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. + +16/10/2001 mcs@astro.caltech.edu + + history.c history.h getline.c libtecla.h libtecla.map + man3/gl_get_line.3 man3/gl_resize_history.3 + 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. + +13/10/2001 mcs@astro.caltech.edu + + getline.c + tputs_fp is now only declared if using termcap or + terminfo. + getline.c libtecla.map man3/gl_get_line.3 + 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. + +01/10/2001 mcs@astro.caltech.edu + + getline.c history.c history.h man3/gl_get_line.3 + 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 + ceiling to infinity. + +01/10/2001 mcs@astro.caltech.edu + + configure.in configure + Under digital unix, getline wouldn't compile with + _POSIX_C_SOURCE set, due to type definitions needed by + select being excluded by this flag. Defining the + _OSF_SOURCE macro as well on this system, resolved this. + +30/09/2001 mcs@astro.caltech.edu + + getline.c libtecla.h history.c history.h man3/gl_get_line.3 + man3/gl_group_history.3 + 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 + current stream identifier. + getline.c libtecla.h history.c history.h man3/gl_get_line.3 + man3/gl_show_history.3 + The new gl_show_history function displays the current + history to a given stdio output stream. + +29/09/2001 mcs@astro.caltech.edu + + 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. + +28/09/2001 mcs@astro.caltech.edu + + version.c Makefile.rules + I added a function for querying the version number of + the library. + +26/09/2001 mcs@astro.caltech.edu + + getline.c man3/gl_get_line.3 + I added the new gl_watch_fd() function, which allows + applications to register callback functions to be invoked + when activity is seen on arbitrary file descriptors while + gl_get_line() is awaiting keyboard input from the user. + + keytab.c + If a request is received to delete a non-existent + binding, which happens to be an ambiguous prefix of other + bindings no complaint is now generated about it being + ambiguous. + +23/09/2001 mcs@astro.caltech.edu + + getline.c history.c history.h man3/gl_get_line.3 + libtecla.map demo.c + I added new public functions for saving and restoring the + contents of the history list. The demo program now uses + these functions to load and save history in ~/.demo_history. + +23/09/2001 mcs@astro.caltech.edu + + getline.c + On trying the demo for the first time on a KDE konsole + terminal, I discovered that the default M-O binding + to repeat history was hiding the arrow keys, which are + M-OA etc. I have removed this binding. The M-o (ie the + lower case version of this), is still bound. + +18/09/2001 mcs@astro.caltech.edu + + getline.c man3/gl_get_line.3 libtecla.map + 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 + in gl_get_line.3. + +08/09/2001 mcs@astro.caltech.edu + + getline.c man3/gl_get_line.3 + It is now possible to bind actions to key-sequences + that start with printable characters. Previously + keysequences were required to start with meta or control + characters. This is documented in gl_get_line.3. + + getline.c man3/gl_get_line.3 + A customized completion function can now arrange for + gl_get_line() to return the current input line whenever a + successful completion has been made. This is signalled by + setting the last character of the optional continuation + suffix to a newline character. This is documented in + gl_get_line.3. + +05/07/2001 Bug reported by Mike MacFaden, fixed by mcs + + 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. + +05/07/2001 Bug reported and patched by Mike MacFaden (patch modified + by mcs to match original intentions). + + getline.c + getline.c wouldn't compile when termcap was selected as + the terminal information database. setupterm() was being + 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. + +02/07/2001 Version 1.3.3 released. + +27/06/2001 mcs@astro.caltech.edu + + getline.c expand.c cplmatch.c + Added checks to fprintf() statements that write to the + terminal. + getline.c + Move the cursor to the end of the line before suspending, + so that the cursor doesn't get left in the middle of the + input line. + Makefile.in + On systems that don't support shared libraries, the + distclean target of make deleted libtecla.h. This has + now been fixed. + 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. + +21/05/2001 Version 1.3.2 released. + +21/05/2001 mcs@astro.caltech.edu + + getline.c + When vi-replace-char was used to replace the character at + the end of the line, it left the cursor one character to + 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 find-parenthesis (%), delete-to-paren (M-d%), + vi-change-to-paren (M-c%), copy-to-paren (M-y%). + cplfile.c pcache.c + In three places I was comparing the last argument of + strncmp() to zero instead of the return value of + strncmp(). + +20/05/2001 mcs@astro.caltech.edu + + 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.

Fixed. + +30/04/2001 mcs@astro.caltech.edu + + 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. + +30/04/2001 mcs@astro.caltech.edu + + getline.c + In gl_get_input_line(), don't redundantly copy the + start_line if start_line == gl->line. + +30/04/2001 Version 1.3.0 released. + +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. + +25/03/2001 Markus Gyger (logged here by mcs) + + Makefile.in: + Make symbolic links to alternative shared library names + relative instead of absolute. + Makefile.rules: + The HP-UX libtecla.map.opt file should be made in the + compilation directory, to allow the source code directory + to be on a readonly filesystem. + 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.

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.

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 Version 1.2.3 released. + +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. + +04/03/2001 mcs@astro.caltech.edu + + configure.in Makefile.in Makefile.stub configure config.guess + config.sub Makefile.rules install-sh PORTING README INSTALL + 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 + PORTING file. + +24/02/2001 Version 1.2b released. + +22/02/2001 mcs@astro.caltech.edu + + 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. + +18/02/2001 Version 1.2a released. + +18/02/2001 mcs@astro.caltech.edu + + getline.c + 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. + +12/02/2001 Markus Gyger (described here by mcs) + + man3/pca_lookup_file.3 man3/gl_get_line.3 + man3/ef_expand_file.3 man3/cpl_complete_word.3 + In the 1.2 release of the library, all functions in the + library were given man pages. Most of these simply + 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 + named there. + +11/02/2001 mcs@astro.caltech.edu + + getline.c + 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. + +09/02/2001 Version 1.2 released. + +04/02/2001 mcs@astro.caltech.edu + + 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. + +28/01/2001 mcs@astro.caltech.edu + + 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. + +04/01/2001 mcs@astro.caltech.edu (Release of version 1.1j) + + 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. + +30/12/2000 mcs@astro.caltech.edu + + 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 + line to be passed in the start_line argument. + 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) + + 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. + +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++. + +19/11/2000 mcs@astro.caltech.edu + 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. + + man/cpl_complete_word.3 html/cpl_complete_word.html + man/ef_expand_file.3 html/ef_expand_file.html + man/gl_get_line.3 html/gl_get_line.html + I added sections on thread safety to the man pages of the + individual modules. + + man/gl_get_line.3 html/gl_get_line.html + I documented the new gl_change_terminal() function. + + man/gl_get_line.3 html/gl_get_line.html + In the description of the ~/.teclarc configuration file, + I had omitted the 'bind' command word in the example + entry. I have now remedied this. |
