   2
   3         * boot-9.scm (process-define-module): Modified to handle both
   4         keywords and symbols.
   5
   6 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
   7
   8         * slib.scm: update read usage.
   9
  10         * r4rs.scm: update primitive-load usage.
  11         Don't define read-sharp.
  12
  13         * boot-9.scm: use read-hash-extend to install extra read syntax.
  14         (read-sharp): removed.
  15         Adjust usage of primitive-load-path, read, which no longer take
  16         case_i or read-sharp arguments.
  17
  18 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  19
  20         * boot-9.scm: Added loading of session support module.
  21
  22         * debug.scm: Removed `display-application'.  (Replaced by
  23         primitive procedure.)
  24
  25         * boot-9.scm (beautify-user-module!): Don't add the root module
  26         interface to the end of the use-list of the root module.
  27
  28 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
  29
  30         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
  31
  32 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
  33
  34         * boot-9.scm: check use-emacs-interface for emacs support.
  35
  36 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
  37
  38         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
  39         read gets EOF.
  40         * (exit): alias for quit.
  41
  42 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
  43
  44         * boot-9.scm (error-catching-loop thunk): use a status variable to
  45         return the quit args.
  46         (scm-style-repl): call -quit, passing return value from
  47         error-catching-repl.  Make -quit return its args.
  48         stand-alone-repl: comment out, since it seems unused.
  49
  50         (error-catching-loop thunk): discard trailing junk after a (quit).
  51
  52 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  53
  54         * boot-9.scm: Removed the old printer code.
  55
  56         * r4rs.scm (apply, call-with-current-continuation): Added comment
  57         explaining why apply and call/cc need to be closures.
  58
  59         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
  60         Removed. These definitions are already present in r4rs.scm.
  61
  62         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
  63         stack before printing traced frames; Re-enable trace flag at end
  64         of handlers.
  65
  66 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  67
  68         * debug.scm: Add hook for reset of trace level at abort.
  69
  70         * boot-9.scm (run-hooks): New procedure.
  71         (add-hooks!): New macro.
  72         Change hooks to use these functions.
  73
  74 *       * debug.scm: *Warning* This feature is a bit premature.  I add
  75         it anyway because 1. it is very useful, and, 2. you can start
  76         making it less premature by complaining to me and by modifying
  77         the source! :-)
  78         (trace): Given one or more procedure objects, trace each one.
  79         Given no arguments, show all traced procedures.
  80         (untrace): Given one or more procedure objects, untrace each one.
  81         Given no arguments, untrace all traced procedures.  The tracing in
  82         Guile have an advantage to most other systems: We don't create new
  83         procedure objects, but mark the procedure objects themselves.
  84         This means that also anonymous and internal procedures can be
  85         traced.
  86
  87         * boot-9.scm (error-catching-loop): Added handling of apply-frame
  88         and exit-frame exceptions.
  89
  90 *       * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
  91         (set-repl-prompt!): Setter for repl prompt.
  92         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
  93         string, display it; if prompt is a thunk, call it and display its
  94         result; otherwise display "> ".
  95         (Change suggested by Roland Orre <orre@nada.kth.se>.)
  96
  97         * r4rs.scm (%load-verbosely): Reverted change to
  98         `module-defined?', since the module system isn't bootstrapped when
  99         we load r4rs.scm.  This is just a temporary fix to make the
 100         repository version runnable.
 101
 102 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 103
 104         * boot-9.scm: Removed the enabling of debug evaluator and
 105         recording of source code positions.  This was placed there for our
 106         convenience, but it has already sneaked into the distribution
 107         once... so we'd better add this in our local copies instead when
 108         we need it.  (These options are normally enabled at the end of
 109         boot-9.scm when loading the debug module.)
 110
 111 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 112
 113         * boot-9.scm (module-defined?): New function.
 114         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 115         and eval.
 116         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 117         "defined?".
 118         * slib.scm (defined?): New function to take the place of the
 119         builtin "defined?".  It allways examines the slib module.
 120
 121 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 122
 123         * configure.in: Added AM_MAINTAINER_MODE
 124
 125 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 126
 127         * boot-9.scm (read-sharp): define directly, don't go through a
 128         %read-sharp layer.
 129
 130 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 131
 132         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 133         uniform-vector-set1! which doesn't exist.
 134
 135 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 136
 137         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 138         backtrace.c.)
 139
 140 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 141
 142         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 143         read-line): new procedures, see libguile/ChangeLog.
 144
 145 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 146
 147         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 148
 149         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 150         init-dynamic-module, dynamic-maybe-call,
 151         find-and-link-dynamic-module, link-dynamic-module,
 152         try-module-dynamic-link, registered-modules): New definitions for
 153         dynamic linking of modules.
 154         (resolve-module): Try to dynamically link the requested module
 155         after failing to load it as Scheme code.
 156
 157 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 158
 159         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 160
 161 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 162
 163         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 164         that's what it is.
 165
 166         * lineio.scm (make-line-buffering-input-port): Properly test for
 167         the case of an empty buffer list.  The old code assumed that '()
 168         was false.
 169
 170 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 171
 172 *       * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 173         (use-modules <module name> ...) Put the the modules named by
 174         <module name> ... on the use list of the current module.
 175
 176 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 177
 178         * boot-9.scm (error-catching-loop): Remove message saying that
 179         typing "$" will put you in the debugger.  This isn't implemented
 180         yet.
 181
 182 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 183
 184         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 185         been fixed, so this function is superfluous.
 186         (transform-usage-lambda): Use delq!, not delq-all!.
 187
 188 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 189
 190         * boot-9.scm (resolve-module): New optional parameter that
 191         controls whether autoloading is attempted or not. Default is #t.
 192         (process-define-module): Don't autoload the defined module.
 193         (try-module-autoload): Don't autoload the directory modules.
 194
 195         * boot-9.scm (process-define-module): Ensure that the-scm-module
 196         is last in the `uses' list to allow shadowing builtin
 197         bindings. All :use-module options are added in the order they
 198         appear in the arguments but before anything already on the list
 199         (such as the-scm-module).
 200
 201 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 202
 203         * slib.scm (slib-parent-dir): throw error if #f returned from
 204         %search-load-path.
 205
 206 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 207
 208         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 209         * Makefile.am, aclocal.m4: New files.
 210         * configure.in: Updated for Automake.
 211
 212 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 213
 214         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 215         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 216         function, use it accordingly.
 217
 218 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 219
 220         It's an "eval closure", not an "eval thunk."  A thunk is a
 221         function of no arguments.
 222         * boot-9.scm (module-type): Rename module field.
 223         (make-module, eval-in-module, make-root-module,
 224         set-current-module): Uses changed.
 225         (module-eval-closure, set-module-eval-closure!,
 226         root-module-closure): Renamed from module-eval-thunk,
 227         set-module-eval-thunk!, root-module-thunk.
 228         (set-current-module): Change uses of *top-level-lookup-thunk* to
 229         *top-level-eval-closure*.
 230
 231 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 232
 233         * slib.scm (slib-parent-dir): Use string-length, not length.
 234         (Thanks to Bernard Urban.)
 235
 236 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 237
 238         * boot-9.scm: The debugging evaluator and recording of positions
 239         aren't enabled by default any longer (they are switched on in
 240         debug.scm).  But during development we want to have them also
 241         *inside* boot-9.scm.  Therefore, two lines are added at the
 242         beginning of boot-9.scm to enable these.
 243
 244         Call `provide' so that `records' are included among the
 245         `*features*'.
 246
 247         The scheme for saving the stack has been adjusted: save-stack is
 248         now commonly available for saving the stack.  Calling `save-stack'
 249         sets a flag `stack-saved?' which prevents overwriting the stack.
 250         `stack-saved?' is reset at `abort'.
 251
 252         Spelling correction: seperate --> separate.
 253
 254         Removed `:'s that had creeped into some comments.
 255
 256         The repl now doesn't print #<unspecified> results any longer
 257         If the user wants to see this, he can do
 258         (assert-repl-print-unspecified #t) in his startup file.
 259
 260         The user now gets a friendly message instead of a backtrace at
 261         error.
 262
 263         Added `before-read-hook'.
 264
 265         Load module (ice-9 emacs) if option `-e' was specified.
 266
 267         (provide): New function.
 268
 269         (error): Save stack at entry, so that Guile entrails won't show up
 270         in backtraces.
 271
 272         (backtrace): New function.
 273
 274         (save-stack): Can now take arbitrary number of stack narrowing
 275         specifier pairs.  The first specifier in a pair controls inner
 276         border, the second the outer border.  A number means cut that
 277         number of frames, a procedure object means cut until that object
 278         is found in operator position in a frame.
 279
 280         * debug.scm: Enable debugging evaluator and recording of positions
 281         by default.
 282
 283         * slib.scm (slib:load): Adapt to the new behavior of
 284         primitive-load: It doesn't any longer try both with and without
 285         ".scm" extension.  (We don't want to use %search-load-path here.)
 286
 287         (implementation-vicinity): New function.  slib requires it
 288
 289         (library-vicinity): Updated.
 290
 291         Load "require.scm" in the library-vicinity.
 292
 293         (install-require-vicinity, install-require-module): New functions.
 294
 295 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 296
 297         * boot-9.scm (load-from-path): New function.
 298
 299         * boot-9.scm (try-load, basic-try-load, try-load-module,
 300         try-load): Deleted.  I don't think they're being used.
 301
 302         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 303         so they'll get distributed.
 304
 305         Get Guile to be a little less chatty by default.  The new user
 306         should see as little clutter as possible.
 307         * r4rs.scm (%load-verbosely): Make this #f by default.
 308         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 309         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 310
 311         * r4rs.scm: New file.
 312         * boot-9.scm: Load r4rs.scm, first thing.
 313         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 314         open-output-file, open-io-file, close-input-port,
 315         close-output-port, close-io-port, call-with-input-file,
 316         call-with-output-file, with-input-from-port, with-output-to-port,
 317         with-error-to-port, with-input-from-file, with-output-to-file,
 318         with-error-to-file, with-input-from-string, with-output-to-string,
 319         with-error-to-string, the-eof-object): Definitions moved to
 320         r4rs.scm.  Not all of them are R4RS, but those that are use those
 321         that are not.
 322         (load, %load-verbosely, %load-announce): Moved, along with code to
 323         set %load-hook, to r4rs.scm.
 324
 325         * test.scm: New file.
 326
 327         * boot-9.scm (integer?): Definition deleted, in favor of the one
 328         present in libguile (which used to be called int?).  I have no
 329         idea why integer? didn't just call int? to begin with.
 330
 331         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 332         =?, >?, and >=? deleted; they're defined that way by libguile now.
 333
 334         * boot-9.scm (load): Simplified; primitive-load does most of this
 335         work now.
 336         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 337         call %load-announce.
 338
 339 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 340
 341         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 342         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 343         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 344         components.
 345         (file-is-directory?): use stat:type.
 346
 347 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 348
 349         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 350         that's now taken care of in libguile, and in a way compatible with
 351         SCSH (which this isn't).
 352
 353 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 354
 355         * boot-9.scm: Formatting tweaks.
 356
 357 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 358
 359         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 360         after-error-hook, before-backtrace-hook and after-backtrace-hook
 361         to the error handler.  E.g.: fancy emacs support could plug into
 362         these.
 363         (save-stack): New function.  The stack is now made differently
 364         depending on the stack id.  (The motivation is to make a better
 365         choice regarding what stack frames to present to the user.)
 366         (error-catching-loop): Stack handling code moved outside into
 367         save-stack.
 368
 369 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 370
 371         * Makefile.in (scm_files): add expect.scm.
 372
 373         * expect.scm: new file ported from guile-iii.
 374
 375         * boot-9.scm: remove handle-system-error, after moving the code into
 376         error-catching-loop.
 377         Don't set 'throw-handler-default property on error keys.
 378         Just interpret (almost) any throw with 4 args as an error throw.
 379         Delete some try-load stuff that was already commented out.
 380
 381         Second thoughts, keep handle-system-error but call it from
 382         error-catching-loop.
 383
 384 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 385
 386         * boot-9.scm: Doc fixes.
 387         (make-module): Rework for readability.
 388         (make-root-module, make-scm-module): USES argument to make-module
 389         should be '(), not #f.
 390
 391         * boot-9.scm (try-load): %sys-load-path has been renamed to
 392         primitive-load-path; adjust call here.
 393
 394 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 395
 396         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 397         the stack to the correct place: when it is decided to generate an
 398         error-signal.
 399
 400 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 401
 402         * boot-9.scm (error-catching-loop, signal-handler,
 403         handle-system-error): Backtracing now works for signals aswell;
 404         Backtracing mechanism can now identify the stack root created by
 405         start-stack so that the user isn't exposed to system stack frames.
 406
 407 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 408
 409         * Makefile.in: Added threads.scm.
 410
 411 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 412
 413         * debug.scm (make-enable, make-disable): Simplified.
 414
 415         * boot-9.scm: Renamed %%throw-handler-default -->
 416         throw-handler-default.
 417         ((handle-system-error key . arg-list)): Changed the way errors are
 418         reported.
 419         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 420         acro.
 421         ((error-catching-loop thunk)): Introduce a lazy-catch into
 422         error-catching-loop so that the stack can be captured.
 423
 424 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 425
 426         * mapping.scm (hash-table-mapping): Explicitly request that
 427         make-vector fill new vectors with '(); this will make it easier to
 428         port Guile Scheme code to other Schemes.
 429         * boot-9.scm (make-print-style, make-print-table): Same.
 430
 431 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 432
 433         * boot-9.scm (load): rewritten again.
 434         Append "." to the default %load-path.
 435         (feature?): new function: checks for a symbol in the features list.
 436         (module-local-variable): remove apparently useless (caddr (list m v
 437         ...))
 438         (%load-announce): minor formatting change.
 439         (file-exists?): use access? if posix is featured.
 440         (file-is-directory?): use stat if i/o-extensions is featured.
 441         (try-module-autoload module-name): use file-exists? before
 442         file-is-directory?
 443
 444 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 445
 446         * boot-9.scm: Added conditional loading of threads.scm.
 447
 448         * threads.scm: New file.  Modified from the Cygnus-r0.3
 449         distribution.
 450
 451         * boot-9.scm (error-catching-loop): Added handling of key
 452         `switch-repl'.
 453
 454         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 455
 456 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 457
 458         * boot-9.scm (make-record-type, record-constructor): Don't assume
 459         the empty list is false when parsing the argument list.
 460
 461 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 462
 463         * boot-9.scm (signal-handler): Clean up logic.
 464
 465         * boot-9.scm (load): Assume %load-path is always bound.
 466
 467 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 468
 469         * boot-9.scm (error): replace another throw with scm-error.  Throw
 470         to 'misc-error instead of 'error (no need to distinguish these.)
 471         Don't set up 'error as a key.
 472         Set up regex-error as a key, if regex is available.
 473         (signal-handler): use scm-error, not throw.
 474
 475         (%try-load, try-load-with-path, %load, load-with-path,
 476         basic-try-load-with-path, basic-load-with-path,
 477         try-load-module-with-path,load-module-with-path): deleted, since
 478         they seem redundant.
 479         (try-load): define using %try-load, not try-load-with-path.
 480         (load): rewritten.  load tries to open the file directly and
 481         with a .scm extension before searching the library directories
 482         (should "." be added to %load-path?  then load could still open
 483         directly files starting with "/").
 484         (try-module-autoload): use load, not load-with-path.
 485         (%load-indent): deleted, -2 was causing errors.
 486
 487         (%read-sharp): use port-line, not line-number.
 488
 489 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 490
 491         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 492         straightforward to provide the equivalent functionality using
 493         (catch #t ...), so there's no need for the extra complexity.  2)
 494         Outside the context of a read-eval-print loop (which Guile should
 495         not require) it's not clear we should do anything more complicated
 496         than print an error and exit; the user or REPL can establish
 497         something better if it wants.  3) In that case, it's much more
 498         robust to just do it in the C code.
 499
 500 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 501
 502         * boot-9.scm (%try-load): define using primitive-load.  Previously
 503         %try-load itself was the primitive.
 504         (load-with-path): use scm-error instead of %load-announce-lossage.
 505         Errors are thrown to 'misc-error instead of 'could-not-load.
 506         (%load-announce-lossage): deleted.
 507
 508 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 509
 510         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 511         (make-record-type type-name fields): Temporarily remove support
 512         for printing of records (not possible yet with C printer).
 513
 514 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 515
 516         * boot-9.scm (file-exists?, file-is-directory): catch only
 517         system-error, not every kind of error.
 518         (scm-error): new procedure.
 519
 520 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 521
 522         * boot-9.scm: Formatting tweaks.
 523
 524 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 525
 526         * boot-9.scm (%%handle-system-error key): remove the code for
 527         SCM-style errors.  handle the case that an unexpected number
 528         of args are supplied.
 529         (%%system-errors): removed.
 530         (error): redefine using a throw with key and 4 args.
 531         ('error): associate 'error, 'error-signal keys with
 532         %%handle-system-error.
 533         (%%default-error-handler): removed.
 534         (signal-handler): throw with 4 args and use the error-signal key.
 535         Create an error message instead of using numerical codes.
 536         (%%bad-throw): call error instead of throw if key not found.
 537
 538 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 539
 540         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 541         (%%handle-system-error key): check subr is not #f before printing.
 542         Recognize %s (embed an argument using "display") and
 543         %S (embed an argument using "write").
 544
 545 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 546
 547         * boot-9.scm (%%handle-system-error key): set args and rest to
 548         the empty list if they are #f.
 549         Initialize out-of-range as an error key.
 550
 551 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 552
 553         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 554
 555         * boot-9.scm: remove leading %% from references to '%%system-error.
 556         (%%handle-system-error): don't pass all the thrown arguments when
 557         aborting, just the key and subr.
 558         Remove the code to "Install default handlers for built-in errors."
 559         Remove the definition of the syserror procedure.
 560         Associate 'numerical-overflow with default handler.
 561
 562 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 563
 564         * boot-9.scm: Name change: value-ref --> local-ref
 565         resolved-ref --> nested-ref  Motivation: conformance to the other
 566         dictionary operators: list-ref operates on list, vector-ref
 567         operates on vector, nested-ref operates on nested namespace,
 568         local-ref operates on the local nested namespace.
 569
 570 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 571
 572         * boot-9.scm (%%handle-system-error): recognise errors thrown
 573         by lgh-error (fill-message etc.)
 574         (fill-message): check first whether args is null.
 575         (fill-message): bug fix and check that args is a list.
 576
 577 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
 578
 579         * boot-9.scm: %load-path is initialized in C code now.
 580         (implementation-vicinity, parse-path): Deleted, along with code to
 581         initialize %load-path.
 582
 583         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 584         "/", use one to separate it from the file.
 585
 586 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 587
 588         * boot-9.scm (%load-path): Add the site directory.
 589         Add the directory named after the version number.
 590         Prepend the version number to the other directories in the path.
 591         Simplify by mapping the common prefix onto each item.
 592         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
 593         sitedatadir): New definitions.
 594         (libparent, libdir, install_path): Replaced by above.
 595         (install): Create the above directories.
 596         Put the source files into subpkgdatadir.
 597         (uninstall): Remove the above directories.
 598
 599 Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 600
 601         Don't use the PLUGIN system to gather information for the
 602         Makefile's distribution and installation targets; just put it all
 603         in the Makefile directly.
 604         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 605         for these.
 606         * configure.in: Remove code that gets and substitutes scm_files and
 607         aux_files.
 608         * Makefile.in (scm_files, aux_files): Write out the list of files
 609         here, where people expect to find them.
 610

 612
 613         * boot-9.scm: Preliminary solution: optionally load the debug
 614         module.  Changed "gls" to "guile1.0b3".
 615
 616         * debug.scm: New file: debug extensions.
 617
 618 Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 619
 620         * boot-9.scm (print-vector): Renamed weak-hash-table? -->
 621         weak-key-hash-table?.  (Again!)
 622
 623 Tue Aug 20 07:31:39 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 624
 625         * boot-9.scm (print-vector, macro-table, xformer-table):
 626         Renamed weak-hash-table --> weak-key-hash-table.

 633         * boot-9.scm (*null-device*): global constant from goonix.
 634         (move->fdes): adjusted for boolean primitive-move->fdes.  return
 635         the modified port, always set revealed count to 1 (SCSH compatible).
 636         (release-port-handle port): from goonix (SCSH compatible).
 637         (%open-file): removed.
 638         (open-input-file, open-output-file, file-exists?, file-is-directory?):
 639         modified for open-file change (does not return #f).
 640
 641 Thu Aug  1 02:52:42 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 642
 643         * Makefile.in (dist-dir): New target for new dist system.
 644         (manifest): Deleted.
 645         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
 646         directory, and needs special treatment in the dist-dir target.
 647
 648 Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>
 649
 650         * boot-9.scm: remove the wrappers for '%' system primitives,
 651         now that they throw errors directly.
 652         remove make-simple-wrapper and similar functions.
 653         protect a call to getenv which may now throw an exception.
 654
 655 Wed Jul 31 23:44:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
 656
 657         * boot-9.scm (false-if-exception): new macro.
 658
