   2
   3         It's an "eval closure", not an "eval thunk."  A thunk is a
   4         function of no arguments.
   5         * boot-9.scm (module-type): Rename module field.
   6         (make-module, eval-in-module, make-root-module,
   7         set-current-module): Uses changed.
   8         (module-eval-closure, set-module-eval-closure!,
   9         root-module-closure): Renamed from module-eval-thunk,
  10         set-module-eval-thunk!, root-module-thunk.
  11         (set-current-module): Change uses of *top-level-lookup-thunk* to
  12         *top-level-eval-closure*.

  14 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  15
  16         * slib.scm (slib-parent-dir): Use string-length, not length.
  17         (Thanks to Bernard Urban.)

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

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

 388         for these.

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