           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.

           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.

           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.

           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.

           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.

           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 [e-mail]

           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 [e-mail]

           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.

           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 [e-mail]

           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).
