   1 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
   2
   3         Changes to compile under gnu-win32, from Marcus Daniels:
   4         * boot-9.scm (load-user-init): If HOME is unset, provide
   5         a default of /.
   6
   7         * boot-9.scm (define-public): Changed to accomodate Hobbit.
   8
   9 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
  10
  11         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
  12         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
  13         notation, instead of #/ notation.
  14
  15         * expect.scm (expect-strings): Pass regexp/newline flag to
  16         make-regexp.
  17
  18 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
  19
  20         Fix inconsistencies in parsing of #/ style lists.
  21         * boot-9.scm (read-path-list-notation): New function.
  22         (parse-path-symbol): Deleted.  Replaced by above.
  23         Plug in read-path-list-notation as the parser for #/ lists,
  24         instead of the anonymous lambda form calling parse-path-symbol.
  25         (Thanks to Maurizio Vitale.)
  26
  27         * boot-9.scm (make-list): Remove the definition of this function
  28         from the (ice-9 common-list) module; make the `init' argument
  29         optional in the scm module's definition, to match the deleted
  30         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
  31
  32 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
  33
  34         Try to detect when people are using one version of libguile and a
  35         different version of ice-9.  People have been skewing things and
  36         sending in bug reports.
  37         * version.scm.in: New file, which the configure script munges to
  38         produce version.scm, which contains the ice-9 config stamp.
  39         * boot-9.scm: Compare the libguile and ice-9 config stamps;
  40         display a warning if the two are different.
  41         * Makefile.am: Install version.scm, but don't distribute it.
  42         Distribute version.scm.in, but don't install it.
  43         * Makefile.in: Regenerated.
  44
  45 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
  46
  47         * slib.scm (slib:warn): Alias for WARN function.
  48
  49 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
  50
  51         * boot-9.scm (struct-printer): Fix off-by-one error in range
  52         check.  Correctly check for struct printer tag.
  53
  54         * expect.scm: Turn this into a module, (ice-9 expect).
  55         (expect-port, expect-timeout, expect-timeout-proc,
  56         expect-eof-proc, expect-char-proc, expect, expect-strings,
  57         expect-select): Make these public definitions.
  58         (expect-strings): Use make-regexp and regexp-exec, instead of
  59         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
  60         that's okay.
  61
  62         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
  63         users in the core, and relies on mildly hairy details of the old
  64         regexp interface.
  65
  66         * test.scm: Re-enable tests asserting that '() is true, and not a
  67         boolean.  This stuff has been true for a while.
  68
  69         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
  70         function names.
  71
  72         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
  73         fixes.
  74
  75 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
  76
  77         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
  78         ../configure.in.
  79
  80 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  81
  82         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
  83         vtable and not the one of the struct.
  84
  85 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  86
  87         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
  88         make-struct-printer, set-struct-printer-in-vtable!): New bindings
  89         to support printing of structures.
  90         (record-type-vtable, make-record-type): Add slot to hold printing
  91         function and initialize it with something appropriate.  Removed
  92         commented out printing code.
  93         (record-type-name, record-type-fields): Adjusted slot offsets.
  94         (%print-module): Reduce argument list to "mod" and "port".
  95
  96 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
  97
  98         * slib.scm (identity): New function, used by SLIB.
  99
 100 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
 101
 102         * boot-9.scm: signal-handler, alarm-thunk: removed.
 103         don't define ticks-interrupt etc.
 104         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
 105         during call to scm-style-repl.
 106
 107 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
 108
 109         * slib.scm (slib:load): Use primitive-load-path instead of
 110         basic-load.  This is probably wrong, but hopefully the entire
 111         source access system will be revised soon anyway, and this will
 112         make require behave more like Emacs Lisp's require.  If this
 113         breaks something, please let me know.  Maybe this is real dumb.
 114
 115 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
 116
 117         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
 118         * boot-9.scm: If the `regex' feature is present, use the module
 119         (ice-9 regex).
 120
 121 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
 122
 123         * regex.scm: New file.
 124         * Makefile.am (subpkgdata_DATA): Add regex.scm.
 125         * Makefile.in: Regenerated.
 126
 127 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
 128
 129         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
 130         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
 131         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
 132         threads.scm: New address for FSF.
 133
 134 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
 135
 136         * debug.scm: Update copyright years; this file has been worked on
 137         in 1997.
 138
 139 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
 140
 141         * expect.scm: use gettimeofday instead of get-internal-real-time
 142         and use a floating point timeout when calling select.  Untested,
 143         since the regex library is currently AWOL.
 144
 145 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
 146
 147         * boot-9.scm (eval-string): Function deleted; it was already
 148         implemented in C, so there's no point in making a divergable copy
 149         here.
 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 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 156
 157         * Makefile.in: Regenerated, using automake-1.1p.
 158
 159 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 160
 161         * boot-9.scm (error-catching-loop): don't read a line from
 162         current input when quit is encountered, the previous change
 163         fixes this too.
 164
 165 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
 166
 167         * boot-9.scm (scm-style-repl): After reading an expression,
 168         consume any trailing newline (perhaps preceded by whitespace), to
 169         avoid screwing up GDB.  More detail in comments.
 170
 171 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
 172
 173         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
 174         the Scheme code like code yet.
 175         * Makefile.in: Resrac,husrched.
 176
 177 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 178
 179         * boot-9.scm (link-dynamic-module): Do not catch errors from
 180         dynamic-link and dynamic-call.  When the shared library exists it
 181         is now assumed to be suitable for a dynamic C module.
 182
 183 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 184
 185         * boot-9.scm (process-use-modules): New function to support the
 186         use-modules macro
 187         (use-modules): throw an error iff one of the requested modules
 188         can't be found.
 189
 190 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 191
 192         * boot-9.scm: don't define timer-thunk or gc-thunk.
 193
 194 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 195
 196         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 197
 198         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 199         we're not using AM_INIT_GUILE_MODULE any more.
 200         * Makefile.in: Regeneratitetedrerd.
 201
 202 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 203
 204         Get 'make dist' to work again.
 205         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 206         * Makefile.in: Regenerated, like two tons of fleas.
 207
 208         Changes for reduced Guile distribution: one configure script,
 209         no plugins.
 210         * configure.in, configure: Removed.
 211         * Makefile.in: Regenerated.
 212

 214
 215         * boot-9.scm (eval-string, command-line, load-user-init): New
 216         functions.
 217
 218 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 219
 220         * boot-9.scm (log10): defined.
 221
 222 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 223
 224         * expect.scm (expect-select): correct the millisecond timeout
 225         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 226
 227 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 228
 229         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 230         instead of in libguile.
 231         (tm:sec etc.) new accessors for broken-down time.
 232         (set-tm:sec etc.) new setters for broken-down time.
 233
 234 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 235
 236         * boot-9.scm (netent:addrtype, servent:port): added missing
 237         procedures.
 238         (netent:net, servent:proto): repaired.
 239         (utsname:sysname etc.): new accessors for uname.
 240
 241 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 242
 243         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 244         sockaddr:port): new functions.
 245
 246 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 247
 248         * boot-9.scm: define accessor procedures for the objects returned
 249         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 250         passwd:name, where the first component is the name of the C structure
 251         and the second is the unprefixed C member name.)
 252
 253 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 254
 255         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 256         setservent): no longer take an argument, it was bogus.
 257
 258 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 259
 260         * boot-9.scm (scm-error): deleted, reimplemented in C.
 261
 262 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 263
 264         * boot-9.scm (process-define-module): Modified to handle both
 265         keywords and symbols.
 266
 267 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 268
 269         * slib.scm: update read usage.
 270
 271         * r4rs.scm: update primitive-load usage.
 272         Don't define read-sharp.
 273
 274         * boot-9.scm: use read-hash-extend to install extra read syntax.
 275         (read-sharp): removed.
 276         Adjust usage of primitive-load-path, read, which no longer take
 277         case_i or read-sharp arguments.
 278
 279 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 280
 281         * boot-9.scm: Added loading of session support module.
 282
 283         * debug.scm: Removed `display-application'.  (Replaced by
 284         primitive procedure.)
 285
 286         * boot-9.scm (beautify-user-module!): Don't add the root module
 287         interface to the end of the use-list of the root module.
 288
 289 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 290
 291         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 292
 293 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 294
 295         * boot-9.scm: check use-emacs-interface for emacs support.
 296
 297 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 298
 299         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 300         read gets EOF.
 301         * (exit): alias for quit.
 302
 303 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 304
 305         * boot-9.scm (error-catching-loop thunk): use a status variable to
 306         return the quit args.
 307         (scm-style-repl): call -quit, passing return value from
 308         error-catching-repl.  Make -quit return its args.
 309         stand-alone-repl: comment out, since it seems unused.
 310
 311         (error-catching-loop thunk): discard trailing junk after a (quit).
 312
 313 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 314
 315         * boot-9.scm: Removed the old printer code.
 316
 317         * r4rs.scm (apply, call-with-current-continuation): Added comment
 318         explaining why apply and call/cc need to be closures.
 319
 320         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 321         Removed. These definitions are already present in r4rs.scm.
 322
 323         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 324         stack before printing traced frames; Re-enable trace flag at end
 325         of handlers.
 326
 327 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 328
 329         * debug.scm: Add hook for reset of trace level at abort.
 330
 331         * boot-9.scm (run-hooks): New procedure.
 332         (add-hooks!): New macro.
 333         Change hooks to use these functions.
 334
 335         * debug.scm: *Warning* This feature is a bit premature.  I add
 336         it anyway because 1. it is very useful, and, 2. you can start
 337         making it less premature by complaining to me and by modifying
 338         the source! :-)
 339         (trace): Given one or more procedure objects, trace each one.
 340         Given no arguments, show all traced procedures.
 341         (untrace): Given one or more procedure objects, untrace each one.
 342         Given no arguments, untrace all traced procedures.  The tracing in
 343         Guile have an advantage to most other systems: We don't create new
 344         procedure objects, but mark the procedure objects themselves.
 345         This means that also anonymous and internal procedures can be
 346         traced.
 347
 348         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 349         and exit-frame exceptions.
 350
 351         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 352         (set-repl-prompt!): Setter for repl prompt.
 353         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 354         string, display it; if prompt is a thunk, call it and display its
 355         result; otherwise display "> ".
 356         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 357
 358         * r4rs.scm (%load-verbosely): Reverted change to
 359         `module-defined?', since the module system isn't bootstrapped when
 360         we load r4rs.scm.  This is just a temporary fix to make the

 363 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 364
 365         * boot-9.scm: Removed the enabling of debug evaluator and
 366         recording of source code positions.  This was placed there for our
 367         convenience, but it has already sneaked into the distribution
 368         once... so we'd better add this in our local copies instead when
 369         we need it.  (These options are normally enabled at the end of
 370         boot-9.scm when loading the debug module.)
 371
 372 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 373
 374         * boot-9.scm (module-defined?): New function.
 375         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 376         and eval.
 377         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 378         "defined?".
 379         * slib.scm (defined?): New function to take the place of the
 380         builtin "defined?".  It allways examines the slib module.
 381
 382 Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 383
 384         * configure.in: Added AM_MAINTAINER_MODE
 385
 386 Sat Feb 15 04:51:20 1997  Gary Houston  <ghouston@actrix.gen.nz>
 387
 388         * boot-9.scm (read-sharp): define directly, don't go through a
 389         %read-sharp layer.
 390
 391 Tue Feb 11 08:45:48 1997  Gary Houston  <ghouston@actrix.gen.nz>
 392
 393         * boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
 394         uniform-vector-set1! which doesn't exist.
 395
 396 Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>
 397
 398         * boot-9.scm (backtrace): Removed.  (A C version now exists in
 399         backtrace.c.)
 400
 401 Fri Jan 24 06:05:36 1997  Gary Houston  <ghouston@actrix.gen.nz>
 402
 403         * boot-9.scm (read-line!, read-delimited!, read-delimited,
 404         read-line): new procedures, see libguile/ChangeLog.
 405
 406 Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 407
 408         Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.
 409
 410         * boot-9.scm (split-c-module-name, convert-c-registered-modules,
 411         init-dynamic-module, dynamic-maybe-call,
 412         find-and-link-dynamic-module, link-dynamic-module,
 413         try-module-dynamic-link, registered-modules): New definitions for
 414         dynamic linking of modules.
 415         (resolve-module): Try to dynamically link the requested module
 416         after failing to load it as Scheme code.
 417
 418 Wed Jan  8 05:50:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 419
 420         * boot-9.scm (getservbyport, getservbyname): remove stray %.
 421
 422 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
 423
 424         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
 425         that's what it is.
 426
 427         * lineio.scm (make-line-buffering-input-port): Properly test for
 428         the case of an empty buffer list.  The old code assumed that '()
 429         was false.
 430
 431 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
 432
 433         * boot-9.scm (use-modules): New macro (from Marius Vollmer).
 434         (use-modules <module name> ...) Put the the modules named by
 435         <module name> ... on the use list of the current module.
 436
 437 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
 438
 439         * boot-9.scm (error-catching-loop): Remove message saying that
 440         typing "$" will put you in the debugger.  This isn't implemented
 441         yet.
 442
 443 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
 444
 445         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
 446         been fixed, so this function is superfluous.
 447         (transform-usage-lambda): Use delq!, not delq-all!.
 448
 449 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 450
 451         * boot-9.scm (resolve-module): New optional parameter that
 452         controls whether autoloading is attempted or not. Default is #t.
 453         (process-define-module): Don't autoload the defined module.
 454         (try-module-autoload): Don't autoload the directory modules.
 455
 456         * boot-9.scm (process-define-module): Ensure that the-scm-module
 457         is last in the `uses' list to allow shadowing builtin
 458         bindings. All :use-module options are added in the order they
 459         appear in the arguments but before anything already on the list
 460         (such as the-scm-module).
 461
 462 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
 463
 464         * slib.scm (slib-parent-dir): throw error if #f returned from
 465         %search-load-path.
 466
 467 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
 468
 469         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
 470         * Makefile.am, aclocal.m4: New files.
 471         * configure.in: Updated for Automake.
 472
 473 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
 474
 475         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
 476         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
 477         function, use it accordingly.
 478
 479 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
 480
 481         It's an "eval closure", not an "eval thunk."  A thunk is a
 482         function of no arguments.
 483         * boot-9.scm (module-type): Rename module field.
 484         (make-module, eval-in-module, make-root-module,
 485         set-current-module): Uses changed.
 486         (module-eval-closure, set-module-eval-closure!,
 487         root-module-closure): Renamed from module-eval-thunk,
 488         set-module-eval-thunk!, root-module-thunk.
 489         (set-current-module): Change uses of *top-level-lookup-thunk* to
 490         *top-level-eval-closure*.
 491
 492 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 493
 494         * slib.scm (slib-parent-dir): Use string-length, not length.
 495         (Thanks to Bernard Urban.)
 496
 497 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 498
 499         * boot-9.scm: The debugging evaluator and recording of positions
 500         aren't enabled by default any longer (they are switched on in
 501         debug.scm).  But during development we want to have them also
 502         *inside* boot-9.scm.  Therefore, two lines are added at the
 503         beginning of boot-9.scm to enable these.
 504
 505         Call `provide' so that `records' are included among the
 506         `*features*'.
 507
 508         The scheme for saving the stack has been adjusted: save-stack is
 509         now commonly available for saving the stack.  Calling `save-stack'
 510         sets a flag `stack-saved?' which prevents overwriting the stack.
 511         `stack-saved?' is reset at `abort'.
 512
 513         Spelling correction: seperate --> separate.
 514
 515         Removed `:'s that had creeped into some comments.
 516
 517         The repl now doesn't print #<unspecified> results any longer
 518         If the user wants to see this, he can do
 519         (assert-repl-print-unspecified #t) in his startup file.
 520
 521         The user now gets a friendly message instead of a backtrace at
 522         error.
 523
 524         Added `before-read-hook'.
 525
 526         Load module (ice-9 emacs) if option `-e' was specified.
 527
 528         (provide): New function.
 529
 530         (error): Save stack at entry, so that Guile entrails won't show up
 531         in backtraces.
 532
 533         (backtrace): New function.
 534
 535         (save-stack): Can now take arbitrary number of stack narrowing
 536         specifier pairs.  The first specifier in a pair controls inner
 537         border, the second the outer border.  A number means cut that
 538         number of frames, a procedure object means cut until that object
 539         is found in operator position in a frame.
 540
 541         * debug.scm: Enable debugging evaluator and recording of positions
 542         by default.
 543
 544         * slib.scm (slib:load): Adapt to the new behavior of
 545         primitive-load: It doesn't any longer try both with and without
 546         ".scm" extension.  (We don't want to use %search-load-path here.)
 547
 548         (implementation-vicinity): New function.  slib requires it
 549
 550         (library-vicinity): Updated.
 551
 552         Load "require.scm" in the library-vicinity.
 553
 554         (install-require-vicinity, install-require-module): New functions.
 555
 556 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 557
 558         * boot-9.scm (load-from-path): New function.
 559
 560         * boot-9.scm (try-load, basic-try-load, try-load-module,
 561         try-load): Deleted.  I don't think they're being used.
 562
 563         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 564         so they'll get distributed.
 565
 566         Get Guile to be a little less chatty by default.  The new user
 567         should see as little clutter as possible.
 568         * r4rs.scm (%load-verbosely): Make this #f by default.
 569         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 570         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 571
 572         * r4rs.scm: New file.
 573         * boot-9.scm: Load r4rs.scm, first thing.
 574         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 575         open-output-file, open-io-file, close-input-port,
 576         close-output-port, close-io-port, call-with-input-file,
 577         call-with-output-file, with-input-from-port, with-output-to-port,
 578         with-error-to-port, with-input-from-file, with-output-to-file,
 579         with-error-to-file, with-input-from-string, with-output-to-string,
 580         with-error-to-string, the-eof-object): Definitions moved to
 581         r4rs.scm.  Not all of them are R4RS, but those that are use those
 582         that are not.
 583         (load, %load-verbosely, %load-announce): Moved, along with code to
 584         set %load-hook, to r4rs.scm.
 585
 586         * test.scm: New file.
 587
 588         * boot-9.scm (integer?): Definition deleted, in favor of the one
 589         present in libguile (which used to be called int?).  I have no
 590         idea why integer? didn't just call int? to begin with.
 591
 592         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 593         =?, >?, and >=? deleted; they're defined that way by libguile now.
 594
 595         * boot-9.scm (load): Simplified; primitive-load does most of this
 596         work now.
 597         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 598         call %load-announce.
 599
 600 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 601
 602         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 603         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 604         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 605         components.
 606         (file-is-directory?): use stat:type.
 607
 608 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 609
 610         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 611         that's now taken care of in libguile, and in a way compatible with
 612         SCSH (which this isn't).
 613
 614 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 615
 616         * boot-9.scm: Formatting tweaks.
 617
 618 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 619
 620         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 621         after-error-hook, before-backtrace-hook and after-backtrace-hook
 622         to the error handler.  E.g.: fancy emacs support could plug into
 623         these.
 624         (save-stack): New function.  The stack is now made differently
 625         depending on the stack id.  (The motivation is to make a better
 626         choice regarding what stack frames to present to the user.)
 627         (error-catching-loop): Stack handling code moved outside into
 628         save-stack.
 629
 630 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 631
 632         * Makefile.in (scm_files): add expect.scm.
 633
 634         * expect.scm: new file ported from guile-iii.
 635
 636         * boot-9.scm: remove handle-system-error, after moving the code into
 637         error-catching-loop.
 638         Don't set 'throw-handler-default property on error keys.
 639         Just interpret (almost) any throw with 4 args as an error throw.
 640         Delete some try-load stuff that was already commented out.
 641
 642         Second thoughts, keep handle-system-error but call it from
 643         error-catching-loop.
 644
 645 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 646
 647         * boot-9.scm: Doc fixes.
 648         (make-module): Rework for readability.
 649         (make-root-module, make-scm-module): USES argument to make-module
 650         should be '(), not #f.
 651
 652         * boot-9.scm (try-load): %sys-load-path has been renamed to
 653         primitive-load-path; adjust call here.
 654
 655 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 656
 657         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 658         the stack to the correct place: when it is decided to generate an
 659         error-signal.
 660
 661 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 662
 663         * boot-9.scm (error-catching-loop, signal-handler,
 664         handle-system-error): Backtracing now works for signals aswell;
 665         Backtracing mechanism can now identify the stack root created by
 666         start-stack so that the user isn't exposed to system stack frames.
 667
 668 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 669
 670         * Makefile.in: Added threads.scm.
 671
 672 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 673
 674         * debug.scm (make-enable, make-disable): Simplified.
 675
 676         * boot-9.scm: Renamed %%throw-handler-default -->
 677         throw-handler-default.
 678         ((handle-system-error key . arg-list)): Changed the way errors are
 679         reported.
 680         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 681         acro.
 682         ((error-catching-loop thunk)): Introduce a lazy-catch into
 683         error-catching-loop so that the stack can be captured.
 684
 685 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 686
 687         * mapping.scm (hash-table-mapping): Explicitly request that
 688         make-vector fill new vectors with '(); this will make it easier to
 689         port Guile Scheme code to other Schemes.
 690         * boot-9.scm (make-print-style, make-print-table): Same.
 691
 692 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 693
 694         * boot-9.scm (load): rewritten again.
 695         Append "." to the default %load-path.
 696         (feature?): new function: checks for a symbol in the features list.
 697         (module-local-variable): remove apparently useless (caddr (list m v
 698         ...))
 699         (%load-announce): minor formatting change.
 700         (file-exists?): use access? if posix is featured.
 701         (file-is-directory?): use stat if i/o-extensions is featured.
 702         (try-module-autoload module-name): use file-exists? before
 703         file-is-directory?
 704
 705 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 706
 707         * boot-9.scm: Added conditional loading of threads.scm.
 708
 709         * threads.scm: New file.  Modified from the Cygnus-r0.3
 710         distribution.
 711
 712         * boot-9.scm (error-catching-loop): Added handling of key
 713         `switch-repl'.
 714
 715         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 716
 717 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 718
 719         * boot-9.scm (make-record-type, record-constructor): Don't assume

 722 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 723
 724         * boot-9.scm (signal-handler): Clean up logic.
 725
 726         * boot-9.scm (load): Assume %load-path is always bound.
 727
 728 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 729
 730         * boot-9.scm (error): replace another throw with scm-error.  Throw
 731         to 'misc-error instead of 'error (no need to distinguish these.)
 732         Don't set up 'error as a key.
 733         Set up regex-error as a key, if regex is available.
 734         (signal-handler): use scm-error, not throw.
 735
 736         (%try-load, try-load-with-path, %load, load-with-path,
 737         basic-try-load-with-path, basic-load-with-path,
 738         try-load-module-with-path,load-module-with-path): deleted, since
 739         they seem redundant.
 740         (try-load): define using %try-load, not try-load-with-path.
 741         (load): rewritten.  load tries to open the file directly and
 742         with a .scm extension before searching the library directories
 743         (should "." be added to %load-path?  then load could still open
 744         directly files starting with "/").
 745         (try-module-autoload): use load, not load-with-path.
 746         (%load-indent): deleted, -2 was causing errors.
 747
 748         (%read-sharp): use port-line, not line-number.
 749
 750 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 751
 752         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 753         straightforward to provide the equivalent functionality using
 754         (catch #t ...), so there's no need for the extra complexity.  2)
 755         Outside the context of a read-eval-print loop (which Guile should
 756         not require) it's not clear we should do anything more complicated
 757         than print an error and exit; the user or REPL can establish
 758         something better if it wants.  3) In that case, it's much more
 759         robust to just do it in the C code.

 761 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 762
 763         * boot-9.scm (%try-load): define using primitive-load.  Previously
 764         %try-load itself was the primitive.
 765         (load-with-path): use scm-error instead of %load-announce-lossage.
 766         Errors are thrown to 'misc-error instead of 'could-not-load.
 767         (%load-announce-lossage): deleted.
 768
 769 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 770
 771         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 772         (make-record-type type-name fields): Temporarily remove support
 773         for printing of records (not possible yet with C printer).
 774
 775 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 776
 777         * boot-9.scm (file-exists?, file-is-directory): catch only
 778         system-error, not every kind of error.
 779         (scm-error): new procedure.
 780
 781 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>

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

 833         * boot-9.scm (%%handle-system-error): recognise errors thrown
 834         by lgh-error (fill-message etc.)
 835         (fill-message): check first whether args is null.
 836         (fill-message): bug fix and check that args is a list.

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

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

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