ice-9/ChangeLog

   1 Tue Jan  7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>
   2
   3         * boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
   4         that's what it is.
   5
   6         * lineio.scm (make-line-buffering-input-port): Properly test for
   7         the case of an empty buffer list.  The old code assumed that '()
   8         was false.
   9
  10 Mon Jan  6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>
  11
  12 *       * boot-9.scm (use-modules): New macro (from Marius Vollmer).
  13         (use-modules <module name> ...) Put the the modules named by
  14         <module name> ... on the use list of the current module.
  15
  16 Sun Jan  5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>
  17
  18         * boot-9.scm (error-catching-loop): Remove message saying that
  19         typing "$" will put you in the debugger.  This isn't implemented
  20         yet.
  21
  22 Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>
  23
  24         * boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
  25         been fixed, so this function is superfluous.
  26         (transform-usage-lambda): Use delq!, not delq-all!.
  27
  28 Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>
  29
  30         * boot-9.scm (resolve-module): New optional parameter that
  31         controls whether autoloading is attempted or not. Default is #t.
  32         (process-define-module): Don't autoload the defined module.
  33         (try-module-autoload): Don't autoload the directory modules.
  34
  35         * boot-9.scm (process-define-module): Ensure that the-scm-module
  36         is last in the `uses' list to allow shadowing builtin
  37         bindings. All :use-module options are added in the order they
  38         appear in the arguments but before anything already on the list
  39         (such as the-scm-module).
  40
  41 Wed Dec 11 21:06:05 1996  Gary Houston  <ghouston@actrix.gen.nz>
  42
  43         * slib.scm (slib-parent-dir): throw error if #f returned from
  44         %search-load-path.
  45
  46 Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>
  47
  48         * PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
  49         * Makefile.am, aclocal.m4: New files.
  50         * configure.in: Updated for Automake.
  51
  52 Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>
  53
  54         * boot-9.scm (macroexpand-1, macroexpand), slib.scm
  55         (slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
  56         function, use it accordingly.
  57
  58 Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>
  59
  60         It's an "eval closure", not an "eval thunk."  A thunk is a
  61         function of no arguments.
  62         * boot-9.scm (module-type): Rename module field.
  63         (make-module, eval-in-module, make-root-module,
  64         set-current-module): Uses changed.
  65         (module-eval-closure, set-module-eval-closure!,
  66         root-module-closure): Renamed from module-eval-thunk,
  67         set-module-eval-thunk!, root-module-thunk.
  68         (set-current-module): Change uses of *top-level-lookup-thunk* to
  69         *top-level-eval-closure*.
  70
  71 Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>
  72
  73         * slib.scm (slib-parent-dir): Use string-length, not length.
  74         (Thanks to Bernard Urban.)
  75
  76 Sat Nov  2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
  77
  78         * boot-9.scm: The debugging evaluator and recording of positions
  79         aren't enabled by default any longer (they are switched on in
  80         debug.scm).  But during development we want to have them also
  81         *inside* boot-9.scm.  Therefore, two lines are added at the
  82         beginning of boot-9.scm to enable these.
  83
  84         Call `provide' so that `records' are included among the
  85         `*features*'.
  86
  87         The scheme for saving the stack has been adjusted: save-stack is
  88         now commonly available for saving the stack.  Calling `save-stack'
  89         sets a flag `stack-saved?' which prevents overwriting the stack.
  90         `stack-saved?' is reset at `abort'.
  91
  92         Spelling correction: seperate --> separate.
  93
  94         Removed `:'s that had creeped into some comments.
  95
  96         The repl now doesn't print #<unspecified> results any longer
  97         If the user wants to see this, he can do
  98         (assert-repl-print-unspecified #t) in his startup file.
  99
 100         The user now gets a friendly message instead of a backtrace at
 101         error.
 102
 103         Added `before-read-hook'.
 104
 105         Load module (ice-9 emacs) if option `-e' was specified.
 106
 107         (provide): New function.
 108
 109         (error): Save stack at entry, so that Guile entrails won't show up
 110         in backtraces.
 111
 112         (backtrace): New function.
 113
 114         (save-stack): Can now take arbitrary number of stack narrowing
 115         specifier pairs.  The first specifier in a pair controls inner
 116         border, the second the outer border.  A number means cut that
 117         number of frames, a procedure object means cut until that object
 118         is found in operator position in a frame.
 119
 120         * debug.scm: Enable debugging evaluator and recording of positions
 121         by default.
 122
 123         * slib.scm (slib:load): Adapt to the new behavior of
 124         primitive-load: It doesn't any longer try both with and without
 125         ".scm" extension.  (We don't want to use %search-load-path here.)
 126
 127         (implementation-vicinity): New function.  slib requires it
 128
 129         (library-vicinity): Updated.
 130
 131         Load "require.scm" in the library-vicinity.
 132
 133         (install-require-vicinity, install-require-module): New functions.
 134
 135 Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>
 136
 137         * boot-9.scm (load-from-path): New function.
 138
 139         * boot-9.scm (try-load, basic-try-load, try-load-module,
 140         try-load): Deleted.  I don't think they're being used.
 141
 142         * Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
 143         so they'll get distributed.
 144
 145         Get Guile to be a little less chatty by default.  The new user
 146         should see as little clutter as possible.
 147         * r4rs.scm (%load-verbosely): Make this #f by default.
 148         * boot-9.scm (scm-repl-verbose): Make this #f by default.
 149         (scm-style-repl): Don't run 'pk' on the value passed to quit.
 150
 151         * r4rs.scm: New file.
 152         * boot-9.scm: Load r4rs.scm, first thing.
 153         (OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
 154         open-output-file, open-io-file, close-input-port,
 155         close-output-port, close-io-port, call-with-input-file,
 156         call-with-output-file, with-input-from-port, with-output-to-port,
 157         with-error-to-port, with-input-from-file, with-output-to-file,
 158         with-error-to-file, with-input-from-string, with-output-to-string,
 159         with-error-to-string, the-eof-object): Definitions moved to
 160         r4rs.scm.  Not all of them are R4RS, but those that are use those
 161         that are not.
 162         (load, %load-verbosely, %load-announce): Moved, along with code to
 163         set %load-hook, to r4rs.scm.
 164
 165         * test.scm: New file.
 166
 167         * boot-9.scm (integer?): Definition deleted, in favor of the one
 168         present in libguile (which used to be called int?).  I have no
 169         idea why integer? didn't just call int? to begin with.
 170
 171         * boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
 172         =?, >?, and >=? deleted; they're defined that way by libguile now.
 173
 174         * boot-9.scm (load): Simplified; primitive-load does most of this
 175         work now.
 176         (%load-announce-win): Removed; no longer used.  Set %load-hook to
 177         call %load-announce.
 178
 179 Sun Oct 27 07:47:03 1996  Gary Houston  <ghouston@actrix.gen.nz>
 180
 181         * boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
 182         stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
 183         stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
 184         components.
 185         (file-is-directory?): use stat:type.
 186
 187 Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>
 188
 189         * boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
 190         that's now taken care of in libguile, and in a way compatible with
 191         SCSH (which this isn't).
 192
 193 Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 194
 195         * boot-9.scm: Formatting tweaks.
 196
 197 Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
 198
 199         * boot-9.scm (handle-system-error): Added hooks before-error-hook,
 200         after-error-hook, before-backtrace-hook and after-backtrace-hook
 201         to the error handler.  E.g.: fancy emacs support could plug into
 202         these.
 203         (save-stack): New function.  The stack is now made differently
 204         depending on the stack id.  (The motivation is to make a better
 205         choice regarding what stack frames to present to the user.)
 206         (error-catching-loop): Stack handling code moved outside into
 207         save-stack.
 208
 209 Thu Oct 17 20:33:08 1996  Gary Houston  <ghouston@actrix.gen.nz>
 210
 211         * Makefile.in (scm_files): add expect.scm.
 212
 213         * expect.scm: new file ported from guile-iii.
 214
 215         * boot-9.scm: remove handle-system-error, after moving the code into
 216         error-catching-loop.
 217         Don't set 'throw-handler-default property on error keys.
 218         Just interpret (almost) any throw with 4 args as an error throw.
 219         Delete some try-load stuff that was already commented out.
 220
 221         Second thoughts, keep handle-system-error but call it from
 222         error-catching-loop.
 223
 224 Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>
 225
 226         * boot-9.scm: Doc fixes.
 227         (make-module): Rework for readability.
 228         (make-root-module, make-scm-module): USES argument to make-module
 229         should be '(), not #f.
 230
 231         * boot-9.scm (try-load): %sys-load-path has been renamed to
 232         primitive-load-path; adjust call here.
 233
 234 Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 235
 236         * boot-9.scm (signal-handler): Bugfix: Moved the recording of
 237         the stack to the correct place: when it is decided to generate an
 238         error-signal.
 239
 240 Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 241
 242         * boot-9.scm (error-catching-loop, signal-handler,
 243         handle-system-error): Backtracing now works for signals aswell;
 244         Backtracing mechanism can now identify the stack root created by
 245         start-stack so that the user isn't exposed to system stack frames.
 246
 247 Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 248
 249         * Makefile.in: Added threads.scm.
 250
 251 Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>
 252
 253         * debug.scm (make-enable, make-disable): Simplified.
 254
 255         * boot-9.scm: Renamed %%throw-handler-default -->
 256         throw-handler-default.
 257         ((handle-system-error key . arg-list)): Changed the way errors are
 258         reported.
 259         ((scm-style-repl)): Wrap up the call to eval in a start-stack
 260         acro.
 261         ((error-catching-loop thunk)): Introduce a lazy-catch into
 262         error-catching-loop so that the stack can be captured.
 263
 264 Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 265
 266         * mapping.scm (hash-table-mapping): Explicitly request that
 267         make-vector fill new vectors with '(); this will make it easier to
 268         port Guile Scheme code to other Schemes.
 269         * boot-9.scm (make-print-style, make-print-table): Same.
 270
 271 Sun Oct  6 03:54:59 1996  Gary Houston  <ghouston@actrix.gen.nz>
 272
 273         * boot-9.scm (load): rewritten again.
 274         Append "." to the default %load-path.
 275         (feature?): new function: checks for a symbol in the features list.
 276         (module-local-variable): remove apparently useless (caddr (list m v
 277         ...))
 278         (%load-announce): minor formatting change.
 279         (file-exists?): use access? if posix is featured.
 280         (file-is-directory?): use stat if i/o-extensions is featured.
 281         (try-module-autoload module-name): use file-exists? before
 282         file-is-directory?
 283
 284 Sat Oct  5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>
 285
 286         * boot-9.scm: Added conditional loading of threads.scm.
 287
 288         * threads.scm: New file.  Modified from the Cygnus-r0.3
 289         distribution.
 290
 291         * boot-9.scm (error-catching-loop): Added handling of key
 292         `switch-repl'.
 293
 294         * boot-9.scm: Name change %%bad-throw --> bad-throw.
 295
 296 Wed Oct  2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 297
 298         * boot-9.scm (make-record-type, record-constructor): Don't assume
 299         the empty list is false when parsing the argument list.
 300
 301 Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 302
 303         * boot-9.scm (signal-handler): Clean up logic.
 304
 305         * boot-9.scm (load): Assume %load-path is always bound.
 306
 307 Sat Sep 28 00:15:37 1996  Gary Houston  <ghouston@actrix.gen.nz>
 308
 309         * boot-9.scm (error): replace another throw with scm-error.  Throw
 310         to 'misc-error instead of 'error (no need to distinguish these.)
 311         Don't set up 'error as a key.
 312         Set up regex-error as a key, if regex is available.
 313         (signal-handler): use scm-error, not throw.
 314
 315         (%try-load, try-load-with-path, %load, load-with-path,
 316         basic-try-load-with-path, basic-load-with-path,
 317         try-load-module-with-path,load-module-with-path): deleted, since
 318         they seem redundant.
 319         (try-load): define using %try-load, not try-load-with-path.
 320         (load): rewritten.  load tries to open the file directly and
 321         with a .scm extension before searching the library directories
 322         (should "." be added to %load-path?  then load could still open
 323         directly files starting with "/").
 324         (try-module-autoload): use load, not load-with-path.
 325         (%load-indent): deleted, -2 was causing errors.
 326
 327         (%read-sharp): use port-line, not line-number.
 328
 329 Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>
 330
 331         * boot-9.scm (%%bad-throw): Delete definition. 1) It's very
 332         straightforward to provide the equivalent functionality using
 333         (catch #t ...), so there's no need for the extra complexity.  2)
 334         Outside the context of a read-eval-print loop (which Guile should
 335         not require) it's not clear we should do anything more complicated
 336         than print an error and exit; the user or REPL can establish
 337         something better if it wants.  3) In that case, it's much more
 338         robust to just do it in the C code.
 339
 340 Tue Sep 24 06:53:04 1996  Gary Houston  <ghouston@actrix.gen.nz>
 341
 342         * boot-9.scm (%try-load): define using primitive-load.  Previously
 343         %try-load itself was the primitive.
 344         (load-with-path): use scm-error instead of %load-announce-lossage.
 345         Errors are thrown to 'misc-error instead of 'could-not-load.
 346         (%load-announce-lossage): deleted.
 347
 348 Mon Sep 23 00:16:31 1996  Mikael Djurfeldt  <mdj@kenneth>
 349
 350         * boot-9.scm (warn, scm-style-repl): Use C printer instead of `print'.
 351         (make-record-type type-name fields): Temporarily remove support
 352         for printing of records (not possible yet with C printer).
 353
 354 Fri Sep 20 00:24:27 1996  Gary Houston  <ghouston@actrix.gen.nz>
