Wed Jun 10 1998  Bruno Haible  <bruno@linuix.mathematik.uni-karlsruhe.de>
	
	* configure.in, acconfig.h, config.h.in: Add CL_SIGNALBLOCK.
	* history.c (history_search_internal): Fix declaration.
	* complete.c (rl_complete_internal): Always return a value.
	
Thu Aug 11 1994  Bruno Haible  (haible@ma2s2.mathematik.uni-karlsruhe.de)

	* rldefs.h, config.in, configure: massive changes. Hopefully
	  better autoconfiguring.

	* rltty.c (control_keypad), readline.c (term_ks, term_ke): Remove.
	  Sending unsollicited control characters makes up for too much
	  confusion with the terminal driver. (On Linux: Backspacing over
	  tabs is disturbed on any tty, and chaning NumLock is disabled
	  on the console.)

Wed Aug 10 1994  Bruno Haible  (haible@ma2s2.mathematik.uni-karlsruhe.de)

	* signals.c (rl_set_signals, rl_clear_signals): When reinstalling
	  handlers using sigaction, use the same sa_flags and sa_mask
	  that was present when the handler was deinstalled. Otherwise
	  readline's signal handling would not be transparent.
	  signals.c (rl_sigaction): New function.

	* configure.in, configure, config.h.in, parens.c: Proper detection
	  of whether the function select() is available. Previously select()
	  failed to be detected on Linux.

	* complete.c (rl_complete_internal): Remove unused variable `quoted'.
	* display.c (rl_redisplay): Remove unused variable `wrap_column'.
	* display.c: Remove unused variable `last_prompt_string'.
	* signals.c: Remove unused variable `old_cont'.

	* complete.c (rl_complete_internal): Remove a "special case" which
	  is not special at all. Simplify the printing loop.

	* readline.h: Declare that rl_abort() doesn't return. GCC will
	  produce fewer warnings.

	* vi_mode.c (rl_vi_replace): Use KEYMAP_SIZE instead of 127 or 128.
	* bind.c (rl_invoking_keyseqs_in_map): Use KEYMAP_SIZE instead of 128.

	* complete.c (rl_complete_internal): On SunOS 4, strcmp() compares
	  signed characters, not unsigned characters. Therefore it is not
	  guaranteed that matches[0] will remain in place. Work around.

	* readline.c, rltty.c: The __GO32__ include file <sys/pc.h> is now
	  called <pc.h>.

	* readline.c (rl_gather_tyi): Fix the __GO32__ branch. rl_getc()
	  didn't really work, kbhit() does.

	* keymaps.c (rl_make_keymap): 126 is an Ascii character. Fix
	  off-by-1 bug.

	* readline.c (readline_internal): force lastc and eof_found to be
	  allocated on the stack.

	* rldefs.h: Remove __linux__ special case. HAVE_TERMCAP_H is already
	  defined on Linux.

	* tilde.c (tilde_expand_word): Use alloca() instead of a fixed-sized
	  buffer.

	* tilde.h. keymaps.h, memalloc.h: Don't use identifiers beginning
	  with two underscores. They are not in our namespace.

	* signals.c (rl_signal_handler): Ignore SIGALRM as well until
	  rl_clear_signals resets the catcher. Need this for slow
	  HP-UX machines.
	  From Gabor Herr <herr@iti.informatik.th-darmstadt.de> Dec 7 1993.

Wed Aug 10 1994  Bruno Haible  (haible@ma2s2.mathematik.uni-karlsruhe.de)

	* readline.h, readline.c (rl_already_prompted): New variable.
	  Some applications have output the prompt themselves. readline
	  needs to know about the prompt (for cursor movement) but must
	  not output the prompt in the first run.
	* display.c (rl_on_new_line_with_prompt): New function.

	* readline.h, complete.c (rl_basic_quote_characters): New variable.
	  For languages like Lisp.
	* parens.c: Use it.

	* readline.c (rl_present_p): Add constant flag. A replacement
	  library libnoreadline.a shall define rl_present_p = 0. An
	  application can then determine at run time whether is was linked
	  with libreadline.a or libnoreadline.a.

Wed Aug 10 1994  Bruno Haible  (haible@ma2s2.mathematik.uni-karlsruhe.de)

	* chardefs.h: Added proper support (including to_upper, to_lower)
	  for the 8-bit character sets ISO Latin-1, DOS, NeXTstep.

	* emacs_keymap.c (emacs_dos_keymap): keymap for DOS.
	* history.c (history_filename): Use "!history" instead of ".history"
	  on DOS.
	* rlconf.h (DEFAULT_INPUTRC): Use "/!inputrc" instead of "~/.inputrc"
	  on DOS.
	* rldefs.h, readline.c (rl_getc), rltty.c (prepare_terminal_settings):
	  Support for raw mode on DOS.
	* rltty.c (rl_prep_terminal): Use Ctrl-Z instead of Ctrl-D as EOF
	  character on DOS.
	* readline.c (_rl_set_screen_size, init_terminal_io): Get the
	  real screen size, not a dummy one, from EMX.
	* signals.c (rl_signal_handler): Support EMX.

Wed Aug 10 1994  Bruno Haible  (haible@ma2s2.mathematik.uni-karlsruhe.de)

	* overall: added ANSI C prototypes, such that the library can be
	  compiled using "gcc -Wall -Wmissing-prototypes".

Mon Mar 22 19:16:05 1993  Brian Fox  (bfox@eos.crseo.ucsb.edu)

	* dispose_cmd.c, several other files. Declare dispose_xxx () as
	"void".

	* builtins/hashcom.h: Make declarations of hashed_filenames be
	"extern" to keep the SGI compiler happy.

	* readline.c (rl_initialize_everything): Assign values to
	out_stream and in_stream immediately, since
	output_character_function () can be called before
	readline_internal () is called.

Tue Dec  8 09:30:56 1992  Brian Fox  (bfox@cubit)

	* readline.c (rl_init_terminal) Set PC from BC, not from *buffer.

Mon Nov 30 09:35:47 1992  Brian Fox  (bfox@cubit)

	* readline.c (invoking_keyseqs_in_map, rl_parse_and_bind) Allow
	backslash to quote characters, such as backslash, double quote,
	and space. Backslash quotes all character indiscriminately.

	* funmap.c (vi_keymap) Fix type in "vi-replace" declaration.

Fri Nov 20 10:55:05 1992  Brian Fox  (bfox@cubit)

	* readline.c (init_terminal_io, rl_prep_terminal): FINALLY!

	parameters.

Thu Oct  8 08:53:07 1992  Brian J. Fox  (bfox@helios)

	becomes zero.

Tue Jul 28 09:28:41 1992  Brian Fox  (bfox@cubit)

	* readline.c (rl_variable_bind): New local structure describes
	booleans by name and address; code in rl_variable_bind () looks at
	structure to set simple variables.

	* parens.c (rl_insert_close): New variable rl_blink_matching_paren
	is non-zero if we want to blink the matching open when a close is
	inserted.  If FD_SET is defined, rl_blink_matching_paren defaults
	to 1, else 0.  If FD_SET is not defined, and
	rl_blink_matching_paren is non-zero, the close character(s) are/is
	simply inserted.

	is called meta_flag.

Thu Jul  9 10:37:56 1992  Brian Fox  (bfox@cubit)

	* history.c (get_history_event) Change INDEX to LOCAL_INDEX.  If
	compiling for the shell, allow shell metacharacters to separate
	history tokens as they would for shell tokens.

Sat Jul  4 19:29:12 1992  Brian Fox  (bfox@cubit)

	* vi_keymap.c: According to Posix, TAB self-inserts instead of
	doing completion.

	* vi_mode.c: (rl_vi_yank_arg) Enter VI insert mode after yanking
	an arg from the previous line.

	* search.c: New file takes over vi style searching and implements
	non-incremental searching the history.

	called from rl_set_signals () and rl_clear_signals ().

Fri May  8 12:50:15 1992  Brian Fox  (bfox@cubit)

	* readline.c: (readline_default_bindings) Do comparisons with
	_POSIX_VDISABLE casted to `unsigned char'.  Change tty characters
	to be unsigned char.

Thu Apr 30 12:36:35 1992  Brian Fox  (bfox@cubit)

	* readline.c: (rl_getc) Handle "read would block" error on
	non-blocking IO streams.

	* readline.c: (rl_signal_handler): Unblock only the signal that we
	have caught, not all signals.

Sun Feb 23 03:33:09 1992  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c: Many functions.  Use only the macros META_CHAR and
	UNMETA to deal with meta characters.  Prior to this, we used
	numeric values and tests.

	* history.c (history_do_write) Build a buffer of all of the lines
	to write and write them in one fell swoop (lower overhead than
	calling write () for each line).  Suggested by Peter Ho.

	* readline.c: Include hbullx20 as well as hpux for determining
	USGr3ness.

	* readline.c (rl_unix_word_rubout) As per the "Now REMEMBER"
	comment, pass arguments to rl_kill_text () in the correct order to
	preserve prepending and appending of killed text.

	* readline.c (rl_search_history) malloc (), realloc (), and free
	() SEARCH_STRING so that there are no static limits on searching.

	the other.  New defines used HAVE_POSIX_SIGNALS, and
	TERMIOS_TTY_DRIVER.

Tue Jul 30 22:37:26 1991  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c: rl_getc () If a call to read () returns without an
	error, but with zero characters, the file is empty, so return EOF.

Thu Jul 11 20:58:38 1991  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c: (rl_get_next_history, rl_get_previous_history)
	Reallocate the buffer space if the line being moved to is longer
	the the current space allocated.  Amazing that no one has found
	this bug until now.

Sun Jul  7 02:37:05 1991  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c:(rl_parse_and_bind) Allow leading whitespace.

	rl_dump_functions (), and rl_function_dumper ().

	funmap.c: support for same includes rl_funmap_names ().

	readline.c, funmap.c: no longer define STATIC_MALLOC.  However,
	update both version of xrealloc () to handle a null pointer.

	executed.  Fixed typo in username_completion_function ().

Mon Apr  9 19:55:48 1990  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c: username_completion_function (); For text passed in
	with a leading `~', remember that this could be a filename (after
	it is completed).

Thu Apr  5 13:44:24 1990  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c: rl_search_history (): Correctly handle case of an
	unfound search string, but a graceful exit (as with ESC).

	* readline.c: rl_restart_output ();  The Apollo passes the address
	of the file descriptor to TIOCSTART, not the descriptor itself.

Tue Mar 20 05:38:55 1990  Brian Fox  (bfox at gnuwest.fsf.org)

	* readline.c: rl_complete (); second call in a row causes possible
	completions to be listed.

	* readline.c: rl_redisplay (), added prompt_this_line variable
	which is the first character character following \n in prompt.

Sun Mar 11 04:32:03 1990  Brian Fox  (bfox at gnuwest.fsf.org)

	* Signals are now supposedly handled inside of SYSV compilation.

Wed Jan 17 19:24:09 1990  Brian Fox  (bfox at sbphy.ucsb.edu)

	* history.c: history_expand (); fixed overwriting memory error,
	added needed argument to call to get_history_event ().

Thu Jan 11 10:54:04 1990  Brian Fox  (bfox at sbphy.ucsb.edu)

	* readline.c: added mark_modified_lines to control the
	display of an asterisk on modified history lines.  Also
	added a user variable called mark-modified-lines to the
	`set' command.

Thu Jan  4 10:38:05 1990  Brian Fox  (bfox at sbphy.ucsb.edu)

	  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)

	  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.
