-
-Thu Feb 1 17:50:22 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
-
- * Makefile (libreadline.a): Uncomment out ranlib line.
-
-Sun Nov 26 16:29:11 1989 Jim Kingdon (kingdon at hobbes.ai.mit.edu)
-
- * readline.c (rl_deprep_terminal): Only restore local_mode_flags
- if they had been set.
-
-Thu Oct 19 17:18:40 1989 Jim Kingdon (kingdon at hobbes.ai.mit.edu)
-
- * Move vi_doing_insert from vi_mode.c to readline.c
-
- * readline.c: Move compare_strings before its use.
- Remove declarations.
-
- * readline.c: Move defining_kbd_macro above rl_dispatch.
- (rl_dispatch): Remove "extern int defining_kbd_macro".
-
-Mon Oct 16 11:56:03 1989 Jim Kingdon (kingdon at hobbes.ai.mit.edu)
-
- * readline.c (rl_set_signals): Remove unnecessary "static int
- rl_signal_handler()".
-
-Sat Sep 30 14:51:56 1989 Jim Kingdon (kingdon at hobbes.ai.mit.edu)
-
- * readline.c (rl_initialize): Change parsing_conditionalized_out
- to static.
- (rl_dispatch): Change defining_kbd_macro to static.
- (rl_newline): Change vi_doing_insert to static.
-
-Fri Sep 8 09:00:45 1989 Brian Fox (bfox at aurel)
-
- * readline.c: rl_prep_terminal (). Only turn on 8th bit
- as meta-bit iff the terminal is not using parity.
-
-Sun Sep 3 08:57:40 1989 Brian Fox (bfox at aurel)
-
- * readline.c: start_insert (). Uses multiple
- insertion call in cases where that makes sense.
-
- rl_insert (). Read type-ahead buffer for additional
- keys that are bound to rl_insert, and insert them
- all at once. Make insertion of single keys given
- with an argument much more efficient.
-
-Tue Aug 8 18:13:57 1989 Brian Fox (bfox at aurel)
-
- * readline.c: Changed handling of EOF. readline () returns
- (char *)EOF or consed string. The EOF character is read from the
- tty, or if the tty doesn't have one, defaults to C-d.
-
- * readline.c: Added support for event driven programs.
- rl_event_hook is the address of a function you want called
- while Readline is waiting for input.
-
- * readline.c: Cleanup time. Functions without type declarations
- do not use return with a value.
-
- * history.c: history_expand () has new variable which is the
- characters to ignore immediately following history_expansion_char.
-
-Sun Jul 16 08:14:00 1989 Brian Fox (bfox at aurel)
-
- * rl_prep_terminal ()
- BSD version turns off C-s, C-q, C-y, C-v.
-
- * readline.c -- rl_prep_terminal ()
- SYSV version hacks readline_echoing_p.
- BSD version turns on passing of the 8th bit for the duration
- of reading the line.
-
-Tue Jul 11 06:25:01 1989 Brian Fox (bfox at aurel)
-
- * readline.c: new variable rl_tilde_expander.
- If non-null, this contains the address of a function to call if
- the standard meaning for expanding a tilde fails. The function is
- called with the text sans tilde (as in "foo"), and returns a
- malloc()'ed string which is the expansion, or a NULL pointer if
- there is no expansion.
-
- * readline.h - new file chardefs.h
- Separates things that only readline.c needs from the standard
- header file publishing interesting things about readline.
-
- * readline.c:
- readline_default_bindings () now looks at terminal chararacters
- and binds those as well.
-
-Wed Jun 28 20:20:51 1989 Brian Fox (bfox at aurel)
-
- * Made readline and history into independent libraries.
