   4
   5 Wed Apr 13 21:28:44 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
   6
   7         * rltty.c (set_tty_settings): Don't set readline_echoing_p.
   8         (rl_deprep_terminal) [NEW_TTY_DRIVER]: Set readline_echoing_p.
   9
  10 Sun Mar 13 09:13:12 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  11
  12         * Makefile.in: Add TAGS target.
  13
  14 Wed Mar  9 18:01:31 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  15
  16         * isearch.c, search.c: Include sysdep.h.
  17
  18 Thu Mar  3 17:40:03 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  19
  20         * configure.in: For ISC, use mh-sysv, not mh-isc.
  21
  22 Thu Feb 24 04:13:53 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  23
  24         * Merge in changes from bash-1.13.5. Merge changes from glob/tilde.c
  25         into tilde.c and use it. Add system function declarations where
  26         necessary. Check for __GO32__, not _GO32_ consistently.
  27         * Makefile.in:  Update dependencies.
  28         * rltty.c:  Include <sys/file.h> to match include file setup
  29         in readline.c for rldefs.h. Otherwise we get inconsistent
  30         TTY_DRIVER definitions in readline.c and rltty.c.
  31         * bind.c, complete.c:  Do not include <sys/types.h>, it is already
  32         included via sysdep.h, which causes problems if <sys/types.h> has
  33         no multiple inclusion protection.
  34         * readline.c (_rl_set_screen_size):  Reestablish test for
  35         TIOCGWINSZ_BROKEN.
  36         * rldefs.h:  Define S_ISREG if necessary.
  37
  38 Fri Feb 18 08:56:35 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  39
  40         * Makefile.in: Add search.o rule for Sun make.
  41
  42 Wed Feb 16 16:35:49 1994  Per Bothner  (bothner@kalessin.cygnus.com)
  43
  44         * rltty.c:  #if out some code if __GO32__.
  45
  46 Tue Feb 15 14:07:08 1994  Per Bothner  (bothner@kalessin.cygnus.com)
  47
  48         * readline.c (_rl_output_character_function), display.c:
  49         Return int, not void, to conform with the expected arg of tputs.
  50         * readline.c (init_terminal_io):  tgetflag only takes 1 arg.
  51         * readline.c (_rl_savestring):  New function.
  52         * chardefs.h:  To avoid conflicts and/or warnings, define
  53         savestring as a macro wrapper for _rl_savestring.
  54         * display.c (extern term_xn):  It's an int flag, not a string.
  55         * charsdefs.h, rldefs.h:  Remove HAVE_STRING_H-related junk.
  56
  57 Sat Feb  5 08:32:30 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  58
  59         * Makefile.in: Remove obsolete rules for history.info and
  60         readline.info.
  61
  62 Thu Jan 27 17:04:01 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  63
  64         * chardefs.h: Only declare strrchr if it is not #define'd.
  65
  66 Tue Jan 25 11:30:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  67
  68         * rldefs.h: Accept __hpux as well as hpux for HP compiler in ANSI mode.
  69
  70 Fri Jan 21 17:31:26 1994  Jim Kingdon  (kingdon@lisa.cygnus.com)
  71
  72         * chardefs.h, tilde.c: Just declare strrchr rather than trying to
  73         include a system header.
  74
  75 Fri Jan 21 14:40:43 1994  Fred Fish  (fnf@cygnus.com)
  76
  77         * Makefile.in (distclean, realclean):  Expand local-distclean
  78         inline after doing recursion.  You can't recurse after removing
  79         Makefile.  Make them depend on local-clean.
  80         * Makefile.in (local-distclean):  Remove now superfluous target.
  81
  82 Mon Jan 17 12:42:07 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
  83
  84         * readline.c (doing_an_undo): Delete second declaration, since it
  85         confuses the alpha-osf1 native compiler.
  86
  87 Sun Jan 16 12:33:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  88
  89         * complete.c, bind.c: Include <sys/stat.h>.
  90         * complete.c: Define X_OK if not defined by a system header.
  91
  92         * chardefs.h: Don't declare xmalloc.
  93
  94         * keymaps.h: Include "chardefs.h" not <readline/chardefs.h>.
  95
  96         * Makefile.in (clean mostlyclean distclean realclean): Recurse
  97         into subdirectories as well as doing this directory.  Add clean-dvi
  98         target.
  99

 101
 102         * readline.c, display.c:  Patches to allow use of all 80
 103         columns on most terminals (those with am and xn).
 104
 105         Merge in changes from bash-1.13.  The most obvious one is
 106         that the file readline.c has been split into multiple files.
 107         * bind.c, complete.c, dispay.c, isearch.c, parens.c, rldefs.h,
 108         rltty.c, search.c signals.c, tilde.c, tilde.h, xmalloc.c:  New files.
 109

 111
 112         * readline.c (rl_getc): If GO32, trim high bit from getkey,
 113         otherwise fancy PC keys cause grief.
 114
 115 Fri Nov  5 11:49:47 1993  Jim Kingdon  (kingdon@lioth.cygnus.com)
 116
 117         * configure.in: Add doc to configdirs.

 126         * readline.c: Add stuff for HIUX to place where we detect termio
 127         vs. sgtty (ugh, but I don't see a simple better way).
 128
 129 Wed Sep 29 11:02:58 1993  Jim Kingdon  (kingdon@lioth.cygnus.com)
 130
 131         * readline.c (parser_if): Free tname when done with it (change
 132         imported from from bash 1.12 readline).
 133
 134 Tue Sep  7 17:15:37 1993  Jim Kingdon  (kingdon@lioth.cygnus.com)
 135
 136         * configure.in (m88k-*-sysvr4*): Comment out previous change.

 176         * configure.in: recognize *-*-solaris2* instead of *-*-solaris* (a
 177         number of people want to call SunOS 4.1.2 "solaris1.0"

 272
 273         * readline.c: Make new SIGNALS_* macros to parameterize the
 274         ugly changes in signal blocking.  Use them throughout,
 275         reducing #ifdef HAVE_POSIX_SIGNALS and HAVE_BSD_SIGNALS clutter
 276         significantly.  Make all such places use POSIX if available,
 277         to avoid losing with poor `sigsetmask' emulation from libiberty.

 302
 303         * readline.c:  Can't initialize FILE *'s with stdin and stdout,
 304         because they might not be constant.  Patch from Tom Quinn,

 316
 317 Tue Apr 21 11:54:23 1992  K. Richard Pixley  (rich@cygnus.com)

 338         to write and write them in one fell swoop (lower overhead than
 339         calling write () for each line).  Suggested by Peter Ho.

 354           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
 355           copyrights to '92, changed some from Cygnus to FSF.

 363         * readline.c (rl_read_init_file):  Make sure that null filename is
 364         not passed to open() or else we end up opening the directory, and
 365         read a bunch of garbage into keymap[].

 368
 369         * readline.c (readline_default_bindings):  Only make use of VLNEXT
 370         when both VLNEXT and TERMIOS_TTY_DRIVER is defined.  On SVR4
 371         <termio.h> includes <termios.h>, so VLNEXT is always defined.
 372
 373         * sysdep-norm.h (_POSIX_VERSION):  Define this for all SVR4
 374         systems so that <termios.h> gets used, instead of <termio.h>.

 430
 431         * Makefile.in, config/hm-sysv, config/hm-sco:  Change SYSV to
 432         USG to match current usage.
 433
 434         * readline.c:  Add USGr4 to list of defined things to check for
 435         to use <dirent.h> style directory access.

 456         systems also.
 457
 458 Thu Oct  3 16:19:53 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 459
 460         * readline.c; Make a distinction between having a TERMIOS tty
 461         driver, and having POSIX signal handling.  You might one without
 462         the other.  New defines used HAVE_POSIX_SIGNALS, and
 463         TERMIOS_TTY_DRIVER.
 464
 465 Tue Jul 30 22:37:26 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 466
 467         * readline.c: rl_getc () If a call to read () returns without an
 468         error, but with zero characters, the file is empty, so return EOF.
 469
 470 Thu Jul 11 20:58:38 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 471
 472         * readline.c: (rl_get_next_history, rl_get_previous_history)
 473         Reallocate the buffer space if the line being moved to is longer
 474         the the current space allocated.  Amazing that no one has found
 475         this bug until now.

 477 Sun Jul  7 02:37:05 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 478
 479         * readline.c:(rl_parse_and_bind) Allow leading whitespace.
 480           Make sure TERMIO and TERMIOS systems treat CR and NL
 481           disctinctly.
 482
 483 Tue Jun 25 04:09:27 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 484
 485         * readline.c: Rework parsing conditionals to pay attention to the
 486         prior states of the conditional stack.  This makes $if statements
 487         work correctly.
 488
 489 Mon Jun 24 20:45:59 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 490
 491         * readline.c: support for displaying key binding information

 501 Thu Apr 25 12:03:49 1991  Brian Fox  (bfox at gnuwest.fsf.org)
 502
 503         * vi_mode.c (rl_vi_fword, fWord, etc.  All functions use
 504         the macro `isident()'.  Fixed movement bug which prevents
 505         continious movement through the text.
 506
 507 Fri Jul 27 16:47:01 1990  Brian Fox  (bfox at gnuwest.fsf.org)

 516 Mon Apr  9 19:55:48 1990  Brian Fox  (bfox at gnuwest.fsf.org)
 517
 518         * readline.c: username_completion_function (); For text passed in
 519         with a leading `~', remember that this could be a filename (after
 520         it is completed).
 521
 522 Thu Apr  5 13:44:24 1990  Brian Fox  (bfox at gnuwest.fsf.org)
 523
 524         * readline.c: rl_search_history (): Correctly handle case of an
 525         unfound search string, but a graceful exit (as with ESC).
 526
 527         * readline.c: rl_restart_output ();  The Apollo passes the address
 528         of the file descriptor to TIOCSTART, not the descriptor itself.
 529
 530 Tue Mar 20 05:38:55 1990  Brian Fox  (bfox at gnuwest.fsf.org)
 531
 532         * readline.c: rl_complete (); second call in a row causes possible
 533         completions to be listed.
 534
 535         * readline.c: rl_redisplay (), added prompt_this_line variable
 536         which is the first character character following \n in prompt.
 537
 538 Sun Mar 11 04:32:03 1990  Brian Fox  (bfox at gnuwest.fsf.org)
 539
 540         * Signals are now supposedly handled inside of SYSV compilation.
 541
 542 Wed Jan 17 19:24:09 1990  Brian Fox  (bfox at sbphy.ucsb.edu)
 543
 544         * history.c: history_expand (); fixed overwriting memory error,
 545         added needed argument to call to get_history_event ().
 546
 547 Thu Jan 11 10:54:04 1990  Brian Fox  (bfox at sbphy.ucsb.edu)
 548
 549         * readline.c: added mark_modified_lines to control the
 550         display of an asterisk on modified history lines.  Also
 551         added a user variable called mark-modified-lines to the
 552         `set' command.
 553
 554 Thu Jan  4 10:38:05 1990  Brian Fox  (bfox at sbphy.ucsb.edu)
 555
 556         * readline.c: start_insert ().  Only use IC if we don't have an im
 557         capability.
 558
 559 Fri Sep  8 09:00:45 1989  Brian Fox  (bfox at aurel)
 560
 561         * readline.c: rl_prep_terminal ().  Only turn on 8th bit
 562           as meta-bit iff the terminal is not using parity.
 563
 564 Sun Sep  3 08:57:40 1989  Brian Fox  (bfox at aurel)
 565
 566         * readline.c: start_insert ().  Uses multiple
 567           insertion call in cases where that makes sense.
 568
 569           rl_insert ().  Read type-ahead buffer for additional
 570           keys that are bound to rl_insert, and insert them
 571           all at once.  Make insertion of single keys given
 572           with an argument much more efficient.
 573
 574 Tue Aug  8 18:13:57 1989  Brian Fox  (bfox at aurel)
 575
 576         * readline.c: Changed handling of EOF.  readline () returns
 577          (char *)EOF or consed string.  The EOF character is read from the
 578          tty, or if the tty doesn't have one, defaults to C-d.
 579
 580         * readline.c: Added support for event driven programs.
 581           rl_event_hook is the address of a function you want called
 582           while Readline is waiting for input.
 583
 584         * readline.c: Cleanup time.  Functions without type declarations
 585           do not use return with a value.
 586
 587         * history.c: history_expand () has new variable which is the
 588           characters to ignore immediately following history_expansion_char.
 589
 590 Sun Jul 16 08:14:00 1989  Brian Fox  (bfox at aurel)
 591
 592         * rl_prep_terminal ()
 593           BSD version turns off C-s, C-q, C-y, C-v.
 594
 595         * readline.c -- rl_prep_terminal ()
 596           SYSV version hacks readline_echoing_p.
 597           BSD version turns on passing of the 8th bit for the duration
 598           of reading the line.
 599
 600 Tue Jul 11 06:25:01 1989  Brian Fox  (bfox at aurel)
 601
 602         * readline.c: new variable rl_tilde_expander.
 603           If non-null, this contains the address of a function to call if
 604           the standard meaning for expanding a tilde fails.  The function is
 605           called with the text sans tilde (as in "foo"), and returns a
 606           malloc()'ed string which is the expansion, or a NULL pointer if
 607           there is no expansion.
 608
 609         * readline.h - new file chardefs.h
 610           Separates things that only readline.c needs from the standard
 611           header file publishing interesting things about readline.
 612
 613         * readline.c:
 614           readline_default_bindings () now looks at terminal chararacters
 615           and binds those as well.
 616
 617 Wed Jun 28 20:20:51 1989  Brian Fox  (bfox at aurel)
 618
 619         * Made readline and history into independent libraries.
 620
