annotate lisp/font.el @ 4607:517f6887fbc0
Remove duplicate functions, chiefly #'delete-duplicates reimplementations.
lisp/ChangeLog addition:
2009-02-08 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (delete-duplicates):
Add a new compiler macro, inlining this function if it's called
with a literal #'eq or #'equal test arguments and no other
keywords.
* font-lock.el (font-lock-unique):
Remove this function.
* font-lock.el (font-lock-prepend-text-property):
(font-lock-append-text-property):
Use #'delete-duplicates instead of #'font-lock-unique.
* font.el (font-unique):
Remove this function.
* font.el (font-combine-fonts-internal):
(x-font-families-for-device):
(xft-font-families-for-device):
(ns-font-families-for-device):
Use #'delete-duplicates instead of #'font-unique.
* fontconfig.el (fc-delete-duplicates):
* fontconfig.el (fc-filter):
Remove these functions.
* fontconfig.el (fc-find-available-font-families):
Replace #'fc-delete-duplicates with #'delete-duplicates,
#'fc-filter with #'delete-if-not.
* format.el (format-make-relatively-unique):
Document that this is equivalent to #'nset-exclusive-or with a
test of #'equal.

29 | |
30 ;;; Commentary: | |
428 | 31 |
3094 | 32 ;; This file is totally bogus in the context of Emacs. Much of what it does |
33 ;; is really in the provice of faces (for example all the style parameters), | |
34 ;; and that's the way it is in GNU Emacs. | |
35 ;; | |
36 ;; What is needed for fonts at the Lisp level is a consistent way to access | |
37 ;; face properties that are actually associated with fonts for some rendering | |
38 ;; engine, in other words, the kinds of facilities provided by fontconfig | |
39 ;; patterns. We just need to provide an interface to looking up, storing, | |
40 ;; and manipulating font specifications with certain properties. There will | |
41 ;; be some engine-specific stuff, like the bogosity of X11's character set | |
42 ;; registries. | |
