ice-9/ChangeLog

   1 1998-07-16  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
   2
   3         * boot-9.scm (export, export-syntax): New special forms: Export
   4         bindings from a module.  `(export name1 name2 ...)' can be used at
   5         the top of a module (after `define-module') to specify which names
   6         should be exported.  It can be used as an alternative to
   7         `define-public'.  `export-syntax' works equivalently to `export'
   8         but is intended for export of syntactic keywords.
   9         (Thanks to Thien-Thi Nguyen.)
  10
  11 1998-07-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
  12
  13         * boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.
  14
  15 1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  16
  17         * boot-9.scm: Let the user start in module `(guile-repl)' instead
  18         of module `(guile)'.  Also make sure that `(guile-repl)' uses
  19         suitable modules.  This change improves Guile stability
  20         substantially since bindings will only be copied from the root
  21         module: If the user redefines builtins in `(guile-repl)' it won't
  22         affect the internal operation of Guile itself.
  23
  24 1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
  25
  26         * boot-9.scm (load-module): When loading files from within files
  27         themselves being loaded: Use the directory path of the file being
  28         loaded as root for relative filenames.  (After suggestion by
  29         Steven G. Johnson.)
  30
  31 1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  32
  33         * emacs.scm (emacs-load): New feature: Eval in specified module.
  34
  35 1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  36
  37         * readline.scm: Typo in regex module name.
  38
  39 1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>
  40
  41         * readline.scm (apropos-completion-function): regexp-quote text to
  42         be completed.
  43
  44 1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  45
  46         * debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.
  47
  48 1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  49
  50         * boot-9.scm: Check that (current-input-port) is a tty before
  51         enabling readline.  (Thanks to Michael N. Livshin.)
  52
  53 1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  54
  55         * boot-9.scm (use-syntax): Turned into a macro inorder to be
  56         similar in use to `use-modules'.
  57         Example: (use-syntax (ice-9 syncase)) will 1. load the module
  58         (ice-9 syncase), and, 2. install the procedure `syncase' as eval
  59         transformer.
  60         (internal-use-syntax): New procedure.
  61         (process-define-module): Use `internal-use-syntax'.
  62
  63 1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  64
  65         * Makefile.am (ice9_sources): Add emacs.scm.
  66
  67 1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  68
  69         * readline.scm: Use the new readline facilities: Add the
  70         possibility to control input and output ports; Add apropos
  71         completion.
  72
  73         * boot-9.scm: Antirevert Jim's readline code which he reverted
  74         19971027 and adapt it to the current readline interface.
  75
  76         * boot-9.scm (top-repl): Only enable readline if not using the
  77         Emacs interface; Only use repl prompt when using the readline port
  78         from repl-read.  (We don't want to see it when calling `read'.)
  79
  80         * boot-9.scm (remove-hook!): Parenthesis bug.
  81
  82 1998-05-11  Mikael Djurfeldt  <mdj@kenneth>
  83
  84         * boot-9.scm: Load readline module if readline is present.
  85
  86         * readline.scm (apropos-completion-function): New procedure:
  87         Symbolic completion.  (Thanks to Andrew Archibald!)
  88
  89 1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  90
  91         * boot-9.scm (process-define-module): Added keyword use-syntax.
  92
  93 1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  94
  95         * nonblocking.scm: Removed.  libguile is now inherently
  96         nonblocking through the use of scm_internal_select.
  97
  98         * emacs.scm: Removed use of nonblocking.scm.
  99
 100         * gwish.scm, gtcl.scm: Removed.  tcltk.scm has made these
 101         obsolete.
 102
 103 1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>
 104
 105         * runq.scm (runq-control): Corrected spelling of enqueue!.
 106         (Thanks to Karl M. Hegbloom.)
 107
 108 1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>
 109
 110         * boot-9.scm: Added new run-time option interface eval-options.
 111
 112 1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 113
 114         * boot-9.scm (remove-hook!): New macro.  (Thanks to Maciej
 115         Stachowiak.)
 116
 117 1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 118
 119         * threads.scm: Added simple error and signal handler.
 120         (make-thread, begin-handler): Use this handler.  The most
 121         important effect of this is that signals get unmasked.
 122         Previously, when a signal was thrown signals remained masked
 123         (signals get masked when a signal is taken) which influenced other
 124         threads.
 125
 126 1998-01-01  Tim Pierce  <twp@skepsis.com>
 127
 128         A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
 129         * slib.scm (identity): Unmake public.
 130         (slib:eval): Evaluate inside `slib-module'.
 131
 132 1997-12-24  Tim Pierce  <twp@skepsis.com>
 133
 134         * boot-9.scm: Doc fix.
 135
 136         * slib.scm (identity): Made public.
 137         (home-vicinity): New function (from SLIB/Template.scm).
 138
 139 1997-12-13  Tim Pierce  <twp@skepsis.com>
 140
 141 *       * boot-9.scm (read-line): Rewritten to call %read-line for
 142         improved speed.  Minor user-visible changes: the new functions are
 143         hardwired to treat the LFD character as signifying end-of-line, so
 144         changing `scm-line-incrementors' will no longer affect the
 145         behavior of read-line.  On platforms which do not represent
 146         end-of-line with a LFD character, read-line should behave more
 147         like native line-processing facilities, but there is still a ways
 148         to go here.
 149
 150 Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>
 151
 152         * boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
 153         is now a fluid.
 154
 155 1997-11-28  Tim Pierce  <twp@skepsis.com>
 156
 157         * boot-9.scm (find-and-link-dynamic-module): If a module directory
 158         contains a .la file (a libtool support file), attempt to extract
 159         the shared library name from that file.  If the .la file does not
 160         exist, try to link against a .so file.  Libtool-generated compiled
 161         modules should load more cleanly in Guile now.
 162         (try-using-libtool-name, try-using-sharlib-name): New functions.
 163
 164 Sun Nov  9 06:10:59 1997  Gary Houston  <ghouston@actrix.gen.nz>
 165
 166         * boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
 167         usefully so they will work from a script.
 168
 169 1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>
 170
 171         * boot-9.scm (inherit-print-state): Moved definition to the
 172         neighborhood of the record code.
 173
 174 Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 175
 176         * boot-9.scm: Revert changes to this file from Oct 23.  It turns
 177         out to interact badly with the Emacs support and the Tcl/Tk
 178         support.  It's not a high enough priority at the moment to be
 179         worth fixing.  I'm leaving the other readline support in, though.
 180
 181 Sat Oct 25 14:23:22 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 182
 183         * Makefile.am: Include readline.scm in the list of files to be
 184         installed, so Guile can find it for interactive use.
 185         * Makefile.in: Regenerated.
 186
 187 Thu Oct 23 01:00:33 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 188
 189         Add support for readline function.
 190         * readline.scm: New module.
 191         * boot-9.scm (repl-reader): New function.
 192         (scm-style-repl): Call repl-reader, instead of doing the reading
 193         ourselves.  Remove repl-report-reset; it was never used for
 194         anything.
 195         (top-repl): If we've got the readline primitives, then redefine
 196         repl-reader to use them.
 197         If we've got the readline primitives, import the readline module.
 198
 199         * ls.scm (ls, lls): Don't assume (eq? #f '()).
 200
 201 Wed Oct 22 18:26:57 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 202
 203         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
 204         string-fun.scm: Added copyright notices; reformatted.
 205
 206 Thu Oct  9 05:44:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 207
 208         * expect.scm: (expect-regexec): new procedure, use it in
 209         expect-strings to fix the => syntax under the new regex system.
 210         (top): include regex module in define-module statement.
 211
 212 Wed Oct  8 03:16:01 1997  Gary Houston  <ghouston@actrix.gen.nz>
 213
 214         * (error-catching-loop): new local variable "interactive".  if
 215         #f, abort terminates the process.
 216         (set-batch-mode?!, batch-mode?): new closures, defined in
 217         error-catching-loop.  the names are from scsh.
 218
 219 1997-10-06  Marius Vollmer  <mvo@zagadka.ping.de>
 220
 221         * boot-9.scm (inherit-print-state): If NEW-PORT contains a
 222         print-state, throw it away.
 223
 224 Fri Oct  3 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
 225
 226         * boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
 227         `0'.
 228
 229 Thu Oct  2 12:00:00  Mikael Djurfeldt  <mdj@nada.kth.se>
 230
 231         * boot-9.scm (struct-printer, make-struct-printer,
 232         set-struct-printer-in-vtable!, *struct-printer*): Removed.
 233         (record-type-vtable, make-record-type): Don't use make-struct-printer.
 234         (record-type-vtable): User fields "prpr" (printer is no longer a
 235         user field).
 236         (record-type-name, record-type-fields): Decreased slot index by
 237         one; Use `vtable-offset-user'.
 238
 239 Thu Oct  2 12:00:00  Marius Vollmer  <mvo@zagadka.ping.de>
 240
 241         * boot-9.scm (inherit-print-state): New experimental function.
 242
 243 Tue Sep 30 13:12:48 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 244
 245         Suggestion and script from Maciej Stachowiak:
 246         * boot-9.scm: Split off modules into separate, autoloadable files.
 247         This reduces startup time from 10.5s to 5.5s (user cpu).
 248         * calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
 249         string-fun.scm: New files, containing stuff that used to be in
 250         boot-9.scm.
 251         * Makefile.am (ice9_sources): List new files here, for
 252         distribution and installation.
 253         * Makefile.in: Regenerated.
 254
 255 Mon Sep 29 23:53:55 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 256
 257         * Makefile.in: Regenerated with automake 1.2c.
 258
 259 Mon Sep 29 03:21:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 260
 261         * slib.scm (slib:load): slib:load first tries to load the file
 262         named NAME, then NAME.scm.  On error, report the error occuring at
 263         the first attempt (NAME) rather than the second (NAME.scm).
 264
 265         * boot-9.scm: Bugfix: Hard-solder the print-option procedure into
 266         the make-options macro so that we needn't refer to a global
 267         symbol.
 268
 269 Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 270
 271         * debug.scm: Moved options interface procedures to boot-9.scm.
 272
 273         * boot-9.scm: Define options interface procedures here instead.
 274
 275 Sat Sep 27 20:19:20 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 276
 277         * boot-9.scm (separate-fields-discarding-char,
 278         separate-fields-after-char, separate-fields-before-char): Call
 279         continuation function, RET, as advertised: with each separated
 280         field a separate argument.
 281
 282         * Makefile.in: Regenerated with automake 1.2a.
 283
 284 Sat Sep 20 14:23:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 285
 286         * slib.scm (slib:load): Export.
 287
 288         * boot-9.scm (in-vicinity): Bugfix: Don't add "/" to an empty
 289         vicinity;
 290         Provide defmacro.
 291
 292 Thu Sep 18 01:24:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 293
 294         * r4rs.scm (apply): Set name property to 'apply.
 295
 296 Tue Sep 16 22:09:50 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 297
 298         * boot-9.scm (keyword->symbol, display-usage-report): Changed
 299         length --> string-length.  (Thanks to Aleksandar Bakic.)
 300         (separate-fields-discarding-char, separate-fields-after-char,
 301         separate-fields-before-char): Bugfix from Maciej Stachowiak
 302         <mstachow@mit.edu>.  Thanks!
 303         (try-module-linked): Try to find module among those already
 304         registered.
 305         (try-module-dynamic-link): Removed the first test which
 306         corresponds to a call to `try-module-linked'.
 307         (resolve-module): Resolve modules in this order: 1. Already
 308         registered modules (for example those which have been statically
 309         linked), 2. Try to autoload an .scm-file, 3. Try to dynamically
 310         link a .so-file.
 311
 312 Mon Sep 15 23:39:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 313
 314         * boot-9.scm (iota): Renamed list-reverse! --> reverse!
 315
 316 Thu Sep 11 02:31:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 317
 318         * session.scm (name): New procedure: Gives name of object.
 319         (source): New procedure: Gives source of object.
 320
 321 Wed Sep 10 20:12:45 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 322
 323 *       * boot-9.scm (primitive-macro?): New procedure.
 324
 325         * slib.scm: Added hack which transfers syntactic information from
 326         the builtin variable `define' to the slib version if module (ice-9
 327         syncase) has been loaded.  This is necessary to get correct
 328         expansion inside the slib module.
 329
 330         * psyntax.ss (build-let, build-named-let): New output
 331         constructors.
 332         (build-lexical-var): Seed gensym with symbolic name.
 333         (self-evaluating?): Add keywords among self-evaluating types.
 334         (let): New core form.
 335         (if): Removed from core language.
 336         (or, and, let, cond): Removed syntactic definitions.
 337         (sc-expand3): New procedure: Expander which takes optional mode
 338         and eval-syntactic-expanders-when arguments.
 339
 340         * syncase.scm (psyncomp): New procedure: Recompiles psyntax.pp.
 341         Should be used inside the (ice-9 syncase) module with (use-syntax
 342         syncase) and with the current directory containing the psyntax.ss
 343         source.
 344         Added hack to transfer syntactic information from the builtin
 345         variable `define' to the slib version if module (ice-9 slib) has
 346         been loaded.
 347
 348 Fri Sep  5 05:47:36 1997  Mikael Djurfeldt  <mdj@faun.nada.kth.se>
 349
 350         * syncase.scm (sc-interface, sc-expand): Removed hook setup.
 351         (syncase): Publish syntax transformer to be used with
 352         `use-syntax'.
 353         (sc-macro): Use this as the value when publishing macros.
 354
 355         * boot-9.scm (module-type): Added `transformer'.
 356         (make-module): Modified initialization.
 357         (module-transformer, set-module-transformer!): Selector and
 358         mutator for module-associated transformer.
 359         (set-current-module): Use module-transformer to set
 360         `scm:eval-transformer'.
 361         (module-use!): Previous change reverted.
 362 *       (use-syntax): New function: Install a transformer in current
 363         module.
 364         (sc-interface, sc-expand): Removed! :)
 365
 366 Fri Sep  5 03:09:09 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 367
 368         * emacs.scm (emacs-load): Added new parameter `module'.
 369
 370         * syncase.scm (putprop, getprop): Modified to use the object
 371         properties of the variable object corresponding to the symbol;
 372         This way we can ride on the mechanisms of the module system.
 373         Changed `builtin-variable' calls to `define-public' calls.
 374         Setup the hooks sc-expand and sc-interface.
 375
 376         * boot-9.scm (sc-interface, sc-expand): New builtin variables.
 377         (set-current-module): Switch to and from sc-expand as
 378         scm:eval-transformer when going into and out of modules using
 379         syncase macros.
 380         (module-use!): Set scm:eval-transformer to sc-expand when adding
 381         the syncase interface.
 382
 383 Thu Sep  4 14:57:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 384
 385         * syncase.scm (putprop): Temporary fix which publishes new syntax
 386         globally (the old behaviour was complex and connected to the inner
 387         workings of the current module system).
 388
 389 Wed Sep  3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 390
 391         * psyntax.ss: Updated.
 392         psyntax.pp: Bugfix: Previous version had some leading "t":s cut
 393         off!
 394
 395 Tue Sep  2 00:26:42 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 396
 397         * boot-9.scm (gensym): Removed (replaced by primitive).
 398         (obarray-gensym): Rewritten to use `gensym'.
 399         (gentemp): Rewritten to use `gensym'.
 400
 401 Mon Sep  1 20:08:32 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 402
 403         * gtcl.scm (make-tcl-binder): Rewritten to choose bindings
 404         according to the following priorities:
 405         1. tcl bindings which are present in override-scheme-list
 406         2. bindings from the-scm-module
 407         3. tcl bindings
 408         This way the gtcl module can occur first in the use-list without
 409         disabling the scheme interpreter.
 410         (new-interpreter): New function.
 411
 412         * gwish.scm: Moved initialization code for the-interpreter to
 413         gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
 414         it; Call `new-interpreter'; Don't :use-module (guile).
 415
 416 Thu Aug 28 23:48:53 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 417
 418         * Makefile.in: Regenerated.
 419
 420 Wed Aug 27 11:35:09 1997  Jim Blandy  <jimb@totoro.red-bean.com>
 421
 422         * Makefile.in: Regenerated, so it uses "tar", not "gtar".
 423
 424 Mon Aug 25 22:00:44 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 425
 426         * emacs.scm (object->string, format, error-args->string): New
 427         procedures.
 428         (emacs-frame-eval): Reworked.
 429
 430 Mon Aug 25 16:15:55 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 431
 432         * session.scm (apropos-internal): Musn't initialize symbol
 433         accumulator with a constant pair.  That led to mutation of the
 434         source!
 435
 436 Sun Aug 24 01:03:10 1997  Mikael Djurfeldt  <mdj@kenneth>
 437
 438         * session.scm (vector-for-each): Removed.
 439         (apropos): vector-for-each --> array-for-each.
 440         (apropos-internal): New function.  Return list of accessible
 441         symbols matching regexp.
 442
 443         * debug.scm (frame-number->index): New function.  Convert frame
 444         number (as displayed in the backtrace) to frame index (to be used
 445         in stack-ref).
 446
 447         * emacs.scm (emacs-load): New arguments: interactivep: when
 448         non-false, send back results to Emacs; colnum: Column number;
 449         Use modules (ice-9 debug) and (ice-9 session);
 450         (no-stack, no-source): New simple-actions;
 451         (result-to-emacs): New procedure. Sends data to Emacs via the
 452         result protocol;
 453         (get-frame-source, emacs-select-frame, emacs-frame-eval,
 454         emacs-symdoc): New procedures.
 455
 456 Wed Aug 20 13:21:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 457
 458         * emacs.scm (emacs-load): Adjust stack narrowing.
 459         (whitespace-chars): Include #\np.
 460
 461         * syncase.scm: Also turn off debugging evaluator and recording of
 462         procedure names during loading of psyntax.pp.
 463
 464         * psyntax.pp: Removed leading blanks => 800K -> 100K.
 465
 466 Tue Aug 19 02:39:41 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 467
 468         * syncase.scm: Don't tamper with debug mode setting when enabling
 469         macros.  Instead cut the stack with start-stack.
 470         Load psyntax.pp with recording of positions turned off.
 471
 472         * psyntax.pp, psyntax.ss (quasiquote): Changed fx= --> =.
 473
 474 *       * syncase.scm: New file: Guile-adaption for syntax-case macros.
 475         psyntax.pp, psyntax.ss: Syntax-case macros, portable version 2 by
 476         R. Kent Dybvig, Oscar Waddell, Bob Hieb and Carl Bruggeman
 477
 478 Mon Aug 18 21:58:25 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 479
 480 *       * session.scm: New file: Session support.
 481         (apropos): New procedure: List bindings given regexp.
 482
 483 Sat Aug 16 18:44:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 484
 485         * boot-9.scm: define tms accessors: clock, utime, stime, cutime,
 486         cstime.
 487
 488 Thu Aug 14 19:55:37 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 489
 490         * emacs.scm (emacs-load): Something has changed in the reader so
 491         that we now should set the port line count to the specified value
 492         (linum) instead of (- linum 1).
 493
 494         * slib.scm (slib:load): Use load-from-path instead of
 495         primitive-load-path so that backtraces get narrowed properly at
 496         the top.
 497
 498         * boot-9.scm (top-repl): Save stack already in signal handler in
 499         order to narrow it correctly.
 500         (save-stack): Adjust narrowing tag for the top of load-stacks.
 501
 502 Tue Jul 29 01:18:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
 503
 504         * boot-9.scm (move->fdes, dup->port): use dup->fdes, not primitive-dup.
 505         (dup->fdes): deleted, now done in C.
 506
 507 Sat Jul 26 08:00:42 1997  Gary Houston  <ghouston@actrix.gen.nz>
 508
 509         * boot-9.scm (setenv): new procedure, scsh compatible.
 510
 511 Sat Jul 26 21:30:10 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 512
 513         * boot-9.scm (with-fluids): New macro to go with the
 514         builtin `with-fluids*'.
 515
 516 Thu Jul 24 04:28:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 517
 518         * slib.scm (install-require-module): In newer versions of slib
 519         *catalog* is #f until the first access.  Therefore we call
 520         require:provided? for a random feature if *catalog* is #f.
 521
 522 Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 523
 524         * boot-9.scm: If using emacs interface, enable backtraces
 525         automatically.
 526
 527 Mon Jul 21 06:45:45 1997  Gary Houston  <ghouston@actrix.gen.nz>
 528
 529         * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
 530         dup, fdes->inport, fdes->outport, port->fdes): new procedures.
 531         (duplicate-port): was a C primitive, now it's here.
 532         (move->fdes): allow the first argument to be a file descriptor.
 533         Return the modified port or file descriptor (was unspecified.)
 534
 535 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
 536
 537         Changes to compile under gnu-win32, from Marcus Daniels:
 538         * boot-9.scm (load-user-init): If HOME is unset, provide
 539         a default of /.
 540
 541         * boot-9.scm (define-public): Changed to accomodate Hobbit.
 542
 543 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
 544
 545         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
 546         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
 547         notation, instead of #/ notation.
 548
 549         * expect.scm (expect-strings): Pass regexp/newline flag to
 550         make-regexp.
 551
 552 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
 553
 554         Fix inconsistencies in parsing of #/ style lists.
 555         * boot-9.scm (read-path-list-notation): New function.
 556         (parse-path-symbol): Deleted.  Replaced by above.
 557         Plug in read-path-list-notation as the parser for #/ lists,
 558         instead of the anonymous lambda form calling parse-path-symbol.
 559         (Thanks to Maurizio Vitale.)
 560
 561         * boot-9.scm (make-list): Remove the definition of this function
 562         from the (ice-9 common-list) module; make the `init' argument
 563         optional in the scm module's definition, to match the deleted
 564         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
 565
 566 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
 567
 568         Try to detect when people are using one version of libguile and a
 569         different version of ice-9.  People have been skewing things and
 570         sending in bug reports.
 571         * version.scm.in: New file, which the configure script munges to
 572         produce version.scm, which contains the ice-9 config stamp.
 573         * boot-9.scm: Compare the libguile and ice-9 config stamps;
 574         display a warning if the two are different.
 575         * Makefile.am: Install version.scm, but don't distribute it.
 576         Distribute version.scm.in, but don't install it.
 577         * Makefile.in: Regenerated.
 578
 579 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
 580
 581         * slib.scm (slib:warn): Alias for WARN function.
 582
 583 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
 584
 585         * boot-9.scm (struct-printer): Fix off-by-one error in range
 586         check.  Correctly check for struct printer tag.
 587
 588         * expect.scm: Turn this into a module, (ice-9 expect).
 589         (expect-port, expect-timeout, expect-timeout-proc,
 590         expect-eof-proc, expect-char-proc, expect, expect-strings,
 591         expect-select): Make these public definitions.
 592         (expect-strings): Use make-regexp and regexp-exec, instead of
 593         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
 594         that's okay.
 595
 596         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
 597         users in the core, and relies on mildly hairy details of the old
 598         regexp interface.
 599
 600         * test.scm: Re-enable tests asserting that '() is true, and not a
 601         boolean.  This stuff has been true for a while.
 602
 603         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
 604         function names.
 605
 606         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
 607         fixes.
 608
 609 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
 610
 611         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
 612         ../configure.in.
 613
 614 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 615
 616         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
 617         vtable and not the one of the struct.
 618
 619 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 620
 621         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
 622         make-struct-printer, set-struct-printer-in-vtable!): New bindings
 623         to support printing of structures.
 624         (record-type-vtable, make-record-type): Add slot to hold printing
 625         function and initialize it with something appropriate.  Removed
 626         commented out printing code.
 627         (record-type-name, record-type-fields): Adjusted slot offsets.
 628         (%print-module): Reduce argument list to "mod" and "port".
 629
 630 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
 631
 632         * slib.scm (identity): New function, used by SLIB.
 633
 634 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
 635
 636         * boot-9.scm: signal-handler, alarm-thunk: removed.
 637         don't define ticks-interrupt etc.
 638         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
 639         during call to scm-style-repl.
 640
 641 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
 642
 643         * slib.scm (slib:load): Use primitive-load-path instead of
 644         basic-load.  This is probably wrong, but hopefully the entire
 645         source access system will be revised soon anyway, and this will
 646         make require behave more like Emacs Lisp's require.  If this
 647         breaks something, please let me know.  Maybe this is real dumb.
 648
 649 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
 650
 651         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
 652         * boot-9.scm: If the `regex' feature is present, use the module
 653         (ice-9 regex).
 654
 655 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
 656
 657         * regex.scm: New file.
 658         * Makefile.am (subpkgdata_DATA): Add regex.scm.
 659         * Makefile.in: Regenerated.
 660
 661 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
 662
 663         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
 664         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
 665         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
 666         threads.scm: New address for FSF.
 667
 668 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
 669
 670         * debug.scm: Update copyright years; this file has been worked on
 671         in 1997.
 672
 673 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
 674
 675         * expect.scm: use gettimeofday instead of get-internal-real-time
 676         and use a floating point timeout when calling select.  Untested,
 677         since the regex library is currently AWOL.
 678
 679 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
 680
 681         * boot-9.scm (eval-string): Function deleted; it was already
 682         implemented in C, so there's no point in making a divergable copy
 683         here.
 684
 685 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 686
 687         * Makefile.in: Regenerated, using automake-1.1p.
 688
 689 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 690
 691         * Makefile.in: Regenerated, using automake-1.1p.
 692
 693 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 694
 695         * boot-9.scm (error-catching-loop): don't read a line from
 696         current input when quit is encountered, the previous change
 697         fixes this too.
 698
 699 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
 700
 701         * boot-9.scm (scm-style-repl): After reading an expression,
 702         consume any trailing newline (perhaps preceded by whitespace), to
 703         avoid screwing up GDB.  More detail in comments.
 704
 705 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
 706
 707         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
 708         the Scheme code like code yet.
 709         * Makefile.in: Resrac,husrched.
 710
 711 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 712
 713         * boot-9.scm (link-dynamic-module): Do not catch errors from
 714         dynamic-link and dynamic-call.  When the shared library exists it
 715         is now assumed to be suitable for a dynamic C module.
 716
 717 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 718
 719         * boot-9.scm (process-use-modules): New function to support the
 720         use-modules macro
 721         (use-modules): throw an error iff one of the requested modules
 722         can't be found.
 723
 724 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 725
 726         * boot-9.scm: don't define timer-thunk or gc-thunk.
 727
 728 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 729
 730         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 731
 732         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 733         we're not using AM_INIT_GUILE_MODULE any more.
 734         * Makefile.in: Regeneratitetedrerd.
 735
 736 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 737
 738         Get 'make dist' to work again.
 739         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 740         * Makefile.in: Regenerated, like two tons of fleas.
 741
 742         Changes for reduced Guile distribution: one configure script,
 743         no plugins.
 744         * configure.in, configure: Removed.
 745         * Makefile.in: Regenerated.
 746
 747 Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>
 748
 749         * boot-9.scm (eval-string, command-line, load-user-init): New
 750         functions.
 751
 752 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 753
 754         * boot-9.scm (log10): defined.
 755
 756 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 757
 758         * expect.scm (expect-select): correct the millisecond timeout
 759         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 760
 761 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 762
 763         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 764         instead of in libguile.
 765         (tm:sec etc.) new accessors for broken-down time.
 766         (set-tm:sec etc.) new setters for broken-down time.
 767
 768 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 769
 770         * boot-9.scm (netent:addrtype, servent:port): added missing
 771         procedures.
 772         (netent:net, servent:proto): repaired.
 773         (utsname:sysname etc.): new accessors for uname.
 774
 775 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 776
 777         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 778         sockaddr:port): new functions.
 779
 780 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 781
 782         * boot-9.scm: define accessor procedures for the objects returned
 783         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 784         passwd:name, where the first component is the name of the C structure
 785         and the second is the unprefixed C member name.)
 786
 787 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 788
 789         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 790         setservent): no longer take an argument, it was bogus.
 791
 792 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 793
 794         * boot-9.scm (scm-error): deleted, reimplemented in C.
 795
 796 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 797
 798         * boot-9.scm (process-define-module): Modified to handle both
 799         keywords and symbols.
 800
 801 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 802
 803         * slib.scm: update read usage.
 804
 805         * r4rs.scm: update primitive-load usage.
 806         Don't define read-sharp.
 807
 808         * boot-9.scm: use read-hash-extend to install extra read syntax.
 809         (read-sharp): removed.
 810         Adjust usage of primitive-load-path, read, which no longer take
 811         case_i or read-sharp arguments.
 812
 813 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 814
 815         * boot-9.scm: Added loading of session support module.
 816
 817         * debug.scm: Removed `display-application'.  (Replaced by
 818         primitive procedure.)
 819
 820         * boot-9.scm (beautify-user-module!): Don't add the root module
 821         interface to the end of the use-list of the root module.
 822
 823 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 824
 825         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 826
 827 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 828
 829         * boot-9.scm: check use-emacs-interface for emacs support.
 830
 831 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 832
 833         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 834         read gets EOF.
 835         * (exit): alias for quit.
 836
 837 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 838
 839         * boot-9.scm (error-catching-loop thunk): use a status variable to
 840         return the quit args.
 841         (scm-style-repl): call -quit, passing return value from
 842         error-catching-repl.  Make -quit return its args.
 843         stand-alone-repl: comment out, since it seems unused.
 844
 845         (error-catching-loop thunk): discard trailing junk after a (quit).
 846
 847 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 848
 849         * boot-9.scm: Removed the old printer code.
 850
 851         * r4rs.scm (apply, call-with-current-continuation): Added comment
 852         explaining why apply and call/cc need to be closures.
 853
 854         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 855         Removed. These definitions are already present in r4rs.scm.
 856
 857         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 858         stack before printing traced frames; Re-enable trace flag at end
 859         of handlers.
 860
 861 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 862
 863         * debug.scm: Add hook for reset of trace level at abort.
 864
 865         * boot-9.scm (run-hooks): New procedure.
 866         (add-hooks!): New macro.
 867         Change hooks to use these functions.
 868
 869         * debug.scm: *Warning* This feature is a bit premature.  I add
 870         it anyway because 1. it is very useful, and, 2. you can start
 871         making it less premature by complaining to me and by modifying
 872         the source! :-)
 873         (trace): Given one or more procedure objects, trace each one.
 874         Given no arguments, show all traced procedures.
 875         (untrace): Given one or more procedure objects, untrace each one.
 876         Given no arguments, untrace all traced procedures.  The tracing in
 877         Guile have an advantage to most other systems: We don't create new
 878         procedure objects, but mark the procedure objects themselves.
 879         This means that also anonymous and internal procedures can be
 880         traced.
 881
 882         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 883         and exit-frame exceptions.
 884
 885         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 886         (set-repl-prompt!): Setter for repl prompt.
 887         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 888         string, display it; if prompt is a thunk, call it and display its
 889         result; otherwise display "> ".
 890         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 891
 892         * r4rs.scm (%load-verbosely): Reverted change to
 893         `module-defined?', since the module system isn't bootstrapped when
 894         we load r4rs.scm.  This is just a temporary fix to make the
 895         repository version runnable.
 896
 897 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 898
 899         * boot-9.scm: Removed the enabling of debug evaluator and
 900         recording of source code positions.  This was placed there for our
 901         convenience, but it has already sneaked into the distribution
 902         once... so we'd better add this in our local copies instead when
 903         we need it.  (These options are normally enabled at the end of
 904         boot-9.scm when loading the debug module.)
 905
 906 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 907
 908         * boot-9.scm (module-defined?): New function.
 909         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 910         and eval.
 911         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 912         "defined?".
 913         * slib.scm (defined?): New function to take the place of the
 914         builtin "defined?".  It allways examines the slib module.
 915
 916 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 917
 918         * configure.in: Added AM_MAINTAINER_MODE
 919
 920 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 921
 922         * boot-9.scm (read-sharp): define directly, don't go through a
 923         %read-sharp layer.
 924
 925 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 926
 927         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 928         uniform-vector-set1! which doesn't exist.
 929
 930 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 931
 932         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 933         backtrace.c.)
 934
 935 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 936
 937         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 938         read-line): new procedures, see libguile/ChangeLog.
 939
 940 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 941
 942         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 943
 944         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 945         init-dynamic-module, dynamic-maybe-call,
 946         find-and-link-dynamic-module, link-dynamic-module,
 947         try-module-dynamic-link, registered-modules): New definitions for
 948         dynamic linking of modules.
 949         (resolve-module): Try to dynamically link the requested module
 950         after failing to load it as Scheme code.
 951
 952 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 953
 954         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 955
 956 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 957
 958         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 959         that's what it is.
 960
 961         * lineio.scm (make-line-buffering-input-port): Properly test for
 962         the case of an empty buffer list.  The old code assumed that '()
 963         was false.
 964
 965 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 966
 967         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 968         (use-modules <module name> ...) Put the the modules named by
 969         <module name> ... on the use list of the current module.
 970
 971 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 972
 973         * boot-9.scm (error-catching-loop): Remove message saying that
 974         typing "$" will put you in the debugger.  This isn't implemented
 975         yet.
 976
 977 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 978
 979         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 980         been fixed, so this function is superfluous.
 981         (transform-usage-lambda): Use delq!, not delq-all!.
 982
 983 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 984
 985         * boot-9.scm (resolve-module): New optional parameter that
 986         controls whether autoloading is attempted or not. Default is #t.
 987         (process-define-module): Don't autoload the defined module.
 988         (try-module-autoload): Don't autoload the directory modules.
 989
 990         * boot-9.scm (process-define-module): Ensure that the-scm-module
 991         is last in the `uses' list to allow shadowing builtin
 992         bindings. All :use-module options are added in the order they
 993         appear in the arguments but before anything already on the list
 994         (such as the-scm-module).
 995
 996 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 997
 998         * slib.scm (slib-parent-dir): throw error if #f returned from
 999         %search-load-path.
1000
1001 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
1002
1003         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
1004         * Makefile.am, aclocal.m4: New files.
1005         * configure.in: Updated for Automake.
1006
1007 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
1008
1009         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
1010         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
1011         function, use it accordingly.
1012
1013 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
1014
1015         It's an "eval closure", not an "eval thunk."  A thunk is a
1016         function of no arguments.
1017         * boot-9.scm (module-type): Rename module field.
1018         (make-module, eval-in-module, make-root-module,
1019         set-current-module): Uses changed.
1020         (module-eval-closure, set-module-eval-closure!,
1021         root-module-closure): Renamed from module-eval-thunk,
1022         set-module-eval-thunk!, root-module-thunk.
1023         (set-current-module): Change uses of *top-level-lookup-thunk* to
1024         *top-level-eval-closure*.
1025
1026 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1027
1028         * slib.scm (slib-parent-dir): Use string-length, not length.
1029         (Thanks to Bernard Urban.)
1030
1031 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1032
1033         * boot-9.scm: The debugging evaluator and recording of positions
1034         aren't enabled by default any longer (they are switched on in
1035         debug.scm).  But during development we want to have them also
1036         *inside* boot-9.scm.  Therefore, two lines are added at the
1037         beginning of boot-9.scm to enable these.
1038
1039         Call `provide' so that `records' are included among the
1040         `*features*'.
1041
1042         The scheme for saving the stack has been adjusted: save-stack is
1043         now commonly available for saving the stack.  Calling `save-stack'
1044         sets a flag `stack-saved?' which prevents overwriting the stack.
1045         `stack-saved?' is reset at `abort'.
1046
1047         Spelling correction: seperate --> separate.
1048
1049         Removed `:'s that had creeped into some comments.
1050
1051         The repl now doesn't print #<unspecified> results any longer
1052         If the user wants to see this, he can do
1053         (assert-repl-print-unspecified #t) in his startup file.
1054
1055         The user now gets a friendly message instead of a backtrace at
1056         error.
1057
1058         Added `before-read-hook'.
1059
1060         Load module (ice-9 emacs) if option `-e' was specified.
1061
1062         (provide): New function.
1063
1064         (error): Save stack at entry, so that Guile entrails won't show up
1065         in backtraces.
1066
1067         (backtrace): New function.
1068
1069         (save-stack): Can now take arbitrary number of stack narrowing
1070         specifier pairs.  The first specifier in a pair controls inner
1071         border, the second the outer border.  A number means cut that
1072         number of frames, a procedure object means cut until that object
1073         is found in operator position in a frame.
1074
1075         * debug.scm: Enable debugging evaluator and recording of positions
1076         by default.
1077
1078         * slib.scm (slib:load): Adapt to the new behavior of
1079         primitive-load: It doesn't any longer try both with and without
1080         ".scm" extension.  (We don't want to use %search-load-path here.)
1081
1082         (implementation-vicinity): New function.  slib requires it
1083
1084         (library-vicinity): Updated.
1085
1086         Load "require.scm" in the library-vicinity.
1087
1088         (install-require-vicinity, install-require-module): New functions.
1089
1090 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
1091
1092         * boot-9.scm (load-from-path): New function.
1093
1094         * boot-9.scm (try-load, basic-try-load, try-load-module,
1095         try-load): Deleted.  I don't think they're being used.
1096
1097         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
1098         so they'll get distributed.
1099
1100         Get Guile to be a little less chatty by default.  The new user
1101         should see as little clutter as possible.
1102         * r4rs.scm (%load-verbosely): Make this #f by default.
1103         * boot-9.scm (scm-repl-verbose): Make this #f by default.
1104         (scm-style-repl): Don't run 'pk' on the value passed to quit.
1105
1106         * r4rs.scm: New file.
1107         * boot-9.scm: Load r4rs.scm, first thing.
1108         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
1109         open-output-file, open-io-file, close-input-port,
1110         close-output-port, close-io-port, call-with-input-file,
1111         call-with-output-file, with-input-from-port, with-output-to-port,
1112         with-error-to-port, with-input-from-file, with-output-to-file,
1113         with-error-to-file, with-input-from-string, with-output-to-string,
1114         with-error-to-string, the-eof-object): Definitions moved to
1115         r4rs.scm.  Not all of them are R4RS, but those that are use those
1116         that are not.
1117         (load, %load-verbosely, %load-announce): Moved, along with code to
1118         set %load-hook, to r4rs.scm.
1119
1120         * test.scm: New file.
1121
1122         * boot-9.scm (integer?): Definition deleted, in favor of the one
1123         present in libguile (which used to be called int?).  I have no
1124         idea why integer? didn't just call int? to begin with.
1125
1126         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
1127         =?, >?, and >=? deleted; they're defined that way by libguile now.
1128
1129         * boot-9.scm (load): Simplified; primitive-load does most of this
1130         work now.
1131         (%load-announce-win): Removed; no longer used.  Set %load-hook to
1132         call %load-announce.
1133
1134 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
1135
1136         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
1137         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
1138         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
1139         components.
1140         (file-is-directory?): use stat:type.
1141
1142 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
1143
1144         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
1145         that's now taken care of in libguile, and in a way compatible with
1146         SCSH (which this isn't).
1147
1148 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1149
1150         * boot-9.scm: Formatting tweaks.
1151
1152 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
1153
1154         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
1155         after-error-hook, before-backtrace-hook and after-backtrace-hook
1156         to the error handler.  E.g.: fancy emacs support could plug into
1157         these.
1158         (save-stack): New function.  The stack is now made differently
1159         depending on the stack id.  (The motivation is to make a better
1160         choice regarding what stack frames to present to the user.)
1161         (error-catching-loop): Stack handling code moved outside into
1162         save-stack.
1163
1164 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
1165
1166         * Makefile.in (scm_files): add expect.scm.
1167
1168         * expect.scm: new file ported from guile-iii.
1169
1170         * boot-9.scm: remove handle-system-error, after moving the code into
1171         error-catching-loop.
1172         Don't set 'throw-handler-default property on error keys.
1173         Just interpret (almost) any throw with 4 args as an error throw.
1174         Delete some try-load stuff that was already commented out.
1175
1176         Second thoughts, keep handle-system-error but call it from
1177         error-catching-loop.
1178
1179 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
1180
1181         * boot-9.scm: Doc fixes.
1182         (make-module): Rework for readability.
1183         (make-root-module, make-scm-module): USES argument to make-module
1184         should be '(), not #f.
1185
1186         * boot-9.scm (try-load): %sys-load-path has been renamed to
1187         primitive-load-path; adjust call here.
1188
1189 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1190
1191         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
1192         the stack to the correct place: when it is decided to generate an
1193         error-signal.
1194
1195 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1196
1197         * boot-9.scm (error-catching-loop, signal-handler,
1198         handle-system-error): Backtracing now works for signals aswell;
1199         Backtracing mechanism can now identify the stack root created by
1200         start-stack so that the user isn't exposed to system stack frames.
1201
1202 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1203
1204         * Makefile.in: Added threads.scm.
1205
1206 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1207
1208         * debug.scm (make-enable, make-disable): Simplified.
1209
1210         * boot-9.scm: Renamed %%throw-handler-default -->
1211         throw-handler-default.
1212         ((handle-system-error key . arg-list)): Changed the way errors are
1213         reported.
1214         ((scm-style-repl)): Wrap up the call to eval in a start-stack
1215         acro.
1216         ((error-catching-loop thunk)): Introduce a lazy-catch into
1217         error-catching-loop so that the stack can be captured.
1218
1219 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1220
1221         * mapping.scm (hash-table-mapping): Explicitly request that
1222         make-vector fill new vectors with '(); this will make it easier to
1223         port Guile Scheme code to other Schemes.
1224         * boot-9.scm (make-print-style, make-print-table): Same.
1225
1226 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
1227
1228         * boot-9.scm (load): rewritten again.
1229         Append "." to the default %load-path.
1230         (feature?): new function: checks for a symbol in the features list.
1231         (module-local-variable): remove apparently useless (caddr (list m v
1232         ...))
1233         (%load-announce): minor formatting change.
1234         (file-exists?): use access? if posix is featured.
1235         (file-is-directory?): use stat if i/o-extensions is featured.
1236         (try-module-autoload module-name): use file-exists? before
1237         file-is-directory?
1238
1239 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
1240
1241         * boot-9.scm: Added conditional loading of threads.scm.
1242
1243         * threads.scm: New file.  Modified from the Cygnus-r0.3
1244         distribution.
1245
1246         * boot-9.scm (error-catching-loop): Added handling of key
1247         `switch-repl'.
1248
1249         * boot-9.scm: Name change %%bad-throw --> bad-throw.
1250
1251 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1252
1253         * boot-9.scm (make-record-type, record-constructor): Don't assume
1254         the empty list is false when parsing the argument list.
1255
1256 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1257
1258         * boot-9.scm (signal-handler): Clean up logic.
1259
1260         * boot-9.scm (load): Assume %load-path is always bound.
1261
1262 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
1263
1264         * boot-9.scm (error): replace another throw with scm-error.  Throw
1265         to 'misc-error instead of 'error (no need to distinguish these.)
1266         Don't set up 'error as a key.
1267         Set up regex-error as a key, if regex is available.
1268         (signal-handler): use scm-error, not throw.
1269
1270         (%try-load, try-load-with-path, %load, load-with-path,
1271         basic-try-load-with-path, basic-load-with-path,
1272         try-load-module-with-path,load-module-with-path): deleted, since
1273         they seem redundant.
1274         (try-load): define using %try-load, not try-load-with-path.
1275         (load): rewritten.  load tries to open the file directly and
1276         with a .scm extension before searching the library directories
1277         (should "." be added to %load-path?  then load could still open
1278         directly files starting with "/").
1279         (try-module-autoload): use load, not load-with-path.
1280         (%load-indent): deleted, -2 was causing errors.
1281
1282         (%read-sharp): use port-line, not line-number.
1283
1284 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1285
1286         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
1287         straightforward to provide the equivalent functionality using
1288         (catch #t ...), so there's no need for the extra complexity.  2)
1289         Outside the context of a read-eval-print loop (which Guile should
1290         not require) it's not clear we should do anything more complicated
1291         than print an error and exit; the user or REPL can establish
1292         something better if it wants.  3) In that case, it's much more
1293         robust to just do it in the C code.
1294
1295 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
1296
1297         * boot-9.scm (%try-load): define using primitive-load.  Previously
1298         %try-load itself was the primitive.
1299         (load-with-path): use scm-error instead of %load-announce-lossage.
1300         Errors are thrown to 'misc-error instead of 'could-not-load.
1301         (%load-announce-lossage): deleted.
1302
1303 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
1304
1305         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
1306         (make-record-type type-name fields): Temporarily remove support
1307         for printing of records (not possible yet with C printer).
1308
1309 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
1310
1311         * boot-9.scm (file-exists?, file-is-directory): catch only
1312         system-error, not every kind of error.
1313         (scm-error): new procedure.
1314
1315 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
1316
1317         * boot-9.scm: Formatting tweaks.
1318
1319 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
1320
1321         * boot-9.scm (%%handle-system-error key): remove the code for
1322         SCM-style errors.  handle the case that an unexpected number
1323         of args are supplied.
1324         (%%system-errors): removed.
1325         (error): redefine using a throw with key and 4 args.
1326         ('error): associate 'error, 'error-signal keys with
1327         %%handle-system-error.
1328         (%%default-error-handler): removed.
1329         (signal-handler): throw with 4 args and use the error-signal key.
1330         Create an error message instead of using numerical codes.
1331         (%%bad-throw): call error instead of throw if key not found.
1332
1333 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
1334
1335         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
1336         (%%handle-system-error key): check subr is not #f before printing.
1337         Recognize %s (embed an argument using "display") and
1338         %S (embed an argument using "write").
1339
1340 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
1341
1342         * boot-9.scm (%%handle-system-error key): set args and rest to
1343         the empty list if they are #f.
1344         Initialize out-of-range as an error key.
1345
1346 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
1347
1348         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
1349
1350         * boot-9.scm: remove leading %% from references to '%%system-error.
1351         (%%handle-system-error): don't pass all the thrown arguments when
1352         aborting, just the key and subr.
1353         Remove the code to "Install default handlers for built-in errors."
1354         Remove the definition of the syserror procedure.
1355         Associate 'numerical-overflow with default handler.
1356
1357 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1358
1359         * boot-9.scm: Name change: value-ref --> local-ref
1360         resolved-ref --> nested-ref  Motivation: conformance to the other
1361         dictionary operators: list-ref operates on list, vector-ref
1362         operates on vector, nested-ref operates on nested namespace,
1363         local-ref operates on the local nested namespace.
1364
1365 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
1366
1367         * boot-9.scm (%%handle-system-error): recognise errors thrown
1368         by lgh-error (fill-message etc.)
1369         (fill-message): check first whether args is null.
1370         (fill-message): bug fix and check that args is a list.
1371
1372 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
1373
1374         * boot-9.scm: %load-path is initialized in C code now.
1375         (implementation-vicinity, parse-path): Deleted, along with code to
1376         initialize %load-path.
1377
1378         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
1379         "/", use one to separate it from the file.
1380
1381 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
1382
1383         * boot-9.scm (%load-path): Add the site directory.
1384         Add the directory named after the version number.
1385         Prepend the version number to the other directories in the path.
1386         Simplify by mapping the common prefix onto each item.
1387         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
1388         sitedatadir): New definitions.
1389         (libparent, libdir, install_path): Replaced by above.
1390         (install): Create the above directories.
1391         Put the source files into subpkgdatadir.
1392         (uninstall): Remove the above directories.
1393
1394 Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
1395
1396         Don't use the PLUGIN system to gather information for the
1397         Makefile's distribution and installation targets; just put it all
1398         in the Makefile directly.
1399         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
1400         for these.
1401         * configure.in: Remove code that gets and substitutes scm_files and
1402         aux_files.
1403         * Makefile.in (scm_files, aux_files): Write out the list of files
1404         here, where people expect to find them.

1407
1408         * boot-9.scm: Preliminary solution: optionally load the debug
1409         module.  Changed "gls" to "guile1.0b3".
1410
1411         * debug.scm: New file: debug extensions.
1412
1413 Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
1414
1415         * boot-9.scm (print-vector): Renamed weak-hash-table? -->
