   2
   3         * session.scm (make-fold-modules): Detect circular references in
   4         module graph.  (Thanks to Matthias Köppe.)
   5

   7
   8         * session.scm: Use module (ice-9 regex).

  10
  11 2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  12
  13         * common-list.scm (list*):  Removed, since this function is
  14         implemented as a primitive in libguile/list.c.
  15
  16 2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  17
  18         * session.scm (help): Warn user if 'regex isn't provided.
  19
  20         * Makefile.am (ice9_sources): Removed getopt-gnu-style.scm.
  21
  22         * getopt-gnu-style.scm: Removed deprecated module.
  23
  24 2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  25
  26         * boot-9.scm (make-autoload-interface): Set init value for uses to
  27         '() instead of #f.
  28         (make-modules-in): Name modules with their real (= full) names.
  29         (the-root-module, the-scm-module): Named `(guile)' instead of
  30         `the-root-module'.
  31         (the-scm-module): Set kind to 'interface.
  32
  33         * Makefile.am (ice9_sources): Replaced doc.scm with
  34         documentation.scm.
  35
  36         * session.scm (ice-9): Use module (ice-9 documentation).
  37         (name): Use the name property if everything else fails.
  38         (apropos-fold): New procedure.
  39         (apropos-internal): Re-implement in terms of `apropos-fold'.

  41
  42         * doc.scm: Removed module (ice-9 doc).
  43

  45
  46 2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  47
  48         * doc.scm (documentation-files): Renamed from `doc-files'.
  49         (write-all): Removed.
  50         (find-documentation): Renamed from `documentation'.  Return
  51         documentation string instead of printing it.  Not exported.
  52
  53 2000-06-05  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  54
  55         * boot-9.scm (error-catching-loop): Inform about debugger on error.
  56
  57 2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  58
  59         * boot-9.scm (scm-module-closure): New procedure: Was previously
  60         anonymous.  Now needed in modules.c.
  61         (make-module): Use `standard-eval-closure' to create the eval
  62         closure.
  63
  64 2000-05-14  Gary Houston  <ghouston@arglist.com>
  65
  66         * boot-9.scm (load-user-init): rewritten.  first work out the home
  67         directory and then try to open the file (previously it could try
  68         to open a file in more than one place).  catch exceptions when
  69         trying to get a directory from the user database.  don't check
  70         that ~/.guile is not a directory before trying to load it (a lack
  71         of ~/.guile is not a crime, but if the file is not valid for any
  72         reason then primitive-load will raise an error).
  73
  74 2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  75
  76         * boot-9.scm (abs):  Don't set to magnitude.  abs now does not
  77         accept complex numbers as parameter.
  78
  79 2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
  80
  81         * common-list.scm (delete-if-not!): Bug fix of bug fix: change
  82         label of named let to `delete-if-not'.  Sorry.
  83
  84 2000-05-08  Marius Vollmer  <mvo@zagadka.ping.de>
  85
  86         * common-list.scm (doc fixes): Talk about `true values' instead of
  87         `#t' when a function treats all non-#f valuers the same.
  88         (remove-if-not): Bug fix: call remove-if-not
  89         instead of remove-if when iterating.
  90         (delete-if-not!): Bug fix: call delete-if-not! instead of
  91         delete-if! when iterating.
  92
  93 2000-04-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  94
  95         * r4rs.scm (close-input-port, close-output-port): Removed.
  96
  97 2000-04-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  98
  99         * session.scm (help): New macro.  Prints helpful information.
 100
 101 2000-04-10  Gary Houston  <ghouston@arglist.com>
 102
 103         * popen.scm (open-process): after forking, close all ports except
 104         the end of the pipe to the parent.  otherwise move->fdes and
 105         the exec'd program and the exit handlers can interfere with file
 106         descriptors still in use in parent ports.
 107
 108 2000-04-09  Gary Houston  <ghouston@arglist.com>
 109
 110         * popen.scm (close-process-quietly): new procedure.  use it from
 111         reap-pipes to avoid errors or hanging during background cleanup.
 112
 113 2000-04-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 114
 115         * format.scm (format:obj->str): Handle circular references.  Also,
 116         print improper lists with (x y . z) syntax rather than as
 117         individual pairs.  (This code should probably be integrated into C
 118         level facilities.  It is currently terribly slow.)
 119
 120 2000-04-03  Michael Livshin  <mlivshin@bigfoot.com>
 121
 122         * streams.scm (stream-fold, stream-for-each): don't use named let,
 123         because it prevents the gc from junking the stream argument.
 124
 125 Thu Mar  9 08:05:08 2000  Greg J. Badros  <gjb@cs.washington.edu>
 126
 127         * slib.scm: Back-out change to software-type -- renamed
 128         slib:software-type to software-type, and leave it non-public.
 129
 130 Thu Mar  2 12:20:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
 131
 132         * boot-9.scm: Drop unused definition of sfx function -- thanks
 133         Dirk Hermann!
 134
 135 Wed Mar  1 12:21:02 2000  Greg J. Badros  <gjb@cs.washington.edu>
 136
 137         * streams.scm: Doc patch from Richard Kim, using MIT Scheme as
 138         source of the numerous very short changes.
 139
 140 Sun Feb 13 18:03:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
 141
 142         * slib.scm: Rename software-type to slib:software-type and make it
 143         public.
 144
 145         * r4rs.scm: Added documentation; largely cut and pasted from R4RS
 146         info pages.
 147
 148 Sun Feb 13 17:49:29 2000  Greg J. Badros  <gjb@cs.washington.edu>
 149
 150         * common-list.scm: Added documentation; largely cut and pasted
 151         from slib docs.
 152
 153 2000-02-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 154
 155         * format.scm (format): Reintroduce (define format format:format)
 156         so that the binding in the public interface of the module will be OK.
 157
 158 2000-01-30  Gary Houston  <ghouston@arglist.com>
 159
 160         * boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
 161         to string-append.
 162
 163 2000-01-29  Gary Houston  <ghouston@arglist.com>
 164
 165         * expect.scm (expect): don't call char-ready? before expect-select,
 166         since select now checks port buffers itself.  don't bother to check
 167         the time first either, since expect-select does it.
 168
 169 Thu Jan 20 12:57:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
 170
 171         * format.scm: Use (variable-set! (builtin-variable 'format)) to
 172         re-define format to be format:format (instead of just define,
 173         which interacts poorly with the module system).  Thanks to Shuji
 174         Narazaki for this change.
 175
 176 Tue Jan 11 10:49:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
 177
 178         * boot-9.scm expect.scm, syncase.scm: Switch to new style
 179         `simple-format' message strings: substitute ~A for %s, and ~S for
 180         %S.
 181
 182         * boot-9.scm:  Added (define format simple-format) to expose that
 183         primitive via the simpler name until format.scm is loaded.
 184
 185 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
 186
 187         * boot-9.scm (try-using-libtool-name): Do not bother to look
 188         inside libtool ".la" file, dynamic-link does this for us now.
 189
 190 1999-12-15  Gary Houston  <ghouston@freewire.co.uk>
 191
 192         * slib.scm (library-vicinity, home-vicinity,
 193         scheme-implementation-type, scheme-implemenation-version):
 194         use define-public to export from the module.
 195
 196 Wed Dec 15 08:32:09 1999  Greg J. Badros  <gjb@cs.washington.edu>
 197
 198         * doc.scm: Use `%library-dir' and the other system directories,
 199         not the quickly defuncted `library-dir' that I added before
 200         realizing the former existed.  Thanks Brad Knotwell!
 201
 202 Sun Dec 12 19:18:52 1999  Greg J. Badros  <gjb@cs.washington.edu>
 203
 204         * Makefile.am, doc.scm: Added doc.scm.
 205
 206 1999-12-12 18:54:06 1999  Greg J. Badros  <gjb@cs.washington.edu>
 207
 208         * popen.scm, slib.scm: Added some docstrings for procedures that
 209         were primitives that I encountered in posix.texi.
 210
 211 1999-11-19  Gary Houston  <ghouston@freewire.co.uk>
 212
 213         * Makefile.am (ice9_sources): add arrays.scm.
 214
 215         * boot-9.scm: load arrays.scm if 'array is provided.
 216
 217         * arrays.scm: new file with stuff from boot-9.scm.
 218
 219 1999-11-18  Gary Houston  <ghouston@freewire.co.uk>
 220
 221         * boot-9.scm (read-hash-extend to set up arrays): add 'l' for
 222         long_long uniform vectors.
 223
 224 1999-11-17  Gary Houston  <ghouston@freewire.co.uk>
 225
 226         * networking.scm (sethostent, setnetent, setprotoent, setservent):
 227         take an optional argument STAYOPEN.  default is #f.
 228
 229 1999-10-05  Jim Blandy  <jimb@savonarola.red-bean.com>
 230
 231         * Makefile.in: Deleted from CVS repository.  Run the autogen.sh
 232         script to create generated files like this one.
 233
 234 1999-09-23  Gary Houston  <ghouston@freewire.co.uk>
 235
 236         * boot-9.scm (load-user-init): check that the posix feature is
 237         available before using getpw and getuid.
 238         (top-repl): don't install handlers for SIGINT etc., without posix.
 239         (file-is-directory?): use 'posix instead of i/o-extensions to
 240         check for stat.
 241         (load-user-init): use file-exists? and file-is-directory? to
 242         check for .guile, instead of stat.
 243         (file-is-directory?): don't display the file name if posix not
 244         available.
 245         (feature?): I guess this is deprecated.  redefined using "provided?"
 246         and changed users in boot-9.scm to "provided?".
 247         Conditionally load posix.scm and networking.scm.
 248
 249         posix.scm, networking.scm: new files.  Move definitions from
 250         boot-9.scm if they are only useful with posix/networking available.
 251
 252         * Makefile.am (ice9_sources): add posix.scm, networking.scm.
 253
 254 1999-09-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 255
 256         * debugger.scm (read-and-dispatch-commands): Handle other throws
 257         than 'exit-debugger.
 258
 259         * boot-9.scm (before-signal-stack): New fluid.
 260         (top-repl): Set before-signal-stack in the signal handler.
 261
 262         * debugger.scm (eval-handler): Handle unhandled exceptions.
 263
 264 1999-09-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 265
 266         * debugger.scm ("p"): New alias for "evaluate";
 267         Mark module with :no-backtrace.
 268         ("position"): New command.
 269         (source-position, display-position): New procedures.
 270         (display-source): Display position of expression, if available.
 271         (catch-user-errors): Return #f on error.  (Commands are expected
 272         to return a valid state.)
 273         (read-and-dispatch-command): Bugfix: Return old state on error.
 274
 275 1999-09-16  Jim Blandy  <jimb@savonarola.red-bean.com>
 276
 277         * regex.scm (regexp-substitute/global): Handle the end of the
 278         match list and an empty match list identically.  (Thanks to Greg
 279         Badros.)
 280
 281 1999-09-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 282
 283         * debugger.scm ("evaluate"): Replaced `write-line' with calls to
 284         `write' and `newline' since write-line doesn't write but displays.
 285
 286 1999-09-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 287
 288         * debugger.scm ("evaluate"): Newline after no env announcement.
 289
 290         * debug.scm, emacs.scm: Updated copyright notices.
 291
 292         * boot-9.scm (make-autoload-interface): Bugfix.
 293         (top-repl): Autoload debugger.
 294
 295         * debugger.scm ("backtrace"): Don't pass length param to
 296         display-backtrace if it wasn't explicitly given by the user.
 297         (write-frame-long/application): Also print corresponding source
 298         expression.
 299         ("evaluate"): Evaluate in local environment frame, if existent;
 300         Handle errors.
 301
 302 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 303
 304         * format.scm (format:format-work): Use #\tab and #\page instead of
 305         slib:form-feed and slib:tab.  (Thanks to Ceri Storey.)
 306
 307         * format.scm (format:abort): Call error, not slib:error.
 308
 309 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 310
 311         * boot-9.scm (using-readline?): New procedure: Returns #t if
 312         readline is used by the repl run by this thread.
 313         (handle-system-error): Print "Backtrace:" before backtrace since
 314         this is no longer done by display-backtrace.
 315
 316         * debug.scm (frame-number->index): Optionally take stack as
 317         argument.
 318
 319         * debugger.scm: Use the frame number abstraction which allows for
 320         both forward and backward views of the stack
 321         (write-frame-index-short, write-frame-index-long):
 322         Use selector `frame-number';
 323         (select-frame-absolute): Use frame-number->index.
 324         ("backtrace"): Use builtin backtrace printing.
 325         Use (ice-9 debug).
 326         Use readline conditionally.
 327
 328 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 329
 330         * regex.scm (fold-matches, list-matches): New functions.
 331         (regexp-substitute/global): Rewritten again in terms of
 332         list-matches, to get null match behavior correct.
 333
 334         * regex.scm (regexp-substitute/global): Rewrite so that 'post at
 335         the end of the item list actually causes a tail call.  (Thanks to
 336         Jan Nieuwenhuizen.)
 337
 338 1999-09-11  Marius Vollmer  <mvo@zagadka.ping.de>
 339
 340         * readline.scm: Moved to ../guile-readline.
 341
 342         * boot-9.scm (top-repl): Removed code for activating readline.
 343
 344         * Makefile.am: Removed mention of readline.scm.
 345
 346         * Makefile.in: Regenerated.
 347
 348 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 349
 350         Delete the test which compares the configuration date of libguile
 351         with the configuration date of ice-9.  This test yields too many
 352         false positives to be helpful.  For example, if you build Guile
 353         for several architectures but have them all share a "share"
 354         directory (which is supposed to work), then all but one
 355         architecture's Guile will complain that the configuration dates
 356         don't match.  Which is true, but indicates nothing wrong.
 357         * boot-9.scm: Delete code which compares ice-9-config-stamp with
 358         libguile-config-stamp.
 359         * version.scm.in: Delete.
 360         * Makefile.am (ice9_generated): Delete.
 361         (subpkgdata_DATA): Remove ice9_generated.
 362         (EXTRA_DIST): Remove version.scm.in.
 363         * Makefile.in: Regenerate.
 364
 365 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 366
 367         * debugger.scm: New file: Initial version of the Guile debugger
 368         written by Chris Hanson.  (The debugger isn't finished, but is
 369         included in Guile anyway since it is already quite useful.)
 370
 371         * boot-9.scm (top-repl): Use (ice-9 debug) (ice-9 debugger) (ice-9
 372         session) (ice-9 threads) (ice-9 regex) from guile-user only if
 373         top-repl is called.  This makes startup time for scripts 30% of
 374         what it was before...  Removed redundant code for loading of
 375         readline.
 376
 377         * Makefile.am (ice9_sources): Added debugger.scm.

 382
 383 1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 384
 385         * boot-9.scm: Removed old style hooks.
 386         (inherit-print-state): Rwwritten to use port-with-print-state.
 387
 388 1999-08-20  James Blandy  <jimb@mule.m17n.org>
 389
 390         Remove support for the #/ path list syntax entirely.
 391         * boot-9.scm (read-path-list-notation,
 392         read-path-list-notation-warning): Deleted.
 393         Don't register read-path-list-notation-warning as a reader for
 394         objects starting with '#/'.
 395
 396 1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 397
 398         GOOPS needs the observer protocol specified for the new module
 399         system.  Here's a simple version for the old module system:
 400         * boot-9.scm (module-observers, module-weak-observers,
 401         module-observer-id, set-module-observers!,
 402         set-module-observer-id!): New accessors.
 403         (module-type): Added slots `observers', `weak-observers' and
 404         `observer-id'.
 405         (module-observe, module-observe-weak, module-unobserve,
 406         module-modified): New procedures.
 407         (module-make-local-var!, module-add!, module-remove!,
 408         module-clear!, module-define!, module-use!): Call module-modified.
 409
 410 1999-07-29  Marius Vollmer  <mvo@zagadka.ping.de>
 411
 412         * boot-9.scm (error-catching-loop): Correct non-RnRS usage of internal
 413         defines.
 414
 415 1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>
 416
 417         * streams.scm: New module, contributed by Michael Livshin.
 418         * Makefile.am (ice9_sources): List it.
 419         * Makefile.in: Regenerated.
 420
 421         * boot-9.scm (read-delimited!): Put the terminator in the correct
 422         position.
 423
 424 1999-06-29  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 425
 426         * readline.scm: Bugfix: Avoid getting the continued-lines prompt
 427         at multiple calls to read.
 428         (promtp2): Variable for continued-lines prompt.
 429         (make-readline-port): Use prompt2.
 430         (set-readline-prompt!): New optional arg which sets
 431         continued-lines prompt.
 432
 433         * boot-9.scm (top-repl): Set/clear readline prompts before/after
 434         reading expressions.
 435
 436 1999-06-18  Jim Blandy  <jimb@savonarola.red-bean.com>
 437
 438         * ls.scm (ls, lls): Handle no arguments as meaning to look in
 439         `(current-module)'. (Patch from Thien-Thi Nguyen.)
 440
 441 1999-06-14  Jim Blandy  <jimb@savonarola.red-bean.com>
 442
 443         * string-fun.scm (split-before-predicate, split-after-predicate,
 444         split-discarding-predicate): Make these public.  (Thanks to
 445         Thien-Thi Nguyen.)
 446
 447         1999-06-13  Gary Houston  <ghouston@easynet.co.uk>
 448
 449         * more changes to expect.scm, to avoid the one-character lookhead
 450         that was introduced to fix the $ problem:
 451
 452         * expect.scm (expect): call the match proc an extra time at end
 453         of file and set the eof? argument appropriately.  call
 454         expect-eof-proc only if the last call didn't match.
 455         * expect.scm (expect-strings): change port to eof? in match proc.
 456         * expect.scm (expect-regexec): take an eof indicator as an argument
 457         instead of a port.
 458
 459 1999-06-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 460
 461         * Makefile.am (ice9_sources): Add popen.scm to list.
 462         * Makefile.in: Regenerated.
 463
 464         Fixes for expect from Gary Houston  <ghouston@easynet.co.uk>:
 465
 466         * expect.scm (expect-regexec): define 'eof-next?'.  I don't
 467         know why it was missing.  also don't peek for end of lines
 468         unless expect-strings-exec-flags contains regexp/noteol.
 469         (expect-strings-exec-flags): initialise to regexp/noteol.
 470
 471         Gary Houston's open-buffer port patches:
 472
 473         1999-04-01  Gary Houston  <ghouston@easynet.co.uk>
 474
 475         * popen.scm: applied fixes from Greg Harvey.  use a guardian
 476         and a gc-thunk so that cleanup is done if a pipe is garbage
 477         collected or closed with close-port.  use a weak hash-table instead of
 478         an alist.
 479
 480         1999-03-20  Gary Houston  <ghouston@easynet.co.uk>
 481
 482         * expect.scm (expect): call the match proc with the port instead.
 483         (expect-strings): use peek-char to get the next char.  this has
 484         the advantage of getting the handling of $ "correct", but the
 485         disadvantage of needing to get (and maybe block for) an extra character
 486         from the port when it may not be needed.  hence:
 487         (expect-strings-exec-flags): new variable/parameter, supplies
 488         flags for regexp-exec.  if this includes regexp/noteol, then
 489         automatic regexp/noteol handling (requiring an extra peeked char)
 490         is enabled.  default is regexp/noteol.
 491         (expect-strings-compile-flags): new variable/parameter, supplies
 492         flags for make-regexp.  default is regexp/newline.
 493
 494         1999-03-15  Gary Houston  <ghouston@easynet.co.uk>
 495
 496         * expect.scm (expect): call the match proc with an extra char,
 497         peeked from the stream.
 498         (expect-strings): build a match proc which takes the extra char.
 499         (expect-regexec): take an extra arg "eof-next?" and use it
 500         to decide whether the regexp/noteol flag should be added.
 501
 502         1999-02-26  Gary Houston  <ghouston@easynet.co.uk>
 503
 504         * boot-9.scm (top-repl): don't flush all ports at exit.
 505         (error-catching-loop): likewise.
 506
 507         1998-12-23  Gary Houston  <ghouston@easynet.co.uk>
 508
 509         * boot-9.scm (scm-style-repl): -read: don't call
 510         consume-trailing-whitespace if val is eof object.  Allows
 511         exiting repl with single control-D.
 512
 513         1998-12-06  Gary Houston  <ghouston@easynet.co.uk>
 514
 515         * boot-9.scm (error-catching-loop): don't force output within
 516         error catching loop after quit received.
 517         (top-repl): flush all ports when the repl terminates.
 518
 519         * boot-9.scm (error-catching-loop): flush all ports before
 520         primitive exit if non-interactive.
 521         force-output on current-error-port if interactive.
 522
 523         * boot-9.scm (reopen-file): deleted.
 524         * popen.scm (open-output-pipe, open-input-pipe): moved from
 525         boot-9.scm.
 526         * popen.scm: new file.
 527
 528 1999-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 529
 530        * boot-9.scm (iota):  replaced by a tail recursive version.
 531        (reverse-iota):  removed.
 532
 533 1999-06-03  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 534
 535         * optargs.scm (lambda*): Bugfix: Replaced ARGLIST -->
 536         non-optional-args.  (Thanks to David Lutterkort.)
 537
 538 1999-05-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 539
 540         * string-case.scm: Removed; functions moved to libguile/strop.c
 541         (which could be dynamically linked in the future anyway).
 542         * Makefile.am (ice9_sources): Don't list string-case.scm.
 543         * Makefile.in: Regenerated.
 544         * format.scm: Don't bother importing (ice-9 string-case).
 545
 546 1999-05-02  Jim Blandy  <jimb@savonarola.red-bean.com>
 547
 548         * boot-9.scm (provided?): New function.
 549
 550         * Makefile.am: Add string-case.scm and format.scm to ice9_sources.
 551         * Makefile.in: Regenerated.
 552
 553         * string-case.scm: New file, brought in from SLIB, and adapted to
 554         Guile's module system.
 555
 556         * format.scm: New file, brought in from SLIB, with the following
 557         changes:
 558         (format:format): If the first argument is the format string, stick
 559         a #f on the front of it, so it is now a valid CL format argument
 560         list.  This is easier than changing everyplace else (like the
 561         error formatter) that expects it to be in CL form.  The other
 562         clause which explicitly tests for this case is now dead code.
 563         (format:format-work): Allow `@' and `:' in either order, as per
 564         modern CL behavior.
 565         (format:num->cardinal): Don't assume that an elseless if returns
 566         '() when the condition is false.
 567
 568 1999-04-17  Jim Blandy  <jimb@savonarola.red-bean.com>
 569
 570         * Makefile.in: Regenerated.
 571
 572 1999-04-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 573
 574         * boot-9.scm: Provide 'values.
 575
 576 1999-03-21  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 577
 578         * boot-9.scm (process-define-module, use-syntax): Bugfix:
 579         :use-syntax should add syntax to using module, not current module.
 580         (internal-use-syntax): Removed.
 581
 582 1999-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 583
 584         * session.scm (apropos-internal): Modified to comply with new
 585         argument order for hash-fold.
 586
 587 1999-03-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 588
 589         * boot-9.scm (try-load-module): New procedure.  Broken out from
 590         resolve-module.
 591         (resolve-module): Bugfix: Make it possible for a module at a
 592         deeper level (x y z) to depend on a module on a higher (x y).
 593
 594         This also has the desired side-effect that multiple attempts to
 595         load a module (e.g. with `use-modules') work until source is
 596         actually found for the module (e.g. because the correct catalog
 597         has been added to the load path).
 598
 599         Use try-load-module.
 600
 601 1999-03-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 602
 603         * session.scm (system-module): New procedure.  Used to switch a
 604         module between system and user state.
 605
 606 1999-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 607
 608         * session.scm (apropos-internal): Rewritten using hash-fold.
 609
 610         * emacs.scm, session.scm, slib.scm): Added :no-backtrace in module
 611         definition.
 612
 613 1999-03-14  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 614
 615         * boot-9.scm (make-record-type): Use `set-struct-vtable-name!' to
 616         associate a name to the record type descriptor so that the object
 617         system can create a wrapper class for it.
 618
 619 1999-03-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 620
 621         Improvement of backtraces: Introduces a new stack narrowing
 622         specifier, #t, for the inner cut.  If the inner cut is specified
 623         by #t, `make-stack' will throw away inner stack frames (most
 624         recent calls on call chain) up to but excluding the first user
 625         stack frame encountered.
 626
 627         This specifier is now used in `save-stack' so that the call
 628         `(save-stack)' will get the new behaviour. [It is recommended that
 629         any error reporting functions written by the user have this call
 630         on the outermost expression level (i.e. as a member of the lambda
 631         list).]
 632
 633         Modules are partitioned into "user" and "system" modules. [I know
 634         that some names used here are silly, but I don't have more time to
 635         spend on a better solution, especially considering that the module
 636         system will be replaced.  But if people have better ideas, then
 637         please tell me!]
 638
 639         System modules are created by adding :no-backtrace among the
 640         define-module switches:
 641
 642         (define-module (foo)
 643           :no-backtrace)
 644
 645         Modules which doesn't have the :no-backtrace specifier are user
 646         modules.
 647
 648         A stack frame is classified as a user frame if it has source code
 649         associated with it and if this source code can be proven to come
 650         from a user module.  If it can be proven to come from a system
 651         module it is a system frame.
 652
 653         Frames which can't be classified, e.g. application frames, are cut
 654         away if they occur between system frames, but are left on the
 655         stack if they occur between the last system frame and the first
 656         user frame encountered.  (Note that the first user frame
 657         encountered is the last user code being evaluated!)
 658
 659         In some cases the system part of the call chain is introduced by
 660         frames which should but can't be proven to be system frames.  The
 661         following workaround has been implemented: The cutting proceeds
 662         over application frames where the operator is marked by the
 663         `system-procedure' property.  (This has been used to cut away
 664         generic function dispatch code in the object system.)
 665
 666         * boot-9.scm (set-system-module!): New procedure: Set system/user
 667         status of a module.;
 668         Mark `the-root-module' and `the-scm-module' as system modules.
 669         (process-define-module): Add new keyword :no-backtrace.
 670
 671         * boot-9.scm (environment-module): Bugfixed.
 672         (set-module-eval-closure!): Add a pointer back from the eval
 673         closure to the module.
 674
 675         * emacs.scm (emacs-load): Reset port filename after transfer.
 676

 684
 685 1999-02-15  Jim Blandy  <jimb@savonarola.red-bean.com>
 686
 687         Fix from Russ McManus:
 688         * getopt-long.scm (parse-option-spec): Store 'optional as the
 689         value-required? field for options that take optional values.
 690         (process-short-option): Grab a value for the option when it takes
 691         either an optional or required value.
 692

 716
 717 1999-01-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 718
 719         * slib.scm (install-require-module): Fixed the kludge which loads
 720         the slib catalog: Doesn't anylonger assume that the feature tested
 721         for isn't loaded.
 722
 723 1998-12-14  Jim Blandy  <jimb@zwingli.cygnus.com>

 728
 729         * boot-9.scm (process-define-module): Reverted the change of
 730         1998-11-23 which caused loading of object code if :use-module was
 731         applied to the module itself.
 732
 733 1998-12-11  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 734
 735         * Makefile.am: Removed setf.scm.
 736
 737         * setf.scm: Removed.  1. It was buggy.  2. It was unschemey.

 751         which implements generalized references a la Common LISP.
 752
 753 1998-12-02  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 754
 755         * boot-9.scm (process-define-module): Added new specifier
 756         :autoload MODULENAME BINDINGS to the define-module form.
 757         The autoload specifier tells the module system to load the module
 758         MODULENAME at the first occasion that any variable with its name
 759         among BINDINGS is referenced.
 760         (make-autoload-interface): New procedure:  Constructs a stand-in
 761         for the public interface for the module to be autoloaded.
 762
 763 1998-12-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 764
 765         * boot-9.scm (*suppress-old-style-hook-warning*): Set this to #t
 766         if you don't want the old style hook warnings.
 767
 768 1998-12-01  Christian Lynbech  <chl@tbit.dk>
 769
 770         * boot-9.scm (try-using-libtool-name): Fix check on dlname to make
 771         sure that it isn't empty, as it is when we are only buidling
 772         static libraries.
 773
 774 1998-11-27  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 775
 776         * session.scm (arity): New procedure.
 777
 778 1998-11-26  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 779
 780         * boot-9.scm: Use run-hook instead of run-hooks everywhere.
 781
 782 1998-11-26  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 783
 784         * boot-9.scm (run-hooks, add-hook!, remove-hook!): Added temporary
 785         code for backward compatibility until people have had time to
 786         adapt to the new hooks.
 787
 788 1998-11-23  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 789
 790         * boot-9.scm (beautify-user-module!): Beautify also if public
 791         interface is set to the module itself.  In this way we can use
 792         beautify-user-module! to beautify a module prepared for object
 793         code.
 794         (process-define-module): Special case: Try to load object code as
 795         well if a module does :use-module on itself.
 796
 797         * boot-9.scm: Bugfix: Since boot-9.scm is now loaded from
 798         invoke_main_func, we can no longer be sure that all modules have
 799         been registered when boot-9.scm is loaded.
 800         (register-modules): New function: Register and tag modules
 801         registered by scm_register_module_xxx since last call to this
 802         function.  Modules are tagged with the dynamic object passed as
 803         argument.  (Already linked modules should be tagged with #f.)
 804         (init-dynamic-module, link-dynamic-module): Call register-modules
 805         first to register linked modules.
 806
 807         * boot-9.scm (init-dynamic-module): Remove module from
 808         registered-modules as soon as possible in case we are recursively
 809         invoked; Set public interface before doing the dynamic-call.
 810
 811         * boot-9.scm (map-in-order): Removed (replaced by scm_serial_map).
 812         (abort-hook, before-error-hook, after-error-hook,
 813         before-backtrace-hook, after-backtrace-hook, before-read-hook,
 814         after-read-hook, exit-hook): Make hooks with `make-hook'.
 815
 816         * boot-9.scm: Make hooks first class citizens and make them easier
 817         to use from C:
 818         (make-hook, add-hook!, remove-hook!, run-hooks): Moved to
 819         libguile/feature.c.
 820
 821         * boot-9.scm: Added warnings about bindings used in
 822         libguile/modules.c: the-module, set-current-module,
 823         make-modules-in, beautify-user-module!, module-eval-closure.
 824
 825 1998-11-21  Mikael Djurfeldt  <mdj@kenneth>
 826
 827         * boot-9.scm (the-environment): New special form: Returns an
 828         object representing the current local evaluation environment.
 829         This object can be used in `local-eval' and `defined?'.
 830
 831 1998-11-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 832
 833         * boot-9.scm (collect): New syntax.  Similar to begin but returns
 834         a list of the results of all forms in the sequence instead of the
 835         result of the last form.
 836
 837 1998-11-10  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 838
 839         * boot-9.scm (values, call-with-values): Moved here from
 840         syncase.scm.
 841
 842         * syncase.scm (values, call-with-values): Moved to boot-9.scm.
 843
 844         * boot-9.scm (readline-options, readline-enable, readline.disable,
 845         readline-set!: New options interface.
 846
 847         * readline.scm (readline-port): Use readline-options-interface.
 848
 849 1998-11-05  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 850
 851         * boot-9.scm: Set the repl start module in `top-repl' instead of
 852         at the end of boot-9.scm.
 853
 854 1998-11-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 855
 856         * emacs.scm (format): Bugfix: Handle multiple arguments
 857         correctly.  (Thanks to Thien-Thi Nguyen.)
 858
 859 1998-11-01  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 860
 861         * boot-9.scm (exit-hook): New hook: Is run at the very end of an
 862         interactive session.
 863         (top-repl): Run exit-hook on exit.
 864
 865         * readline.scm (readline-port): Maybe read history; Maybe write
 866         history at exit (add to exit-hook).
 867
 868 Fri Oct 30 15:15:37 1998  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 869
 870         * readline.scm (make-readline-port): Bugfixed last change...
 871
 872 1998-10-28  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 873
 874         * readline.scm (make-readline-port): Don't set prompt to "... " if
 875         read line was empty.
 876
 877 1998-10-19  Jim Blandy  <jimb@zwingli.cygnus.com>
 878
 879         * boot-9.scm, debug.scm, expect.scm, hcons.scm, lineio.scm,
 880         r4rs.scm, slib.scm, threads.scm: Update copyright years.
 881
 882         * getopt-gnu-style.scm, slib.scm: Add copyright notice.
 883
 884         Talked to Stallman.  Actually, the syntax-case copyright is no
 885         problem.  Duh.
 886         * Makefile.am (ice9_sources): Revert last change.
 887         * syncase.scm, psyntax.pp, psyntax.ss: Added again.
 888         * Makefile.in: Regeneretade.
 889
 890         * boot-9.scm: Don't assume that this file is loaded just before
 891         entering a read-eval-print loop.  Turn code to load (ice-9 emacs)
 892         into...
 893         (load-emacs-interface): New function.
 894         (top-repl): Call it, if use-emacs-interface is defined and true.
 895         At this point, we *do* know we're about to enter a REPL.
 896
 897         We can't include Kent Dybvig's syntax-case macro expander in the
 898         core Guile distribution, because we don't have copyright
 899         assignments for this code.  We can certainly distribute them as a
 900         separate package, but Guile should be FSF code.
 901         * syncase.scm, psyntax.pp, psyntax.ss: Removed.
 902         * Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
 903         psyntax.ss.
 904         * Makefile.in: Regenerated.
 905
 906         * Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
 907         * Makefile.in: Regenerated.
 908
 909 1998-10-18  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 910
 911         * boot-9.scm: Added extended read syntax for byte vectors #y(...)
 912         and short vectors #h(...).
 913
 914 1998-10-14  Jim Blandy  <jimb@zwingli.cygnus.com>
 915
 916         * calling.scm (excursion-function-syntax): Use a sequence of
 917         set!'s, not a single multi-variable set!; we removed support for
 918         that syntax a long time ago.  (Thanks to Shuji Narazaki.)
 919
 920 1998-10-12  Jim Blandy  <jimb@zwingli.cygnus.com>
 921
 922         * r4rs.scm (OPEN_READ, OPEN_WRITE, OPEN_BOTH): Don't bother
 923         testing software-type here.  That's the least of our Windows
 924         porting issues, and it's done wrong anyway.
 925
 926 1998-10-09  Jim Blandy  <jimb@zwingli.cygnus.com>
 927
 928         * boot-9.scm (read-path-list-notation-warning): New function:
 929         print a warning the first time we see `#/' notation.
 930
 931         * q.scm (sync-q!, q?, q-remove!, q-push!, enq!): Lots of bugs, and
 932         (eq?  #f '()) assumptions.  Make functions that aren't documented
 933         to return anything else return the queue itself.  (Bug report from
 934         Michael Livshin --- thanks!)
 935
 936 1998-08-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 937
 938         * debug.scm (trace-entry, trace-exit): Removed re-enabling of
 939         trace flag.
 940
 941         * boot-9.scm (make-options): Bugfix: Changed pair? --> list? in
 942         order to allow the empty list as arg.
 943         (error-catching-loop): Use `with-traps' to create a dynamic
 944         context with traps enabled.
 945
 946 1998-08-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 947
 948         * boot-9.scm: Removed (ice-9 regex) from use-list of (guile)
 949         module.
 950         (try-using-libtool-name): Removed dependency on (ice-9 regex).
 951
 952 1998-08-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 953
 954         * boot-9.scm: Make the root module use (ice-9 regex) if
 955         available.  The dynamic linking facilities in boot-9.scm are
 956         currently dependent upon regular expressions.  My change of
 957         1998-07-14 removed (ice-9 regex) from the use-list of the root
 958         module and thereby destroyed dynamic linking.
 959
 960 1998-07-29  Jim Blandy  <jimb@zwingli.cygnus.com>
 961
 962         * Makefile.in: Regenerated using the last public version of
 963         automake, not the hacked Cygnus version.
 964
 965 1998-07-28  Jim Blandy  <jimb@zwingli.cygnus.com>
 966
 967         * Makefile.in: Regenerated, after removing Totoro kludge.
 968
 969 1998-07-28  Jim Blandy  <jimb@totoro.red-bean.com>
 970
 971         * getopt-gnu-style.scm: New file.  (Thanks to Russ McManus.)
 972
 973 1998-07-26  Jim Blandy  <jimb@zwingli.cygnus.com>
 974
 975         * Makefile.in Rebuilt, for config changes in parent dir.
 976
 977 1998-07-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 978
 979         * readline.scm (make-readline-port): Set prompt string to "... "
 980         after first read line.  (Thanks to Richard Polton.)
 981
 982 1998-07-19  Jim Blandy  <jimb@zwingli.cygnus.com>
 983
 984         * lineio.scm (make-line-buffering-input-port): Don't use
 985         ungetc-char-ready?, since we don't provide that function any
 986         more.  The unread-string function doesn't interact properly with
 987         any of the standard I/O functions anyway.  (Thanks to Andrew
 988         Archibald.)
 989
 990         * hcons.scm (hashq-cons-assoc): Don't assume the empty list is
 991         false.  Return false when we cannot find a matching entry in the
 992         list.  (Thanks to Andrew Archibald.)
 993
 994 1998-07-16  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 995
 996         * boot-9.scm (export, export-syntax): New special forms: Export
 997         bindings from a module.  `(export name1 name2 ...)' can be used at
 998         the top of a module (after `define-module') to specify which names
 999         should be exported.  It can be used as an alternative to
1000         `define-public'.  `export-syntax' works equivalently to `export'
1001         but is intended for export of syntactic keywords.
1002         (Thanks to Thien-Thi Nguyen.)
1003
1004 1998-07-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1005
1006         * boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.
1007
1008 1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1009
1010         * boot-9.scm: Let the user start in module `(guile-repl)' instead
1011         of module `(guile)'.  Also make sure that `(guile-repl)' uses
1012         suitable modules.  This change improves Guile stability
1013         substantially since bindings will only be copied from the root
1014         module: If the user redefines builtins in `(guile-repl)' it won't
1015         affect the internal operation of Guile itself.
1016
1017 1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1018
1019         * boot-9.scm (load-module): When loading files from within files
1020         themselves being loaded: Use the directory path of the file being
1021         loaded as root for relative filenames.  (After suggestion by
1022         Steven G. Johnson.)
1023
1024 1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1025
1026         * emacs.scm (emacs-load): New feature: Eval in specified module.
1027
1028 1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1029
1030         * readline.scm: Typo in regex module name.
1031
1032 1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1033
1034         * readline.scm (apropos-completion-function): regexp-quote text to
1035         be completed.
1036
1037 1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1038
1039         * debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.
1040
1041 1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1042
1043         * boot-9.scm: Check that (current-input-port) is a tty before
1044         enabling readline.  (Thanks to Michael N. Livshin.)
1045
1046 1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1047
1048         * boot-9.scm (use-syntax): Turned into a macro inorder to be
1049         similar in use to `use-modules'.
1050         Example: (use-syntax (ice-9 syncase)) will 1. load the module
1051         (ice-9 syncase), and, 2. install the procedure `syncase' as eval
1052         transformer.
1053         (internal-use-syntax): New procedure.
1054         (process-define-module): Use `internal-use-syntax'.
1055
1056 1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1057
1058         * Makefile.am (ice9_sources): Add emacs.scm.
1059
1060 1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1061
1062         * readline.scm: Use the new readline facilities: Add the
1063         possibility to control input and output ports; Add apropos
1064         completion.
1065
1066         * boot-9.scm: Antirevert Jim's readline code which he reverted
1067         19971027 and adapt it to the current readline interface.
1068
1069         * boot-9.scm (top-repl): Only enable readline if not using the
1070         Emacs interface; Only use repl prompt when using the readline port
1071         from repl-read.  (We don't want to see it when calling `read'.)
1072
1073         * boot-9.scm (remove-hook!): Parenthesis bug.
1074
1075 1998-05-11  Mikael Djurfeldt  <mdj@kenneth>
1076
1077         * boot-9.scm: Load readline module if readline is present.
1078
1079         * readline.scm (apropos-completion-function): New procedure:
1080         Symbolic completion.  (Thanks to Andrew Archibald!)
1081
1082 1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1083
1084         * boot-9.scm (process-define-module): Added keyword use-syntax.
1085
1086 1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1087
1088         * nonblocking.scm: Removed.  libguile is now inherently
1089         nonblocking through the use of scm_internal_select.
1090
1091         * emacs.scm: Removed use of nonblocking.scm.
1092
1093         * gwish.scm, gtcl.scm: Removed.  tcltk.scm has made these
1094         obsolete.
1095
1096 1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>
1097
1098         * runq.scm (runq-control): Corrected spelling of enqueue!.
1099         (Thanks to Karl M. Hegbloom.)
1100
1101 1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>
1102
1103         * boot-9.scm: Added new run-time option interface eval-options.
1104
1105 1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1106
1107         * boot-9.scm (remove-hook!): New macro.  (Thanks to Maciej
1108         Stachowiak.)
1109
1110 1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1111
1112         * threads.scm: Added simple error and signal handler.
1113         (make-thread, begin-handler): Use this handler.  The most
1114         important effect of this is that signals get unmasked.
1115         Previously, when a signal was thrown signals remained masked
1116         (signals get masked when a signal is taken) which influenced other
1117         threads.

1120
1121         A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
1122         * slib.scm (identity): Unmake public.
1123         (slib:eval): Evaluate inside `slib-module'.
1124
1125 1997-12-24  Tim Pierce  <twp@skepsis.com>
1126
1127         * boot-9.scm: Doc fix.
1128
1129         * slib.scm (identity): Made public.
1130         (home-vicinity): New function (from SLIB/Template.scm).
1131
1132 1997-12-13  Tim Pierce  <twp@skepsis.com>
1133
1134         * boot-9.scm (read-line): Rewritten to call %read-line for
1135         improved speed.  Minor user-visible changes: the new functions are
1136         hardwired to treat the LFD character as signifying end-of-line, so
1137         changing `scm-line-incrementors' will no longer affect the
1138         behavior of read-line.  On platforms which do not represent
1139         end-of-line with a LFD character, read-line should behave more
1140         like native line-processing facilities, but there is still a ways
1141         to go here.
1142
1143 Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>
1144
1145         * boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
1146         is now a fluid.
1147
1148 1997-11-28  Tim Pierce  <twp@skepsis.com>
1149
1150         * boot-9.scm (find-and-link-dynamic-module): If a module directory
1151         contains a .la file (a libtool support file), attempt to extract
1152         the shared library name from that file.  If the .la file does not
1153         exist, try to link against a .so file.  Libtool-generated compiled
1154         modules should load more cleanly in Guile now.
1155         (try-using-libtool-name, try-using-sharlib-name): New functions.
1156
1157 Sun Nov  9 06:10:59 1997  Gary Houston  <ghouston@actrix.gen.nz>
1158
1159         * boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
1160         usefully so they will work from a script.
1161
1162 1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>
1163
1164         * boot-9.scm (inherit-print-state): Moved definition to the
1165         neighborhood of the record code.
1166
1167 Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1168
1169         * boot-9.scm: Revert changes to this file from Oct 23.  It turns
1170         out to interact badly with the Emacs support and the Tcl/Tk
1171         support.  It's not a high enough priority at the moment to be
1172         worth fixing.  I'm leaving the other readline support in, though.
1173
1174 Sat Oct 25 14:23:22 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1175
1176         * Makefile.am: Include readline.scm in the list of files to be
1177         installed, so Guile can find it for interactive use.
1178         * Makefile.in: Regenerated.
1179
1180 Thu Oct 23 01:00:33 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1181
1182         Add support for readline function.
1183         * readline.scm: New module.
1184         * boot-9.scm (repl-reader): New function.
1185         (scm-style-repl): Call repl-reader, instead of doing the reading
1186         ourselves.  Remove repl-report-reset; it was never used for
1187         anything.
1188         (top-repl): If we've got the readline primitives, then redefine
1189         repl-reader to use them.
1190         If we've got the readline primitives, import the readline module.
1191
1192         * ls.scm (ls, lls): Don't assume (eq? #f '()).
1193
1194 Wed Oct 22 18:26:57 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1195
1196         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1197         string-fun.scm: Added copyright notices; reformatted.
1198
1199 Thu Oct  9 05:44:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1200
1201         * expect.scm: (expect-regexec): new procedure, use it in
1202         expect-strings to fix the => syntax under the new regex system.
1203         (top): include regex module in define-module statement.
1204
1205 Wed Oct  8 03:16:01 1997  Gary Houston  <ghouston@actrix.gen.nz>
1206
1207         * (error-catching-loop): new local variable "interactive".  if
1208         #f, abort terminates the process.
1209         (set-batch-mode?!, batch-mode?): new closures, defined in
1210         error-catching-loop.  the names are from scsh.
1211
1212 1997-10-06  Marius Vollmer  <mvo@zagadka.ping.de>
1213
1214         * boot-9.scm (inherit-print-state): If NEW-PORT contains a
1215         print-state, throw it away.
1216
1217 Fri Oct  3 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
1218
1219         * boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
1220         `0'.
1221
1222 Thu Oct  2 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
1223
1224         * boot-9.scm (struct-printer, make-struct-printer,
1225         set-struct-printer-in-vtable!, *struct-printer*): Removed.
1226         (record-type-vtable, make-record-type): Don't use make-struct-printer.
1227         (record-type-vtable): User fields "prpr" (printer is no longer a
1228         user field).
1229         (record-type-name, record-type-fields): Decreased slot index by
1230         one; Use `vtable-offset-user'.
1231
1232 Thu Oct  2 12:00:00  Marius Vollmer  <mvo@zagadka.ping.de>
1233
1234         * boot-9.scm (inherit-print-state): New experimental function.
1235
1236 Tue Sep 30 13:12:48 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1237
1238         Suggestion and script from Maciej Stachowiak:
1239         * boot-9.scm: Split off modules into separate, autoloadable files.
1240         This reduces startup time from 10.5s to 5.5s (user cpu).
1241         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1242         string-fun.scm: New files, containing stuff that used to be in
1243         boot-9.scm.
1244         * Makefile.am (ice9_sources): List new files here, for
1245         distribution and installation.
1246         * Makefile.in: Regenerated.

1249
1250         * Makefile.in: Regenerated with automake 1.2c.
1251
1252 Mon Sep 29 03:21:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1253
1254         * slib.scm (slib:load): slib:load first tries to load the file
1255         named NAME, then NAME.scm.  On error, report the error occuring at
1256         the first attempt (NAME) rather than the second (NAME.scm).
1257
1258         * boot-9.scm: Bugfix: Hard-solder the print-option procedure into
1259         the make-options macro so that we needn't refer to a global
1260         symbol.
1261
1262 Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1263
1264         * debug.scm: Moved options interface procedures to boot-9.scm.
1265

1269
1270         * boot-9.scm (separate-fields-discarding-char,
1271         separate-fields-after-char, separate-fields-before-char): Call
1272         continuation function, RET, as advertised: with each separated
1273         field a separate argument.
1274
1275         * Makefile.in: Regenerated with automake 1.2a.
1276
1277 Sat Sep 20 14:23:53 1997  Mikael Djurfeldt  <mdj@kenneth>
1278
1279         * slib.scm (slib:load): Export.
1280
1281         * boot-9.scm (in-vicinity): Bugfix: Don't add "/" to an empty
1282         vicinity;
1283         Provide defmacro.
1284
1285 Thu Sep 18 01:24:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1286

1290
1291         * boot-9.scm (keyword->symbol, display-usage-report): Changed
1292         length --> string-length.  (Thanks to Aleksandar Bakic.)
1293         (separate-fields-discarding-char, separate-fields-after-char,
1294         separate-fields-before-char): Bugfix from Maciej Stachowiak
1295         <mstachow@mit.edu>.  Thanks!
1296         (try-module-linked): Try to find module among those already
1297         registered.
1298         (try-module-dynamic-link): Removed the first test which
1299         corresponds to a call to `try-module-linked'.
1300         (resolve-module): Resolve modules in this order: 1. Already
1301         registered modules (for example those which have been statically
1302         linked), 2. Try to autoload an .scm-file, 3. Try to dynamically
1303         link a .so-file.

1311         * session.scm (name): New procedure: Gives name of object.
1312         (source): New procedure: Gives source of object.

1315
1316         * boot-9.scm (primitive-macro?): New procedure.
1317
1318         * slib.scm: Added hack which transfers syntactic information from
1319         the builtin variable `define' to the slib version if module (ice-9
1320         syncase) has been loaded.  This is necessary to get correct
1321         expansion inside the slib module.
1322
1323         * psyntax.ss (build-let, build-named-let): New output
1324         constructors.

1330         (sc-expand3): New procedure: Expander which takes optional mode
1331         and eval-syntactic-expanders-when arguments.
1332
1333         * syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
1334         Should be used inside the (ice-9 syncase) module with (use-syntax
1335         syncase) and with the current directory containing the psyntax.ss
1336         source.
1337         Added hack to transfer syntactic information from the builtin
1338         variable `define' to the slib version if module (ice-9 slib) has
1339         been loaded.
1340
1341 Fri Sep  5 05:47:36 1997  Mikael Djurfeldt  <mdj@faun.nada.kth.se>
1342
1343         * syncase.scm (sc-interface, sc-expand): Removed hook setup.
1344         (syncase): Publish syntax transformer to be used with
1345         `use-syntax'.
1346         (sc-macro): Use this as the value when publishing macros.
1347
1348         * boot-9.scm (module-type): Added `transformer'.

1350         (module-transformer, set-module-transformer!): Selector and
1351         mutator for module-associated transformer.
1352         (set-current-module): Use module-transformer to set
1353         `scm:eval-transformer'.
1354         (module-use!): Previous change reverted.
1355         (use-syntax): New function: Install a transformer in current
1356         module.
1357         (sc-interface, sc-expand): Removed! :)
1358
1359 Fri Sep  5 03:09:09 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1360
1361         * emacs.scm (emacs-load): Added new parameter `module'.
1362
1363         * syncase.scm (putprop, getprop): Modified to use the object
1364         properties of the variable object corresponding to the symbol;
1365         This way we can ride on the mechanisms of the module system.
1366         Changed `builtin-variable' calls to `define-public' calls.
1367         Setup the hooks sc-expand and sc-interface.
1368
1369         * boot-9.scm (sc-interface, sc-expand): New builtin variables.
1370         (set-current-module): Switch to and from sc-expand as
1371         scm:eval-transformer when going into and out of modules using
1372         syncase macros.
1373         (module-use!): Set scm:eval-transformer to sc-expand when adding
1374         the syncase interface.
1375
1376 Thu Sep  4 14:57:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1377
1378         * syncase.scm (putprop): Temporary fix which publishes new syntax
1379         globally (the old behaviour was complex and connected to the inner
1380         workings of the current module system).
1381
1382 Wed Sep  3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1383
1384         * psyntax.ss: Updated.
1385         psyntax.pp: Bugfix: Previous version had some leading "t":s cut
1386         off!
1387
1388 Tue Sep  2 00:26:42 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

1393
1394 Mon Sep  1 20:08:32 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1395
1396         * gtcl.scm (make-tcl-binder): Rewritten to choose bindings
1397         according to the following priorities:
1398         1. tcl bindings which are present in override-scheme-list
1399         2. bindings from the-scm-module
1400         3. tcl bindings
1401         This way the gtcl module can occur first in the use-list without
1402         disabling the scheme interpreter.
1403         (new-interpreter): New function.
1404
1405         * gwish.scm: Moved initialization code for the-interpreter to
1406         gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
1407         it; Call `new-interpreter'; Don't :use-module (guile).

1418

1424
1425         * session.scm (apropos-internal): Musn't initialize symbol
1426         accumulator with a constant pair.  That led to mutation of the
1427         source!
1428
1429 Sun Aug 24 01:03:10 1997  Mikael Djurfeldt  <mdj@kenneth>
1430
1431         * session.scm (vector-for-each): Removed.

1434         symbols matching regexp.
1435
1436         * debug.scm (frame-number->index): New function.  Convert frame
1437         number (as displayed in the backtrace) to frame index (to be used
1438         in stack-ref).
1439
1440         * emacs.scm (emacs-load): New arguments: interactivep: when
1441         non-false, send back results to Emacs; colnum: Column number;
1442         Use modules (ice-9 debug) and (ice-9 session);
1443         (no-stack, no-source): New simple-actions;
1444         (result-to-emacs): New procedure. Sends data to Emacs via the
1445         result protocol;
1446         (get-frame-source, emacs-select-frame, emacs-frame-eval,
1447         emacs-symdoc): New procedures.

1460
1461         * syncase.scm: Don't tamper with debug mode setting when enabling
1462         macros.  Instead cut the stack with start-stack.
1463         Load psyntax.pp with recording of positions turned off.
1464
1465         * psyntax.pp, psyntax.ss (quasiquote): Changed fx= --> =.
1466
1467         * syncase.scm: New file: Guile-adaption for syntax-case macros.
1468         * psyntax.pp, psyntax.ss: Syntax-case macros, portable version 2 by
1469         R. Kent Dybvig, Oscar Waddell, Bob Hieb and Carl Bruggeman

1482
1483         * emacs.scm (emacs-load): Something has changed in the reader so
1484         that we now should set the port line count to the specified value
1485         (linum) instead of (- linum 1).
1486
1487         * slib.scm (slib:load): Use load-from-path instead of
1488         primitive-load-path so that backtraces get narrowed properly at
1489         the top.
1490
1491         * boot-9.scm (top-repl): Save stack already in signal handler in
1492         order to narrow it correctly.
1493         (save-stack): Adjust narrowing tag for the top of load-stacks.

1505
1506         * boot-9.scm (with-fluids): New macro to go with the
1507         builtin `with-fluids*'.
1508
1509 Thu Jul 24 04:28:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1510
1511         * slib.scm (install-require-module): In newer versions of slib
1512         *catalog* is #f until the first access.  Therefore we call
1513         require:provided? for a random feature if *catalog* is #f.
1514
1515 Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1516
1517         * boot-9.scm: If using emacs interface, enable backtraces
1518         automatically.

1521
1522         * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
1523         dup, fdes->inport, fdes->outport, port->fdes): new procedures.
1524         (duplicate-port): was a C primitive, now it's here.
1525         (move->fdes): allow the first argument to be a file descriptor.
1526         Return the modified port or file descriptor (was unspecified.)
1527
1528 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
1529
1530         Changes to compile under gnu-win32, from Marcus Daniels:
1531         * boot-9.scm (load-user-init): If HOME is unset, provide
1532         a default of /.
1533
1534         * boot-9.scm (define-public): Changed to accomodate Hobbit.
1535
1536 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
1537
1538         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
1539         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
1540         notation, instead of #/ notation.
1541

1543         make-regexp.
1544
1545 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
1546
1547         Fix inconsistencies in parsing of #/ style lists.
1548         * boot-9.scm (read-path-list-notation): New function.
1549         (parse-path-symbol): Deleted.  Replaced by above.
1550         Plug in read-path-list-notation as the parser for #/ lists,
1551         instead of the anonymous lambda form calling parse-path-symbol.
1552         (Thanks to Maurizio Vitale.)
1553
1554         * boot-9.scm (make-list): Remove the definition of this function
1555         from the (ice-9 common-list) module; make the `init' argument
1556         optional in the scm module's definition, to match the deleted
1557         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
1558
1559 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
1560
1561         Try to detect when people are using one version of libguile and a
1562         different version of ice-9.  People have been skewing things and
1563         sending in bug reports.
1564         * version.scm.in: New file, which the configure script munges to
1565         produce version.scm, which contains the ice-9 config stamp.
1566         * boot-9.scm: Compare the libguile and ice-9 config stamps;
1567         display a warning if the two are different.
1568         * Makefile.am: Install version.scm, but don't distribute it.
1569         Distribute version.scm.in, but don't install it.
1570         * Makefile.in: Regenerated.
1571
1572 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
1573
1574         * slib.scm (slib:warn): Alias for WARN function.
1575
1576 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
1577
1578         * boot-9.scm (struct-printer): Fix off-by-one error in range
1579         check.  Correctly check for struct printer tag.
1580
1581         * expect.scm: Turn this into a module, (ice-9 expect).
1582         (expect-port, expect-timeout, expect-timeout-proc,
1583         expect-eof-proc, expect-char-proc, expect, expect-strings,
1584         expect-select): Make these public definitions.
1585         (expect-strings): Use make-regexp and regexp-exec, instead of
1586         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
1587         that's okay.
1588
1589         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
1590         users in the core, and relies on mildly hairy details of the old
1591         regexp interface.
1592
1593         * test.scm: Re-enable tests asserting that '() is true, and not a
1594         boolean.  This stuff has been true for a while.
1595
1596         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
1597         function names.
1598
1599         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
1600         fixes.
1601
1602 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
1603
1604         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1605         ../configure.in.
1606
1607 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1608
1609         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
1610         vtable and not the one of the struct.
1611
1612 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1613
1614         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
1615         make-struct-printer, set-struct-printer-in-vtable!): New bindings
1616         to support printing of structures.
1617         (record-type-vtable, make-record-type): Add slot to hold printing
1618         function and initialize it with something appropriate.  Removed
1619         commented out printing code.
1620         (record-type-name, record-type-fields): Adjusted slot offsets.
1621         (%print-module): Reduce argument list to "mod" and "port".
1622
1623 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1624
1625         * slib.scm (identity): New function, used by SLIB.
1626
1627 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
1628
1629         * boot-9.scm: signal-handler, alarm-thunk: removed.
1630         don't define ticks-interrupt etc.
1631         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
1632         during call to scm-style-repl.
1633
1634 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
1635
1636         * slib.scm (slib:load): Use primitive-load-path instead of
1637         basic-load.  This is probably wrong, but hopefully the entire
1638         source access system will be revised soon anyway, and this will
1639         make require behave more like Emacs Lisp's require.  If this
1640         breaks something, please let me know.  Maybe this is real dumb.
1641
1642 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
1643
1644         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
1645         * boot-9.scm: If the `regex' feature is present, use the module
1646         (ice-9 regex).
1647
1648 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
1649
1650         * regex.scm: New file.
1651         * Makefile.am (subpkgdata_DATA): Add regex.scm.
1652         * Makefile.in: Regenerated.
1653
1654 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1655
1656         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,

1664         in 1997.
1665
1666 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
1667
1668         * expect.scm: use gettimeofday instead of get-internal-real-time
1669         and use a floating point timeout when calling select.  Untested,
1670         since the regex library is currently AWOL.
1671
1672 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
1673
1674         * boot-9.scm (eval-string): Function deleted; it was already
1675         implemented in C, so there's no point in making a divergable copy
1676         here.
1677
1678 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
1679
1680         * Makefile.in: Regenerated, using automake-1.1p.
1681

1687
1688         * boot-9.scm (error-catching-loop): don't read a line from
1689         current input when quit is encountered, the previous change
1690         fixes this too.
1691
1692 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
1693
1694         * boot-9.scm (scm-style-repl): After reading an expression,
1695         consume any trailing newline (perhaps preceded by whitespace), to
1696         avoid screwing up GDB.  More detail in comments.
1697
1698 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
1699
1700         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
1701         the Scheme code like code yet.
1702         * Makefile.in: Resrac,husrched.
1703
1704 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1705
1706         * boot-9.scm (link-dynamic-module): Do not catch errors from
1707         dynamic-link and dynamic-call.  When the shared library exists it
1708         is now assumed to be suitable for a dynamic C module.
1709
1710 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1711
1712         * boot-9.scm (process-use-modules): New function to support the
1713         use-modules macro
1714         (use-modules): throw an error iff one of the requested modules
1715         can't be found.
1716
1717 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
1718
1719         * boot-9.scm: don't define timer-thunk or gc-thunk.
1720
1721 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
1722
1723         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1724
1725         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
1726         we're not using AM_INIT_GUILE_MODULE any more.
1727         * Makefile.in: Regeneratitetedrerd.
1728

1736         no plugins.
1737         * configure.in, configure: Removed.
1738         * Makefile.in: Regenerated.

1749 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
1750
1751         * expect.scm (expect-select): correct the millisecond timeout
1752         arithmetic (from Marko.Kohtala@ntc.nokia.com).

1755
1756         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
1757         instead of in libguile.
1758         (tm:sec etc.) new accessors for broken-down time.
1759         (set-tm:sec etc.) new setters for broken-down time.
1760
1761 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1762

1764         procedures.

1768 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
1769
1770         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
1771         sockaddr:port): new functions.
1772
1773 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
1774
1775         * boot-9.scm: define accessor procedures for the objects returned
1776         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
1777         passwd:name, where the first component is the name of the C structure
1778         and the second is the unprefixed C member name.)
1779
1780 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
1781
1782         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
1783         setservent): no longer take an argument, it was bogus.
1784

1792         keywords and symbols.
1793

1799         Don't define read-sharp.
1800
1801         * boot-9.scm: use read-hash-extend to install extra read syntax.
1802         (read-sharp): removed.
1803         Adjust usage of primitive-load-path, read, which no longer take
1804         case_i or read-sharp arguments.
1805
1806 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1807
1808         * boot-9.scm: Added loading of session support module.
1809
1810         * debug.scm: Removed `display-application'.  (Replaced by
1811         primitive procedure.)
1812
1813         * boot-9.scm (beautify-user-module!): Don't add the root module
1814         interface to the end of the use-list of the root module.
1815
1816 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
1817
1818         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
1819
1820 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
1821
1822         * boot-9.scm: check use-emacs-interface for emacs support.
1823
1824 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
1825
1826         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
1827         read gets EOF.
1828         * (exit): alias for quit.
1829
1830 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
1831
1832         * boot-9.scm (error-catching-loop thunk): use a status variable to
1833         return the quit args.
1834         (scm-style-repl): call -quit, passing return value from
1835         error-catching-repl.  Make -quit return its args.
1836         stand-alone-repl: comment out, since it seems unused.
1837
1838         (error-catching-loop thunk): discard trailing junk after a (quit).
1839
1840 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1841
1842         * boot-9.scm: Removed the old printer code.
1843
1844         * r4rs.scm (apply, call-with-current-continuation): Added comment
1845         explaining why apply and call/cc need to be closures.
1846
1847         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
1848         Removed. These definitions are already present in r4rs.scm.
1849
1850         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
1851         stack before printing traced frames; Re-enable trace flag at end
1852         of handlers.
1853
1854 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1855
1856         * debug.scm: Add hook for reset of trace level at abort.
1857
1858         * boot-9.scm (run-hooks): New procedure.
1859         (add-hooks!): New macro.
1860         Change hooks to use these functions.
1861
1862         * debug.scm: *Warning* This feature is a bit premature.  I add
1863         it anyway because 1. it is very useful, and, 2. you can start
1864         making it less premature by complaining to me and by modifying
1865         the source! :-)
1866         (trace): Given one or more procedure objects, trace each one.
1867         Given no arguments, show all traced procedures.
1868         (untrace): Given one or more procedure objects, untrace each one.
1869         Given no arguments, untrace all traced procedures.  The tracing in
1870         Guile have an advantage to most other systems: We don't create new
1871         procedure objects, but mark the procedure objects themselves.
1872         This means that also anonymous and internal procedures can be
1873         traced.
1874
1875         * boot-9.scm (error-catching-loop): Added handling of apply-frame
1876         and exit-frame exceptions.
1877
1878         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
1879         (set-repl-prompt!): Setter for repl prompt.
1880         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
1881         string, display it; if prompt is a thunk, call it and display its
1882         result; otherwise display "> ".
1883         (Change suggested by Roland Orre <orre@nada.kth.se>.)
1884
1885         * r4rs.scm (%load-verbosely): Reverted change to
1886         `module-defined?', since the module system isn't bootstrapped when
1887         we load r4rs.scm.  This is just a temporary fix to make the
1888         repository version runnable.
1889
1890 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1891
1892         * boot-9.scm: Removed the enabling of debug evaluator and
1893         recording of source code positions.  This was placed there for our
1894         convenience, but it has already sneaked into the distribution
1895         once... so we'd better add this in our local copies instead when
1896         we need it.  (These options are normally enabled at the end of
1897         boot-9.scm when loading the debug module.)
1898
1899 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1900
1901         * boot-9.scm (module-defined?): New function.
1902         (macroexpand-1, macroexpand): Use local-ref instead of defined?
1903         and eval.
1904         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
1905         "defined?".
1906         * slib.scm (defined?): New function to take the place of the
1907         builtin "defined?".  It allways examines the slib module.
1908
1909 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1910
1911         * configure.in: Added AM_MAINTAINER_MODE
1912
1913 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
1914
1915         * boot-9.scm (read-sharp): define directly, don't go through a
1916         %read-sharp layer.
1917
1918 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
1919
1920         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
1921         uniform-vector-set1! which doesn't exist.
1922
1923 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
1924
1925         * boot-9.scm (backtrace): Removed.  (A C version now exists in
1926         backtrace.c.)
1927
1928 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
1929
1930         * boot-9.scm (read-line!, read-delimited!, read-delimited,
1931         read-line): new procedures, see libguile/ChangeLog.
1932
1933 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1934
1935         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
1936
1937         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
1938         init-dynamic-module, dynamic-maybe-call,
1939         find-and-link-dynamic-module, link-dynamic-module,
1940         try-module-dynamic-link, registered-modules): New definitions for
1941         dynamic linking of modules.
1942         (resolve-module): Try to dynamically link the requested module
1943         after failing to load it as Scheme code.
1944
1945 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
1946
1947         * boot-9.scm (getservbyport, getservbyname): remove stray %.
1948
1949 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
1950
1951         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
1952         that's what it is.
1953
1954         * lineio.scm (make-line-buffering-input-port): Properly test for
1955         the case of an empty buffer list.  The old code assumed that '()
1956         was false.
1957
1958 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
1959
1960         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
1961         (use-modules <module name> ...) Put the the modules named by
1962         <module name> ... on the use list of the current module.
1963
1964 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
1965
1966         * boot-9.scm (error-catching-loop): Remove message saying that
1967         typing "$" will put you in the debugger.  This isn't implemented
1968         yet.
1969
1970 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
1971
1972         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
1973         been fixed, so this function is superfluous.
1974         (transform-usage-lambda): Use delq!, not delq-all!.
1975
1976 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
1977
1978         * boot-9.scm (resolve-module): New optional parameter that
1979         controls whether autoloading is attempted or not. Default is #t.
1980         (process-define-module): Don't autoload the defined module.
1981         (try-module-autoload): Don't autoload the directory modules.
1982
1983         * boot-9.scm (process-define-module): Ensure that the-scm-module
1984         is last in the `uses' list to allow shadowing builtin
1985         bindings. All :use-module options are added in the order they
1986         appear in the arguments but before anything already on the list
1987         (such as the-scm-module).
1988
1989 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
1990
1991         * slib.scm (slib-parent-dir): throw error if #f returned from
1992         %search-load-path.
1993
1994 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
1995
1996         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
1997         * Makefile.am, aclocal.m4: New files.
1998         * configure.in: Updated for Automake.
1999
2000 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
2001
2002         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
2003         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
2004         function, use it accordingly.
2005
2006 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
2007
2008         It's an "eval closure", not an "eval thunk."  A thunk is a
2009         function of no arguments.
2010         * boot-9.scm (module-type): Rename module field.
2011         (make-module, eval-in-module, make-root-module,
2012         set-current-module): Uses changed.
2013         (module-eval-closure, set-module-eval-closure!,
2014         root-module-closure): Renamed from module-eval-thunk,
2015         set-module-eval-thunk!, root-module-thunk.
2016         (set-current-module): Change uses of *top-level-lookup-thunk* to
2017         *top-level-eval-closure*.
2018
2019 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2020
2021         * slib.scm (slib-parent-dir): Use string-length, not length.
2022         (Thanks to Bernard Urban.)
2023
2024 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2025
2026         * boot-9.scm: The debugging evaluator and recording of positions
2027         aren't enabled by default any longer (they are switched on in
2028         debug.scm).  But during development we want to have them also
2029         *inside* boot-9.scm.  Therefore, two lines are added at the
2030         beginning of boot-9.scm to enable these.
2031
2032         Call `provide' so that `records' are included among the
2033         `*features*'.
2034
2035         The scheme for saving the stack has been adjusted: save-stack is
2036         now commonly available for saving the stack.  Calling `save-stack'
2037         sets a flag `stack-saved?' which prevents overwriting the stack.
2038         `stack-saved?' is reset at `abort'.
2039
2040         Spelling correction: seperate --> separate.
2041
2042         Removed `:'s that had creeped into some comments.
2043
2044         The repl now doesn't print #<unspecified> results any longer
2045         If the user wants to see this, he can do
2046         (assert-repl-print-unspecified #t) in his startup file.
2047
2048         The user now gets a friendly message instead of a backtrace at
2049         error.
2050
2051         Added `before-read-hook'.
2052
2053         Load module (ice-9 emacs) if option `-e' was specified.
2054
2055         (provide): New function.
2056
2057         (error): Save stack at entry, so that Guile entrails won't show up
2058         in backtraces.
2059
2060         (backtrace): New function.
2061
2062         (save-stack): Can now take arbitrary number of stack narrowing
2063         specifier pairs.  The first specifier in a pair controls inner
2064         border, the second the outer border.  A number means cut that
2065         number of frames, a procedure object means cut until that object
2066         is found in operator position in a frame.
2067
2068         * debug.scm: Enable debugging evaluator and recording of positions
2069         by default.
2070
2071         * slib.scm (slib:load): Adapt to the new behavior of
2072         primitive-load: It doesn't any longer try both with and without
2073         ".scm" extension.  (We don't want to use %search-load-path here.)
2074
2075         (implementation-vicinity): New function.  slib requires it
2076
2077         (library-vicinity): Updated.
2078
2079         Load "require.scm" in the library-vicinity.
2080
2081         (install-require-vicinity, install-require-module): New functions.
2082
2083 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
2084
2085         * boot-9.scm (load-from-path): New function.
2086
2087         * boot-9.scm (try-load, basic-try-load, try-load-module,
2088         try-load): Deleted.  I don't think they're being used.
2089
2090         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
2091         so they'll get distributed.
2092
2093         Get Guile to be a little less chatty by default.  The new user
2094         should see as little clutter as possible.
2095         * r4rs.scm (%load-verbosely): Make this #f by default.
2096         * boot-9.scm (scm-repl-verbose): Make this #f by default.
2097         (scm-style-repl): Don't run 'pk' on the value passed to quit.
2098
2099         * r4rs.scm: New file.
2100         * boot-9.scm: Load r4rs.scm, first thing.
2101         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
2102         open-output-file, open-io-file, close-input-port,
2103         close-output-port, close-io-port, call-with-input-file,
2104         call-with-output-file, with-input-from-port, with-output-to-port,
2105         with-error-to-port, with-input-from-file, with-output-to-file,
2106         with-error-to-file, with-input-from-string, with-output-to-string,
2107         with-error-to-string, the-eof-object): Definitions moved to
2108         r4rs.scm.  Not all of them are R4RS, but those that are use those
2109         that are not.
2110         (load, %load-verbosely, %load-announce): Moved, along with code to
2111         set %load-hook, to r4rs.scm.
2112
2113         * test.scm: New file.
2114
2115         * boot-9.scm (integer?): Definition deleted, in favor of the one
2116         present in libguile (which used to be called int?).  I have no
2117         idea why integer? didn't just call int? to begin with.
2118
2119         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
2120         =?, >?, and >=? deleted; they're defined that way by libguile now.
2121
2122         * boot-9.scm (load): Simplified; primitive-load does most of this
2123         work now.
2124         (%load-announce-win): Removed; no longer used.  Set %load-hook to
2125         call %load-announce.
2126
2127 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
2128
2129         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
2130         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
2131         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
2132         components.
2133         (file-is-directory?): use stat:type.
2134
2135 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
2136
2137         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
2138         that's now taken care of in libguile, and in a way compatible with
2139         SCSH (which this isn't).

2143         * boot-9.scm: Formatting tweaks.
2144
2145 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2146
2147         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
2148         after-error-hook, before-backtrace-hook and after-backtrace-hook
2149         to the error handler.  E.g.: fancy emacs support could plug into
2150         these.
2151         (save-stack): New function.  The stack is now made differently
2152         depending on the stack id.  (The motivation is to make a better
2153         choice regarding what stack frames to present to the user.)
2154         (error-catching-loop): Stack handling code moved outside into
2155         save-stack.
2156
2157 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
2158
2159         * Makefile.in (scm_files): add expect.scm.
2160
2161         * expect.scm: new file ported from guile-iii.
2162
2163         * boot-9.scm: remove handle-system-error, after moving the code into
2164         error-catching-loop.
2165         Don't set 'throw-handler-default property on error keys.
2166         Just interpret (almost) any throw with 4 args as an error throw.
2167         Delete some try-load stuff that was already commented out.
2168
2169         Second thoughts, keep handle-system-error but call it from
2170         error-catching-loop.
2171
2172 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
2173
2174         * boot-9.scm: Doc fixes.
2175         (make-module): Rework for readability.
2176         (make-root-module, make-scm-module): USES argument to make-module
2177         should be '(), not #f.
2178
2179         * boot-9.scm (try-load): %sys-load-path has been renamed to
2180         primitive-load-path; adjust call here.
2181
2182 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2183
2184         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
2185         the stack to the correct place: when it is decided to generate an
2186         error-signal.
2187
2188 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2189
2190         * boot-9.scm (error-catching-loop, signal-handler,
2191         handle-system-error): Backtracing now works for signals aswell;
2192         Backtracing mechanism can now identify the stack root created by
2193         start-stack so that the user isn't exposed to system stack frames.
2194
2195 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2196
2197         * Makefile.in: Added threads.scm.
2198
2199 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2200
2201         * debug.scm (make-enable, make-disable): Simplified.
2202
2203         * boot-9.scm: Renamed %%throw-handler-default -->
2204         throw-handler-default.
2205         ((handle-system-error key . arg-list)): Changed the way errors are
2206         reported.
2207         ((scm-style-repl)): Wrap up the call to eval in a start-stack
2208         acro.
2209         ((error-catching-loop thunk)): Introduce a lazy-catch into
2210         error-catching-loop so that the stack can be captured.
2211
2212 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2213
2214         * mapping.scm (hash-table-mapping): Explicitly request that
2215         make-vector fill new vectors with '(); this will make it easier to
2216         port Guile Scheme code to other Schemes.
2217         * boot-9.scm (make-print-style, make-print-table): Same.
2218
2219 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
2220
2221         * boot-9.scm (load): rewritten again.
2222         Append "." to the default %load-path.
2223         (feature?): new function: checks for a symbol in the features list.
2224         (module-local-variable): remove apparently useless (caddr (list m v
2225         ...))
2226         (%load-announce): minor formatting change.
2227         (file-exists?): use access? if posix is featured.
2228         (file-is-directory?): use stat if i/o-extensions is featured.
2229         (try-module-autoload module-name): use file-exists? before
2230         file-is-directory?
2231
2232 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
2233
2234         * boot-9.scm: Added conditional loading of threads.scm.
2235
2236         * threads.scm: New file.  Modified from the Cygnus-r0.3
2237         distribution.
2238
2239         * boot-9.scm (error-catching-loop): Added handling of key
2240         `switch-repl'.
2241
2242         * boot-9.scm: Name change %%bad-throw --> bad-throw.
2243
2244 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2245
2246         * boot-9.scm (make-record-type, record-constructor): Don't assume
2247         the empty list is false when parsing the argument list.
2248
2249 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2250
2251         * boot-9.scm (signal-handler): Clean up logic.
2252
2253         * boot-9.scm (load): Assume %load-path is always bound.
2254
2255 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2256
2257         * boot-9.scm (error): replace another throw with scm-error.  Throw
2258         to 'misc-error instead of 'error (no need to distinguish these.)
2259         Don't set up 'error as a key.
2260         Set up regex-error as a key, if regex is available.
2261         (signal-handler): use scm-error, not throw.
2262
2263         (%try-load, try-load-with-path, %load, load-with-path,
2264         basic-try-load-with-path, basic-load-with-path,
2265         try-load-module-with-path,load-module-with-path): deleted, since
2266         they seem redundant.
2267         (try-load): define using %try-load, not try-load-with-path.
2268         (load): rewritten.  load tries to open the file directly and
2269         with a .scm extension before searching the library directories
2270         (should "." be added to %load-path?  then load could still open
2271         directly files starting with "/").
2272         (try-module-autoload): use load, not load-with-path.
2273         (%load-indent): deleted, -2 was causing errors.
2274
2275         (%read-sharp): use port-line, not line-number.
2276
2277 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2278
2279         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
2280         straightforward to provide the equivalent functionality using
2281         (catch #t ...), so there's no need for the extra complexity.  2)
2282         Outside the context of a read-eval-print loop (which Guile should
2283         not require) it's not clear we should do anything more complicated
2284         than print an error and exit; the user or REPL can establish
2285         something better if it wants.  3) In that case, it's much more
2286         robust to just do it in the C code.
2287
2288 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
2289
2290         * boot-9.scm (%try-load): define using primitive-load.  Previously
2291         %try-load itself was the primitive.
2292         (load-with-path): use scm-error instead of %load-announce-lossage.
2293         Errors are thrown to 'misc-error instead of 'could-not-load.
2294         (%load-announce-lossage): deleted.
2295
2296 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
2297
2298         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
2299         (make-record-type type-name fields): Temporarily remove support
2300         for printing of records (not possible yet with C printer).
2301
2302 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
2303
2304         * boot-9.scm (file-exists?, file-is-directory): catch only
2305         system-error, not every kind of error.
2306         (scm-error): new procedure.
2307
2308 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2309
2310         * boot-9.scm: Formatting tweaks.
2311
2312 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2313
2314         * boot-9.scm (%%handle-system-error key): remove the code for
2315         SCM-style errors.  handle the case that an unexpected number
2316         of args are supplied.
2317         (%%system-errors): removed.
2318         (error): redefine using a throw with key and 4 args.
2319         ('error): associate 'error, 'error-signal keys with
2320         %%handle-system-error.
2321         (%%default-error-handler): removed.
2322         (signal-handler): throw with 4 args and use the error-signal key.
2323         Create an error message instead of using numerical codes.
2324         (%%bad-throw): call error instead of throw if key not found.
2325
2326 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
2327
2328         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
2329         (%%handle-system-error key): check subr is not #f before printing.
2330         Recognize %s (embed an argument using "display") and
2331         %S (embed an argument using "write").
2332
2333 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
2334
2335         * boot-9.scm (%%handle-system-error key): set args and rest to
2336         the empty list if they are #f.
2337         Initialize out-of-range as an error key.
2338
2339 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
2340
2341         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
2342
2343         * boot-9.scm: remove leading %% from references to '%%system-error.
2344         (%%handle-system-error): don't pass all the thrown arguments when
2345         aborting, just the key and subr.
2346         Remove the code to "Install default handlers for built-in errors."
2347         Remove the definition of the syserror procedure.
2348         Associate 'numerical-overflow with default handler.
2349
2350 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2351
2352         * boot-9.scm: Name change: value-ref --> local-ref
2353         resolved-ref --> nested-ref  Motivation: conformance to the other
2354         dictionary operators: list-ref operates on list, vector-ref
2355         operates on vector, nested-ref operates on nested namespace,
2356         local-ref operates on the local nested namespace.
2357
2358 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
2359
2360         * boot-9.scm (%%handle-system-error): recognise errors thrown
2361         by lgh-error (fill-message etc.)
2362         (fill-message): check first whether args is null.
2363         (fill-message): bug fix and check that args is a list.
2364
2365 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
2366
2367         * boot-9.scm: %load-path is initialized in C code now.
2368         (implementation-vicinity, parse-path): Deleted, along with code to
2369         initialize %load-path.
2370
2371         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
2372         "/", use one to separate it from the file.
2373
2374 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
2375
2376         * boot-9.scm (%load-path): Add the site directory.
2377         Add the directory named after the version number.
2378         Prepend the version number to the other directories in the path.
2379         Simplify by mapping the common prefix onto each item.
2380         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
2381         sitedatadir): New definitions.
2382         (libparent, libdir, install_path): Replaced by above.

2384         Put the source files into subpkgdatadir.
2385         (uninstall): Remove the above directories.
2386
2387 Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
2388
2389         Don't use the PLUGIN system to gather information for the
2390         Makefile's distribution and installation targets; just put it all
2391         in the Makefile directly.
2392         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
2393         for these.
2394         * configure.in: Remove code that gets and substitutes scm_files and
2395         aux_files.
2396         * Makefile.in (scm_files, aux_files): Write out the list of files
2397         here, where people expect to find them.

2400
2401         * boot-9.scm: Preliminary solution: optionally load the debug
2402         module.  Changed "gls" to "guile1.0b3".
2403
2404         * debug.scm: New file: debug extensions.
2405
2406 Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2407
2408         * boot-9.scm (print-vector): Renamed weak-hash-table? -->
2409         weak-key-hash-table?.  (Again!)
2410
2411 Tue Aug 20 07:31:39 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2412
2413         * boot-9.scm (print-vector, macro-table, xformer-table):
2414         Renamed weak-hash-table --> weak-key-hash-table.
2415
2416         * poe.scm (funcq-memo): Renamed weak-hash-table -->
2417         weak-key-hash-table.
2418
2419 Sat Aug  3 06:16:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
2420
2421         * boot-9.scm (*null-device*): global constant from goonix.
2422         (move->fdes): adjusted for boolean primitive-move->fdes.  return
2423         the modified port, always set revealed count to 1 (SCSH compatible).
2424         (release-port-handle port): from goonix (SCSH compatible).
2425         (%open-file): removed.
2426         (open-input-file, open-output-file, file-exists?, file-is-directory?):
2427         modified for open-file change (does not return #f).
2428
2429 Thu Aug  1 02:52:42 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2430
2431         * Makefile.in (dist-dir): New target for new dist system.
2432         (manifest): Deleted.
2433         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
2434         directory, and needs special treatment in the dist-dir target.
2435
2436 Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>
2437
2438         * boot-9.scm: remove the wrappers for '%' system primitives,
2439         now that they throw errors directly.
2440         remove make-simple-wrapper and similar functions.
2441         protect a call to getenv which may now throw an exception.
2442
2443 Wed Jul 31 23:44:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
2444
2445         * boot-9.scm (false-if-exception): new macro.
2446
2447 Fri Apr 19 13:53:08 1996  Tom Lord  <lord@beehive>
2448
2449         * The more things change...
2450
2451
