   4
   5 2000-08-16  Marius Vollmer  <mvo@zagadka.ping.de>
   6
   7         * optargs.scm: Replaced `#&' reader syntax with keywords.
   8
   9 2000-08-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  10
  11         * format.scm (format:obj->str): Made tail-recursive.  (Thanks to

  13
  14 2000-08-13  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
  15
  16         * psyntax.ss (top-level-eval-hook, local-eval-hook): Pass
  17         `(interaction-environment)' as second arg to `eval'.  This is
  18         completely equivalent with the state before the change to eval of
  19         2000-08-11, but we should extend psyntax.ss to be module aware.
  20         (Thanks to Ian Bicking.)
  21
  22         * emacs.scm (emacs-symdoc): Parenthesis fix.
  23
  24 2000-08-11  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
  25
  26         * r5rs.scm (interaction-environment): Removed definition.  (Is now
  27         provided by libguile/modules.c.)
  28
  29         * safe-r5rs.scm (null-environment): Bugfix: Should include
  30         syntactic bindings.
  31
  32         * boot-9.scm (record-constructor, record-accessor,
  33         record-modifier, scm-style-repl): Add second arg to eval.
  34         (read-hash-extend #\.): Ditto.  (This is actually a bugfix!)
  35         (eval-in-module): Redefined to be eval and deprecated.
  36
  37         * syncase.scm (eval): Add second arg both in definition and use.

  40         (defmacro:eval): Eval in (interaction-environment).
  41
  42         * safe-r5rs.scm (eval): Removed definition.
  43
  44         * emacs.scm (emacs-eval-request):
  45         (emacs-symdoc): (This procedure needs updating!)
  46
  47 2000-08-10  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
  48
  49         * boot-9.scm: Added note about dependency in modules.h to
  50         definition of module-type.
  51
  52         * Makefile.am (ice9_sources): Added receive.scm, srfi-8.scm.
  53
  54         * receive.scm, srfi-8.scm: New files.
  55
  56         * boot-9.scm (scm-style-repl): Print multiple values on successive
  57         lines.
  58         (process-define-module): Bugfix: Make sure that exports are done
  59         *after* all used interfaces has been added.

  62 2000-07-24  Marius Vollmer  <mvo@zagadka.ping.de>
  63
  64         * common-list.scm (uniq): Made tail-recursive.  Thanks to thi!
  65
  66 2000-07-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  67
  68         * boot-9.scm (expt):  In case of negative integer exponents return
  69         an exact result if the input paramters were exact.  Thanks to
  70         Mikael for the suggestion.
  71
  72 2000-07-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  73
  74         * boot-9.scm (expt):  Make sure that integer-expt is only called
  75         if the exponent is a non-negative integer.
  76
  77 2000-07-01  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  78
  79         * boot-9.scm (process-define-module): Bugfix: Only check the CDR
  80         for export args.
  81
  82 2000-06-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  83
  84         * popen.scm:  gc-thunk is deprecated.  Use after-gc-hook instead.
  85
  86 2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  87
  88         * common-list.scm (intersection, set-difference, remove-if,
  89         remove-if-not):  Made tail-recursive.  Thanks to William Webber
  90         for the hint.
  91
  92         (delete-if!, delete-if-not!):  Renamed parameter from `list' to
  93         `l' in order to avoid confusion.  Note:  These functions are not
  94         tail recursive yet.
  95
  96 2000-06-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  97
  98         * boot-9.scm: Turned `the-module', `*top-level-lookup-closure*',
  99         and `scm:eval-transformer' into fluids.
 100
 101         * boot-9.scm (purify-module!, module-export!): New procedures.
 102         (export): Rewritten using `module-export!'.
 103         (process-define-module): New define-module options: pure, export.
 104         See NEWS.
 105         (scm-style-repl): Added optional module argument.
 106
 107         * null.scm, r5rs.scm, safe-r5rs.scm, safe.scm: New modules.
 108
 109 2000-06-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 110
 111         * session.scm (make-fold-modules): Detect circular references in
 112         module graph.  (Thanks to Matthias Köppe.)
 113
 114 2000-06-20  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 115
 116         * session.scm: Use module (ice-9 regex).
 117         (help): Regexp-quote a name given as a symbol.
 118
 119 2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 120
 121         * common-list.scm (list*):  Removed, since this function is
 122         implemented as a primitive in libguile/list.c.
 123
 124 2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 125
 126         * session.scm (help): Warn user if 'regex isn't provided.
 127
 128         * Makefile.am (ice9_sources): Removed getopt-gnu-style.scm.
 129
 130         * getopt-gnu-style.scm: Removed deprecated module.
 131
 132 2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 133
 134         * boot-9.scm (make-autoload-interface): Set init value for uses to
 135         '() instead of #f.
 136         (make-modules-in): Name modules with their real (= full) names.
 137         (the-root-module, the-scm-module): Named `(guile)' instead of
 138         `the-root-module'.
 139         (the-scm-module): Set kind to 'interface.
 140
 141         * Makefile.am (ice9_sources): Replaced doc.scm with
 142         documentation.scm.
 143
 144         * session.scm (ice-9): Use module (ice-9 documentation).
 145         (name): Use the name property if everything else fails.
 146         (apropos-fold): New procedure.
 147         (apropos-internal): Re-implement in terms of `apropos-fold'.
 148         (help): Rewritten.
 149
 150         * doc.scm: Removed module (ice-9 doc).
 151
 152         * documentation.scm: New module (ice-9 documentation).
 153
 154 2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 155
 156         * doc.scm (documentation-files): Renamed from `doc-files'.
 157         (write-all): Removed.
 158         (find-documentation): Renamed from `documentation'.  Return
 159         documentation string instead of printing it.  Not exported.
 160
 161 Tue Jun  6 09:21:28 2000  Greg J. Badros  <gregb@go2net.com>
 162
 163         * session.scm: Update references to `proc-doc' to be
 164         `proc-documentation'
 165
 166         * doc.scm: Cleaned up a great deal.  Put variables at the top of
 167         the file, eliminated `object-documentation' that was broken
 168         (referencing Scwm), drop `help' as session.scm has a better
 169         supported version of that procedure. Rename `proc-doc' to
 170         `proc-documentation' -- `procedure-documentation' is a primitive
 171         getter function, so I use the shorter name for this more useful
 172         function.  (Alternatively, we could rename the primitive
 173         getter...)
 174
 175 2000-06-05  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 176
 177         * boot-9.scm (error-catching-loop): Inform about debugger on error.
 178
 179 2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 180
 181         * boot-9.scm (scm-module-closure): New procedure: Was previously
 182         anonymous.  Now needed in modules.c.
 183         (make-module): Use `standard-eval-closure' to create the eval
 184         closure.
 185
 186 2000-05-14  Gary Houston  <ghouston@arglist.com>
 187
 188         * boot-9.scm (load-user-init): rewritten.  first work out the home
 189         directory and then try to open the file (previously it could try
 190         to open a file in more than one place).  catch exceptions when
 191         trying to get a directory from the user database.  don't check
 192         that ~/.guile is not a directory before trying to load it (a lack
 193         of ~/.guile is not a crime, but if the file is not valid for any
 194         reason then primitive-load will raise an error).
 195
 196 2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 197
 198         * boot-9.scm (abs):  Don't set to magnitude.  abs now does not
 199         accept complex numbers as parameter.
 200
 201 2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
 202
 203         * common-list.scm (delete-if-not!): Bug fix of bug fix: change
 204         label of named let to `delete-if-not'.  Sorry.
 205
 206 2000-05-08  Marius Vollmer  <mvo@zagadka.ping.de>
 207
 208         * common-list.scm (doc fixes): Talk about `true values' instead of
 209         `#t' when a function treats all non-#f valuers the same.
 210         (remove-if-not): Bug fix: call remove-if-not
 211         instead of remove-if when iterating.
 212         (delete-if-not!): Bug fix: call delete-if-not! instead of
 213         delete-if! when iterating.
 214
 215 2000-04-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 216
 217         * r4rs.scm (close-input-port, close-output-port): Removed.
 218
 219 2000-04-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 220
 221         * session.scm (help): New macro.  Prints helpful information.
 222
 223 2000-04-10  Gary Houston  <ghouston@arglist.com>
 224
 225         * popen.scm (open-process): after forking, close all ports except
 226         the end of the pipe to the parent.  otherwise move->fdes and
 227         the exec'd program and the exit handlers can interfere with file
 228         descriptors still in use in parent ports.
 229
 230 2000-04-09  Gary Houston  <ghouston@arglist.com>
 231
 232         * popen.scm (close-process-quietly): new procedure.  use it from
 233         reap-pipes to avoid errors or hanging during background cleanup.
 234
 235 2000-04-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 236
 237         * format.scm (format:obj->str): Handle circular references.  Also,
 238         print improper lists with (x y . z) syntax rather than as
 239         individual pairs.  (This code should probably be integrated into C
 240         level facilities.  It is currently terribly slow.)
 241
 242 2000-04-03  Michael Livshin  <mlivshin@bigfoot.com>
 243
 244         * streams.scm (stream-fold, stream-for-each): don't use named let,
 245         because it prevents the gc from junking the stream argument.
 246
 247 Thu Mar  9 08:05:08 2000  Greg J. Badros  <gjb@cs.washington.edu>
 248
 249         * slib.scm: Back-out change to software-type -- renamed
 250         slib:software-type to software-type, and leave it non-public.
 251
 252 Thu Mar  2 12:20:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
 253
 254         * boot-9.scm: Drop unused definition of sfx function -- thanks
 255         Dirk Hermann!
 256
 257 Wed Mar  1 12:21:02 2000  Greg J. Badros  <gjb@cs.washington.edu>
 258
 259         * streams.scm: Doc patch from Richard Kim, using MIT Scheme as
 260         source of the numerous very short changes.
 261
 262 Sun Feb 13 18:03:19 2000  Greg J. Badros  <gjb@cs.washington.edu>
 263
 264         * slib.scm: Rename software-type to slib:software-type and make it
 265         public.
 266
 267         * r4rs.scm: Added documentation; largely cut and pasted from R4RS
 268         info pages.
 269
 270 Sun Feb 13 17:49:29 2000  Greg J. Badros  <gjb@cs.washington.edu>
 271
 272         * common-list.scm: Added documentation; largely cut and pasted
 273         from slib docs.
 274
 275 2000-02-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 276
 277         * format.scm (format): Reintroduce (define format format:format)
 278         so that the binding in the public interface of the module will be OK.
 279
 280 2000-01-30  Gary Houston  <ghouston@arglist.com>
 281
 282         * boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
 283         to string-append.
 284
 285 2000-01-29  Gary Houston  <ghouston@arglist.com>
 286
 287         * expect.scm (expect): don't call char-ready? before expect-select,
 288         since select now checks port buffers itself.  don't bother to check
 289         the time first either, since expect-select does it.
 290
 291 Thu Jan 20 12:57:36 2000  Greg J. Badros  <gjb@cs.washington.edu>
 292
 293         * format.scm: Use (variable-set! (builtin-variable 'format)) to
 294         re-define format to be format:format (instead of just define,
 295         which interacts poorly with the module system).  Thanks to Shuji
 296         Narazaki for this change.
 297
 298 Tue Jan 11 10:49:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
 299
 300         * boot-9.scm expect.scm, syncase.scm: Switch to new style
 301         `simple-format' message strings: substitute ~A for %s, and ~S for
 302         %S.
 303
 304         * boot-9.scm:  Added (define format simple-format) to expose that
 305         primitive via the simpler name until format.scm is loaded.
 306
 307 2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
 308
 309         * boot-9.scm (try-using-libtool-name): Do not bother to look
 310         inside libtool ".la" file, dynamic-link does this for us now.
 311
 312 1999-12-15  Gary Houston  <ghouston@freewire.co.uk>
 313
 314         * slib.scm (library-vicinity, home-vicinity,
 315         scheme-implementation-type, scheme-implemenation-version):
 316         use define-public to export from the module.
 317
 318 Wed Dec 15 08:32:09 1999  Greg J. Badros  <gjb@cs.washington.edu>
 319
 320         * doc.scm: Use `%library-dir' and the other system directories,
 321         not the quickly defuncted `library-dir' that I added before
 322         realizing the former existed.  Thanks Brad Knotwell!
 323
 324 Sun Dec 12 19:18:52 1999  Greg J. Badros  <gjb@cs.washington.edu>
 325
 326         * Makefile.am, doc.scm: Added doc.scm.
 327
 328 1999-12-12 18:54:06 1999  Greg J. Badros  <gjb@cs.washington.edu>
 329
 330         * popen.scm, slib.scm: Added some docstrings for procedures that
 331         were primitives that I encountered in posix.texi.
 332
 333 1999-11-19  Gary Houston  <ghouston@freewire.co.uk>
 334
 335         * Makefile.am (ice9_sources): add arrays.scm.
 336
 337         * boot-9.scm: load arrays.scm if 'array is provided.
 338
 339         * arrays.scm: new file with stuff from boot-9.scm.
 340
 341 1999-11-18  Gary Houston  <ghouston@freewire.co.uk>
 342
 343         * boot-9.scm (read-hash-extend to set up arrays): add 'l' for
 344         long_long uniform vectors.
 345
 346 1999-11-17  Gary Houston  <ghouston@freewire.co.uk>
 347
 348         * networking.scm (sethostent, setnetent, setprotoent, setservent):
 349         take an optional argument STAYOPEN.  default is #f.
 350
 351 1999-10-05  Jim Blandy  <jimb@savonarola.red-bean.com>
 352
 353         * Makefile.in: Deleted from CVS repository.  Run the autogen.sh
 354         script to create generated files like this one.
 355
 356 1999-09-23  Gary Houston  <ghouston@freewire.co.uk>
 357
 358         * boot-9.scm (load-user-init): check that the posix feature is
 359         available before using getpw and getuid.
 360         (top-repl): don't install handlers for SIGINT etc., without posix.
 361         (file-is-directory?): use 'posix instead of i/o-extensions to
 362         check for stat.
 363         (load-user-init): use file-exists? and file-is-directory? to
 364         check for .guile, instead of stat.
 365         (file-is-directory?): don't display the file name if posix not
 366         available.
 367         (feature?): I guess this is deprecated.  redefined using "provided?"
 368         and changed users in boot-9.scm to "provided?".
 369         Conditionally load posix.scm and networking.scm.
 370
 371         posix.scm, networking.scm: new files.  Move definitions from
 372         boot-9.scm if they are only useful with posix/networking available.
 373
 374         * Makefile.am (ice9_sources): add posix.scm, networking.scm.
 375
 376 1999-09-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 377
 378         * debugger.scm (read-and-dispatch-commands): Handle other throws
 379         than 'exit-debugger.
 380
 381         * boot-9.scm (before-signal-stack): New fluid.
 382         (top-repl): Set before-signal-stack in the signal handler.
 383
 384         * debugger.scm (eval-handler): Handle unhandled exceptions.
 385
 386 1999-09-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 387
 388         * debugger.scm ("p"): New alias for "evaluate";
 389         Mark module with :no-backtrace.
 390         ("position"): New command.
 391         (source-position, display-position): New procedures.
 392         (display-source): Display position of expression, if available.
 393         (catch-user-errors): Return #f on error.  (Commands are expected
 394         to return a valid state.)
 395         (read-and-dispatch-command): Bugfix: Return old state on error.
 396
 397 1999-09-16  Jim Blandy  <jimb@savonarola.red-bean.com>
 398
 399         * regex.scm (regexp-substitute/global): Handle the end of the
 400         match list and an empty match list identically.  (Thanks to Greg
 401         Badros.)
 402
 403 1999-09-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 404
 405         * debugger.scm ("evaluate"): Replaced `write-line' with calls to
 406         `write' and `newline' since write-line doesn't write but displays.
 407
 408 1999-09-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 409
 410         * debugger.scm ("evaluate"): Newline after no env announcement.
 411
 412         * debug.scm, emacs.scm: Updated copyright notices.
 413
 414         * boot-9.scm (make-autoload-interface): Bugfix.

 418         display-backtrace if it wasn't explicitly given by the user.
 419         (write-frame-long/application): Also print corresponding source
 420         expression.
 421         ("evaluate"): Evaluate in local environment frame, if existent;
 422         Handle errors.
 423
 424 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 425
 426         * format.scm (format:format-work): Use #\tab and #\page instead of
 427         slib:form-feed and slib:tab.  (Thanks to Ceri Storey.)
 428
 429         * format.scm (format:abort): Call error, not slib:error.
 430
 431 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 432
 433         * boot-9.scm (using-readline?): New procedure: Returns #t if
 434         readline is used by the repl run by this thread.
 435         (handle-system-error): Print "Backtrace:" before backtrace since
 436         this is no longer done by display-backtrace.
 437
 438         * debug.scm (frame-number->index): Optionally take stack as
 439         argument.
 440
 441         * debugger.scm: Use the frame number abstraction which allows for
 442         both forward and backward views of the stack
 443         (write-frame-index-short, write-frame-index-long):
 444         Use selector `frame-number';
 445         (select-frame-absolute): Use frame-number->index.
 446         ("backtrace"): Use builtin backtrace printing.
 447         Use (ice-9 debug).
 448         Use readline conditionally.
 449
 450 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 451
 452         * regex.scm (fold-matches, list-matches): New functions.
 453         (regexp-substitute/global): Rewritten again in terms of
 454         list-matches, to get null match behavior correct.
 455
 456         * regex.scm (regexp-substitute/global): Rewrite so that 'post at
 457         the end of the item list actually causes a tail call.  (Thanks to
 458         Jan Nieuwenhuizen.)
 459
 460 1999-09-11  Marius Vollmer  <mvo@zagadka.ping.de>
 461
 462         * readline.scm: Moved to ../guile-readline.
 463
 464         * boot-9.scm (top-repl): Removed code for activating readline.
 465
 466         * Makefile.am: Removed mention of readline.scm.
 467
 468         * Makefile.in: Regenerated.
 469
 470 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 471
 472         Delete the test which compares the configuration date of libguile
 473         with the configuration date of ice-9.  This test yields too many
 474         false positives to be helpful.  For example, if you build Guile
 475         for several architectures but have them all share a "share"
 476         directory (which is supposed to work), then all but one
 477         architecture's Guile will complain that the configuration dates
 478         don't match.  Which is true, but indicates nothing wrong.
 479         * boot-9.scm: Delete code which compares ice-9-config-stamp with
 480         libguile-config-stamp.
 481         * version.scm.in: Delete.
 482         * Makefile.am (ice9_generated): Delete.
 483         (subpkgdata_DATA): Remove ice9_generated.
 484         (EXTRA_DIST): Remove version.scm.in.
 485         * Makefile.in: Regenerate.
 486
 487 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 488
 489         * debugger.scm: New file: Initial version of the Guile debugger
 490         written by Chris Hanson.  (The debugger isn't finished, but is
 491         included in Guile anyway since it is already quite useful.)
 492
 493         * boot-9.scm (top-repl): Use (ice-9 debug) (ice-9 debugger) (ice-9
 494         session) (ice-9 threads) (ice-9 regex) from guile-user only if
 495         top-repl is called.  This makes startup time for scripts 30% of
 496         what it was before...  Removed redundant code for loading of
 497         readline.
 498
 499         * Makefile.am (ice9_sources): Added debugger.scm.
 500
 501 1999-08-29  Keisuke Nishida  <kxn30@po.cwru.edu>
 502
 503         * boot-9.scm (try-module-autoload): Use %search-load-path.
 504
 505 1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 506
 507         * boot-9.scm: Removed old style hooks.
 508         (inherit-print-state): Rwwritten to use port-with-print-state.
 509
 510 1999-08-20  James Blandy  <jimb@mule.m17n.org>
 511
 512         Remove support for the #/ path list syntax entirely.
 513         * boot-9.scm (read-path-list-notation,
 514         read-path-list-notation-warning): Deleted.
 515         Don't register read-path-list-notation-warning as a reader for
 516         objects starting with '#/'.
 517
 518 1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 519
 520         GOOPS needs the observer protocol specified for the new module
 521         system.  Here's a simple version for the old module system:
 522         * boot-9.scm (module-observers, module-weak-observers,
 523         module-observer-id, set-module-observers!,
 524         set-module-observer-id!): New accessors.
 525         (module-type): Added slots `observers', `weak-observers' and
 526         `observer-id'.
 527         (module-observe, module-observe-weak, module-unobserve,
 528         module-modified): New procedures.
 529         (module-make-local-var!, module-add!, module-remove!,
 530         module-clear!, module-define!, module-use!): Call module-modified.
 531
 532 1999-07-29  Marius Vollmer  <mvo@zagadka.ping.de>
 533
 534         * boot-9.scm (error-catching-loop): Correct non-RnRS usage of internal
 535         defines.
 536
 537 1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>
 538
 539         * streams.scm: New module, contributed by Michael Livshin.
 540         * Makefile.am (ice9_sources): List it.
 541         * Makefile.in: Regenerated.
 542
 543         * boot-9.scm (read-delimited!): Put the terminator in the correct
 544         position.
 545
 546 1999-06-29  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 547
 548         * readline.scm: Bugfix: Avoid getting the continued-lines prompt
 549         at multiple calls to read.
 550         (promtp2): Variable for continued-lines prompt.
 551         (make-readline-port): Use prompt2.
 552         (set-readline-prompt!): New optional arg which sets
 553         continued-lines prompt.
 554
 555         * boot-9.scm (top-repl): Set/clear readline prompts before/after
 556         reading expressions.
 557
 558 1999-06-18  Jim Blandy  <jimb@savonarola.red-bean.com>
 559
 560         * ls.scm (ls, lls): Handle no arguments as meaning to look in
 561         `(current-module)'. (Patch from Thien-Thi Nguyen.)
 562
 563 1999-06-14  Jim Blandy  <jimb@savonarola.red-bean.com>
 564
 565         * string-fun.scm (split-before-predicate, split-after-predicate,
 566         split-discarding-predicate): Make these public.  (Thanks to
 567         Thien-Thi Nguyen.)
 568
 569         1999-06-13  Gary Houston  <ghouston@easynet.co.uk>
 570
 571         * more changes to expect.scm, to avoid the one-character lookhead
 572         that was introduced to fix the $ problem:
 573
 574         * expect.scm (expect): call the match proc an extra time at end
 575         of file and set the eof? argument appropriately.  call
 576         expect-eof-proc only if the last call didn't match.
 577         * expect.scm (expect-strings): change port to eof? in match proc.
 578         * expect.scm (expect-regexec): take an eof indicator as an argument
 579         instead of a port.
 580
 581 1999-06-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 582
 583         * Makefile.am (ice9_sources): Add popen.scm to list.
 584         * Makefile.in: Regenerated.
 585
 586         Fixes for expect from Gary Houston  <ghouston@easynet.co.uk>:
 587
 588         * expect.scm (expect-regexec): define 'eof-next?'.  I don't
 589         know why it was missing.  also don't peek for end of lines
 590         unless expect-strings-exec-flags contains regexp/noteol.
 591         (expect-strings-exec-flags): initialise to regexp/noteol.
 592
 593         Gary Houston's open-buffer port patches:
 594
 595         1999-04-01  Gary Houston  <ghouston@easynet.co.uk>
 596
 597         * popen.scm: applied fixes from Greg Harvey.  use a guardian
 598         and a gc-thunk so that cleanup is done if a pipe is garbage
 599         collected or closed with close-port.  use a weak hash-table instead of
 600         an alist.
 601
 602         1999-03-20  Gary Houston  <ghouston@easynet.co.uk>
 603
 604         * expect.scm (expect): call the match proc with the port instead.
 605         (expect-strings): use peek-char to get the next char.  this has
 606         the advantage of getting the handling of $ "correct", but the
 607         disadvantage of needing to get (and maybe block for) an extra character
 608         from the port when it may not be needed.  hence:
 609         (expect-strings-exec-flags): new variable/parameter, supplies
 610         flags for regexp-exec.  if this includes regexp/noteol, then
 611         automatic regexp/noteol handling (requiring an extra peeked char)
 612         is enabled.  default is regexp/noteol.
 613         (expect-strings-compile-flags): new variable/parameter, supplies
 614         flags for make-regexp.  default is regexp/newline.
 615
 616         1999-03-15  Gary Houston  <ghouston@easynet.co.uk>
 617
 618         * expect.scm (expect): call the match proc with an extra char,
 619         peeked from the stream.
 620         (expect-strings): build a match proc which takes the extra char.
 621         (expect-regexec): take an extra arg "eof-next?" and use it
 622         to decide whether the regexp/noteol flag should be added.
 623
 624         1999-02-26  Gary Houston  <ghouston@easynet.co.uk>
 625
 626         * boot-9.scm (top-repl): don't flush all ports at exit.
 627         (error-catching-loop): likewise.
 628
 629         1998-12-23  Gary Houston  <ghouston@easynet.co.uk>
 630
 631         * boot-9.scm (scm-style-repl): -read: don't call
 632         consume-trailing-whitespace if val is eof object.  Allows
 633         exiting repl with single control-D.
 634
 635         1998-12-06  Gary Houston  <ghouston@easynet.co.uk>
 636
 637         * boot-9.scm (error-catching-loop): don't force output within
 638         error catching loop after quit received.
 639         (top-repl): flush all ports when the repl terminates.
 640
 641         * boot-9.scm (error-catching-loop): flush all ports before
 642         primitive exit if non-interactive.
 643         force-output on current-error-port if interactive.
 644
 645         * boot-9.scm (reopen-file): deleted.
 646         * popen.scm (open-output-pipe, open-input-pipe): moved from
 647         boot-9.scm.
 648         * popen.scm: new file.
 649
 650 1999-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 651
 652        * boot-9.scm (iota):  replaced by a tail recursive version.
 653        (reverse-iota):  removed.
 654
 655 1999-06-03  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 656
 657         * optargs.scm (lambda*): Bugfix: Replaced ARGLIST -->
 658         non-optional-args.  (Thanks to David Lutterkort.)
 659
 660 1999-05-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 661
 662         * string-case.scm: Removed; functions moved to libguile/strop.c
 663         (which could be dynamically linked in the future anyway).
 664         * Makefile.am (ice9_sources): Don't list string-case.scm.
 665         * Makefile.in: Regenerated.
 666         * format.scm: Don't bother importing (ice-9 string-case).
 667
 668 1999-05-02  Jim Blandy  <jimb@savonarola.red-bean.com>
 669
 670         * boot-9.scm (provided?): New function.
 671
 672         * Makefile.am: Add string-case.scm and format.scm to ice9_sources.
 673         * Makefile.in: Regenerated.
 674
 675         * string-case.scm: New file, brought in from SLIB, and adapted to
 676         Guile's module system.
 677
 678         * format.scm: New file, brought in from SLIB, with the following
 679         changes:
 680         (format:format): If the first argument is the format string, stick
 681         a #f on the front of it, so it is now a valid CL format argument
 682         list.  This is easier than changing everyplace else (like the
 683         error formatter) that expects it to be in CL form.  The other
 684         clause which explicitly tests for this case is now dead code.
 685         (format:format-work): Allow `@' and `:' in either order, as per
 686         modern CL behavior.
 687         (format:num->cardinal): Don't assume that an elseless if returns
 688         '() when the condition is false.
 689
 690 1999-04-17  Jim Blandy  <jimb@savonarola.red-bean.com>
 691
 692         * Makefile.in: Regenerated.
 693
 694 1999-04-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 695
 696         * boot-9.scm: Provide 'values.
 697
 698 1999-03-21  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 699
 700         * boot-9.scm (process-define-module, use-syntax): Bugfix:
 701         :use-syntax should add syntax to using module, not current module.
 702         (internal-use-syntax): Removed.
 703
 704 1999-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 705
 706         * session.scm (apropos-internal): Modified to comply with new
 707         argument order for hash-fold.
 708
 709 1999-03-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 710
 711         * boot-9.scm (try-load-module): New procedure.  Broken out from
 712         resolve-module.
 713         (resolve-module): Bugfix: Make it possible for a module at a
 714         deeper level (x y z) to depend on a module on a higher (x y).
 715
 716         This also has the desired side-effect that multiple attempts to
 717         load a module (e.g. with `use-modules') work until source is
 718         actually found for the module (e.g. because the correct catalog
 719         has been added to the load path).
 720
 721         Use try-load-module.
 722
 723 1999-03-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 724
 725         * session.scm (system-module): New procedure.  Used to switch a
 726         module between system and user state.
 727
 728 1999-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 729
 730         * session.scm (apropos-internal): Rewritten using hash-fold.
 731
 732         * emacs.scm, session.scm, slib.scm): Added :no-backtrace in module
 733         definition.
 734
 735 1999-03-14  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 736
 737         * boot-9.scm (make-record-type): Use `set-struct-vtable-name!' to
 738         associate a name to the record type descriptor so that the object
 739         system can create a wrapper class for it.
 740
 741 1999-03-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 742
 743         Improvement of backtraces: Introduces a new stack narrowing
 744         specifier, #t, for the inner cut.  If the inner cut is specified
 745         by #t, `make-stack' will throw away inner stack frames (most
 746         recent calls on call chain) up to but excluding the first user
 747         stack frame encountered.

 749         This specifier is now used in `save-stack' so that the call
 750         `(save-stack)' will get the new behaviour. [It is recommended that
 751         any error reporting functions written by the user have this call
 752         on the outermost expression level (i.e. as a member of the lambda
 753         list).]
 754
 755         Modules are partitioned into "user" and "system" modules. [I know
 756         that some names used here are silly, but I don't have more time to
 757         spend on a better solution, especially considering that the module
 758         system will be replaced.  But if people have better ideas, then
 759         please tell me!]
 760
 761         System modules are created by adding :no-backtrace among the
 762         define-module switches:
 763
 764         (define-module (foo)
 765           :no-backtrace)
 766
 767         Modules which doesn't have the :no-backtrace specifier are user
 768         modules.
 769
 770         A stack frame is classified as a user frame if it has source code
 771         associated with it and if this source code can be proven to come
 772         from a user module.  If it can be proven to come from a system
 773         module it is a system frame.
 774
 775         Frames which can't be classified, e.g. application frames, are cut
 776         away if they occur between system frames, but are left on the
 777         stack if they occur between the last system frame and the first
 778         user frame encountered.  (Note that the first user frame
 779         encountered is the last user code being evaluated!)
 780
 781         In some cases the system part of the call chain is introduced by
 782         frames which should but can't be proven to be system frames.  The
 783         following workaround has been implemented: The cutting proceeds
 784         over application frames where the operator is marked by the
 785         `system-procedure' property.  (This has been used to cut away
 786         generic function dispatch code in the object system.)
 787
 788         * boot-9.scm (set-system-module!): New procedure: Set system/user
 789         status of a module.;
 790         Mark `the-root-module' and `the-scm-module' as system modules.
 791         (process-define-module): Add new keyword :no-backtrace.
 792
 793         * boot-9.scm (environment-module): Bugfixed.
 794         (set-module-eval-closure!): Add a pointer back from the eval
 795         closure to the module.
 796
 797         * emacs.scm (emacs-load): Reset port filename after transfer.
 798

 802
 803 1999-02-16  Maciej Stachowiak  <mstachow@alum.mit.edu>
 804
 805         * optargs.scm (lambda*): Handle empty argument lists properly.
 806
 807 1999-02-15  Jim Blandy  <jimb@savonarola.red-bean.com>
 808
 809         Fix from Russ McManus:
 810         * getopt-long.scm (parse-option-spec): Store 'optional as the
 811         value-required? field for options that take optional values.
 812         (process-short-option): Grab a value for the option when it takes
 813         either an optional or required value.
 814
 815 1999-02-12  Jim Blandy  <jimb@savonarola.red-bean.com>
 816
 817         * getopt-long.scm: Remove debugging calls to `pk'.
 818
 819         * getopt-long.scm: Return list of ordinary arguments as the value
 820         of the '() key, not `rest'.
 821
 822         A new argument-processing package from Russ McManus.
 823         * getopt-long.scm: New file.
 824         * Makefile.am (ice9_sources): Added getopt-long.scm.
 825         * Makefile.in: Regenerated.
 826
 827 1999-02-09  Maciej Stachowiak  <mstachow@alum.mit.edu>
 828
 829         * optargs.scm: New file.
 830         * Makefile.am (ice9_sources): Add optargs.scm here. Makefile.in
 831         not regenerated because I don't have the right version of Automake.
 832
 833 1999-02-06  Jim Blandy  <jimb@zwingli.cygnus.com>
 834
 835         * and-let*.scm: New file, from Michael Livshin.
 836         * Makefile.am (ice9_sources): Add and-let* here.
 837         * Makefile.in: Regenerated.
 838
 839 1999-01-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 840
 841         * slib.scm (install-require-module): Fixed the kludge which loads
 842         the slib catalog: Doesn't anylonger assume that the feature tested
 843         for isn't loaded.
 844
 845 1998-12-14  Jim Blandy  <jimb@zwingli.cygnus.com>
 846
 847         * Makefile.in: Regenerated.
 848
 849 1998-12-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 850
 851         * boot-9.scm (process-define-module): Reverted the change of
 852         1998-11-23 which caused loading of object code if :use-module was
 853         applied to the module itself.
 854
 855 1998-12-11  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 856
 857         * Makefile.am: Removed setf.scm.
 858
 859         * setf.scm: Removed.  1. It was buggy.  2. It was unschemey.
 860         (These shortcomings were my fault.)
 861
 862 1998-12-10  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 863
 864         * boot-9.scm (environment-module): New procedure.
 865
 866 1998-12-07  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 867
 868         * Makefile.am: Added setf.scm.
 869
 870 1998-12-05  Christian Lynbech  <chl@tbit.dk>
 871
 872         * setf.scm: New file.  Adds the new forms `setf!' and `setter'
 873         which implements generalized references a la Common LISP.
 874
 875 1998-12-02  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 876
 877         * boot-9.scm (process-define-module): Added new specifier
 878         :autoload MODULENAME BINDINGS to the define-module form.
 879         The autoload specifier tells the module system to load the module
 880         MODULENAME at the first occasion that any variable with its name
 881         among BINDINGS is referenced.
 882         (make-autoload-interface): New procedure:  Constructs a stand-in
 883         for the public interface for the module to be autoloaded.
 884
 885 1998-12-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 886
 887         * boot-9.scm (*suppress-old-style-hook-warning*): Set this to #t
 888         if you don't want the old style hook warnings.
 889
 890 1998-12-01  Christian Lynbech  <chl@tbit.dk>
 891
 892         * boot-9.scm (try-using-libtool-name): Fix check on dlname to make
 893         sure that it isn't empty, as it is when we are only buidling
 894         static libraries.
 895
 896 1998-11-27  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 897
 898         * session.scm (arity): New procedure.
 899
 900 1998-11-26  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 901
 902         * boot-9.scm: Use run-hook instead of run-hooks everywhere.
 903
 904 1998-11-26  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 905
 906         * boot-9.scm (run-hooks, add-hook!, remove-hook!): Added temporary
 907         code for backward compatibility until people have had time to
 908         adapt to the new hooks.
 909
 910 1998-11-23  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 911
 912         * boot-9.scm (beautify-user-module!): Beautify also if public
 913         interface is set to the module itself.  In this way we can use
 914         beautify-user-module! to beautify a module prepared for object
 915         code.
 916         (process-define-module): Special case: Try to load object code as
 917         well if a module does :use-module on itself.
 918
 919         * boot-9.scm: Bugfix: Since boot-9.scm is now loaded from
 920         invoke_main_func, we can no longer be sure that all modules have
 921         been registered when boot-9.scm is loaded.
 922         (register-modules): New function: Register and tag modules
 923         registered by scm_register_module_xxx since last call to this
 924         function.  Modules are tagged with the dynamic object passed as
 925         argument.  (Already linked modules should be tagged with #f.)
 926         (init-dynamic-module, link-dynamic-module): Call register-modules
 927         first to register linked modules.
 928
 929         * boot-9.scm (init-dynamic-module): Remove module from
 930         registered-modules as soon as possible in case we are recursively
 931         invoked; Set public interface before doing the dynamic-call.
 932
 933         * boot-9.scm (map-in-order): Removed (replaced by scm_serial_map).
 934         (abort-hook, before-error-hook, after-error-hook,
 935         before-backtrace-hook, after-backtrace-hook, before-read-hook,
 936         after-read-hook, exit-hook): Make hooks with `make-hook'.
 937
 938         * boot-9.scm: Make hooks first class citizens and make them easier
 939         to use from C:
 940         (make-hook, add-hook!, remove-hook!, run-hooks): Moved to
 941         libguile/feature.c.
 942
 943         * boot-9.scm: Added warnings about bindings used in
 944         libguile/modules.c: the-module, set-current-module,
 945         make-modules-in, beautify-user-module!, module-eval-closure.
 946
 947 1998-11-21  Mikael Djurfeldt  <mdj@kenneth>
 948
 949         * boot-9.scm (the-environment): New special form: Returns an
 950         object representing the current local evaluation environment.
 951         This object can be used in `local-eval' and `defined?'.
 952
 953 1998-11-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 954
 955         * boot-9.scm (collect): New syntax.  Similar to begin but returns
 956         a list of the results of all forms in the sequence instead of the
 957         result of the last form.
 958
 959 1998-11-10  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 960
 961         * boot-9.scm (values, call-with-values): Moved here from
 962         syncase.scm.
 963
 964         * syncase.scm (values, call-with-values): Moved to boot-9.scm.
 965
 966         * boot-9.scm (readline-options, readline-enable, readline.disable,
 967         readline-set!: New options interface.
 968
 969         * readline.scm (readline-port): Use readline-options-interface.
 970
 971 1998-11-05  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 972
 973         * boot-9.scm: Set the repl start module in `top-repl' instead of
 974         at the end of boot-9.scm.
 975
 976 1998-11-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 977
 978         * emacs.scm (format): Bugfix: Handle multiple arguments
 979         correctly.  (Thanks to Thien-Thi Nguyen.)
 980
 981 1998-11-01  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 982
 983         * boot-9.scm (exit-hook): New hook: Is run at the very end of an
 984         interactive session.
 985         (top-repl): Run exit-hook on exit.
 986
 987         * readline.scm (readline-port): Maybe read history; Maybe write
 988         history at exit (add to exit-hook).
 989
 990 Fri Oct 30 15:15:37 1998  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 991
 992         * readline.scm (make-readline-port): Bugfixed last change...
 993
 994 1998-10-28  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 995
 996         * readline.scm (make-readline-port): Don't set prompt to "... " if
 997         read line was empty.
 998
 999 1998-10-19  Jim Blandy  <jimb@zwingli.cygnus.com>
1000
1001         * boot-9.scm, debug.scm, expect.scm, hcons.scm, lineio.scm,
1002         r4rs.scm, slib.scm, threads.scm: Update copyright years.
1003
1004         * getopt-gnu-style.scm, slib.scm: Add copyright notice.
1005
1006         Talked to Stallman.  Actually, the syntax-case copyright is no
1007         problem.  Duh.
1008         * Makefile.am (ice9_sources): Revert last change.
1009         * syncase.scm, psyntax.pp, psyntax.ss: Added again.
1010         * Makefile.in: Regeneretade.
1011
1012         * boot-9.scm: Don't assume that this file is loaded just before
1013         entering a read-eval-print loop.  Turn code to load (ice-9 emacs)
1014         into...
1015         (load-emacs-interface): New function.
1016         (top-repl): Call it, if use-emacs-interface is defined and true.
1017         At this point, we *do* know we're about to enter a REPL.
1018
1019         We can't include Kent Dybvig's syntax-case macro expander in the
1020         core Guile distribution, because we don't have copyright
1021         assignments for this code.  We can certainly distribute them as a
1022         separate package, but Guile should be FSF code.
1023         * syncase.scm, psyntax.pp, psyntax.ss: Removed.
1024         * Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
1025         psyntax.ss.
1026         * Makefile.in: Regenerated.
1027
1028         * Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
1029         * Makefile.in: Regenerated.
1030
1031 1998-10-18  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1032
1033         * boot-9.scm: Added extended read syntax for byte vectors #y(...)
1034         and short vectors #h(...).
1035
1036 1998-10-14  Jim Blandy  <jimb@zwingli.cygnus.com>
1037
1038         * calling.scm (excursion-function-syntax): Use a sequence of
1039         set!'s, not a single multi-variable set!; we removed support for
1040         that syntax a long time ago.  (Thanks to Shuji Narazaki.)
1041
1042 1998-10-12  Jim Blandy  <jimb@zwingli.cygnus.com>
1043
1044         * r4rs.scm (OPEN_READ, OPEN_WRITE, OPEN_BOTH): Don't bother
1045         testing software-type here.  That's the least of our Windows
1046         porting issues, and it's done wrong anyway.
1047
1048 1998-10-09  Jim Blandy  <jimb@zwingli.cygnus.com>
1049
1050         * boot-9.scm (read-path-list-notation-warning): New function:
1051         print a warning the first time we see `#/' notation.
1052
1053         * q.scm (sync-q!, q?, q-remove!, q-push!, enq!): Lots of bugs, and
1054         (eq?  #f '()) assumptions.  Make functions that aren't documented
1055         to return anything else return the queue itself.  (Bug report from
1056         Michael Livshin --- thanks!)
1057
1058 1998-08-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1059
1060         * debug.scm (trace-entry, trace-exit): Removed re-enabling of
1061         trace flag.
1062
1063         * boot-9.scm (make-options): Bugfix: Changed pair? --> list? in
1064         order to allow the empty list as arg.
1065         (error-catching-loop): Use `with-traps' to create a dynamic
1066         context with traps enabled.
1067
1068 1998-08-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1069
1070         * boot-9.scm: Removed (ice-9 regex) from use-list of (guile)
1071         module.
1072         (try-using-libtool-name): Removed dependency on (ice-9 regex).
1073
1074 1998-08-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1075
1076         * boot-9.scm: Make the root module use (ice-9 regex) if
1077         available.  The dynamic linking facilities in boot-9.scm are
1078         currently dependent upon regular expressions.  My change of
1079         1998-07-14 removed (ice-9 regex) from the use-list of the root
1080         module and thereby destroyed dynamic linking.
1081
1082 1998-07-29  Jim Blandy  <jimb@zwingli.cygnus.com>
1083
1084         * Makefile.in: Regenerated using the last public version of
1085         automake, not the hacked Cygnus version.
1086
1087 1998-07-28  Jim Blandy  <jimb@zwingli.cygnus.com>
1088
1089         * Makefile.in: Regenerated, after removing Totoro kludge.
1090
1091 1998-07-28  Jim Blandy  <jimb@totoro.red-bean.com>
1092
1093         * getopt-gnu-style.scm: New file.  (Thanks to Russ McManus.)
1094
1095 1998-07-26  Jim Blandy  <jimb@zwingli.cygnus.com>
1096
1097         * Makefile.in Rebuilt, for config changes in parent dir.
1098
1099 1998-07-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1100
1101         * readline.scm (make-readline-port): Set prompt string to "... "
1102         after first read line.  (Thanks to Richard Polton.)
1103
1104 1998-07-19  Jim Blandy  <jimb@zwingli.cygnus.com>
1105
1106         * lineio.scm (make-line-buffering-input-port): Don't use
1107         ungetc-char-ready?, since we don't provide that function any
1108         more.  The unread-string function doesn't interact properly with
1109         any of the standard I/O functions anyway.  (Thanks to Andrew
1110         Archibald.)
1111
1112         * hcons.scm (hashq-cons-assoc): Don't assume the empty list is
1113         false.  Return false when we cannot find a matching entry in the
1114         list.  (Thanks to Andrew Archibald.)

1117
1118         * boot-9.scm (export, export-syntax): New special forms: Export
1119         bindings from a module.  `(export name1 name2 ...)' can be used at
1120         the top of a module (after `define-module') to specify which names
1121         should be exported.  It can be used as an alternative to
1122         `define-public'.  `export-syntax' works equivalently to `export'
1123         but is intended for export of syntactic keywords.
1124         (Thanks to Thien-Thi Nguyen.)
1125
1126 1998-07-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1127
1128         * boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.
1129
1130 1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1131
1132         * boot-9.scm: Let the user start in module `(guile-repl)' instead
1133         of module `(guile)'.  Also make sure that `(guile-repl)' uses
1134         suitable modules.  This change improves Guile stability
1135         substantially since bindings will only be copied from the root
1136         module: If the user redefines builtins in `(guile-repl)' it won't
1137         affect the internal operation of Guile itself.
1138
1139 1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1140
1141         * boot-9.scm (load-module): When loading files from within files
1142         themselves being loaded: Use the directory path of the file being
1143         loaded as root for relative filenames.  (After suggestion by
1144         Steven G. Johnson.)
1145
1146 1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1147
1148         * emacs.scm (emacs-load): New feature: Eval in specified module.
1149
1150 1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1151
1152         * readline.scm: Typo in regex module name.
1153
1154 1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1155
1156         * readline.scm (apropos-completion-function): regexp-quote text to
1157         be completed.
1158
1159 1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1160
1161         * debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.
1162
1163 1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1164
1165         * boot-9.scm: Check that (current-input-port) is a tty before
1166         enabling readline.  (Thanks to Michael N. Livshin.)
1167
1168 1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1169
1170         * boot-9.scm (use-syntax): Turned into a macro inorder to be
1171         similar in use to `use-modules'.
1172         Example: (use-syntax (ice-9 syncase)) will 1. load the module
1173         (ice-9 syncase), and, 2. install the procedure `syncase' as eval
1174         transformer.
1175         (internal-use-syntax): New procedure.
1176         (process-define-module): Use `internal-use-syntax'.
1177
1178 1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1179
1180         * Makefile.am (ice9_sources): Add emacs.scm.
1181
1182 1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1183
1184         * readline.scm: Use the new readline facilities: Add the
1185         possibility to control input and output ports; Add apropos
1186         completion.
1187
1188         * boot-9.scm: Antirevert Jim's readline code which he reverted
1189         19971027 and adapt it to the current readline interface.
1190
1191         * boot-9.scm (top-repl): Only enable readline if not using the
1192         Emacs interface; Only use repl prompt when using the readline port
1193         from repl-read.  (We don't want to see it when calling `read'.)
1194
1195         * boot-9.scm (remove-hook!): Parenthesis bug.
1196
1197 1998-05-11  Mikael Djurfeldt  <mdj@kenneth>
1198
1199         * boot-9.scm: Load readline module if readline is present.
1200
1201         * readline.scm (apropos-completion-function): New procedure:
1202         Symbolic completion.  (Thanks to Andrew Archibald!)
1203
1204 1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1205
1206         * boot-9.scm (process-define-module): Added keyword use-syntax.
1207
1208 1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1209
1210         * nonblocking.scm: Removed.  libguile is now inherently
1211         nonblocking through the use of scm_internal_select.
1212
1213         * emacs.scm: Removed use of nonblocking.scm.
1214
1215         * gwish.scm, gtcl.scm: Removed.  tcltk.scm has made these
1216         obsolete.
1217
1218 1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>
1219
1220         * runq.scm (runq-control): Corrected spelling of enqueue!.
1221         (Thanks to Karl M. Hegbloom.)
1222
1223 1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>
1224
1225         * boot-9.scm: Added new run-time option interface eval-options.
1226
1227 1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1228
1229         * boot-9.scm (remove-hook!): New macro.  (Thanks to Maciej
1230         Stachowiak.)
1231
1232 1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1233
1234         * threads.scm: Added simple error and signal handler.
1235         (make-thread, begin-handler): Use this handler.  The most
1236         important effect of this is that signals get unmasked.
1237         Previously, when a signal was thrown signals remained masked
1238         (signals get masked when a signal is taken) which influenced other
1239         threads.
1240
1241 1998-01-01  Tim Pierce  <twp@skepsis.com>
1242
1243         A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
1244         * slib.scm (identity): Unmake public.
1245         (slib:eval): Evaluate inside `slib-module'.
1246
1247 1997-12-24  Tim Pierce  <twp@skepsis.com>
1248
1249         * boot-9.scm: Doc fix.
1250
1251         * slib.scm (identity): Made public.
1252         (home-vicinity): New function (from SLIB/Template.scm).
1253
1254 1997-12-13  Tim Pierce  <twp@skepsis.com>
1255
1256         * boot-9.scm (read-line): Rewritten to call %read-line for
1257         improved speed.  Minor user-visible changes: the new functions are
1258         hardwired to treat the LFD character as signifying end-of-line, so
1259         changing `scm-line-incrementors' will no longer affect the
1260         behavior of read-line.  On platforms which do not represent
1261         end-of-line with a LFD character, read-line should behave more
1262         like native line-processing facilities, but there is still a ways
1263         to go here.
1264
1265 Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>
1266
1267         * boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
1268         is now a fluid.
1269
1270 1997-11-28  Tim Pierce  <twp@skepsis.com>
1271
1272         * boot-9.scm (find-and-link-dynamic-module): If a module directory
1273         contains a .la file (a libtool support file), attempt to extract
1274         the shared library name from that file.  If the .la file does not
1275         exist, try to link against a .so file.  Libtool-generated compiled
1276         modules should load more cleanly in Guile now.
1277         (try-using-libtool-name, try-using-sharlib-name): New functions.
1278
1279 Sun Nov  9 06:10:59 1997  Gary Houston  <ghouston@actrix.gen.nz>
1280
1281         * boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
1282         usefully so they will work from a script.
1283
1284 1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>
1285
1286         * boot-9.scm (inherit-print-state): Moved definition to the
1287         neighborhood of the record code.
1288
1289 Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1290
1291         * boot-9.scm: Revert changes to this file from Oct 23.  It turns
1292         out to interact badly with the Emacs support and the Tcl/Tk
1293         support.  It's not a high enough priority at the moment to be
1294         worth fixing.  I'm leaving the other readline support in, though.
1295
1296 Sat Oct 25 14:23:22 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1297
1298         * Makefile.am: Include readline.scm in the list of files to be
1299         installed, so Guile can find it for interactive use.
1300         * Makefile.in: Regenerated.
1301
1302 Thu Oct 23 01:00:33 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1303
1304         Add support for readline function.
1305         * readline.scm: New module.
1306         * boot-9.scm (repl-reader): New function.
1307         (scm-style-repl): Call repl-reader, instead of doing the reading
1308         ourselves.  Remove repl-report-reset; it was never used for
1309         anything.
1310         (top-repl): If we've got the readline primitives, then redefine
1311         repl-reader to use them.
1312         If we've got the readline primitives, import the readline module.
1313
1314         * ls.scm (ls, lls): Don't assume (eq? #f '()).
1315
1316 Wed Oct 22 18:26:57 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1317
1318         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1319         string-fun.scm: Added copyright notices; reformatted.
1320
1321 Thu Oct  9 05:44:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1322
1323         * expect.scm: (expect-regexec): new procedure, use it in
1324         expect-strings to fix the => syntax under the new regex system.
1325         (top): include regex module in define-module statement.
1326
1327 Wed Oct  8 03:16:01 1997  Gary Houston  <ghouston@actrix.gen.nz>
1328
1329         * (error-catching-loop): new local variable "interactive".  if
1330         #f, abort terminates the process.
1331         (set-batch-mode?!, batch-mode?): new closures, defined in
1332         error-catching-loop.  the names are from scsh.
1333
1334 1997-10-06  Marius Vollmer  <mvo@zagadka.ping.de>
1335
1336         * boot-9.scm (inherit-print-state): If NEW-PORT contains a
1337         print-state, throw it away.
1338
1339 Fri Oct  3 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
1340
1341         * boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
1342         `0'.
1343
1344 Thu Oct  2 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
1345
1346         * boot-9.scm (struct-printer, make-struct-printer,
1347         set-struct-printer-in-vtable!, *struct-printer*): Removed.
1348         (record-type-vtable, make-record-type): Don't use make-struct-printer.
1349         (record-type-vtable): User fields "prpr" (printer is no longer a
1350         user field).
1351         (record-type-name, record-type-fields): Decreased slot index by
1352         one; Use `vtable-offset-user'.
1353
1354 Thu Oct  2 12:00:00  Marius Vollmer  <mvo@zagadka.ping.de>
1355
1356         * boot-9.scm (inherit-print-state): New experimental function.
1357
1358 Tue Sep 30 13:12:48 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1359
1360         Suggestion and script from Maciej Stachowiak:
1361         * boot-9.scm: Split off modules into separate, autoloadable files.
1362         This reduces startup time from 10.5s to 5.5s (user cpu).
1363         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1364         string-fun.scm: New files, containing stuff that used to be in
1365         boot-9.scm.
1366         * Makefile.am (ice9_sources): List new files here, for
1367         distribution and installation.
1368         * Makefile.in: Regenerated.
1369
1370 Mon Sep 29 23:53:55 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1371
1372         * Makefile.in: Regenerated with automake 1.2c.
1373
1374 Mon Sep 29 03:21:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1375
1376         * slib.scm (slib:load): slib:load first tries to load the file
1377         named NAME, then NAME.scm.  On error, report the error occuring at
1378         the first attempt (NAME) rather than the second (NAME.scm).
1379
1380         * boot-9.scm: Bugfix: Hard-solder the print-option procedure into
1381         the make-options macro so that we needn't refer to a global
1382         symbol.
1383
1384 Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1385
1386         * debug.scm: Moved options interface procedures to boot-9.scm.
1387
1388         * boot-9.scm: Define options interface procedures here instead.
1389
1390 Sat Sep 27 20:19:20 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1391
1392         * boot-9.scm (separate-fields-discarding-char,
1393         separate-fields-after-char, separate-fields-before-char): Call
1394         continuation function, RET, as advertised: with each separated
1395         field a separate argument.
1396
1397         * Makefile.in: Regenerated with automake 1.2a.
1398
1399 Sat Sep 20 14:23:53 1997  Mikael Djurfeldt  <mdj@kenneth>
1400
1401         * slib.scm (slib:load): Export.
1402
1403         * boot-9.scm (in-vicinity): Bugfix: Don't add "/" to an empty
1404         vicinity;
1405         Provide defmacro.
1406
1407 Thu Sep 18 01:24:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1408
1409         * r4rs.scm (apply): Set name property to 'apply.
1410
1411 Tue Sep 16 22:09:50 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1412
1413         * boot-9.scm (keyword->symbol, display-usage-report): Changed
1414         length --> string-length.  (Thanks to Aleksandar Bakic.)
1415         (separate-fields-discarding-char, separate-fields-after-char,
1416         separate-fields-before-char): Bugfix from Maciej Stachowiak
1417         <mstachow@mit.edu>.  Thanks!
1418         (try-module-linked): Try to find module among those already
1419         registered.
1420         (try-module-dynamic-link): Removed the first test which
1421         corresponds to a call to `try-module-linked'.
1422         (resolve-module): Resolve modules in this order: 1. Already
1423         registered modules (for example those which have been statically
1424         linked), 2. Try to autoload an .scm-file, 3. Try to dynamically
1425         link a .so-file.
1426
1427 Mon Sep 15 23:39:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1428
1429         * boot-9.scm (iota): Renamed list-reverse! --> reverse!
1430
1431 Thu Sep 11 02:31:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1432
1433         * session.scm (name): New procedure: Gives name of object.
1434         (source): New procedure: Gives source of object.
1435
1436 Wed Sep 10 20:12:45 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1437
1438         * boot-9.scm (primitive-macro?): New procedure.
1439
1440         * slib.scm: Added hack which transfers syntactic information from
1441         the builtin variable `define' to the slib version if module (ice-9
1442         syncase) has been loaded.  This is necessary to get correct
1443         expansion inside the slib module.
1444
1445         * psyntax.ss (build-let, build-named-let): New output
1446         constructors.
1447         (build-lexical-var): Seed gensym with symbolic name.
1448         (self-evaluating?): Add keywords among self-evaluating types.
1449         (let): New core form.
1450         (if): Removed from core language.
1451         (or, and, let, cond): Removed syntactic definitions.
1452         (sc-expand3): New procedure: Expander which takes optional mode
1453         and eval-syntactic-expanders-when arguments.
1454
1455         * syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
1456         Should be used inside the (ice-9 syncase) module with (use-syntax
1457         syncase) and with the current directory containing the psyntax.ss
1458         source.
1459         Added hack to transfer syntactic information from the builtin
1460         variable `define' to the slib version if module (ice-9 slib) has
1461         been loaded.

1465         * syncase.scm (sc-interface, sc-expand): Removed hook setup.
1466         (syncase): Publish syntax transformer to be used with
1467         `use-syntax'.
1468         (sc-macro): Use this as the value when publishing macros.
1469
1470         * boot-9.scm (module-type): Added `transformer'.
1471         (make-module): Modified initialization.
1472         (module-transformer, set-module-transformer!): Selector and
1473         mutator for module-associated transformer.
1474         (set-current-module): Use module-transformer to set
1475         `scm:eval-transformer'.
1476         (module-use!): Previous change reverted.
1477         (use-syntax): New function: Install a transformer in current
1478         module.
1479         (sc-interface, sc-expand): Removed! :)
1480
1481 Fri Sep  5 03:09:09 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1482
1483         * emacs.scm (emacs-load): Added new parameter `module'.
1484
1485         * syncase.scm (putprop, getprop): Modified to use the object
1486         properties of the variable object corresponding to the symbol;
1487         This way we can ride on the mechanisms of the module system.
1488         Changed `builtin-variable' calls to `define-public' calls.
1489         Setup the hooks sc-expand and sc-interface.
1490

1492         (set-current-module): Switch to and from sc-expand as
1493         scm:eval-transformer when going into and out of modules using
1494         syncase macros.
1495         (module-use!): Set scm:eval-transformer to sc-expand when adding
1496         the syncase interface.
1497
1498 Thu Sep  4 14:57:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1499
1500         * syncase.scm (putprop): Temporary fix which publishes new syntax
1501         globally (the old behaviour was complex and connected to the inner
1502         workings of the current module system).
1503
1504 Wed Sep  3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1505
1506         * psyntax.ss: Updated.
1507         psyntax.pp: Bugfix: Previous version had some leading "t":s cut
1508         off!
1509
1510 Tue Sep  2 00:26:42 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1511
1512         * boot-9.scm (gensym): Removed (replaced by primitive).
1513         (obarray-gensym): Rewritten to use `gensym'.
1514         (gentemp): Rewritten to use `gensym'.
1515
1516 Mon Sep  1 20:08:32 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1517
1518         * gtcl.scm (make-tcl-binder): Rewritten to choose bindings
1519         according to the following priorities:
1520         1. tcl bindings which are present in override-scheme-list
1521         2. bindings from the-scm-module
1522         3. tcl bindings
1523         This way the gtcl module can occur first in the use-list without
1524         disabling the scheme interpreter.
1525         (new-interpreter): New function.
1526
1527         * gwish.scm: Moved initialization code for the-interpreter to
1528         gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
1529         it; Call `new-interpreter'; Don't :use-module (guile).
1530
1531 Thu Aug 28 23:48:53 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1532

1534
1535 Wed Aug 27 11:35:09 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1536
1537         * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1538
1539 Mon Aug 25 22:00:44 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1540
1541         * emacs.scm (object->string, format, error-args->string): New
1542         procedures.
1543         (emacs-frame-eval): Reworked.
1544
1545 Mon Aug 25 16:15:55 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1546
1547         * session.scm (apropos-internal): Musn't initialize symbol
1548         accumulator with a constant pair.  That led to mutation of the
1549         source!
1550
1551 Sun Aug 24 01:03:10 1997  Mikael Djurfeldt  <mdj@kenneth>
1552
1553         * session.scm (vector-for-each): Removed.
1554         (apropos): vector-for-each --> array-for-each.
1555         (apropos-internal): New function.  Return list of accessible
1556         symbols matching regexp.
1557
1558         * debug.scm (frame-number->index): New function.  Convert frame
1559         number (as displayed in the backtrace) to frame index (to be used
1560         in stack-ref).
1561
1562         * emacs.scm (emacs-load): New arguments: interactivep: when
1563         non-false, send back results to Emacs; colnum: Column number;
1564         Use modules (ice-9 debug) and (ice-9 session);
1565         (no-stack, no-source): New simple-actions;
1566         (result-to-emacs): New procedure. Sends data to Emacs via the
1567         result protocol;
1568         (get-frame-source, emacs-select-frame, emacs-frame-eval,
1569         emacs-symdoc): New procedures.
1570
1571 Wed Aug 20 13:21:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

1577         procedure names during loading of psyntax.pp.
1578
1579         * psyntax.pp: Removed leading blanks => 800K -> 100K.
1580
1581 Tue Aug 19 02:39:41 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1582
1583         * syncase.scm: Don't tamper with debug mode setting when enabling
1584         macros.  Instead cut the stack with start-stack.
1585         Load psyntax.pp with recording of positions turned off.
1586
1587         * psyntax.pp, psyntax.ss (quasiquote): Changed fx= --> =.
1588
1589         * syncase.scm: New file: Guile-adaption for syntax-case macros.
1590         * psyntax.pp, psyntax.ss: Syntax-case macros, portable version 2 by
1591         R. Kent Dybvig, Oscar Waddell, Bob Hieb and Carl Bruggeman
1592
1593 Mon Aug 18 21:58:25 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1594
1595         * session.scm: New file: Session support.
1596         (apropos): New procedure: List bindings given regexp.
1597
1598 Sat Aug 16 18:44:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
1599
1600         * boot-9.scm: define tms accessors: clock, utime, stime, cutime,
1601         cstime.
1602
1603 Thu Aug 14 19:55:37 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1604
1605         * emacs.scm (emacs-load): Something has changed in the reader so
1606         that we now should set the port line count to the specified value
1607         (linum) instead of (- linum 1).
1608
1609         * slib.scm (slib:load): Use load-from-path instead of
1610         primitive-load-path so that backtraces get narrowed properly at
1611         the top.
1612
1613         * boot-9.scm (top-repl): Save stack already in signal handler in
1614         order to narrow it correctly.
1615         (save-stack): Adjust narrowing tag for the top of load-stacks.
1616
1617 Tue Jul 29 01:18:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
1618
1619         * boot-9.scm (move->fdes, dup->port): use dup->fdes, not primitive-dup.
1620         (dup->fdes): deleted, now done in C.
1621
1622 Sat Jul 26 08:00:42 1997  Gary Houston  <ghouston@actrix.gen.nz>
1623
1624         * boot-9.scm (setenv): new procedure, scsh compatible.
1625
1626 Sat Jul 26 21:30:10 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1627
1628         * boot-9.scm (with-fluids): New macro to go with the
1629         builtin `with-fluids*'.
1630
1631 Thu Jul 24 04:28:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1632
1633         * slib.scm (install-require-module): In newer versions of slib
1634         *catalog* is #f until the first access.  Therefore we call
1635         require:provided? for a random feature if *catalog* is #f.
1636
1637 Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1638
1639         * boot-9.scm: If using emacs interface, enable backtraces
1640         automatically.
1641
1642 Mon Jul 21 06:45:45 1997  Gary Houston  <ghouston@actrix.gen.nz>
1643
1644         * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
1645         dup, fdes->inport, fdes->outport, port->fdes): new procedures.
1646         (duplicate-port): was a C primitive, now it's here.
1647         (move->fdes): allow the first argument to be a file descriptor.
1648         Return the modified port or file descriptor (was unspecified.)
1649
1650 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
1651
1652         Changes to compile under gnu-win32, from Marcus Daniels:
1653         * boot-9.scm (load-user-init): If HOME is unset, provide
1654         a default of /.
1655
1656         * boot-9.scm (define-public): Changed to accomodate Hobbit.
1657
1658 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
1659
1660         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
1661         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
1662         notation, instead of #/ notation.
1663
1664         * expect.scm (expect-strings): Pass regexp/newline flag to
1665         make-regexp.
1666
1667 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
1668
1669         Fix inconsistencies in parsing of #/ style lists.
1670         * boot-9.scm (read-path-list-notation): New function.
1671         (parse-path-symbol): Deleted.  Replaced by above.
1672         Plug in read-path-list-notation as the parser for #/ lists,
1673         instead of the anonymous lambda form calling parse-path-symbol.
1674         (Thanks to Maurizio Vitale.)
1675
1676         * boot-9.scm (make-list): Remove the definition of this function
1677         from the (ice-9 common-list) module; make the `init' argument
1678         optional in the scm module's definition, to match the deleted
1679         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
1680
1681 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
1682
1683         Try to detect when people are using one version of libguile and a
1684         different version of ice-9.  People have been skewing things and
1685         sending in bug reports.
1686         * version.scm.in: New file, which the configure script munges to
1687         produce version.scm, which contains the ice-9 config stamp.
1688         * boot-9.scm: Compare the libguile and ice-9 config stamps;
1689         display a warning if the two are different.
1690         * Makefile.am: Install version.scm, but don't distribute it.
1691         Distribute version.scm.in, but don't install it.
1692         * Makefile.in: Regenerated.
1693
1694 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
1695
1696         * slib.scm (slib:warn): Alias for WARN function.
1697
1698 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
1699
1700         * boot-9.scm (struct-printer): Fix off-by-one error in range
1701         check.  Correctly check for struct printer tag.
1702
1703         * expect.scm: Turn this into a module, (ice-9 expect).
1704         (expect-port, expect-timeout, expect-timeout-proc,
1705         expect-eof-proc, expect-char-proc, expect, expect-strings,
1706         expect-select): Make these public definitions.
1707         (expect-strings): Use make-regexp and regexp-exec, instead of
1708         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
1709         that's okay.
1710
1711         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
1712         users in the core, and relies on mildly hairy details of the old
1713         regexp interface.
1714
1715         * test.scm: Re-enable tests asserting that '() is true, and not a
1716         boolean.  This stuff has been true for a while.
1717
1718         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
1719         function names.
1720
1721         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
1722         fixes.
1723
1724 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
1725
1726         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1727         ../configure.in.
1728
1729 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1730
1731         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
1732         vtable and not the one of the struct.
1733
1734 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1735
1736         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
1737         make-struct-printer, set-struct-printer-in-vtable!): New bindings
1738         to support printing of structures.
1739         (record-type-vtable, make-record-type): Add slot to hold printing
1740         function and initialize it with something appropriate.  Removed
1741         commented out printing code.
1742         (record-type-name, record-type-fields): Adjusted slot offsets.
1743         (%print-module): Reduce argument list to "mod" and "port".
1744
1745 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1746
1747         * slib.scm (identity): New function, used by SLIB.
1748
1749 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
1750
1751         * boot-9.scm: signal-handler, alarm-thunk: removed.
1752         don't define ticks-interrupt etc.
1753         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
1754         during call to scm-style-repl.
1755
1756 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
1757
1758         * slib.scm (slib:load): Use primitive-load-path instead of
1759         basic-load.  This is probably wrong, but hopefully the entire
1760         source access system will be revised soon anyway, and this will
1761         make require behave more like Emacs Lisp's require.  If this
1762         breaks something, please let me know.  Maybe this is real dumb.
1763
1764 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
1765
1766         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
1767         * boot-9.scm: If the `regex' feature is present, use the module
1768         (ice-9 regex).
1769
1770 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
1771
1772         * regex.scm: New file.
1773         * Makefile.am (subpkgdata_DATA): Add regex.scm.
1774         * Makefile.in: Regenerated.
1775
1776 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1777
1778         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
1779         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
1780         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
1781         threads.scm: New address for FSF.
1782
1783 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
1784
1785         * debug.scm: Update copyright years; this file has been worked on
1786         in 1997.
1787
1788 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
1789
1790         * expect.scm: use gettimeofday instead of get-internal-real-time
1791         and use a floating point timeout when calling select.  Untested,
1792         since the regex library is currently AWOL.
1793
1794 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
1795
1796         * boot-9.scm (eval-string): Function deleted; it was already
1797         implemented in C, so there's no point in making a divergable copy
1798         here.
1799
1800 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
1801
1802         * Makefile.in: Regenerated, using automake-1.1p.

1809
1810         * boot-9.scm (error-catching-loop): don't read a line from
1811         current input when quit is encountered, the previous change
1812         fixes this too.
1813
1814 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
1815
1816         * boot-9.scm (scm-style-repl): After reading an expression,
1817         consume any trailing newline (perhaps preceded by whitespace), to
1818         avoid screwing up GDB.  More detail in comments.
1819
1820 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
1821
1822         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
1823         the Scheme code like code yet.
1824         * Makefile.in: Resrac,husrched.
1825
1826 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1827
1828         * boot-9.scm (link-dynamic-module): Do not catch errors from
1829         dynamic-link and dynamic-call.  When the shared library exists it
1830         is now assumed to be suitable for a dynamic C module.
1831
1832 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1833
1834         * boot-9.scm (process-use-modules): New function to support the
1835         use-modules macro
1836         (use-modules): throw an error iff one of the requested modules
1837         can't be found.
1838
1839 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>

1844
1845         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1846
1847         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
1848         we're not using AM_INIT_GUILE_MODULE any more.
1849         * Makefile.in: Regeneratitetedrerd.
1850
1851 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
1852
1853         Get 'make dist' to work again.
1854         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1855         * Makefile.in: Regenerated, like two tons of fleas.
1856
1857         Changes for reduced Guile distribution: one configure script,
1858         no plugins.
1859         * configure.in, configure: Removed.
1860         * Makefile.in: Regenerated.
1861
1862 Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>
1863
1864         * boot-9.scm (eval-string, command-line, load-user-init): New
1865         functions.
1866

1868
1869         * boot-9.scm (log10): defined.
1870
1871 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
1872
1873         * expect.scm (expect-select): correct the millisecond timeout
1874         arithmetic (from Marko.Kohtala@ntc.nokia.com).
1875
1876 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
1877
1878         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
1879         instead of in libguile.
1880         (tm:sec etc.) new accessors for broken-down time.
1881         (set-tm:sec etc.) new setters for broken-down time.
1882
1883 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1884
1885         * boot-9.scm (netent:addrtype, servent:port): added missing
1886         procedures.
1887         (netent:net, servent:proto): repaired.
1888         (utsname:sysname etc.): new accessors for uname.
1889
1890 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
1891
1892         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
1893         sockaddr:port): new functions.
1894
1895 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
1896
1897         * boot-9.scm: define accessor procedures for the objects returned
1898         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
1899         passwd:name, where the first component is the name of the C structure
1900         and the second is the unprefixed C member name.)
1901
1902 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
1903
1904         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
1905         setservent): no longer take an argument, it was bogus.
1906
1907 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
1908
1909         * boot-9.scm (scm-error): deleted, reimplemented in C.
1910
1911 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1912
1913         * boot-9.scm (process-define-module): Modified to handle both
1914         keywords and symbols.
1915
1916 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
1917
1918         * slib.scm: update read usage.
1919
1920         * r4rs.scm: update primitive-load usage.
1921         Don't define read-sharp.
1922
1923         * boot-9.scm: use read-hash-extend to install extra read syntax.
1924         (read-sharp): removed.
1925         Adjust usage of primitive-load-path, read, which no longer take
1926         case_i or read-sharp arguments.
1927
1928 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1929
1930         * boot-9.scm: Added loading of session support module.
1931
1932         * debug.scm: Removed `display-application'.  (Replaced by
1933         primitive procedure.)
1934
1935         * boot-9.scm (beautify-user-module!): Don't add the root module
1936         interface to the end of the use-list of the root module.

1939
1940         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
1941

1946 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
1947
1948         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
1949         read gets EOF.
1950         * (exit): alias for quit.
1951
1952 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
1953
1954         * boot-9.scm (error-catching-loop thunk): use a status variable to
1955         return the quit args.
1956         (scm-style-repl): call -quit, passing return value from
1957         error-catching-repl.  Make -quit return its args.
1958         stand-alone-repl: comment out, since it seems unused.
1959
1960         (error-catching-loop thunk): discard trailing junk after a (quit).
1961
1962 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1963
1964         * boot-9.scm: Removed the old printer code.
1965
1966         * r4rs.scm (apply, call-with-current-continuation): Added comment
1967         explaining why apply and call/cc need to be closures.
1968
1969         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
1970         Removed. These definitions are already present in r4rs.scm.
1971
1972         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
1973         stack before printing traced frames; Re-enable trace flag at end
1974         of handlers.
1975
1976 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1977
1978         * debug.scm: Add hook for reset of trace level at abort.
1979
1980         * boot-9.scm (run-hooks): New procedure.
1981         (add-hooks!): New macro.
1982         Change hooks to use these functions.
1983
1984         * debug.scm: *Warning* This feature is a bit premature.  I add
1985         it anyway because 1. it is very useful, and, 2. you can start
1986         making it less premature by complaining to me and by modifying
1987         the source! :-)
1988         (trace): Given one or more procedure objects, trace each one.
1989         Given no arguments, show all traced procedures.
1990         (untrace): Given one or more procedure objects, untrace each one.
1991         Given no arguments, untrace all traced procedures.  The tracing in
1992         Guile have an advantage to most other systems: We don't create new
1993         procedure objects, but mark the procedure objects themselves.
1994         This means that also anonymous and internal procedures can be
1995         traced.
1996
1997         * boot-9.scm (error-catching-loop): Added handling of apply-frame
1998         and exit-frame exceptions.
1999
2000         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
2001         (set-repl-prompt!): Setter for repl prompt.
2002         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
2003         string, display it; if prompt is a thunk, call it and display its
2004         result; otherwise display "> ".
2005         (Change suggested by Roland Orre <orre@nada.kth.se>.)
2006
2007         * r4rs.scm (%load-verbosely): Reverted change to
2008         `module-defined?', since the module system isn't bootstrapped when
2009         we load r4rs.scm.  This is just a temporary fix to make the
2010         repository version runnable.
2011
2012 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2013
2014         * boot-9.scm: Removed the enabling of debug evaluator and
2015         recording of source code positions.  This was placed there for our
2016         convenience, but it has already sneaked into the distribution
2017         once... so we'd better add this in our local copies instead when
2018         we need it.  (These options are normally enabled at the end of
2019         boot-9.scm when loading the debug module.)
2020
2021 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
2022
2023         * boot-9.scm (module-defined?): New function.
2024         (macroexpand-1, macroexpand): Use local-ref instead of defined?
2025         and eval.
2026         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
2027         "defined?".
2028         * slib.scm (defined?): New function to take the place of the
2029         builtin "defined?".  It allways examines the slib module.
2030
2031 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2032
2033         * configure.in: Added AM_MAINTAINER_MODE
2034
2035 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
2036
2037         * boot-9.scm (read-sharp): define directly, don't go through a
2038         %read-sharp layer.
2039
2040 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
2041
2042         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
2043         uniform-vector-set1! which doesn't exist.
2044
2045 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
2046
2047         * boot-9.scm (backtrace): Removed.  (A C version now exists in
2048         backtrace.c.)
2049
2050 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
2051
2052         * boot-9.scm (read-line!, read-delimited!, read-delimited,
2053         read-line): new procedures, see libguile/ChangeLog.
2054
2055 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
2056
2057         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
2058
2059         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
2060         init-dynamic-module, dynamic-maybe-call,
2061         find-and-link-dynamic-module, link-dynamic-module,
2062         try-module-dynamic-link, registered-modules): New definitions for
2063         dynamic linking of modules.
2064         (resolve-module): Try to dynamically link the requested module
2065         after failing to load it as Scheme code.
2066
2067 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
2068
2069         * boot-9.scm (getservbyport, getservbyname): remove stray %.
2070
2071 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
2072
2073         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
2074         that's what it is.
2075
2076         * lineio.scm (make-line-buffering-input-port): Properly test for
2077         the case of an empty buffer list.  The old code assumed that '()
2078         was false.
2079
2080 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
2081
2082         * boot-9.scm (use-modules): New macro (from Marius Vollmer).

2085
2086 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
2087
2088         * boot-9.scm (error-catching-loop): Remove message saying that
2089         typing "$" will put you in the debugger.  This isn't implemented
2090         yet.
2091
2092 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
2093
2094         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
2095         been fixed, so this function is superfluous.
2096         (transform-usage-lambda): Use delq!, not delq-all!.
2097
2098 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
2099
2100         * boot-9.scm (resolve-module): New optional parameter that
2101         controls whether autoloading is attempted or not. Default is #t.
2102         (process-define-module): Don't autoload the defined module.
2103         (try-module-autoload): Don't autoload the directory modules.
2104
2105         * boot-9.scm (process-define-module): Ensure that the-scm-module
2106         is last in the `uses' list to allow shadowing builtin
2107         bindings. All :use-module options are added in the order they
2108         appear in the arguments but before anything already on the list
2109         (such as the-scm-module).
2110
2111 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
2112
2113         * slib.scm (slib-parent-dir): throw error if #f returned from
2114         %search-load-path.
2115
2116 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
2117
2118         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
2119         * Makefile.am, aclocal.m4: New files.
2120         * configure.in: Updated for Automake.
2121
2122 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
2123
2124         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
2125         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
2126         function, use it accordingly.
2127
2128 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
2129
2130         It's an "eval closure", not an "eval thunk."  A thunk is a
2131         function of no arguments.
2132         * boot-9.scm (module-type): Rename module field.
2133         (make-module, eval-in-module, make-root-module,
2134         set-current-module): Uses changed.
2135         (module-eval-closure, set-module-eval-closure!,
2136         root-module-closure): Renamed from module-eval-thunk,
2137         set-module-eval-thunk!, root-module-thunk.
2138         (set-current-module): Change uses of *top-level-lookup-thunk* to
2139         *top-level-eval-closure*.

2142
2143         * slib.scm (slib-parent-dir): Use string-length, not length.
2144         (Thanks to Bernard Urban.)
2145
2146 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2147
2148         * boot-9.scm: The debugging evaluator and recording of positions
2149         aren't enabled by default any longer (they are switched on in
2150         debug.scm).  But during development we want to have them also
2151         *inside* boot-9.scm.  Therefore, two lines are added at the
2152         beginning of boot-9.scm to enable these.
2153
2154         Call `provide' so that `records' are included among the
2155         `*features*'.
2156
2157         The scheme for saving the stack has been adjusted: save-stack is
2158         now commonly available for saving the stack.  Calling `save-stack'
2159         sets a flag `stack-saved?' which prevents overwriting the stack.
2160         `stack-saved?' is reset at `abort'.
2161
2162         Spelling correction: seperate --> separate.
2163
2164         Removed `:'s that had creeped into some comments.
2165
2166         The repl now doesn't print #<unspecified> results any longer
2167         If the user wants to see this, he can do
2168         (assert-repl-print-unspecified #t) in his startup file.
2169
2170         The user now gets a friendly message instead of a backtrace at
2171         error.
2172
2173         Added `before-read-hook'.
2174
2175         Load module (ice-9 emacs) if option `-e' was specified.
2176
2177         (provide): New function.
2178
2179         (error): Save stack at entry, so that Guile entrails won't show up
2180         in backtraces.
2181
2182         (backtrace): New function.
2183
2184         (save-stack): Can now take arbitrary number of stack narrowing
2185         specifier pairs.  The first specifier in a pair controls inner
2186         border, the second the outer border.  A number means cut that
2187         number of frames, a procedure object means cut until that object
2188         is found in operator position in a frame.
2189
2190         * debug.scm: Enable debugging evaluator and recording of positions
2191         by default.
2192
2193         * slib.scm (slib:load): Adapt to the new behavior of
2194         primitive-load: It doesn't any longer try both with and without
2195         ".scm" extension.  (We don't want to use %search-load-path here.)
2196
2197         (implementation-vicinity): New function.  slib requires it
2198
2199         (library-vicinity): Updated.
2200
2201         Load "require.scm" in the library-vicinity.
2202
2203         (install-require-vicinity, install-require-module): New functions.
2204
2205 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
2206
2207         * boot-9.scm (load-from-path): New function.
2208
2209         * boot-9.scm (try-load, basic-try-load, try-load-module,
2210         try-load): Deleted.  I don't think they're being used.
2211
2212         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
2213         so they'll get distributed.
2214
2215         Get Guile to be a little less chatty by default.  The new user
2216         should see as little clutter as possible.
2217         * r4rs.scm (%load-verbosely): Make this #f by default.
2218         * boot-9.scm (scm-repl-verbose): Make this #f by default.
2219         (scm-style-repl): Don't run 'pk' on the value passed to quit.
2220
2221         * r4rs.scm: New file.
2222         * boot-9.scm: Load r4rs.scm, first thing.
2223         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
2224         open-output-file, open-io-file, close-input-port,
2225         close-output-port, close-io-port, call-with-input-file,
2226         call-with-output-file, with-input-from-port, with-output-to-port,
2227         with-error-to-port, with-input-from-file, with-output-to-file,
2228         with-error-to-file, with-input-from-string, with-output-to-string,
2229         with-error-to-string, the-eof-object): Definitions moved to
2230         r4rs.scm.  Not all of them are R4RS, but those that are use those
2231         that are not.
2232         (load, %load-verbosely, %load-announce): Moved, along with code to
2233         set %load-hook, to r4rs.scm.
2234
2235         * test.scm: New file.
2236
2237         * boot-9.scm (integer?): Definition deleted, in favor of the one
2238         present in libguile (which used to be called int?).  I have no
2239         idea why integer? didn't just call int? to begin with.
2240
2241         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
2242         =?, >?, and >=? deleted; they're defined that way by libguile now.
2243
2244         * boot-9.scm (load): Simplified; primitive-load does most of this
2245         work now.
2246         (%load-announce-win): Removed; no longer used.  Set %load-hook to
2247         call %load-announce.
2248
2249 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
2250
2251         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
2252         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
2253         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
2254         components.
2255         (file-is-directory?): use stat:type.
2256
2257 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
2258
2259         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
2260         that's now taken care of in libguile, and in a way compatible with
2261         SCSH (which this isn't).
2262
2263 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2264
2265         * boot-9.scm: Formatting tweaks.
2266
2267 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2268
2269         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
2270         after-error-hook, before-backtrace-hook and after-backtrace-hook
2271         to the error handler.  E.g.: fancy emacs support could plug into
2272         these.
2273         (save-stack): New function.  The stack is now made differently
2274         depending on the stack id.  (The motivation is to make a better
2275         choice regarding what stack frames to present to the user.)
2276         (error-catching-loop): Stack handling code moved outside into
2277         save-stack.
2278
2279 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
2280
2281         * Makefile.in (scm_files): add expect.scm.
2282
2283         * expect.scm: new file ported from guile-iii.
2284
2285         * boot-9.scm: remove handle-system-error, after moving the code into
2286         error-catching-loop.
2287         Don't set 'throw-handler-default property on error keys.
2288         Just interpret (almost) any throw with 4 args as an error throw.
2289         Delete some try-load stuff that was already commented out.
2290
2291         Second thoughts, keep handle-system-error but call it from
2292         error-catching-loop.
2293
2294 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
2295
2296         * boot-9.scm: Doc fixes.
2297         (make-module): Rework for readability.
2298         (make-root-module, make-scm-module): USES argument to make-module
2299         should be '(), not #f.
2300
2301         * boot-9.scm (try-load): %sys-load-path has been renamed to
2302         primitive-load-path; adjust call here.
2303
2304 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2305
2306         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
2307         the stack to the correct place: when it is decided to generate an
2308         error-signal.
2309
2310 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2311
2312         * boot-9.scm (error-catching-loop, signal-handler,
2313         handle-system-error): Backtracing now works for signals aswell;
2314         Backtracing mechanism can now identify the stack root created by
2315         start-stack so that the user isn't exposed to system stack frames.
2316
2317 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2318
2319         * Makefile.in: Added threads.scm.
2320
2321 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2322
2323         * debug.scm (make-enable, make-disable): Simplified.
2324
2325         * boot-9.scm: Renamed %%throw-handler-default -->
2326         throw-handler-default.
2327         ((handle-system-error key . arg-list)): Changed the way errors are
2328         reported.
2329         ((scm-style-repl)): Wrap up the call to eval in a start-stack
2330         acro.
2331         ((error-catching-loop thunk)): Introduce a lazy-catch into
2332         error-catching-loop so that the stack can be captured.
2333
2334 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2335
2336         * mapping.scm (hash-table-mapping): Explicitly request that
2337         make-vector fill new vectors with '(); this will make it easier to
2338         port Guile Scheme code to other Schemes.
2339         * boot-9.scm (make-print-style, make-print-table): Same.
2340
2341 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
2342
2343         * boot-9.scm (load): rewritten again.
2344         Append "." to the default %load-path.
2345         (feature?): new function: checks for a symbol in the features list.
2346         (module-local-variable): remove apparently useless (caddr (list m v
2347         ...))
2348         (%load-announce): minor formatting change.
2349         (file-exists?): use access? if posix is featured.
2350         (file-is-directory?): use stat if i/o-extensions is featured.
2351         (try-module-autoload module-name): use file-exists? before
2352         file-is-directory?
2353
2354 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
2355
2356         * boot-9.scm: Added conditional loading of threads.scm.
2357
2358         * threads.scm: New file.  Modified from the Cygnus-r0.3
2359         distribution.
2360
2361         * boot-9.scm (error-catching-loop): Added handling of key
2362         `switch-repl'.
2363
2364         * boot-9.scm: Name change %%bad-throw --> bad-throw.
2365
2366 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2367
2368         * boot-9.scm (make-record-type, record-constructor): Don't assume
2369         the empty list is false when parsing the argument list.
2370
2371 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2372
2373         * boot-9.scm (signal-handler): Clean up logic.
2374
2375         * boot-9.scm (load): Assume %load-path is always bound.
2376
2377 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2378
2379         * boot-9.scm (error): replace another throw with scm-error.  Throw
2380         to 'misc-error instead of 'error (no need to distinguish these.)
2381         Don't set up 'error as a key.
2382         Set up regex-error as a key, if regex is available.
2383         (signal-handler): use scm-error, not throw.
2384
2385         (%try-load, try-load-with-path, %load, load-with-path,
2386         basic-try-load-with-path, basic-load-with-path,
2387         try-load-module-with-path,load-module-with-path): deleted, since
2388         they seem redundant.
2389         (try-load): define using %try-load, not try-load-with-path.
2390         (load): rewritten.  load tries to open the file directly and
2391         with a .scm extension before searching the library directories
2392         (should "." be added to %load-path?  then load could still open
2393         directly files starting with "/").
2394         (try-module-autoload): use load, not load-with-path.
2395         (%load-indent): deleted, -2 was causing errors.
2396
2397         (%read-sharp): use port-line, not line-number.
2398
2399 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2400
2401         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
2402         straightforward to provide the equivalent functionality using
2403         (catch #t ...), so there's no need for the extra complexity.  2)
2404         Outside the context of a read-eval-print loop (which Guile should
2405         not require) it's not clear we should do anything more complicated
2406         than print an error and exit; the user or REPL can establish
2407         something better if it wants.  3) In that case, it's much more
2408         robust to just do it in the C code.
2409
2410 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
2411
2412         * boot-9.scm (%try-load): define using primitive-load.  Previously
2413         %try-load itself was the primitive.
2414         (load-with-path): use scm-error instead of %load-announce-lossage.
2415         Errors are thrown to 'misc-error instead of 'could-not-load.
2416         (%load-announce-lossage): deleted.
2417
2418 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
2419
2420         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
2421         (make-record-type type-name fields): Temporarily remove support
2422         for printing of records (not possible yet with C printer).
2423
2424 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
2425
2426         * boot-9.scm (file-exists?, file-is-directory): catch only
2427         system-error, not every kind of error.
2428         (scm-error): new procedure.
2429
2430 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2431
2432         * boot-9.scm: Formatting tweaks.
2433
2434 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2435
2436         * boot-9.scm (%%handle-system-error key): remove the code for
2437         SCM-style errors.  handle the case that an unexpected number
2438         of args are supplied.
2439         (%%system-errors): removed.
2440         (error): redefine using a throw with key and 4 args.
2441         ('error): associate 'error, 'error-signal keys with
2442         %%handle-system-error.
2443         (%%default-error-handler): removed.
2444         (signal-handler): throw with 4 args and use the error-signal key.
2445         Create an error message instead of using numerical codes.
2446         (%%bad-throw): call error instead of throw if key not found.
2447
2448 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
2449
2450         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
2451         (%%handle-system-error key): check subr is not #f before printing.
2452         Recognize %s (embed an argument using "display") and
2453         %S (embed an argument using "write").
2454
2455 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
2456
2457         * boot-9.scm (%%handle-system-error key): set args and rest to
2458         the empty list if they are #f.
2459         Initialize out-of-range as an error key.
2460
2461 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
2462
2463         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
2464
2465         * boot-9.scm: remove leading %% from references to '%%system-error.
2466         (%%handle-system-error): don't pass all the thrown arguments when
2467         aborting, just the key and subr.
2468         Remove the code to "Install default handlers for built-in errors."
2469         Remove the definition of the syserror procedure.
2470         Associate 'numerical-overflow with default handler.
2471
2472 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2473
2474         * boot-9.scm: Name change: value-ref --> local-ref
2475         resolved-ref --> nested-ref  Motivation: conformance to the other
2476         dictionary operators: list-ref operates on list, vector-ref
2477         operates on vector, nested-ref operates on nested namespace,
2478         local-ref operates on the local nested namespace.
2479
2480 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
2481
2482         * boot-9.scm (%%handle-system-error): recognise errors thrown
2483         by lgh-error (fill-message etc.)
2484         (fill-message): check first whether args is null.
2485         (fill-message): bug fix and check that args is a list.
2486
2487 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>

2511         Don't use the PLUGIN system to gather information for the

2515         for these.

2518         * Makefile.in (scm_files, aux_files): Write out the list of files
2519         here, where people expect to find them.
