ice-9/ChangeLog

   1 Mon Jun 23 16:13:38 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 (make-list): Remove the definition of this function
   8         from the (ice-9 common-list) module; make the `init' argument
   9         optional in the scm module's definition, to match the deleted
  10         definition.  Harmony reigneth?  (Thanks to Bernard URBAN.)

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  49         * boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated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

 194
 195         * boot-9.scm (eval-string, command-line, load-user-init): New
 196         functions.
 197
 198 Sat Apr 12 08:27:05 1997  Gary Houston  <ghouston@actrix.gen.nz>
 199
 200         * boot-9.scm (log10): defined.
 201
 202 Tue Apr  1 17:46:49 1997  Gary Houston  <ghouston@actrix.gen.nz>
 203
 204         * expect.scm (expect-select): correct the millisecond timeout
 205         arithmetic (from Marko.Kohtala@ntc.nokia.com).
 206
 207 Mon Mar 31 03:23:19 1997  Gary Houston  <ghouston@actrix.gen.nz>
 208
 209         * boot-9.scm (open-input-pipe, open-output-pipe): defined here
 210         instead of in libguile.
 211         (tm:sec etc.) new accessors for broken-down time.
 212         (set-tm:sec etc.) new setters for broken-down time.
 213
 214 Thu Mar 27 05:06:00 1997  Gary Houston  <ghouston@actrix.gen.nz>
 215
 216         * boot-9.scm (netent:addrtype, servent:port): added missing
 217         procedures.
 218         (netent:net, servent:proto): repaired.
 219         (utsname:sysname etc.): new accessors for uname.
 220
 221 Tue Mar 25 03:04:03 1997  Gary Houston  <ghouston@actrix.gen.nz>
 222
 223         * boot-9.scm (sockaddr:fam, sockaddr:path, sockaddr:addr,
 224         sockaddr:port): new functions.
 225
 226 Wed Mar 19 04:50:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 227
 228         * boot-9.scm: define accessor procedures for the objects returned
 229         by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
 230         passwd:name, where the first component is the name of the C structure
 231         and the second is the unprefixed C member name.)
 232
 233 Tue Mar 18 18:39:31 1997  Gary Houston  <ghouston@actrix.gen.nz>
 234
 235         * boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
 236         setservent): no longer take an argument, it was bogus.
 237
 238 Thu Mar 13 00:13:41 1997  Gary Houston  <ghouston@actrix.gen.nz>
 239
 240         * boot-9.scm (scm-error): deleted, reimplemented in C.
 241
 242 Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 243
 244         * boot-9.scm (process-define-module): Modified to handle both
 245         keywords and symbols.
 246
 247 Sat Mar  8 04:32:44 1997  Gary Houston  <ghouston@actrix.gen.nz>
 248
 249         * slib.scm: update read usage.
 250
 251         * r4rs.scm: update primitive-load usage.
 252         Don't define read-sharp.
 253
 254         * boot-9.scm: use read-hash-extend to install extra read syntax.
 255         (read-sharp): removed.
 256         Adjust usage of primitive-load-path, read, which no longer take
 257         case_i or read-sharp arguments.
 258
 259 Sat Mar  8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 260
 261         * boot-9.scm: Added loading of session support module.
 262
 263         * debug.scm: Removed `display-application'.  (Replaced by
 264         primitive procedure.)
 265
 266         * boot-9.scm (beautify-user-module!): Don't add the root module
 267         interface to the end of the use-list of the root module.
 268
 269 Thu Mar  6 07:26:34 1997  Gary Houston  <ghouston@actrix.gen.nz>
 270
 271         * boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.
 272
 273 Wed Mar  5 20:30:24 1997  Gary Houston  <ghouston@actrix.gen.nz>
 274
 275         * boot-9.scm: check use-emacs-interface for emacs support.
 276
 277 Sun Mar  2 19:47:14 1997  Gary Houston  <ghouston@actrix.gen.nz>
 278
 279         * boot-9.scm (scm-style-repl): call repl-report-start-timing if
 280         read gets EOF.
 281         * (exit): alias for quit.
 282
 283 Sun Mar  2 05:25:11 1997  Gary Houston  <ghouston@actrix.gen.nz>
 284
 285         * boot-9.scm (error-catching-loop thunk): use a status variable to
 286         return the quit args.
 287         (scm-style-repl): call -quit, passing return value from
 288         error-catching-repl.  Make -quit return its args.
 289         stand-alone-repl: comment out, since it seems unused.
 290
 291         (error-catching-loop thunk): discard trailing junk after a (quit).
 292
 293 Sat Mar  1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 294
 295         * boot-9.scm: Removed the old printer code.
 296
 297         * r4rs.scm (apply, call-with-current-continuation): Added comment
 298         explaining why apply and call/cc need to be closures.
 299
 300         * boot-9.scm (apply, call-with-current-continuation): Bugfix:
 301         Removed. These definitions are already present in r4rs.scm.
 302
 303         * debug.scm (trace-entry, trace-exit): Check that we're on a repl
 304         stack before printing traced frames; Re-enable trace flag at end
 305         of handlers.
 306
 307 Sat Mar  1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 308
 309         * debug.scm: Add hook for reset of trace level at abort.
 310
 311         * boot-9.scm (run-hooks): New procedure.
 312         (add-hooks!): New macro.
 313         Change hooks to use these functions.
 314
 315         * debug.scm: *Warning* This feature is a bit premature.  I add
 316         it anyway because 1. it is very useful, and, 2. you can start
 317         making it less premature by complaining to me and by modifying
 318         the source! :-)
 319         (trace): Given one or more procedure objects, trace each one.
 320         Given no arguments, show all traced procedures.
 321         (untrace): Given one or more procedure objects, untrace each one.
 322         Given no arguments, untrace all traced procedures.  The tracing in
 323         Guile have an advantage to most other systems: We don't create new
 324         procedure objects, but mark the procedure objects themselves.
 325         This means that also anonymous and internal procedures can be
 326         traced.
 327
 328         * boot-9.scm (error-catching-loop): Added handling of apply-frame
 329         and exit-frame exceptions.
 330
 331         * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
 332         (set-repl-prompt!): Setter for repl prompt.
 333         (scm-style-repl): If prompt is #f, don't prompt; if prompt is a
 334         string, display it; if prompt is a thunk, call it and display its
 335         result; otherwise display "> ".
 336         (Change suggested by Roland Orre <orre@nada.kth.se>.)
 337
 338         * r4rs.scm (%load-verbosely): Reverted change to
 339         `module-defined?', since the module system isn't bootstrapped when
 340         we load r4rs.scm.  This is just a temporary fix to make the
 341         repository version runnable.
 342
 343 Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 344
 345         * boot-9.scm: Removed the enabling of debug evaluator and
 346         recording of source code positions.  This was placed there for our
 347         convenience, but it has already sneaked into the distribution
 348         once... so we'd better add this in our local copies instead when
 349         we need it.  (These options are normally enabled at the end of
 350         boot-9.scm when loading the debug module.)
 351
 352 Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>
 353
 354         * boot-9.scm (module-defined?): New function.
 355         (macroexpand-1, macroexpand): Use local-ref instead of defined?
 356         and eval.
 357         * r4rs.scm (%load-verbosely): Use "module-defined?" instead of
 358         "defined?".
 359         * slib.scm (defined?): New function to take the place of the
 360         builtin "defined?".  It allways examines the slib module.

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

 731
 732         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 733         straightforward to provide the equivalent functionality using
 734         (catch #t ...), so there's no need for the extra complexity.  2)
 735         Outside the context of a read-eval-print loop (which Guile should
 736         not require) it's not clear we should do anything more complicated
 737         than print an error and exit; the user or REPL can establish
 738         something better if it wants.  3) In that case, it's much more
 739         robust to just do it in the C code.

 743         * boot-9.scm (%try-load): define using primitive-load.  Previously

 746         Errors are thrown to 'misc-error instead of 'could-not-load.
 747         (%load-announce-lossage): deleted.

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

 771         (error): redefine using a throw with key and 4 args.
 772         ('error): associate 'error, 'error-signal keys with
 773         %%handle-system-error.
 774         (%%default-error-handler): removed.
 775         (signal-handler): throw with 4 args and use the error-signal key.
 776         Create an error message instead of using numerical codes.
 777         (%%bad-throw): call error instead of throw if key not found.

 780
 781         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 782         (%%handle-system-error key): check subr is not #f before printing.
 783         Recognize %s (embed an argument using "display") and
 784         %S (embed an argument using "write").

 797         (%%handle-system-error): don't pass all the thrown arguments when

 804
 805         * boot-9.scm: Name change: value-ref --> local-ref
 806         resolved-ref --> nested-ref  Motivation: conformance to the other
 807         dictionary operators: list-ref operates on list, vector-ref
 808         operates on vector, nested-ref operates on nested namespace,
 809         local-ref operates on the local nested namespace.

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

 846         for these.
