ice-9/ChangeLog

   1 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
   2
   3         * boot-9.scm (define-public): Changed to accomodate Hobbit.
   4
   5 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
   6
   7         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
   8         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
   9         notation, instead of #/ notation.
  10
  11         * expect.scm (expect-strings): Pass regexp/newline flag to
  12         make-regexp.
  13
  14 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
  15
  16         Fix inconsistencies in parsing of #/ style lists.
  17         * boot-9.scm (read-path-list-notation): New function.
  18         (parse-path-symbol): Deleted.  Replaced by above.
  19         Plug in read-path-list-notation as the parser for #/ lists,
  20         instead of the anonymous lambda form calling parse-path-symbol.
  21         (Thanks to Maurizio Vitale.)
  22
  23         * boot-9.scm (make-list): Remove the definition of this function
  24         from the (ice-9 common-list) module; make the `init' argument
  25         optional in the scm module's definition, to match the deleted
  26         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
  27
  28 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
  29
  30         Try to detect when people are using one version of libguile and a
  31         different version of ice-9.  People have been skewing things and
  32         sending in bug reports.
  33         * version.scm.in: New file, which the configure script munges to
  34         produce version.scm, which contains the ice-9 config stamp.
  35         * boot-9.scm: Compare the libguile and ice-9 config stamps;
  36         display a warning if the two are different.
  37         * Makefile.am: Install version.scm, but don't distribute it.
  38         Distribute version.scm.in, but don't install it.
  39         * Makefile.in: Regenerated.
  40
  41 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
  42
  43         * slib.scm (slib:warn): Alias for WARN function.
  44
  45 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
  46
  47         * boot-9.scm (struct-printer): Fix off-by-one error in range
  48         check.  Correctly check for struct printer tag.
  49
  50         * expect.scm: Turn this into a module, (ice-9 expect).
  51         (expect-port, expect-timeout, expect-timeout-proc,
  52         expect-eof-proc, expect-char-proc, expect, expect-strings,
  53         expect-select): Make these public definitions.
  54         (expect-strings): Use make-regexp and regexp-exec, instead of
  55         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
  56         that's okay.
  57
  58         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
  59         users in the core, and relies on mildly hairy details of the old
  60         regexp interface.
  61
  62         * test.scm: Re-enable tests asserting that '() is true, and not a
  63         boolean.  This stuff has been true for a while.
  64
  65         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
  66         function names.
  67
  68         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
  69         fixes.
  70
  71 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
  72
  73         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
  74         ../configure.in.
  75
  76 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  77
  78         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
  79         vtable and not the one of the struct.
  80
  81 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  82
  83         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
  84         make-struct-printer, set-struct-printer-in-vtable!): New bindings
  85         to support printing of structures.
  86         (record-type-vtable, make-record-type): Add slot to hold printing
  87         function and initialize it with something appropriate.  Removed
  88         commented out printing code.
  89         (record-type-name, record-type-fields): Adjusted slot offsets.
  90         (%print-module): Reduce argument list to "mod" and "port".
  91
  92 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  93
  94         * slib.scm (identity): New function, used by SLIB.
  95
  96 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
  97
  98         * boot-9.scm: signal-handler, alarm-thunk: removed.
  99         don't define ticks-interrupt etc.
 100         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
 101         during call to scm-style-repl.
 102
 103 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
 104
 105         * slib.scm (slib:load): Use primitive-load-path instead of
 106         basic-load.  This is probably wrong, but hopefully the entire
 107         source access system will be revised soon anyway, and this will
 108         make require behave more like Emacs Lisp's require.  If this
 109         breaks something, please let me know.  Maybe this is real dumb.
 110
 111 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
 112
 113         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
 114         * boot-9.scm: If the `regex' feature is present, use the module
 115         (ice-9 regex).
 116
 117 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
 118
 119         * regex.scm: New file.
 120         * Makefile.am (subpkgdata_DATA): Add regex.scm.
 121         * Makefile.in: Regenerated.
 122
 123 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
 124
 125         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
 126         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
 127         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
 128         threads.scm: New address for FSF.
 129
 130 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
 131
 132         * debug.scm: Update copyright years; this file has been worked on
 133         in 1997.
 134
 135 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
 136
 137         * expect.scm: use gettimeofday instead of get-internal-real-time
 138         and use a floating point timeout when calling select.  Untested,
 139         since the regex library is currently AWOL.
 140
 141 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
 142
 143         * boot-9.scm (eval-string): Function deleted; it was already
 144         implemented in C, so there's no point in making a divergable copy
 145         here.
 146
 147 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 148
 149         * Makefile.in: Regenerated, using automake-1.1p.
 150
 151 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 152
 153         * Makefile.in: Regenerated, using automake-1.1p.
 154
 155 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 156
 157         * boot-9.scm (error-catching-loop): don't read a line from
 158         current input when quit is encountered, the previous change
 159         fixes this too.
 160
 161 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
 162
 163         * boot-9.scm (scm-style-repl): After reading an expression,
 164         consume any trailing newline (perhaps preceded by whitespace), to
 165         avoid screwing up GDB.  More detail in comments.
 166
 167 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
 168
 169         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
 170         the Scheme code like code yet.
 171         * Makefile.in: Resrac,husrched.
 172
 173 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 174
 175         * boot-9.scm (link-dynamic-module): Do not catch errors from
 176         dynamic-link and dynamic-call.  When the shared library exists it
 177         is now assumed to be suitable for a dynamic C module.
 178
 179 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 180
 181         * boot-9.scm (process-use-modules): New function to support the
 182         use-modules macro
 183         (use-modules): throw an error iff one of the requested modules
 184         can't be found.
 185
 186 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 187
 188         * boot-9.scm: don't define timer-thunk or gc-thunk.
 189
 190 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 191
 192         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 193
 194         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 195         we're not using AM_INIT_GUILE_MODULE any more.
 196         * Makefile.in: Regeneratitetedrerd.
 197
 198 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 199
 200         Get 'make dist' to work again.
 201         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 202         * Makefile.in: Regenerated, like two tons of fleas.
 203
 204         Changes for reduced Guile distribution: one configure script,
 205         no plugins.
 206         * configure.in, configure: Removed.
 207         * Makefile.in: Regenerated.
 208

 210
 211         * boot-9.scm (eval-string, command-line, load-user-init): New
 212         functions.
 213
 214 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 215
 216         * boot-9.scm (log10): defined.
 217
 218 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 219
 220         * expect.scm (expect-select): correct the millisecond timeout
 221         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 222
 223 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 224
 225         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 226         instead of in libguile.
 227         (tm:sec etc.) new accessors for broken-down time.
 228         (set-tm:sec etc.) new setters for broken-down time.
 229
 230 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 231
 232         * boot-9.scm (netent:addrtype, servent:port): added missing
 233         procedures.
 234         (netent:net, servent:proto): repaired.
 235         (utsname:sysname etc.): new accessors for uname.
 236
 237 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 238
 239         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 240         sockaddr:port): new functions.
 241
 242 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 243
 244         * boot-9.scm: define accessor procedures for the objects returned
 245         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 246         passwd:name, where the first component is the name of the C structure
 247         and the second is the unprefixed C member name.)
 248
 249 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 250
 251         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 252         setservent): no longer take an argument, it was bogus.
 253
 254 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 255
 256         * boot-9.scm (scm-error): deleted, reimplemented in C.
 257
 258 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 259
 260         * boot-9.scm (process-define-module): Modified to handle both
 261         keywords and symbols.
 262
 263 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 264
 265         * slib.scm: update read usage.
 266
 267         * r4rs.scm: update primitive-load usage.
 268         Don't define read-sharp.
 269
 270         * boot-9.scm: use read-hash-extend to install extra read syntax.
 271         (read-sharp): removed.
 272         Adjust usage of primitive-load-path, read, which no longer take
 273         case_i or read-sharp arguments.
 274
 275 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 276
 277         * boot-9.scm: Added loading of session support module.
 278
 279         * debug.scm: Removed `display-application'.  (Replaced by
 280         primitive procedure.)
 281
 282         * boot-9.scm (beautify-user-module!): Don't add the root module
 283         interface to the end of the use-list of the root module.
 284

 286
 287         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 288
 289 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 290
 291         * boot-9.scm: check use-emacs-interface for emacs support.
 292
 293 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 294
 295         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 296         read gets EOF.
 297         * (exit): alias for quit.
 298
 299 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 300
 301         * boot-9.scm (error-catching-loop thunk): use a status variable to
 302         return the quit args.
 303         (scm-style-repl): call -quit, passing return value from
 304         error-catching-repl.  Make -quit return its args.
 305         stand-alone-repl: comment out, since it seems unused.
 306
 307         (error-catching-loop thunk): discard trailing junk after a (quit).
 308
 309 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 310
 311         * boot-9.scm: Removed the old printer code.
 312
 313         * r4rs.scm (apply, call-with-current-continuation): Added comment
 314         explaining why apply and call/cc need to be closures.
 315
 316         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 317         Removed. These definitions are already present in r4rs.scm.
 318
 319         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 320         stack before printing traced frames; Re-enable trace flag at end
 321         of handlers.
 322
 323 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 324
 325         * debug.scm: Add hook for reset of trace level at abort.
 326
 327         * boot-9.scm (run-hooks): New procedure.
 328         (add-hooks!): New macro.
 329         Change hooks to use these functions.
 330
 331         * debug.scm: *Warning* This feature is a bit premature.  I add
 332         it anyway because 1. it is very useful, and, 2. you can start
 333         making it less premature by complaining to me and by modifying
 334         the source! :-)
 335         (trace): Given one or more procedure objects, trace each one.
 336         Given no arguments, show all traced procedures.
 337         (untrace): Given one or more procedure objects, untrace each one.
 338         Given no arguments, untrace all traced procedures.  The tracing in
 339         Guile have an advantage to most other systems: We don't create new
 340         procedure objects, but mark the procedure objects themselves.
 341         This means that also anonymous and internal procedures can be
 342         traced.
 343
 344         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 345         and exit-frame exceptions.
 346
 347         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 348         (set-repl-prompt!): Setter for repl prompt.
 349         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 350         string, display it; if prompt is a thunk, call it and display its
 351         result; otherwise display "> ".
 352         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 353
 354         * r4rs.scm (%load-verbosely): Reverted change to
 355         `module-defined?', since the module system isn't bootstrapped when
 356         we load r4rs.scm.  This is just a temporary fix to make the
 357         repository version runnable.
 358
 359 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 360
 361         * boot-9.scm: Removed the enabling of debug evaluator and
 362         recording of source code positions.  This was placed there for our
 363         convenience, but it has already sneaked into the distribution
 364         once... so we'd better add this in our local copies instead when
 365         we need it.  (These options are normally enabled at the end of
 366         boot-9.scm when loading the debug module.)

 368 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 369
 370         * boot-9.scm (module-defined?): New function.
 371         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 372         and eval.
 373         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 374         "defined?".
 375         * slib.scm (defined?): New function to take the place of the
 376         builtin "defined?".  It allways examines the slib module.
 377
 378 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 379
 380         * configure.in: Added AM_MAINTAINER_MODE
 381
 382 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 383
 384         * boot-9.scm (read-sharp): define directly, don't go through a
 385         %read-sharp layer.
 386
 387 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 388
 389         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 390         uniform-vector-set1! which doesn't exist.
 391
 392 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 393
 394         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 395         backtrace.c.)
 396
 397 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 398
 399         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 400         read-line): new procedures, see libguile/ChangeLog.
 401
 402 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 403
 404         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 405
 406         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 407         init-dynamic-module, dynamic-maybe-call,
 408         find-and-link-dynamic-module, link-dynamic-module,
 409         try-module-dynamic-link, registered-modules): New definitions for
 410         dynamic linking of modules.
 411         (resolve-module): Try to dynamically link the requested module
 412         after failing to load it as Scheme code.
 413
 414 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 415
 416         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 417
 418 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 419
 420         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 421         that's what it is.
 422
 423         * lineio.scm (make-line-buffering-input-port): Properly test for
 424         the case of an empty buffer list.  The old code assumed that '()
 425         was false.
 426
 427 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 428
 429         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 430         (use-modules <module name> ...) Put the the modules named by
 431         <module name> ... on the use list of the current module.
 432
 433 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 434
 435         * boot-9.scm (error-catching-loop): Remove message saying that
 436         typing "$" will put you in the debugger.  This isn't implemented
 437         yet.
 438
 439 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 440
 441         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 442         been fixed, so this function is superfluous.
 443         (transform-usage-lambda): Use delq!, not delq-all!.
 444
 445 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 446
 447         * boot-9.scm (resolve-module): New optional parameter that
 448         controls whether autoloading is attempted or not. Default is #t.
 449         (process-define-module): Don't autoload the defined module.
 450         (try-module-autoload): Don't autoload the directory modules.
 451
 452         * boot-9.scm (process-define-module): Ensure that the-scm-module
 453         is last in the `uses' list to allow shadowing builtin
 454         bindings. All :use-module options are added in the order they
 455         appear in the arguments but before anything already on the list
 456         (such as the-scm-module).
 457
 458 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 459
 460         * slib.scm (slib-parent-dir): throw error if #f returned from
 461         %search-load-path.
 462
 463 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 464
 465         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 466         * Makefile.am, aclocal.m4: New files.
 467         * configure.in: Updated for Automake.
 468
 469 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 470
 471         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 472         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 473         function, use it accordingly.
 474
 475 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 476
 477         It's an "eval closure", not an "eval thunk."  A thunk is a
 478         function of no arguments.
 479         * boot-9.scm (module-type): Rename module field.
 480         (make-module, eval-in-module, make-root-module,
 481         set-current-module): Uses changed.
 482         (module-eval-closure, set-module-eval-closure!,
 483         root-module-closure): Renamed from module-eval-thunk,
 484         set-module-eval-thunk!, root-module-thunk.
 485         (set-current-module): Change uses of *top-level-lookup-thunk* to
 486         *top-level-eval-closure*.
 487
 488 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 489
 490         * slib.scm (slib-parent-dir): Use string-length, not length.
 491         (Thanks to Bernard Urban.)
 492
 493 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 494
 495         * boot-9.scm: The debugging evaluator and recording of positions
 496         aren't enabled by default any longer (they are switched on in
 497         debug.scm).  But during development we want to have them also
 498         *inside* boot-9.scm.  Therefore, two lines are added at the
 499         beginning of boot-9.scm to enable these.
 500
 501         Call `provide' so that `records' are included among the
 502         `*features*'.
 503
 504         The scheme for saving the stack has been adjusted: save-stack is
 505         now commonly available for saving the stack.  Calling `save-stack'
 506         sets a flag `stack-saved?' which prevents overwriting the stack.
 507         `stack-saved?' is reset at `abort'.
 508
 509         Spelling correction: seperate --> separate.
 510
 511         Removed `:'s that had creeped into some comments.
 512
 513         The repl now doesn't print #<unspecified> results any longer
 514         If the user wants to see this, he can do
 515         (assert-repl-print-unspecified #t) in his startup file.
 516
 517         The user now gets a friendly message instead of a backtrace at
 518         error.
 519
 520         Added `before-read-hook'.
 521
 522         Load module (ice-9 emacs) if option `-e' was specified.
 523
 524         (provide): New function.
 525
 526         (error): Save stack at entry, so that Guile entrails won't show up
 527         in backtraces.
 528
 529         (backtrace): New function.
 530
 531         (save-stack): Can now take arbitrary number of stack narrowing
 532         specifier pairs.  The first specifier in a pair controls inner
 533         border, the second the outer border.  A number means cut that
 534         number of frames, a procedure object means cut until that object
 535         is found in operator position in a frame.
 536
 537         * debug.scm: Enable debugging evaluator and recording of positions
 538         by default.
 539
 540         * slib.scm (slib:load): Adapt to the new behavior of
 541         primitive-load: It doesn't any longer try both with and without
 542         ".scm" extension.  (We don't want to use %search-load-path here.)
 543
 544         (implementation-vicinity): New function.  slib requires it
 545
 546         (library-vicinity): Updated.
 547
 548         Load "require.scm" in the library-vicinity.
 549
 550         (install-require-vicinity, install-require-module): New functions.
 551
 552 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 553
 554         * boot-9.scm (load-from-path): New function.
 555
 556         * boot-9.scm (try-load, basic-try-load, try-load-module,
 557         try-load): Deleted.  I don't think they're being used.
 558
 559         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 560         so they'll get distributed.
 561
 562         Get Guile to be a little less chatty by default.  The new user
 563         should see as little clutter as possible.
 564         * r4rs.scm (%load-verbosely): Make this #f by default.
 565         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 566         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 567
 568         * r4rs.scm: New file.
 569         * boot-9.scm: Load r4rs.scm, first thing.
 570         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 571         open-output-file, open-io-file, close-input-port,
 572         close-output-port, close-io-port, call-with-input-file,
 573         call-with-output-file, with-input-from-port, with-output-to-port,
 574         with-error-to-port, with-input-from-file, with-output-to-file,
 575         with-error-to-file, with-input-from-string, with-output-to-string,
 576         with-error-to-string, the-eof-object): Definitions moved to
 577         r4rs.scm.  Not all of them are R4RS, but those that are use those
 578         that are not.
 579         (load, %load-verbosely, %load-announce): Moved, along with code to
 580         set %load-hook, to r4rs.scm.
 581
 582         * test.scm: New file.
 583
 584         * boot-9.scm (integer?): Definition deleted, in favor of the one
 585         present in libguile (which used to be called int?).  I have no
 586         idea why integer? didn't just call int? to begin with.
 587
 588         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 589         =?, >?, and >=? deleted; they're defined that way by libguile now.
 590
 591         * boot-9.scm (load): Simplified; primitive-load does most of this
 592         work now.
 593         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 594         call %load-announce.
 595
 596 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 597
 598         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 599         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 600         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 601         components.
 602         (file-is-directory?): use stat:type.
 603
 604 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 605
 606         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 607         that's now taken care of in libguile, and in a way compatible with
 608         SCSH (which this isn't).
 609
 610 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 611
 612         * boot-9.scm: Formatting tweaks.
 613
 614 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 615
 616         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 617         after-error-hook, before-backtrace-hook and after-backtrace-hook
 618         to the error handler.  E.g.: fancy emacs support could plug into
 619         these.
 620         (save-stack): New function.  The stack is now made differently
 621         depending on the stack id.  (The motivation is to make a better
 622         choice regarding what stack frames to present to the user.)
 623         (error-catching-loop): Stack handling code moved outside into
 624         save-stack.
 625
 626 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 627
 628         * Makefile.in (scm_files): add expect.scm.
 629
 630         * expect.scm: new file ported from guile-iii.
 631
 632         * boot-9.scm: remove handle-system-error, after moving the code into
 633         error-catching-loop.
 634         Don't set 'throw-handler-default property on error keys.
 635         Just interpret (almost) any throw with 4 args as an error throw.
 636         Delete some try-load stuff that was already commented out.
 637
 638         Second thoughts, keep handle-system-error but call it from
 639         error-catching-loop.
 640
 641 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 642
 643         * boot-9.scm: Doc fixes.
 644         (make-module): Rework for readability.
 645         (make-root-module, make-scm-module): USES argument to make-module
 646         should be '(), not #f.
 647
 648         * boot-9.scm (try-load): %sys-load-path has been renamed to
 649         primitive-load-path; adjust call here.
 650
 651 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 652
 653         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 654         the stack to the correct place: when it is decided to generate an
 655         error-signal.
 656
 657 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 658
 659         * boot-9.scm (error-catching-loop, signal-handler,
 660         handle-system-error): Backtracing now works for signals aswell;
 661         Backtracing mechanism can now identify the stack root created by
 662         start-stack so that the user isn't exposed to system stack frames.
 663
 664 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 665
 666         * Makefile.in: Added threads.scm.
 667
 668 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 669
 670         * debug.scm (make-enable, make-disable): Simplified.
 671
 672         * boot-9.scm: Renamed %%throw-handler-default -->
 673         throw-handler-default.
 674         ((handle-system-error key . arg-list)): Changed the way errors are
 675         reported.
 676         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 677         acro.
 678         ((error-catching-loop thunk)): Introduce a lazy-catch into
 679         error-catching-loop so that the stack can be captured.
 680
 681 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 682
 683         * mapping.scm (hash-table-mapping): Explicitly request that
 684         make-vector fill new vectors with '(); this will make it easier to
 685         port Guile Scheme code to other Schemes.
 686         * boot-9.scm (make-print-style, make-print-table): Same.
 687
 688 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 689
 690         * boot-9.scm (load): rewritten again.
 691         Append "." to the default %load-path.
 692         (feature?): new function: checks for a symbol in the features list.
 693         (module-local-variable): remove apparently useless (caddr (list m v
 694         ...))
 695         (%load-announce): minor formatting change.
 696         (file-exists?): use access? if posix is featured.
 697         (file-is-directory?): use stat if i/o-extensions is featured.
 698         (try-module-autoload module-name): use file-exists? before
 699         file-is-directory?
 700
 701 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 702
 703         * boot-9.scm: Added conditional loading of threads.scm.
 704
 705         * threads.scm: New file.  Modified from the Cygnus-r0.3
 706         distribution.
 707
 708         * boot-9.scm (error-catching-loop): Added handling of key
 709         `switch-repl'.
 710
 711         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 712
 713 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 714
 715         * boot-9.scm (make-record-type, record-constructor): Don't assume
 716         the empty list is false when parsing the argument list.
 717
 718 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 719
 720         * boot-9.scm (signal-handler): Clean up logic.
 721
 722         * boot-9.scm (load): Assume %load-path is always bound.
 723
 724 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 725
 726         * boot-9.scm (error): replace another throw with scm-error.  Throw
 727         to 'misc-error instead of 'error (no need to distinguish these.)
 728         Don't set up 'error as a key.
 729         Set up regex-error as a key, if regex is available.
 730         (signal-handler): use scm-error, not throw.
 731
 732         (%try-load, try-load-with-path, %load, load-with-path,
 733         basic-try-load-with-path, basic-load-with-path,
 734         try-load-module-with-path,load-module-with-path): deleted, since
 735         they seem redundant.
 736         (try-load): define using %try-load, not try-load-with-path.
 737         (load): rewritten.  load tries to open the file directly and
 738         with a .scm extension before searching the library directories
 739         (should "." be added to %load-path?  then load could still open
 740         directly files starting with "/").
 741         (try-module-autoload): use load, not load-with-path.
 742         (%load-indent): deleted, -2 was causing errors.
 743
 744         (%read-sharp): use port-line, not line-number.
 745
 746 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 747
 748         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 749         straightforward to provide the equivalent functionality using
 750         (catch #t ...), so there's no need for the extra complexity.  2)
 751         Outside the context of a read-eval-print loop (which Guile should
 752         not require) it's not clear we should do anything more complicated
 753         than print an error and exit; the user or REPL can establish
 754         something better if it wants.  3) In that case, it's much more
 755         robust to just do it in the C code.
 756
 757 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 758
 759         * boot-9.scm (%try-load): define using primitive-load.  Previously
 760         %try-load itself was the primitive.
 761         (load-with-path): use scm-error instead of %load-announce-lossage.
 762         Errors are thrown to 'misc-error instead of 'could-not-load.
 763         (%load-announce-lossage): deleted.
 764
 765 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 766
 767         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 768         (make-record-type type-name fields): Temporarily remove support
 769         for printing of records (not possible yet with C printer).
 770
 771 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 772
 773         * boot-9.scm (file-exists?, file-is-directory): catch only
 774         system-error, not every kind of error.
 775         (scm-error): new procedure.
 776
 777 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>

 781 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 782
 783         * boot-9.scm (%%handle-system-error key): remove the code for
 784         SCM-style errors.  handle the case that an unexpected number
 785         of args are supplied.
 786         (%%system-errors): removed.
 787         (error): redefine using a throw with key and 4 args.
 788         ('error): associate 'error, 'error-signal keys with
 789         %%handle-system-error.
 790         (%%default-error-handler): removed.
 791         (signal-handler): throw with 4 args and use the error-signal key.
 792         Create an error message instead of using numerical codes.
 793         (%%bad-throw): call error instead of throw if key not found.
 794
 795 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 796
 797         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 798         (%%handle-system-error key): check subr is not #f before printing.
 799         Recognize %s (embed an argument using "display") and
 800         %S (embed an argument using "write").
 801
 802 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 803
 804         * boot-9.scm (%%handle-system-error key): set args and rest to
 805         the empty list if they are #f.
 806         Initialize out-of-range as an error key.
 807
 808 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 809
 810         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 811
 812         * boot-9.scm: remove leading %% from references to '%%system-error.
 813         (%%handle-system-error): don't pass all the thrown arguments when
 814         aborting, just the key and subr.
 815         Remove the code to "Install default handlers for built-in errors."
 816         Remove the definition of the syserror procedure.
 817         Associate 'numerical-overflow with default handler.
 818
 819 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 820
 821         * boot-9.scm: Name change: value-ref --> local-ref
 822         resolved-ref --> nested-ref  Motivation: conformance to the other
 823         dictionary operators: list-ref operates on list, vector-ref
 824         operates on vector, nested-ref operates on nested namespace,
 825         local-ref operates on the local nested namespace.

 827 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 828
 829         * boot-9.scm (%%handle-system-error): recognise errors thrown
 830         by lgh-error (fill-message etc.)
 831         (fill-message): check first whether args is null.
 832         (fill-message): bug fix and check that args is a list.

 838         initialize %load-path.
 839
 840         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 841         "/", use one to separate it from the file.
 842
 843 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 844
 845         * boot-9.scm (%load-path): Add the site directory.
 846         Add the directory named after the version number.
 847         Prepend the version number to the other directories in the path.
 848         Simplify by mapping the common prefix onto each item.
 849         * Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
 850         sitedatadir): New definitions.

 857
 858         Don't use the PLUGIN system to gather information for the
 859         Makefile's distribution and installation targets; just put it all
 860         in the Makefile directly.
 861         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 862         for these.
 863         * configure.in: Remove code that gets and substitutes scm_files and
 864         aux_files.
 865         * Makefile.in (scm_files, aux_files): Write out the list of files
 866         here, where people expect to find them.

 901         (manifest): Deleted.
 902         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
