This changeset adds support for:
* rl_prep_terminal(),
* rl_deprep_terminal(), both of which are only wrappers to rl_ttyset().
* rl_getc()
and:
* (*rl_getc_function), defaults to rl_getc()
* (*rl_event_hook)
* (*rl_prep_term_function), defaults to rl_prep_terminal()
* (*rl_deprep_term_function), defaults to rl_deprep_terminal()
For further details, see http://www.cs.unc.edu/~tell/dist/magic-readline.README
Differences from Steve's commit include: signal safety in rl_getc(), restart
read() on EINTR, and make sure to support "int meta_flag" to rl_prep_terminal()
which is the GNU syntax. To that end I reused the inverse of rl_meta_chars.
This changeset fixes an old Debian patch that attempted to fix the display
of 8-bit characters in the function emacs(). It accidentally crippled the
function of M-d and M-DEL. The latter was however also broken by being
mapped to wipe(), more on that below.
The real fix is to set rl_meta_chars to 0 by default and in the tty_show()
function, which tried to be smart and output control and meta characters
(in the wrong order as well). Simply disabling the special code for output
of control characters fixes 8-bit input.
We also nuke the old and broken wipe() function that was mapped to M-DEL,
instead we map that key binding to bk_kill_word(), which works.
Instead merge afd8b4de9dca8ec6afc3 from http://github.com/heimdal/heimdal.git project.
This lets rl_complete() and rl_list_possib() become wrapper functions calling a set of
function pointers, set using rl_set_complete_func() and rl_set_list_possib_funct().
Each wrapper has a fallback to do filename completion, which in turn can be disabled
by leaving out --enable-default-complete from the configure line.
This change, admittedly quite intrusive for a library, is a better implementation in
many ways. For one it is much more readable, but it also enables further adoption of
other editline forks as well as a simpler implementation of GNU Readline function
pointers rl_completion_entry_function and rl_attempted_completion_function at a later
stage.
My apologies to everyone for whom this change breaks backwards compatibility. For
help on converting your code, please see examples/cli.c.
Remove all old $Id:$ and similar constructs, they don't provide any
additional benefit anymore.
Add configure options for toggling terminal bell and toying with
SIGSTOP using Ctrl-Z. Rename config option for ANSI keys to get
a consistent namespace.
Also did some work on ANSI-fication of function definitions, lot's
of that was still lingering around.
=====================
Lots of minor fixes and additions:
* Bump version info in configure.ac
* User editline.h added, installs to $prefix/include/editline.h
- Based on Debian package version, but heavily updated.
* Manpage installs to $prefix/share/man/man3/editline.3
- Also slightly updated with contents from Debian package.
* Revised README to mention existing Debian package, also cleaned
out the old README, which now lives in doc/README
* Add TODO file.
* Fix package description and make dist to bzip2 tarballs.
