  23         sockaddr:port): new functions.
  24
  25 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
  26
  27         * boot-9.scm: define accessor procedures for the objects returned
  28         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
  29         passwd:name, where the first component is the name of the C structure
  30         and the second is the unprefixed C member name.)
  31
  32 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
  33
  34 *       * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
  35         setservent): no longer take an argument, it was bogus.
  36
  37 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
  38
  39         * boot-9.scm (scm-error): deleted, reimplemented in C.
  40
  41 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  42
  43         * boot-9.scm (process-define-module): Modified to handle both
  44         keywords and symbols.
  45
  46 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
  47
  48         * slib.scm: update read usage.
  49
  50         * r4rs.scm: update primitive-load usage.
  51         Don't define read-sharp.
  52
  53         * boot-9.scm: use read-hash-extend to install extra read syntax.
  54         (read-sharp): removed.
  55         Adjust usage of primitive-load-path, read, which no longer take
  56         case_i or read-sharp arguments.
  57
  58 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  59
  60         * boot-9.scm: Added loading of session support module.
  61
  62         * debug.scm: Removed `display-application'.  (Replaced by
  63         primitive procedure.)

  66         interface to the end of the use-list of the root module.

  69
  70         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
  71
  72 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
  73
  74         * boot-9.scm: check use-emacs-interface for emacs support.
  75
  76 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
  77
  78         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
  79         read gets EOF.
  80         * (exit): alias for quit.
  81
  82 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
  83
  84         * boot-9.scm (error-catching-loop thunk): use a status variable to
  85         return the quit args.
  86         (scm-style-repl): call -quit, passing return value from
  87         error-catching-repl.  Make -quit return its args.
  88         stand-alone-repl: comment out, since it seems unused.
  89
  90         (error-catching-loop thunk): discard trailing junk after a (quit).
  91
  92 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  93
  94         * boot-9.scm: Removed the old printer code.
  95
  96         * r4rs.scm (apply, call-with-current-continuation): Added comment
  97         explaining why apply and call/cc need to be closures.
  98
  99         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 100         Removed. These definitions are already present in r4rs.scm.
 101
 102         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 103         stack before printing traced frames; Re-enable trace flag at end
 104         of handlers.
 105
 106 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 107
 108         * debug.scm: Add hook for reset of trace level at abort.
 109
 110         * boot-9.scm (run-hooks): New procedure.
 111         (add-hooks!): New macro.
 112         Change hooks to use these functions.
 113
 114 *       * debug.scm: *Warning* This feature is a bit premature.  I add
 115         it anyway because 1. it is very useful, and, 2. you can start
 116         making it less premature by complaining to me and by modifying
 117         the source! :-)
 118         (trace): Given one or more procedure objects, trace each one.
 119         Given no arguments, show all traced procedures.
 120         (untrace): Given one or more procedure objects, untrace each one.
 121         Given no arguments, untrace all traced procedures.  The tracing in
 122         Guile have an advantage to most other systems: We don't create new
 123         procedure objects, but mark the procedure objects themselves.
 124         This means that also anonymous and internal procedures can be
 125         traced.
 126
 127         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 128         and exit-frame exceptions.
 129
 130 *       * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 131         (set-repl-prompt!): Setter for repl prompt.
 132         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 133         string, display it; if prompt is a thunk, call it and display its
 134         result; otherwise display "> ".
 135         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 136
 137         * r4rs.scm (%load-verbosely): Reverted change to
 138         `module-defined?', since the module system isn't bootstrapped when
 139         we load r4rs.scm.  This is just a temporary fix to make the
 140         repository version runnable.
 141
 142 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 143
 144         * boot-9.scm: Removed the enabling of debug evaluator and
 145         recording of source code positions.  This was placed there for our
 146         convenience, but it has already sneaked into the distribution
 147         once... so we'd better add this in our local copies instead when
 148         we need it.  (These options are normally enabled at the end of
 149         boot-9.scm when loading the debug module.)
 150
 151 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 152
 153         * boot-9.scm (module-defined?): New function.
 154         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 155         and eval.
 156         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 157         "defined?".
 158         * slib.scm (defined?): New function to take the place of the
 159         builtin "defined?".  It allways examines the slib module.
 160
 161 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 162
 163         * configure.in: Added AM_MAINTAINER_MODE
 164
 165 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 166
 167         * boot-9.scm (read-sharp): define directly, don't go through a
 168         %read-sharp layer.
 169
 170 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 171
 172         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 173         uniform-vector-set1! which doesn't exist.
 174
 175 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 176
 177         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 178         backtrace.c.)
 179
 180 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 181
 182         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 183         read-line): new procedures, see libguile/ChangeLog.
 184
 185 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 186
 187         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 188
 189         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 190         init-dynamic-module, dynamic-maybe-call,
 191         find-and-link-dynamic-module, link-dynamic-module,
 192         try-module-dynamic-link, registered-modules): New definitions for
 193         dynamic linking of modules.
 194         (resolve-module): Try to dynamically link the requested module
 195         after failing to load it as Scheme code.
 196
 197 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 198
 199         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 200
 201 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 202
 203         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 204         that's what it is.
 205
 206         * lineio.scm (make-line-buffering-input-port): Properly test for
 207         the case of an empty buffer list.  The old code assumed that '()
 208         was false.
 209
 210 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 211
 212 *       * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 213         (use-modules <module name> ...) Put the the modules named by
 214         <module name> ... on the use list of the current module.
 215
 216 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 217
 218         * boot-9.scm (error-catching-loop): Remove message saying that
 219         typing "$" will put you in the debugger.  This isn't implemented
 220         yet.
 221
 222 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 223
 224         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 225         been fixed, so this function is superfluous.
 226         (transform-usage-lambda): Use delq!, not delq-all!.
 227
 228 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 229
 230         * boot-9.scm (resolve-module): New optional parameter that
 231         controls whether autoloading is attempted or not. Default is #t.
 232         (process-define-module): Don't autoload the defined module.
 233         (try-module-autoload): Don't autoload the directory modules.
 234
 235         * boot-9.scm (process-define-module): Ensure that the-scm-module
 236         is last in the `uses' list to allow shadowing builtin
 237         bindings. All :use-module options are added in the order they
 238         appear in the arguments but before anything already on the list
 239         (such as the-scm-module).
 240
 241 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 242
 243         * slib.scm (slib-parent-dir): throw error if #f returned from
 244         %search-load-path.
 245
 246 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 247
 248         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 249         * Makefile.am, aclocal.m4: New files.
 250         * configure.in: Updated for Automake.
 251
 252 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 253
 254         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 255         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 256         function, use it accordingly.
 257
 258 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 259
 260         It's an "eval closure", not an "eval thunk."  A thunk is a
 261         function of no arguments.
 262         * boot-9.scm (module-type): Rename module field.
 263         (make-module, eval-in-module, make-root-module,
 264         set-current-module): Uses changed.
 265         (module-eval-closure, set-module-eval-closure!,
 266         root-module-closure): Renamed from module-eval-thunk,
 267         set-module-eval-thunk!, root-module-thunk.
 268         (set-current-module): Change uses of *top-level-lookup-thunk* to
 269         *top-level-eval-closure*.
 270
 271 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 272
 273         * slib.scm (slib-parent-dir): Use string-length, not length.
 274         (Thanks to Bernard Urban.)
 275
 276 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 277
 278         * boot-9.scm: The debugging evaluator and recording of positions
 279         aren't enabled by default any longer (they are switched on in
 280         debug.scm).  But during development we want to have them also
 281         *inside* boot-9.scm.  Therefore, two lines are added at the
 282         beginning of boot-9.scm to enable these.
 283
 284         Call `provide' so that `records' are included among the
 285         `*features*'.
 286
 287         The scheme for saving the stack has been adjusted: save-stack is
 288         now commonly available for saving the stack.  Calling `save-stack'
 289         sets a flag `stack-saved?' which prevents overwriting the stack.
 290         `stack-saved?' is reset at `abort'.
 291
 292         Spelling correction: seperate --> separate.
 293
 294         Removed `:'s that had creeped into some comments.
 295
 296         The repl now doesn't print #<unspecified> results any longer
 297         If the user wants to see this, he can do
 298         (assert-repl-print-unspecified #t) in his startup file.
 299
 300         The user now gets a friendly message instead of a backtrace at
 301         error.
 302
 303         Added `before-read-hook'.
 304
 305         Load module (ice-9 emacs) if option `-e' was specified.
 306
 307         (provide): New function.
 308
 309         (error): Save stack at entry, so that Guile entrails won't show up
 310         in backtraces.
 311
 312         (backtrace): New function.
 313
 314         (save-stack): Can now take arbitrary number of stack narrowing
 315         specifier pairs.  The first specifier in a pair controls inner
 316         border, the second the outer border.  A number means cut that
 317         number of frames, a procedure object means cut until that object
 318         is found in operator position in a frame.
 319
 320         * debug.scm: Enable debugging evaluator and recording of positions
 321         by default.
 322
 323         * slib.scm (slib:load): Adapt to the new behavior of
 324         primitive-load: It doesn't any longer try both with and without
 325         ".scm" extension.  (We don't want to use %search-load-path here.)
 326
 327         (implementation-vicinity): New function.  slib requires it
 328
 329         (library-vicinity): Updated.
 330
 331         Load "require.scm" in the library-vicinity.
 332
 333         (install-require-vicinity, install-require-module): New functions.
 334
 335 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 336
 337         * boot-9.scm (load-from-path): New function.
 338
 339         * boot-9.scm (try-load, basic-try-load, try-load-module,
 340         try-load): Deleted.  I don't think they're being used.
 341
 342         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 343         so they'll get distributed.
 344
 345         Get Guile to be a little less chatty by default.  The new user
 346         should see as little clutter as possible.
 347         * r4rs.scm (%load-verbosely): Make this #f by default.
 348         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 349         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 350
 351         * r4rs.scm: New file.
 352         * boot-9.scm: Load r4rs.scm, first thing.
 353         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 354         open-output-file, open-io-file, close-input-port,
 355         close-output-port, close-io-port, call-with-input-file,
 356         call-with-output-file, with-input-from-port, with-output-to-port,
 357         with-error-to-port, with-input-from-file, with-output-to-file,
 358         with-error-to-file, with-input-from-string, with-output-to-string,
 359         with-error-to-string, the-eof-object): Definitions moved to
 360         r4rs.scm.  Not all of them are R4RS, but those that are use those
 361         that are not.
 362         (load, %load-verbosely, %load-announce): Moved, along with code to
 363         set %load-hook, to r4rs.scm.
 364
 365         * test.scm: New file.
 366
 367         * boot-9.scm (integer?): Definition deleted, in favor of the one
 368         present in libguile (which used to be called int?).  I have no
 369         idea why integer? didn't just call int? to begin with.
 370
 371         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 372         =?, >?, and >=? deleted; they're defined that way by libguile now.
 373
 374         * boot-9.scm (load): Simplified; primitive-load does most of this
 375         work now.
 376         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 377         call %load-announce.
 378
 379 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 380
 381         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 382         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 383         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 384         components.
 385         (file-is-directory?): use stat:type.
 386
 387 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 388
 389         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 390         that's now taken care of in libguile, and in a way compatible with
 391         SCSH (which this isn't).
 392
 393 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 394
 395         * boot-9.scm: Formatting tweaks.
 396
 397 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 398
 399         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 400         after-error-hook, before-backtrace-hook and after-backtrace-hook
 401         to the error handler.  E.g.: fancy emacs support could plug into
 402         these.
 403         (save-stack): New function.  The stack is now made differently
 404         depending on the stack id.  (The motivation is to make a better
 405         choice regarding what stack frames to present to the user.)
 406         (error-catching-loop): Stack handling code moved outside into
 407         save-stack.
 408
 409 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 410
 411         * Makefile.in (scm_files): add expect.scm.
 412
 413         * expect.scm: new file ported from guile-iii.
 414
 415         * boot-9.scm: remove handle-system-error, after moving the code into
 416         error-catching-loop.
 417         Don't set 'throw-handler-default property on error keys.
 418         Just interpret (almost) any throw with 4 args as an error throw.
 419         Delete some try-load stuff that was already commented out.
 420
 421         Second thoughts, keep handle-system-error but call it from
 422         error-catching-loop.
 423
 424 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 425
 426         * boot-9.scm: Doc fixes.
 427         (make-module): Rework for readability.
 428         (make-root-module, make-scm-module): USES argument to make-module
 429         should be '(), not #f.
 430
 431         * boot-9.scm (try-load): %sys-load-path has been renamed to
 432         primitive-load-path; adjust call here.
 433
 434 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 435
 436         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 437         the stack to the correct place: when it is decided to generate an
 438         error-signal.
 439
 440 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 441
 442         * boot-9.scm (error-catching-loop, signal-handler,
 443         handle-system-error): Backtracing now works for signals aswell;
 444         Backtracing mechanism can now identify the stack root created by
 445         start-stack so that the user isn't exposed to system stack frames.
 446
 447 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 448
 449         * Makefile.in: Added threads.scm.
 450
 451 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 452
 453         * debug.scm (make-enable, make-disable): Simplified.
 454
 455         * boot-9.scm: Renamed %%throw-handler-default -->
 456         throw-handler-default.
 457         ((handle-system-error key . arg-list)): Changed the way errors are
 458         reported.
 459         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 460         acro.
 461         ((error-catching-loop thunk)): Introduce a lazy-catch into
 462         error-catching-loop so that the stack can be captured.
 463
 464 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 465
 466         * mapping.scm (hash-table-mapping): Explicitly request that
 467         make-vector fill new vectors with '(); this will make it easier to
 468         port Guile Scheme code to other Schemes.
 469         * boot-9.scm (make-print-style, make-print-table): Same.
 470
 471 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 472
 473         * boot-9.scm (load): rewritten again.
 474         Append "." to the default %load-path.
 475         (feature?): new function: checks for a symbol in the features list.
 476         (module-local-variable): remove apparently useless (caddr (list m v
 477         ...))
 478         (%load-announce): minor formatting change.
 479         (file-exists?): use access? if posix is featured.
 480         (file-is-directory?): use stat if i/o-extensions is featured.
 481         (try-module-autoload module-name): use file-exists? before
 482         file-is-directory?
 483
 484 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 485
 486         * boot-9.scm: Added conditional loading of threads.scm.
 487
 488         * threads.scm: New file.  Modified from the Cygnus-r0.3
 489         distribution.
 490
 491         * boot-9.scm (error-catching-loop): Added handling of key
 492         `switch-repl'.
 493
 494         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 495
 496 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 497
 498         * boot-9.scm (make-record-type, record-constructor): Don't assume
 499         the empty list is false when parsing the argument list.
 500
 501 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 502
 503         * boot-9.scm (signal-handler): Clean up logic.
 504
 505         * boot-9.scm (load): Assume %load-path is always bound.
 506
 507 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 508
 509         * boot-9.scm (error): replace another throw with scm-error.  Throw
 510         to 'misc-error instead of 'error (no need to distinguish these.)
 511         Don't set up 'error as a key.
 512         Set up regex-error as a key, if regex is available.
 513         (signal-handler): use scm-error, not throw.
 514
 515         (%try-load, try-load-with-path, %load, load-with-path,
 516         basic-try-load-with-path, basic-load-with-path,
 517         try-load-module-with-path,load-module-with-path): deleted, since
 518         they seem redundant.
 519         (try-load): define using %try-load, not try-load-with-path.
 520         (load): rewritten.  load tries to open the file directly and
 521         with a .scm extension before searching the library directories
 522         (should "." be added to %load-path?  then load could still open
 523         directly files starting with "/").
 524         (try-module-autoload): use load, not load-with-path.
 525         (%load-indent): deleted, -2 was causing errors.
 526
 527         (%read-sharp): use port-line, not line-number.
 528
 529 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 530
 531         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 532         straightforward to provide the equivalent functionality using
 533         (catch #t ...), so there's no need for the extra complexity.  2)
 534         Outside the context of a read-eval-print loop (which Guile should
 535         not require) it's not clear we should do anything more complicated
 536         than print an error and exit; the user or REPL can establish
 537         something better if it wants.  3) In that case, it's much more
 538         robust to just do it in the C code.
 539
 540 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 541
 542         * boot-9.scm (%try-load): define using primitive-load.  Previously
 543         %try-load itself was the primitive.
 544         (load-with-path): use scm-error instead of %load-announce-lossage.
 545         Errors are thrown to 'misc-error instead of 'could-not-load.
 546         (%load-announce-lossage): deleted.
 547
 548 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 549
 550         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 551         (make-record-type type-name fields): Temporarily remove support
 552         for printing of records (not possible yet with C printer).
 553
 554 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 555
 556         * boot-9.scm (file-exists?, file-is-directory): catch only
 557         system-error, not every kind of error.
 558         (scm-error): new procedure.
 559
 560 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 561
 562         * boot-9.scm: Formatting tweaks.
 563
 564 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 565
 566         * boot-9.scm (%%handle-system-error key): remove the code for
 567         SCM-style errors.  handle the case that an unexpected number
 568         of args are supplied.
 569         (%%system-errors): removed.
 570         (error): redefine using a throw with key and 4 args.
 571         ('error): associate 'error, 'error-signal keys with
 572         %%handle-system-error.
 573         (%%default-error-handler): removed.
 574         (signal-handler): throw with 4 args and use the error-signal key.
 575         Create an error message instead of using numerical codes.
 576         (%%bad-throw): call error instead of throw if key not found.
 577
 578 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 579
 580         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 581         (%%handle-system-error key): check subr is not #f before printing.
 582         Recognize %s (embed an argument using "display") and
 583         %S (embed an argument using "write").
 584
 585 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 586
 587         * boot-9.scm (%%handle-system-error key): set args and rest to
 588         the empty list if they are #f.
 589         Initialize out-of-range as an error key.
 590
 591 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 592
 593         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 594
 595         * boot-9.scm: remove leading %% from references to '%%system-error.
 596         (%%handle-system-error): don't pass all the thrown arguments when
 597         aborting, just the key and subr.
 598         Remove the code to "Install default handlers for built-in errors."
 599         Remove the definition of the syserror procedure.
 600         Associate 'numerical-overflow with default handler.
 601
 602 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 603
 604         * boot-9.scm: Name change: value-ref --> local-ref
 605         resolved-ref --> nested-ref  Motivation: conformance to the other
 606         dictionary operators: list-ref operates on list, vector-ref
 607         operates on vector, nested-ref operates on nested namespace,
 608         local-ref operates on the local nested namespace.
 609
 610 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 611
 612         * boot-9.scm (%%handle-system-error): recognise errors thrown
 613         by lgh-error (fill-message etc.)
 614         (fill-message): check first whether args is null.
 615         (fill-message): bug fix and check that args is a list.
 616
 617 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
 618
 619         * boot-9.scm: %load-path is initialized in C code now.
 620         (implementation-vicinity, parse-path): Deleted, along with code to
 621         initialize %load-path.
 622
 623         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 624         "/", use one to separate it from the file.
 625
 626 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 627
 628         * boot-9.scm (%load-path): Add the site directory.
 629         Add the directory named after the version number.
 630         Prepend the version number to the other directories in the path.
 631         Simplify by mapping the common prefix onto each item.
 632         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
 633         sitedatadir): New definitions.
 634         (libparent, libdir, install_path): Replaced by above.
 635         (install): Create the above directories.
 636         Put the source files into subpkgdatadir.
 637         (uninstall): Remove the above directories.
 638
 639 Thu Aug 29 21:48:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 640
 641         Don't use the PLUGIN system to gather information for the
 642         Makefile's distribution and installation targets; just put it all
 643         in the Makefile directly.
 644         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 645         for these.
 646         * configure.in: Remove code that gets and substitutes scm_files and
 647         aux_files.
 648         * Makefile.in (scm_files, aux_files): Write out the list of files
 649         here, where people expect to find them.
 650
 651 Fri Aug 23 06:44:36 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 652
 653         * boot-9.scm: Preliminary solution: optionally load the debug
 654         module.  Changed "gls" to "guile1.0b3".
 655
 656         * debug.scm: New file: debug extensions.
 657
 658 Wed Aug 21 13:06:56 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 659
 660         * boot-9.scm (print-vector): Renamed weak-hash-table? -->
 661         weak-key-hash-table?.  (Again!)
 662
 663 Tue Aug 20 07:31:39 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 664
 665         * boot-9.scm (print-vector, macro-table, xformer-table):
 666         Renamed weak-hash-table --> weak-key-hash-table.
 667
 668         * poe.scm (funcq-memo): Renamed weak-hash-table -->
 669         weak-key-hash-table.

 673         * boot-9.scm (*null-device*): global constant from goonix.
 674         (move->fdes): adjusted for boolean primitive-move->fdes.  return
 675         the modified port, always set revealed count to 1 (SCSH compatible).
 676         (release-port-handle port): from goonix (SCSH compatible).
 677         (%open-file): removed.
 678         (open-input-file, open-output-file, file-exists?, file-is-directory?):
 679         modified for open-file change (does not return #f).
 680
 681 Thu Aug  1 02:52:42 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 682
 683         * Makefile.in (dist-dir): New target for new dist system.
 684         (manifest): Deleted.
 685         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
 686         directory, and needs special treatment in the dist-dir target.
 687
 688 Thu Aug  1 09:00:21 1996  Gary Houston  <ghouston@actrix.gen.nz>
 689
 690         * boot-9.scm: remove the wrappers for '%' system primitives,
 691         now that they throw errors directly.
 692         remove make-simple-wrapper and similar functions.
 693         protect a call to getenv which may now throw an exception.
 694
 695 Wed Jul 31 23:44:42 1996  Gary Houston  <ghouston@actrix.gen.nz>
 696
 697         * boot-9.scm (false-if-exception): new macro.
 698
 699 Fri Apr 19 13:53:08 1996  Tom Lord  <lord@beehive>
 700
 701         * The more things change...
