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. - -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. |
