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

 131
 132         * boot-9.scm (eval-string, command-line, load-user-init): New
 133         functions.
 134
 135 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 136
 137         * boot-9.scm (log10): defined.
 138
 139 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 140
 141         * expect.scm (expect-select): correct the millisecond timeout
 142         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 143
 144 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 145
 146         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 147         instead of in libguile.
 148         (tm:sec etc.) new accessors for broken-down time.
 149         (set-tm:sec etc.) new setters for broken-down time.
 150
 151 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 152
 153         * boot-9.scm (netent:addrtype, servent:port): added missing
 154         procedures.
 155         (netent:net, servent:proto): repaired.
 156         (utsname:sysname etc.): new accessors for uname.
 157
 158 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 159
 160         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 161         sockaddr:port): new functions.
 162
 163 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 164
 165         * boot-9.scm: define accessor procedures for the objects returned
 166         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 167         passwd:name, where the first component is the name of the C structure
 168         and the second is the unprefixed C member name.)
 169
 170 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 171
 172         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 173         setservent): no longer take an argument, it was bogus.
 174
 175 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 176
 177         * boot-9.scm (scm-error): deleted, reimplemented in C.
 178
 179 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 180
 181         * boot-9.scm (process-define-module): Modified to handle both
 182         keywords and symbols.
 183
 184 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 185
 186         * slib.scm: update read usage.
 187
 188         * r4rs.scm: update primitive-load usage.
 189         Don't define read-sharp.
 190
 191         * boot-9.scm: use read-hash-extend to install extra read syntax.
 192         (read-sharp): removed.
 193         Adjust usage of primitive-load-path, read, which no longer take
 194         case_i or read-sharp arguments.
 195
 196 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 197
 198         * boot-9.scm: Added loading of session support module.
 199
 200         * debug.scm: Removed `display-application'.  (Replaced by
 201         primitive procedure.)
 202
 203         * boot-9.scm (beautify-user-module!): Don't add the root module
 204         interface to the end of the use-list of the root module.
 205
 206 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 207
 208         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 209
 210 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 211
 212         * boot-9.scm: check use-emacs-interface for emacs support.
 213
 214 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 215
 216         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 217         read gets EOF.
 218         * (exit): alias for quit.
 219
 220 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 221
 222         * boot-9.scm (error-catching-loop thunk): use a status variable to
 223         return the quit args.
 224         (scm-style-repl): call -quit, passing return value from
 225         error-catching-repl.  Make -quit return its args.
 226         stand-alone-repl: comment out, since it seems unused.
 227
 228         (error-catching-loop thunk): discard trailing junk after a (quit).
 229
 230 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 231
 232         * boot-9.scm: Removed the old printer code.
 233
 234         * r4rs.scm (apply, call-with-current-continuation): Added comment
 235         explaining why apply and call/cc need to be closures.
 236
 237         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 238         Removed. These definitions are already present in r4rs.scm.
 239
 240         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 241         stack before printing traced frames; Re-enable trace flag at end
 242         of handlers.
 243
 244 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 245
 246         * debug.scm: Add hook for reset of trace level at abort.
 247
 248         * boot-9.scm (run-hooks): New procedure.
 249         (add-hooks!): New macro.
 250         Change hooks to use these functions.
 251
 252         * debug.scm: *Warning* This feature is a bit premature.  I add
 253         it anyway because 1. it is very useful, and, 2. you can start
 254         making it less premature by complaining to me and by modifying
 255         the source! :-)
 256         (trace): Given one or more procedure objects, trace each one.
 257         Given no arguments, show all traced procedures.
 258         (untrace): Given one or more procedure objects, untrace each one.
 259         Given no arguments, untrace all traced procedures.  The tracing in
 260         Guile have an advantage to most other systems: We don't create new
 261         procedure objects, but mark the procedure objects themselves.
 262         This means that also anonymous and internal procedures can be
 263         traced.
 264
 265         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 266         and exit-frame exceptions.
 267
 268         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 269         (set-repl-prompt!): Setter for repl prompt.
 270         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 271         string, display it; if prompt is a thunk, call it and display its
 272         result; otherwise display "> ".
 273         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 274
 275         * r4rs.scm (%load-verbosely): Reverted change to
 276         `module-defined?', since the module system isn't bootstrapped when
 277         we load r4rs.scm.  This is just a temporary fix to make the
 278         repository version runnable.
 279
 280 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 281
 282         * boot-9.scm: Removed the enabling of debug evaluator and
 283         recording of source code positions.  This was placed there for our
 284         convenience, but it has already sneaked into the distribution
 285         once... so we'd better add this in our local copies instead when
 286         we need it.  (These options are normally enabled at the end of
 287         boot-9.scm when loading the debug module.)
 288
 289 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 290
 291         * boot-9.scm (module-defined?): New function.
 292         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 293         and eval.
 294         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 295         "defined?".
 296         * slib.scm (defined?): New function to take the place of the
 297         builtin "defined?".  It allways examines the slib module.
 298
 299 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 300
 301         * configure.in: Added AM_MAINTAINER_MODE
 302
 303 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 304
 305         * boot-9.scm (read-sharp): define directly, don't go through a
 306         %read-sharp layer.
 307
 308 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 309
 310         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 311         uniform-vector-set1! which doesn't exist.
 312
 313 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 314
 315         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 316         backtrace.c.)
 317
 318 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 319
 320         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 321         read-line): new procedures, see libguile/ChangeLog.
 322
 323 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 324
 325         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 326
 327         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 328         init-dynamic-module, dynamic-maybe-call,
 329         find-and-link-dynamic-module, link-dynamic-module,
 330         try-module-dynamic-link, registered-modules): New definitions for
 331         dynamic linking of modules.
 332         (resolve-module): Try to dynamically link the requested module
 333         after failing to load it as Scheme code.
 334
 335 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 336
 337         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 338
 339 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 340
 341         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 342         that's what it is.
 343
 344         * lineio.scm (make-line-buffering-input-port): Properly test for
 345         the case of an empty buffer list.  The old code assumed that '()
 346         was false.
 347
 348 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 349
 350         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 351         (use-modules <module name> ...) Put the the modules named by
 352         <module name> ... on the use list of the current module.
 353
 354 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 355
 356         * boot-9.scm (error-catching-loop): Remove message saying that
 357         typing "$" will put you in the debugger.  This isn't implemented
 358         yet.
 359
 360 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 361
 362         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 363         been fixed, so this function is superfluous.
 364         (transform-usage-lambda): Use delq!, not delq-all!.
 365
 366 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 367
 368         * boot-9.scm (resolve-module): New optional parameter that
 369         controls whether autoloading is attempted or not. Default is #t.
 370         (process-define-module): Don't autoload the defined module.
 371         (try-module-autoload): Don't autoload the directory modules.
 372
 373         * boot-9.scm (process-define-module): Ensure that the-scm-module
 374         is last in the `uses' list to allow shadowing builtin
 375         bindings. All :use-module options are added in the order they
 376         appear in the arguments but before anything already on the list
 377         (such as the-scm-module).
 378
 379 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 380
 381         * slib.scm (slib-parent-dir): throw error if #f returned from
 382         %search-load-path.
 383
 384 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 385
 386         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 387         * Makefile.am, aclocal.m4: New files.
 388         * configure.in: Updated for Automake.
 389
 390 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 391
 392         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 393         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 394         function, use it accordingly.
 395
 396 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 397
 398         It's an "eval closure", not an "eval thunk."  A thunk is a
 399         function of no arguments.
 400         * boot-9.scm (module-type): Rename module field.
 401         (make-module, eval-in-module, make-root-module,
 402         set-current-module): Uses changed.
 403         (module-eval-closure, set-module-eval-closure!,
 404         root-module-closure): Renamed from module-eval-thunk,
 405         set-module-eval-thunk!, root-module-thunk.
 406         (set-current-module): Change uses of *top-level-lookup-thunk* to
 407         *top-level-eval-closure*.
 408
 409 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 410
 411         * slib.scm (slib-parent-dir): Use string-length, not length.
 412         (Thanks to Bernard Urban.)
 413
 414 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 415
 416         * boot-9.scm: The debugging evaluator and recording of positions
 417         aren't enabled by default any longer (they are switched on in
 418         debug.scm).  But during development we want to have them also
 419         *inside* boot-9.scm.  Therefore, two lines are added at the
 420         beginning of boot-9.scm to enable these.
 421
 422         Call `provide' so that `records' are included among the
 423         `*features*'.
 424
 425         The scheme for saving the stack has been adjusted: save-stack is
 426         now commonly available for saving the stack.  Calling `save-stack'
 427         sets a flag `stack-saved?' which prevents overwriting the stack.
 428         `stack-saved?' is reset at `abort'.
 429
 430         Spelling correction: seperate --> separate.
 431
 432         Removed `:'s that had creeped into some comments.
 433
 434         The repl now doesn't print #<unspecified> results any longer
 435         If the user wants to see this, he can do
 436         (assert-repl-print-unspecified #t) in his startup file.
 437
 438         The user now gets a friendly message instead of a backtrace at
 439         error.
 440
 441         Added `before-read-hook'.
 442
 443         Load module (ice-9 emacs) if option `-e' was specified.
 444
 445         (provide): New function.
 446
 447         (error): Save stack at entry, so that Guile entrails won't show up
 448         in backtraces.
 449
 450         (backtrace): New function.
 451
 452         (save-stack): Can now take arbitrary number of stack narrowing
 453         specifier pairs.  The first specifier in a pair controls inner
 454         border, the second the outer border.  A number means cut that
 455         number of frames, a procedure object means cut until that object
 456         is found in operator position in a frame.
 457
 458         * debug.scm: Enable debugging evaluator and recording of positions
 459         by default.
 460
 461         * slib.scm (slib:load): Adapt to the new behavior of
 462         primitive-load: It doesn't any longer try both with and without
 463         ".scm" extension.  (We don't want to use %search-load-path here.)
 464
 465         (implementation-vicinity): New function.  slib requires it
 466
 467         (library-vicinity): Updated.
 468
 469         Load "require.scm" in the library-vicinity.
 470
 471         (install-require-vicinity, install-require-module): New functions.
 472
 473 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 474
 475         * boot-9.scm (load-from-path): New function.
 476
 477         * boot-9.scm (try-load, basic-try-load, try-load-module,
 478         try-load): Deleted.  I don't think they're being used.
 479
 480         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 481         so they'll get distributed.
 482
 483         Get Guile to be a little less chatty by default.  The new user
 484         should see as little clutter as possible.
 485         * r4rs.scm (%load-verbosely): Make this #f by default.
 486         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 487         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 488
 489         * r4rs.scm: New file.
 490         * boot-9.scm: Load r4rs.scm, first thing.
 491         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 492         open-output-file, open-io-file, close-input-port,
 493         close-output-port, close-io-port, call-with-input-file,
 494         call-with-output-file, with-input-from-port, with-output-to-port,
 495         with-error-to-port, with-input-from-file, with-output-to-file,
 496         with-error-to-file, with-input-from-string, with-output-to-string,
 497         with-error-to-string, the-eof-object): Definitions moved to
 498         r4rs.scm.  Not all of them are R4RS, but those that are use those
 499         that are not.
 500         (load, %load-verbosely, %load-announce): Moved, along with code to
 501         set %load-hook, to r4rs.scm.
 502
 503         * test.scm: New file.
 504
 505         * boot-9.scm (integer?): Definition deleted, in favor of the one
 506         present in libguile (which used to be called int?).  I have no
 507         idea why integer? didn't just call int? to begin with.
 508
 509         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 510         =?, >?, and >=? deleted; they're defined that way by libguile now.
 511
 512         * boot-9.scm (load): Simplified; primitive-load does most of this
 513         work now.
 514         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 515         call %load-announce.
 516
 517 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 518
 519         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 520         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 521         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 522         components.
 523         (file-is-directory?): use stat:type.
 524
 525 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 526
 527         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 528         that's now taken care of in libguile, and in a way compatible with
 529         SCSH (which this isn't).
 530
 531 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 532
 533         * boot-9.scm: Formatting tweaks.
 534
 535 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 536
 537         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 538         after-error-hook, before-backtrace-hook and after-backtrace-hook
 539         to the error handler.  E.g.: fancy emacs support could plug into
 540         these.
 541         (save-stack): New function.  The stack is now made differently
 542         depending on the stack id.  (The motivation is to make a better
 543         choice regarding what stack frames to present to the user.)
 544         (error-catching-loop): Stack handling code moved outside into
 545         save-stack.
 546
 547 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 548
 549         * Makefile.in (scm_files): add expect.scm.
 550
 551         * expect.scm: new file ported from guile-iii.
 552
 553         * boot-9.scm: remove handle-system-error, after moving the code into
 554         error-catching-loop.
 555         Don't set 'throw-handler-default property on error keys.
 556         Just interpret (almost) any throw with 4 args as an error throw.
 557         Delete some try-load stuff that was already commented out.
 558
 559         Second thoughts, keep handle-system-error but call it from
 560         error-catching-loop.
 561
 562 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 563
 564         * boot-9.scm: Doc fixes.
 565         (make-module): Rework for readability.
 566         (make-root-module, make-scm-module): USES argument to make-module
 567         should be '(), not #f.
 568
 569         * boot-9.scm (try-load): %sys-load-path has been renamed to
 570         primitive-load-path; adjust call here.
 571
 572 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 573
 574         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 575         the stack to the correct place: when it is decided to generate an
 576         error-signal.
 577
 578 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 579
 580         * boot-9.scm (error-catching-loop, signal-handler,
 581         handle-system-error): Backtracing now works for signals aswell;
 582         Backtracing mechanism can now identify the stack root created by
 583         start-stack so that the user isn't exposed to system stack frames.
 584
 585 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 586
 587         * Makefile.in: Added threads.scm.
 588
 589 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 590
 591         * debug.scm (make-enable, make-disable): Simplified.
 592
 593         * boot-9.scm: Renamed %%throw-handler-default -->
 594         throw-handler-default.
 595         ((handle-system-error key . arg-list)): Changed the way errors are
 596         reported.
 597         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 598         acro.
 599         ((error-catching-loop thunk)): Introduce a lazy-catch into
 600         error-catching-loop so that the stack can be captured.
 601
 602 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 603
 604         * mapping.scm (hash-table-mapping): Explicitly request that
 605         make-vector fill new vectors with '(); this will make it easier to
 606         port Guile Scheme code to other Schemes.
 607         * boot-9.scm (make-print-style, make-print-table): Same.
 608
 609 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 610
 611         * boot-9.scm (load): rewritten again.
 612         Append "." to the default %load-path.
 613         (feature?): new function: checks for a symbol in the features list.
 614         (module-local-variable): remove apparently useless (caddr (list m v
 615         ...))
 616         (%load-announce): minor formatting change.
 617         (file-exists?): use access? if posix is featured.
 618         (file-is-directory?): use stat if i/o-extensions is featured.
 619         (try-module-autoload module-name): use file-exists? before
 620         file-is-directory?
 621
 622 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 623
 624         * boot-9.scm: Added conditional loading of threads.scm.
 625
 626         * threads.scm: New file.  Modified from the Cygnus-r0.3
 627         distribution.
 628
 629         * boot-9.scm (error-catching-loop): Added handling of key
 630         `switch-repl'.
 631
 632         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 633
 634 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 635
 636         * boot-9.scm (make-record-type, record-constructor): Don't assume
 637         the empty list is false when parsing the argument list.
 638
 639 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 640
 641         * boot-9.scm (signal-handler): Clean up logic.
 642
 643         * boot-9.scm (load): Assume %load-path is always bound.
 644
 645 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 646
 647         * boot-9.scm (error): replace another throw with scm-error.  Throw
 648         to 'misc-error instead of 'error (no need to distinguish these.)
 649         Don't set up 'error as a key.
 650         Set up regex-error as a key, if regex is available.
 651         (signal-handler): use scm-error, not throw.
 652
 653         (%try-load, try-load-with-path, %load, load-with-path,
 654         basic-try-load-with-path, basic-load-with-path,
 655         try-load-module-with-path,load-module-with-path): deleted, since
 656         they seem redundant.
 657         (try-load): define using %try-load, not try-load-with-path.
 658         (load): rewritten.  load tries to open the file directly and
 659         with a .scm extension before searching the library directories
 660         (should "." be added to %load-path?  then load could still open
 661         directly files starting with "/").
 662         (try-module-autoload): use load, not load-with-path.
 663         (%load-indent): deleted, -2 was causing errors.
 664
 665         (%read-sharp): use port-line, not line-number.
 666
 667 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 668
 669         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 670         straightforward to provide the equivalent functionality using
 671         (catch #t ...), so there's no need for the extra complexity.  2)
 672         Outside the context of a read-eval-print loop (which Guile should
 673         not require) it's not clear we should do anything more complicated
 674         than print an error and exit; the user or REPL can establish
 675         something better if it wants.  3) In that case, it's much more
 676         robust to just do it in the C code.
 677
 678 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 679
 680         * boot-9.scm (%try-load): define using primitive-load.  Previously
 681         %try-load itself was the primitive.
 682         (load-with-path): use scm-error instead of %load-announce-lossage.
 683         Errors are thrown to 'misc-error instead of 'could-not-load.
 684         (%load-announce-lossage): deleted.
 685
 686 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 687
 688         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 689         (make-record-type type-name fields): Temporarily remove support
 690         for printing of records (not possible yet with C printer).
 691
 692 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 693
 694         * boot-9.scm (file-exists?, file-is-directory): catch only
 695         system-error, not every kind of error.
 696         (scm-error): new procedure.
 697
 698 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 699
 700         * boot-9.scm: Formatting tweaks.
 701
 702 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 703
 704         * boot-9.scm (%%handle-system-error key): remove the code for
 705         SCM-style errors.  handle the case that an unexpected number
 706         of args are supplied.
 707         (%%system-errors): removed.
 708         (error): redefine using a throw with key and 4 args.
 709         ('error): associate 'error, 'error-signal keys with
 710         %%handle-system-error.
 711         (%%default-error-handler): removed.
 712         (signal-handler): throw with 4 args and use the error-signal key.
 713         Create an error message instead of using numerical codes.
 714         (%%bad-throw): call error instead of throw if key not found.
 715

 741
 742         * boot-9.scm: Name change: value-ref --> local-ref
 743         resolved-ref --> nested-ref  Motivation: conformance to the other
 744         dictionary operators: list-ref operates on list, vector-ref
 745         operates on vector, nested-ref operates on nested namespace,
 746         local-ref operates on the local nested namespace.
