ice-9/ChangeLog

   1 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
   2
   3         * slib.scm (slib:warn): Alias for WARN function.
   4
   5 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
   6
   7         * boot-9.scm (struct-printer): Fix off-by-one error in range
   8         check.  Correctly check for struct printer tag.
   9
  10         * expect.scm: Turn this into a module, (ice-9 expect).
  11         (expect-port, expect-timeout, expect-timeout-proc,
  12         expect-eof-proc, expect-char-proc, expect, expect-strings,
  13         expect-select): Make these public definitions.
  14         (expect-strings): Use make-regexp and regexp-exec, instead of
  15         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
  16         that's okay.
  17
  18         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
  19         users in the core, and relies on mildly hairy details of the old
  20         regexp interface.
  21
  22         * test.scm: Re-enable tests asserting that '() is true, and not a
  23         boolean.  This stuff has been true for a while.
  24
  25         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
  26         function names.
  27
  28         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
  29         fixes.
  30
  31 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
  32
  33         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
  34         ../configure.in.
  35
  36 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  37
  38         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
  39         vtable and not the one of the struct.
  40
  41 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  42
  43         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
  44         make-struct-printer, set-struct-printer-in-vtable!): New bindings
  45         to support printing of structures.
  46         (record-type-vtable, make-record-type): Add slot to hold printing
  47         function and initialize it with something appropriate.  Removed
  48         commented out printing code.
  49         (record-type-name, record-type-fields): Adjusted slot offsets.
  50         (%print-module): Reduce argument list to "mod" and "port".
  51
  52 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  53
  54         * slib.scm (identity): New function, used by SLIB.
  55
  56 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
  57
  58         * boot-9.scm: signal-handler, alarm-thunk: removed.
  59         don't define ticks-interrupt etc.
  60         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
  61         during call to scm-style-repl.
  62
  63 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
  64
  65         * slib.scm (slib:load): Use primitive-load-path instead of
  66         basic-load.  This is probably wrong, but hopefully the entire
  67         source access system will be revised soon anyway, and this will
  68         make require behave more like Emacs Lisp's require.  If this
  69         breaks something, please let me know.  Maybe this is real dumb.
  70
  71 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
  72
  73         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
  74         * boot-9.scm: If the `regex' feature is present, use the module
  75         (ice-9 regex).
  76
  77 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
  78
  79         * regex.scm: New file.
  80         * Makefile.am (subpkgdata_DATA): Add regex.scm.
  81         * Makefile.in: Regenerated.
  82
  83 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  84
  85         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
  86         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
  87         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
  88         threads.scm: New address for FSF.
  89
  90 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
  91
  92         * debug.scm: Update copyright years; this file has been worked on
  93         in 1997.
  94
  95 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
  96
  97         * expect.scm: use gettimeofday instead of get-internal-real-time
  98         and use a floating point timeout when calling select.  Untested,
  99         since the regex library is currently AWOL.
 100
 101 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
 102
 103         * boot-9.scm (eval-string): Function deleted; it was already
 104         implemented in C, so there's no point in making a divergable copy
 105         here.
 106
 107 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 108
 109         * Makefile.in: Regenerated, using automake-1.1p.
 110
 111 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 112
 113         * Makefile.in: Regenerated, using automake-1.1p.
 114
 115 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 116
 117         * boot-9.scm (error-catching-loop): don't read a line from
 118         current input when quit is encountered, the previous change
 119         fixes this too.
 120
 121 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
 122
 123         * boot-9.scm (scm-style-repl): After reading an expression,
 124         consume any trailing newline (perhaps preceded by whitespace), to
 125         avoid screwing up GDB.  More detail in comments.
 126
 127 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
 128
 129         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
 130         the Scheme code like code yet.
 131         * Makefile.in: Resrac,husrched.
 132
 133 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 134
 135         * boot-9.scm (link-dynamic-module): Do not catch errors from
 136         dynamic-link and dynamic-call.  When the shared library exists it
 137         is now assumed to be suitable for a dynamic C module.
 138
 139 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 140
 141         * boot-9.scm (process-use-modules): New function to support the
 142         use-modules macro
 143         (use-modules): throw an error iff one of the requested modules
 144         can't be found.
 145
 146 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 147
 148         * boot-9.scm: don't define timer-thunk or gc-thunk.
 149
 150 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 151
 152         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 153
 154         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 155         we're not using AM_INIT_GUILE_MODULE any more.
 156         * Makefile.in: Regeneratitetedrerd.
 157
 158 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 159
 160         Get 'make dist' to work again.
 161         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 162         * Makefile.in: Regenerated, like two tons of fleas.
 163
 164         Changes for reduced Guile distribution: one configure script,
 165         no plugins.
 166         * configure.in, configure: Removed.
 167         * Makefile.in: Regenerated.
 168
 169 Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>
 170
 171         * boot-9.scm (eval-string, command-line, load-user-init): New
 172         functions.
 173
 174 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 175
 176         * boot-9.scm (log10): defined.
 177
 178 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 179
 180         * expect.scm (expect-select): correct the millisecond timeout
 181         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 182
 183 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 184
 185         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 186         instead of in libguile.
 187         (tm:sec etc.) new accessors for broken-down time.
 188         (set-tm:sec etc.) new setters for broken-down time.
 189
 190 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 191
 192         * boot-9.scm (netent:addrtype, servent:port): added missing
 193         procedures.
 194         (netent:net, servent:proto): repaired.
 195         (utsname:sysname etc.): new accessors for uname.
 196
 197 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 198
 199         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 200         sockaddr:port): new functions.
 201
 202 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 203
 204         * boot-9.scm: define accessor procedures for the objects returned
 205         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 206         passwd:name, where the first component is the name of the C structure
 207         and the second is the unprefixed C member name.)
 208
 209 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 210
 211         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 212         setservent): no longer take an argument, it was bogus.
 213
 214 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 215
 216         * boot-9.scm (scm-error): deleted, reimplemented in C.
 217
 218 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 219
 220         * boot-9.scm (process-define-module): Modified to handle both
 221         keywords and symbols.
 222
 223 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 224
 225         * slib.scm: update read usage.
 226
 227         * r4rs.scm: update primitive-load usage.
 228         Don't define read-sharp.
 229
 230         * boot-9.scm: use read-hash-extend to install extra read syntax.
 231         (read-sharp): removed.
 232         Adjust usage of primitive-load-path, read, which no longer take
 233         case_i or read-sharp arguments.
 234
 235 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 236
 237         * boot-9.scm: Added loading of session support module.
 238
 239         * debug.scm: Removed `display-application'.  (Replaced by
 240         primitive procedure.)
 241
 242         * boot-9.scm (beautify-user-module!): Don't add the root module
 243         interface to the end of the use-list of the root module.
 244
 245 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 246
 247         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 248
 249 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 250
 251         * boot-9.scm: check use-emacs-interface for emacs support.
 252
 253 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 254
 255         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 256         read gets EOF.
 257         * (exit): alias for quit.
 258
 259 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 260
 261         * boot-9.scm (error-catching-loop thunk): use a status variable to
 262         return the quit args.
 263         (scm-style-repl): call -quit, passing return value from
 264         error-catching-repl.  Make -quit return its args.
 265         stand-alone-repl: comment out, since it seems unused.
 266
 267         (error-catching-loop thunk): discard trailing junk after a (quit).
 268
 269 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 270
 271         * boot-9.scm: Removed the old printer code.
 272
 273         * r4rs.scm (apply, call-with-current-continuation): Added comment
 274         explaining why apply and call/cc need to be closures.
 275
 276         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 277         Removed. These definitions are already present in r4rs.scm.
 278
 279         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 280         stack before printing traced frames; Re-enable trace flag at end
 281         of handlers.
 282
 283 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 284
 285         * debug.scm: Add hook for reset of trace level at abort.
 286
 287         * boot-9.scm (run-hooks): New procedure.
 288         (add-hooks!): New macro.
 289         Change hooks to use these functions.
 290
 291         * debug.scm: *Warning* This feature is a bit premature.  I add
 292         it anyway because 1. it is very useful, and, 2. you can start
 293         making it less premature by complaining to me and by modifying
 294         the source! :-)
 295         (trace): Given one or more procedure objects, trace each one.
 296         Given no arguments, show all traced procedures.
 297         (untrace): Given one or more procedure objects, untrace each one.
 298         Given no arguments, untrace all traced procedures.  The tracing in
 299         Guile have an advantage to most other systems: We don't create new
 300         procedure objects, but mark the procedure objects themselves.
 301         This means that also anonymous and internal procedures can be
 302         traced.
 303
 304         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 305         and exit-frame exceptions.
 306
 307         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 308         (set-repl-prompt!): Setter for repl prompt.
 309         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 310         string, display it; if prompt is a thunk, call it and display its
 311         result; otherwise display "> ".
 312         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 313
 314         * r4rs.scm (%load-verbosely): Reverted change to
 315         `module-defined?', since the module system isn't bootstrapped when
 316         we load r4rs.scm.  This is just a temporary fix to make the
 317         repository version runnable.
 318
 319 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 320
 321         * boot-9.scm: Removed the enabling of debug evaluator and
 322         recording of source code positions.  This was placed there for our
 323         convenience, but it has already sneaked into the distribution
 324         once... so we'd better add this in our local copies instead when
 325         we need it.  (These options are normally enabled at the end of
 326         boot-9.scm when loading the debug module.)
 327
 328 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 329
 330         * boot-9.scm (module-defined?): New function.
 331         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 332         and eval.
 333         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 334         "defined?".
 335         * slib.scm (defined?): New function to take the place of the
 336         builtin "defined?".  It allways examines the slib module.
 337
 338 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 339
 340         * configure.in: Added AM_MAINTAINER_MODE
 341
 342 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 343
 344         * boot-9.scm (read-sharp): define directly, don't go through a
 345         %read-sharp layer.
 346
 347 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 348
 349         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 350         uniform-vector-set1! which doesn't exist.
 351
 352 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 353
 354         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 355         backtrace.c.)
 356
 357 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 358
 359         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 360         read-line): new procedures, see libguile/ChangeLog.
 361
 362 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 363
 364         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 365
 366         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 367         init-dynamic-module, dynamic-maybe-call,
 368         find-and-link-dynamic-module, link-dynamic-module,
 369         try-module-dynamic-link, registered-modules): New definitions for
 370         dynamic linking of modules.
 371         (resolve-module): Try to dynamically link the requested module
 372         after failing to load it as Scheme code.
 373
 374 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 375
 376         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 377
 378 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 379
 380         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 381         that's what it is.
 382
 383         * lineio.scm (make-line-buffering-input-port): Properly test for
 384         the case of an empty buffer list.  The old code assumed that '()
 385         was false.
 386
 387 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 388
 389         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 390         (use-modules <module name> ...) Put the the modules named by
 391         <module name> ... on the use list of the current module.
 392
 393 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 394
 395         * boot-9.scm (error-catching-loop): Remove message saying that
 396         typing "$" will put you in the debugger.  This isn't implemented
 397         yet.
 398
 399 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 400
 401         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 402         been fixed, so this function is superfluous.
 403         (transform-usage-lambda): Use delq!, not delq-all!.
 404
 405 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 406
 407         * boot-9.scm (resolve-module): New optional parameter that
 408         controls whether autoloading is attempted or not. Default is #t.
 409         (process-define-module): Don't autoload the defined module.
 410         (try-module-autoload): Don't autoload the directory modules.
 411
 412         * boot-9.scm (process-define-module): Ensure that the-scm-module
 413         is last in the `uses' list to allow shadowing builtin
 414         bindings. All :use-module options are added in the order they
 415         appear in the arguments but before anything already on the list
 416         (such as the-scm-module).
 417
 418 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 419
 420         * slib.scm (slib-parent-dir): throw error if #f returned from
 421         %search-load-path.
 422
 423 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 424
 425         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 426         * Makefile.am, aclocal.m4: New files.
 427         * configure.in: Updated for Automake.
 428
 429 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 430
 431         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 432         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 433         function, use it accordingly.
 434
 435 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 436
 437         It's an "eval closure", not an "eval thunk."  A thunk is a
 438         function of no arguments.
 439         * boot-9.scm (module-type): Rename module field.
 440         (make-module, eval-in-module, make-root-module,
 441         set-current-module): Uses changed.
 442         (module-eval-closure, set-module-eval-closure!,
 443         root-module-closure): Renamed from module-eval-thunk,
 444         set-module-eval-thunk!, root-module-thunk.
 445         (set-current-module): Change uses of *top-level-lookup-thunk* to
 446         *top-level-eval-closure*.
 447
 448 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 449
 450         * slib.scm (slib-parent-dir): Use string-length, not length.
 451         (Thanks to Bernard Urban.)
 452
 453 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 454
 455         * boot-9.scm: The debugging evaluator and recording of positions
 456         aren't enabled by default any longer (they are switched on in
 457         debug.scm).  But during development we want to have them also
 458         *inside* boot-9.scm.  Therefore, two lines are added at the
 459         beginning of boot-9.scm to enable these.
 460
 461         Call `provide' so that `records' are included among the
 462         `*features*'.
 463
 464         The scheme for saving the stack has been adjusted: save-stack is
 465         now commonly available for saving the stack.  Calling `save-stack'
 466         sets a flag `stack-saved?' which prevents overwriting the stack.
 467         `stack-saved?' is reset at `abort'.
 468
 469         Spelling correction: seperate --> separate.
 470
 471         Removed `:'s that had creeped into some comments.
 472
 473         The repl now doesn't print #<unspecified> results any longer
 474         If the user wants to see this, he can do
 475         (assert-repl-print-unspecified #t) in his startup file.
 476
 477         The user now gets a friendly message instead of a backtrace at
 478         error.
 479
 480         Added `before-read-hook'.
 481
 482         Load module (ice-9 emacs) if option `-e' was specified.
 483
 484         (provide): New function.
 485
 486         (error): Save stack at entry, so that Guile entrails won't show up
 487         in backtraces.
 488
 489         (backtrace): New function.
 490
 491         (save-stack): Can now take arbitrary number of stack narrowing
 492         specifier pairs.  The first specifier in a pair controls inner
 493         border, the second the outer border.  A number means cut that
 494         number of frames, a procedure object means cut until that object
 495         is found in operator position in a frame.
 496
 497         * debug.scm: Enable debugging evaluator and recording of positions
 498         by default.
 499
 500         * slib.scm (slib:load): Adapt to the new behavior of
 501         primitive-load: It doesn't any longer try both with and without
 502         ".scm" extension.  (We don't want to use %search-load-path here.)
 503
 504         (implementation-vicinity): New function.  slib requires it
 505
 506         (library-vicinity): Updated.
 507
 508         Load "require.scm" in the library-vicinity.
 509
 510         (install-require-vicinity, install-require-module): New functions.
 511
 512 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 513
 514         * boot-9.scm (load-from-path): New function.
 515
 516         * boot-9.scm (try-load, basic-try-load, try-load-module,
 517         try-load): Deleted.  I don't think they're being used.
 518
 519         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 520         so they'll get distributed.
 521
 522         Get Guile to be a little less chatty by default.  The new user
 523         should see as little clutter as possible.
 524         * r4rs.scm (%load-verbosely): Make this #f by default.
 525         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 526         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 527
 528         * r4rs.scm: New file.
 529         * boot-9.scm: Load r4rs.scm, first thing.
 530         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 531         open-output-file, open-io-file, close-input-port,
 532         close-output-port, close-io-port, call-with-input-file,
 533         call-with-output-file, with-input-from-port, with-output-to-port,
 534         with-error-to-port, with-input-from-file, with-output-to-file,
 535         with-error-to-file, with-input-from-string, with-output-to-string,
 536         with-error-to-string, the-eof-object): Definitions moved to
 537         r4rs.scm.  Not all of them are R4RS, but those that are use those
 538         that are not.
 539         (load, %load-verbosely, %load-announce): Moved, along with code to
 540         set %load-hook, to r4rs.scm.
 541
 542         * test.scm: New file.
 543
 544         * boot-9.scm (integer?): Definition deleted, in favor of the one
 545         present in libguile (which used to be called int?).  I have no
 546         idea why integer? didn't just call int? to begin with.
 547
 548         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 549         =?, >?, and >=? deleted; they're defined that way by libguile now.
 550
 551         * boot-9.scm (load): Simplified; primitive-load does most of this
 552         work now.
 553         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 554         call %load-announce.
 555
 556 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 557
 558         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 559         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 560         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 561         components.
 562         (file-is-directory?): use stat:type.
 563
 564 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 565
 566         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 567         that's now taken care of in libguile, and in a way compatible with
 568         SCSH (which this isn't).
 569
 570 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 571
 572         * boot-9.scm: Formatting tweaks.
 573
 574 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 575
 576         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 577         after-error-hook, before-backtrace-hook and after-backtrace-hook
 578         to the error handler.  E.g.: fancy emacs support could plug into
 579         these.
 580         (save-stack): New function.  The stack is now made differently
 581         depending on the stack id.  (The motivation is to make a better
 582         choice regarding what stack frames to present to the user.)
 583         (error-catching-loop): Stack handling code moved outside into
 584         save-stack.
 585
 586 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 587
 588         * Makefile.in (scm_files): add expect.scm.
 589
 590         * expect.scm: new file ported from guile-iii.
 591
 592         * boot-9.scm: remove handle-system-error, after moving the code into
 593         error-catching-loop.
 594         Don't set 'throw-handler-default property on error keys.
 595         Just interpret (almost) any throw with 4 args as an error throw.
 596         Delete some try-load stuff that was already commented out.
 597
 598         Second thoughts, keep handle-system-error but call it from
 599         error-catching-loop.
 600
 601 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 602
 603         * boot-9.scm: Doc fixes.
 604         (make-module): Rework for readability.
 605         (make-root-module, make-scm-module): USES argument to make-module
 606         should be '(), not #f.
 607
 608         * boot-9.scm (try-load): %sys-load-path has been renamed to
 609         primitive-load-path; adjust call here.
 610
 611 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 612
 613         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 614         the stack to the correct place: when it is decided to generate an
 615         error-signal.
 616
 617 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 618
 619         * boot-9.scm (error-catching-loop, signal-handler,
 620         handle-system-error): Backtracing now works for signals aswell;
 621         Backtracing mechanism can now identify the stack root created by
 622         start-stack so that the user isn't exposed to system stack frames.
 623
 624 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 625
 626         * Makefile.in: Added threads.scm.
 627
 628 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 629
 630         * debug.scm (make-enable, make-disable): Simplified.
 631
 632         * boot-9.scm: Renamed %%throw-handler-default -->
 633         throw-handler-default.
 634         ((handle-system-error key . arg-list)): Changed the way errors are
 635         reported.
 636         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 637         acro.
 638         ((error-catching-loop thunk)): Introduce a lazy-catch into
 639         error-catching-loop so that the stack can be captured.
 640
 641 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 642
 643         * mapping.scm (hash-table-mapping): Explicitly request that
 644         make-vector fill new vectors with '(); this will make it easier to
 645         port Guile Scheme code to other Schemes.
 646         * boot-9.scm (make-print-style, make-print-table): Same.
 647
 648 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 649
 650         * boot-9.scm (load): rewritten again.
 651         Append "." to the default %load-path.
 652         (feature?): new function: checks for a symbol in the features list.
 653         (module-local-variable): remove apparently useless (caddr (list m v
 654         ...))
 655         (%load-announce): minor formatting change.
 656         (file-exists?): use access? if posix is featured.
 657         (file-is-directory?): use stat if i/o-extensions is featured.
 658         (try-module-autoload module-name): use file-exists? before
 659         file-is-directory?
 660
 661 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 662
 663         * boot-9.scm: Added conditional loading of threads.scm.
 664
 665         * threads.scm: New file.  Modified from the Cygnus-r0.3
 666         distribution.
 667
 668         * boot-9.scm (error-catching-loop): Added handling of key
 669         `switch-repl'.
 670
 671         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 672
 673 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 674
 675         * boot-9.scm (make-record-type, record-constructor): Don't assume
 676         the empty list is false when parsing the argument list.
 677
 678 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 679
 680         * boot-9.scm (signal-handler): Clean up logic.
 681
 682         * boot-9.scm (load): Assume %load-path is always bound.
 683
 684 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 685
 686         * boot-9.scm (error): replace another throw with scm-error.  Throw
 687         to 'misc-error instead of 'error (no need to distinguish these.)
 688         Don't set up 'error as a key.
 689         Set up regex-error as a key, if regex is available.
 690         (signal-handler): use scm-error, not throw.
 691
 692         (%try-load, try-load-with-path, %load, load-with-path,
 693         basic-try-load-with-path, basic-load-with-path,
 694         try-load-module-with-path,load-module-with-path): deleted, since
 695         they seem redundant.
 696         (try-load): define using %try-load, not try-load-with-path.
 697         (load): rewritten.  load tries to open the file directly and
 698         with a .scm extension before searching the library directories
 699         (should "." be added to %load-path?  then load could still open
 700         directly files starting with "/").
 701         (try-module-autoload): use load, not load-with-path.
 702         (%load-indent): deleted, -2 was causing errors.
 703
 704         (%read-sharp): use port-line, not line-number.
 705
 706 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 707
 708         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 709         straightforward to provide the equivalent functionality using
 710         (catch #t ...), so there's no need for the extra complexity.  2)
 711         Outside the context of a read-eval-print loop (which Guile should
 712         not require) it's not clear we should do anything more complicated
 713         than print an error and exit; the user or REPL can establish
 714         something better if it wants.  3) In that case, it's much more
 715         robust to just do it in the C code.
