  81         account new libguile support for Elisp nil value.
  82
  83 2002-02-06  Neil Jerram  <neil@ossau.uklinux.net>
  84
  85         * example.el (time): New macro, for performance measurement.
  86         Accompanying comment compares results for Guile and Emacs.
  87
  88         * transform.scm (scheme): New macro.
  89         (transformer): New implementation of `scheme' escape that doesn't
  90         rely on (lang elisp base) importing Guile bindings.
  91
  92         * base.scm: No longer import anything from (guile).
  93         (load-emacs): Add scheme form to ensure that keywords
  94         read option is set correctly.
  95
  96         * primitives/syntax.scm (defmacro, let, let*): Unquote uses of
  97         `@bind' in transformed code.

 110
 111         * primitives/syntax.scm (parse-formals, transform-lambda,
 112         interactive-spec, set-not-subr!, transform-lambda/interactive):
 113         Move into internals/lambda.scm so that these can also be used
 114         by...
 115
 116         * internals/fset.scm (elisp-apply): Use `eval' and
 117         `transform-lambda/interactive' to turn a quoted lambda expression
 118         into a Scheme procedure.
 119
 120         * transform.scm (m-quasiquote): Don't quote `quasiquote' in
 121         transformed code.

 127
 128         * internals/lambda.scm (lang): New file.
 129
 130 2002-02-01  Neil Jerram  <neil@ossau.uklinux.net>
 131
 132         * transform.scm (transformer), primitives/syntax.scm (let*):
 133         Unquote uses of `begin' in transformed code.
 134
 135 2002-01-29  Neil Jerram  <neil@ossau.uklinux.net>
 136
 137         * transform.scm (transform-1, transform-2, transform-3,
 138         transform-list): Removed (unused).
 139
 140         * transform.scm, primitives/syntax.scm: Add commas everywhere
 141         before use of (guile) primitives in generated code, so that (lang
 142         elisp base) doesn't have to import bindings from (guile).
 143
 144         * base.scm: Move use-modules expressions inside the define-module,
 145         and add #:pure so that we don't import bindings from (guile).
 146
 147 2002-01-25  Neil Jerram  <neil@ossau.uklinux.net>
 148
 149         * transform.scm (transform-application): Preserve source
 150         properties of original elisp expression by using cons-source.
 151
 152         * transform.scm: Don't handle special forms specially in the
 153         translator.  Instead, define them as macros in ...
 154
 155         * primitives/syntax.scm: New file; special form definitions.
 156
 157         * primitives/fns.scm (run-hooks): Rewritten correctly.
 158
 159         * primitives/symprop.scm (symbol-value): Use `value'.
 160
 161         * internals/set.scm (value): New function.
 162
 163         * primitives/fns.scm: Use (lang elisp internals null), as null is
 164         no longer a primitive.  Change generated #f values to %nil.
 165
 166         * internals/null.scm (null): Handle nil symbol.
 167
 168         * primitives/lists.scm (memq, member, assq, assoc): Handle all
 169         possible nil values.
 170

 173
 174         * base.scm: Remove setting of 'language read-option.
 175
 176 2001-11-03  Neil Jerram  <neil@ossau.uklinux.net>
 177
 178         * README (Resources): Fill in missing URLs.
 179
 180 2001-11-02  Neil Jerram  <neil@ossau.uklinux.net>
 181
 182         * Makefile.am (elisp_sources): Added base.scm, example.el,
 183         interface.scm; removed emacs.scm.
 184
 185         * README: Updated accordingly.
 186
 187         * internals/load.scm (load): Avoid using `load-path' if the
 188         supplied file name begins with a slash.
 189
 190         * internals/fset.scm: Support export of defuns, defmacros and
 191         defvars to a module specified by the fluid `elisp-export-module'.
 192         This allows us to automate the importing of Elisp definitions into
 193         Scheme.
 194
 195         * example.el: New file: example code for `load-elisp-file'.
 196
 197         * interface.scm: New file - mechanisms to exchange definitions
 198         between Scheme and Elisp.
 199
 200         Following changes try to make the Elisp evaluation module less
 201         Emacs-dependent; in other words, so that it isn't necessary to try
 202         to load the whole Emacs environment before evaluating basic
 203         non-Emacs-specific Elisp code.
 204
 205         * variables.scm, internals/evaluation.scm: Changed (lang elisp
 206         emacs) to (lang elisp base).
 207
 208         * emacs.scm (lang): Removed.
 209
 210         * base.scm (lang): New file (non-emacs-specific replacement for
 211         emacs.scm).
 212
 213 2001-10-28  Neil Jerram  <neil@ossau.uklinux.net>
 214
 215         * primitives/symprop.scm (symbol-name): New primitive.
 216
 217         * primitives/strings.scm (stringp): New primitive.
 218
 219         * primitives/pure.scm (purify-flag): New variable.
 220
 221         * primitives/numbers.scm (numberp): New primitive.
 222
 223         * internals/fset.scm (fset): Set procedure and macro name
 224         properties usefully to match Elisp symbol names.  Also bind Elisp
 225         function definition variables to similarly named symbols in the
 226         (lang elisp variables) module.
 227
 228         * transform.scm (transformer, m-unwind-protect): Added support for
 229         `unwind-protect'.
 230         (m-quasiquote): Use 'quasiquote rather than 'quote.
 231         (transform-lambda, m-defmacro): When no rest arguments, set the
 232         rest parameter to '() rather than #f.  It shouldn't make any
 233         difference, but it feels more right.
 234
 235         * README: Enlarged description of current status.
 236
 237         * Makefile.am (elisp_sources): Added variables.scm.
 238
 239         * variables.scm: New file.
 240
 241 2001-10-26  Neil Jerram  <neil@ossau.uklinux.net>
 242
 243         * buffers.scm, calling.scm: Removed.  These should have
 244         disappeared during the reorganization described below, but I
 245         missed them by mistake.
 246
 247         * primitives/symprop.scm (set, boundp, symbol-value): Changed to
 248         use (module-xx the-elisp-module ...) rather than (local-xx ...).
 249         (symbolp): Accept either symbols or keywords.
 250         (set-default, default-boundp, default-value,
 251         local-variable-if-set-p): New.
 252
 253         * primitives/match.scm (string-match, match-data): Store last
 254         match data in Emacs rather than Guile form, to simplify
 255         implementation of ...
 256         (set-match-data, store-match-data): New.
 257
 258         * primitives/load.scm (autoload, current-load-list): New.  (But
 259         autoload is just stubbed, not properly implemented.)
 260
 261         * primitives/lists.scm (nth, listp, consp, nconc): New.
 262
 263         * primitives/fns.scm (byte-code-function-p, run-hooks): New.
 264
 265         * transform.scm (transform-application, transformer-macro): New
 266         scheme for transforming procedure arguments while leaving macro
 267         args untransformed.  (See also associated change in libguile.)
 268         (m-defconst): Simplified, now uses m-setq.
 269
 270         * Makefile.am: Changed so that it only deals with files directly
 271         in this directory; otherwise files don't install cleanly.
 272
 273         * internals/Makefile.am, primitives/Makefile.am,
 274         internals/.cvsignore, primitives/.cvsignore: New files.
 275
 276 2001-10-26  Neil Jerram  <neil@ossau.uklinux.net>
 277
 278         * transform.scm (transformer): New handling for (1) quasiquoting
 279         syntax like "(` ...)" as well as the more normal "` ..."; (2)
 280         `function'; (3) interactive specification in lambda body.
 281         Simplied handling for `setq'.
 282         (transform-inside-qq): Fixed to handle improper as well as proper
 283         lists.
 284         (transform-lambda/interactive): New; wraps transform-lambda to
 285         handle setting of various procedure properties.
 286         (transform-lambda, m-defmacro): Changed `args' and `num-args' to
 287         `%--args' and `%--num-args' in the hope of avoiding lexical
 288         vs. dynamic name clashes.
 289         (m-and): Use #f instead of '() where a condition fails.
 290
 291         Plus big hierarchy reorganization, in which most of the previous
 292         occupants of lang/elisp moved to lang/elisp/primitives, with some
 293         internal processing being split out into lang/elisp/internals.
 294         The upshot looks like this:
 295
 296         * internals/trace.scm, internals/set.scm, internals/load.scm,
 297         internals/fset.scm, internals/signal.scm, internals/time.scm,
 298         internals/format.scm, internals/null.scm,
 299         internals/evaluation.scm, primitives/buffers.scm,

 302         primitives/lists.scm, primitives/load.scm, primitives/match.scm,
 303         primitives/numbers.scm, primitives/pure.scm, primitives/read.scm,
 304         primitives/signal.scm, primitives/strings.scm,
 305         primitives/symprop.scm, primitives/system.scm, primitives/fns.scm:
 306         New files.
 307
 308         * features.scm, format.scm, fset.scm, guile.scm, keymaps.scm,
 309         lists.scm, load.scm, match.scm, numbers.scm, pure.scm, read.scm,
 310         signal.scm, strings.scm, symprop.scm, system.scm, time.scm,
 311         trace.scm: Removed files.
 312
 313 2001-10-23  Neil Jerram  <neil@ossau.uklinux.net>
 314
 315         * match.scm (string-match): New implementation using new
 316         `make-emacs-regexp' primitive; old workaround implementation
 317         renamed to `string-match-workaround'.
 318
 319 2001-10-21  Neil Jerram  <neil@ossau.uklinux.net>
 320
 321         * transform.scm (m-defun, m-defmacro, m-let, m-defvar,
 322         m-defconst): Use more selective tracing mechanism (provided by new
 323         file trace.scm).
 324
 325         * symprop.scm (get, boundp), transform.scm (transform-lambda,
 326         m-defmacro): Remove unnecessary uses of nil-ify and t-ify.
 327
 328         * match.scm (string-match): Workaround Guile/libc regex
 329         parenthesis bug.
 330
 331         * emacs.scm: Move elisp primitive definitions into more specific
 332         files, so that emacs.scm contains only overall code.
 333
 334         * Makefile.am: Added new files.
 335
 336         * numbers.scm, trace.scm, time.scm, pure.scm, system.scm,
 337         read.scm, calling.scm, guile.scm: New files.
 338
 339 2001-10-20  Neil Jerram  <neil@ossau.uklinux.net>
 340
 341         * Makefile.am (elisp_sources): Added match.scm and strings.scm.

 344
 345 2001-10-19  Neil Jerram  <neil@ossau.uklinux.net>
 346
 347         * transform.scm: Replace uses of `nil' by `#f' or `'()'.
 348
 349         * Makefile.am (elisp_sources): Added lists.scm.
 350
 351         * load.scm (the-elisp-module): Corrected (lang elisp emacs) module
 352         name.
 353
 354         * lists.scm (lang): New file containing list-related primitives.

 357
 358 2001-10-19  Neil Jerram  <neil@ossau.uklinux.net>
 359
 360         Initial implementation of an Emacs Lisp translator, based on
 361         transformer code originally written by Mikael Djurfeldt.
 362
