ice-9/ChangeLog

   1 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
   2
   3 *       * boot-9.scm: The debugging evaluator and recording of positions
   4         aren't enabled by default any longer (they are switched on in
   5         debug.scm).  But during development we want to have them also
   6         *inside* boot-9.scm.  Therefore, two lines are added at the
   7         beginning of boot-9.scm to enable these.
   8
   9         Call `provide' so that `records' are included among the
  10         `*features*'.
  11
  12         The scheme for saving the stack has been adjusted: save-stack is
  13         now commonly available for saving the stack.  Calling `save-stack'
  14         sets a flag `stack-saved?' which prevents overwriting the stack.
  15         `stack-saved?' is reset at `abort'.
  16
  17         Spelling correction: seperate --> separate.
  18
  19         Removed `:'s that had creeped into some comments.
  20
  21 *       The repl now doesn't print #<unspecified> results any longer
  22         If the user wants to see this, he can do
  23         (assert-repl-print-unspecified #t) in his startup file.
  24
  25 *       The user now gets a friendly message instead of a backtrace at
  26         error.
  27
  28         Added `before-read-hook'.
  29
  30         Load module (ice-9 emacs) if option `-e' was specified.
  31
  32         (provide): New function.
  33
  34         (error): Save stack at entry, so that Guile entrails won't show up
  35         in backtraces.
  36
  37         (backtrace): New function.
  38
  39 *       (save-stack): Can now take arbitrary number of stack narrowing
  40         specifier pairs.  The first specifier in a pair controls inner
  41         border, the second the outer border.  A number means cut that
  42         number of frames, a procedure object means cut until that object
  43         is found in operator position in a frame.
  44
  45         * debug.scm: Enable debugging evaluator and recording of positions
  46         by default.
  47
  48         * slib.scm (slib:load): Adapt to the new behavior of
  49         primitive-load: It doesn't any longer try both with and without
  50         ".scm" extension.  (We don't want to use %search-load-path here.)
  51
  52         (implementation-vicinity): New function.  slib requires it
  53
  54         (library-vicinity): Updated.
  55
  56         Load "require.scm" in the library-vicinity.
  57
  58         (install-require-vicinity, install-require-module): New functions.
  59
  60 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
  61
  62         * boot-9.scm (load-from-path): New function.
  63
  64         * boot-9.scm (try-load, basic-try-load, try-load-module,
  65         try-load): Deleted.  I don't think they're being used.
  66
  67         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
  68         so they'll get distributed.
  69
  70         Get Guile to be a little less chatty by default.  The new user
  71         should see as little clutter as possible.
  72         * r4rs.scm (%load-verbosely): Make this #f by default.
  73         * boot-9.scm (scm-repl-verbose): Make this #f by default.
  74         (scm-style-repl): Don't run 'pk' on the value passed to quit.
  75
  76         * r4rs.scm: New file.
  77         * boot-9.scm: Load r4rs.scm, first thing.
  78         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
  79         open-output-file, open-io-file, close-input-port,
  80         close-output-port, close-io-port, call-with-input-file,
  81         call-with-output-file, with-input-from-port, with-output-to-port,
  82         with-error-to-port, with-input-from-file, with-output-to-file,
  83         with-error-to-file, with-input-from-string, with-output-to-string,
  84         with-error-to-string, the-eof-object): Definitions moved to
  85         r4rs.scm.  Not all of them are R4RS, but those that are use those
  86         that are not.
  87         (load, %load-verbosely, %load-announce): Moved, along with code to
  88         set %load-hook, to r4rs.scm.
  89
  90         * test.scm: New file.
  91
  92         * boot-9.scm (integer?): Definition deleted, in favor of the one
  93         present in libguile (which used to be called int?).  I have no
  94         idea why integer? didn't just call int? to begin with.
  95
  96         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
  97         =?, >?, and >=? deleted; they're defined that way by libguile now.
  98
  99         * boot-9.scm (load): Simplified; primitive-load does most of this
 100         work now.
 101         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 102         call %load-announce.
 103
 104 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 105
 106         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 107         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 108         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 109         components.
 110         (file-is-directory?): use stat:type.
 111
 112 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 113
 114         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 115         that's now taken care of in libguile, and in a way compatible with
 116         SCSH (which this isn't).
 117
 118 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 119
 120         * boot-9.scm: Formatting tweaks.
 121
 122 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 123
 124         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 125         after-error-hook, before-backtrace-hook and after-backtrace-hook
 126         to the error handler.  E.g.: fancy emacs support could plug into
 127         these.
 128         (save-stack): New function.  The stack is now made differently
 129         depending on the stack id.  (The motivation is to make a better
 130         choice regarding what stack frames to present to the user.)
 131         (error-catching-loop): Stack handling code moved outside into
 132         save-stack.
 133
 134 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 135
 136         * Makefile.in (scm_files): add expect.scm.
 137
 138         * expect.scm: new file ported from guile-iii.
 139
 140         * boot-9.scm: remove handle-system-error, after moving the code into
 141         error-catching-loop.
 142         Don't set 'throw-handler-default property on error keys.
 143         Just interpret (almost) any throw with 4 args as an error throw.
 144         Delete some try-load stuff that was already commented out.
 145
 146         Second thoughts, keep handle-system-error but call it from
 147         error-catching-loop.
 148
 149 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 150
 151         * boot-9.scm: Doc fixes.
 152         (make-module): Rework for readability.
 153         (make-root-module, make-scm-module): USES argument to make-module
 154         should be '(), not #f.
 155
 156         * boot-9.scm (try-load): %sys-load-path has been renamed to
 157         primitive-load-path; adjust call here.
 158
 159 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 160
 161         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 162         the stack to the correct place: when it is decided to generate an
 163         error-signal.
 164
 165 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 166
 167         * boot-9.scm (error-catching-loop, signal-handler,
 168         handle-system-error): Backtracing now works for signals aswell;
 169         Backtracing mechanism can now identify the stack root created by
 170         start-stack so that the user isn't exposed to system stack frames.
 171
 172 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 173
 174         * Makefile.in: Added threads.scm.
 175
 176 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 177
 178         * debug.scm (make-enable, make-disable): Simplified.
 179
 180         * boot-9.scm: Renamed %%throw-handler-default -->
 181         throw-handler-default.
 182         ((handle-system-error key . arg-list)): Changed the way errors are
 183         reported.
 184         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 185         acro.
 186         ((error-catching-loop thunk)): Introduce a lazy-catch into
 187         error-catching-loop so that the stack can be captured.
 188
 189 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 190
 191         * mapping.scm (hash-table-mapping): Explicitly request that
 192         make-vector fill new vectors with '(); this will make it easier to
 193         port Guile Scheme code to other Schemes.
 194         * boot-9.scm (make-print-style, make-print-table): Same.
 195
 196 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 197
 198         * boot-9.scm (load): rewritten again.
 199         Append "." to the default %load-path.
 200         (feature?): new function: checks for a symbol in the features list.
 201         (module-local-variable): remove apparently useless (caddr (list m v
 202         ...))
 203         (%load-announce): minor formatting change.
 204         (file-exists?): use access? if posix is featured.
 205         (file-is-directory?): use stat if i/o-extensions is featured.
 206         (try-module-autoload module-name): use file-exists? before
 207         file-is-directory?
 208
 209 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 210
 211         * boot-9.scm: Added conditional loading of threads.scm.
 212
 213         * threads.scm: New file.  Modified from the Cygnus-r0.3
 214         distribution.
 215
 216         * boot-9.scm (error-catching-loop): Added handling of key
 217         `switch-repl'.
 218
 219         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 220
 221 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 222
 223         * boot-9.scm (make-record-type, record-constructor): Don't assume
 224         the empty list is false when parsing the argument list.
 225
 226 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 227
 228         * boot-9.scm (signal-handler): Clean up logic.
 229
 230         * boot-9.scm (load): Assume %load-path is always bound.
 231
 232 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 233
 234         * boot-9.scm (error): replace another throw with scm-error.  Throw
 235         to 'misc-error instead of 'error (no need to distinguish these.)
 236         Don't set up 'error as a key.
 237         Set up regex-error as a key, if regex is available.
 238         (signal-handler): use scm-error, not throw.
 239
 240 *       (%try-load, try-load-with-path, %load, load-with-path,
 241         basic-try-load-with-path, basic-load-with-path,
 242         try-load-module-with-path,load-module-with-path): deleted, since
 243         they seem redundant.
 244         (try-load): define using %try-load, not try-load-with-path.
 245 *       (load): rewritten.  load tries to open the file directly and
 246         with a .scm extension before searching the library directories
 247         (should "." be added to %load-path?  then load could still open
 248         directly files starting with "/").
 249         (try-module-autoload): use load, not load-with-path.
 250         (%load-indent): deleted, -2 was causing errors.
 251
 252         (%read-sharp): use port-line, not line-number.
 253
 254 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 255
 256         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 257         straightforward to provide the equivalent functionality using
 258         (catch #t ...), so there's no need for the extra complexity.  2)
 259         Outside the context of a read-eval-print loop (which Guile should
 260         not require) it's not clear we should do anything more complicated
 261         than print an error and exit; the user or REPL can establish
 262         something better if it wants.  3) In that case, it's much more
 263         robust to just do it in the C code.
 264
 265 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 266
 267         * boot-9.scm (%try-load): define using primitive-load.  Previously
 268         %try-load itself was the primitive.
 269         (load-with-path): use scm-error instead of %load-announce-lossage.
 270         Errors are thrown to 'misc-error instead of 'could-not-load.
 271         (%load-announce-lossage): deleted.
 272
 273 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 274
 275         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 276         (make-record-type type-name fields): Temporarily remove support
 277         for printing of records (not possible yet with C printer).
 278
 279 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
 280
 281         * boot-9.scm (file-exists?, file-is-directory): catch only
 282         system-error, not every kind of error.
 283         (scm-error): new procedure.
 284
 285 Thu Sep 19 16:02:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 286
 287         * boot-9.scm: Formatting tweaks.
 288
 289 Wed Sep 18 09:07:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 290
 291         * boot-9.scm (%%handle-system-error key): remove the code for
 292         SCM-style errors.  handle the case that an unexpected number
 293         of args are supplied.
 294         (%%system-errors): removed.
 295         (error): redefine using a throw with key and 4 args.
 296         ('error): associate 'error, 'error-signal keys with
 297         %%handle-system-error.
 298         (%%default-error-handler): removed.
 299         (signal-handler): throw with 4 args and use the error-signal key.
 300         Create an error message instead of using numerical codes.
 301         (%%bad-throw): call error instead of throw if key not found.
 302
 303 Tue Sep 17 04:11:28 1996  Gary Houston  <ghouston@actrix.gen.nz>
 304
 305         * boot-9.scm: initialize new error keys (see libguile/ChangeLog).
 306         (%%handle-system-error key): check subr is not #f before printing.
 307         Recognize %s (embed an argument using "display") and
 308         %S (embed an argument using "write").
 309
 310 Sun Sep 15 03:55:35 1996  Gary Houston  <ghouston@actrix.gen.nz>
 311
 312         * boot-9.scm (%%handle-system-error key): set args and rest to
 313         the empty list if they are #f.
 314         Initialize out-of-range as an error key.
 315
 316 Sat Sep 14 03:41:15 1996  Gary Houston  <ghouston@actrix.gen.nz>
 317
 318         * PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
 319
 320         * boot-9.scm: remove leading %% from references to '%%system-error.
 321         (%%handle-system-error): don't pass all the thrown arguments when
 322         aborting, just the key and subr.
 323         Remove the code to "Install default handlers for built-in errors."
 324         Remove the definition of the syserror procedure.
 325         Associate 'numerical-overflow with default handler.
 326
 327 Fri Sep 13 04:58:11 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 328
 329         * boot-9.scm: Name change: value-ref --> local-ref
 330         resolved-ref --> nested-ref  Motivation: conformance to the other
 331         dictionary operators: list-ref operates on list, vector-ref
 332         operates on vector, nested-ref operates on nested namespace,
 333         local-ref operates on the local nested namespace.
 334
 335 Sat Sep  7 06:44:47 1996  Gary Houston  <ghouston@actrix.gen.nz>
 336
 337         * boot-9.scm (%%handle-system-error): recognise errors thrown
 338         by lgh-error (fill-message etc.)
 339         (fill-message): check first whether args is null.
 340         (fill-message): bug fix and check that args is a list.
 341
 342 Thu Sep  5 11:33:41 1996  Jim Blandy  <jimb@floss.cyclic.com>
 343
 344         * boot-9.scm: %load-path is initialized in C code now.
 345         (implementation-vicinity, parse-path): Deleted, along with code to
 346         initialize %load-path.
 347
 348         * boot-9.scm (in-vicinity): If the vicinity doesn't end with a
 349         "/", use one to separate it from the file.
 350
 351 Thu Aug 29 23:05:11 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>
 352
 353         * boot-9.scm (%load-path): Add the site directory.
 354         Add the directory named after the version number.

 366         Don't use the PLUGIN system to gather information for the

 370         for these.

 410         * PLUGIN/this.configure (aux_files): Removed PLUGIN; it's a
