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