           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.

           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.

           enhance.c
             Use argv[0] in error reports instead of using a
             hardcoded macro.

07/12/2001 [e-mail]
           getline.c
             The cut buffer wasn't being cleared after being
             used as a work buffer by gl_load_history().

06/12/2001 [e-mail]
           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 [e-mail]
           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.

           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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.

           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           man3/enhance.3 man3/libtecla.3
             I started writing a man page for the enhance program.

26/11/2001 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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 [e-mail]
           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.

           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.

           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.

           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.
