ice-9/ChangeLog

   1 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
   2
   3         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
   4         vtable and not the one of the struct.
   5
   6 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
   7
   8         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
   9         make-struct-printer, set-struct-printer-in-vtable!): New bindings
  10         to support printing of structures.
  11         (record-type-vtable, make-record-type): Add slot to hold printing
  12         function and initialize it with something appropriate.  Removed
  13         commented out printing code.
  14         (record-type-name, record-type-fields): Adjusted slot offsets.
  15         (%print-module): Reduce argument list to "mod" and "port".
  16
  17 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  18
  19         * slib.scm (identity): New function, used by SLIB.
  20
  21 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
  22
  23         * boot-9.scm: signal-handler, alarm-thunk: removed.
  24         don't define ticks-interrupt etc.
  25         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
  26         during call to scm-style-repl.
  27
  28 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
  29
  30         * slib.scm (slib:load): Use primitive-load-path instead of
  31         basic-load.  This is probably wrong, but hopefully the entire
  32         source access system will be revised soon anyway, and this will
  33         make require behave more like Emacs Lisp's require.  If this
  34         breaks something, please let me know.  Maybe this is real dumb.
  35
  36 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
  37
  38         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
  39         * boot-9.scm: If the `regex' feature is present, use the module
  40         (ice-9 regex).
  41
  42 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
  43
  44         * regex.scm: New file.
  45         * Makefile.am (subpkgdata_DATA): Add regex.scm.
  46         * Makefile.in: Regenerated.
  47
  48 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  49
  50         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
  51         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
  52         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
  53         threads.scm: New address for FSF.
  54
  55 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
  56
  57         * debug.scm: Update copyright years; this file has been worked on
  58         in 1997.
  59
  60 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
  61
  62         * expect.scm: use gettimeofday instead of get-internal-real-time
  63         and use a floating point timeout when calling select.  Untested,
  64         since the regex library is currently AWOL.
  65
  66 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
  67
  68         * boot-9.scm (eval-string): Function deleted; it was already
  69         implemented in C, so there's no point in making a divergable copy
  70         here.
  71
  72 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
  73
  74         * Makefile.in: Regenerated, using automake-1.1p.
  75
  76 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
  77
  78         * Makefile.in: Regenerated, using automake-1.1p.
  79
  80 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
  81
  82         * boot-9.scm (error-catching-loop): don't read a line from
  83         current input when quit is encountered, the previous change
  84         fixes this too.
  85
  86 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
  87
  88         * boot-9.scm (scm-style-repl): After reading an expression,
  89         consume any trailing newline (perhaps preceded by whitespace), to
  90         avoid screwing up GDB.  More detail in comments.
  91
  92 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
  93
  94         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
  95         the Scheme code like code yet.
  96         * Makefile.in: Resrac,husrched.
  97
  98 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  99
 100         * boot-9.scm (link-dynamic-module): Do not catch errors from
 101         dynamic-link and dynamic-call.  When the shared library exists it
 102         is now assumed to be suitable for a dynamic C module.
 103
 104 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 105
 106         * boot-9.scm (process-use-modules): New function to support the
 107         use-modules macro
 108         (use-modules): throw an error iff one of the requested modules
 109         can't be found.
 110
 111 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 112
 113         * boot-9.scm: don't define timer-thunk or gc-thunk.
 114
 115 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 116
 117         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 118
 119         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 120         we're not using AM_INIT_GUILE_MODULE any more.
 121         * Makefile.in: Regeneratitetedrerd.
 122
 123 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 124
 125         Get 'make dist' to work again.
 126         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 127         * Makefile.in: Regenerated, like two tons of fleas.
 128
 129         Changes for reduced Guile distribution: one configure script,
 130         no plugins.
 131         * configure.in, configure: Removed.
 132         * Makefile.in: Regenerated.
 133

 135
 136         * boot-9.scm (eval-string, command-line, load-user-init): New
 137         functions.
 138
 139 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 140
 141         * boot-9.scm (log10): defined.
 142
 143 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 144
 145         * expect.scm (expect-select): correct the millisecond timeout
 146         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 147
 148 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 149
 150         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 151         instead of in libguile.
 152         (tm:sec etc.) new accessors for broken-down time.
 153         (set-tm:sec etc.) new setters for broken-down time.
 154
 155 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 156
 157         * boot-9.scm (netent:addrtype, servent:port): added missing
 158         procedures.
 159         (netent:net, servent:proto): repaired.
 160         (utsname:sysname etc.): new accessors for uname.
 161
 162 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 163
 164         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 165         sockaddr:port): new functions.
 166
 167 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 168
 169         * boot-9.scm: define accessor procedures for the objects returned
 170         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 171         passwd:name, where the first component is the name of the C structure
 172         and the second is the unprefixed C member name.)
 173
 174 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 175
 176         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 177         setservent): no longer take an argument, it was bogus.
 178
 179 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 180
 181         * boot-9.scm (scm-error): deleted, reimplemented in C.
 182
 183 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 184
 185         * boot-9.scm (process-define-module): Modified to handle both
 186         keywords and symbols.
 187
 188 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 189
 190         * slib.scm: update read usage.
 191
 192         * r4rs.scm: update primitive-load usage.
 193         Don't define read-sharp.
 194
 195         * boot-9.scm: use read-hash-extend to install extra read syntax.
 196         (read-sharp): removed.
 197         Adjust usage of primitive-load-path, read, which no longer take
 198         case_i or read-sharp arguments.
 199
 200 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 201
 202         * boot-9.scm: Added loading of session support module.
 203
 204         * debug.scm: Removed `display-application'.  (Replaced by
 205         primitive procedure.)
 206
 207         * boot-9.scm (beautify-user-module!): Don't add the root module
 208         interface to the end of the use-list of the root module.
 209
 210 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 211
 212         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 213
 214 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 215
 216         * boot-9.scm: check use-emacs-interface for emacs support.
 217
 218 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 219
 220         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 221         read gets EOF.
 222         * (exit): alias for quit.
 223
 224 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 225
 226         * boot-9.scm (error-catching-loop thunk): use a status variable to
 227         return the quit args.
 228         (scm-style-repl): call -quit, passing return value from
 229         error-catching-repl.  Make -quit return its args.
 230         stand-alone-repl: comment out, since it seems unused.
 231
 232         (error-catching-loop thunk): discard trailing junk after a (quit).
 233
 234 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 235
 236         * boot-9.scm: Removed the old printer code.
 237
 238         * r4rs.scm (apply, call-with-current-continuation): Added comment
 239         explaining why apply and call/cc need to be closures.
 240
 241         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 242         Removed. These definitions are already present in r4rs.scm.
 243
 244         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 245         stack before printing traced frames; Re-enable trace flag at end
 246         of handlers.
 247
 248 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 249
 250         * debug.scm: Add hook for reset of trace level at abort.
 251
 252         * boot-9.scm (run-hooks): New procedure.
 253         (add-hooks!): New macro.
 254         Change hooks to use these functions.
 255
 256         * debug.scm: *Warning* This feature is a bit premature.  I add
 257         it anyway because 1. it is very useful, and, 2. you can start
 258         making it less premature by complaining to me and by modifying
 259         the source! :-)
 260         (trace): Given one or more procedure objects, trace each one.
 261         Given no arguments, show all traced procedures.
 262         (untrace): Given one or more procedure objects, untrace each one.
 263         Given no arguments, untrace all traced procedures.  The tracing in
 264         Guile have an advantage to most other systems: We don't create new
 265         procedure objects, but mark the procedure objects themselves.
 266         This means that also anonymous and internal procedures can be
 267         traced.
 268
 269         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 270         and exit-frame exceptions.
 271
 272         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 273         (set-repl-prompt!): Setter for repl prompt.
 274         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 275         string, display it; if prompt is a thunk, call it and display its
 276         result; otherwise display "> ".
 277         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 278
 279         * r4rs.scm (%load-verbosely): Reverted change to
 280         `module-defined?', since the module system isn't bootstrapped when
 281         we load r4rs.scm.  This is just a temporary fix to make the
 282         repository version runnable.
 283
 284 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 285
 286         * boot-9.scm: Removed the enabling of debug evaluator and
 287         recording of source code positions.  This was placed there for our
 288         convenience, but it has already sneaked into the distribution
 289         once... so we'd better add this in our local copies instead when
 290         we need it.  (These options are normally enabled at the end of
 291         boot-9.scm when loading the debug module.)
 292
 293 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 294
 295         * boot-9.scm (module-defined?): New function.
 296         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 297         and eval.
 298         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 299         "defined?".
 300         * slib.scm (defined?): New function to take the place of the
 301         builtin "defined?".  It allways examines the slib module.
 302
 303 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 304
 305         * configure.in: Added AM_MAINTAINER_MODE
 306
 307 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 308
 309         * boot-9.scm (read-sharp): define directly, don't go through a
 310         %read-sharp layer.
 311
 312 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 313
 314         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 315         uniform-vector-set1! which doesn't exist.
 316
 317 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 318
 319         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 320         backtrace.c.)
 321
 322 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 323
 324         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 325         read-line): new procedures, see libguile/ChangeLog.
 326
 327 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 328
 329         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 330
 331         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 332         init-dynamic-module, dynamic-maybe-call,
 333         find-and-link-dynamic-module, link-dynamic-module,
 334         try-module-dynamic-link, registered-modules): New definitions for
 335         dynamic linking of modules.
 336         (resolve-module): Try to dynamically link the requested module
 337         after failing to load it as Scheme code.
 338
 339 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 340
 341         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 342
 343 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 344
 345         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 346         that's what it is.
 347
 348         * lineio.scm (make-line-buffering-input-port): Properly test for
 349         the case of an empty buffer list.  The old code assumed that '()
 350         was false.
 351
 352 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 353
 354         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 355         (use-modules <module name> ...) Put the the modules named by
 356         <module name> ... on the use list of the current module.
 357
 358 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 359
 360         * boot-9.scm (error-catching-loop): Remove message saying that
 361         typing "$" will put you in the debugger.  This isn't implemented
 362         yet.

 364 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 365
 366         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 367         been fixed, so this function is superfluous.
 368         (transform-usage-lambda): Use delq!, not delq-all!.
 369
 370 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 371
 372         * boot-9.scm (resolve-module): New optional parameter that
 373         controls whether autoloading is attempted or not. Default is #t.
 374         (process-define-module): Don't autoload the defined module.
 375         (try-module-autoload): Don't autoload the directory modules.
 376
 377         * boot-9.scm (process-define-module): Ensure that the-scm-module
 378         is last in the `uses' list to allow shadowing builtin
 379         bindings. All :use-module options are added in the order they
 380         appear in the arguments but before anything already on the list
 381         (such as the-scm-module).
 382
 383 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 384
 385         * slib.scm (slib-parent-dir): throw error if #f returned from
 386         %search-load-path.
 387
 388 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 389
 390         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 391         * Makefile.am, aclocal.m4: New files.
 392         * configure.in: Updated for Automake.
 393
 394 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 395
 396         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 397         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 398         function, use it accordingly.
 399
 400 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 401
 402         It's an "eval closure", not an "eval thunk."  A thunk is a
 403         function of no arguments.
 404         * boot-9.scm (module-type): Rename module field.
 405         (make-module, eval-in-module, make-root-module,
 406         set-current-module): Uses changed.
 407         (module-eval-closure, set-module-eval-closure!,
 408         root-module-closure): Renamed from module-eval-thunk,
 409         set-module-eval-thunk!, root-module-thunk.
 410         (set-current-module): Change uses of *top-level-lookup-thunk* to
 411         *top-level-eval-closure*.
 412
 413 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 414
 415         * slib.scm (slib-parent-dir): Use string-length, not length.
 416         (Thanks to Bernard Urban.)
 417
 418 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 419
 420         * boot-9.scm: The debugging evaluator and recording of positions
 421         aren't enabled by default any longer (they are switched on in
 422         debug.scm).  But during development we want to have them also
 423         *inside* boot-9.scm.  Therefore, two lines are added at the
 424         beginning of boot-9.scm to enable these.
 425
 426         Call `provide' so that `records' are included among the
 427         `*features*'.
 428
 429         The scheme for saving the stack has been adjusted: save-stack is
 430         now commonly available for saving the stack.  Calling `save-stack'
 431         sets a flag `stack-saved?' which prevents overwriting the stack.
 432         `stack-saved?' is reset at `abort'.
 433
 434         Spelling correction: seperate --> separate.
 435
 436         Removed `:'s that had creeped into some comments.
 437
 438         The repl now doesn't print #<unspecified> results any longer
 439         If the user wants to see this, he can do
 440         (assert-repl-print-unspecified #t) in his startup file.
 441
 442         The user now gets a friendly message instead of a backtrace at
 443         error.
 444
 445         Added `before-read-hook'.
 446
 447         Load module (ice-9 emacs) if option `-e' was specified.
 448
 449         (provide): New function.
 450
 451         (error): Save stack at entry, so that Guile entrails won't show up
 452         in backtraces.
 453
 454         (backtrace): New function.
 455
 456         (save-stack): Can now take arbitrary number of stack narrowing
 457         specifier pairs.  The first specifier in a pair controls inner
 458         border, the second the outer border.  A number means cut that
 459         number of frames, a procedure object means cut until that object
 460         is found in operator position in a frame.
 461
 462         * debug.scm: Enable debugging evaluator and recording of positions
 463         by default.
 464
 465         * slib.scm (slib:load): Adapt to the new behavior of
 466         primitive-load: It doesn't any longer try both with and without
 467         ".scm" extension.  (We don't want to use %search-load-path here.)
 468
 469         (implementation-vicinity): New function.  slib requires it
 470
 471         (library-vicinity): Updated.
 472
 473         Load "require.scm" in the library-vicinity.
 474
 475         (install-require-vicinity, install-require-module): New functions.
 476
 477 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 478
 479         * boot-9.scm (load-from-path): New function.
 480
 481         * boot-9.scm (try-load, basic-try-load, try-load-module,
 482         try-load): Deleted.  I don't think they're being used.
 483
 484         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 485         so they'll get distributed.
 486
 487         Get Guile to be a little less chatty by default.  The new user
 488         should see as little clutter as possible.
 489         * r4rs.scm (%load-verbosely): Make this #f by default.
 490         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 491         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 492
 493         * r4rs.scm: New file.
 494         * boot-9.scm: Load r4rs.scm, first thing.
 495         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 496         open-output-file, open-io-file, close-input-port,
 497         close-output-port, close-io-port, call-with-input-file,
 498         call-with-output-file, with-input-from-port, with-output-to-port,
 499         with-error-to-port, with-input-from-file, with-output-to-file,
 500         with-error-to-file, with-input-from-string, with-output-to-string,
 501         with-error-to-string, the-eof-object): Definitions moved to
 502         r4rs.scm.  Not all of them are R4RS, but those that are use those
 503         that are not.
 504         (load, %load-verbosely, %load-announce): Moved, along with code to
 505         set %load-hook, to r4rs.scm.
 506
 507         * test.scm: New file.
 508
 509         * boot-9.scm (integer?): Definition deleted, in favor of the one
 510         present in libguile (which used to be called int?).  I have no
 511         idea why integer? didn't just call int? to begin with.
 512
 513         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 514         =?, >?, and >=? deleted; they're defined that way by libguile now.
 515
 516         * boot-9.scm (load): Simplified; primitive-load does most of this
 517         work now.
 518         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 519         call %load-announce.
 520
 521 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 522
 523         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 524         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 525         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 526         components.
 527         (file-is-directory?): use stat:type.
 528
 529 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 530
 531         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 532         that's now taken care of in libguile, and in a way compatible with
 533         SCSH (which this isn't).
 534
 535 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 536
 537         * boot-9.scm: Formatting tweaks.
 538
 539 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 540
 541         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 542         after-error-hook, before-backtrace-hook and after-backtrace-hook
 543         to the error handler.  E.g.: fancy emacs support could plug into
 544         these.
 545         (save-stack): New function.  The stack is now made differently
 546         depending on the stack id.  (The motivation is to make a better
 547         choice regarding what stack frames to present to the user.)
 548         (error-catching-loop): Stack handling code moved outside into
 549         save-stack.
 550
 551 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 552
 553         * Makefile.in (scm_files): add expect.scm.
 554
 555         * expect.scm: new file ported from guile-iii.
 556
 557         * boot-9.scm: remove handle-system-error, after moving the code into
 558         error-catching-loop.
 559         Don't set 'throw-handler-default property on error keys.
 560         Just interpret (almost) any throw with 4 args as an error throw.
 561         Delete some try-load stuff that was already commented out.
 562
 563         Second thoughts, keep handle-system-error but call it from
 564         error-catching-loop.
 565
 566 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 567
 568         * boot-9.scm: Doc fixes.
 569         (make-module): Rework for readability.
 570         (make-root-module, make-scm-module): USES argument to make-module
 571         should be '(), not #f.
 572
 573         * boot-9.scm (try-load): %sys-load-path has been renamed to
 574         primitive-load-path; adjust call here.
 575
 576 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 577
 578         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 579         the stack to the correct place: when it is decided to generate an
 580         error-signal.
 581
 582 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 583
 584         * boot-9.scm (error-catching-loop, signal-handler,
 585         handle-system-error): Backtracing now works for signals aswell;
 586         Backtracing mechanism can now identify the stack root created by
 587         start-stack so that the user isn't exposed to system stack frames.
 588
 589 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 590
 591         * Makefile.in: Added threads.scm.
 592
 593 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 594
 595         * debug.scm (make-enable, make-disable): Simplified.
 596
 597         * boot-9.scm: Renamed %%throw-handler-default -->
 598         throw-handler-default.
 599         ((handle-system-error key . arg-list)): Changed the way errors are
 600         reported.
 601         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 602         acro.
 603         ((error-catching-loop thunk)): Introduce a lazy-catch into
 604         error-catching-loop so that the stack can be captured.
 605
 606 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 607
 608         * mapping.scm (hash-table-mapping): Explicitly request that
 609         make-vector fill new vectors with '(); this will make it easier to
 610         port Guile Scheme code to other Schemes.
 611         * boot-9.scm (make-print-style, make-print-table): Same.
 612
 613 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 614
 615         * boot-9.scm (load): rewritten again.
 616         Append "." to the default %load-path.
 617         (feature?): new function: checks for a symbol in the features list.
 618         (module-local-variable): remove apparently useless (caddr (list m v
 619         ...))
 620         (%load-announce): minor formatting change.
 621         (file-exists?): use access? if posix is featured.
 622         (file-is-directory?): use stat if i/o-extensions is featured.
 623         (try-module-autoload module-name): use file-exists? before
 624         file-is-directory?
 625
 626 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 627
 628         * boot-9.scm: Added conditional loading of threads.scm.
 629
 630         * threads.scm: New file.  Modified from the Cygnus-r0.3
 631         distribution.
 632
 633         * boot-9.scm (error-catching-loop): Added handling of key
 634         `switch-repl'.
 635
 636         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 637
 638 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 639
 640         * boot-9.scm (make-record-type, record-constructor): Don't assume
 641         the empty list is false when parsing the argument list.
 642
 643 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 644
 645         * boot-9.scm (signal-handler): Clean up logic.
 646
 647         * boot-9.scm (load): Assume %load-path is always bound.
 648
 649 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 650
 651         * boot-9.scm (error): replace another throw with scm-error.  Throw
 652         to 'misc-error instead of 'error (no need to distinguish these.)
 653         Don't set up 'error as a key.
 654         Set up regex-error as a key, if regex is available.
 655         (signal-handler): use scm-error, not throw.
 656
 657         (%try-load, try-load-with-path, %load, load-with-path,
 658         basic-try-load-with-path, basic-load-with-path,
 659         try-load-module-with-path,load-module-with-path): deleted, since
 660         they seem redundant.
 661         (try-load): define using %try-load, not try-load-with-path.
 662         (load): rewritten.  load tries to open the file directly and
 663         with a .scm extension before searching the library directories
 664         (should "." be added to %load-path?  then load could still open
 665         directly files starting with "/").
 666         (try-module-autoload): use load, not load-with-path.
 667         (%load-indent): deleted, -2 was causing errors.
 668
 669         (%read-sharp): use port-line, not line-number.
 670
 671 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 672
 673         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 674         straightforward to provide the equivalent functionality using
 675         (catch #t ...), so there's no need for the extra complexity.  2)
 676         Outside the context of a read-eval-print loop (which Guile should
 677         not require) it's not clear we should do anything more complicated
 678         than print an error and exit; the user or REPL can establish
 679         something better if it wants.  3) In that case, it's much more
 680         robust to just do it in the C code.
 681
 682 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 683
 684         * boot-9.scm (%try-load): define using primitive-load.  Previously
 685         %try-load itself was the primitive.
 686         (load-with-path): use scm-error instead of %load-announce-lossage.
 687         Errors are thrown to 'misc-error instead of 'could-not-load.
 688         (%load-announce-lossage): deleted.
 689
 690 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 691
 692         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 693         (make-record-type type-name fields): Temporarily remove support
 694         for printing of records (not possible yet with C printer).
 695
 696 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 697
 698         * boot-9.scm (file-exists?, file-is-directory): catch only
 699         system-error, not every kind of error.
 700         (scm-error): new procedure.
 701
 702 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 703
 704         * boot-9.scm: Formatting tweaks.
 705
 706 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 707
 708         * boot-9.scm (%%handle-system-error key): remove the code for
 709         SCM-style errors.  handle the case that an unexpected number
 710         of args are supplied.
 711         (%%system-errors): removed.
 712         (error): redefine using a throw with key and 4 args.
 713         ('error): associate 'error, 'error-signal keys with
 714         %%handle-system-error.
 715         (%%default-error-handler): removed.

 746         * boot-9.scm: Name change: value-ref --> local-ref
 747         resolved-ref --> nested-ref  Motivation: conformance to the other

 749         operates on vector, nested-ref operates on nested namespace,
 750         local-ref operates on the local nested namespace.
