ice-9/ChangeLog

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

 202
 203         * boot-9.scm (eval-string, command-line, load-user-init): New
 204         functions.
 205
 206 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 207
 208         * boot-9.scm (log10): defined.
 209
 210 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 211
 212         * expect.scm (expect-select): correct the millisecond timeout
 213         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 214
 215 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 216
 217         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 218         instead of in libguile.
 219         (tm:sec etc.) new accessors for broken-down time.
 220         (set-tm:sec etc.) new setters for broken-down time.
 221
 222 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 223
 224         * boot-9.scm (netent:addrtype, servent:port): added missing
 225         procedures.
 226         (netent:net, servent:proto): repaired.
 227         (utsname:sysname etc.): new accessors for uname.
 228
 229 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 230
 231         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 232         sockaddr:port): new functions.
 233
 234 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 235
 236         * boot-9.scm: define accessor procedures for the objects returned
 237         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 238         passwd:name, where the first component is the name of the C structure
 239         and the second is the unprefixed C member name.)
 240
 241 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 242
 243         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 244         setservent): no longer take an argument, it was bogus.
 245
 246 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 247
 248         * boot-9.scm (scm-error): deleted, reimplemented in C.
 249
 250 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 251
 252         * boot-9.scm (process-define-module): Modified to handle both
 253         keywords and symbols.
 254
 255 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 256
 257         * slib.scm: update read usage.
 258
 259         * r4rs.scm: update primitive-load usage.
 260         Don't define read-sharp.
 261
 262         * boot-9.scm: use read-hash-extend to install extra read syntax.
 263         (read-sharp): removed.
 264         Adjust usage of primitive-load-path, read, which no longer take
 265         case_i or read-sharp arguments.
 266
 267 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 268
 269         * boot-9.scm: Added loading of session support module.
 270
 271         * debug.scm: Removed `display-application'.  (Replaced by
 272         primitive procedure.)
 273
 274         * boot-9.scm (beautify-user-module!): Don't add the root module
 275         interface to the end of the use-list of the root module.
 276
 277 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 278
 279         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 280
 281 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 282
 283         * boot-9.scm: check use-emacs-interface for emacs support.
 284
 285 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 286
 287         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 288         read gets EOF.
 289         * (exit): alias for quit.
 290
 291 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 292
 293         * boot-9.scm (error-catching-loop thunk): use a status variable to
 294         return the quit args.
 295         (scm-style-repl): call -quit, passing return value from
 296         error-catching-repl.  Make -quit return its args.
 297         stand-alone-repl: comment out, since it seems unused.
 298
 299         (error-catching-loop thunk): discard trailing junk after a (quit).
 300
 301 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 302
 303         * boot-9.scm: Removed the old printer code.
 304
 305         * r4rs.scm (apply, call-with-current-continuation): Added comment
 306         explaining why apply and call/cc need to be closures.
 307
 308         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 309         Removed. These definitions are already present in r4rs.scm.
 310
 311         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 312         stack before printing traced frames; Re-enable trace flag at end
 313         of handlers.
 314
 315 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 316
 317         * debug.scm: Add hook for reset of trace level at abort.
 318
 319         * boot-9.scm (run-hooks): New procedure.
 320         (add-hooks!): New macro.
 321         Change hooks to use these functions.
 322
 323         * debug.scm: *Warning* This feature is a bit premature.  I add
 324         it anyway because 1. it is very useful, and, 2. you can start
 325         making it less premature by complaining to me and by modifying
 326         the source! :-)
 327         (trace): Given one or more procedure objects, trace each one.
 328         Given no arguments, show all traced procedures.
 329         (untrace): Given one or more procedure objects, untrace each one.
 330         Given no arguments, untrace all traced procedures.  The tracing in
 331         Guile have an advantage to most other systems: We don't create new
 332         procedure objects, but mark the procedure objects themselves.
 333         This means that also anonymous and internal procedures can be
 334         traced.
 335
 336         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 337         and exit-frame exceptions.
 338
 339         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 340         (set-repl-prompt!): Setter for repl prompt.
 341         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 342         string, display it; if prompt is a thunk, call it and display its
 343         result; otherwise display "> ".
 344         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 345
 346         * r4rs.scm (%load-verbosely): Reverted change to
 347         `module-defined?', since the module system isn't bootstrapped when
 348         we load r4rs.scm.  This is just a temporary fix to make the
 349         repository version runnable.
 350
 351 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 352
 353         * boot-9.scm: Removed the enabling of debug evaluator and
 354         recording of source code positions.  This was placed there for our
 355         convenience, but it has already sneaked into the distribution
 356         once... so we'd better add this in our local copies instead when
 357         we need it.  (These options are normally enabled at the end of
 358         boot-9.scm when loading the debug module.)
 359

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

 739
 740         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 741         straightforward to provide the equivalent functionality using
 742         (catch #t ...), so there's no need for the extra complexity.  2)
 743         Outside the context of a read-eval-print loop (which Guile should
 744         not require) it's not clear we should do anything more complicated
 745         than print an error and exit; the user or REPL can establish
 746         something better if it wants.  3) In that case, it's much more
 747         robust to just do it in the C code.

 750
 751         * boot-9.scm (%try-load): define using primitive-load.  Previously
 752         %try-load itself was the primitive.
 753         (load-with-path): use scm-error instead of %load-announce-lossage.
 754         Errors are thrown to 'misc-error instead of 'could-not-load.
 755         (%load-announce-lossage): deleted.

 761         for printing of records (not possible yet with C printer).

 766         system-error, not every kind of error.
 767         (scm-error): new procedure.

 777         of args are supplied.
 778         (%%system-errors): removed.
 779         (error): redefine using a throw with key and 4 args.
 780         ('error): associate 'error, 'error-signal keys with
 781         %%handle-system-error.
 782         (%%default-error-handler): removed.
 783         (signal-handler): throw with 4 args and use the error-signal key.
 784         Create an error message instead of using numerical codes.
 785         (%%bad-throw): call error instead of throw if key not found.

 787 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 788
 789         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 790         (%%handle-system-error key): check subr is not #f before printing.
 791         Recognize %s (embed an argument using "display") and
 792         %S (embed an argument using "write").

 803
 804         * boot-9.scm: remove leading %% from references to '%%system-error.
 805         (%%handle-system-error): don't pass all the thrown arguments when
 806         aborting, just the key and subr.
 807         Remove the code to "Install default handlers for built-in errors."
 808         Remove the definition of the syserror procedure.
 809         Associate 'numerical-overflow with default handler.

 812
 813         * boot-9.scm: Name change: value-ref --> local-ref
 814         resolved-ref --> nested-ref  Motivation: conformance to the other
 815         dictionary operators: list-ref operates on list, vector-ref
 816         operates on vector, nested-ref operates on nested namespace,
 817         local-ref operates on the local nested namespace.

 831
 832         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 833         "/", use one to separate it from the file.

 836
 837         * boot-9.scm (%load-path): Add the site directory.
 838         Add the directory named after the version number.
 839         Prepend the version number to the other directories in the path.

 850         Don't use the PLUGIN system to gather information for the
 851         Makefile's distribution and installation targets; just put it all
 852         in the Makefile directly.
 853         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 854         for these.
