ice-9/ChangeLog

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