ice-9/ChangeLog

   1 2000-05-14  Gary Houston  <ghouston@arglist.com>
   2
   3         * boot-9.scm (load-user-init): rewritten.  first work out the home
   4         directory and then try to open the file (previously it could try
   5         to open a file in more than one place).  catch exceptions when
   6         trying to get a directory from the user database.  don't check
   7         that ~/.guile is not a directory before trying to load it (a lack
   8         of ~/.guile is not a crime, but if the file is not valid for any
   9         reason then primitive-load will raise an error).
  10
  11 2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  12
  13         * boot-9.scm (abs):  Don't set to magnitude.  abs now does not
  14         accept complex numbers as parameter.
  15
  16 2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
  17
  18         * common-list.scm (delete-if-not!): Bug fix of bug fix: change
  19         label of named let to `delete-if-not'.  Sorry.
  20
  21 2000-05-08  Marius Vollmer  <mvo@zagadka.ping.de>
  22
  23         * common-list.scm (doc fixes): Talk about `true values' instead of
  24         `#t' when a function treats all non-#f valuers the same.
  25         (remove-if-not): Bug fix: call remove-if-not
  26         instead of remove-if when iterating.
  27         (delete-if-not!): Bug fix: call delete-if-not! instead of
  28         delete-if! when iterating.
  29
  30 2000-04-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  31
  32         * r4rs.scm (close-input-port, close-output-port): Removed.
  33
  34 2000-04-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  35
  36         * session.scm (help): New macro.  Prints helpful information.
  37
  38 2000-04-10  Gary Houston  <ghouston@arglist.com>
  39
  40         * popen.scm (open-process): after forking, close all ports except
  41         the end of the pipe to the parent.  otherwise move->fdes and
  42         the exec'd program and the exit handlers can interfere with file
  43         descriptors still in use in parent ports.
  44
  45 2000-04-09  Gary Houston  <ghouston@arglist.com>
  46
  47         * popen.scm (close-process-quietly): new procedure.  use it from
  48         reap-pipes to avoid errors or hanging during background cleanup.
  49
  50 2000-04-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  51
  52         * format.scm (format:obj->str): Handle circular references.  Also,
  53         print improper lists with (x y . z) syntax rather than as
  54         individual pairs.  (This code should probably be integrated into C
  55         level facilities.  It is currently terribly slow.)
  56
  57 2000-04-03  Michael Livshin  <mlivshin@bigfoot.com>
  58
  59         * streams.scm (stream-fold, stream-for-each): don't use named let,
  60         because it prevents the gc from junking the stream argument.
  61
  62 Thu Mar  9 08:05:08 2000  Greg J. Badros  <gjb@cs.washington.edu>
  63
  64         * slib.scm: Back-out change to software-type -- renamed
  65         slib:software-type to software-type, and leave it non-public.
  66
  67 Thu Mar  2 12:20:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
  68
  69         * boot-9.scm: Drop unused definition of sfx function -- thanks
  70         Dirk Hermann!
  71
  72 Wed Mar  1 12:21:02 2000  Greg J. Badros  <gjb@cs.washington.edu>
  73
  74         * streams.scm: Doc patch from Richard Kim, using MIT Scheme as
  75         source of the numerous very short changes.
  76
  77 Sun Feb 13 18:03:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
  78
  79         * slib.scm: Rename software-type to slib:software-type and make it
  80         public.
  81
  82         * r4rs.scm: Added documentation; largely cut and pasted from R4RS
  83         info pages.
  84
  85 Sun Feb 13 17:49:29 2000  Greg J. Badros  <gjb@cs.washington.edu>
  86
  87         * common-list.scm: Added documentation; largely cut and pasted
  88         from slib docs.
  89
  90 2000-02-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  91
  92         * format.scm (format): Reintroduce (define format format:format)
  93         so that the binding in the public interface of the module will be OK.
  94
  95 2000-01-30  Gary Houston  <ghouston@arglist.com>
  96
  97         * boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
  98         to string-append.
  99
 100 2000-01-29  Gary Houston  <ghouston@arglist.com>
 101
 102         * expect.scm (expect): don't call char-ready? before expect-select,
 103         since select now checks port buffers itself.  don't bother to check
 104         the time first either, since expect-select does it.
 105
 106 Thu Jan 20 12:57:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
 107
 108         * format.scm: Use (variable-set! (builtin-variable 'format)) to
 109         re-define format to be format:format (instead of just define,
 110         which interacts poorly with the module system).  Thanks to Shuji
 111         Narazaki for this change.
 112
 113 Tue Jan 11 10:49:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
 114
 115         * boot-9.scm expect.scm, syncase.scm: Switch to new style
 116         `simple-format' message strings: substitute ~A for %s, and ~S for
 117         %S.
 118
 119         * boot-9.scm:  Added (define format simple-format) to expose that
 120         primitive via the simpler name until format.scm is loaded.
 121
 122 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
 123
 124         * boot-9.scm (try-using-libtool-name): Do not bother to look
 125         inside libtool ".la" file, dynamic-link does this for us now.
 126
 127 1999-12-15  Gary Houston  <ghouston@freewire.co.uk>
 128
 129         * slib.scm (library-vicinity, home-vicinity,
 130         scheme-implementation-type, scheme-implemenation-version):
 131         use define-public to export from the module.
 132
 133 Wed Dec 15 08:32:09 1999  Greg J. Badros  <gjb@cs.washington.edu>
 134
 135         * doc.scm: Use `%library-dir' and the other system directories,
 136         not the quickly defuncted `library-dir' that I added before
 137         realizing the former existed.  Thanks Brad Knotwell!
 138
 139 Sun Dec 12 19:18:52 1999  Greg J. Badros  <gjb@cs.washington.edu>
 140
 141         * Makefile.am, doc.scm: Added doc.scm.
 142
 143 1999-12-12 18:54:06 1999  Greg J. Badros  <gjb@cs.washington.edu>
 144
 145         * popen.scm, slib.scm: Added some docstrings for procedures that
 146         were primitives that I encountered in posix.texi.
 147
 148 1999-11-19  Gary Houston  <ghouston@freewire.co.uk>
 149
 150         * Makefile.am (ice9_sources): add arrays.scm.
 151
 152         * boot-9.scm: load arrays.scm if 'array is provided.
 153
 154         * arrays.scm: new file with stuff from boot-9.scm.
 155
 156 1999-11-18  Gary Houston  <ghouston@freewire.co.uk>
 157
 158         * boot-9.scm (read-hash-extend to set up arrays): add 'l' for
 159         long_long uniform vectors.
 160
 161 1999-11-17  Gary Houston  <ghouston@freewire.co.uk>
 162
 163         * networking.scm (sethostent, setnetent, setprotoent, setservent):
 164         take an optional argument STAYOPEN.  default is #f.
 165
 166 1999-10-05  Jim Blandy  <jimb@savonarola.red-bean.com>
 167
 168         * Makefile.in: Deleted from CVS repository.  Run the autogen.sh
 169         script to create generated files like this one.
 170
 171 1999-09-23  Gary Houston  <ghouston@freewire.co.uk>
 172
 173         * boot-9.scm (load-user-init): check that the posix feature is
 174         available before using getpw and getuid.
 175         (top-repl): don't install handlers for SIGINT etc., without posix.
 176         (file-is-directory?): use 'posix instead of i/o-extensions to
 177         check for stat.
 178         (load-user-init): use file-exists? and file-is-directory? to
 179         check for .guile, instead of stat.
 180         (file-is-directory?): don't display the file name if posix not
 181         available.
 182         (feature?): I guess this is deprecated.  redefined using "provided?"
 183         and changed users in boot-9.scm to "provided?".
 184         Conditionally load posix.scm and networking.scm.
 185
 186         posix.scm, networking.scm: new files.  Move definitions from
 187         boot-9.scm if they are only useful with posix/networking available.
 188
 189         * Makefile.am (ice9_sources): add posix.scm, networking.scm.
 190
 191 1999-09-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 192
 193         * debugger.scm (read-and-dispatch-commands): Handle other throws
 194         than 'exit-debugger.
 195
 196         * boot-9.scm (before-signal-stack): New fluid.
 197         (top-repl): Set before-signal-stack in the signal handler.
 198
 199         * debugger.scm (eval-handler): Handle unhandled exceptions.
 200
 201 1999-09-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 202
 203         * debugger.scm ("p"): New alias for "evaluate";

 207         (display-source): Display position of expression, if available.
 208         (catch-user-errors): Return #f on error.  (Commands are expected
 209         to return a valid state.)
 210         (read-and-dispatch-command): Bugfix: Return old state on error.
 211
 212 1999-09-16  Jim Blandy  <jimb@savonarola.red-bean.com>
 213
 214         * regex.scm (regexp-substitute/global): Handle the end of the
 215         match list and an empty match list identically.  (Thanks to Greg
 216         Badros.)
 217
 218 1999-09-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 219
 220         * debugger.scm ("evaluate"): Replaced `write-line' with calls to
 221         `write' and `newline' since write-line doesn't write but displays.
 222
 223 1999-09-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 224
 225         * debugger.scm ("evaluate"): Newline after no env announcement.

 234         (write-frame-long/application): Also print corresponding source
 235         expression.
 236         ("evaluate"): Evaluate in local environment frame, if existent;
 237         Handle errors.
 238
 239 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 240
 241         * format.scm (format:format-work): Use #\tab and #\page instead of
 242         slib:form-feed and slib:tab.  (Thanks to Ceri Storey.)
 243
 244         * format.scm (format:abort): Call error, not slib:error.
 245
 246 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 247
 248         * boot-9.scm (using-readline?): New procedure: Returns #t if
 249         readline is used by the repl run by this thread.
 250         (handle-system-error): Print "Backtrace:" before backtrace since
 251         this is no longer done by display-backtrace.
 252
 253         * debug.scm (frame-number->index): Optionally take stack as
 254         argument.
 255
 256         * debugger.scm: Use the frame number abstraction which allows for
 257         both forward and backward views of the stack
 258         (write-frame-index-short, write-frame-index-long):
 259         Use selector `frame-number';
 260         (select-frame-absolute): Use frame-number->index.
 261         ("backtrace"): Use builtin backtrace printing.
 262         Use (ice-9 debug).
 263         Use readline conditionally.
 264
 265 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 266
 267         * regex.scm (fold-matches, list-matches): New functions.
 268         (regexp-substitute/global): Rewritten again in terms of
 269         list-matches, to get null match behavior correct.
 270
 271         * regex.scm (regexp-substitute/global): Rewrite so that 'post at
 272         the end of the item list actually causes a tail call.  (Thanks to
 273         Jan Nieuwenhuizen.)
 274
 275 1999-09-11  Marius Vollmer  <mvo@zagadka.ping.de>
 276
 277         * readline.scm: Moved to ../guile-readline.
 278
 279         * boot-9.scm (top-repl): Removed code for activating readline.
 280
 281         * Makefile.am: Removed mention of readline.scm.
 282
 283         * Makefile.in: Regenerated.
 284
 285 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 286
 287         Delete the test which compares the configuration date of libguile
 288         with the configuration date of ice-9.  This test yields too many
 289         false positives to be helpful.  For example, if you build Guile
 290         for several architectures but have them all share a "share"
 291         directory (which is supposed to work), then all but one
 292         architecture's Guile will complain that the configuration dates
 293         don't match.  Which is true, but indicates nothing wrong.
 294         * boot-9.scm: Delete code which compares ice-9-config-stamp with
 295         libguile-config-stamp.
 296         * version.scm.in: Delete.
 297         * Makefile.am (ice9_generated): Delete.
 298         (subpkgdata_DATA): Remove ice9_generated.
 299         (EXTRA_DIST): Remove version.scm.in.
 300         * Makefile.in: Regenerate.
 301
 302 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 303
 304         * debugger.scm: New file: Initial version of the Guile debugger
 305         written by Chris Hanson.  (The debugger isn't finished, but is
 306         included in Guile anyway since it is already quite useful.)
 307
 308         * boot-9.scm (top-repl): Use (ice-9 debug) (ice-9 debugger) (ice-9
 309         session) (ice-9 threads) (ice-9 regex) from guile-user only if
 310         top-repl is called.  This makes startup time for scripts 30% of
 311         what it was before...  Removed redundant code for loading of
 312         readline.
 313
 314         * Makefile.am (ice9_sources): Added debugger.scm.
 315
 316 1999-08-29  Keisuke Nishida  <kxn30@po.cwru.edu>
 317
 318         * boot-9.scm (try-module-autoload): Use %search-load-path.
 319
 320 1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 321
 322         * boot-9.scm: Removed old style hooks.
 323         (inherit-print-state): Rwwritten to use port-with-print-state.
 324
 325 1999-08-20  James Blandy  <jimb@mule.m17n.org>
 326
 327         Remove support for the #/ path list syntax entirely.
 328         * boot-9.scm (read-path-list-notation,
 329         read-path-list-notation-warning): Deleted.
 330         Don't register read-path-list-notation-warning as a reader for
 331         objects starting with '#/'.
 332
 333 1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 334
 335         GOOPS needs the observer protocol specified for the new module
 336         system.  Here's a simple version for the old module system:
 337         * boot-9.scm (module-observers, module-weak-observers,
 338         module-observer-id, set-module-observers!,
 339         set-module-observer-id!): New accessors.
 340         (module-type): Added slots `observers', `weak-observers' and
 341         `observer-id'.
 342         (module-observe, module-observe-weak, module-unobserve,
 343         module-modified): New procedures.
 344         (module-make-local-var!, module-add!, module-remove!,
 345         module-clear!, module-define!, module-use!): Call module-modified.
 346
 347 1999-07-29  Marius Vollmer  <mvo@zagadka.ping.de>
 348
 349         * boot-9.scm (error-catching-loop): Correct non-RnRS usage of internal
 350         defines.
 351
 352 1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>
 353
 354         * streams.scm: New module, contributed by Michael Livshin.
 355         * Makefile.am (ice9_sources): List it.
 356         * Makefile.in: Regenerated.
 357
 358         * boot-9.scm (read-delimited!): Put the terminator in the correct
 359         position.
 360
 361 1999-06-29  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 362
 363         * readline.scm: Bugfix: Avoid getting the continued-lines prompt
 364         at multiple calls to read.
 365         (promtp2): Variable for continued-lines prompt.
 366         (make-readline-port): Use prompt2.
 367         (set-readline-prompt!): New optional arg which sets
 368         continued-lines prompt.
 369
 370         * boot-9.scm (top-repl): Set/clear readline prompts before/after
 371         reading expressions.
 372
 373 1999-06-18  Jim Blandy  <jimb@savonarola.red-bean.com>
 374
 375         * ls.scm (ls, lls): Handle no arguments as meaning to look in
 376         `(current-module)'. (Patch from Thien-Thi Nguyen.)
 377
 378 1999-06-14  Jim Blandy  <jimb@savonarola.red-bean.com>
 379
 380         * string-fun.scm (split-before-predicate, split-after-predicate,
 381         split-discarding-predicate): Make these public.  (Thanks to
 382         Thien-Thi Nguyen.)
 383
 384         1999-06-13  Gary Houston  <ghouston@easynet.co.uk>
 385
 386         * more changes to expect.scm, to avoid the one-character lookhead
 387         that was introduced to fix the $ problem:
 388
 389         * expect.scm (expect): call the match proc an extra time at end
 390         of file and set the eof? argument appropriately.  call
 391         expect-eof-proc only if the last call didn't match.
 392         * expect.scm (expect-strings): change port to eof? in match proc.
 393         * expect.scm (expect-regexec): take an eof indicator as an argument
 394         instead of a port.
 395
 396 1999-06-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 397
 398         * Makefile.am (ice9_sources): Add popen.scm to list.
 399         * Makefile.in: Regenerated.
 400
 401         Fixes for expect from Gary Houston  <ghouston@easynet.co.uk>:
 402
 403         * expect.scm (expect-regexec): define 'eof-next?'.  I don't
 404         know why it was missing.  also don't peek for end of lines
 405         unless expect-strings-exec-flags contains regexp/noteol.
 406         (expect-strings-exec-flags): initialise to regexp/noteol.
 407
 408         Gary Houston's open-buffer port patches:
 409
 410         1999-04-01  Gary Houston  <ghouston@easynet.co.uk>
 411
 412         * popen.scm: applied fixes from Greg Harvey.  use a guardian
 413         and a gc-thunk so that cleanup is done if a pipe is garbage
 414         collected or closed with close-port.  use a weak hash-table instead of
 415         an alist.
 416
 417         1999-03-20  Gary Houston  <ghouston@easynet.co.uk>
 418
 419         * expect.scm (expect): call the match proc with the port instead.
 420         (expect-strings): use peek-char to get the next char.  this has
 421         the advantage of getting the handling of $ "correct", but the
 422         disadvantage of needing to get (and maybe block for) an extra character
 423         from the port when it may not be needed.  hence:
 424         (expect-strings-exec-flags): new variable/parameter, supplies
 425         flags for regexp-exec.  if this includes regexp/noteol, then
 426         automatic regexp/noteol handling (requiring an extra peeked char)
 427         is enabled.  default is regexp/noteol.
 428         (expect-strings-compile-flags): new variable/parameter, supplies
 429         flags for make-regexp.  default is regexp/newline.
 430
 431         1999-03-15  Gary Houston  <ghouston@easynet.co.uk>
 432
 433         * expect.scm (expect): call the match proc with an extra char,
 434         peeked from the stream.
 435         (expect-strings): build a match proc which takes the extra char.
 436         (expect-regexec): take an extra arg "eof-next?" and use it
 437         to decide whether the regexp/noteol flag should be added.
 438
 439         1999-02-26  Gary Houston  <ghouston@easynet.co.uk>
 440
 441         * boot-9.scm (top-repl): don't flush all ports at exit.
 442         (error-catching-loop): likewise.
 443
 444         1998-12-23  Gary Houston  <ghouston@easynet.co.uk>
 445
 446         * boot-9.scm (scm-style-repl): -read: don't call
 447         consume-trailing-whitespace if val is eof object.  Allows
 448         exiting repl with single control-D.
 449
 450         1998-12-06  Gary Houston  <ghouston@easynet.co.uk>
 451
 452         * boot-9.scm (error-catching-loop): don't force output within
 453         error catching loop after quit received.
 454         (top-repl): flush all ports when the repl terminates.
 455
 456         * boot-9.scm (error-catching-loop): flush all ports before
 457         primitive exit if non-interactive.
 458         force-output on current-error-port if interactive.
 459
 460         * boot-9.scm (reopen-file): deleted.
 461         * popen.scm (open-output-pipe, open-input-pipe): moved from
 462         boot-9.scm.
 463         * popen.scm: new file.
 464
 465 1999-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 466
 467        * boot-9.scm (iota):  replaced by a tail recursive version.
 468        (reverse-iota):  removed.
 469
 470 1999-06-03  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 471
 472         * optargs.scm (lambda*): Bugfix: Replaced ARGLIST -->
 473         non-optional-args.  (Thanks to David Lutterkort.)
 474
 475 1999-05-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 476
 477         * string-case.scm: Removed; functions moved to libguile/strop.c
 478         (which could be dynamically linked in the future anyway).
 479         * Makefile.am (ice9_sources): Don't list string-case.scm.
 480         * Makefile.in: Regenerated.
 481         * format.scm: Don't bother importing (ice-9 string-case).
 482
 483 1999-05-02  Jim Blandy  <jimb@savonarola.red-bean.com>
 484
 485         * boot-9.scm (provided?): New function.
 486
 487         * Makefile.am: Add string-case.scm and format.scm to ice9_sources.
 488         * Makefile.in: Regenerated.
 489
 490         * string-case.scm: New file, brought in from SLIB, and adapted to
 491         Guile's module system.
 492
 493         * format.scm: New file, brought in from SLIB, with the following
 494         changes:
 495         (format:format): If the first argument is the format string, stick
 496         a #f on the front of it, so it is now a valid CL format argument
 497         list.  This is easier than changing everyplace else (like the
 498         error formatter) that expects it to be in CL form.  The other
 499         clause which explicitly tests for this case is now dead code.
 500         (format:format-work): Allow `@' and `:' in either order, as per
 501         modern CL behavior.
 502         (format:num->cardinal): Don't assume that an elseless if returns
 503         '() when the condition is false.
 504
 505 1999-04-17  Jim Blandy  <jimb@savonarola.red-bean.com>
 506
 507         * Makefile.in: Regenerated.
 508
 509 1999-04-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 510
 511         * boot-9.scm: Provide 'values.
 512
 513 1999-03-21  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 514
 515         * boot-9.scm (process-define-module, use-syntax): Bugfix:
 516         :use-syntax should add syntax to using module, not current module.
 517         (internal-use-syntax): Removed.
 518
 519 1999-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 520
 521         * session.scm (apropos-internal): Modified to comply with new
 522         argument order for hash-fold.
 523
 524 1999-03-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 525
 526         * boot-9.scm (try-load-module): New procedure.  Broken out from
 527         resolve-module.
 528         (resolve-module): Bugfix: Make it possible for a module at a
 529         deeper level (x y z) to depend on a module on a higher (x y).
 530
 531         This also has the desired side-effect that multiple attempts to
 532         load a module (e.g. with `use-modules') work until source is
 533         actually found for the module (e.g. because the correct catalog
 534         has been added to the load path).
 535
 536         Use try-load-module.
 537
 538 1999-03-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 539
 540         * session.scm (system-module): New procedure.  Used to switch a
 541         module between system and user state.
 542
 543 1999-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 544
 545         * session.scm (apropos-internal): Rewritten using hash-fold.
 546
 547         * emacs.scm, session.scm, slib.scm): Added :no-backtrace in module
 548         definition.
 549
 550 1999-03-14  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 551
 552         * boot-9.scm (make-record-type): Use `set-struct-vtable-name!' to
 553         associate a name to the record type descriptor so that the object
 554         system can create a wrapper class for it.
 555
 556 1999-03-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 557
 558         Improvement of backtraces: Introduces a new stack narrowing
 559         specifier, #t, for the inner cut.  If the inner cut is specified
 560         by #t, `make-stack' will throw away inner stack frames (most
 561         recent calls on call chain) up to but excluding the first user
 562         stack frame encountered.
 563
 564         This specifier is now used in `save-stack' so that the call
 565         `(save-stack)' will get the new behaviour. [It is recommended that
 566         any error reporting functions written by the user have this call
 567         on the outermost expression level (i.e. as a member of the lambda
 568         list).]
 569
 570         Modules are partitioned into "user" and "system" modules. [I know
 571         that some names used here are silly, but I don't have more time to
 572         spend on a better solution, especially considering that the module
 573         system will be replaced.  But if people have better ideas, then
 574         please tell me!]
 575
 576         System modules are created by adding :no-backtrace among the
 577         define-module switches:
 578
 579         (define-module (foo)
 580           :no-backtrace)
 581
 582         Modules which doesn't have the :no-backtrace specifier are user
 583         modules.
 584
 585         A stack frame is classified as a user frame if it has source code
 586         associated with it and if this source code can be proven to come
 587         from a user module.  If it can be proven to come from a system
 588         module it is a system frame.
 589
 590         Frames which can't be classified, e.g. application frames, are cut
 591         away if they occur between system frames, but are left on the
 592         stack if they occur between the last system frame and the first
 593         user frame encountered.  (Note that the first user frame
 594         encountered is the last user code being evaluated!)
 595
 596         In some cases the system part of the call chain is introduced by
 597         frames which should but can't be proven to be system frames.  The
 598         following workaround has been implemented: The cutting proceeds
 599         over application frames where the operator is marked by the
 600         `system-procedure' property.  (This has been used to cut away
 601         generic function dispatch code in the object system.)
 602
 603         * boot-9.scm (set-system-module!): New procedure: Set system/user
 604         status of a module.;
 605         Mark `the-root-module' and `the-scm-module' as system modules.
 606         (process-define-module): Add new keyword :no-backtrace.
 607
 608         * boot-9.scm (environment-module): Bugfixed.
 609         (set-module-eval-closure!): Add a pointer back from the eval
 610         closure to the module.
 611
 612         * emacs.scm (emacs-load): Reset port filename after transfer.
 613
 614 1999-03-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 615
 616         * slib.scm (make-random-state): Added for compatibility.
 617
 618 1999-02-16  Maciej Stachowiak  <mstachow@alum.mit.edu>
 619
 620         * optargs.scm (lambda*): Handle empty argument lists properly.
 621
 622 1999-02-15  Jim Blandy  <jimb@savonarola.red-bean.com>
 623
 624         Fix from Russ McManus:
 625         * getopt-long.scm (parse-option-spec): Store 'optional as the
 626         value-required? field for options that take optional values.
 627         (process-short-option): Grab a value for the option when it takes
 628         either an optional or required value.
 629
 630 1999-02-12  Jim Blandy  <jimb@savonarola.red-bean.com>
 631
 632         * getopt-long.scm: Remove debugging calls to `pk'.
 633
 634         * getopt-long.scm: Return list of ordinary arguments as the value
 635         of the '() key, not `rest'.
 636
 637         A new argument-processing package from Russ McManus.
 638         * getopt-long.scm: New file.
 639         * Makefile.am (ice9_sources): Added getopt-long.scm.
 640         * Makefile.in: Regenerated.
 641
 642 1999-02-09  Maciej Stachowiak  <mstachow@alum.mit.edu>
 643
 644         * optargs.scm: New file.
 645         * Makefile.am (ice9_sources): Add optargs.scm here. Makefile.in
 646         not regenerated because I don't have the right version of Automake.
 647
 648 1999-02-06  Jim Blandy  <jimb@zwingli.cygnus.com>
 649
 650         * and-let*.scm: New file, from Michael Livshin.
 651         * Makefile.am (ice9_sources): Add and-let* here.
 652         * Makefile.in: Regenerated.
 653
 654 1999-01-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 655
 656         * slib.scm (install-require-module): Fixed the kludge which loads
 657         the slib catalog: Doesn't anylonger assume that the feature tested
 658         for isn't loaded.
 659
 660 1998-12-14  Jim Blandy  <jimb@zwingli.cygnus.com>
 661
 662         * Makefile.in: Regenerated.
 663
 664 1998-12-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 665
 666         * boot-9.scm (process-define-module): Reverted the change of
 667         1998-11-23 which caused loading of object code if :use-module was
 668         applied to the module itself.
 669
 670 1998-12-11  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 671
 672         * Makefile.am: Removed setf.scm.
 673
 674         * setf.scm: Removed.  1. It was buggy.  2. It was unschemey.
 675         (These shortcomings were my fault.)
 676
 677 1998-12-10  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 678
 679         * boot-9.scm (environment-module): New procedure.
 680
 681 1998-12-07  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 682
 683         * Makefile.am: Added setf.scm.
 684
 685 1998-12-05  Christian Lynbech  <chl@tbit.dk>
 686
 687         * setf.scm: New file.  Adds the new forms `setf!' and `setter'
 688         which implements generalized references a la Common LISP.
 689
 690 1998-12-02  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 691
 692         * boot-9.scm (process-define-module): Added new specifier
 693         :autoload MODULENAME BINDINGS to the define-module form.
 694         The autoload specifier tells the module system to load the module
 695         MODULENAME at the first occasion that any variable with its name
 696         among BINDINGS is referenced.
 697         (make-autoload-interface): New procedure:  Constructs a stand-in
 698         for the public interface for the module to be autoloaded.
 699
 700 1998-12-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 701
 702         * boot-9.scm (*suppress-old-style-hook-warning*): Set this to #t
 703         if you don't want the old style hook warnings.
 704
 705 1998-12-01  Christian Lynbech  <chl@tbit.dk>
 706
 707         * boot-9.scm (try-using-libtool-name): Fix check on dlname to make
 708         sure that it isn't empty, as it is when we are only buidling
 709         static libraries.
 710
 711 1998-11-27  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 712
 713         * session.scm (arity): New procedure.
 714
 715 1998-11-26  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 716
 717         * boot-9.scm: Use run-hook instead of run-hooks everywhere.
 718
 719 1998-11-26  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 720
 721         * boot-9.scm (run-hooks, add-hook!, remove-hook!): Added temporary
 722         code for backward compatibility until people have had time to
 723         adapt to the new hooks.
 724
 725 1998-11-23  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 726
 727         * boot-9.scm (beautify-user-module!): Beautify also if public
 728         interface is set to the module itself.  In this way we can use
 729         beautify-user-module! to beautify a module prepared for object
 730         code.
 731         (process-define-module): Special case: Try to load object code as
 732         well if a module does :use-module on itself.
 733
 734         * boot-9.scm: Bugfix: Since boot-9.scm is now loaded from
 735         invoke_main_func, we can no longer be sure that all modules have
 736         been registered when boot-9.scm is loaded.
 737         (register-modules): New function: Register and tag modules
 738         registered by scm_register_module_xxx since last call to this
 739         function.  Modules are tagged with the dynamic object passed as
 740         argument.  (Already linked modules should be tagged with #f.)
 741         (init-dynamic-module, link-dynamic-module): Call register-modules
 742         first to register linked modules.
 743
 744         * boot-9.scm (init-dynamic-module): Remove module from
 745         registered-modules as soon as possible in case we are recursively
 746         invoked; Set public interface before doing the dynamic-call.
 747
 748         * boot-9.scm (map-in-order): Removed (replaced by scm_serial_map).
 749         (abort-hook, before-error-hook, after-error-hook,
 750         before-backtrace-hook, after-backtrace-hook, before-read-hook,
 751         after-read-hook, exit-hook): Make hooks with `make-hook'.
 752
 753         * boot-9.scm: Make hooks first class citizens and make them easier
 754         to use from C:
 755         (make-hook, add-hook!, remove-hook!, run-hooks): Moved to
 756         libguile/feature.c.
 757
 758         * boot-9.scm: Added warnings about bindings used in
 759         libguile/modules.c: the-module, set-current-module,
 760         make-modules-in, beautify-user-module!, module-eval-closure.
 761
 762 1998-11-21  Mikael Djurfeldt  <mdj@kenneth>
 763
 764         * boot-9.scm (the-environment): New special form: Returns an
 765         object representing the current local evaluation environment.
 766         This object can be used in `local-eval' and `defined?'.
 767
 768 1998-11-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 769
 770         * boot-9.scm (collect): New syntax.  Similar to begin but returns
 771         a list of the results of all forms in the sequence instead of the
 772         result of the last form.
 773
 774 1998-11-10  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 775
 776         * boot-9.scm (values, call-with-values): Moved here from
 777         syncase.scm.
 778
 779         * syncase.scm (values, call-with-values): Moved to boot-9.scm.
 780
 781         * boot-9.scm (readline-options, readline-enable, readline.disable,
 782         readline-set!: New options interface.
 783
 784         * readline.scm (readline-port): Use readline-options-interface.
 785
 786 1998-11-05  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 787
 788         * boot-9.scm: Set the repl start module in `top-repl' instead of
 789         at the end of boot-9.scm.
 790
 791 1998-11-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 792
 793         * emacs.scm (format): Bugfix: Handle multiple arguments
 794         correctly.  (Thanks to Thien-Thi Nguyen.)
 795
 796 1998-11-01  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 797
 798         * boot-9.scm (exit-hook): New hook: Is run at the very end of an
 799         interactive session.
 800         (top-repl): Run exit-hook on exit.
 801
 802         * readline.scm (readline-port): Maybe read history; Maybe write
 803         history at exit (add to exit-hook).
 804
 805 Fri Oct 30 15:15:37 1998  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 806
 807         * readline.scm (make-readline-port): Bugfixed last change...
 808
 809 1998-10-28  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 810
 811         * readline.scm (make-readline-port): Don't set prompt to "... " if
 812         read line was empty.
 813
 814 1998-10-19  Jim Blandy  <jimb@zwingli.cygnus.com>
 815
 816         * boot-9.scm, debug.scm, expect.scm, hcons.scm, lineio.scm,
 817         r4rs.scm, slib.scm, threads.scm: Update copyright years.
 818
 819         * getopt-gnu-style.scm, slib.scm: Add copyright notice.
 820
 821         Talked to Stallman.  Actually, the syntax-case copyright is no
 822         problem.  Duh.
 823         * Makefile.am (ice9_sources): Revert last change.
 824         * syncase.scm, psyntax.pp, psyntax.ss: Added again.
 825         * Makefile.in: Regeneretade.
 826
 827         * boot-9.scm: Don't assume that this file is loaded just before
 828         entering a read-eval-print loop.  Turn code to load (ice-9 emacs)
 829         into...
 830         (load-emacs-interface): New function.
 831         (top-repl): Call it, if use-emacs-interface is defined and true.
 832         At this point, we *do* know we're about to enter a REPL.
 833
 834         We can't include Kent Dybvig's syntax-case macro expander in the
 835         core Guile distribution, because we don't have copyright
 836         assignments for this code.  We can certainly distribute them as a
 837         separate package, but Guile should be FSF code.
 838         * syncase.scm, psyntax.pp, psyntax.ss: Removed.
 839         * Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
 840         psyntax.ss.
 841         * Makefile.in: Regenerated.
 842
 843         * Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
 844         * Makefile.in: Regenerated.
 845
 846 1998-10-18  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 847
 848         * boot-9.scm: Added extended read syntax for byte vectors #y(...)
 849         and short vectors #h(...).
 850
 851 1998-10-14  Jim Blandy  <jimb@zwingli.cygnus.com>
 852
 853         * calling.scm (excursion-function-syntax): Use a sequence of
 854         set!'s, not a single multi-variable set!; we removed support for
 855         that syntax a long time ago.  (Thanks to Shuji Narazaki.)
 856
 857 1998-10-12  Jim Blandy  <jimb@zwingli.cygnus.com>
 858
 859         * r4rs.scm (OPEN_READ, OPEN_WRITE, OPEN_BOTH): Don't bother
 860         testing software-type here.  That's the least of our Windows
 861         porting issues, and it's done wrong anyway.
 862
 863 1998-10-09  Jim Blandy  <jimb@zwingli.cygnus.com>
 864
 865         * boot-9.scm (read-path-list-notation-warning): New function:
 866         print a warning the first time we see `#/' notation.
 867
 868         * q.scm (sync-q!, q?, q-remove!, q-push!, enq!): Lots of bugs, and
 869         (eq?  #f '()) assumptions.  Make functions that aren't documented
 870         to return anything else return the queue itself.  (Bug report from
 871         Michael Livshin --- thanks!)
 872
 873 1998-08-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 874
 875         * debug.scm (trace-entry, trace-exit): Removed re-enabling of
 876         trace flag.
 877
 878         * boot-9.scm (make-options): Bugfix: Changed pair? --> list? in
 879         order to allow the empty list as arg.
 880         (error-catching-loop): Use `with-traps' to create a dynamic
 881         context with traps enabled.
 882
 883 1998-08-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 884
 885         * boot-9.scm: Removed (ice-9 regex) from use-list of (guile)
 886         module.
 887         (try-using-libtool-name): Removed dependency on (ice-9 regex).
 888
 889 1998-08-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 890
 891         * boot-9.scm: Make the root module use (ice-9 regex) if
 892         available.  The dynamic linking facilities in boot-9.scm are
 893         currently dependent upon regular expressions.  My change of
 894         1998-07-14 removed (ice-9 regex) from the use-list of the root
 895         module and thereby destroyed dynamic linking.
 896
 897 1998-07-29  Jim Blandy  <jimb@zwingli.cygnus.com>
 898
 899         * Makefile.in: Regenerated using the last public version of
 900         automake, not the hacked Cygnus version.
 901
 902 1998-07-28  Jim Blandy  <jimb@zwingli.cygnus.com>
 903
 904         * Makefile.in: Regenerated, after removing Totoro kludge.
 905
 906 1998-07-28  Jim Blandy  <jimb@totoro.red-bean.com>
 907
 908         * getopt-gnu-style.scm: New file.  (Thanks to Russ McManus.)
 909
 910 1998-07-26  Jim Blandy  <jimb@zwingli.cygnus.com>
 911
 912         * Makefile.in Rebuilt, for config changes in parent dir.
 913
 914 1998-07-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 915
 916         * readline.scm (make-readline-port): Set prompt string to "... "
 917         after first read line.  (Thanks to Richard Polton.)
 918
 919 1998-07-19  Jim Blandy  <jimb@zwingli.cygnus.com>
 920
 921         * lineio.scm (make-line-buffering-input-port): Don't use
 922         ungetc-char-ready?, since we don't provide that function any
 923         more.  The unread-string function doesn't interact properly with
 924         any of the standard I/O functions anyway.  (Thanks to Andrew
 925         Archibald.)
 926
 927         * hcons.scm (hashq-cons-assoc): Don't assume the empty list is
 928         false.  Return false when we cannot find a matching entry in the
 929         list.  (Thanks to Andrew Archibald.)
 930
 931 1998-07-16  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 932
 933         * boot-9.scm (export, export-syntax): New special forms: Export
 934         bindings from a module.  `(export name1 name2 ...)' can be used at
 935         the top of a module (after `define-module') to specify which names
 936         should be exported.  It can be used as an alternative to
 937         `define-public'.  `export-syntax' works equivalently to `export'
 938         but is intended for export of syntactic keywords.
 939         (Thanks to Thien-Thi Nguyen.)
 940
 941 1998-07-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 942
 943         * boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.
 944
 945 1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 946
 947         * boot-9.scm: Let the user start in module `(guile-repl)' instead
 948         of module `(guile)'.  Also make sure that `(guile-repl)' uses
 949         suitable modules.  This change improves Guile stability
 950         substantially since bindings will only be copied from the root
 951         module: If the user redefines builtins in `(guile-repl)' it won't
 952         affect the internal operation of Guile itself.
 953
 954 1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 955
 956         * boot-9.scm (load-module): When loading files from within files
 957         themselves being loaded: Use the directory path of the file being
 958         loaded as root for relative filenames.  (After suggestion by
 959         Steven G. Johnson.)
 960
 961 1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 962
 963         * emacs.scm (emacs-load): New feature: Eval in specified module.
 964
 965 1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 966
 967         * readline.scm: Typo in regex module name.
 968
 969 1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 970
 971         * readline.scm (apropos-completion-function): regexp-quote text to
 972         be completed.
 973
 974 1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 975
 976         * debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.
 977
 978 1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 979
 980         * boot-9.scm: Check that (current-input-port) is a tty before
 981         enabling readline.  (Thanks to Michael N. Livshin.)
 982
 983 1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 984
 985         * boot-9.scm (use-syntax): Turned into a macro inorder to be
 986         similar in use to `use-modules'.
 987         Example: (use-syntax (ice-9 syncase)) will 1. load the module
 988         (ice-9 syncase), and, 2. install the procedure `syncase' as eval
 989         transformer.
 990         (internal-use-syntax): New procedure.
 991         (process-define-module): Use `internal-use-syntax'.
 992
 993 1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 994
 995         * Makefile.am (ice9_sources): Add emacs.scm.
 996
 997 1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 998
 999         * readline.scm: Use the new readline facilities: Add the
1000         possibility to control input and output ports; Add apropos
1001         completion.
1002
1003         * boot-9.scm: Antirevert Jim's readline code which he reverted
1004         19971027 and adapt it to the current readline interface.
1005
1006         * boot-9.scm (top-repl): Only enable readline if not using the
1007         Emacs interface; Only use repl prompt when using the readline port
1008         from repl-read.  (We don't want to see it when calling `read'.)
1009
1010         * boot-9.scm (remove-hook!): Parenthesis bug.
1011
1012 1998-05-11  Mikael Djurfeldt  <mdj@kenneth>
1013
1014         * boot-9.scm: Load readline module if readline is present.
1015
1016         * readline.scm (apropos-completion-function): New procedure:
1017         Symbolic completion.  (Thanks to Andrew Archibald!)
1018
1019 1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1020
1021         * boot-9.scm (process-define-module): Added keyword use-syntax.
1022
1023 1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1024
1025         * nonblocking.scm: Removed.  libguile is now inherently
1026         nonblocking through the use of scm_internal_select.
1027
1028         * emacs.scm: Removed use of nonblocking.scm.
1029
1030         * gwish.scm, gtcl.scm: Removed.  tcltk.scm has made these
1031         obsolete.
1032
1033 1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>
1034
1035         * runq.scm (runq-control): Corrected spelling of enqueue!.
1036         (Thanks to Karl M. Hegbloom.)
1037
1038 1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>
1039
1040         * boot-9.scm: Added new run-time option interface eval-options.
1041
1042 1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1043
1044         * boot-9.scm (remove-hook!): New macro.  (Thanks to Maciej
1045         Stachowiak.)
1046
1047 1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1048
1049         * threads.scm: Added simple error and signal handler.
1050         (make-thread, begin-handler): Use this handler.  The most
1051         important effect of this is that signals get unmasked.
1052         Previously, when a signal was thrown signals remained masked
1053         (signals get masked when a signal is taken) which influenced other
1054         threads.
1055
1056 1998-01-01  Tim Pierce  <twp@skepsis.com>
1057
1058         A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
1059         * slib.scm (identity): Unmake public.
1060         (slib:eval): Evaluate inside `slib-module'.
1061
1062 1997-12-24  Tim Pierce  <twp@skepsis.com>
1063
1064         * boot-9.scm: Doc fix.
1065
1066         * slib.scm (identity): Made public.
1067         (home-vicinity): New function (from SLIB/Template.scm).
1068
1069 1997-12-13  Tim Pierce  <twp@skepsis.com>
1070
1071         * boot-9.scm (read-line): Rewritten to call %read-line for
1072         improved speed.  Minor user-visible changes: the new functions are
1073         hardwired to treat the LFD character as signifying end-of-line, so
1074         changing `scm-line-incrementors' will no longer affect the
1075         behavior of read-line.  On platforms which do not represent
1076         end-of-line with a LFD character, read-line should behave more
1077         like native line-processing facilities, but there is still a ways
1078         to go here.
1079
1080 Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>
1081
1082         * boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
1083         is now a fluid.
1084
1085 1997-11-28  Tim Pierce  <twp@skepsis.com>
1086
1087         * boot-9.scm (find-and-link-dynamic-module): If a module directory
1088         contains a .la file (a libtool support file), attempt to extract
1089         the shared library name from that file.  If the .la file does not
1090         exist, try to link against a .so file.  Libtool-generated compiled
1091         modules should load more cleanly in Guile now.
1092         (try-using-libtool-name, try-using-sharlib-name): New functions.
1093
1094 Sun Nov  9 06:10:59 1997  Gary Houston  <ghouston@actrix.gen.nz>
1095
1096         * boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
1097         usefully so they will work from a script.
1098
1099 1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>
1100
1101         * boot-9.scm (inherit-print-state): Moved definition to the
1102         neighborhood of the record code.
1103
1104 Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1105
1106         * boot-9.scm: Revert changes to this file from Oct 23.  It turns
1107         out to interact badly with the Emacs support and the Tcl/Tk
1108         support.  It's not a high enough priority at the moment to be
1109         worth fixing.  I'm leaving the other readline support in, though.

1113         * Makefile.am: Include readline.scm in the list of files to be
1114         installed, so Guile can find it for interactive use.

1118
1119         Add support for readline function.
1120         * readline.scm: New module.
1121         * boot-9.scm (repl-reader): New function.
1122         (scm-style-repl): Call repl-reader, instead of doing the reading
1123         ourselves.  Remove repl-report-reset; it was never used for
1124         anything.
1125         (top-repl): If we've got the readline primitives, then redefine
1126         repl-reader to use them.
1127         If we've got the readline primitives, import the readline module.
1128
1129         * ls.scm (ls, lls): Don't assume (eq? #f '()).
1130

1137
1138         * expect.scm: (expect-regexec): new procedure, use it in
1139         expect-strings to fix the => syntax under the new regex system.

1146         (set-batch-mode?!, batch-mode?): new closures, defined in
1147         error-catching-loop.  the names are from scsh.

1162         set-struct-printer-in-vtable!, *struct-printer*): Removed.
1163         (record-type-vtable, make-record-type): Don't use make-struct-printer.
1164         (record-type-vtable): User fields "prpr" (printer is no longer a

1174
1175         Suggestion and script from Maciej Stachowiak:
1176         * boot-9.scm: Split off modules into separate, autoloadable files.
1177         This reduces startup time from 10.5s to 5.5s (user cpu).
1178         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1179         string-fun.scm: New files, containing stuff that used to be in
1180         boot-9.scm.
1181         * Makefile.am (ice9_sources): List new files here, for
1182         distribution and installation.
1183         * Makefile.in: Regenerated.

1190
1191         * slib.scm (slib:load): slib:load first tries to load the file
1192         named NAME, then NAME.scm.  On error, report the error occuring at
1193         the first attempt (NAME) rather than the second (NAME.scm).
1194
1195         * boot-9.scm: Bugfix: Hard-solder the print-option procedure into
1196         the make-options macro so that we needn't refer to a global
1197         symbol.
1198
1199 Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

1208         separate-fields-after-char, separate-fields-before-char): Call
1209         continuation function, RET, as advertised: with each separated
1210         field a separate argument.
1211
1212         * Makefile.in: Regenerated with automake 1.2a.
1213

1217
1218         * boot-9.scm (in-vicinity): Bugfix: Don't add "/" to an empty

1228         * boot-9.scm (keyword->symbol, display-usage-report): Changed
1229         length --> string-length.  (Thanks to Aleksandar Bakic.)
1230         (separate-fields-discarding-char, separate-fields-after-char,
1231         separate-fields-before-char): Bugfix from Maciej Stachowiak
1232         <mstachow@mit.edu>.  Thanks!
1233         (try-module-linked): Try to find module among those already
1234         registered.
1235         (try-module-dynamic-link): Removed the first test which
1236         corresponds to a call to `try-module-linked'.
1237         (resolve-module): Resolve modules in this order: 1. Already
1238         registered modules (for example those which have been statically
1239         linked), 2. Try to autoload an .scm-file, 3. Try to dynamically
1240         link a .so-file.

1252
1253         * boot-9.scm (primitive-macro?): New procedure.
1254
1255         * slib.scm: Added hack which transfers syntactic information from
1256         the builtin variable `define' to the slib version if module (ice-9
1257         syncase) has been loaded.  This is necessary to get correct
1258         expansion inside the slib module.
1259
1260         * psyntax.ss (build-let, build-named-let): New output

1268         and eval-syntactic-expanders-when arguments.
1269
1270         * syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
1271         Should be used inside the (ice-9 syncase) module with (use-syntax
1272         syncase) and with the current directory containing the psyntax.ss
1273         source.
1274         Added hack to transfer syntactic information from the builtin
1275         variable `define' to the slib version if module (ice-9 slib) has
1276         been loaded.
1277
1278 Fri Sep  5 05:47:36 1997  Mikael Djurfeldt  <mdj@faun.nada.kth.se>

1287         (module-transformer, set-module-transformer!): Selector and
1288         mutator for module-associated transformer.
1289         (set-current-module): Use module-transformer to set
1290         `scm:eval-transformer'.
1291         (module-use!): Previous change reverted.
1292         (use-syntax): New function: Install a transformer in current
1293         module.
1294         (sc-interface, sc-expand): Removed! :)
1295
1296 Fri Sep  5 03:09:09 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1297
1298         * emacs.scm (emacs-load): Added new parameter `module'.
1299
1300         * syncase.scm (putprop, getprop): Modified to use the object
1301         properties of the variable object corresponding to the symbol;
1302         This way we can ride on the mechanisms of the module system.
1303         Changed `builtin-variable' calls to `define-public' calls.
1304         Setup the hooks sc-expand and sc-interface.
1305
1306         * boot-9.scm (sc-interface, sc-expand): New builtin variables.
1307         (set-current-module): Switch to and from sc-expand as
1308         scm:eval-transformer when going into and out of modules using
1309         syncase macros.
1310         (module-use!): Set scm:eval-transformer to sc-expand when adding
1311         the syncase interface.

1314
1315         * syncase.scm (putprop): Temporary fix which publishes new syntax
1316         globally (the old behaviour was complex and connected to the inner
1317         workings of the current module system).
1318
1319 Wed Sep  3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1320
1321         * psyntax.ss: Updated.
1322         psyntax.pp: Bugfix: Previous version had some leading "t":s cut

1332
1333         * gtcl.scm (make-tcl-binder): Rewritten to choose bindings
1334         according to the following priorities:
1335         1. tcl bindings which are present in override-scheme-list
1336         2. bindings from the-scm-module
1337         3. tcl bindings
1338         This way the gtcl module can occur first in the use-list without
1339         disabling the scheme interpreter.
1340         (new-interpreter): New function.
1341
1342         * gwish.scm: Moved initialization code for the-interpreter to
1343         gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
1344         it; Call `new-interpreter'; Don't :use-module (guile).

1361
1362         * session.scm (apropos-internal): Musn't initialize symbol
1363         accumulator with a constant pair.  That led to mutation of the
1364         source!
1365
1366 Sun Aug 24 01:03:10 1997  Mikael Djurfeldt  <mdj@kenneth>

1374         number (as displayed in the backtrace) to frame index (to be used
1375         in stack-ref).
1376
1377         * emacs.scm (emacs-load): New arguments: interactivep: when
1378         non-false, send back results to Emacs; colnum: Column number;
1379         Use modules (ice-9 debug) and (ice-9 session);
1380         (no-stack, no-source): New simple-actions;
1381         (result-to-emacs): New procedure. Sends data to Emacs via the
1382         result protocol;

1397
1398         * syncase.scm: Don't tamper with debug mode setting when enabling
1399         macros.  Instead cut the stack with start-stack.
1400         Load psyntax.pp with recording of positions turned off.
1401
1402         * psyntax.pp, psyntax.ss (quasiquote): Changed fx= --> =.

1419
1420         * emacs.scm (emacs-load): Something has changed in the reader so
1421         that we now should set the port line count to the specified value
1422         (linum) instead of (- linum 1).
1423
1424         * slib.scm (slib:load): Use load-from-path instead of
1425         primitive-load-path so that backtraces get narrowed properly at
1426         the top.

1447
1448         * slib.scm (install-require-module): In newer versions of slib
1449         *catalog* is #f until the first access.  Therefore we call

1455         automatically.
1456
1457 Mon Jul 21 06:45:45 1997  Gary Houston  <ghouston@actrix.gen.nz>
1458
1459         * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
1460         dup, fdes->inport, fdes->outport, port->fdes): new procedures.
1461         (duplicate-port): was a C primitive, now it's here.
1462         (move->fdes): allow the first argument to be a file descriptor.
1463         Return the modified port or file descriptor (was unspecified.)
1464
1465 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
1466
1467         Changes to compile under gnu-win32, from Marcus Daniels:
1468         * boot-9.scm (load-user-init): If HOME is unset, provide
1469         a default of /.
1470
1471         * boot-9.scm (define-public): Changed to accomodate Hobbit.
1472
1473 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
1474
1475         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
1476         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
1477         notation, instead of #/ notation.
1478
1479         * expect.scm (expect-strings): Pass regexp/newline flag to
1480         make-regexp.
1481
1482 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
1483
1484         Fix inconsistencies in parsing of #/ style lists.
1485         * boot-9.scm (read-path-list-notation): New function.
1486         (parse-path-symbol): Deleted.  Replaced by above.
1487         Plug in read-path-list-notation as the parser for #/ lists,
1488         instead of the anonymous lambda form calling parse-path-symbol.
1489         (Thanks to Maurizio Vitale.)
1490
1491         * boot-9.scm (make-list): Remove the definition of this function
1492         from the (ice-9 common-list) module; make the `init' argument
1493         optional in the scm module's definition, to match the deleted
1494         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
1495
1496 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
1497
1498         Try to detect when people are using one version of libguile and a
1499         different version of ice-9.  People have been skewing things and
1500         sending in bug reports.
1501         * version.scm.in: New file, which the configure script munges to
1502         produce version.scm, which contains the ice-9 config stamp.
1503         * boot-9.scm: Compare the libguile and ice-9 config stamps;
1504         display a warning if the two are different.
1505         * Makefile.am: Install version.scm, but don't distribute it.
1506         Distribute version.scm.in, but don't install it.
1507         * Makefile.in: Regenerated.
1508
1509 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
1510
1511         * slib.scm (slib:warn): Alias for WARN function.
1512
1513 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
1514
1515         * boot-9.scm (struct-printer): Fix off-by-one error in range
1516         check.  Correctly check for struct printer tag.
1517
1518         * expect.scm: Turn this into a module, (ice-9 expect).
1519         (expect-port, expect-timeout, expect-timeout-proc,
1520         expect-eof-proc, expect-char-proc, expect, expect-strings,
1521         expect-select): Make these public definitions.
1522         (expect-strings): Use make-regexp and regexp-exec, instead of
1523         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
1524         that's okay.
1525
1526         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
1527         users in the core, and relies on mildly hairy details of the old
1528         regexp interface.
1529
1530         * test.scm: Re-enable tests asserting that '() is true, and not a
1531         boolean.  This stuff has been true for a while.
1532
1533         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
1534         function names.
1535
1536         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
1537         fixes.
1538
1539 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
1540
1541         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1542         ../configure.in.
1543
1544 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1545
1546         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
1547         vtable and not the one of the struct.
1548
1549 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1550
1551         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
1552         make-struct-printer, set-struct-printer-in-vtable!): New bindings
1553         to support printing of structures.
1554         (record-type-vtable, make-record-type): Add slot to hold printing
1555         function and initialize it with something appropriate.  Removed
1556         commented out printing code.
1557         (record-type-name, record-type-fields): Adjusted slot offsets.
1558         (%print-module): Reduce argument list to "mod" and "port".
1559
1560 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1561
1562         * slib.scm (identity): New function, used by SLIB.
1563
1564 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
1565
1566         * boot-9.scm: signal-handler, alarm-thunk: removed.
1567         don't define ticks-interrupt etc.
1568         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
1569         during call to scm-style-repl.
1570
1571 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
1572
1573         * slib.scm (slib:load): Use primitive-load-path instead of
1574         basic-load.  This is probably wrong, but hopefully the entire
1575         source access system will be revised soon anyway, and this will
1576         make require behave more like Emacs Lisp's require.  If this
1577         breaks something, please let me know.  Maybe this is real dumb.
1578
1579 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
1580
1581         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
1582         * boot-9.scm: If the `regex' feature is present, use the module
1583         (ice-9 regex).
1584
1585 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
1586
1587         * regex.scm: New file.
1588         * Makefile.am (subpkgdata_DATA): Add regex.scm.
1589         * Makefile.in: Regenerated.
1590
1591 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1592
1593         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,

1601         in 1997.
1602
1603 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
1604
1605         * expect.scm: use gettimeofday instead of get-internal-real-time
1606         and use a floating point timeout when calling select.  Untested,
1607         since the regex library is currently AWOL.
1608
1609 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
1610
1611         * boot-9.scm (eval-string): Function deleted; it was already
1612         implemented in C, so there's no point in making a divergable copy
1613         here.
1614
1615 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
1616
1617         * Makefile.in: Regenerated, using automake-1.1p.

1624
1625         * boot-9.scm (error-catching-loop): don't read a line from
1626         current input when quit is encountered, the previous change
1627         fixes this too.
1628
1629 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
1630
1631         * boot-9.scm (scm-style-repl): After reading an expression,
1632         consume any trailing newline (perhaps preceded by whitespace), to
1633         avoid screwing up GDB.  More detail in comments.
1634
1635 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
1636
1637         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
1638         the Scheme code like code yet.
1639         * Makefile.in: Resrac,husrched.
1640
1641 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1642
1643         * boot-9.scm (link-dynamic-module): Do not catch errors from
1644         dynamic-link and dynamic-call.  When the shared library exists it
1645         is now assumed to be suitable for a dynamic C module.
1646
1647 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1648
1649         * boot-9.scm (process-use-modules): New function to support the
1650         use-modules macro
1651         (use-modules): throw an error iff one of the requested modules
1652         can't be found.
1653
1654 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
1655
1656         * boot-9.scm: don't define timer-thunk or gc-thunk.

1658 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
1659
1660         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1661
1662         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
1663         we're not using AM_INIT_GUILE_MODULE any more.
1664         * Makefile.in: Regeneratitetedrerd.
1665

1673         no plugins.
1674         * configure.in, configure: Removed.
1675         * Makefile.in: Regenerated.

1686 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
1687
1688         * expect.scm (expect-select): correct the millisecond timeout

1694         instead of in libguile.
1695         (tm:sec etc.) new accessors for broken-down time.
1696         (set-tm:sec etc.) new setters for broken-down time.
1697
1698 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1699
1700         * boot-9.scm (netent:addrtype, servent:port): added missing
1701         procedures.

1706
1707         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
1708         sockaddr:port): new functions.
1709
1710 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
1711
1712         * boot-9.scm: define accessor procedures for the objects returned
1713         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
1714         passwd:name, where the first component is the name of the C structure
1715         and the second is the unprefixed C member name.)
1716
1717 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
1718
1719         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
1720         setservent): no longer take an argument, it was bogus.
1721

1729         keywords and symbols.
1730
1731 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>

1754
1755         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
1756
1757 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
1758
1759         * boot-9.scm: check use-emacs-interface for emacs support.
1760
1761 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
1762
1763         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
1764         read gets EOF.
1765         * (exit): alias for quit.
1766
1767 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
1768
1769         * boot-9.scm (error-catching-loop thunk): use a status variable to
1770         return the quit args.
1771         (scm-style-repl): call -quit, passing return value from
1772         error-catching-repl.  Make -quit return its args.

1774
1775         (error-catching-loop thunk): discard trailing junk after a (quit).
1776

1783
1784         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
1785         Removed. These definitions are already present in r4rs.scm.
1786
1787         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
1788         stack before printing traced frames; Re-enable trace flag at end
1789         of handlers.

1797         Change hooks to use these functions.
1798
1799         * debug.scm: *Warning* This feature is a bit premature.  I add
1800         it anyway because 1. it is very useful, and, 2. you can start
1801         making it less premature by complaining to me and by modifying
1802         the source! :-)
1803         (trace): Given one or more procedure objects, trace each one.
1804         Given no arguments, show all traced procedures.
1805         (untrace): Given one or more procedure objects, untrace each one.
1806         Given no arguments, untrace all traced procedures.  The tracing in
1807         Guile have an advantage to most other systems: We don't create new
1808         procedure objects, but mark the procedure objects themselves.
1809         This means that also anonymous and internal procedures can be
1810         traced.
1811
1812         * boot-9.scm (error-catching-loop): Added handling of apply-frame
1813         and exit-frame exceptions.
1814
1815         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
1816         (set-repl-prompt!): Setter for repl prompt.
1817         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
1818         string, display it; if prompt is a thunk, call it and display its
1819         result; otherwise display "> ".
1820         (Change suggested by Roland Orre <orre@nada.kth.se>.)
1821
1822         * r4rs.scm (%load-verbosely): Reverted change to
1823         `module-defined?', since the module system isn't bootstrapped when
1824         we load r4rs.scm.  This is just a temporary fix to make the
1825         repository version runnable.
1826
1827 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1828
1829         * boot-9.scm: Removed the enabling of debug evaluator and
1830         recording of source code positions.  This was placed there for our
1831         convenience, but it has already sneaked into the distribution
1832         once... so we'd better add this in our local copies instead when
1833         we need it.  (These options are normally enabled at the end of
1834         boot-9.scm when loading the debug module.)
1835
1836 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1837
1838         * boot-9.scm (module-defined?): New function.
1839         (macroexpand-1, macroexpand): Use local-ref instead of defined?
1840         and eval.
1841         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
1842         "defined?".
1843         * slib.scm (defined?): New function to take the place of the
1844         builtin "defined?".  It allways examines the slib module.
1845
1846 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1847
1848         * configure.in: Added AM_MAINTAINER_MODE
1849
1850 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
1851
1852         * boot-9.scm (read-sharp): define directly, don't go through a
1853         %read-sharp layer.
1854
1855 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
1856
1857         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
1858         uniform-vector-set1! which doesn't exist.
1859
1860 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
1861
1862         * boot-9.scm (backtrace): Removed.  (A C version now exists in
1863         backtrace.c.)
1864
1865 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
1866
1867         * boot-9.scm (read-line!, read-delimited!, read-delimited,
1868         read-line): new procedures, see libguile/ChangeLog.
1869
1870 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1871
1872         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
1873
1874         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
1875         init-dynamic-module, dynamic-maybe-call,
1876         find-and-link-dynamic-module, link-dynamic-module,
1877         try-module-dynamic-link, registered-modules): New definitions for
1878         dynamic linking of modules.
1879         (resolve-module): Try to dynamically link the requested module
1880         after failing to load it as Scheme code.
1881
1882 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
1883
1884         * boot-9.scm (getservbyport, getservbyname): remove stray %.
1885
1886 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
1887
1888         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
1889         that's what it is.
1890
1891         * lineio.scm (make-line-buffering-input-port): Properly test for
1892         the case of an empty buffer list.  The old code assumed that '()
1893         was false.
1894
1895 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
1896
1897         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
1898         (use-modules <module name> ...) Put the the modules named by
1899         <module name> ... on the use list of the current module.
1900
1901 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
1902
1903         * boot-9.scm (error-catching-loop): Remove message saying that
1904         typing "$" will put you in the debugger.  This isn't implemented
1905         yet.
1906
1907 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
1908
1909         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
1910         been fixed, so this function is superfluous.
1911         (transform-usage-lambda): Use delq!, not delq-all!.
1912
1913 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
1914
1915         * boot-9.scm (resolve-module): New optional parameter that
1916         controls whether autoloading is attempted or not. Default is #t.
1917         (process-define-module): Don't autoload the defined module.
1918         (try-module-autoload): Don't autoload the directory modules.
1919
1920         * boot-9.scm (process-define-module): Ensure that the-scm-module
1921         is last in the `uses' list to allow shadowing builtin
1922         bindings. All :use-module options are added in the order they
1923         appear in the arguments but before anything already on the list
1924         (such as the-scm-module).
1925
1926 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
1927
1928         * slib.scm (slib-parent-dir): throw error if #f returned from
1929         %search-load-path.
1930
1931 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
1932
1933         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
1934         * Makefile.am, aclocal.m4: New files.
1935         * configure.in: Updated for Automake.
1936
1937 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
1938
1939         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
1940         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
1941         function, use it accordingly.
1942
1943 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
1944
1945         It's an "eval closure", not an "eval thunk."  A thunk is a
1946         function of no arguments.
1947         * boot-9.scm (module-type): Rename module field.
1948         (make-module, eval-in-module, make-root-module,
1949         set-current-module): Uses changed.
1950         (module-eval-closure, set-module-eval-closure!,
1951         root-module-closure): Renamed from module-eval-thunk,
1952         set-module-eval-thunk!, root-module-thunk.
1953         (set-current-module): Change uses of *top-level-lookup-thunk* to
1954         *top-level-eval-closure*.
1955
1956 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1957
1958         * slib.scm (slib-parent-dir): Use string-length, not length.
1959         (Thanks to Bernard Urban.)
1960
1961 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1962
1963         * boot-9.scm: The debugging evaluator and recording of positions
1964         aren't enabled by default any longer (they are switched on in
1965         debug.scm).  But during development we want to have them also
1966         *inside* boot-9.scm.  Therefore, two lines are added at the
1967         beginning of boot-9.scm to enable these.
1968
1969         Call `provide' so that `records' are included among the
1970         `*features*'.
1971
1972         The scheme for saving the stack has been adjusted: save-stack is
1973         now commonly available for saving the stack.  Calling `save-stack'
1974         sets a flag `stack-saved?' which prevents overwriting the stack.
1975         `stack-saved?' is reset at `abort'.
1976
1977         Spelling correction: seperate --> separate.
1978
1979         Removed `:'s that had creeped into some comments.
1980
1981         The repl now doesn't print #<unspecified> results any longer
1982         If the user wants to see this, he can do
1983         (assert-repl-print-unspecified #t) in his startup file.
1984
1985         The user now gets a friendly message instead of a backtrace at
1986         error.
1987
1988         Added `before-read-hook'.
1989
1990         Load module (ice-9 emacs) if option `-e' was specified.
1991
1992         (provide): New function.
1993
1994         (error): Save stack at entry, so that Guile entrails won't show up
1995         in backtraces.
1996
1997         (backtrace): New function.
1998
1999         (save-stack): Can now take arbitrary number of stack narrowing
2000         specifier pairs.  The first specifier in a pair controls inner
2001         border, the second the outer border.  A number means cut that
2002         number of frames, a procedure object means cut until that object
2003         is found in operator position in a frame.
2004
2005         * debug.scm: Enable debugging evaluator and recording of positions
2006         by default.
2007
2008         * slib.scm (slib:load): Adapt to the new behavior of
2009         primitive-load: It doesn't any longer try both with and without
2010         ".scm" extension.  (We don't want to use %search-load-path here.)
2011
2012         (implementation-vicinity): New function.  slib requires it
2013
2014         (library-vicinity): Updated.
2015
2016         Load "require.scm" in the library-vicinity.
2017
2018         (install-require-vicinity, install-require-module): New functions.
2019
2020 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
2021
2022         * boot-9.scm (load-from-path): New function.
2023
2024         * boot-9.scm (try-load, basic-try-load, try-load-module,
2025         try-load): Deleted.  I don't think they're being used.
2026
2027         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
2028         so they'll get distributed.
2029
2030         Get Guile to be a little less chatty by default.  The new user
2031         should see as little clutter as possible.
2032         * r4rs.scm (%load-verbosely): Make this #f by default.
2033         * boot-9.scm (scm-repl-verbose): Make this #f by default.
2034         (scm-style-repl): Don't run 'pk' on the value passed to quit.
2035
2036         * r4rs.scm: New file.
2037         * boot-9.scm: Load r4rs.scm, first thing.
2038         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
2039         open-output-file, open-io-file, close-input-port,
2040         close-output-port, close-io-port, call-with-input-file,
2041         call-with-output-file, with-input-from-port, with-output-to-port,
2042         with-error-to-port, with-input-from-file, with-output-to-file,
2043         with-error-to-file, with-input-from-string, with-output-to-string,
2044         with-error-to-string, the-eof-object): Definitions moved to
2045         r4rs.scm.  Not all of them are R4RS, but those that are use those
2046         that are not.
2047         (load, %load-verbosely, %load-announce): Moved, along with code to
2048         set %load-hook, to r4rs.scm.
2049
2050         * test.scm: New file.
2051
2052         * boot-9.scm (integer?): Definition deleted, in favor of the one
2053         present in libguile (which used to be called int?).  I have no
2054         idea why integer? didn't just call int? to begin with.
2055
2056         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
2057         =?, >?, and >=? deleted; they're defined that way by libguile now.
2058
2059         * boot-9.scm (load): Simplified; primitive-load does most of this
2060         work now.
2061         (%load-announce-win): Removed; no longer used.  Set %load-hook to
2062         call %load-announce.
2063
2064 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
2065
2066         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
2067         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
2068         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
2069         components.
2070         (file-is-directory?): use stat:type.
2071
2072 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
2073
2074         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
2075         that's now taken care of in libguile, and in a way compatible with
2076         SCSH (which this isn't).
2077
2078 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2079
2080         * boot-9.scm: Formatting tweaks.
2081
2082 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2083
2084         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
2085         after-error-hook, before-backtrace-hook and after-backtrace-hook
2086         to the error handler.  E.g.: fancy emacs support could plug into
2087         these.
2088         (save-stack): New function.  The stack is now made differently
2089         depending on the stack id.  (The motivation is to make a better
2090         choice regarding what stack frames to present to the user.)
2091         (error-catching-loop): Stack handling code moved outside into
2092         save-stack.
2093
2094 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
2095
2096         * Makefile.in (scm_files): add expect.scm.
2097
2098         * expect.scm: new file ported from guile-iii.
2099
2100         * boot-9.scm: remove handle-system-error, after moving the code into
2101         error-catching-loop.
2102         Don't set 'throw-handler-default property on error keys.
2103         Just interpret (almost) any throw with 4 args as an error throw.
2104         Delete some try-load stuff that was already commented out.
2105
2106         Second thoughts, keep handle-system-error but call it from
2107         error-catching-loop.
2108
2109 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
2110
2111         * boot-9.scm: Doc fixes.
2112         (make-module): Rework for readability.
2113         (make-root-module, make-scm-module): USES argument to make-module
2114         should be '(), not #f.
2115
2116         * boot-9.scm (try-load): %sys-load-path has been renamed to
2117         primitive-load-path; adjust call here.
2118
2119 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2120
2121         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
2122         the stack to the correct place: when it is decided to generate an
2123         error-signal.
2124
2125 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2126
2127         * boot-9.scm (error-catching-loop, signal-handler,
2128         handle-system-error): Backtracing now works for signals aswell;
2129         Backtracing mechanism can now identify the stack root created by
2130         start-stack so that the user isn't exposed to system stack frames.
2131
2132 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2133
2134         * Makefile.in: Added threads.scm.
2135
2136 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2137
2138         * debug.scm (make-enable, make-disable): Simplified.
2139
2140         * boot-9.scm: Renamed %%throw-handler-default -->
2141         throw-handler-default.
2142         ((handle-system-error key . arg-list)): Changed the way errors are
2143         reported.
2144         ((scm-style-repl)): Wrap up the call to eval in a start-stack
2145         acro.
2146         ((error-catching-loop thunk)): Introduce a lazy-catch into
2147         error-catching-loop so that the stack can be captured.

2150
2151         * mapping.scm (hash-table-mapping): Explicitly request that
2152         make-vector fill new vectors with '(); this will make it easier to
2153         port Guile Scheme code to other Schemes.
2154         * boot-9.scm (make-print-style, make-print-table): Same.

2157
2158         * boot-9.scm (load): rewritten again.
2159         Append "." to the default %load-path.
2160         (feature?): new function: checks for a symbol in the features list.
2161         (module-local-variable): remove apparently useless (caddr (list m v
2162         ...))
2163         (%load-announce): minor formatting change.
2164         (file-exists?): use access? if posix is featured.
2165         (file-is-directory?): use stat if i/o-extensions is featured.
2166         (try-module-autoload module-name): use file-exists? before
2167         file-is-directory?
2168

2170
2171         * boot-9.scm: Added conditional loading of threads.scm.
2172
2173         * threads.scm: New file.  Modified from the Cygnus-r0.3
2174         distribution.
2175
2176         * boot-9.scm (error-catching-loop): Added handling of key
2177         `switch-repl'.
2178
2179         * boot-9.scm: Name change %%bad-throw --> bad-throw.
2180
2181 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2182
2183         * boot-9.scm (make-record-type, record-constructor): Don't assume
2184         the empty list is false when parsing the argument list.
2185
2186 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2187
2188         * boot-9.scm (signal-handler): Clean up logic.
2189
2190         * boot-9.scm (load): Assume %load-path is always bound.
2191
2192 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2193
2194         * boot-9.scm (error): replace another throw with scm-error.  Throw
2195         to 'misc-error instead of 'error (no need to distinguish these.)
2196         Don't set up 'error as a key.
2197         Set up regex-error as a key, if regex is available.
2198         (signal-handler): use scm-error, not throw.
2199
2200         (%try-load, try-load-with-path, %load, load-with-path,
2201         basic-try-load-with-path, basic-load-with-path,
2202         try-load-module-with-path,load-module-with-path): deleted, since
2203         they seem redundant.
2204         (try-load): define using %try-load, not try-load-with-path.
2205         (load): rewritten.  load tries to open the file directly and
2206         with a .scm extension before searching the library directories
2207         (should "." be added to %load-path?  then load could still open
2208         directly files starting with "/").
2209         (try-module-autoload): use load, not load-with-path.
2210         (%load-indent): deleted, -2 was causing errors.
2211
2212         (%read-sharp): use port-line, not line-number.
2213
2214 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2215
2216         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
2217         straightforward to provide the equivalent functionality using
2218         (catch #t ...), so there's no need for the extra complexity.  2)
2219         Outside the context of a read-eval-print loop (which Guile should
2220         not require) it's not clear we should do anything more complicated
2221         than print an error and exit; the user or REPL can establish
2222         something better if it wants.  3) In that case, it's much more
2223         robust to just do it in the C code.
2224
2225 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
2226
2227         * boot-9.scm (%try-load): define using primitive-load.  Previously
2228         %try-load itself was the primitive.
2229         (load-with-path): use scm-error instead of %load-announce-lossage.
2230         Errors are thrown to 'misc-error instead of 'could-not-load.
2231         (%load-announce-lossage): deleted.
2232
2233 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
2234
2235         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
2236         (make-record-type type-name fields): Temporarily remove support
2237         for printing of records (not possible yet with C printer).
2238
2239 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
2240
2241         * boot-9.scm (file-exists?, file-is-directory): catch only
2242         system-error, not every kind of error.
2243         (scm-error): new procedure.
2244
2245 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2246
2247         * boot-9.scm: Formatting tweaks.
2248
2249 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2250
2251         * boot-9.scm (%%handle-system-error key): remove the code for
2252         SCM-style errors.  handle the case that an unexpected number
2253         of args are supplied.
2254         (%%system-errors): removed.
2255         (error): redefine using a throw with key and 4 args.
2256         ('error): associate 'error, 'error-signal keys with
2257         %%handle-system-error.
2258         (%%default-error-handler): removed.
2259         (signal-handler): throw with 4 args and use the error-signal key.
2260         Create an error message instead of using numerical codes.
2261         (%%bad-throw): call error instead of throw if key not found.
2262
2263 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
2264
2265         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
2266         (%%handle-system-error key): check subr is not #f before printing.
2267         Recognize %s (embed an argument using "display") and
2268         %S (embed an argument using "write").
2269
2270 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
2271
2272         * boot-9.scm (%%handle-system-error key): set args and rest to
2273         the empty list if they are #f.
2274         Initialize out-of-range as an error key.
2275
2276 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
2277
2278         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
2279
2280         * boot-9.scm: remove leading %% from references to '%%system-error.
2281         (%%handle-system-error): don't pass all the thrown arguments when
2282         aborting, just the key and subr.
2283         Remove the code to "Install default handlers for built-in errors."
2284         Remove the definition of the syserror procedure.
2285         Associate 'numerical-overflow with default handler.
2286
2287 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2288
2289         * boot-9.scm: Name change: value-ref --> local-ref
2290         resolved-ref --> nested-ref  Motivation: conformance to the other
2291         dictionary operators: list-ref operates on list, vector-ref
2292         operates on vector, nested-ref operates on nested namespace,
2293         local-ref operates on the local nested namespace.
2294
2295 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
2296
2297         * boot-9.scm (%%handle-system-error): recognise errors thrown
2298         by lgh-error (fill-message etc.)
2299         (fill-message): check first whether args is null.
2300         (fill-message): bug fix and check that args is a list.
2301
2302 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
2303
2304         * boot-9.scm: %load-path is initialized in C code now.
2305         (implementation-vicinity, parse-path): Deleted, along with code to
2306         initialize %load-path.
2307
2308         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
2309         "/", use one to separate it from the file.
2310
2311 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
2312
2313         * boot-9.scm (%load-path): Add the site directory.
2314         Add the directory named after the version number.
2315         Prepend the version number to the other directories in the path.
2316         Simplify by mapping the common prefix onto each item.
2317         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
2318         sitedatadir): New definitions.

2325
2326         Don't use the PLUGIN system to gather information for the
2327         Makefile's distribution and installation targets; just put it all
2328         in the Makefile directly.
2329         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
2330         for these.
2331         * configure.in: Remove code that gets and substitutes scm_files and
2332         aux_files.

2334         here, where people expect to find them.

2369         (manifest): Deleted.
2370         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a

2372
2373 Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>
2374
2375         * boot-9.scm: remove the wrappers for '%' system primitives,

2379
