   1 Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
   2
   3         * boot-9.scm: If using emacs interface, enable backtraces
   4         automatically.
   5
   6 Mon Jul 21 06:45:45 1997  Gary Houston  <ghouston@actrix.gen.nz>
   7
   8         * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
   9         dup, fdes->inport, fdes->outport, port->fdes): new procedures.
  10         (duplicate-port): was a C primitive, now it's here.
  11         (move->fdes): allow the first argument to be a file descriptor.
  12         Return the modified port or file descriptor (was unspecified.)
  13
  14 Fri Jul 11 00:13:43 1997  Jim Blandy  <jimb@floss.red-bean.com>
  15
  16         Changes to compile under gnu-win32, from Marcus Daniels:
  17         * boot-9.scm (load-user-init): If HOME is unset, provide
  18         a default of /.
  19
  20         * boot-9.scm (define-public): Changed to accomodate Hobbit.
  21
  22 Tue Jun 24 00:31:47 1997  Jim Blandy  <jimb@floss.red-bean.com>
  23
  24         * boot-9.scm, debug.scm, hcons.scm, lineio.scm, mapping.scm,
  25         poe.scm, slib.scm, tags.scm, threads.scm: Use normal list
  26         notation, instead of #/ notation.
  27
  28         * expect.scm (expect-strings): Pass regexp/newline flag to
  29         make-regexp.
  30
  31 Mon Jun 23 16:13:38 1997  Jim Blandy  <jimb@floss.red-bean.com>
  32
  33         Fix inconsistencies in parsing of #/ style lists.
  34         * boot-9.scm (read-path-list-notation): New function.
  35         (parse-path-symbol): Deleted.  Replaced by above.
  36         Plug in read-path-list-notation as the parser for #/ lists,
  37         instead of the anonymous lambda form calling parse-path-symbol.
  38         (Thanks to Maurizio Vitale.)
  39
  40         * boot-9.scm (make-list): Remove the definition of this function
  41         from the (ice-9 common-list) module; make the `init' argument
  42         optional in the scm module's definition, to match the deleted
  43         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)
  44
  45 Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>
  46
  47         Try to detect when people are using one version of libguile and a
  48         different version of ice-9.  People have been skewing things and
  49         sending in bug reports.
  50         * version.scm.in: New file, which the configure script munges to
  51         produce version.scm, which contains the ice-9 config stamp.
  52         * boot-9.scm: Compare the libguile and ice-9 config stamps;
  53         display a warning if the two are different.
  54         * Makefile.am: Install version.scm, but don't distribute it.
  55         Distribute version.scm.in, but don't install it.
  56         * Makefile.in: Regenerated.
  57
  58 Thu Jun 19 21:01:16 1997  Jim Blandy  <jimb@floss.red-bean.com>
  59
  60         * slib.scm (slib:warn): Alias for WARN function.
  61
  62 Fri Jun 13 00:32:04 1997  Jim Blandy  <jimb@floss.red-bean.com>
  63
  64         * boot-9.scm (struct-printer): Fix off-by-one error in range
  65         check.  Correctly check for struct printer tag.
  66
  67         * expect.scm: Turn this into a module, (ice-9 expect).
  68         (expect-port, expect-timeout, expect-timeout-proc,
  69         expect-eof-proc, expect-char-proc, expect, expect-strings,
  70         expect-select): Make these public definitions.
  71         (expect-strings): Use make-regexp and regexp-exec, instead of
  72         regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
  73         that's okay.
  74
  75         * boot-9.scm (with-regexp-parts): Comment this out.  It has no
  76         users in the core, and relies on mildly hairy details of the old
  77         regexp interface.
  78
  79         * test.scm: Re-enable tests asserting that '() is true, and not a
  80         boolean.  This stuff has been true for a while.
  81
  82         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated
  83         function names.
  84
  85         * boot-9.scm (with-excursion-getter-and-setter, q-rear): Doc
  86         fixes.
  87
  88 Wed Jun 11 00:31:40 1997  Jim Blandy  <jimb@floss.red-bean.com>
  89
  90         * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
  91         ../configure.in.
  92
  93 Fri Jun  6 14:37:18 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  94
  95         * boot-9.scm (struct-printer): Bugfix: Check the layout of the
  96         vtable and not the one of the struct.
  97
  98 Wed Jun  4 23:27:16 1997  Marius Vollmer  <mvo@zagadka.ping.de>
  99
 100         * boot-9.scm (struct-layout, %struct-printer-tag, struct-printer,
 101         make-struct-printer, set-struct-printer-in-vtable!): New bindings
 102         to support printing of structures.
 103         (record-type-vtable, make-record-type): Add slot to hold printing
 104         function and initialize it with something appropriate.  Removed
 105         commented out printing code.
 106         (record-type-name, record-type-fields): Adjusted slot offsets.
 107         (%print-module): Reduce argument list to "mod" and "port".
 108
 109 Tue Jun  3 17:04:18 1997  Jim Blandy  <jimb@totoro.cyclic.com>
 110
 111         * slib.scm (identity): New function, used by SLIB.
 112
 113 Sat May 31 18:57:12 1997  Gary Houston  <ghouston@actrix.gen.nz>
 114
 115         * boot-9.scm: signal-handler, alarm-thunk: removed.
 116         don't define ticks-interrupt etc.
 117         top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
 118         during call to scm-style-repl.
 119
 120 Fri May 30 18:08:10 1997  Jim Blandy  <jimb@floss.cyclic.com>
 121
 122         * slib.scm (slib:load): Use primitive-load-path instead of
 123         basic-load.  This is probably wrong, but hopefully the entire
 124         source access system will be revised soon anyway, and this will
 125         make require behave more like Emacs Lisp's require.  If this
 126         breaks something, please let me know.  Maybe this is real dumb.
 127
 128 Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>
 129
 130         * regex.scm: Add a module declaration.  Use DEFINE-PUBLIC everywhere.
 131         * boot-9.scm: If the `regex' feature is present, use the module
 132         (ice-9 regex).
 133
 134 Tue May 27 22:48:14 1997  Tim Pierce  <twp@twp.tezcat.com>
 135
 136         * regex.scm: New file.
 137         * Makefile.am (subpkgdata_DATA): Add regex.scm.
 138         * Makefile.in: Regenerated.
 139
 140 Mon May 26 17:24:48 1997  Jim Blandy  <jimb@totoro.cyclic.com>
 141
 142         * COPYING, boot-9.scm, debug.scm, emacs.scm, expect.scm, gtcl.scm,
 143         gwish.scm, hcons.scm, lineio.scm, mapping.scm, nonblocking.scm,
 144         oldprint.scm, poe.scm, r4rs.scm, source.scm, tags.scm, test.scm,
 145         threads.scm: New address for FSF.
 146
 147 Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>
 148
 149         * debug.scm: Update copyright years; this file has been worked on
 150         in 1997.
 151
 152 Thu May 15 07:56:08 1997  Gary Houston  <ghouston@actrix.gen.nz>
 153
 154         * expect.scm: use gettimeofday instead of get-internal-real-time
 155         and use a floating point timeout when calling select.  Untested,
 156         since the regex library is currently AWOL.
 157
 158 Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>
 159
 160         * boot-9.scm (eval-string): Function deleted; it was already
 161         implemented in C, so there's no point in making a divergable copy
 162         here.
 163
 164 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 165
 166         * Makefile.in: Regenerated, using automake-1.1p.
 167
 168 Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>
 169
 170         * Makefile.in: Regenerated, using automake-1.1p.
 171
 172 Tue May 13 02:48:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 173
 174         * boot-9.scm (error-catching-loop): don't read a line from
 175         current input when quit is encountered, the previous change
 176         fixes this too.
 177
 178 Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>
 179
 180         * boot-9.scm (scm-style-repl): After reading an expression,
 181         consume any trailing newline (perhaps preceded by whitespace), to
 182         avoid screwing up GDB.  More detail in comments.
 183
 184 Mon May  5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>
 185
 186         * Makefile.am (ETAGS_ARGS): New variable, since we're not treating
 187         the Scheme code like code yet.
 188         * Makefile.in: Resrac,husrched.
 189
 190 Wed Apr 30 15:25:15 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 191
 192         * boot-9.scm (link-dynamic-module): Do not catch errors from
 193         dynamic-link and dynamic-call.  When the shared library exists it
 194         is now assumed to be suitable for a dynamic C module.
 195
 196 Fri Apr 25 21:21:35 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 197
 198         * boot-9.scm (process-use-modules): New function to support the
 199         use-modules macro
 200         (use-modules): throw an error iff one of the requested modules
 201         can't be found.
 202
 203 Tue Apr 29 06:54:46 1997  Gary Houston  <ghouston@actrix.gen.nz>
 204
 205         * boot-9.scm: don't define timer-thunk or gc-thunk.
 206
 207 Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>
 208
 209         * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
 210
 211         * Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
 212         we're not using AM_INIT_GUILE_MODULE any more.
 213         * Makefile.in: Regeneratitetedrerd.
 214
 215 Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>
 216
 217         Get 'make dist' to work again.
 218         * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
 219         * Makefile.in: Regenerated, like two tons of fleas.
 220
 221         Changes for reduced Guile distribution: one configure script,
 222         no plugins.
 223         * configure.in, configure: Removed.
 224         * Makefile.in: Regenerated.
 225

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

 719
 720         * boot-9.scm: Added conditional loading of threads.scm.
 721
 722         * threads.scm: New file.  Modified from the Cygnus-r0.3
 723         distribution.
 724
 725         * boot-9.scm (error-catching-loop): Added handling of key
 726         `switch-repl'.
 727
 728         * boot-9.scm: Name change %%bad-throw --> bad-throw.

 730 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 731
 732         * boot-9.scm (make-record-type, record-constructor): Don't assume
 733         the empty list is false when parsing the argument list.
 734
 735 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 736
 737         * boot-9.scm (signal-handler): Clean up logic.
 738
 739         * boot-9.scm (load): Assume %load-path is always bound.
 740
 741 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 742
 743         * boot-9.scm (error): replace another throw with scm-error.  Throw
 744         to 'misc-error instead of 'error (no need to distinguish these.)
 745         Don't set up 'error as a key.
 746         Set up regex-error as a key, if regex is available.
 747         (signal-handler): use scm-error, not throw.
 748
 749         (%try-load, try-load-with-path, %load, load-with-path,
 750         basic-try-load-with-path, basic-load-with-path,
 751         try-load-module-with-path,load-module-with-path): deleted, since
 752         they seem redundant.
 753         (try-load): define using %try-load, not try-load-with-path.
 754         (load): rewritten.  load tries to open the file directly and
 755         with a .scm extension before searching the library directories
 756         (should "." be added to %load-path?  then load could still open
 757         directly files starting with "/").
 758         (try-module-autoload): use load, not load-with-path.
 759         (%load-indent): deleted, -2 was causing errors.
 760
 761         (%read-sharp): use port-line, not line-number.
 762
 763 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 764
 765         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 766         straightforward to provide the equivalent functionality using
 767         (catch #t ...), so there's no need for the extra complexity.  2)
 768         Outside the context of a read-eval-print loop (which Guile should
 769         not require) it's not clear we should do anything more complicated
 770         than print an error and exit; the user or REPL can establish
 771         something better if it wants.  3) In that case, it's much more
 772         robust to just do it in the C code.
 773
 774 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 775
 776         * boot-9.scm (%try-load): define using primitive-load.  Previously
 777         %try-load itself was the primitive.
 778         (load-with-path): use scm-error instead of %load-announce-lossage.
 779         Errors are thrown to 'misc-error instead of 'could-not-load.
 780         (%load-announce-lossage): deleted.
 781
 782 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 783
 784         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 785         (make-record-type type-name fields): Temporarily remove support
 786         for printing of records (not possible yet with C printer).
 787
 788 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 789
 790         * boot-9.scm (file-exists?, file-is-directory): catch only
 791         system-error, not every kind of error.
 792         (scm-error): new procedure.
 793
 794 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 795
 796         * boot-9.scm: Formatting tweaks.
 797
 798 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 799
 800         * boot-9.scm (%%handle-system-error key): remove the code for
 801         SCM-style errors.  handle the case that an unexpected number
 802         of args are supplied.
 803         (%%system-errors): removed.
 804         (error): redefine using a throw with key and 4 args.
 805         ('error): associate 'error, 'error-signal keys with
 806         %%handle-system-error.
 807         (%%default-error-handler): removed.
 808         (signal-handler): throw with 4 args and use the error-signal key.
 809         Create an error message instead of using numerical codes.
 810         (%%bad-throw): call error instead of throw if key not found.
 811
 812 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 813
 814         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 815         (%%handle-system-error key): check subr is not #f before printing.
 816         Recognize %s (embed an argument using "display") and
 817         %S (embed an argument using "write").
 818
 819 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 820
 821         * boot-9.scm (%%handle-system-error key): set args and rest to
 822         the empty list if they are #f.
 823         Initialize out-of-range as an error key.
 824
 825 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 826
 827         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 828
 829         * boot-9.scm: remove leading %% from references to '%%system-error.
 830         (%%handle-system-error): don't pass all the thrown arguments when
 831         aborting, just the key and subr.
 832         Remove the code to "Install default handlers for built-in errors."
 833         Remove the definition of the syserror procedure.
 834         Associate 'numerical-overflow with default handler.
 835
 836 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 837
 838         * boot-9.scm: Name change: value-ref --> local-ref
 839         resolved-ref --> nested-ref  Motivation: conformance to the other
 840         dictionary operators: list-ref operates on list, vector-ref
 841         operates on vector, nested-ref operates on nested namespace,
 842         local-ref operates on the local nested namespace.
 843
 844 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 845
 846         * boot-9.scm (%%handle-system-error): recognise errors thrown

 852
 853         * boot-9.scm: %load-path is initialized in C code now.
 854         (implementation-vicinity, parse-path): Deleted, along with code to
 855         initialize %load-path.
 856
 857         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 858         "/", use one to separate it from the file.
 859
 860 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 861
 862         * boot-9.scm (%load-path): Add the site directory.
 863         Add the directory named after the version number.
 864         Prepend the version number to the other directories in the path.
 865         Simplify by mapping the common prefix onto each item.

 874
 875         Don't use the PLUGIN system to gather information for the
 876         Makefile's distribution and installation targets; just put it all
 877         in the Makefile directly.
 878         * PLUGIN/this.configure (scm_files, aux_files): Remove sections
 879         for these.
 880         * configure.in: Remove code that gets and substitutes scm_files and
 881         aux_files.

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