse-search-history (C-r)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary.  This is an incremental search.
+
+`forward-search-history (C-s)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary.  This is an incremental
+     search.
+
+`non-incremental-reverse-search-history (M-p)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`non-incremental-forward-search-history (M-n)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`history-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`history-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`yank-nth-arg (M-C-y)'
+     Insert the first argument to the previous command (usually the
+     second word on the previous line) at point.  With an argument N,
+     insert the Nth word from the previous command (the words in the
+     previous command begin with word 0).  A negative argument inserts
+     the Nth word from the end of the previous command.
+
+`yank-last-arg (M-. or M-_)'
+     Insert last argument to the previous command (the last word of the
+     previous history entry).  With an argument, behave exactly like
+     `yank-nth-arg'.  Successive calls to `yank-last-arg' move back
+     through the history list, inserting the last argument of each line
+     in turn.
+

+File: rluserman.info,  Node: Commands For Text,  Next: Commands For Killing,  Prev: Commands For History,  Up: Bindable Readline Commands
+
+Commands For Changing Text
+--------------------------
+
+`delete-char (C-d)'
+     Delete the character at point.  If point is at the beginning of
+     the line, there are no characters in the line, and the last
+     character typed was not bound to `delete-char', then return EOF.
+
+`backward-delete-char (Rubout)'
+     Delete the character behind the cursor.  A numeric argument means
+     to kill the characters instead of deleting them.
+
+`forward-backward-delete-char ()'
+     Delete the character under the cursor, unless the cursor is at the
+     end of the line, in which case the character behind the cursor is
+     deleted.  By default, this is not bound to a key.
+
+`quoted-insert (C-q or C-v)'
+     Add the next character typed to the line verbatim.  This is how to
+     insert key sequences like `C-q', for example.
+
+`tab-insert (M-<TAB>)'
+     Insert a tab character.
+
+`self-insert (a, b, A, 1, !, ...)'
+     Insert yourself.
+
+`transpose-chars (C-t)'
+     Drag the character before the cursor forward over the character at
+     the cursor, moving the cursor forward as well.  If the insertion
+     point is at the end of the line, then this transposes the last two
+     characters of the line.  Negative arguments have no effect.
+
+`transpose-words (M-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.
+
+`upcase-word (M-u)'
+     Uppercase the current (or following) word.  With a negative
+     argument, uppercase the previous word, but do not move the cursor.
+
+`downcase-word (M-l)'
+     Lowercase the current (or following) word.  With a negative
+     argument, lowercase the previous word, but do not move the cursor.
+
+`capitalize-word (M-c)'
+     Capitalize the current (or following) word.  With a negative
+     argument, capitalize the previous word, but do not move the cursor.
+
+`overwrite-mode ()'
+     Toggle overwrite mode.  With an explicit positive numeric argument,
+     switches to overwrite mode.  With an explicit non-positive numeric
+     argument, switches to insert mode.  This command affects only
+     `emacs' mode; `vi' mode does overwrite differently.  Each call to
+     `readline()' starts in insert mode.
+
+     In overwrite mode, characters bound to `self-insert' replace the
+     text at point rather than pushing the text to the right.
+     Characters bound to `backward-delete-char' replace the character
+     before point with a space.
+
+     By default, this command is unbound.

+
+Killing And Yanking
+-------------------
+
+`kill-line (C-k)'
+     Kill the text from point to the end of the line.
+
+`backward-kill-line (C-x Rubout)'
+     Kill backward to the beginning of the line.
+
+`unix-line-discard (C-u)'
+     Kill backward from the cursor to the beginning of the current line.
+
+`kill-whole-line ()'
+     Kill all characters on the current line, no matter where point is.
+     By default, this is unbound.
+
+`kill-word (M-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as `forward-word'.
+
+`backward-kill-word (M-<DEL>)'
+     Kill the word behind point.  Word boundaries are the same as
+     `backward-word'.
+
+`unix-word-rubout (C-w)'
+     Kill the word behind point, using white space as a word boundary.
+     The killed text is saved on the kill-ring.
+
+`delete-horizontal-space ()'
+     Delete all spaces and tabs around point.  By default, this is
+     unbound.
+
+`kill-region ()'
+     Kill the text in the current region.  By default, this command is
+     unbound.
+
+`copy-region-as-kill ()'
+     Copy the text in the region to the kill buffer, so it can be yanked
+     right away.  By default, this command is unbound.
+
+`copy-backward-word ()'
+     Copy the word before point to the kill buffer.  The word
+     boundaries are the same as `backward-word'.  By default, this
+     command is unbound.
+
+`copy-forward-word ()'
+     Copy the word following point to the kill buffer.  The word
+     boundaries are the same as `forward-word'.  By default, this
+     command is unbound.
+
+`yank (C-y)'
+     Yank the top of the kill ring into the buffer at point.
+
+`yank-pop (M-y)'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `yank' or `yank-pop'.
+

+
+Specifying Numeric Arguments
+----------------------------
+
+`digit-argument (M-0, M-1, ... M--)'
+     Add this digit to the argument already accumulating, or start a new
+     argument.  `M--' starts a negative argument.
+
+`universal-argument ()'
+     This is another way to specify an argument.  If this command is
+     followed by one or more digits, optionally with a leading minus
+     sign, those digits define the argument.  If the command is
+     followed by digits, executing `universal-argument' again ends the
+     numeric argument, but is otherwise ignored.  As a special case, if
+     this command is immediately followed by a character that is
+     neither a digit or minus sign, the argument count for the next
+     command is multiplied by four.  The argument count is initially
+     one, so executing this function the first time makes the argument
+     count four, a second time makes the argument count sixteen, and so
+     on.  By default, this is not bound to a key.
+
+
+File: rluserman.info,  Node: Commands For Completion,  Next: Keyboard Macros,  Prev: Numeric Arguments,  Up: Bindable Readline Commands
+
+Letting Readline Type For You
+-----------------------------
+
+`complete (<TAB>)'
+     Attempt to perform completion on the text before point.  The
+     actual completion performed is application-specific.  The default
+     is filename completion.
+
+`possible-completions (M-?)'
+     List the possible completions of the text before point.
+
+`insert-completions (M-*)'
+     Insert all completions of the text before point that would have
+     been generated by `possible-completions'.
+
+`menu-complete ()'
+     Similar to `complete', but replaces the word to be completed with
+     a single match from the list of possible completions.  Repeated
+     execution of `menu-complete' steps through the list of possible
+     completions, inserting each match in turn.  At the end of the list
+     of completions, the bell is rung (subject to the setting of
+     `bell-style') and the original text is restored.  An argument of N
+     moves N positions forward in the list of matches; a negative
+     argument may be used to move backward through the list.  This
+     command is intended to be bound to <TAB>, but is unbound by
+     default.
+
+`delete-char-or-list ()'
+     Deletes the character under the cursor if not at the beginning or
+     end of the line (like `delete-char').  If at the end of the line,
+     behaves identically to `possible-completions'.  This command is
+     unbound by default.

+
+Keyboard Macros
+---------------
+
+`start-kbd-macro (C-x ()'
+     Begin saving the characters typed into the current keyboard macro.
+
+`end-kbd-macro (C-x ))'
+     Stop saving the characters typed into the current keyboard macro
+     and save the definition.
+
+`call-last-kbd-macro (C-x e)'
+     Re-execute the last keyboard macro defined, by making the
+     characters in the macro appear as if typed at the keyboard.
+
+
+File: rluserman.info,  Node: Miscellaneous Commands,  Prev: Keyboard Macros,  Up: Bindable Readline Commands
+
+Some Miscellaneous Commands
+---------------------------
+
+`re-read-init-file (C-x C-r)'
+     Read in the contents of the INPUTRC file, and incorporate any
+     bindings or variable assignments found there.
+
+`abort (C-g)'
+     Abort the current editing command and ring the terminal's bell
+     (subject to the setting of `bell-style').
+
+`do-uppercase-version (M-a, M-b, M-X, ...)'
+     If the metafied character X is lowercase, run the command that is
+     bound to the corresponding uppercase character.
+
+`prefix-meta (<ESC>)'
+     Metafy the next character typed.  This is for keyboards without a
+     meta key.  Typing `<ESC> f' is equivalent to typing `M-f'.
+
+`undo (C-_ or C-x C-u)'
+     Incremental undo, separately remembered for each line.
+
+`revert-line (M-r)'
+     Undo all changes made to this line.  This is like executing the
+     `undo' command enough times to get back to the beginning.
+
+`tilde-expand (M-~)'
+     Perform tilde expansion on the current word.
+
+`set-mark (C-@)'
+     Set the mark to the point.  If a numeric argument is supplied, the
+     mark is set to that position.
+
+`exchange-point-and-mark (C-x C-x)'
+     Swap the point with the mark.  The current cursor position is set
+     to the saved position, and the old cursor position is saved as the
+     mark.
+
+`character-search (C-])'
+     A character is read and point is moved to the next occurrence of
+     that character.  A negative count searches for previous
+     occurrences.
+
+`character-search-backward (M-C-])'
+     A character is read and point is moved to the previous occurrence
+     of that character.  A negative count searches for subsequent
+     occurrences.
+
+`insert-comment (M-#)'
+     Without a numeric argument, the value of the `comment-begin'
+     variable is inserted at the beginning of the current line.  If a
+     numeric argument is supplied, this command acts as a toggle:  if
+     the characters at the beginning of the line do not match the value
+     of `comment-begin', the value is inserted, otherwise the
+     characters in `comment-begin' are deleted from the beginning of
+     the line.  In either case, the line is accepted as if a newline
+     had been typed.
+
+`dump-functions ()'
+     Print all of the functions and their key bindings to the Readline
+     output stream.  If a numeric argument is supplied, the output is
+     formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+`dump-variables ()'
+     Print all of the settable variables and their values to the
+     Readline output stream.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`dump-macros ()'
+     Print all of the Readline key sequences bound to macros and the
+     strings they output.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`emacs-editing-mode (C-e)'
+     When in `vi' command mode, this causes a switch to `emacs' editing
+     mode.
+
+`vi-editing-mode (M-C-j)'
+     When in `emacs' editing mode, this causes a switch to `vi' editing
+     mode.
+
+
+File: rluserman.info,  Node: Readline vi Mode,  Prev: Bindable Readline Commands,  Up: Command Line Editing
+
+Readline vi Mode
+================
+
+   While the Readline library does not have a full set of `vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline `vi' mode behaves as specified in the POSIX 1003.2
+standard.
+
+   In order to switch interactively between `emacs' and `vi' editing
+modes, use the command `M-C-j' (bound to emacs-editing-mode when in
+`vi' mode and to vi-editing-mode in `emacs' mode).  The Readline
+default is `emacs' mode.
+
+   When you enter a line in `vi' mode, you are already placed in
+`insertion' mode, as if you had typed an `i'.  Pressing <ESC> switches
+you into `command' mode, where you can edit the text of the line with
+the standard `vi' movement keys, move to previous history lines with
+`k' and subsequent lines with `j', and so forth.

-This document details the changes between this version, readline-2.2.1,
-and the previous version, readline-2.2.
-
-1.  Changes to Readline
-
-a.  The `make install' target was corrected so that it did not move the
-    newly-installed libreadline.a to libhistory.old
-
-b.  The `make install' target for the documentation will now install the
-    info files from the source directory if they do not appear in the
-    build directory, since they are shipped in the readline tar file.
-
-c.  Fixed a problem with redisplay that showed up when the prompt string was
-    longer than the screen width and the prompt contained invisible characters.
-
-d.  Fixed a problem with the paren matching code -- the blink was far too
-    short (it's specified in microseconds, not milliseconds, Chet!).
-
-------------------------------------------------------------------------------
-This document details the changes between this version, readline-2.2,
-and the previous version, readline-2.1.
-
-1.  Changes to Readline
-
-a.  Added a missing `extern' to a declaration in readline.h that kept
-    readline from compiling cleanly on some systems.
-
-b.  The history file is now opened with mode 0600 when it is written for
-    better security.
-
-c.  Changes were made to the SIGWINCH handling code so that prompt redisplay
-    is done better.
-
-d.  ^G now interrupts incremental searches correctly.
-
-e.  A bug that caused a core dump when the set of characters to be quoted
-    when completing words was empty was fixed.
-
-f.  Fixed a problem in the readline test program rltest.c that caused a core
-    dump.
-
-g.  The code that handles parser directives in inputrc files now displays
-    more error messages.
-
-h.  The history expansion code was fixed so that the appearance of the
-    history comment character at the beginning of a word inhibits history
-    expansion for that word and the rest of the input line.
-
-i.  The code that prints completion listings now behaves better if one or
-    more of the filenames contains non-printable characters.
-
-j.  The time delay when showing matching parentheses is now 0.5 seconds.
-
-
-2.  New Features in Readline
-
-a.  There is now an option for `iterative' yank-last-arg handline, so a user
-    can keep entering `M-.', yanking the last argument of successive history
-    lines.
-
-b.  New variable, `print-completions-horizontally', which causes completion
-    matches to be displayed across the screen (like `ls -x') rather than up
-    and down the screen (like `ls').
-
-c.  New variable, `completion-ignore-case', which causes filename completion
-    and matching to be performed case-insensitively.
-
-d.  There is a new bindable command, `magic-space', which causes history
-    expansion to be performed on the current readline buffer and a space to
-    be inserted into the result.
-
-e.  There is a new bindable command, `menu-complete', which enables tcsh-like
-    menu completion (successive executions of menu-complete insert a single
-    completion match, cycling through the list of possible completions).
-
-f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
-    systems, to insert the text from the Win32 clipboard into the editing
-    buffer.
-
-g.  The key sequence translation code now understands printf-style backslash
-    escape sequences, including \NNN octal escapes.  These escape sequences
-    may be used in key sequence definitions or macro values.
-
-h.  An `$include' inputrc file parser directive has been added.

-
-	* readline.c: rl_search_history (): Correctly handle case of an

-
-Tue Mar 20 05:38:55 1990  Brian Fox  (bfox at gnuwest.fsf.org)

-Sun Sep  3 08:57:40 1989  Brian Fox  (bfox at aurel)
-
-	* readline.c: start_insert ().  Uses multiple
-	  insertion call in cases where that makes sense.
-
-	  rl_insert ().  Read type-ahead buffer for additional

-	  with an argument much more efficient.
-
-Tue Aug  8 18:13:57 1989  Brian Fox  (bfox at aurel)

-	 tty, or if the tty doesn't have one, defaults to C-d.
-
-	* readline.c: Added support for event driven programs.
-	  rl_event_hook is the address of a function you want called
-	  while Readline is waiting for input.
-
-	* readline.c: Cleanup time.  Functions without type declarations
-	  do not use return with a value.

-	  of reading the line.
-
-Tue Jul 11 06:25:01 1989  Brian Fox  (bfox at aurel)
-
-	* readline.c: new variable rl_tilde_expander.
-	  If non-null, this contains the address of a function to call if
-	  the standard meaning for expanding a tilde fails.  The function is
-	  called with the text sans tilde (as in "foo"), and returns a
-	  malloc()'ed string which is the expansion, or a NULL pointer if
-	  there is no expansion. 
-
-	* readline.h - new file chardefs.h
-	  Separates things that only readline.c needs from the standard
-	  header file publishing interesting things about readline.
-
-	* readline.c:
-	  readline_default_bindings () now looks at terminal chararacters
-	  and binds those as well.
-
-Wed Jun 28 20:20:51 1989  Brian Fox  (bfox at aurel)
-
-	* Made readline and history into independent libraries.

-Introduction
-============
-
-This is the Gnu Readline library, version 2.2
-
-The Readline library provides a set of functions for use by applications
-that allow users to edit command lines as they are typed in.  Both
-Emacs and vi editing modes are available.  The Readline library includes
-additional functions to maintain a list of previously-entered command
-lines, to recall and perhaps reedit those lines, and perform csh-like
-history expansion on previous commands.
-
-The history facilites are also placed into a separate library, the
-History library, as part of the build process.  The History library
-may be used without Readline in applications which desire its
-capabilities.
-
-The Readline library is free software, distributed under the terms of
-the GNU Public License, version 2.  For more information, see the file
-COPYING.
-
-To build the library, try typing `./configure', then `make'.  The
-configuration process is automated, so no further intervention should
-be necessary.  Readline builds with `gcc' by default if it is
-available.  If you want to use `cc' instead, type
-
-        CC=cc ./configure
-
-if you are using a Bourne-style shell.  If you are not, the following
-may work:
-
-        env CC=cc ./configure
-
-Read the file INSTALL in this directory for more information about how
-to customize and control the build process.
-
-The file rlconf.h contains defines that enable and disable certain
-Readline features.
-
-Examples
-========
-
-There are several example programs that use Readline features in the
-examples directory.  The `rl' program is of particular interest.  It
-is a command-line interface to Readline, suitable for use in shell
-scripts in place of `read'.
-
-Shared Libraries
-================
-
-There is skeletal support for building shared versions of the
-Readline and History libraries.
-
-Typing `make shared' will cause shared versions of the Readline and
-History libraries to be built on SunOS 4.1.x.  For versions of Unix
-other than SunOS, you will have to make some changes to Makefile.in.
-The relevant variables are:
-
-PICFLAG		Options to give to the compiler to produce position-independent
-		code.  The value `-fpic' works for most versions of gcc.
-SHLIB_OPTS	Options to give to the linker to produce a shared library.
-		The value `-assert pure-text -ldl' works on SunOS 4.1.x.
-		The value `-Bshareable' works for some versions of GNU ld.
-
-MAJOR		The major version number of the shared library.  You should
-		not need to change this.
-MINOR		The minor version number of the shared library.  Some systems,
-		such as SVR4 and its descendents (e.g., Solaris, Unixware),
-		do not use minor version numbers.  For those systems, this
-		variable should be left unset.
-
-LD		The linker.  The value of `ld' is correct for SunOS 4.1.x.
-		You may need to change it to `gcc'; make sure to change
-		SHLIB_OPTS if you do so.
-
-Once you have edited Makefile.in, type `make Makefile' to rebuild the
-Makefile, then `make shared' to build the shared libraries.
-
-Documentation
-=============
-
-The documentation for the Readline and History libraries appears in the
-`doc' subdirectory.  There are two texinfo files and a Unix-style manual
-page describing the programming facilities available in the Readline
-library.  The texinfo files include both user and programmer's manuals.
-
-Reporting Bugs
-==============
-
-Bug reports for Readline should be sent to:
-
-        bug-readline@gnu.org
-
-When reporting a bug, please include the following information:
-
-        * the version number and release status of Readline (e.g., 2.2-release)
-        * the machine and OS that it is running on
-        * a list of the compilation flags or the contents of `config.h', if
-          appropriate
-        * a description of the bug
-        * a recipe for recreating the bug reliably
-        * a fix for the bug if you have one!
-
-If you would like to contact the Readline maintainer directly, send mail
-to bash-maintainers@gnu.org.
-
-Since Readline is developed along with bash, the bug-bash@gnu.org mailing
-list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
-Readline bug reports and fixes.

-@node Using History Interactively
-@appendix Using History Interactively
-
-This chapter describes how to use the GNU History Library interactively,
-from a user's standpoint.
-
-@menu
-* History Interaction::		What it feels like using History as a user.
-@end menu
-
-@node History Interaction
-@section History Interaction
-@cindex expansion
-
-The History library provides a history expansion feature similar
-to the history expansion in @code{csh}.  The following text describes the 
-syntax you use to manipulate history information.
-
-History expansion takes two parts.  In the first part, determine
-which line from the previous history will be used for substitution.
-This line is called the @dfn{event}.
-In the second part, select portions of that line for inclusion into the
-current line.  These portions are called @dfn{words}.  
-@value{GDBN} breaks the line into words in the same 
-way that the Bash shell does, so that several English (or Unix) words
-surrounded by quotes are considered one word.
-
-@menu
-* Event Designators::	How to specify which history line to use.
-* Word Designators::	Specifying which words are of interest.
-* Modifiers::		Modifying the results of susbstitution.
-@end menu
-
-@node Event Designators
-@subsection Event Designators
-@cindex event designators
-
-An @dfn{event designator} is a reference to a command line entry in the
-history list.
-
-@table @asis
-
-@item @code{!}
-Start a history subsititution, except when followed by a space, tab, or
-the end of the line... @key{=} or @key{(}.
-
-@item @code{!!}
-Refer to the previous command.  This is a synonym for @code{!-1}.
-
-@item @code{!n}
-Refer to command line @var{n}.
-
-@item @code{!-n}
-Refer to the command line @var{n} lines back.
-
-@item @code{!string}
-Refer to the most recent command starting with @var{string}.
-
-@item @code{!?string}[@code{?}]
-Refer to the most recent command containing @var{string}.
-
-@end table
-
-@node Word Designators
-@subsection Word Designators
-
-A @key{:} separates the event designator from the @dfn{word designator}.  
-It can be omitted if the word designator begins with a @key{^}, @key{$},
-@key{*} or @key{%}.  Words are numbered from the beginning of the line,
-with the first word being denoted by a 0 (zero).
-
-@table @code
-
-@item 0 (zero)
-The zero'th word.  For many applications, this is the command word.
-
-@item n
-The @var{n}'th word.
-
-@item ^
-The first argument.  that is, word 1.
-
-@item $
-The last argument.
-
-@item %
-The word matched by the most recent @code{?string?} search.
-
-@item x-y
-A range of words; @code{-@var{y}} Abbreviates @code{0-@var{y}}.
-
-@item *
-All of the words, excepting the zero'th.  This is a synonym for @code{1-$}.
-It is not an error to use @key{*} if there is just one word in the event.
-The empty string is returned in that case.
-
-@end table
-
-@node Modifiers
-@subsection Modifiers
-
-After the optional word designator, you can add a sequence of one or more
-of the following @dfn{modifiers}, each preceded by a @key{:}.
-
-@table @code
-
-@item #
-The entire command line typed so far.  This means the current command,
-not the previous command.
-@c
-@c  FIXME:  If it doesn't belong here, let's put it where it does. 
-@c
-@c  so it technically isn't a word designator and doesn't belong in 
-@c  this section.
-
-@item h
-Remove a trailing pathname component, leaving only the head.
-
-@item r
-Remove a trailing suffix of the form @samp{.}@var{suffix}, leaving the basename.
-
-@item e
-Remove all but the suffix.
-
-@item t
-Remove all leading  pathname  components, leaving the tail.
-
-@item p
-Print the new command but do not execute it.

-@chapter Programming with GNU Readline
-
-This chapter describes the interface between the GNU Readline Library and
-other programs.  If you are a programmer, and you wish to include the
-features found in GNU Readline
-such as completion, line editing, and interactive history manipulation
-in your own programs, this section is for you.

-
-@node Basic Behavior
-@section Basic Behavior
-
-Many programs provide a command line interface, such as @code{mail},
-@code{ftp}, and @code{sh}.  For such programs, the default behaviour of
-Readline is sufficient.  This section describes how to use Readline in
-the simplest way possible, perhaps to replace calls in your code to
-@code{gets()} or @code{fgets ()}.
-
-@findex readline
-@cindex readline, function
-The function @code{readline ()} prints a prompt and then reads and returns
-a single line of text from the user.  The line @code{readline}
-returns is allocated with @code{malloc ()}; you should @code{free ()}
-the line when you are done with it.  The declaration for @code{readline}
-in ANSI C is
-
-@example
-@code{char *readline (char *@var{prompt});}
-@end example
-
-@noindent
-So, one might say
-@example
-@code{char *line = readline ("Enter a line: ");}
-@end example
-@noindent
-in order to read a line of text from the user.
-The line returned has the final newline removed, so only the
-text remains.
-
-If @code{readline} encounters an @code{EOF} while reading the line, and the
-line is empty at that point, then @code{(char *)NULL} is returned.
-Otherwise, the line is ended just as if a newline had been typed.
-
-If you want the user to be able to get at the line later, (with
-@key{C-p} for example), you must call @code{add_history ()} to save the
-line away in a @dfn{history} list of such lines.
-
-@example
-@code{add_history (line)};
-@end example
-
-@noindent
-For full details on the GNU History Library, see the associated manual.
-
-It is preferable to avoid saving empty lines on the history list, since
-users rarely have a burning need to reuse a blank line.  Here is
-a function which usefully replaces the standard @code{gets ()} library
-function, and has the advantage of no static buffer to overflow:
-
-@example
-/* A static variable for holding the line. */
-static char *line_read = (char *)NULL;
-
-/* Read a string, and return a pointer to it.  Returns NULL on EOF. */
-char *
-rl_gets ()
-@{
-  /* If the buffer has already been allocated, return the memory
-     to the free pool. */
-  if (line_read)
-    @{
-      free (line_read);
-      line_read = (char *)NULL;
-    @}
-
-  /* Get a line from the user. */
-  line_read = readline ("");
-
-  /* If the line has any text in it, save it on the history. */
-  if (line_read && *line_read)
-    add_history (line_read);
-
-  return (line_read);
-@}
-@end example
-
-This function gives the user the default behaviour of @key{TAB}
-completion: completion on file names.  If you do not want Readline to
-complete on filenames, you can change the binding of the @key{TAB} key
-with @code{rl_bind_key ()}.
-
-@example
-@code{int rl_bind_key (int @var{key}, int (*@var{function})());}
-@end example
-
-@code{rl_bind_key ()} takes two arguments: @var{key} is the character that
-you want to bind, and @var{function} is the address of the function to
-call when @var{key} is pressed.  Binding @key{TAB} to @code{rl_insert ()}
-makes @key{TAB} insert itself.
-@code{rl_bind_key ()} returns non-zero if @var{key} is not a valid
-ASCII character code (between 0 and 255).
-
-Thus, to disable the default @key{TAB} behavior, the following suffices:
-@example
-@code{rl_bind_key ('\t', rl_insert);}
-@end example
-
-This code should be executed once at the start of your program; you
-might write a function called @code{initialize_readline ()} which
-performs this and other desired initializations, such as installing
-custom completers (@pxref{Custom Completers}).
-
-@node Custom Functions
-@section Custom Functions
-
-Readline provides many functions for manipulating the text of
-the line, but it isn't possible to anticipate the needs of all
-programs.  This section describes the various functions and variables
-defined within the Readline library which allow a user program to add
-customized functionality to Readline.
-
-@menu
-* The Function Type::	C declarations to make code readable.
-* Function Writing::	Variables and calling conventions.
-@end menu
-
-@node The Function Type
-@subsection The Function Type
-
-For readabilty, we declare a new type of object, called
-@dfn{Function}.  A @code{Function} is a C function which
-returns an @code{int}.  The type declaration for @code{Function} is:
-
-@noindent
-@code{typedef int Function ();}
-
-The reason for declaring this new type is to make it easier to write
-code describing pointers to C functions.  Let us say we had a variable
-called @var{func} which was a pointer to a function.  Instead of the
-classic C declaration
-
-@code{int (*)()func;}
-
-@noindent
-we may write
-
-@code{Function *func;}
-
-@noindent
-Similarly, there are
-
-@example
-typedef void VFunction ();
-typedef char *CPFunction (); @r{and}
-typedef char **CPPFunction ();
-@end example
-
-@noindent
-for functions returning no value, @code{pointer to char}, and
-@code{pointer to pointer to char}, respectively.
-
-@node Function Writing
-@subsection Writing a New Function
-
-In order to write new functions for Readline, you need to know the
-calling conventions for keyboard-invoked functions, and the names of the
-variables that describe the current state of the line read so far.
-
-The calling sequence for a command @code{foo} looks like
-
-@example
-@code{foo (int count, int key)}
-@end example
-
-@noindent
-where @var{count} is the numeric argument (or 1 if defaulted) and
-@var{key} is the key that invoked this function.
-
-It is completely up to the function as to what should be done with the
-numeric argument.  Some functions use it as a repeat count, some
-as a flag, and others to choose alternate behavior (refreshing the current
-line as opposed to refreshing the screen, for example).  Some choose to
-ignore it.  In general, if a
-function uses the numeric argument as a repeat count, it should be able
-to do something useful with both negative and positive arguments.
-At the very least, it should be aware that it can be passed a
-negative argument.
-
-@node Readline Variables
-@section Readline Variables
-
-These variables are available to function writers.
-
-@deftypevar {char *} rl_line_buffer
-This is the line gathered so far.  You are welcome to modify the
-contents of the line, but see @ref{Allowing Undoing}.
-@end deftypevar
-
-@deftypevar int rl_point
-The offset of the current cursor position in @code{rl_line_buffer}
-(the @emph{point}).
-@end deftypevar
-
-@deftypevar int rl_end
-The number of characters present in @code{rl_line_buffer}.  When
-@code{rl_point} is at the end of the line, @code{rl_point} and
-@code{rl_end} are equal.
-@end deftypevar
-
-@deftypevar int rl_mark
-The mark (saved position) in the current line.  If set, the mark
-and point define a @emph{region}.
-@end deftypevar

-Setting this to a non-zero value causes Readline to return the current
-line immediately.
-@end deftypevar
-
-@deftypevar int rl_pending_input
-Setting this to a value makes it the next keystroke read.  This is a
-way to stuff a single character into the input stream.
-@end deftypevar

-If non-zero, this is the address of a function to call just
-before @code{readline} prints the first prompt.
-@end deftypevar
-
-@deftypevar {Function *} rl_event_hook
-If non-zero, this is the address of a function to call periodically
-when readline is waiting for terminal input.
-@end deftypevar
-
-@deftypevar {Function *} rl_getc_function
-If non-zero, @code{readline} will call indirectly through this pointer

-
-@node Function Naming
-@subsection Naming a Function
-
-The user can dynamically change the bindings of keys while using
-Readline.  This is done by representing the function with a descriptive
-name.  The user is able to type the descriptive name when referring to
-the function.  Thus, in an init file, one might find
-
-@example
-Meta-Rubout:	backward-kill-word
-@end example
-
-This binds the keystroke @key{Meta-Rubout} to the function
-@emph{descriptively} named @code{backward-kill-word}.  You, as the
-programmer, should bind the functions you write to descriptive names as
-well.  Readline provides a function for doing that:
-
-@deftypefun int rl_add_defun (char *name, Function *function, int key)
-Add @var{name} to the list of named functions.  Make @var{function} be
-the function that gets called.  If @var{key} is not -1, then bind it to
-@var{function} using @code{rl_bind_key ()}.
-@end deftypefun
-
-Using this function alone is sufficient for most applications.  It is
-the recommended way to add a few functions to the default functions that
-Readline has built in.  If you need to do something other
-than adding a function to Readline, you may need to use the
-underlying functions described below.
-
-@node Keymaps
-@subsection Selecting a Keymap
-
-Key bindings take place on a @dfn{keymap}.  The keymap is the
-association between the keys that the user types and the functions that
-get run.  You can make your own keymaps, copy existing keymaps, and tell
-Readline which keymap to use.
-
-@deftypefun Keymap rl_make_bare_keymap ()
-Returns a new, empty keymap.  The space for the keymap is allocated with
-@code{malloc ()}; you should @code{free ()} it when you are done.
-@end deftypefun
-
-@deftypefun Keymap rl_copy_keymap (Keymap map)
-Return a new keymap which is a copy of @var{map}.
-@end deftypefun
-
-@deftypefun Keymap rl_make_keymap ()
-Return a new keymap with the printing characters bound to rl_insert,
-the lowercase Meta characters bound to run their equivalents, and
-the Meta digits bound to produce numeric arguments.
-@end deftypefun
-
-@deftypefun void rl_discard_keymap (Keymap keymap)
-Free the storage associated with @var{keymap}.
-@end deftypefun
-
-Readline has several internal keymaps.  These functions allow you to
-change which keymap is active.
-
-@deftypefun Keymap rl_get_keymap ()
-Returns the currently active keymap.
-@end deftypefun
-
-@deftypefun void rl_set_keymap (Keymap keymap)
-Makes @var{keymap} the currently active keymap.
-@end deftypefun
-
-@deftypefun Keymap rl_get_keymap_by_name (char *name)
-Return the keymap matching @var{name}.  @var{name} is one which would
-be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
-@end deftypefun
-
-@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
-Return the name matching @var{keymap}.  @var{name} is one which would
-be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
-@end deftypefun
-
-@node Binding Keys
-@subsection Binding Keys
-
-You associate keys with functions through the keymap.  Readline has
-several internal keymaps: @code{emacs_standard_keymap},
-@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
-@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
-@code{emacs_standard_keymap} is the default, and the examples in
-this manual assume that.
-
-These functions manage key bindings.
-
-@deftypefun int rl_bind_key (int key, Function *function)
-Binds @var{key} to @var{function} in the currently active keymap.
-Returns non-zero in the case of an invalid @var{key}.
-@end deftypefun
-
-@deftypefun int rl_bind_key_in_map (int key, Function *function, Keymap map)
-Bind @var{key} to @var{function} in @var{map}.  Returns non-zero in the case
-of an invalid @var{key}.
-@end deftypefun
-
-@deftypefun int rl_unbind_key (int key)
-Bind @var{key} to the null function in the currently active keymap.
-Returns non-zero in case of error.
-@end deftypefun
-
-@deftypefun int rl_unbind_key_in_map (int key, Keymap map)
-Bind @var{key} to the null function in @var{map}.
-Returns non-zero in case of error.
-@end deftypefun
-
-@deftypefun int rl_unbind_function_in_map (Function *function, Keymap map)
-Unbind all keys that execute @var{function} in @var{map}.
-@end deftypefun
-
-@deftypefun int rl_unbind_command_in_map (char *command, Keymap map)
-Unbind all keys that are bound to @var{command} in @var{map}.
-@end deftypefun
-
-@deftypefun int rl_generic_bind (int type, char *keyseq, char *data, Keymap map)
-Bind the key sequence represented by the string @var{keyseq} to the arbitrary
-pointer @var{data}.  @var{type} says what kind of data is pointed to by
-@var{data}; this can be a function (@code{ISFUNC}), a macro
-(@code{ISMACR}), or a keymap (@code{ISKMAP}).  This makes new keymaps as
-necessary.  The initial keymap in which to do bindings is @var{map}.
-@end deftypefun
-
-@deftypefun int rl_parse_and_bind (char *line)
-Parse @var{line} as if it had been read from the @code{inputrc} file and
-perform any key bindings and variable assignments found
-(@pxref{Readline Init File}).
-@end deftypefun
-
-@deftypefun int rl_read_init_file (char *filename)
-Read keybindings and variable assignments from @var{filename}
-(@pxref{Readline Init File}).
-@end deftypefun
-
-@node Associating Function Names and Bindings
-@subsection Associating Function Names and Bindings
-
-These functions allow you to find out what keys invoke named functions
-and the functions invoked by a particular key sequence.

-@deftypefun {Function *} rl_named_function (char *name)
-Return the function with name @var{name}.
-@end deftypefun
-
-@deftypefun {Function *} rl_function_of_keyseq (char *keyseq, Keymap map, int *type)
-Return the function invoked by @var{keyseq} in keymap @var{map}.
-If @var{map} is NULL, the current keymap is used.  If @var{type} is
-not NULL, the type of the object is returned in it (one of @code{ISFUNC},
-@code{ISKMAP}, or @code{ISMACR}).
-@end deftypefun
-
-@deftypefun {char **} rl_invoking_keyseqs (Function *function)
-Return an array of strings representing the key sequences used to

-@deftypefun {char **} rl_invoking_keyseqs_in_map (Function *function, Keymap map)
-Return an array of strings representing the key sequences used to

-@end deftypefun
-
-@deftypefun void rl_function_dumper (int readable)
-Print the readline function names and the key sequences currently
-bound to them to @code{rl_outstream}.  If @var{readable} is non-zero,
-the list is formatted in such a way that it can be made part of an
-@code{inputrc} file and re-read.
-@end deftypefun
-
-@deftypefun void rl_list_funmap_names ()
-Print the names of all bindable Readline functions to @code{rl_outstream}.
-@end deftypefun
-
-@node Allowing Undoing
-@subsection Allowing Undoing
-
-Supporting the undo command is a painless thing, and makes your
-functions much more useful.  It is certainly easy to try
-something if you know you can undo it.  I could use an undo function for
-the stock market.
-
-If your function simply inserts text once, or deletes text once, and
-uses @code{rl_insert_text ()} or @code{rl_delete_text ()} to do it, then
-undoing is already done for you automatically.
-
-If you do multiple insertions or multiple deletions, or any combination
-of these operations, you should group them together into one operation.
-This is done with @code{rl_begin_undo_group ()} and
-@code{rl_end_undo_group ()}.
-
-The types of events that can be undone are:
-
-@example
-enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
-@end example
-
-Notice that @code{UNDO_DELETE} means to insert some text, and
-@code{UNDO_INSERT} means to delete some text.  That is, the undo code
-tells undo what to undo, not how to undo it.  @code{UNDO_BEGIN} and
-@code{UNDO_END} are tags added by @code{rl_begin_undo_group ()} and
-@code{rl_end_undo_group ()}.
-
-@deftypefun int rl_begin_undo_group ()
-Begins saving undo information in a group construct.  The undo
-information usually comes from calls to @code{rl_insert_text ()} and
-@code{rl_delete_text ()}, but could be the result of calls to
-@code{rl_add_undo ()}.
-@end deftypefun
-
-@deftypefun int rl_end_undo_group ()
-Closes the current undo group started with @code{rl_begin_undo_group
-()}.  There should be one call to @code{rl_end_undo_group ()}
-for each call to @code{rl_begin_undo_group ()}.
-@end deftypefun
-
-@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
-Remember how to undo an event (according to @var{what}).  The affected
-text runs from @var{start} to @var{end}, and encompasses @var{text}.
-@end deftypefun
-
-@deftypefun void free_undo_list ()
-Free the existing undo list.
-@end deftypefun
-
-@deftypefun int rl_do_undo ()
-Undo the first thing on the undo list.  Returns @code{0} if there was
-nothing to undo, non-zero if something was undone.
-@end deftypefun
-
-Finally, if you neither insert nor delete text, but directly modify the
-existing text (e.g., change its case), call @code{rl_modifying ()}
-once, just before you modify the text.  You must supply the indices of
-the text range that you are going to modify.
-
-@deftypefun int rl_modifying (int start, int end)
-Tell Readline to save the text between @var{start} and @var{end} as a
-single undo unit.  It is assumed that you will subsequently modify
-that text.

-@node Alternate Interface
-@subsection Alternate Interface
-
-An alternate interface is available to plain @code{readline()}.  Some
-applications need to interleave keyboard I/O with file, device, or
-window system I/O, typically by using a main loop to @code{select()}
-on various file descriptors.  To accomodate this need, readline can
-also be invoked as a `callback' function from an event loop.  There
-are functions available to make this easy.
-
-@deftypefun void rl_callback_handler_install (char *prompt, Vfunction *lhandler)
-Set up the terminal for readline I/O and display the initial
-expanded value of @var{prompt}.  Save the value of @var{lhandler} to
-use as a callback when a complete line of input has been entered.
-@end deftypefun
-
-@deftypefun void rl_callback_read_char ()
-Whenever an application determines that keyboard input is available, it
-should call @code{rl_callback_read_char()}, which will read the next
-character from the current input source.  If that character completes the
-line, @code{rl_callback_read_char} will invoke the @var{lhandler}
-function saved by @code{rl_callback_handler_install} to process the
-line.  @code{EOF} is  indicated by calling @var{lhandler} with a
-@code{NULL} line.
-@end deftypefun
-
-@deftypefun void rl_callback_handler_remove ()
-Restore the terminal to its initial state and remove the line handler.
-This may be called from within a callback as well as independently.
-@end deftypefun
-
-@subsection An Example
-
-Here is a function which changes lowercase characters to their uppercase
-equivalents, and uppercase characters to lowercase.  If
-this function was bound to @samp{M-c}, then typing @samp{M-c} would
-change the case of the character under point.  Typing @samp{M-1 0 M-c}
-would change the case of the following 10 characters, leaving the cursor on
-the last character changed.

-@node How Completing Works
-@subsection How Completing Works
-
-In order to complete some text, the full list of possible completions
-must be available.  That is, it is not possible to accurately
-expand a partial word without knowing all of the possible words
-which make sense in that context.  The Readline library provides
-the user interface to completion, and two of the most common
-completion functions:  filename and username.  For completing other types
-of text, you must write your own completion function.  This section
-describes exactly what such functions must do, and provides an example.
-
-There are three major functions used to perform completion:
-
-@enumerate
-@item
-The user-interface function @code{rl_complete ()}.  This function is
-called with the same arguments as other Readline
-functions intended for interactive use:  @var{count} and
-@var{invoking_key}.  It isolates the word to be completed and calls
-@code{completion_matches ()} to generate a list of possible completions.
-It then either lists the possible completions, inserts the possible
-completions, or actually performs the
-completion, depending on which behavior is desired.
-
-@item
-The internal function @code{completion_matches ()} uses your
-@dfn{generator} function to generate the list of possible matches, and
-then returns the array of these matches.  You should place the address
-of your generator function in @code{rl_completion_entry_function}.
-
-@item
-The generator function is called repeatedly from
-@code{completion_matches ()}, returning a string each time.  The
-arguments to the generator function are @var{text} and @var{state}.
-@var{text} is the partial word to be completed.  @var{state} is zero the
-first time the function is called, allowing the generator to perform
-any necessary initialization, and a positive non-zero integer for
-each subsequent call.  When the generator function returns
-@code{(char *)NULL} this signals @code{completion_matches ()} that there are
-no more possibilities left.  Usually the generator function computes the
-list of possible completions when @var{state} is zero, and returns them
-one at a time on subsequent calls.  Each string the generator function
-returns as a match must be allocated with @code{malloc()}; Readline
-frees the strings when it has finished with them.
-
-@end enumerate
-
-@deftypefun int rl_complete (int ignore, int invoking_key)
-Complete the word at or before point.  You have supplied the function
-that does the initial simple matching selection algorithm (see
-@code{completion_matches ()}).  The default is to do filename completion.
-@end deftypefun
-
-@deftypevar {Function *} rl_completion_entry_function
-This is a pointer to the generator function for @code{completion_matches
-()}.  If the value of @code{rl_completion_entry_function} is
-@code{(Function *)NULL} then the default filename generator function,
-@code{filename_completion_function ()}, is used.
-@end deftypevar
-
-@node Completion Functions
-@subsection Completion Functions
-
-Here is the complete list of callable completion functions present in
-Readline.
-
-@deftypefun int rl_complete_internal (int what_to_do)
-Complete the word at or before point.  @var{what_to_do} says what to do
-with the completion.  A value of @samp{?} means list the possible
-completions.  @samp{TAB} means do standard completion.  @samp{*} means
-insert all of the possible completions.  @samp{!} means to display
-all of the possible completions, if there is more than one, as well as
-performing partial completion.
-@end deftypefun
-
-@deftypefun int rl_complete (int ignore, int invoking_key)
-Complete the word at or before point.  You have supplied the function
-that does the initial simple matching selection algorithm (see
-@code{completion_matches ()} and @code{rl_completion_entry_function}).
-The default is to do filename
-completion.  This calls @code{rl_complete_internal ()} with an
-argument depending on @var{invoking_key}.
-@end deftypefun
-
-@deftypefun int rl_possible_completions (int count, int invoking_key))
-List the possible completions.  See description of @code{rl_complete
-()}.  This calls @code{rl_complete_internal ()} with an argument of
-@samp{?}.
-@end deftypefun
-
-@deftypefun int rl_insert_completions (int count, int invoking_key))
-Insert the list of possible completions into the line, deleting the
-partially-completed word.  See description of @code{rl_complete ()}.
-This calls @code{rl_complete_internal ()} with an argument of @samp{*}.
-@end deftypefun
-
-@deftypefun {char **} completion_matches (char *text, CPFunction *entry_func)
-Returns an array of @code{(char *)} which is a list of completions for
-@var{text}.  If there are no completions, returns @code{(char **)NULL}.
-The first entry in the returned array is the substitution for @var{text}.
-The remaining entries are the possible completions.  The array is
-terminated with a @code{NULL} pointer.
-
-@var{entry_func} is a function of two args, and returns a
-@code{(char *)}.  The first argument is @var{text}.  The second is a
-state argument; it is zero on the first call, and non-zero on subsequent
-calls.  @var{entry_func} returns a @code{NULL}  pointer to the caller
-when there are no more matches.
-@end deftypefun
-
-@deftypefun {char *} filename_completion_function (char *text, int state)
-A generator function for filename completion in the general case.  Note
-that completion in Bash is a little different because of all
-the pathnames that must be followed when looking up completions for a
-command.  The Bash source is a useful reference for writing custom
-completion functions.
-@end deftypefun
-
-@deftypefun {char *} username_completion_function (char *text, int state)
-A completion generator for usernames.  @var{text} contains a partial
-username preceded by a random character (usually @samp{~}).  As with all
-completion generators, @var{state} is zero on the first call and non-zero
-for subsequent calls.
-@end deftypefun
-
-@node Completion Variables
-@subsection Completion Variables
-
-@deftypevar {Function *} rl_completion_entry_function
-A pointer to the generator function for @code{completion_matches ()}.
-@code{NULL} means to use @code{filename_entry_function ()}, the default
-filename completer.
-@end deftypevar
-
-@deftypevar {CPPFunction *} rl_attempted_completion_function
-A pointer to an alternative function to create matches.
-The function is called with @var{text}, @var{start}, and @var{end}.
-@var{start} and @var{end} are indices in @code{rl_line_buffer} saying
-what the boundaries of @var{text} are.  If this function exists and
-returns @code{NULL}, or if this variable is set to @code{NULL}, then
-@code{rl_complete ()} will call the value of
-@code{rl_completion_entry_function} to generate matches, otherwise the
-array of strings returned will be used.
-@end deftypevar
-
-@deftypevar {CPFunction *} rl_filename_quoting_function
-A pointer to a function that will quote a filename in an application-
-specific fashion.  This is called if filename completion is being
-attempted and one of the characters in @code{rl_filename_quote_characters}
-appears in a completed filename.  The function is called with
-@var{text}, @var{match_type}, and @var{quote_pointer}.  The @var{text}
-is the filename to be quoted.  The @var{match_type} is either
-@code{SINGLE_MATCH}, if there is only one completion match, or
-@code{MULT_MATCH}.  Some functions use this to decide whether or not to
-insert a closing quote character.  The @var{quote_pointer} is a pointer
-to any opening quote character the user typed.  Some functions choose
-to reset this character.
-@end deftypevar
-
-@deftypevar {CPFunction *} rl_filename_dequoting_function
-A pointer to a function that will remove application-specific quoting
-characters from a filename before completion is attempted, so those
-characters do not interfere with matching the text against names in
-the filesystem.  It is called with @var{text}, the text of the word
-to be dequoted, and @var{quote_char}, which is the quoting character 
-that delimits the filename (usually @samp{'} or @samp{"}).  If
-@var{quote_char} is zero, the filename was not in an embedded string.
-@end deftypevar
-
-@deftypevar {Function *} rl_char_is_quoted_p
-A pointer to a function to call that determines whether or not a specific
-character in the line buffer is quoted, according to whatever quoting
-mechanism the program calling readline uses.  The function is called with
-two arguments: @var{text}, the text of the line, and @var{index}, the
-index of the character in the line.  It is used to decide whether a
-character found in @code{rl_completer_word_break_characters} should be
-used to break words for the completer.
-@end deftypevar
-
-@deftypevar int rl_completion_query_items
-Up to this many items will be displayed in response to a
-possible-completions call.  After that, we ask the user if she is sure
-she wants to see them all.  The default value is 100.
-@end deftypevar
-
-@deftypevar {char *} rl_basic_word_break_characters
-The basic list of characters that signal a break between words for the
-completer routine.  The default value of this variable is the characters
-which break words for completion in Bash, i.e.,
-@code{" \t\n\"\\'`@@$><=;|&@{("}.
-@end deftypevar
-
-@deftypevar {char *} rl_basic_quote_characters
-List of quote characters which can cause a word break.
-@end deftypevar
-
-@deftypevar {char *} rl_completer_word_break_characters
-The list of characters that signal a break between words for
-@code{rl_complete_internal ()}.  The default list is the value of
-@code{rl_basic_word_break_characters}.
-@end deftypevar
-
-@deftypevar {char *} rl_completer_quote_characters
-List of characters which can be used to quote a substring of the line.
-Completion occurs on the entire substring, and within the substring
-@code{rl_completer_word_break_characters} are treated as any other character,
-unless they also appear within this list.
-@end deftypevar
-
-@deftypevar {char *} rl_filename_quote_characters
-A list of characters that cause a filename to be quoted by the completer
-when they appear in a completed filename.  The default is the null string.
-@end deftypevar
-
-@deftypevar {char *} rl_special_prefixes
-The list of characters that are word break characters, but should be
-left in @var{text} when it is passed to the completion function.
-Programs can use this to help determine what kind of completing to do.
-For instance, Bash sets this variable to "$@@" so that it can complete
-shell variables and hostnames.
-@end deftypevar
-
-@deftypevar {int} rl_completion_append_character
-When a single completion alternative matches at the end of the command
-line, this character is appended to the inserted completion text.  The
-default is a space character (@samp{ }).  Setting this to the null
-character (@samp{\0}) prevents anything being appended automatically.
-This can be changed in custom completion functions to
-provide the ``most sensible word separator character'' according to
-an application-specific command line syntax specification.
-@end deftypevar
-
-@deftypevar int rl_ignore_completion_duplicates
-If non-zero, then disallow duplicates in the matches.  Default is 1.
-@end deftypevar
-
-@deftypevar int rl_filename_completion_desired
-Non-zero means that the results of the matches are to be treated as
-filenames.  This is @emph{always} zero on entry, and can only be changed
-within a completion entry generator function.  If it is set to a non-zero
-value, directory names have a slash appended and Readline attempts to
-quote completed filenames if they contain any embedded word break
-characters.
-@end deftypevar
-
-@deftypevar int rl_filename_quoting_desired
-Non-zero means that the results of the matches are to be quoted using
-double quotes (or an application-specific quoting mechanism) if the
-completed filename contains any characters in
-@code{rl_filename_quote_chars}.  This is @emph{always} non-zero
-on entry, and can only be changed within a completion entry generator
-function.  The quoting is effected via a call to the function pointed to
-by @code{rl_filename_quoting_function}.
-@end deftypevar
-
-@deftypevar int rl_inhibit_completion
-If this variable is non-zero, completion is inhibit<ed.  The completion
-character will be inserted as any other bound to @code{self-insert}.
-@end deftypevar
-
-@deftypevar {Function *} rl_ignore_some_completions_function
-This function, if defined, is called by the completer when real filename
-completion is done, after all the matching names have been generated.
-It is passed a @code{NULL} terminated array of matches.
-The first element (@code{matches[0]}) is the
-maximal substring common to all matches. This function can
-re-arrange the list of matches as required, but each element deleted
-from the array must be freed.
-@end deftypevar
-
-@deftypevar {Function *} rl_directory_completion_hook
-This function, if defined, is allowed to modify the directory portion
-of filenames Readline completes.  It is called with the address of a
-string (the current directory name) as an argument.  It could be used
-to expand symbolic links or shell variables in pathnames.

-# In the interest of general portability, some common bourne shell
-# constructs were avoided because they weren't guaranteed to be available
-# in some earlier implementations.  I've tried to make this program as
-# portable as possible.  Welcome to unix, where the lowest common
-# denominator is rapidly diminishing.
-#
-# Among the more interesting lossages I noticed with some bourne shells
-# are:
-#     * No shell functions.
-#     * No `unset' builtin.
-#     * `shift' cannot take a numeric argument, and signals an error if
-#       there are no arguments to shift.
-
-# Code:
-
-# Name by which this script was invoked.
-progname=`echo "$0" | sed -e 's/[^\/]*\///g'`
-
-# This string is expanded by rcs automatically when this file is checked out.
-rcs_revision='$Revision$'
-version=`set - $rcs_revision; echo $2`

-.TH TEXI2HTML 1 "09/10/96"
-.AT 3
-.SH NAME
-texi2html \- a Texinfo to HTML converter
-.SH SYNOPSIS
-.B texi2html [options] file
-.PP
-.B texi2html -check [-verbose] files
-.SH DESCRIPTION
-.I Texi2html
-converts the given Texinfo file to a set of HTML files. It tries to handle
-most of the Texinfo commands. It creates hypertext links for cross-references,
-footnotes...
-.PP
-It also tries to add links from a reference to its corresponding entry in the
-bibliography (if any). It may also handle a glossary (see the
-.B \-glossary
-option).
-.PP
-.I Texi2html
-creates several files depending on the contents of the Texinfo file and on
-the chosen options (see FILES).
-.PP
-The HTML files created by
-.I texi2html
-are closer to TeX than to Info, that's why
-.I texi2html
-converts @iftex sections and not @ifinfo ones by default. You can reverse
-this with the \-expandinfo option.
-.SH OPTIONS
-.TP 12
-.B \-check
-Check the given file and give the list of all things that may be Texinfo commands.
-This may be used to check the output of
-.I texi2html
-to find the Texinfo commands that have been left in the HTML file.
-.TP
-.B \-expandinfo
-Expand @ifinfo sections, not @iftex ones.
-.TP
-.B \-glossary
-Use the section named 'Glossary' to build a list of terms and put links in the HTML
-document from each term toward its definition.
-.TP
-.B \-invisible \fIname\fP
-Use \fIname\fP to create invisible destination anchors for index links. This is a workaround
-for a known bug of many WWW browsers, including xmosaic.
-.TP
-.B \-I \fIdir\fP
-Look also in \fIdir\fP to find included files.
-.TP
-.B \-menu
-Show the Texinfo menus; by default they are ignored.
-.TP
-.B \-monolithic
-Output only one file, including the table of contents and footnotes.
-.TP
-.B \-number
-Number the sections.
-.TP
-.B \-split_chapter
-Split the output into several HTML files (one per main section:
-chapter, appendix...).
-.TP
-.B \-split_node
-Split the output into several HTML files (one per node).
-.TP
-.B \-usage
-Print usage instructions, listing the current available command-line options.
-.TP
-.B \-verbose
-Give a verbose output. Can be used with the
-.B \-check
-option.
-.PP
-.SH FILES
-By default
-.I texi2html
-creates the following files (foo being the name of the Texinfo file):
-.TP 16
-.B foo_toc.html
-The table of contents.
-.TP
-.B foo.html
-The document's contents.
-.TP
-.B foo_foot.html
-The footnotes (if any).
-.PP
-When used with the
-.B \-split
-option, it creates several files (one per chapter or node), named
-.B foo_n.html
-(n being the indice of the chapter or node), instead of the single
-.B foo.html
-file.
-.PP
-When used with the
-.B \-monolithic
-option, it creates only one file:
-.B foo.html
-.SH VARIABLES
-.I texi2html
-predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
-.SH ADDITIONAL COMMANDS
-.I texi2html
-implements the following non-Texinfo commands:
-.TP 16
-.B @ifhtml
-This indicates the start of an HTML section, this section will passed through
-without any modofication.
-.TP
-.B @end ifhtml
-This indcates the end of an HTML section.
-.SH VERSION
-This is \fItexi2html\fP version 1.51, 09/10/96.
-.PP
-The latest version of \fItexi2html\fP can be found in WWW, cf. URL
-http://wwwcn.cern.ch/dci/texi2html/
