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.
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. 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,
vi-forward-change-to, vi-backward-change-to,
vi-change-goto-col, forward-delete-find, backward-delete-find,
forward-delete-to, backward-delete-to,
delete-refind, delete-invert-refind, forward-copy-find,
backward-copy-find, forward-copy-to, backward-copy-to
copy-goto-column, copy-rest-of-line, copy-to-bol, copy-line,
history-re-search-forward, history-re-search-backward.
06/05/2001 Version 1.3.1 released.
03/05/2001 mcs@astro.caltech.edu
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
number (2.5.1). 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. This enables
Markus' changes to "configure.in" documented previously,
(see 17/03/2001).
20/03/2001 John Levon (logged here by mcs)
libtecla.h
A couple of the function prototypes in libtecla.h have
(FILE *) argument declarations, which means that stdio.h
needs to be included. The header file should be self
contained, so libtecla.h now includes stdio.h.
18/03/2001 Version 1.2.4 released.
README html/index.html configure.in
Incremented minor version from 3 to 4.
18/03/2001 mcs@astro.caltech.edu
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
int Makefile.rules instead of Makefile.in.
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 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.

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.

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.

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.

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.
