annotate lisp/site-load.el @ 5651:ae2fdb1fd9e0
Improve for-effect handling in a few places, lisp/
lisp/ChangeLog addition:
2012-05-01 Aidan Kehoe <kehoea@parhasard.net>
* byte-optimize.el (byte-optimize-form-code-walker):
* byte-optimize.el (byte-optimize-or):
Improve handling of for-effect here; we don't need to worry about
discarding multiple values when for-effect is non-nil, this
applies to both #'prog1 and #'or.
* bytecomp.el (progn):
* bytecomp.el (byte-compile-file-form-progn): New.
Put back this function, since it's for-effect there's no need to
worry about passing back multiple values.
* cl-macs.el (cl-pop2):
* cl-macs.el (cl-do-pop):
* cl-macs.el (remf):
* cl.el (pop):
Expand to (prog1 (car-safe PLACE) (setq PLACE (cdr PLACE))) in all
these macros, since that optimizes better (especially for-effect
handling) when byte-compile-delete-errors is nil.

| 428 | 22 ;;; Commentary: |
| 23 | |
| 24 ;; This is a prototype site-load.el file. | |
| 25 ;; The site-load.el mechanism is provided so XEmacs installers can easily | |
| 26 ;; dump lisp packages with XEmacs that do not get dumped standardly. | |
| 27 | |
| 28 ;; The file `site-packages' if it exists should look something like: | |
| 29 ;; (setq site-load-packages '( | |
| 30 ;; "../lisp/modes/cc-mode.elc" | |
| 31 ;; "../lisp/utils/redo.elc" | |
| 32 ;; "../lisp/packages/scroll-in-place.elc" | |
| 33 ;; ) | |
| 34 ;; ) | |
| 35 | |
| 36 ;; The first line and the last line must be exact. Each of the packages | |
| 37 ;; listed must be double quoted, have either an absolute path, or a relative | |
| 38 ;; to the build src directory path *and* be bytecompiled prior to the attempt | |
| 39 ;; to dump. They also must explicitly have the .elc extension. | |
| 40 | |
| 41 ;; Because this is a trial implementation and the file is shared with | |
| 42 ;; make-docfiles, syntax is strict and unforgiving. So sue me. It | |
| 43 ;; is still better than the way it used to be. | |
| 44 | |
| 45 ;; Also note that site-packages belongs in the top level directory not the | |
| 46 ;; lisp directory for use with --srcdir configurations. | |
| 47 | |
| 48 ;;; Code: | |
| 49 (defvar site-load-package-file "../site-packages" | |
| 50 "File name containing the list of extra packages to dump with XEmacs.") | |
| 51 (defvar site-load-packages nil | |
| 52 "A list of .elc files that should be dumped with XEmacs. | |
| 53 This variable should be set by `site-load-package-file'.") | |
| 54 | |
| 55 ;; Load site specific packages for dumping with the XEmacs binary. | |
| 56 (when (file-exists-p site-load-package-file) | |
| 57 (let ((file)) | |
| 58 (load site-load-package-file t t t) | |
| 59 ;; The `pureload' macro is provided as a clue that a package is | |
| 60 ;; being loaded in preparation of being dumped into XEmacs. | |
| 61 (defmacro pureload (file) | |
| 62 (list 'prog1 (list 'load file) '(garbage-collect))) | |
| 63 (message "Loading site-wide packages for dumping...") | |
| 64 (while site-load-packages | |
| 65 (setq file (car site-load-packages)) | |
| 66 (pureload file) | |
| 67 (setq site-load-packages (cdr site-load-packages))) | |
| 68 (message "Loading site-wide packages for dumping...done") | |
| 69 (fmakunbound 'pureload))) | |
| 70 | |
| 71 ;; This file is intended for end user additions. | |
| 72 ;; Put other initialization here, like setting of language-environment, etc. | |
| 73 ;; Perhaps this should really be in the site-init.el. | |
| 74 | |
