   9
  10 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>

  19         Adjust usage of primitive-load-path, read, which no longer take
  20         case_i or read-sharp arguments.
  21
  22 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  23
  24         * boot-9.scm: Added loading of session support module.
  25
  26         * debug.scm: Removed `display-application'.  (Replaced by

  30         interface to the end of the use-list of the root module.
  31
  32 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
  33
  34         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
  35
  36 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
  37
  38         * boot-9.scm: check use-emacs-interface for emacs support.
  39
  40 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
  41
  42         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
  43         read gets EOF.
  44         * (exit): alias for quit.
  45
  46 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
  47
  48         * boot-9.scm (error-catching-loop thunk): use a status variable to
  49         return the quit args.
  50         (scm-style-repl): call -quit, passing return value from
  51         error-catching-repl.  Make -quit return its args.
  52         stand-alone-repl: comment out, since it seems unused.
  53
  54         (error-catching-loop thunk): discard trailing junk after a (quit).
  55
  56 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  57
  58         * boot-9.scm: Removed the old printer code.
  59
  60         * r4rs.scm (apply, call-with-current-continuation): Added comment
  61         explaining why apply and call/cc need to be closures.
  62
  63         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
  64         Removed. These definitions are already present in r4rs.scm.
  65
  66         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
  67         stack before printing traced frames; Re-enable trace flag at end
  68         of handlers.
  69
  70 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  71
  72         * debug.scm: Add hook for reset of trace level at abort.
  73
  74         * boot-9.scm (run-hooks): New procedure.
  75         (add-hooks!): New macro.
  76         Change hooks to use these functions.
  77
  78 *       * debug.scm: *Warning* This feature is a bit premature.  I add
  79         it anyway because 1. it is very useful, and, 2. you can start
  80         making it less premature by complaining to me and by modifying
  81         the source! :-)
  82         (trace): Given one or more procedure objects, trace each one.
  83         Given no arguments, show all traced procedures.
  84         (untrace): Given one or more procedure objects, untrace each one.
  85         Given no arguments, untrace all traced procedures.  The tracing in
  86         Guile have an advantage to most other systems: We don't create new
  87         procedure objects, but mark the procedure objects themselves.
  88         This means that also anonymous and internal procedures can be
  89         traced.
  90
  91         * boot-9.scm (error-catching-loop): Added handling of apply-frame
  92         and exit-frame exceptions.
  93
  94 *       * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
  95         (set-repl-prompt!): Setter for repl prompt.
  96         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
  97         string, display it; if prompt is a thunk, call it and display its
  98         result; otherwise display "> ".
  99         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 100
 101         * r4rs.scm (%load-verbosely): Reverted change to
 102         `module-defined?', since the module system isn't bootstrapped when
 103         we load r4rs.scm.  This is just a temporary fix to make the
 104         repository version runnable.
 105
 106 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 107
 108         * boot-9.scm: Removed the enabling of debug evaluator and
 109         recording of source code positions.  This was placed there for our
 110         convenience, but it has already sneaked into the distribution
 111         once... so we'd better add this in our local copies instead when
 112         we need it.  (These options are normally enabled at the end of
 113         boot-9.scm when loading the debug module.)
 114
 115 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 116
 117         * boot-9.scm (module-defined?): New function.
 118         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 119         and eval.
 120         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 121         "defined?".
 122         * slib.scm (defined?): New function to take the place of the
 123         builtin "defined?".  It allways examines the slib module.
 124
 125 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 126
 127         * configure.in: Added AM_MAINTAINER_MODE
 128
 129 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 130
 131         * boot-9.scm (read-sharp): define directly, don't go through a
 132         %read-sharp layer.
 133
 134 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 135
 136         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 137         uniform-vector-set1! which doesn't exist.
 138
 139 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 140
 141         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 142         backtrace.c.)
 143
 144 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 145
 146         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 147         read-line): new procedures, see libguile/ChangeLog.
 148
 149 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 150
 151         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 152
 153         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 154         init-dynamic-module, dynamic-maybe-call,
 155         find-and-link-dynamic-module, link-dynamic-module,
 156         try-module-dynamic-link, registered-modules): New definitions for
 157         dynamic linking of modules.
 158         (resolve-module): Try to dynamically link the requested module
 159         after failing to load it as Scheme code.
 160
 161 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 162
 163         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 164
 165 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 166
 167         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 168         that's what it is.
 169
 170         * lineio.scm (make-line-buffering-input-port): Properly test for
 171         the case of an empty buffer list.  The old code assumed that '()
 172         was false.
 173
 174 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 175
 176 *       * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 177         (use-modules <module name> ...) Put the the modules named by
 178         <module name> ... on the use list of the current module.
 179
 180 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 181
 182         * boot-9.scm (error-catching-loop): Remove message saying that
 183         typing "$" will put you in the debugger.  This isn't implemented
 184         yet.
 185
 186 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 187
 188         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 189         been fixed, so this function is superfluous.
 190         (transform-usage-lambda): Use delq!, not delq-all!.
 191
 192 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 193
 194         * boot-9.scm (resolve-module): New optional parameter that
 195         controls whether autoloading is attempted or not. Default is #t.
 196         (process-define-module): Don't autoload the defined module.
 197         (try-module-autoload): Don't autoload the directory modules.
 198
 199         * boot-9.scm (process-define-module): Ensure that the-scm-module
 200         is last in the `uses' list to allow shadowing builtin
 201         bindings. All :use-module options are added in the order they
 202         appear in the arguments but before anything already on the list
 203         (such as the-scm-module).
 204
 205 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 206
 207         * slib.scm (slib-parent-dir): throw error if #f returned from
 208         %search-load-path.
 209
 210 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 211
 212         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 213         * Makefile.am, aclocal.m4: New files.
 214         * configure.in: Updated for Automake.
 215
 216 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 217
 218         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 219         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 220         function, use it accordingly.
 221
 222 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 223
 224         It's an "eval closure", not an "eval thunk."  A thunk is a
 225         function of no arguments.
 226         * boot-9.scm (module-type): Rename module field.
 227         (make-module, eval-in-module, make-root-module,
 228         set-current-module): Uses changed.
 229         (module-eval-closure, set-module-eval-closure!,
 230         root-module-closure): Renamed from module-eval-thunk,
 231         set-module-eval-thunk!, root-module-thunk.
 232         (set-current-module): Change uses of *top-level-lookup-thunk* to
 233         *top-level-eval-closure*.
 234
 235 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 236
 237         * slib.scm (slib-parent-dir): Use string-length, not length.
 238         (Thanks to Bernard Urban.)
 239
 240 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 241
 242         * boot-9.scm: The debugging evaluator and recording of positions
 243         aren't enabled by default any longer (they are switched on in
 244         debug.scm).  But during development we want to have them also
 245         *inside* boot-9.scm.  Therefore, two lines are added at the
 246         beginning of boot-9.scm to enable these.
 247
 248         Call `provide' so that `records' are included among the
 249         `*features*'.
 250
 251         The scheme for saving the stack has been adjusted: save-stack is
 252         now commonly available for saving the stack.  Calling `save-stack'
 253         sets a flag `stack-saved?' which prevents overwriting the stack.
 254         `stack-saved?' is reset at `abort'.
 255
 256         Spelling correction: seperate --> separate.
 257
 258         Removed `:'s that had creeped into some comments.
 259
 260         The repl now doesn't print #<unspecified> results any longer
 261         If the user wants to see this, he can do
 262         (assert-repl-print-unspecified #t) in his startup file.
 263
 264         The user now gets a friendly message instead of a backtrace at
 265         error.
 266
 267         Added `before-read-hook'.
 268
 269         Load module (ice-9 emacs) if option `-e' was specified.
 270
 271         (provide): New function.
 272
 273         (error): Save stack at entry, so that Guile entrails won't show up
 274         in backtraces.
 275
 276         (backtrace): New function.
 277
 278         (save-stack): Can now take arbitrary number of stack narrowing
 279         specifier pairs.  The first specifier in a pair controls inner
 280         border, the second the outer border.  A number means cut that
 281         number of frames, a procedure object means cut until that object
 282         is found in operator position in a frame.
 283
 284         * debug.scm: Enable debugging evaluator and recording of positions
 285         by default.
 286
 287         * slib.scm (slib:load): Adapt to the new behavior of
 288         primitive-load: It doesn't any longer try both with and without
 289         ".scm" extension.  (We don't want to use %search-load-path here.)
 290
 291         (implementation-vicinity): New function.  slib requires it
 292
 293         (library-vicinity): Updated.
 294
 295         Load "require.scm" in the library-vicinity.
 296
 297         (install-require-vicinity, install-require-module): New functions.
 298
 299 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 300
 301         * boot-9.scm (load-from-path): New function.
 302
 303         * boot-9.scm (try-load, basic-try-load, try-load-module,
 304         try-load): Deleted.  I don't think they're being used.
 305
 306         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 307         so they'll get distributed.
 308
 309         Get Guile to be a little less chatty by default.  The new user
 310         should see as little clutter as possible.
 311         * r4rs.scm (%load-verbosely): Make this #f by default.
 312         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 313         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 314
 315         * r4rs.scm: New file.
 316         * boot-9.scm: Load r4rs.scm, first thing.
 317         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 318         open-output-file, open-io-file, close-input-port,
 319         close-output-port, close-io-port, call-with-input-file,
 320         call-with-output-file, with-input-from-port, with-output-to-port,
 321         with-error-to-port, with-input-from-file, with-output-to-file,
 322         with-error-to-file, with-input-from-string, with-output-to-string,
 323         with-error-to-string, the-eof-object): Definitions moved to
 324         r4rs.scm.  Not all of them are R4RS, but those that are use those
 325         that are not.
 326         (load, %load-verbosely, %load-announce): Moved, along with code to
 327         set %load-hook, to r4rs.scm.
 328
 329         * test.scm: New file.
 330
 331         * boot-9.scm (integer?): Definition deleted, in favor of the one
 332         present in libguile (which used to be called int?).  I have no
 333         idea why integer? didn't just call int? to begin with.
 334
 335         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 336         =?, >?, and >=? deleted; they're defined that way by libguile now.
 337
 338         * boot-9.scm (load): Simplified; primitive-load does most of this
 339         work now.
 340         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 341         call %load-announce.
 342
 343 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 344
 345         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 346         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 347         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 348         components.
 349         (file-is-directory?): use stat:type.
 350
 351 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 352
 353         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 354         that's now taken care of in libguile, and in a way compatible with
 355         SCSH (which this isn't).
 356
 357 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 358
 359         * boot-9.scm: Formatting tweaks.
 360
 361 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 362
 363         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 364         after-error-hook, before-backtrace-hook and after-backtrace-hook
 365         to the error handler.  E.g.: fancy emacs support could plug into
 366         these.
 367         (save-stack): New function.  The stack is now made differently
 368         depending on the stack id.  (The motivation is to make a better
 369         choice regarding what stack frames to present to the user.)
 370         (error-catching-loop): Stack handling code moved outside into
 371         save-stack.
 372
 373 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 374
 375         * Makefile.in (scm_files): add expect.scm.
 376
 377         * expect.scm: new file ported from guile-iii.
 378
 379         * boot-9.scm: remove handle-system-error, after moving the code into
 380         error-catching-loop.
 381         Don't set 'throw-handler-default property on error keys.
 382         Just interpret (almost) any throw with 4 args as an error throw.
 383         Delete some try-load stuff that was already commented out.
 384
 385         Second thoughts, keep handle-system-error but call it from
 386         error-catching-loop.
 387
 388 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 389
 390         * boot-9.scm: Doc fixes.
 391         (make-module): Rework for readability.
 392         (make-root-module, make-scm-module): USES argument to make-module
 393         should be '(), not #f.
 394
 395         * boot-9.scm (try-load): %sys-load-path has been renamed to
 396         primitive-load-path; adjust call here.
 397
 398 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 399
 400         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 401         the stack to the correct place: when it is decided to generate an
 402         error-signal.
 403
 404 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 405
 406         * boot-9.scm (error-catching-loop, signal-handler,
 407         handle-system-error): Backtracing now works for signals aswell;
 408         Backtracing mechanism can now identify the stack root created by
 409         start-stack so that the user isn't exposed to system stack frames.
 410
 411 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 412
 413         * Makefile.in: Added threads.scm.
 414
 415 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 416
 417         * debug.scm (make-enable, make-disable): Simplified.
 418
 419         * boot-9.scm: Renamed %%throw-handler-default -->
 420         throw-handler-default.
 421         ((handle-system-error key . arg-list)): Changed the way errors are
 422         reported.
 423         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 424         acro.
 425         ((error-catching-loop thunk)): Introduce a lazy-catch into
 426         error-catching-loop so that the stack can be captured.
 427
 428 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 429
 430         * mapping.scm (hash-table-mapping): Explicitly request that
 431         make-vector fill new vectors with '(); this will make it easier to
 432         port Guile Scheme code to other Schemes.
 433         * boot-9.scm (make-print-style, make-print-table): Same.
 434
 435 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 436
 437         * boot-9.scm (load): rewritten again.
 438         Append "." to the default %load-path.
 439         (feature?): new function: checks for a symbol in the features list.
 440         (module-local-variable): remove apparently useless (caddr (list m v
 441         ...))
 442         (%load-announce): minor formatting change.
 443         (file-exists?): use access? if posix is featured.
 444         (file-is-directory?): use stat if i/o-extensions is featured.
 445         (try-module-autoload module-name): use file-exists? before
 446         file-is-directory?
 447
 448 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 449
 450         * boot-9.scm: Added conditional loading of threads.scm.
 451
 452         * threads.scm: New file.  Modified from the Cygnus-r0.3
 453         distribution.
 454
 455         * boot-9.scm (error-catching-loop): Added handling of key
 456         `switch-repl'.
 457
 458         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 459
 460 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 461
 462         * boot-9.scm (make-record-type, record-constructor): Don't assume
 463         the empty list is false when parsing the argument list.
 464
 465 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 466
 467         * boot-9.scm (signal-handler): Clean up logic.
 468
 469         * boot-9.scm (load): Assume %load-path is always bound.
 470
 471 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 472
 473         * boot-9.scm (error): replace another throw with scm-error.  Throw
 474         to 'misc-error instead of 'error (no need to distinguish these.)
 475         Don't set up 'error as a key.
 476         Set up regex-error as a key, if regex is available.
 477         (signal-handler): use scm-error, not throw.
 478
 479         (%try-load, try-load-with-path, %load, load-with-path,
 480         basic-try-load-with-path, basic-load-with-path,
 481         try-load-module-with-path,load-module-with-path): deleted, since
 482         they seem redundant.
 483         (try-load): define using %try-load, not try-load-with-path.
 484         (load): rewritten.  load tries to open the file directly and
 485         with a .scm extension before searching the library directories
 486         (should "." be added to %load-path?  then load could still open
 487         directly files starting with "/").
 488         (try-module-autoload): use load, not load-with-path.
 489         (%load-indent): deleted, -2 was causing errors.
 490
 491         (%read-sharp): use port-line, not line-number.
 492
 493 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 494
 495         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 496         straightforward to provide the equivalent functionality using
 497         (catch #t ...), so there's no need for the extra complexity.  2)
 498         Outside the context of a read-eval-print loop (which Guile should
 499         not require) it's not clear we should do anything more complicated
 500         than print an error and exit; the user or REPL can establish
 501         something better if it wants.  3) In that case, it's much more
 502         robust to just do it in the C code.
 503
 504 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 505
 506         * boot-9.scm (%try-load): define using primitive-load.  Previously
 507         %try-load itself was the primitive.
 508         (load-with-path): use scm-error instead of %load-announce-lossage.
 509         Errors are thrown to 'misc-error instead of 'could-not-load.
 510         (%load-announce-lossage): deleted.
 511
 512 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 513
 514         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 515         (make-record-type type-name fields): Temporarily remove support
 516         for printing of records (not possible yet with C printer).
 517
 518 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 519
 520         * boot-9.scm (file-exists?, file-is-directory): catch only
 521         system-error, not every kind of error.
 522         (scm-error): new procedure.
 523
 524 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 525
 526         * boot-9.scm: Formatting tweaks.
 527
 528 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 529
 530         * boot-9.scm (%%handle-system-error key): remove the code for
 531         SCM-style errors.  handle the case that an unexpected number
 532         of args are supplied.
 533         (%%system-errors): removed.
 534         (error): redefine using a throw with key and 4 args.
 535         ('error): associate 'error, 'error-signal keys with
 536         %%handle-system-error.
 537         (%%default-error-handler): removed.
 538         (signal-handler): throw with 4 args and use the error-signal key.
 539         Create an error message instead of using numerical codes.
 540         (%%bad-throw): call error instead of throw if key not found.
 541
 542 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 543
 544         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 545         (%%handle-system-error key): check subr is not #f before printing.
 546         Recognize %s (embed an argument using "display") and
 547         %S (embed an argument using "write").
 548
 549 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 550
 551         * boot-9.scm (%%handle-system-error key): set args and rest to
 552         the empty list if they are #f.
 553         Initialize out-of-range as an error key.
 554
 555 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 556
 557         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 558
 559         * boot-9.scm: remove leading %% from references to '%%system-error.
 560         (%%handle-system-error): don't pass all the thrown arguments when
 561         aborting, just the key and subr.
 562         Remove the code to "Install default handlers for built-in errors."
 563         Remove the definition of the syserror procedure.
 564         Associate 'numerical-overflow with default handler.
 565
 566 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 567
 568         * boot-9.scm: Name change: value-ref --> local-ref
 569         resolved-ref --> nested-ref  Motivation: conformance to the other
 570         dictionary operators: list-ref operates on list, vector-ref
 571         operates on vector, nested-ref operates on nested namespace,
 572         local-ref operates on the local nested namespace.
 573
 574 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 575
 576         * boot-9.scm (%%handle-system-error): recognise errors thrown
 577         by lgh-error (fill-message etc.)
 578         (fill-message): check first whether args is null.
 579         (fill-message): bug fix and check that args is a list.
 580
 581 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
 582
 583         * boot-9.scm: %load-path is initialized in C code now.
 584         (implementation-vicinity, parse-path): Deleted, along with code to
 585         initialize %load-path.
 586
 587         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 588         "/", use one to separate it from the file.
 589
 590 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 591
 592         * boot-9.scm (%load-path): Add the site directory.
 593         Add the directory named after the version number.
 594         Prepend the version number to the other directories in the path.
 595         Simplify by mapping the common prefix onto each item.
 596         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
 597         sitedatadir): New definitions.
 598         (libparent, libdir, install_path): Replaced by above.
 599         (install): Create the above directories.
 600         Put the source files into subpkgdatadir.
 601         (uninstall): Remove the above directories.
 602
 603 Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 604
 605         Don't use the PLUGIN system to gather information for the
 606         Makefile's distribution and installation targets; just put it all
 607         in the Makefile directly.
 608         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 609         for these.
 610         * configure.in: Remove code that gets and substitutes scm_files and
 611         aux_files.
 612         * Makefile.in (scm_files, aux_files): Write out the list of files
 613         here, where people expect to find them.
 614
 615 Fri Aug 23 06:44:36 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 616
 617         * boot-9.scm: Preliminary solution: optionally load the debug
 618         module.  Changed "gls" to "guile1.0b3".
 619
 620         * debug.scm: New file: debug extensions.
 621
 622 Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 623
 624         * boot-9.scm (print-vector): Renamed weak-hash-table? -->
 625         weak-key-hash-table?.  (Again!)
 626
 627 Tue Aug 20 07:31:39 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 628
 629         * boot-9.scm (print-vector, macro-table, xformer-table):
 630         Renamed weak-hash-table --> weak-key-hash-table.
 631

 641         (%open-file): removed.
 642         (open-input-file, open-output-file, file-exists?, file-is-directory?):
 643         modified for open-file change (does not return #f).
 644
 645 Thu Aug  1 02:52:42 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 646
 647         * Makefile.in (dist-dir): New target for new dist system.
 648         (manifest): Deleted.
 649         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
 650         directory, and needs special treatment in the dist-dir target.
 651
 652 Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>
 653
 654         * boot-9.scm: remove the wrappers for '%' system primitives,
 655         now that they throw errors directly.
 656         remove make-simple-wrapper and similar functions.
 657         protect a call to getenv which may now throw an exception.
 658
 659 Wed Jul 31 23:44:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
 660
 661         * boot-9.scm (false-if-exception): new macro.
 662

 666
 667
