25
26 ;; A smart editing mode for m4 macro definitions. It seems to have most of the
27 ;; syntax right (sexp motion commands work, but function motion commands don't).
28 ;; It also sets the font-lock syntax stuff for colorization

33 ;; History:
34
35 ;; Date Version Who Action
36 ;; -------- ------- --- ----
37 ;; 09/13/96 1.0 DC Created
38 ;; 09/26/96 1.1 DC added syntax table stuff so now matches `'s
39 ;; now can use C-c C-b to m4 on buffer,C-c C-r for region
40 ;; added m4-comment-region (C-c C-c)
41 ;; 09/27/96 1.2 DC Redid header comment
42 ;; 1.3 DC more cosmetic fixes
43 ;; 1.4 DC removed m4-comment-region, using comment-region instead
44 ;; 10/03/96 DC added provide line
45 ;; 10/24/96 1.5 DC fixed keyword regexp
46 ;; 10/29/96 1.6 DC added m4_keywords for --prefix-builtins
47 ;; fixed syntax table so _define_ isn't keywordified
48 ;; 10/29/96 1.8 DC fixed a problem where comments go fontified incorrectly
49 ;; if they had quotes in them
50 ;; To Do's:
51
52 ;; * want to make m4-m4-(buffer|region) look sorta like M-x compile look&feel ?
53 ;; * sexp motion commands don't seem to work right
54
55 ;; to autoload m4 lisp code:
56 ;; (autoload 'm4-mode "m4-mode" nil t)
57 ;;
58 ;; or can use (load "m4-mode") or (require 'm4-mode) to just load it
59 ;;
60 ;; to try to "auto-detect" m4 files:
61 ;; (setq auto-mode-alist
62 ;; (cons '(".*\\.m4$" . m4-mode)
63 ;; auto-mode-alist))
