   2
   3         * psyntax.ss (top-level-eval-hook, local-eval-hook): Pass
   4         `(interaction-environment)' as second arg to `eval'.  This is
   5         completely equivalent with the state before the change to eval of
   6         2000-08-11, but we should extend psyntax.ss to be module aware.
   7         (Thanks to Ian Bicking.)
   8
   9         * emacs.scm (emacs-symdoc): Parenthesis fix.
  10

  17         syntactic bindings.
  18

  20         record-modifier, scm-style-repl): Add second arg to eval.
  21         (read-hash-extend #\.): Ditto.  (This is actually a bugfix!)
  22         (eval-in-module): Redefined to be eval and deprecated.
  23
  24         * syncase.scm (eval): Add second arg both in definition and use.

  28
  29         * safe-r5rs.scm (eval): Removed definition.
  30

  35
  36         * boot-9.scm: Added note about dependency in modules.h to
  37         definition of module-type.
  38

  46         *after* all used interfaces has been added.
  47
  48 2000-07-24  Marius Vollmer  <mvo@zagadka.ping.de>

  51
  52 2000-07-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  53
  54         * boot-9.scm (expt):  In case of negative integer exponents return
  55         an exact result if the input paramters were exact.  Thanks to
  56         Mikael for the suggestion.
  57
  58 2000-07-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  59
  60         * boot-9.scm (expt):  Make sure that integer-expt is only called
  61         if the exponent is a non-negative integer.
  62
  63 2000-07-01  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
  64
  65         * boot-9.scm (process-define-module): Bugfix: Only check the CDR
  66         for export args.
  67
  68 2000-06-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
  69

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

 384
 385         * regex.scm (regexp-substitute/global): Handle the end of the
 386         match list and an empty match list identically.  (Thanks to Greg
 387         Badros.)
 388
 389 1999-09-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 390
 391         * debugger.scm ("evaluate"): Replaced `write-line' with calls to
 392         `write' and `newline' since write-line doesn't write but displays.
 393
 394 1999-09-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 395
 396         * debugger.scm ("evaluate"): Newline after no env announcement.
 397
 398         * debug.scm, emacs.scm: Updated copyright notices.
 399
 400         * boot-9.scm (make-autoload-interface): Bugfix.
 401         (top-repl): Autoload debugger.
 402
 403         * debugger.scm ("backtrace"): Don't pass length param to
 404         display-backtrace if it wasn't explicitly given by the user.
 405         (write-frame-long/application): Also print corresponding source
 406         expression.
 407         ("evaluate"): Evaluate in local environment frame, if existent;
 408         Handle errors.
 409
 410 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 411
 412         * format.scm (format:format-work): Use #\tab and #\page instead of
 413         slib:form-feed and slib:tab.  (Thanks to Ceri Storey.)
 414
 415         * format.scm (format:abort): Call error, not slib:error.
 416
 417 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 418
 419         * boot-9.scm (using-readline?): New procedure: Returns #t if
 420         readline is used by the repl run by this thread.
 421         (handle-system-error): Print "Backtrace:" before backtrace since
 422         this is no longer done by display-backtrace.
 423
 424         * debug.scm (frame-number->index): Optionally take stack as
 425         argument.
 426
 427         * debugger.scm: Use the frame number abstraction which allows for
 428         both forward and backward views of the stack
 429         (write-frame-index-short, write-frame-index-long):
 430         Use selector `frame-number';
 431         (select-frame-absolute): Use frame-number->index.
 432         ("backtrace"): Use builtin backtrace printing.
 433         Use (ice-9 debug).
 434         Use readline conditionally.
 435
 436 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 437
 438         * regex.scm (fold-matches, list-matches): New functions.
 439         (regexp-substitute/global): Rewritten again in terms of
 440         list-matches, to get null match behavior correct.
 441
 442         * regex.scm (regexp-substitute/global): Rewrite so that 'post at
 443         the end of the item list actually causes a tail call.  (Thanks to
 444         Jan Nieuwenhuizen.)
 445
 446 1999-09-11  Marius Vollmer  <mvo@zagadka.ping.de>
 447
 448         * readline.scm: Moved to ../guile-readline.
 449
 450         * boot-9.scm (top-repl): Removed code for activating readline.
 451
 452         * Makefile.am: Removed mention of readline.scm.
 453
 454         * Makefile.in: Regenerated.
 455
 456 1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>
 457
 458         Delete the test which compares the configuration date of libguile
 459         with the configuration date of ice-9.  This test yields too many
 460         false positives to be helpful.  For example, if you build Guile
 461         for several architectures but have them all share a "share"
 462         directory (which is supposed to work), then all but one
 463         architecture's Guile will complain that the configuration dates
 464         don't match.  Which is true, but indicates nothing wrong.
 465         * boot-9.scm: Delete code which compares ice-9-config-stamp with
 466         libguile-config-stamp.
 467         * version.scm.in: Delete.
 468         * Makefile.am (ice9_generated): Delete.
 469         (subpkgdata_DATA): Remove ice9_generated.
 470         (EXTRA_DIST): Remove version.scm.in.
 471         * Makefile.in: Regenerate.
 472
 473 1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 474
 475         * debugger.scm: New file: Initial version of the Guile debugger
 476         written by Chris Hanson.  (The debugger isn't finished, but is
 477         included in Guile anyway since it is already quite useful.)
 478
 479         * boot-9.scm (top-repl): Use (ice-9 debug) (ice-9 debugger) (ice-9
 480         session) (ice-9 threads) (ice-9 regex) from guile-user only if
 481         top-repl is called.  This makes startup time for scripts 30% of
 482         what it was before...  Removed redundant code for loading of
 483         readline.
 484
 485         * Makefile.am (ice9_sources): Added debugger.scm.
 486
 487 1999-08-29  Keisuke Nishida  <kxn30@po.cwru.edu>
 488
 489         * boot-9.scm (try-module-autoload): Use %search-load-path.
 490
 491 1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 492
 493         * boot-9.scm: Removed old style hooks.
 494         (inherit-print-state): Rwwritten to use port-with-print-state.
 495
 496 1999-08-20  James Blandy  <jimb@mule.m17n.org>
 497
 498         Remove support for the #/ path list syntax entirely.
 499         * boot-9.scm (read-path-list-notation,
 500         read-path-list-notation-warning): Deleted.
 501         Don't register read-path-list-notation-warning as a reader for
 502         objects starting with '#/'.
 503
 504 1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
 505
 506         GOOPS needs the observer protocol specified for the new module
 507         system.  Here's a simple version for the old module system:
 508         * boot-9.scm (module-observers, module-weak-observers,
 509         module-observer-id, set-module-observers!,
 510         set-module-observer-id!): New accessors.
 511         (module-type): Added slots `observers', `weak-observers' and
 512         `observer-id'.
 513         (module-observe, module-observe-weak, module-unobserve,
 514         module-modified): New procedures.
 515         (module-make-local-var!, module-add!, module-remove!,
 516         module-clear!, module-define!, module-use!): Call module-modified.
 517
 518 1999-07-29  Marius Vollmer  <mvo@zagadka.ping.de>
 519
 520         * boot-9.scm (error-catching-loop): Correct non-RnRS usage of internal
 521         defines.
 522
 523 1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>
 524
 525         * streams.scm: New module, contributed by Michael Livshin.
 526         * Makefile.am (ice9_sources): List it.
 527         * Makefile.in: Regenerated.
 528
 529         * boot-9.scm (read-delimited!): Put the terminator in the correct
 530         position.
 531
 532 1999-06-29  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 533
 534         * readline.scm: Bugfix: Avoid getting the continued-lines prompt
 535         at multiple calls to read.
 536         (promtp2): Variable for continued-lines prompt.
 537         (make-readline-port): Use prompt2.
 538         (set-readline-prompt!): New optional arg which sets
 539         continued-lines prompt.
 540
 541         * boot-9.scm (top-repl): Set/clear readline prompts before/after
 542         reading expressions.
 543
 544 1999-06-18  Jim Blandy  <jimb@savonarola.red-bean.com>
 545
 546         * ls.scm (ls, lls): Handle no arguments as meaning to look in
 547         `(current-module)'. (Patch from Thien-Thi Nguyen.)
 548
 549 1999-06-14  Jim Blandy  <jimb@savonarola.red-bean.com>
 550
 551         * string-fun.scm (split-before-predicate, split-after-predicate,
 552         split-discarding-predicate): Make these public.  (Thanks to
 553         Thien-Thi Nguyen.)
 554
 555         1999-06-13  Gary Houston  <ghouston@easynet.co.uk>
 556
 557         * more changes to expect.scm, to avoid the one-character lookhead
 558         that was introduced to fix the $ problem:
 559
 560         * expect.scm (expect): call the match proc an extra time at end
 561         of file and set the eof? argument appropriately.  call
 562         expect-eof-proc only if the last call didn't match.
 563         * expect.scm (expect-strings): change port to eof? in match proc.
 564         * expect.scm (expect-regexec): take an eof indicator as an argument
 565         instead of a port.
 566
 567 1999-06-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 568
 569         * Makefile.am (ice9_sources): Add popen.scm to list.
 570         * Makefile.in: Regenerated.
 571
 572         Fixes for expect from Gary Houston  <ghouston@easynet.co.uk>:
 573
 574         * expect.scm (expect-regexec): define 'eof-next?'.  I don't
 575         know why it was missing.  also don't peek for end of lines
 576         unless expect-strings-exec-flags contains regexp/noteol.
 577         (expect-strings-exec-flags): initialise to regexp/noteol.
 578
 579         Gary Houston's open-buffer port patches:
 580
 581         1999-04-01  Gary Houston  <ghouston@easynet.co.uk>
 582
 583         * popen.scm: applied fixes from Greg Harvey.  use a guardian
 584         and a gc-thunk so that cleanup is done if a pipe is garbage
 585         collected or closed with close-port.  use a weak hash-table instead of
 586         an alist.
 587
 588         1999-03-20  Gary Houston  <ghouston@easynet.co.uk>
 589
 590         * expect.scm (expect): call the match proc with the port instead.
 591         (expect-strings): use peek-char to get the next char.  this has
 592         the advantage of getting the handling of $ "correct", but the
 593         disadvantage of needing to get (and maybe block for) an extra character
 594         from the port when it may not be needed.  hence:
 595         (expect-strings-exec-flags): new variable/parameter, supplies
 596         flags for regexp-exec.  if this includes regexp/noteol, then
 597         automatic regexp/noteol handling (requiring an extra peeked char)
 598         is enabled.  default is regexp/noteol.
 599         (expect-strings-compile-flags): new variable/parameter, supplies
 600         flags for make-regexp.  default is regexp/newline.
 601
 602         1999-03-15  Gary Houston  <ghouston@easynet.co.uk>
 603
 604         * expect.scm (expect): call the match proc with an extra char,
 605         peeked from the stream.
 606         (expect-strings): build a match proc which takes the extra char.
 607         (expect-regexec): take an extra arg "eof-next?" and use it
 608         to decide whether the regexp/noteol flag should be added.
 609
 610         1999-02-26  Gary Houston  <ghouston@easynet.co.uk>
 611
 612         * boot-9.scm (top-repl): don't flush all ports at exit.
 613         (error-catching-loop): likewise.
 614
 615         1998-12-23  Gary Houston  <ghouston@easynet.co.uk>
 616
 617         * boot-9.scm (scm-style-repl): -read: don't call
 618         consume-trailing-whitespace if val is eof object.  Allows
 619         exiting repl with single control-D.
 620
 621         1998-12-06  Gary Houston  <ghouston@easynet.co.uk>
 622
 623         * boot-9.scm (error-catching-loop): don't force output within
 624         error catching loop after quit received.
 625         (top-repl): flush all ports when the repl terminates.
 626
 627         * boot-9.scm (error-catching-loop): flush all ports before
 628         primitive exit if non-interactive.
 629         force-output on current-error-port if interactive.
 630
 631         * boot-9.scm (reopen-file): deleted.
 632         * popen.scm (open-output-pipe, open-input-pipe): moved from
 633         boot-9.scm.
 634         * popen.scm: new file.
 635
 636 1999-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 637
 638        * boot-9.scm (iota):  replaced by a tail recursive version.
 639        (reverse-iota):  removed.
 640
 641 1999-06-03  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>
 642
 643         * optargs.scm (lambda*): Bugfix: Replaced ARGLIST -->
 644         non-optional-args.  (Thanks to David Lutterkort.)
 645
 646 1999-05-09  Jim Blandy  <jimb@savonarola.red-bean.com>
 647
 648         * string-case.scm: Removed; functions moved to libguile/strop.c
 649         (which could be dynamically linked in the future anyway).
 650         * Makefile.am (ice9_sources): Don't list string-case.scm.
 651         * Makefile.in: Regenerated.
 652         * format.scm: Don't bother importing (ice-9 string-case).
 653
 654 1999-05-02  Jim Blandy  <jimb@savonarola.red-bean.com>
 655
 656         * boot-9.scm (provided?): New function.
 657
 658         * Makefile.am: Add string-case.scm and format.scm to ice9_sources.
 659         * Makefile.in: Regenerated.
 660
 661         * string-case.scm: New file, brought in from SLIB, and adapted to
 662         Guile's module system.
 663
 664         * format.scm: New file, brought in from SLIB, with the following
 665         changes:
 666         (format:format): If the first argument is the format string, stick
 667         a #f on the front of it, so it is now a valid CL format argument
 668         list.  This is easier than changing everyplace else (like the
 669         error formatter) that expects it to be in CL form.  The other
 670         clause which explicitly tests for this case is now dead code.
 671         (format:format-work): Allow `@' and `:' in either order, as per
 672         modern CL behavior.
 673         (format:num->cardinal): Don't assume that an elseless if returns
 674         '() when the condition is false.
 675
 676 1999-04-17  Jim Blandy  <jimb@savonarola.red-bean.com>
 677
 678         * Makefile.in: Regenerated.
 679
 680 1999-04-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 681
 682         * boot-9.scm: Provide 'values.
 683
 684 1999-03-21  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 685
 686         * boot-9.scm (process-define-module, use-syntax): Bugfix:
 687         :use-syntax should add syntax to using module, not current module.
 688         (internal-use-syntax): Removed.
 689
 690 1999-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 691
 692         * session.scm (apropos-internal): Modified to comply with new
 693         argument order for hash-fold.
 694
 695 1999-03-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 696
 697         * boot-9.scm (try-load-module): New procedure.  Broken out from
 698         resolve-module.
 699         (resolve-module): Bugfix: Make it possible for a module at a
 700         deeper level (x y z) to depend on a module on a higher (x y).
 701
 702         This also has the desired side-effect that multiple attempts to
 703         load a module (e.g. with `use-modules') work until source is
 704         actually found for the module (e.g. because the correct catalog
 705         has been added to the load path).
 706
 707         Use try-load-module.
 708
 709 1999-03-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 710
 711         * session.scm (system-module): New procedure.  Used to switch a
 712         module between system and user state.
 713
 714 1999-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 715
 716         * session.scm (apropos-internal): Rewritten using hash-fold.
 717
 718         * emacs.scm, session.scm, slib.scm): Added :no-backtrace in module
 719         definition.
 720
 721 1999-03-14  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 722
 723         * boot-9.scm (make-record-type): Use `set-struct-vtable-name!' to
 724         associate a name to the record type descriptor so that the object
 725         system can create a wrapper class for it.
 726
 727 1999-03-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 728
 729         Improvement of backtraces: Introduces a new stack narrowing
 730         specifier, #t, for the inner cut.  If the inner cut is specified
 731         by #t, `make-stack' will throw away inner stack frames (most
 732         recent calls on call chain) up to but excluding the first user
 733         stack frame encountered.
 734
 735         This specifier is now used in `save-stack' so that the call
 736         `(save-stack)' will get the new behaviour. [It is recommended that
 737         any error reporting functions written by the user have this call
 738         on the outermost expression level (i.e. as a member of the lambda
 739         list).]
 740
 741         Modules are partitioned into "user" and "system" modules. [I know
 742         that some names used here are silly, but I don't have more time to
 743         spend on a better solution, especially considering that the module
 744         system will be replaced.  But if people have better ideas, then
 745         please tell me!]
 746
 747         System modules are created by adding :no-backtrace among the
 748         define-module switches:
 749
 750         (define-module (foo)
 751           :no-backtrace)
 752
 753         Modules which doesn't have the :no-backtrace specifier are user
 754         modules.
 755
 756         A stack frame is classified as a user frame if it has source code
 757         associated with it and if this source code can be proven to come
 758         from a user module.  If it can be proven to come from a system
 759         module it is a system frame.
 760
 761         Frames which can't be classified, e.g. application frames, are cut
 762         away if they occur between system frames, but are left on the
 763         stack if they occur between the last system frame and the first
 764         user frame encountered.  (Note that the first user frame
 765         encountered is the last user code being evaluated!)
 766
 767         In some cases the system part of the call chain is introduced by
 768         frames which should but can't be proven to be system frames.  The
 769         following workaround has been implemented: The cutting proceeds
 770         over application frames where the operator is marked by the
 771         `system-procedure' property.  (This has been used to cut away
 772         generic function dispatch code in the object system.)
 773
 774         * boot-9.scm (set-system-module!): New procedure: Set system/user
 775         status of a module.;
 776         Mark `the-root-module' and `the-scm-module' as system modules.
 777         (process-define-module): Add new keyword :no-backtrace.
 778
 779         * boot-9.scm (environment-module): Bugfixed.
 780         (set-module-eval-closure!): Add a pointer back from the eval
 781         closure to the module.
 782
 783         * emacs.scm (emacs-load): Reset port filename after transfer.
 784
 785 1999-03-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 786
 787         * slib.scm (make-random-state): Added for compatibility.
 788
 789 1999-02-16  Maciej Stachowiak  <mstachow@alum.mit.edu>
 790
 791         * optargs.scm (lambda*): Handle empty argument lists properly.
 792
 793 1999-02-15  Jim Blandy  <jimb@savonarola.red-bean.com>
 794
 795         Fix from Russ McManus:
 796         * getopt-long.scm (parse-option-spec): Store 'optional as the
 797         value-required? field for options that take optional values.
 798         (process-short-option): Grab a value for the option when it takes
 799         either an optional or required value.
 800
 801 1999-02-12  Jim Blandy  <jimb@savonarola.red-bean.com>
 802
 803         * getopt-long.scm: Remove debugging calls to `pk'.
 804
 805         * getopt-long.scm: Return list of ordinary arguments as the value
 806         of the '() key, not `rest'.
 807
 808         A new argument-processing package from Russ McManus.
 809         * getopt-long.scm: New file.
 810         * Makefile.am (ice9_sources): Added getopt-long.scm.
 811         * Makefile.in: Regenerated.
 812
 813 1999-02-09  Maciej Stachowiak  <mstachow@alum.mit.edu>
 814
 815         * optargs.scm: New file.
 816         * Makefile.am (ice9_sources): Add optargs.scm here. Makefile.in
 817         not regenerated because I don't have the right version of Automake.
 818
 819 1999-02-06  Jim Blandy  <jimb@zwingli.cygnus.com>
 820
 821         * and-let*.scm: New file, from Michael Livshin.
 822         * Makefile.am (ice9_sources): Add and-let* here.
 823         * Makefile.in: Regenerated.
 824
 825 1999-01-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 826
 827         * slib.scm (install-require-module): Fixed the kludge which loads
 828         the slib catalog: Doesn't anylonger assume that the feature tested
 829         for isn't loaded.
 830
 831 1998-12-14  Jim Blandy  <jimb@zwingli.cygnus.com>
 832
 833         * Makefile.in: Regenerated.
 834
 835 1998-12-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 836
 837         * boot-9.scm (process-define-module): Reverted the change of
 838         1998-11-23 which caused loading of object code if :use-module was
 839         applied to the module itself.
 840
 841 1998-12-11  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 842
 843         * Makefile.am: Removed setf.scm.
 844
 845         * setf.scm: Removed.  1. It was buggy.  2. It was unschemey.
 846         (These shortcomings were my fault.)
 847
 848 1998-12-10  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 849
 850         * boot-9.scm (environment-module): New procedure.
 851
 852 1998-12-07  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 853
 854         * Makefile.am: Added setf.scm.
 855
 856 1998-12-05  Christian Lynbech  <chl@tbit.dk>
 857
 858         * setf.scm: New file.  Adds the new forms `setf!' and `setter'
 859         which implements generalized references a la Common LISP.
 860
 861 1998-12-02  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 862
 863         * boot-9.scm (process-define-module): Added new specifier
 864         :autoload MODULENAME BINDINGS to the define-module form.
 865         The autoload specifier tells the module system to load the module
 866         MODULENAME at the first occasion that any variable with its name
 867         among BINDINGS is referenced.
 868         (make-autoload-interface): New procedure:  Constructs a stand-in
 869         for the public interface for the module to be autoloaded.
 870
 871 1998-12-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 872
 873         * boot-9.scm (*suppress-old-style-hook-warning*): Set this to #t
 874         if you don't want the old style hook warnings.
 875
 876 1998-12-01  Christian Lynbech  <chl@tbit.dk>
 877
 878         * boot-9.scm (try-using-libtool-name): Fix check on dlname to make
 879         sure that it isn't empty, as it is when we are only buidling
 880         static libraries.
 881
 882 1998-11-27  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 883
 884         * session.scm (arity): New procedure.
 885
 886 1998-11-26  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 887
 888         * boot-9.scm: Use run-hook instead of run-hooks everywhere.
 889
 890 1998-11-26  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 891
 892         * boot-9.scm (run-hooks, add-hook!, remove-hook!): Added temporary
 893         code for backward compatibility until people have had time to
 894         adapt to the new hooks.
 895
 896 1998-11-23  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 897
 898         * boot-9.scm (beautify-user-module!): Beautify also if public
 899         interface is set to the module itself.  In this way we can use
 900         beautify-user-module! to beautify a module prepared for object
 901         code.
 902         (process-define-module): Special case: Try to load object code as
 903         well if a module does :use-module on itself.
 904
 905         * boot-9.scm: Bugfix: Since boot-9.scm is now loaded from
 906         invoke_main_func, we can no longer be sure that all modules have
 907         been registered when boot-9.scm is loaded.
 908         (register-modules): New function: Register and tag modules
 909         registered by scm_register_module_xxx since last call to this
 910         function.  Modules are tagged with the dynamic object passed as
 911         argument.  (Already linked modules should be tagged with #f.)
 912         (init-dynamic-module, link-dynamic-module): Call register-modules
 913         first to register linked modules.
 914
 915         * boot-9.scm (init-dynamic-module): Remove module from
 916         registered-modules as soon as possible in case we are recursively
 917         invoked; Set public interface before doing the dynamic-call.
 918
 919         * boot-9.scm (map-in-order): Removed (replaced by scm_serial_map).
 920         (abort-hook, before-error-hook, after-error-hook,
 921         before-backtrace-hook, after-backtrace-hook, before-read-hook,
 922         after-read-hook, exit-hook): Make hooks with `make-hook'.
 923
 924         * boot-9.scm: Make hooks first class citizens and make them easier
 925         to use from C:
 926         (make-hook, add-hook!, remove-hook!, run-hooks): Moved to
 927         libguile/feature.c.
 928
 929         * boot-9.scm: Added warnings about bindings used in
 930         libguile/modules.c: the-module, set-current-module,
 931         make-modules-in, beautify-user-module!, module-eval-closure.
 932
 933 1998-11-21  Mikael Djurfeldt  <mdj@kenneth>
 934
 935         * boot-9.scm (the-environment): New special form: Returns an
 936         object representing the current local evaluation environment.
 937         This object can be used in `local-eval' and `defined?'.
 938
 939 1998-11-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 940
 941         * boot-9.scm (collect): New syntax.  Similar to begin but returns
 942         a list of the results of all forms in the sequence instead of the
 943         result of the last form.
 944
 945 1998-11-10  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 946
 947         * boot-9.scm (values, call-with-values): Moved here from
 948         syncase.scm.
 949
 950         * syncase.scm (values, call-with-values): Moved to boot-9.scm.
 951
 952         * boot-9.scm (readline-options, readline-enable, readline.disable,
 953         readline-set!: New options interface.
 954
 955         * readline.scm (readline-port): Use readline-options-interface.
 956
 957 1998-11-05  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 958
 959         * boot-9.scm: Set the repl start module in `top-repl' instead of
 960         at the end of boot-9.scm.
 961
 962 1998-11-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 963
 964         * emacs.scm (format): Bugfix: Handle multiple arguments
 965         correctly.  (Thanks to Thien-Thi Nguyen.)
 966
 967 1998-11-01  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 968
 969         * boot-9.scm (exit-hook): New hook: Is run at the very end of an
 970         interactive session.
 971         (top-repl): Run exit-hook on exit.
 972
 973         * readline.scm (readline-port): Maybe read history; Maybe write
 974         history at exit (add to exit-hook).
 975
 976 Fri Oct 30 15:15:37 1998  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 977
 978         * readline.scm (make-readline-port): Bugfixed last change...
 979
 980 1998-10-28  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
 981
 982         * readline.scm (make-readline-port): Don't set prompt to "... " if
 983         read line was empty.
 984
 985 1998-10-19  Jim Blandy  <jimb@zwingli.cygnus.com>
 986
 987         * boot-9.scm, debug.scm, expect.scm, hcons.scm, lineio.scm,
 988         r4rs.scm, slib.scm, threads.scm: Update copyright years.
 989
 990         * getopt-gnu-style.scm, slib.scm: Add copyright notice.
 991
 992         Talked to Stallman.  Actually, the syntax-case copyright is no
 993         problem.  Duh.
 994         * Makefile.am (ice9_sources): Revert last change.
 995         * syncase.scm, psyntax.pp, psyntax.ss: Added again.
 996         * Makefile.in: Regeneretade.
 997
 998         * boot-9.scm: Don't assume that this file is loaded just before
 999         entering a read-eval-print loop.  Turn code to load (ice-9 emacs)
1000         into...
1001         (load-emacs-interface): New function.
1002         (top-repl): Call it, if use-emacs-interface is defined and true.
1003         At this point, we *do* know we're about to enter a REPL.
1004
1005         We can't include Kent Dybvig's syntax-case macro expander in the
1006         core Guile distribution, because we don't have copyright
1007         assignments for this code.  We can certainly distribute them as a
1008         separate package, but Guile should be FSF code.
1009         * syncase.scm, psyntax.pp, psyntax.ss: Removed.
1010         * Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
1011         psyntax.ss.
1012         * Makefile.in: Regenerated.
1013
1014         * Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
1015         * Makefile.in: Regenerated.
1016
1017 1998-10-18  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1018
1019         * boot-9.scm: Added extended read syntax for byte vectors #y(...)
1020         and short vectors #h(...).
1021
1022 1998-10-14  Jim Blandy  <jimb@zwingli.cygnus.com>
1023
1024         * calling.scm (excursion-function-syntax): Use a sequence of
1025         set!'s, not a single multi-variable set!; we removed support for
1026         that syntax a long time ago.  (Thanks to Shuji Narazaki.)
1027
1028 1998-10-12  Jim Blandy  <jimb@zwingli.cygnus.com>
1029
1030         * r4rs.scm (OPEN_READ, OPEN_WRITE, OPEN_BOTH): Don't bother
1031         testing software-type here.  That's the least of our Windows
1032         porting issues, and it's done wrong anyway.
1033
1034 1998-10-09  Jim Blandy  <jimb@zwingli.cygnus.com>
1035
1036         * boot-9.scm (read-path-list-notation-warning): New function:
1037         print a warning the first time we see `#/' notation.
1038
1039         * q.scm (sync-q!, q?, q-remove!, q-push!, enq!): Lots of bugs, and
1040         (eq?  #f '()) assumptions.  Make functions that aren't documented
1041         to return anything else return the queue itself.  (Bug report from
1042         Michael Livshin --- thanks!)
1043
1044 1998-08-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1045
1046         * debug.scm (trace-entry, trace-exit): Removed re-enabling of
1047         trace flag.
1048
1049         * boot-9.scm (make-options): Bugfix: Changed pair? --> list? in
1050         order to allow the empty list as arg.
1051         (error-catching-loop): Use `with-traps' to create a dynamic
1052         context with traps enabled.
1053
1054 1998-08-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1055
1056         * boot-9.scm: Removed (ice-9 regex) from use-list of (guile)
1057         module.
1058         (try-using-libtool-name): Removed dependency on (ice-9 regex).
1059
1060 1998-08-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1061
1062         * boot-9.scm: Make the root module use (ice-9 regex) if
1063         available.  The dynamic linking facilities in boot-9.scm are
1064         currently dependent upon regular expressions.  My change of
1065         1998-07-14 removed (ice-9 regex) from the use-list of the root
1066         module and thereby destroyed dynamic linking.
1067
1068 1998-07-29  Jim Blandy  <jimb@zwingli.cygnus.com>
1069
1070         * Makefile.in: Regenerated using the last public version of
1071         automake, not the hacked Cygnus version.
1072
1073 1998-07-28  Jim Blandy  <jimb@zwingli.cygnus.com>
1074
1075         * Makefile.in: Regenerated, after removing Totoro kludge.
1076
1077 1998-07-28  Jim Blandy  <jimb@totoro.red-bean.com>
1078
1079         * getopt-gnu-style.scm: New file.  (Thanks to Russ McManus.)
1080
1081 1998-07-26  Jim Blandy  <jimb@zwingli.cygnus.com>
1082
1083         * Makefile.in Rebuilt, for config changes in parent dir.
1084
1085 1998-07-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1086
1087         * readline.scm (make-readline-port): Set prompt string to "... "
1088         after first read line.  (Thanks to Richard Polton.)
1089
1090 1998-07-19  Jim Blandy  <jimb@zwingli.cygnus.com>
1091
1092         * lineio.scm (make-line-buffering-input-port): Don't use
1093         ungetc-char-ready?, since we don't provide that function any
1094         more.  The unread-string function doesn't interact properly with
1095         any of the standard I/O functions anyway.  (Thanks to Andrew
1096         Archibald.)
1097
1098         * hcons.scm (hashq-cons-assoc): Don't assume the empty list is
1099         false.  Return false when we cannot find a matching entry in the
1100         list.  (Thanks to Andrew Archibald.)
1101
1102 1998-07-16  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1103
1104         * boot-9.scm (export, export-syntax): New special forms: Export
1105         bindings from a module.  `(export name1 name2 ...)' can be used at
1106         the top of a module (after `define-module') to specify which names
1107         should be exported.  It can be used as an alternative to
1108         `define-public'.  `export-syntax' works equivalently to `export'
1109         but is intended for export of syntactic keywords.
1110         (Thanks to Thien-Thi Nguyen.)

1114         * boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.
1115
1116 1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1117
1118         * boot-9.scm: Let the user start in module `(guile-repl)' instead
1119         of module `(guile)'.  Also make sure that `(guile-repl)' uses
1120         suitable modules.  This change improves Guile stability
1121         substantially since bindings will only be copied from the root
1122         module: If the user redefines builtins in `(guile-repl)' it won't
1123         affect the internal operation of Guile itself.
1124
1125 1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1126
1127         * boot-9.scm (load-module): When loading files from within files
1128         themselves being loaded: Use the directory path of the file being
1129         loaded as root for relative filenames.  (After suggestion by
1130         Steven G. Johnson.)
1131
1132 1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1133
1134         * emacs.scm (emacs-load): New feature: Eval in specified module.
1135
1136 1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1137
1138         * readline.scm: Typo in regex module name.
1139
1140 1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
1141
1142         * readline.scm (apropos-completion-function): regexp-quote text to
1143         be completed.
1144
1145 1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1146
1147         * debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.
1148
1149 1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1150
1151         * boot-9.scm: Check that (current-input-port) is a tty before
1152         enabling readline.  (Thanks to Michael N. Livshin.)
1153
1154 1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1155
1156         * boot-9.scm (use-syntax): Turned into a macro inorder to be
1157         similar in use to `use-modules'.
1158         Example: (use-syntax (ice-9 syncase)) will 1. load the module
1159         (ice-9 syncase), and, 2. install the procedure `syncase' as eval
1160         transformer.
1161         (internal-use-syntax): New procedure.
1162         (process-define-module): Use `internal-use-syntax'.
1163
1164 1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1165
1166         * Makefile.am (ice9_sources): Add emacs.scm.
1167
1168 1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1169
1170         * readline.scm: Use the new readline facilities: Add the
1171         possibility to control input and output ports; Add apropos
1172         completion.
1173
1174         * boot-9.scm: Antirevert Jim's readline code which he reverted
1175         19971027 and adapt it to the current readline interface.
1176
1177         * boot-9.scm (top-repl): Only enable readline if not using the
1178         Emacs interface; Only use repl prompt when using the readline port
1179         from repl-read.  (We don't want to see it when calling `read'.)
1180
1181         * boot-9.scm (remove-hook!): Parenthesis bug.
1182
1183 1998-05-11  Mikael Djurfeldt  <mdj@kenneth>
1184
1185         * boot-9.scm: Load readline module if readline is present.
1186
1187         * readline.scm (apropos-completion-function): New procedure:
1188         Symbolic completion.  (Thanks to Andrew Archibald!)
1189
1190 1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1191
1192         * boot-9.scm (process-define-module): Added keyword use-syntax.
1193
1194 1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1195
1196         * nonblocking.scm: Removed.  libguile is now inherently
1197         nonblocking through the use of scm_internal_select.
1198
1199         * emacs.scm: Removed use of nonblocking.scm.
1200
1201         * gwish.scm, gtcl.scm: Removed.  tcltk.scm has made these
1202         obsolete.
1203
1204 1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>
1205
1206         * runq.scm (runq-control): Corrected spelling of enqueue!.
1207         (Thanks to Karl M. Hegbloom.)
1208
1209 1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>
1210
1211         * boot-9.scm: Added new run-time option interface eval-options.
1212
1213 1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1214
1215         * boot-9.scm (remove-hook!): New macro.  (Thanks to Maciej
1216         Stachowiak.)
1217
1218 1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1219
1220         * threads.scm: Added simple error and signal handler.
1221         (make-thread, begin-handler): Use this handler.  The most
1222         important effect of this is that signals get unmasked.
1223         Previously, when a signal was thrown signals remained masked
1224         (signals get masked when a signal is taken) which influenced other
1225         threads.
1226
1227 1998-01-01  Tim Pierce  <twp@skepsis.com>
1228
1229         A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
1230         * slib.scm (identity): Unmake public.
1231         (slib:eval): Evaluate inside `slib-module'.
1232
1233 1997-12-24  Tim Pierce  <twp@skepsis.com>
1234
1235         * boot-9.scm: Doc fix.
1236
1237         * slib.scm (identity): Made public.
1238         (home-vicinity): New function (from SLIB/Template.scm).
1239
1240 1997-12-13  Tim Pierce  <twp@skepsis.com>
1241
1242         * boot-9.scm (read-line): Rewritten to call %read-line for
1243         improved speed.  Minor user-visible changes: the new functions are
1244         hardwired to treat the LFD character as signifying end-of-line, so
1245         changing `scm-line-incrementors' will no longer affect the
1246         behavior of read-line.  On platforms which do not represent
1247         end-of-line with a LFD character, read-line should behave more
1248         like native line-processing facilities, but there is still a ways
1249         to go here.
1250
1251 Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>
1252
1253         * boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
1254         is now a fluid.
1255
1256 1997-11-28  Tim Pierce  <twp@skepsis.com>
1257
1258         * boot-9.scm (find-and-link-dynamic-module): If a module directory
1259         contains a .la file (a libtool support file), attempt to extract
1260         the shared library name from that file.  If the .la file does not
1261         exist, try to link against a .so file.  Libtool-generated compiled
1262         modules should load more cleanly in Guile now.
1263         (try-using-libtool-name, try-using-sharlib-name): New functions.
1264
1265 Sun Nov  9 06:10:59 1997  Gary Houston  <ghouston@actrix.gen.nz>
1266
1267         * boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
1268         usefully so they will work from a script.
1269
1270 1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>
1271
1272         * boot-9.scm (inherit-print-state): Moved definition to the
1273         neighborhood of the record code.
1274
1275 Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1276
1277         * boot-9.scm: Revert changes to this file from Oct 23.  It turns
1278         out to interact badly with the Emacs support and the Tcl/Tk
1279         support.  It's not a high enough priority at the moment to be
1280         worth fixing.  I'm leaving the other readline support in, though.
1281
1282 Sat Oct 25 14:23:22 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1283
1284         * Makefile.am: Include readline.scm in the list of files to be
1285         installed, so Guile can find it for interactive use.
1286         * Makefile.in: Regenerated.
1287
1288 Thu Oct 23 01:00:33 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1289
1290         Add support for readline function.
1291         * readline.scm: New module.
1292         * boot-9.scm (repl-reader): New function.
1293         (scm-style-repl): Call repl-reader, instead of doing the reading
1294         ourselves.  Remove repl-report-reset; it was never used for
1295         anything.
1296         (top-repl): If we've got the readline primitives, then redefine
1297         repl-reader to use them.
1298         If we've got the readline primitives, import the readline module.
1299
1300         * ls.scm (ls, lls): Don't assume (eq? #f '()).
1301
1302 Wed Oct 22 18:26:57 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1303
1304         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1305         string-fun.scm: Added copyright notices; reformatted.
1306
1307 Thu Oct  9 05:44:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1308
1309         * expect.scm: (expect-regexec): new procedure, use it in
1310         expect-strings to fix the => syntax under the new regex system.
1311         (top): include regex module in define-module statement.
1312
1313 Wed Oct  8 03:16:01 1997  Gary Houston  <ghouston@actrix.gen.nz>
1314
1315         * (error-catching-loop): new local variable "interactive".  if
1316         #f, abort terminates the process.
1317         (set-batch-mode?!, batch-mode?): new closures, defined in
1318         error-catching-loop.  the names are from scsh.
1319
1320 1997-10-06  Marius Vollmer  <mvo@zagadka.ping.de>
1321
1322         * boot-9.scm (inherit-print-state): If NEW-PORT contains a
1323         print-state, throw it away.
1324
1325 Fri Oct  3 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
1326
1327         * boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
1328         `0'.
1329
1330 Thu Oct  2 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
1331
1332         * boot-9.scm (struct-printer, make-struct-printer,
1333         set-struct-printer-in-vtable!, *struct-printer*): Removed.
1334         (record-type-vtable, make-record-type): Don't use make-struct-printer.
1335         (record-type-vtable): User fields "prpr" (printer is no longer a
1336         user field).
1337         (record-type-name, record-type-fields): Decreased slot index by
1338         one; Use `vtable-offset-user'.
1339
1340 Thu Oct  2 12:00:00  Marius Vollmer  <mvo@zagadka.ping.de>
1341
1342         * boot-9.scm (inherit-print-state): New experimental function.
1343
1344 Tue Sep 30 13:12:48 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1345
1346         Suggestion and script from Maciej Stachowiak:
1347         * boot-9.scm: Split off modules into separate, autoloadable files.
1348         This reduces startup time from 10.5s to 5.5s (user cpu).
1349         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
1350         string-fun.scm: New files, containing stuff that used to be in
1351         boot-9.scm.
1352         * Makefile.am (ice9_sources): List new files here, for
1353         distribution and installation.
1354         * Makefile.in: Regenerated.
1355
1356 Mon Sep 29 23:53:55 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1357
1358         * Makefile.in: Regenerated with automake 1.2c.
1359
1360 Mon Sep 29 03:21:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1361
1362         * slib.scm (slib:load): slib:load first tries to load the file
1363         named NAME, then NAME.scm.  On error, report the error occuring at
1364         the first attempt (NAME) rather than the second (NAME.scm).
1365
1366         * boot-9.scm: Bugfix: Hard-solder the print-option procedure into
1367         the make-options macro so that we needn't refer to a global
1368         symbol.
1369
1370 Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1371
1372         * debug.scm: Moved options interface procedures to boot-9.scm.
1373
1374         * boot-9.scm: Define options interface procedures here instead.
1375
1376 Sat Sep 27 20:19:20 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1377
1378         * boot-9.scm (separate-fields-discarding-char,
1379         separate-fields-after-char, separate-fields-before-char): Call
1380         continuation function, RET, as advertised: with each separated
1381         field a separate argument.
1382
1383         * Makefile.in: Regenerated with automake 1.2a.
1384
1385 Sat Sep 20 14:23:53 1997  Mikael Djurfeldt  <mdj@kenneth>
1386
1387         * slib.scm (slib:load): Export.
1388
1389         * boot-9.scm (in-vicinity): Bugfix: Don't add "/" to an empty
1390         vicinity;
1391         Provide defmacro.
1392
1393 Thu Sep 18 01:24:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1394
1395         * r4rs.scm (apply): Set name property to 'apply.
1396
1397 Tue Sep 16 22:09:50 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1398
1399         * boot-9.scm (keyword->symbol, display-usage-report): Changed
1400         length --> string-length.  (Thanks to Aleksandar Bakic.)
1401         (separate-fields-discarding-char, separate-fields-after-char,
1402         separate-fields-before-char): Bugfix from Maciej Stachowiak
1403         <mstachow@mit.edu>.  Thanks!
1404         (try-module-linked): Try to find module among those already
1405         registered.
1406         (try-module-dynamic-link): Removed the first test which
1407         corresponds to a call to `try-module-linked'.
1408         (resolve-module): Resolve modules in this order: 1. Already
1409         registered modules (for example those which have been statically
1410         linked), 2. Try to autoload an .scm-file, 3. Try to dynamically
1411         link a .so-file.
1412
1413 Mon Sep 15 23:39:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1414
1415         * boot-9.scm (iota): Renamed list-reverse! --> reverse!
1416
1417 Thu Sep 11 02:31:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1418
1419         * session.scm (name): New procedure: Gives name of object.
1420         (source): New procedure: Gives source of object.
1421
1422 Wed Sep 10 20:12:45 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1423
1424         * boot-9.scm (primitive-macro?): New procedure.
1425
1426         * slib.scm: Added hack which transfers syntactic information from
1427         the builtin variable `define' to the slib version if module (ice-9
1428         syncase) has been loaded.  This is necessary to get correct
1429         expansion inside the slib module.
1430
1431         * psyntax.ss (build-let, build-named-let): New output
1432         constructors.
1433         (build-lexical-var): Seed gensym with symbolic name.
1434         (self-evaluating?): Add keywords among self-evaluating types.
1435         (let): New core form.
1436         (if): Removed from core language.
1437         (or, and, let, cond): Removed syntactic definitions.
1438         (sc-expand3): New procedure: Expander which takes optional mode
1439         and eval-syntactic-expanders-when arguments.
1440
1441         * syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
1442         Should be used inside the (ice-9 syncase) module with (use-syntax
1443         syncase) and with the current directory containing the psyntax.ss
1444         source.
1445         Added hack to transfer syntactic information from the builtin
1446         variable `define' to the slib version if module (ice-9 slib) has
1447         been loaded.
1448
1449 Fri Sep  5 05:47:36 1997  Mikael Djurfeldt  <mdj@faun.nada.kth.se>
1450
1451         * syncase.scm (sc-interface, sc-expand): Removed hook setup.
1452         (syncase): Publish syntax transformer to be used with
1453         `use-syntax'.
1454         (sc-macro): Use this as the value when publishing macros.
1455
1456         * boot-9.scm (module-type): Added `transformer'.
1457         (make-module): Modified initialization.
1458         (module-transformer, set-module-transformer!): Selector and
1459         mutator for module-associated transformer.
1460         (set-current-module): Use module-transformer to set
1461         `scm:eval-transformer'.
1462         (module-use!): Previous change reverted.
1463         (use-syntax): New function: Install a transformer in current
1464         module.
1465         (sc-interface, sc-expand): Removed! :)
1466
1467 Fri Sep  5 03:09:09 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1468
1469         * emacs.scm (emacs-load): Added new parameter `module'.
1470
1471         * syncase.scm (putprop, getprop): Modified to use the object
1472         properties of the variable object corresponding to the symbol;
1473         This way we can ride on the mechanisms of the module system.
1474         Changed `builtin-variable' calls to `define-public' calls.
1475         Setup the hooks sc-expand and sc-interface.
1476
1477         * boot-9.scm (sc-interface, sc-expand): New builtin variables.
1478         (set-current-module): Switch to and from sc-expand as
1479         scm:eval-transformer when going into and out of modules using
1480         syncase macros.
1481         (module-use!): Set scm:eval-transformer to sc-expand when adding
1482         the syncase interface.
1483
1484 Thu Sep  4 14:57:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1485
1486         * syncase.scm (putprop): Temporary fix which publishes new syntax
1487         globally (the old behaviour was complex and connected to the inner
1488         workings of the current module system).
1489
1490 Wed Sep  3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1491
1492         * psyntax.ss: Updated.
1493         psyntax.pp: Bugfix: Previous version had some leading "t":s cut
1494         off!
1495
1496 Tue Sep  2 00:26:42 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1497
1498         * boot-9.scm (gensym): Removed (replaced by primitive).
1499         (obarray-gensym): Rewritten to use `gensym'.
1500         (gentemp): Rewritten to use `gensym'.
1501
1502 Mon Sep  1 20:08:32 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1503
1504         * gtcl.scm (make-tcl-binder): Rewritten to choose bindings
1505         according to the following priorities:
1506         1. tcl bindings which are present in override-scheme-list
1507         2. bindings from the-scm-module
1508         3. tcl bindings
1509         This way the gtcl module can occur first in the use-list without
1510         disabling the scheme interpreter.
1511         (new-interpreter): New function.
1512
1513         * gwish.scm: Moved initialization code for the-interpreter to
1514         gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
1515         it; Call `new-interpreter'; Don't :use-module (guile).
1516
1517 Thu Aug 28 23:48:53 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1518
1519         * Makefile.in: Regenerated.
1520
1521 Wed Aug 27 11:35:09 1997  Jim Blandy  <jimb@totoro.red-bean.com>
1522
1523         * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1524
1525 Mon Aug 25 22:00:44 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1526
1527         * emacs.scm (object->string, format, error-args->string): New
1528         procedures.
1529         (emacs-frame-eval): Reworked.
1530

1532
1533         * session.scm (apropos-internal): Musn't initialize symbol
1534         accumulator with a constant pair.  That led to mutation of the
1535         source!
1536
1537 Sun Aug 24 01:03:10 1997  Mikael Djurfeldt  <mdj@kenneth>
1538
1539         * session.scm (vector-for-each): Removed.
1540         (apropos): vector-for-each --> array-for-each.
1541         (apropos-internal): New function.  Return list of accessible
1542         symbols matching regexp.
1543
1544         * debug.scm (frame-number->index): New function.  Convert frame
1545         number (as displayed in the backtrace) to frame index (to be used
1546         in stack-ref).
1547
1548         * emacs.scm (emacs-load): New arguments: interactivep: when
1549         non-false, send back results to Emacs; colnum: Column number;
1550         Use modules (ice-9 debug) and (ice-9 session);
1551         (no-stack, no-source): New simple-actions;
1552         (result-to-emacs): New procedure. Sends data to Emacs via the
1553         result protocol;
1554         (get-frame-source, emacs-select-frame, emacs-frame-eval,
1555         emacs-symdoc): New procedures.
1556
1557 Wed Aug 20 13:21:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1558
1559         * emacs.scm (emacs-load): Adjust stack narrowing.
1560         (whitespace-chars): Include #\np.
1561
1562         * syncase.scm: Also turn off debugging evaluator and recording of
1563         procedure names during loading of psyntax.pp.
1564
1565         * psyntax.pp: Removed leading blanks => 800K -> 100K.
1566
1567 Tue Aug 19 02:39:41 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1568
1569         * syncase.scm: Don't tamper with debug mode setting when enabling
1570         macros.  Instead cut the stack with start-stack.
1571         Load psyntax.pp with recording of positions turned off.
1572
1573         * psyntax.pp, psyntax.ss (quasiquote): Changed fx= --> =.
1574
1575         * syncase.scm: New file: Guile-adaption for syntax-case macros.
1576         * psyntax.pp, psyntax.ss: Syntax-case macros, portable version 2 by
1577         R. Kent Dybvig, Oscar Waddell, Bob Hieb and Carl Bruggeman
1578
1579 Mon Aug 18 21:58:25 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1580
1581         * session.scm: New file: Session support.
1582         (apropos): New procedure: List bindings given regexp.
1583
1584 Sat Aug 16 18:44:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
1585
1586         * boot-9.scm: define tms accessors: clock, utime, stime, cutime,
1587         cstime.
1588
1589 Thu Aug 14 19:55:37 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1590
1591         * emacs.scm (emacs-load): Something has changed in the reader so
1592         that we now should set the port line count to the specified value
1593         (linum) instead of (- linum 1).
1594
1595         * slib.scm (slib:load): Use load-from-path instead of
1596         primitive-load-path so that backtraces get narrowed properly at
1597         the top.
1598
1599         * boot-9.scm (top-repl): Save stack already in signal handler in
1600         order to narrow it correctly.
1601         (save-stack): Adjust narrowing tag for the top of load-stacks.
1602
1603 Tue Jul 29 01:18:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
1604
1605         * boot-9.scm (move->fdes, dup->port): use dup->fdes, not primitive-dup.
1606         (dup->fdes): deleted, now done in C.
1607
1608 Sat Jul 26 08:00:42 1997  Gary Houston  <ghouston@actrix.gen.nz>
1609
1610         * boot-9.scm (setenv): new procedure, scsh compatible.
1611
1612 Sat Jul 26 21:30:10 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1613
1614         * boot-9.scm (with-fluids): New macro to go with the
1615         builtin `with-fluids*'.
1616
1617 Thu Jul 24 04:28:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1618
1619         * slib.scm (install-require-module): In newer versions of slib
1620         *catalog* is #f until the first access.  Therefore we call
1621         require:provided? for a random feature if *catalog* is #f.
1622
1623 Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1624
1625         * boot-9.scm: If using emacs interface, enable backtraces
1626         automatically.
1627
1628 Mon Jul 21 06:45:45 1997  Gary Houston  <ghouston@actrix.gen.nz>
1629
1630         * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
1631         dup, fdes->inport, fdes->outport, port->fdes): new procedures.
1632         (duplicate-port): was a C primitive, now it's here.
1633         (move->fdes): allow the first argument to be a file descriptor.
1634         Return the modified port or file descriptor (was unspecified.)
1635
1636 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
1637
1638         Changes to compile under gnu-win32, from Marcus Daniels:
1639         * boot-9.scm (load-user-init): If HOME is unset, provide
1640         a default of /.
1641
1642         * boot-9.scm (define-public): Changed to accomodate Hobbit.
1643
1644 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
1645
1646         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
1647         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
1648         notation, instead of #/ notation.
1649
1650         * expect.scm (expect-strings): Pass regexp/newline flag to
1651         make-regexp.
1652
1653 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
1654
1655         Fix inconsistencies in parsing of #/ style lists.
1656         * boot-9.scm (read-path-list-notation): New function.
1657         (parse-path-symbol): Deleted.  Replaced by above.
1658         Plug in read-path-list-notation as the parser for #/ lists,
1659         instead of the anonymous lambda form calling parse-path-symbol.
1660         (Thanks to Maurizio Vitale.)
1661
1662         * boot-9.scm (make-list): Remove the definition of this function
1663         from the (ice-9 common-list) module; make the `init' argument
1664         optional in the scm module's definition, to match the deleted
1665         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
1666
1667 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
1668
1669         Try to detect when people are using one version of libguile and a
1670         different version of ice-9.  People have been skewing things and
1671         sending in bug reports.
1672         * version.scm.in: New file, which the configure script munges to
1673         produce version.scm, which contains the ice-9 config stamp.
1674         * boot-9.scm: Compare the libguile and ice-9 config stamps;
1675         display a warning if the two are different.
1676         * Makefile.am: Install version.scm, but don't distribute it.
1677         Distribute version.scm.in, but don't install it.
1678         * Makefile.in: Regenerated.
1679
1680 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
1681
1682         * slib.scm (slib:warn): Alias for WARN function.
1683
1684 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
1685
1686         * boot-9.scm (struct-printer): Fix off-by-one error in range
1687         check.  Correctly check for struct printer tag.
1688
1689         * expect.scm: Turn this into a module, (ice-9 expect).
1690         (expect-port, expect-timeout, expect-timeout-proc,
1691         expect-eof-proc, expect-char-proc, expect, expect-strings,
1692         expect-select): Make these public definitions.
1693         (expect-strings): Use make-regexp and regexp-exec, instead of
1694         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
1695         that's okay.
1696
1697         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
1698         users in the core, and relies on mildly hairy details of the old
1699         regexp interface.
1700
1701         * test.scm: Re-enable tests asserting that '() is true, and not a
1702         boolean.  This stuff has been true for a while.
1703
1704         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
1705         function names.
1706
1707         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
1708         fixes.
1709
1710 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
1711
1712         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1713         ../configure.in.
1714
1715 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1716
1717         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
1718         vtable and not the one of the struct.
1719
1720 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1721
1722         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
1723         make-struct-printer, set-struct-printer-in-vtable!): New bindings
1724         to support printing of structures.
1725         (record-type-vtable, make-record-type): Add slot to hold printing
1726         function and initialize it with something appropriate.  Removed
1727         commented out printing code.
1728         (record-type-name, record-type-fields): Adjusted slot offsets.
1729         (%print-module): Reduce argument list to "mod" and "port".
1730
1731 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1732
1733         * slib.scm (identity): New function, used by SLIB.
1734
1735 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
1736
1737         * boot-9.scm: signal-handler, alarm-thunk: removed.
1738         don't define ticks-interrupt etc.
1739         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
1740         during call to scm-style-repl.
1741
1742 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
1743
1744         * slib.scm (slib:load): Use primitive-load-path instead of
1745         basic-load.  This is probably wrong, but hopefully the entire
1746         source access system will be revised soon anyway, and this will
1747         make require behave more like Emacs Lisp's require.  If this
1748         breaks something, please let me know.  Maybe this is real dumb.
1749
1750 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
1751
1752         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
1753         * boot-9.scm: If the `regex' feature is present, use the module
1754         (ice-9 regex).
1755
1756 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
1757
1758         * regex.scm: New file.
1759         * Makefile.am (subpkgdata_DATA): Add regex.scm.
1760         * Makefile.in: Regenerated.
1761
1762 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
1763
1764         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
1765         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
1766         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
1767         threads.scm: New address for FSF.

1769 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
1770
1771         * debug.scm: Update copyright years; this file has been worked on
1772         in 1997.
1773
1774 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
1775
1776         * expect.scm: use gettimeofday instead of get-internal-real-time
1777         and use a floating point timeout when calling select.  Untested,
1778         since the regex library is currently AWOL.
1779
1780 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
1781
1782         * boot-9.scm (eval-string): Function deleted; it was already
1783         implemented in C, so there's no point in making a divergable copy
1784         here.
1785
1786 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
1787
1788         * Makefile.in: Regenerated, using automake-1.1p.

1791
1792         * Makefile.in: Regenerated, using automake-1.1p.

1794 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
1795
1796         * boot-9.scm (error-catching-loop): don't read a line from
1797         current input when quit is encountered, the previous change
1798         fixes this too.
1799
1800 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>

1802         * boot-9.scm (scm-style-repl): After reading an expression,
1803         consume any trailing newline (perhaps preceded by whitespace), to
1804         avoid screwing up GDB.  More detail in comments.
1805
1806 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
1807
1808         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
1809         the Scheme code like code yet.
1810         * Makefile.in: Resrac,husrched.
1811
1812 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1813
1814         * boot-9.scm (link-dynamic-module): Do not catch errors from
1815         dynamic-link and dynamic-call.  When the shared library exists it
1816         is now assumed to be suitable for a dynamic C module.
1817
1818 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
1819
1820         * boot-9.scm (process-use-modules): New function to support the
1821         use-modules macro
1822         (use-modules): throw an error iff one of the requested modules
1823         can't be found.
1824
1825 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
1826

1830
1831         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1832
1833         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
1834         we're not using AM_INIT_GUILE_MODULE any more.
1835         * Makefile.in: Regeneratitetedrerd.
1836
1837 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
1838
1839         Get 'make dist' to work again.
1840         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1841         * Makefile.in: Regenerated, like two tons of fleas.
1842
1843         Changes for reduced Guile distribution: one configure script,
1844         no plugins.
1845         * configure.in, configure: Removed.
1846         * Makefile.in: Regenerated.
1847
1848 Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>
1849
1850         * boot-9.scm (eval-string, command-line, load-user-init): New
1851         functions.
1852

1854
1855         * boot-9.scm (log10): defined.
1856
1857 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
1858
1859         * expect.scm (expect-select): correct the millisecond timeout
1860         arithmetic (from Marko.Kohtala@ntc.nokia.com).
1861
1862 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
1863
1864         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
1865         instead of in libguile.
1866         (tm:sec etc.) new accessors for broken-down time.
1867         (set-tm:sec etc.) new setters for broken-down time.
1868
1869 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
1870
1871         * boot-9.scm (netent:addrtype, servent:port): added missing
1872         procedures.
1873         (netent:net, servent:proto): repaired.
1874         (utsname:sysname etc.): new accessors for uname.
1875
1876 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
1877
1878         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
1879         sockaddr:port): new functions.
1880
1881 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
1882
1883         * boot-9.scm: define accessor procedures for the objects returned
1884         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
1885         passwd:name, where the first component is the name of the C structure
1886         and the second is the unprefixed C member name.)
1887
1888 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
1889
1890         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
1891         setservent): no longer take an argument, it was bogus.
1892
1893 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
1894
1895         * boot-9.scm (scm-error): deleted, reimplemented in C.
1896
1897 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1898
1899         * boot-9.scm (process-define-module): Modified to handle both
1900         keywords and symbols.
1901
1902 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
1903
1904         * slib.scm: update read usage.
1905
1906         * r4rs.scm: update primitive-load usage.
1907         Don't define read-sharp.
1908
1909         * boot-9.scm: use read-hash-extend to install extra read syntax.
1910         (read-sharp): removed.
1911         Adjust usage of primitive-load-path, read, which no longer take
1912         case_i or read-sharp arguments.
1913
1914 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1915
1916         * boot-9.scm: Added loading of session support module.
1917
1918         * debug.scm: Removed `display-application'.  (Replaced by
1919         primitive procedure.)
1920
1921         * boot-9.scm (beautify-user-module!): Don't add the root module
1922         interface to the end of the use-list of the root module.

1925
1926         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
1927

1929
1930         * boot-9.scm: check use-emacs-interface for emacs support.
1931
1932 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
1933
1934         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
1935         read gets EOF.
1936         * (exit): alias for quit.
1937
1938 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
1939
1940         * boot-9.scm (error-catching-loop thunk): use a status variable to
1941         return the quit args.
1942         (scm-style-repl): call -quit, passing return value from
1943         error-catching-repl.  Make -quit return its args.
1944         stand-alone-repl: comment out, since it seems unused.
1945
1946         (error-catching-loop thunk): discard trailing junk after a (quit).
1947
1948 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1949
1950         * boot-9.scm: Removed the old printer code.
1951
1952         * r4rs.scm (apply, call-with-current-continuation): Added comment
1953         explaining why apply and call/cc need to be closures.
1954
1955         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
1956         Removed. These definitions are already present in r4rs.scm.
1957
1958         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
1959         stack before printing traced frames; Re-enable trace flag at end
1960         of handlers.
1961
1962 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1963
1964         * debug.scm: Add hook for reset of trace level at abort.
1965
1966         * boot-9.scm (run-hooks): New procedure.
1967         (add-hooks!): New macro.
1968         Change hooks to use these functions.
1969
1970         * debug.scm: *Warning* This feature is a bit premature.  I add
1971         it anyway because 1. it is very useful, and, 2. you can start
1972         making it less premature by complaining to me and by modifying
1973         the source! :-)
1974         (trace): Given one or more procedure objects, trace each one.
1975         Given no arguments, show all traced procedures.
1976         (untrace): Given one or more procedure objects, untrace each one.
1977         Given no arguments, untrace all traced procedures.  The tracing in
1978         Guile have an advantage to most other systems: We don't create new
1979         procedure objects, but mark the procedure objects themselves.
1980         This means that also anonymous and internal procedures can be
1981         traced.
1982
1983         * boot-9.scm (error-catching-loop): Added handling of apply-frame
1984         and exit-frame exceptions.
1985
1986         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
1987         (set-repl-prompt!): Setter for repl prompt.
1988         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
1989         string, display it; if prompt is a thunk, call it and display its
1990         result; otherwise display "> ".
1991         (Change suggested by Roland Orre <orre@nada.kth.se>.)
1992
1993         * r4rs.scm (%load-verbosely): Reverted change to
1994         `module-defined?', since the module system isn't bootstrapped when
1995         we load r4rs.scm.  This is just a temporary fix to make the
1996         repository version runnable.
1997
1998 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1999
2000         * boot-9.scm: Removed the enabling of debug evaluator and
2001         recording of source code positions.  This was placed there for our
2002         convenience, but it has already sneaked into the distribution
2003         once... so we'd better add this in our local copies instead when
2004         we need it.  (These options are normally enabled at the end of
2005         boot-9.scm when loading the debug module.)
2006
2007 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
2008
2009         * boot-9.scm (module-defined?): New function.
2010         (macroexpand-1, macroexpand): Use local-ref instead of defined?
2011         and eval.
2012         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
2013         "defined?".
2014         * slib.scm (defined?): New function to take the place of the
2015         builtin "defined?".  It allways examines the slib module.
2016
2017 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2018
2019         * configure.in: Added AM_MAINTAINER_MODE
2020
2021 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
2022
2023         * boot-9.scm (read-sharp): define directly, don't go through a
2024         %read-sharp layer.
2025
2026 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
2027
2028         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
2029         uniform-vector-set1! which doesn't exist.
2030
2031 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
2032
2033         * boot-9.scm (backtrace): Removed.  (A C version now exists in
2034         backtrace.c.)
2035
2036 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
2037
2038         * boot-9.scm (read-line!, read-delimited!, read-delimited,
2039         read-line): new procedures, see libguile/ChangeLog.
2040
2041 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
2042
2043         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
2044
2045         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
2046         init-dynamic-module, dynamic-maybe-call,
2047         find-and-link-dynamic-module, link-dynamic-module,
2048         try-module-dynamic-link, registered-modules): New definitions for
2049         dynamic linking of modules.
2050         (resolve-module): Try to dynamically link the requested module
2051         after failing to load it as Scheme code.
2052
2053 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
2054
2055         * boot-9.scm (getservbyport, getservbyname): remove stray %.
2056
2057 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
2058
2059         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
2060         that's what it is.
2061
2062         * lineio.scm (make-line-buffering-input-port): Properly test for
2063         the case of an empty buffer list.  The old code assumed that '()
2064         was false.
2065
2066 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
2067
2068         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
2069         (use-modules <module name> ...) Put the the modules named by
2070         <module name> ... on the use list of the current module.
2071
2072 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
2073
2074         * boot-9.scm (error-catching-loop): Remove message saying that
2075         typing "$" will put you in the debugger.  This isn't implemented
2076         yet.
2077
2078 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
2079
2080         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
2081         been fixed, so this function is superfluous.
2082         (transform-usage-lambda): Use delq!, not delq-all!.
2083
2084 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
2085
2086         * boot-9.scm (resolve-module): New optional parameter that
2087         controls whether autoloading is attempted or not. Default is #t.
2088         (process-define-module): Don't autoload the defined module.
2089         (try-module-autoload): Don't autoload the directory modules.
2090
2091         * boot-9.scm (process-define-module): Ensure that the-scm-module
2092         is last in the `uses' list to allow shadowing builtin
2093         bindings. All :use-module options are added in the order they
2094         appear in the arguments but before anything already on the list
2095         (such as the-scm-module).
2096
2097 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
2098
2099         * slib.scm (slib-parent-dir): throw error if #f returned from
2100         %search-load-path.
2101
2102 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
2103
2104         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
2105         * Makefile.am, aclocal.m4: New files.
2106         * configure.in: Updated for Automake.
2107
2108 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
2109
2110         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
2111         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
2112         function, use it accordingly.
2113
2114 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
2115
2116         It's an "eval closure", not an "eval thunk."  A thunk is a
2117         function of no arguments.
2118         * boot-9.scm (module-type): Rename module field.
2119         (make-module, eval-in-module, make-root-module,
2120         set-current-module): Uses changed.
2121         (module-eval-closure, set-module-eval-closure!,
2122         root-module-closure): Renamed from module-eval-thunk,
2123         set-module-eval-thunk!, root-module-thunk.
2124         (set-current-module): Change uses of *top-level-lookup-thunk* to
2125         *top-level-eval-closure*.
2126
2127 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2128
2129         * slib.scm (slib-parent-dir): Use string-length, not length.
2130         (Thanks to Bernard Urban.)
2131
2132 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2133
2134         * boot-9.scm: The debugging evaluator and recording of positions
2135         aren't enabled by default any longer (they are switched on in
2136         debug.scm).  But during development we want to have them also
2137         *inside* boot-9.scm.  Therefore, two lines are added at the
2138         beginning of boot-9.scm to enable these.
2139
2140         Call `provide' so that `records' are included among the
2141         `*features*'.
2142
2143         The scheme for saving the stack has been adjusted: save-stack is
2144         now commonly available for saving the stack.  Calling `save-stack'
2145         sets a flag `stack-saved?' which prevents overwriting the stack.
2146         `stack-saved?' is reset at `abort'.
2147
2148         Spelling correction: seperate --> separate.
2149
2150         Removed `:'s that had creeped into some comments.
2151
2152         The repl now doesn't print #<unspecified> results any longer
2153         If the user wants to see this, he can do
2154         (assert-repl-print-unspecified #t) in his startup file.
2155
2156         The user now gets a friendly message instead of a backtrace at
2157         error.
2158
2159         Added `before-read-hook'.
2160
2161         Load module (ice-9 emacs) if option `-e' was specified.
2162
2163         (provide): New function.
2164
2165         (error): Save stack at entry, so that Guile entrails won't show up
2166         in backtraces.
2167
2168         (backtrace): New function.
2169
2170         (save-stack): Can now take arbitrary number of stack narrowing
2171         specifier pairs.  The first specifier in a pair controls inner
2172         border, the second the outer border.  A number means cut that
2173         number of frames, a procedure object means cut until that object
2174         is found in operator position in a frame.
2175
2176         * debug.scm: Enable debugging evaluator and recording of positions
2177         by default.
2178
2179         * slib.scm (slib:load): Adapt to the new behavior of
2180         primitive-load: It doesn't any longer try both with and without
2181         ".scm" extension.  (We don't want to use %search-load-path here.)
2182
2183         (implementation-vicinity): New function.  slib requires it
2184
2185         (library-vicinity): Updated.
2186
2187         Load "require.scm" in the library-vicinity.
2188
2189         (install-require-vicinity, install-require-module): New functions.
2190
2191 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
2192
2193         * boot-9.scm (load-from-path): New function.
2194
2195         * boot-9.scm (try-load, basic-try-load, try-load-module,
2196         try-load): Deleted.  I don't think they're being used.
2197
2198         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
2199         so they'll get distributed.
2200
2201         Get Guile to be a little less chatty by default.  The new user
2202         should see as little clutter as possible.
2203         * r4rs.scm (%load-verbosely): Make this #f by default.
2204         * boot-9.scm (scm-repl-verbose): Make this #f by default.
2205         (scm-style-repl): Don't run 'pk' on the value passed to quit.
2206
2207         * r4rs.scm: New file.
2208         * boot-9.scm: Load r4rs.scm, first thing.
2209         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
2210         open-output-file, open-io-file, close-input-port,
2211         close-output-port, close-io-port, call-with-input-file,
2212         call-with-output-file, with-input-from-port, with-output-to-port,
2213         with-error-to-port, with-input-from-file, with-output-to-file,
2214         with-error-to-file, with-input-from-string, with-output-to-string,
2215         with-error-to-string, the-eof-object): Definitions moved to
2216         r4rs.scm.  Not all of them are R4RS, but those that are use those
2217         that are not.
2218         (load, %load-verbosely, %load-announce): Moved, along with code to
2219         set %load-hook, to r4rs.scm.
2220
2221         * test.scm: New file.
2222
2223         * boot-9.scm (integer?): Definition deleted, in favor of the one
2224         present in libguile (which used to be called int?).  I have no
2225         idea why integer? didn't just call int? to begin with.
2226
2227         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
2228         =?, >?, and >=? deleted; they're defined that way by libguile now.
2229
2230         * boot-9.scm (load): Simplified; primitive-load does most of this
2231         work now.
2232         (%load-announce-win): Removed; no longer used.  Set %load-hook to
2233         call %load-announce.
2234
2235 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
2236
2237         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
2238         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
2239         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
2240         components.
2241         (file-is-directory?): use stat:type.
2242
2243 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
2244
2245         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
2246         that's now taken care of in libguile, and in a way compatible with
2247         SCSH (which this isn't).
2248
2249 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2250
2251         * boot-9.scm: Formatting tweaks.
2252
2253 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
2254
2255         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
2256         after-error-hook, before-backtrace-hook and after-backtrace-hook
2257         to the error handler.  E.g.: fancy emacs support could plug into
2258         these.
2259         (save-stack): New function.  The stack is now made differently
2260         depending on the stack id.  (The motivation is to make a better
2261         choice regarding what stack frames to present to the user.)
2262         (error-catching-loop): Stack handling code moved outside into
2263         save-stack.
2264
2265 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
2266
2267         * Makefile.in (scm_files): add expect.scm.
2268
2269         * expect.scm: new file ported from guile-iii.
2270
2271         * boot-9.scm: remove handle-system-error, after moving the code into
2272         error-catching-loop.
2273         Don't set 'throw-handler-default property on error keys.
2274         Just interpret (almost) any throw with 4 args as an error throw.
2275         Delete some try-load stuff that was already commented out.
2276
2277         Second thoughts, keep handle-system-error but call it from
2278         error-catching-loop.
2279
2280 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
2281
2282         * boot-9.scm: Doc fixes.
2283         (make-module): Rework for readability.
2284         (make-root-module, make-scm-module): USES argument to make-module
2285         should be '(), not #f.
2286
2287         * boot-9.scm (try-load): %sys-load-path has been renamed to
2288         primitive-load-path; adjust call here.
2289
2290 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2291
2292         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
2293         the stack to the correct place: when it is decided to generate an
2294         error-signal.
2295
2296 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2297
2298         * boot-9.scm (error-catching-loop, signal-handler,
2299         handle-system-error): Backtracing now works for signals aswell;
2300         Backtracing mechanism can now identify the stack root created by
2301         start-stack so that the user isn't exposed to system stack frames.
2302
2303 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2304
2305         * Makefile.in: Added threads.scm.
2306
2307 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2308
2309         * debug.scm (make-enable, make-disable): Simplified.
2310
2311         * boot-9.scm: Renamed %%throw-handler-default -->
2312         throw-handler-default.
2313         ((handle-system-error key . arg-list)): Changed the way errors are
2314         reported.
2315         ((scm-style-repl)): Wrap up the call to eval in a start-stack
2316         acro.
2317         ((error-catching-loop thunk)): Introduce a lazy-catch into
2318         error-catching-loop so that the stack can be captured.
2319
2320 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2321
2322         * mapping.scm (hash-table-mapping): Explicitly request that
2323         make-vector fill new vectors with '(); this will make it easier to
2324         port Guile Scheme code to other Schemes.
2325         * boot-9.scm (make-print-style, make-print-table): Same.
2326
2327 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
2328
2329         * boot-9.scm (load): rewritten again.
2330         Append "." to the default %load-path.
2331         (feature?): new function: checks for a symbol in the features list.
2332         (module-local-variable): remove apparently useless (caddr (list m v
2333         ...))
2334         (%load-announce): minor formatting change.
2335         (file-exists?): use access? if posix is featured.
2336         (file-is-directory?): use stat if i/o-extensions is featured.
2337         (try-module-autoload module-name): use file-exists? before
2338         file-is-directory?
2339
2340 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
2341
2342         * boot-9.scm: Added conditional loading of threads.scm.
2343
2344         * threads.scm: New file.  Modified from the Cygnus-r0.3
2345         distribution.
2346
2347         * boot-9.scm (error-catching-loop): Added handling of key
2348         `switch-repl'.
2349
2350         * boot-9.scm: Name change %%bad-throw --> bad-throw.
2351
2352 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2353
2354         * boot-9.scm (make-record-type, record-constructor): Don't assume
2355         the empty list is false when parsing the argument list.
2356
2357 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2358
2359         * boot-9.scm (signal-handler): Clean up logic.
2360
2361         * boot-9.scm (load): Assume %load-path is always bound.
2362
2363 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2364
2365         * boot-9.scm (error): replace another throw with scm-error.  Throw
2366         to 'misc-error instead of 'error (no need to distinguish these.)
2367         Don't set up 'error as a key.
2368         Set up regex-error as a key, if regex is available.
2369         (signal-handler): use scm-error, not throw.
2370
2371         (%try-load, try-load-with-path, %load, load-with-path,
2372         basic-try-load-with-path, basic-load-with-path,
2373         try-load-module-with-path,load-module-with-path): deleted, since
2374         they seem redundant.
2375         (try-load): define using %try-load, not try-load-with-path.
2376         (load): rewritten.  load tries to open the file directly and
2377         with a .scm extension before searching the library directories
2378         (should "." be added to %load-path?  then load could still open
2379         directly files starting with "/").
2380         (try-module-autoload): use load, not load-with-path.
2381         (%load-indent): deleted, -2 was causing errors.
2382
2383         (%read-sharp): use port-line, not line-number.
2384
2385 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2386
2387         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
2388         straightforward to provide the equivalent functionality using
2389         (catch #t ...), so there's no need for the extra complexity.  2)
2390         Outside the context of a read-eval-print loop (which Guile should
2391         not require) it's not clear we should do anything more complicated
2392         than print an error and exit; the user or REPL can establish
2393         something better if it wants.  3) In that case, it's much more
2394         robust to just do it in the C code.
2395
2396 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
2397
2398         * boot-9.scm (%try-load): define using primitive-load.  Previously
2399         %try-load itself was the primitive.
2400         (load-with-path): use scm-error instead of %load-announce-lossage.
2401         Errors are thrown to 'misc-error instead of 'could-not-load.
2402         (%load-announce-lossage): deleted.
2403
2404 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
2405
2406         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
2407         (make-record-type type-name fields): Temporarily remove support
2408         for printing of records (not possible yet with C printer).
2409
2410 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
2411
2412         * boot-9.scm (file-exists?, file-is-directory): catch only
2413         system-error, not every kind of error.
2414         (scm-error): new procedure.
2415
2416 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
2417
2418         * boot-9.scm: Formatting tweaks.
2419
2420 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
2421
2422         * boot-9.scm (%%handle-system-error key): remove the code for
2423         SCM-style errors.  handle the case that an unexpected number
2424         of args are supplied.
2425         (%%system-errors): removed.
2426         (error): redefine using a throw with key and 4 args.
2427         ('error): associate 'error, 'error-signal keys with
2428         %%handle-system-error.
2429         (%%default-error-handler): removed.
2430         (signal-handler): throw with 4 args and use the error-signal key.
2431         Create an error message instead of using numerical codes.
2432         (%%bad-throw): call error instead of throw if key not found.
2433
2434 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
2435
2436         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
2437         (%%handle-system-error key): check subr is not #f before printing.
2438         Recognize %s (embed an argument using "display") and
2439         %S (embed an argument using "write").
2440
2441 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
2442
2443         * boot-9.scm (%%handle-system-error key): set args and rest to
2444         the empty list if they are #f.
2445         Initialize out-of-range as an error key.
2446
2447 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
2448
2449         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
2450
2451         * boot-9.scm: remove leading %% from references to '%%system-error.
2452         (%%handle-system-error): don't pass all the thrown arguments when
2453         aborting, just the key and subr.
2454         Remove the code to "Install default handlers for built-in errors."
2455         Remove the definition of the syserror procedure.
2456         Associate 'numerical-overflow with default handler.
2457
2458 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
2459
2460         * boot-9.scm: Name change: value-ref --> local-ref
2461         resolved-ref --> nested-ref  Motivation: conformance to the other
2462         dictionary operators: list-ref operates on list, vector-ref
2463         operates on vector, nested-ref operates on nested namespace,
2464         local-ref operates on the local nested namespace.
2465
2466 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
2467
2468         * boot-9.scm (%%handle-system-error): recognise errors thrown
2469         by lgh-error (fill-message etc.)
2470         (fill-message): check first whether args is null.
2471         (fill-message): bug fix and check that args is a list.
2472
2473 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
2474
2475         * boot-9.scm: %load-path is initialized in C code now.
2476         (implementation-vicinity, parse-path): Deleted, along with code to
2477         initialize %load-path.
2478
2479         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
2480         "/", use one to separate it from the file.
2481
2482 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
2483

2497         Don't use the PLUGIN system to gather information for the

2501         for these.

2504         * Makefile.in (scm_files, aux_files): Write out the list of files
2505         here, where people expect to find them.
