We don't have assignments for the images smiley.el uses, but 31;; I'm not sure we need that degree of rococoness and defaults like a 32;; yellow background. Also, using PBM means we can display the images 33;; more generally. -- fx 34;; `smiley.el' was replaced by `smiley-ems.el' on 2002-01-26 (after fx' 35;; comment). 36 37;; Test smileys: 38;; smile ^:-) ^:) 39;; blink ;-) ;) 40;; forced :-] 41;; braindamaged 8-) 42;; indifferent :-| 43;; wry :-/ :-\ 44;; sad :-( 45;; frown :-{ 46;; evil >:-) 47;; cry ;-( 48;; dead X-) 49;; grin :-D 50 51;;; Code: 52 53(eval-when-compile (require 'cl)) 54(require 'nnheader) 55(require 'gnus-art) 56 57(defgroup smiley nil 58 "Turn :-)'s into real images." 59 :group 'gnus-visual) 60 61;; Maybe this should go. 62(defcustom smiley-data-directory 63 (nnheader-find-etc-directory "images/smilies") 64 "Location of the smiley faces files." 65 :type 'directory 66 :group 'smiley) 67 68;; The XEmacs version has a baroque, if not rococo, set of these. 69(defcustom smiley-regexp-alist 70 '(("\\(:-?)\\)\\W" 1 "smile") 71 ("\\(;-?)\\)\\W" 1 "blink") 72 ("\\(:-]\\)\\W" 1 "forced") 73 ("\\(8-)\\)\\W" 1 "braindamaged") 74 ("\\(:-|\\)\\W" 1 "indifferent") 75 ("\\(:-[/\\]\\)\\W" 1 "wry") 76 ("\\(:-(\\)\\W" 1 "sad") 77 ("\\(X-)\\)\\W" 1 "dead") 78 ("\\(:-{\\)\\W" 1 "frown")) 79 "*A list of regexps to map smilies to images. 80The elements are (REGEXP MATCH IMAGE), where MATCH is the submatch in 81regexp to replace with IMAGE.
