2001-11-02 Neil Jerram <neil@ossau.uklinux.net>
* Makefile.am (elisp_sources): Added base.scm, example.el,
interface.scm; removed emacs.scm.
* README: Updated accordingly.
* internals/load.scm (load): Avoid using `load-path' if the
supplied file name begins with a slash.
* internals/fset.scm: Support export of defuns, defmacros and
defvars to a module specified by the fluid `elisp-export-module'.
This allows us to automate the importing of Elisp definitions into
Scheme.
* example.el: New file: example code for `load-elisp-file'.
* interface.scm: New file - mechanisms to exchange definitions
between Scheme and Elisp.
Following changes try to make the Elisp evaluation module less
Emacs-dependent; in other words, so that it isn't necessary to try
to load the whole Emacs environment before evaluating basic
non-Emacs-specific Elisp code.
* variables.scm, internals/evaluation.scm: Changed (lang elisp
emacs) to (lang elisp base).
* emacs.scm (lang): Removed.
* base.scm (lang): New file (non-emacs-specific replacement for
emacs.scm).
2001-10-28 Neil Jerram <neil@ossau.uklinux.net>
* primitives/symprop.scm (symbol-name): New primitive.
* primitives/strings.scm (stringp): New primitive.
* primitives/pure.scm (purify-flag): New variable.
* primitives/numbers.scm (numberp): New primitive.
* internals/fset.scm (fset): Set procedure and macro name
properties usefully to match Elisp symbol names. Also bind Elisp
function definition variables to similarly named symbols in the
(lang elisp variables) module.
* transform.scm (transformer, m-unwind-protect): Added support for
`unwind-protect'.
(m-quasiquote): Use 'quasiquote rather than 'quote.
(transform-lambda, m-defmacro): When no rest arguments, set the
rest parameter to '() rather than #f. It shouldn't make any
difference, but it feels more right.
* README: Enlarged description of current status.
* Makefile.am (elisp_sources): Added variables.scm.
* variables.scm: New file.
2001-10-26 Neil Jerram <neil@ossau.uklinux.net>
* buffers.scm, calling.scm: Removed. These should have
disappeared during the reorganization described below, but I
missed them by mistake.
* primitives/symprop.scm (set, boundp, symbol-value): Changed to
use (module-xx the-elisp-module ...) rather than (local-xx ...).
(symbolp): Accept either symbols or keywords.
(set-default, default-boundp, default-value,
local-variable-if-set-p): New.
* primitives/match.scm (string-match, match-data): Store last
match data in Emacs rather than Guile form, to simplify
implementation of ...
(set-match-data, store-match-data): New.
* primitives/load.scm (autoload, current-load-list): New. (But
autoload is just stubbed, not properly implemented.)
* primitives/lists.scm (nth, listp, consp, nconc): New.
* primitives/fns.scm (byte-code-function-p, run-hooks): New.
* transform.scm (transform-application, transformer-macro): New
scheme for transforming procedure arguments while leaving macro
args untransformed. (See also associated change in libguile.)
(m-defconst): Simplified, now uses m-setq.
* Makefile.am: Changed so that it only deals with files directly
in this directory; otherwise files don't install cleanly.
* internals/Makefile.am, primitives/Makefile.am,
internals/.cvsignore, primitives/.cvsignore: New files.
2001-10-26 Neil Jerram <neil@ossau.uklinux.net>
* transform.scm (transformer): New handling for (1) quasiquoting
syntax like "(` ...)" as well as the more normal "` ..."; (2)
`function'; (3) interactive specification in lambda body.
Simplied handling for `setq'.
(transform-inside-qq): Fixed to handle improper as well as proper
lists.
(transform-lambda/interactive): New; wraps transform-lambda to
handle setting of various procedure properties.
(transform-lambda, m-defmacro): Changed `args' and `num-args' to
`%--args' and `%--num-args' in the hope of avoiding lexical
vs. dynamic name clashes.
(m-and): Use #f instead of '() where a condition fails.
Plus big hierarchy reorganization, in which most of the previous
occupants of lang/elisp moved to lang/elisp/primitives, with some
internal processing being split out into lang/elisp/internals.
The upshot looks like this:
* internals/trace.scm, internals/set.scm, internals/load.scm,
internals/fset.scm, internals/signal.scm, internals/time.scm,
internals/format.scm, internals/null.scm,
internals/evaluation.scm, primitives/buffers.scm,
primitives/features.scm, primitives/format.scm,
primitives/time.scm, primitives/guile.scm, primitives/keymaps.scm,
primitives/lists.scm, primitives/load.scm, primitives/match.scm,
primitives/numbers.scm, primitives/pure.scm, primitives/read.scm,
primitives/signal.scm, primitives/strings.scm,
primitives/symprop.scm, primitives/system.scm, primitives/fns.scm:
New files.
* features.scm, format.scm, fset.scm, guile.scm, keymaps.scm,
lists.scm, load.scm, match.scm, numbers.scm, pure.scm, read.scm,
signal.scm, strings.scm, symprop.scm, system.scm, time.scm,
trace.scm: Removed files.
2001-10-23 Neil Jerram <neil@ossau.uklinux.net>
* match.scm (string-match): New implementation using new
`make-emacs-regexp' primitive; old workaround implementation
renamed to `string-match-workaround'.
2001-10-21 Neil Jerram <neil@ossau.uklinux.net>
* transform.scm (m-defun, m-defmacro, m-let, m-defvar,
m-defconst): Use more selective tracing mechanism (provided by new
file trace.scm).
* symprop.scm (get, boundp), transform.scm (transform-lambda,
m-defmacro): Remove unnecessary uses of nil-ify and t-ify.
* match.scm (string-match): Workaround Guile/libc regex
parenthesis bug.
* emacs.scm: Move elisp primitive definitions into more specific
files, so that emacs.scm contains only overall code.
* Makefile.am: Added new files.
* numbers.scm, trace.scm, time.scm, pure.scm, system.scm,
read.scm, calling.scm, guile.scm: New files.
2001-10-20 Neil Jerram <neil@ossau.uklinux.net>
* Makefile.am (elisp_sources): Added match.scm and strings.scm.
* match.scm, strings.scm: New files.
2001-10-19 Neil Jerram <neil@ossau.uklinux.net>
* transform.scm: Replace uses of `nil' by `#f' or `'()'.
* Makefile.am (elisp_sources): Added lists.scm.
* load.scm (the-elisp-module): Corrected (lang elisp emacs) module
name.
* lists.scm (lang): New file containing list-related primitives.
* emacs.scm: Corrected module name.
2001-10-19 Neil Jerram <neil@ossau.uklinux.net>
Initial implementation of an Emacs Lisp translator, based on
transformer code originally written by Mikael Djurfeldt.
* Makefile.am, .cvsignore: New.
* ChangeLog, README, buffers.scm, emacs.scm, features.scm,
format.scm, fset.scm, keymaps.scm, load.scm, signal.scm,
symprop.scm, transform.scm: New files.
