view lisp/site-load.el @ 5914:bd4d2c8ef9cc
Use the existing C-level line number cache within #'line-number.
src/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* buffer.c:
* buffer.c (Fline_number): New C implementation, using the line
number cache of line-number.c, with a new optional BUFFER
argument.
* buffer.c (syms_of_buffer):
Make it available to Lisp.
* line-number.c (buffer_line_number):
New argument, RESPECT-NARROWING, describing whether to count from
the beginning of the visible region or from the beginning of the
buffer.
* line-number.h:
* line-number.h (buffer_line_number): Update its declaration.
* redisplay.c (window_line_number): Call it with the new argument.
lisp/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* simple.el:
* simple.el (line-number): Moved to buffer.c; we have an existing
line number cache in C, it's a shame not to have it available.

If not, see <http://www.gnu.org/licenses/>. ;;; Commentary: ;; This is a prototype site-load.el file. ;; The site-load.el mechanism is provided so XEmacs installers can easily ;; dump lisp packages with XEmacs that do not get dumped standardly. ;; The file `site-packages' if it exists should look something like: ;; (setq site-load-packages '( ;; "../lisp/modes/cc-mode.elc" ;; "../lisp/utils/redo.elc" ;; "../lisp/packages/scroll-in-place.elc" ;; ) ;; ) ;; The first line and the last line must be exact. Each of the packages ;; listed must be double quoted, have either an absolute path, or a relative ;; to the build src directory path *and* be bytecompiled prior to the attempt ;; to dump. They also must explicitly have the .elc extension. ;; Because this is a trial implementation and the file is shared with ;; make-docfiles, syntax is strict and unforgiving. So sue me. It ;; is still better than the way it used to be. ;; Also note that site-packages belongs in the top level directory not the ;; lisp directory for use with --srcdir configurations. ;;; Code: (defvar site-load-package-file "../site-packages" "File name containing the list of extra packages to dump with XEmacs.") (defvar site-load-packages nil "A list of .elc files that should be dumped with XEmacs. This variable should be set by `site-load-package-file'.") ;; Load site specific packages for dumping with the XEmacs binary. (when (file-exists-p site-load-package-file) (let ((file)) (load site-load-package-file t t t) ;; The `pureload' macro is provided as a clue that a package is ;; being loaded in preparation of being dumped into XEmacs. (defmacro pureload (file) (list 'prog1 (list 'load file) '(garbage-collect))) (message "Loading site-wide packages for dumping...") (while site-load-packages (setq file (car site-load-packages)) (pureload file) (setq site-load-packages (cdr site-load-packages))) (message "Loading site-wide packages for dumping...done") (fmakunbound 'pureload))) ;; This file is intended for end user additions. ;; Put other initialization here, like setting of language-environment, etc. ;; Perhaps this should really be in the site-init.el. ;;; site-load.el ends here
