ice-9/ChangeLog

   1 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
   2
   3         Try to detect when people are using one version of libguile and a
   4         different version of ice-9.  People have been skewing things and
   5         sending in bug reports.
   6         * version.scm.in: New file, which the configure script munges to
   7         produce version.scm, which contains the ice-9 config stamp.
   8         * boot-9.scm: Compare the libguile and ice-9 config stamps;
   9         display a warning if the two are different.
  10         * Makefile.am: Install version.scm, but don't distribute it.
  11         Distribute version.scm.in, but don't install it.
  12         * Makefile.in: Regenerated.
  13
  14 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
  15
  16         * slib.scm (slib:warn): Alias for WARN function.
  17
  18 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
  19
  20         * boot-9.scm (struct-printer): Fix off-by-one error in range
  21         check.  Correctly check for struct printer tag.
  22
  23         * expect.scm: Turn this into a module, (ice-9 expect).
  24         (expect-port, expect-timeout, expect-timeout-proc,
  25         expect-eof-proc, expect-char-proc, expect, expect-strings,
  26         expect-select): Make these public definitions.
  27         (expect-strings): Use make-regexp and regexp-exec, instead of
  28         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
  29         that's okay.
  30
  31         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
  32         users in the core, and relies on mildly hairy details of the old
  33         regexp interface.
  34
  35         * test.scm: Re-enable tests asserting that '() is true, and not a
  36         boolean.  This stuff has been true for a while.
  37
  38         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
  39         function names.
  40
  41         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
  42         fixes.
  43
  44 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
  45
  46         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
  47         ../configure.in.
  48
  49 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  50
  51         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
  52         vtable and not the one of the struct.
  53
  54 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  55
  56         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
  57         make-struct-printer, set-struct-printer-in-vtable!): New bindings
  58         to support printing of structures.
  59         (record-type-vtable, make-record-type): Add slot to hold printing
  60         function and initialize it with something appropriate.  Removed
  61         commented out printing code.
  62         (record-type-name, record-type-fields): Adjusted slot offsets.
  63         (%print-module): Reduce argument list to "mod" and "port".
  64
  65 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  66
  67         * slib.scm (identity): New function, used by SLIB.
  68
  69 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
  70
  71         * boot-9.scm: signal-handler, alarm-thunk: removed.
  72         don't define ticks-interrupt etc.
  73         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
  74         during call to scm-style-repl.
  75
  76 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
  77
  78         * slib.scm (slib:load): Use primitive-load-path instead of
  79         basic-load.  This is probably wrong, but hopefully the entire
  80         source access system will be revised soon anyway, and this will
  81         make require behave more like Emacs Lisp's require.  If this
  82         breaks something, please let me know.  Maybe this is real dumb.
  83
  84 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
  85
  86         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
  87         * boot-9.scm: If the `regex' feature is present, use the module
  88         (ice-9 regex).
  89
  90 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
  91
  92         * regex.scm: New file.
  93         * Makefile.am (subpkgdata_DATA): Add regex.scm.
  94         * Makefile.in: Regenerated.
  95
  96 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  97
  98         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
  99         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
 100         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
 101         threads.scm: New address for FSF.
 102
 103 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
 104
 105         * debug.scm: Update copyright years; this file has been worked on
 106         in 1997.
 107
 108 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
 109
 110         * expect.scm: use gettimeofday instead of get-internal-real-time
 111         and use a floating point timeout when calling select.  Untested,
 112         since the regex library is currently AWOL.
 113
 114 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
 115
 116         * boot-9.scm (eval-string): Function deleted; it was already
 117         implemented in C, so there's no point in making a divergable copy
 118         here.
 119
 120 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 121
 122         * Makefile.in: Regenerated, using automake-1.1p.
 123
 124 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 125
 126         * Makefile.in: Regenerated, using automake-1.1p.
 127
 128 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 129
 130         * boot-9.scm (error-catching-loop): don't read a line from
 131         current input when quit is encountered, the previous change
 132         fixes this too.
 133
 134 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
 135
 136         * boot-9.scm (scm-style-repl): After reading an expression,
 137         consume any trailing newline (perhaps preceded by whitespace), to
 138         avoid screwing up GDB.  More detail in comments.
 139
 140 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
 141
 142         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
 143         the Scheme code like code yet.
 144         * Makefile.in: Resrac,husrched.
 145
 146 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 147
 148         * boot-9.scm (link-dynamic-module): Do not catch errors from
 149         dynamic-link and dynamic-call.  When the shared library exists it
 150         is now assumed to be suitable for a dynamic C module.
 151
 152 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 153
 154         * boot-9.scm (process-use-modules): New function to support the
 155         use-modules macro
 156         (use-modules): throw an error iff one of the requested modules
 157         can't be found.
 158
 159 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 160
 161         * boot-9.scm: don't define timer-thunk or gc-thunk.
 162
 163 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 164
 165         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 166
 167         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 168         we're not using AM_INIT_GUILE_MODULE any more.
 169         * Makefile.in: Regeneratitetedrerd.
 170
 171 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 172
 173         Get 'make dist' to work again.
 174         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 175         * Makefile.in: Regenerated, like two tons of fleas.
 176
 177         Changes for reduced Guile distribution: one configure script,
 178         no plugins.
 179         * configure.in, configure: Removed.
 180         * Makefile.in: Regenerated.
 181

 183
 184         * boot-9.scm (eval-string, command-line, load-user-init): New
 185         functions.
 186
 187 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 188
 189         * boot-9.scm (log10): defined.
 190
 191 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 192
 193         * expect.scm (expect-select): correct the millisecond timeout
 194         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 195
 196 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 197
 198         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 199         instead of in libguile.
 200         (tm:sec etc.) new accessors for broken-down time.
 201         (set-tm:sec etc.) new setters for broken-down time.
 202
 203 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 204
 205         * boot-9.scm (netent:addrtype, servent:port): added missing
 206         procedures.
 207         (netent:net, servent:proto): repaired.
 208         (utsname:sysname etc.): new accessors for uname.
 209
 210 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 211
 212         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 213         sockaddr:port): new functions.
 214
 215 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 216
 217         * boot-9.scm: define accessor procedures for the objects returned
 218         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 219         passwd:name, where the first component is the name of the C structure
 220         and the second is the unprefixed C member name.)
 221
 222 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 223
 224         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 225         setservent): no longer take an argument, it was bogus.
 226
 227 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 228
 229         * boot-9.scm (scm-error): deleted, reimplemented in C.
 230
 231 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 232
 233         * boot-9.scm (process-define-module): Modified to handle both
 234         keywords and symbols.
 235
 236 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 237
 238         * slib.scm: update read usage.
 239
 240         * r4rs.scm: update primitive-load usage.
 241         Don't define read-sharp.
 242
 243         * boot-9.scm: use read-hash-extend to install extra read syntax.
 244         (read-sharp): removed.
 245         Adjust usage of primitive-load-path, read, which no longer take
 246         case_i or read-sharp arguments.
 247
 248 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 249
 250         * boot-9.scm: Added loading of session support module.
 251
 252         * debug.scm: Removed `display-application'.  (Replaced by
 253         primitive procedure.)
 254
 255         * boot-9.scm (beautify-user-module!): Don't add the root module
 256         interface to the end of the use-list of the root module.
 257
 258 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 259
 260         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 261
 262 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 263
 264         * boot-9.scm: check use-emacs-interface for emacs support.
 265
 266 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 267
 268         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 269         read gets EOF.
 270         * (exit): alias for quit.
 271
 272 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 273
 274         * boot-9.scm (error-catching-loop thunk): use a status variable to
 275         return the quit args.
 276         (scm-style-repl): call -quit, passing return value from
 277         error-catching-repl.  Make -quit return its args.
 278         stand-alone-repl: comment out, since it seems unused.
 279
 280         (error-catching-loop thunk): discard trailing junk after a (quit).
 281
 282 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 283
 284         * boot-9.scm: Removed the old printer code.
 285
 286         * r4rs.scm (apply, call-with-current-continuation): Added comment
 287         explaining why apply and call/cc need to be closures.
 288
 289         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 290         Removed. These definitions are already present in r4rs.scm.
 291
 292         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 293         stack before printing traced frames; Re-enable trace flag at end
 294         of handlers.
 295
 296 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 297
 298         * debug.scm: Add hook for reset of trace level at abort.
 299
 300         * boot-9.scm (run-hooks): New procedure.
 301         (add-hooks!): New macro.
 302         Change hooks to use these functions.
 303
 304         * debug.scm: *Warning* This feature is a bit premature.  I add
 305         it anyway because 1. it is very useful, and, 2. you can start
 306         making it less premature by complaining to me and by modifying
 307         the source! :-)
 308         (trace): Given one or more procedure objects, trace each one.
 309         Given no arguments, show all traced procedures.
 310         (untrace): Given one or more procedure objects, untrace each one.
 311         Given no arguments, untrace all traced procedures.  The tracing in
 312         Guile have an advantage to most other systems: We don't create new
 313         procedure objects, but mark the procedure objects themselves.
 314         This means that also anonymous and internal procedures can be
 315         traced.
 316
 317         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 318         and exit-frame exceptions.
 319
 320         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 321         (set-repl-prompt!): Setter for repl prompt.
 322         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 323         string, display it; if prompt is a thunk, call it and display its
 324         result; otherwise display "> ".
 325         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 326
 327         * r4rs.scm (%load-verbosely): Reverted change to
 328         `module-defined?', since the module system isn't bootstrapped when
 329         we load r4rs.scm.  This is just a temporary fix to make the
 330         repository version runnable.
 331
 332 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 333
 334         * boot-9.scm: Removed the enabling of debug evaluator and
 335         recording of source code positions.  This was placed there for our
 336         convenience, but it has already sneaked into the distribution
 337         once... so we'd better add this in our local copies instead when
 338         we need it.  (These options are normally enabled at the end of
 339         boot-9.scm when loading the debug module.)
 340
 341 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 342
 343         * boot-9.scm (module-defined?): New function.
 344         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 345         and eval.
 346         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 347         "defined?".
 348         * slib.scm (defined?): New function to take the place of the
 349         builtin "defined?".  It allways examines the slib module.
 350
 351 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 352
 353         * configure.in: Added AM_MAINTAINER_MODE
 354
 355 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 356
 357         * boot-9.scm (read-sharp): define directly, don't go through a
 358         %read-sharp layer.
 359
 360 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 361
 362         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 363         uniform-vector-set1! which doesn't exist.
 364
 365 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 366
 367         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 368         backtrace.c.)
 369
 370 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 371
 372         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 373         read-line): new procedures, see libguile/ChangeLog.
 374
 375 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 376
 377         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 378
 379         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 380         init-dynamic-module, dynamic-maybe-call,
 381         find-and-link-dynamic-module, link-dynamic-module,
 382         try-module-dynamic-link, registered-modules): New definitions for
 383         dynamic linking of modules.
 384         (resolve-module): Try to dynamically link the requested module
 385         after failing to load it as Scheme code.
 386
 387 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 388
 389         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 390
 391 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 392
 393         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 394         that's what it is.
 395
 396         * lineio.scm (make-line-buffering-input-port): Properly test for
 397         the case of an empty buffer list.  The old code assumed that '()
 398         was false.
 399
 400 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 401
 402         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 403         (use-modules <module name> ...) Put the the modules named by
 404         <module name> ... on the use list of the current module.
 405
 406 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 407
 408         * boot-9.scm (error-catching-loop): Remove message saying that
 409         typing "$" will put you in the debugger.  This isn't implemented
 410         yet.
 411
 412 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 413
 414         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 415         been fixed, so this function is superfluous.
 416         (transform-usage-lambda): Use delq!, not delq-all!.
 417
 418 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 419
 420         * boot-9.scm (resolve-module): New optional parameter that
 421         controls whether autoloading is attempted or not. Default is #t.
 422         (process-define-module): Don't autoload the defined module.
 423         (try-module-autoload): Don't autoload the directory modules.
 424
 425         * boot-9.scm (process-define-module): Ensure that the-scm-module
 426         is last in the `uses' list to allow shadowing builtin
 427         bindings. All :use-module options are added in the order they
 428         appear in the arguments but before anything already on the list
 429         (such as the-scm-module).
 430
 431 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 432
 433         * slib.scm (slib-parent-dir): throw error if #f returned from
 434         %search-load-path.
 435
 436 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 437
 438         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 439         * Makefile.am, aclocal.m4: New files.
 440         * configure.in: Updated for Automake.
 441
 442 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 443
 444         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 445         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 446         function, use it accordingly.
 447
 448 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 449
 450         It's an "eval closure", not an "eval thunk."  A thunk is a
 451         function of no arguments.
 452         * boot-9.scm (module-type): Rename module field.
 453         (make-module, eval-in-module, make-root-module,
 454         set-current-module): Uses changed.
 455         (module-eval-closure, set-module-eval-closure!,
 456         root-module-closure): Renamed from module-eval-thunk,
 457         set-module-eval-thunk!, root-module-thunk.
 458         (set-current-module): Change uses of *top-level-lookup-thunk* to
 459         *top-level-eval-closure*.
 460
 461 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 462
 463         * slib.scm (slib-parent-dir): Use string-length, not length.
 464         (Thanks to Bernard Urban.)
 465
 466 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 467
 468         * boot-9.scm: The debugging evaluator and recording of positions
 469         aren't enabled by default any longer (they are switched on in
 470         debug.scm).  But during development we want to have them also
 471         *inside* boot-9.scm.  Therefore, two lines are added at the
 472         beginning of boot-9.scm to enable these.
 473
 474         Call `provide' so that `records' are included among the
 475         `*features*'.
 476
 477         The scheme for saving the stack has been adjusted: save-stack is
 478         now commonly available for saving the stack.  Calling `save-stack'
 479         sets a flag `stack-saved?' which prevents overwriting the stack.
 480         `stack-saved?' is reset at `abort'.
 481
 482         Spelling correction: seperate --> separate.
 483
 484         Removed `:'s that had creeped into some comments.
 485
 486         The repl now doesn't print #<unspecified> results any longer
 487         If the user wants to see this, he can do
 488         (assert-repl-print-unspecified #t) in his startup file.
 489
 490         The user now gets a friendly message instead of a backtrace at
 491         error.
 492
 493         Added `before-read-hook'.
 494
 495         Load module (ice-9 emacs) if option `-e' was specified.
 496
 497         (provide): New function.
 498
 499         (error): Save stack at entry, so that Guile entrails won't show up
 500         in backtraces.
 501
 502         (backtrace): New function.
 503
 504         (save-stack): Can now take arbitrary number of stack narrowing
 505         specifier pairs.  The first specifier in a pair controls inner
 506         border, the second the outer border.  A number means cut that
 507         number of frames, a procedure object means cut until that object
 508         is found in operator position in a frame.
 509
 510         * debug.scm: Enable debugging evaluator and recording of positions
 511         by default.
 512
 513         * slib.scm (slib:load): Adapt to the new behavior of
 514         primitive-load: It doesn't any longer try both with and without
 515         ".scm" extension.  (We don't want to use %search-load-path here.)
 516
 517         (implementation-vicinity): New function.  slib requires it
 518
 519         (library-vicinity): Updated.
 520
 521         Load "require.scm" in the library-vicinity.
 522
 523         (install-require-vicinity, install-require-module): New functions.
 524
 525 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 526
 527         * boot-9.scm (load-from-path): New function.
 528
 529         * boot-9.scm (try-load, basic-try-load, try-load-module,
 530         try-load): Deleted.  I don't think they're being used.
 531
 532         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 533         so they'll get distributed.
 534
 535         Get Guile to be a little less chatty by default.  The new user
 536         should see as little clutter as possible.
 537         * r4rs.scm (%load-verbosely): Make this #f by default.
 538         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 539         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 540
 541         * r4rs.scm: New file.
 542         * boot-9.scm: Load r4rs.scm, first thing.
 543         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 544         open-output-file, open-io-file, close-input-port,
 545         close-output-port, close-io-port, call-with-input-file,
 546         call-with-output-file, with-input-from-port, with-output-to-port,
 547         with-error-to-port, with-input-from-file, with-output-to-file,
 548         with-error-to-file, with-input-from-string, with-output-to-string,
 549         with-error-to-string, the-eof-object): Definitions moved to
 550         r4rs.scm.  Not all of them are R4RS, but those that are use those
 551         that are not.
 552         (load, %load-verbosely, %load-announce): Moved, along with code to
 553         set %load-hook, to r4rs.scm.
 554
 555         * test.scm: New file.
 556
 557         * boot-9.scm (integer?): Definition deleted, in favor of the one
 558         present in libguile (which used to be called int?).  I have no
 559         idea why integer? didn't just call int? to begin with.
 560
 561         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 562         =?, >?, and >=? deleted; they're defined that way by libguile now.
 563
 564         * boot-9.scm (load): Simplified; primitive-load does most of this
 565         work now.
 566         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 567         call %load-announce.
 568
 569 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 570
 571         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 572         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 573         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 574         components.
 575         (file-is-directory?): use stat:type.
 576
 577 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 578
 579         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 580         that's now taken care of in libguile, and in a way compatible with
 581         SCSH (which this isn't).
 582
 583 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 584
 585         * boot-9.scm: Formatting tweaks.
 586
 587 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 588
 589         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 590         after-error-hook, before-backtrace-hook and after-backtrace-hook
 591         to the error handler.  E.g.: fancy emacs support could plug into
 592         these.
 593         (save-stack): New function.  The stack is now made differently
 594         depending on the stack id.  (The motivation is to make a better
 595         choice regarding what stack frames to present to the user.)
 596         (error-catching-loop): Stack handling code moved outside into
 597         save-stack.
 598
 599 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 600
 601         * Makefile.in (scm_files): add expect.scm.
 602
 603         * expect.scm: new file ported from guile-iii.
 604
 605         * boot-9.scm: remove handle-system-error, after moving the code into
 606         error-catching-loop.
 607         Don't set 'throw-handler-default property on error keys.
 608         Just interpret (almost) any throw with 4 args as an error throw.
 609         Delete some try-load stuff that was already commented out.
 610
 611         Second thoughts, keep handle-system-error but call it from
 612         error-catching-loop.
 613
 614 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 615
 616         * boot-9.scm: Doc fixes.
 617         (make-module): Rework for readability.
 618         (make-root-module, make-scm-module): USES argument to make-module
 619         should be '(), not #f.
 620
 621         * boot-9.scm (try-load): %sys-load-path has been renamed to
 622         primitive-load-path; adjust call here.
 623
 624 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 625
 626         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 627         the stack to the correct place: when it is decided to generate an
 628         error-signal.
 629
 630 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 631
 632         * boot-9.scm (error-catching-loop, signal-handler,
 633         handle-system-error): Backtracing now works for signals aswell;
 634         Backtracing mechanism can now identify the stack root created by
 635         start-stack so that the user isn't exposed to system stack frames.
 636
 637 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 638
 639         * Makefile.in: Added threads.scm.
 640
 641 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 642
 643         * debug.scm (make-enable, make-disable): Simplified.
 644
 645         * boot-9.scm: Renamed %%throw-handler-default -->
 646         throw-handler-default.
 647         ((handle-system-error key . arg-list)): Changed the way errors are
 648         reported.
 649         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 650         acro.
 651         ((error-catching-loop thunk)): Introduce a lazy-catch into
 652         error-catching-loop so that the stack can be captured.
 653
 654 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 655
 656         * mapping.scm (hash-table-mapping): Explicitly request that
 657         make-vector fill new vectors with '(); this will make it easier to
 658         port Guile Scheme code to other Schemes.
 659         * boot-9.scm (make-print-style, make-print-table): Same.
 660
 661 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 662
 663         * boot-9.scm (load): rewritten again.
 664         Append "." to the default %load-path.
 665         (feature?): new function: checks for a symbol in the features list.
 666         (module-local-variable): remove apparently useless (caddr (list m v
 667         ...))
 668         (%load-announce): minor formatting change.
 669         (file-exists?): use access? if posix is featured.
 670         (file-is-directory?): use stat if i/o-extensions is featured.
 671         (try-module-autoload module-name): use file-exists? before
 672         file-is-directory?
 673
 674 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 675
 676         * boot-9.scm: Added conditional loading of threads.scm.
 677
 678         * threads.scm: New file.  Modified from the Cygnus-r0.3
 679         distribution.
 680
 681         * boot-9.scm (error-catching-loop): Added handling of key
 682         `switch-repl'.
 683
 684         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 685
 686 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 687
 688         * boot-9.scm (make-record-type, record-constructor): Don't assume
 689         the empty list is false when parsing the argument list.
 690
 691 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 692
 693         * boot-9.scm (signal-handler): Clean up logic.
 694
 695         * boot-9.scm (load): Assume %load-path is always bound.
 696
 697 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 698
 699         * boot-9.scm (error): replace another throw with scm-error.  Throw
 700         to 'misc-error instead of 'error (no need to distinguish these.)
 701         Don't set up 'error as a key.
 702         Set up regex-error as a key, if regex is available.
 703         (signal-handler): use scm-error, not throw.
 704
 705         (%try-load, try-load-with-path, %load, load-with-path,
 706         basic-try-load-with-path, basic-load-with-path,
 707         try-load-module-with-path,load-module-with-path): deleted, since
 708         they seem redundant.
 709         (try-load): define using %try-load, not try-load-with-path.
 710         (load): rewritten.  load tries to open the file directly and
 711         with a .scm extension before searching the library directories
 712         (should "." be added to %load-path?  then load could still open
 713         directly files starting with "/").
 714         (try-module-autoload): use load, not load-with-path.
 715         (%load-indent): deleted, -2 was causing errors.
 716

 720
 721         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 722         straightforward to provide the equivalent functionality using
 723         (catch #t ...), so there's no need for the extra complexity.  2)
 724         Outside the context of a read-eval-print loop (which Guile should
 725         not require) it's not clear we should do anything more complicated
 726         than print an error and exit; the user or REPL can establish
 727         something better if it wants.  3) In that case, it's much more
 728         robust to just do it in the C code.

 793
 794         * boot-9.scm: Name change: value-ref --> local-ref
 795         resolved-ref --> nested-ref  Motivation: conformance to the other
 796         dictionary operators: list-ref operates on list, vector-ref
 797         operates on vector, nested-ref operates on nested namespace,
 798         local-ref operates on the local nested namespace.

 835         for these.
