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

- ;; History:
-
- ;; Date Version Who Action
- ;; -------- ------- --- ----
- ;; 09/13/96 1.0 DC Created
- ;; 09/26/96 1.1 DC added syntax table stuff so now matches `'s
- ;; now can use C-c C-b to m4 on buffer,C-c C-r for region
- ;; added m4-comment-region (C-c C-c)
- ;; 09/27/96 1.2 DC Redid header comment
- ;; 1.3 DC more cosmetic fixes
- ;; 1.4 DC removed m4-comment-region, using comment-region instead
- ;; 10/03/96 DC added provide line
- ;; 10/24/96 1.5 DC fixed keyword regexp
- ;; 10/29/96 1.6 DC added m4_keywords for --prefix-builtins
- ;; fixed syntax table so _define_ isn't keywordified
- ;; 10/29/96 1.8 DC fixed a problem where comments go fontified incorrectly
- ;; if they had quotes in them
- ;; 11/21/96 1.9 DC collapsed 4 regexps into 1 and removed a duplicate,
- ;; removed a duplicate backslash
- ;; 05/16/97 1.10 DC added contributed fixes and enhancements from
- ;; Martin Buchholz
- ;; Can now specify options to m4 via m4-program-options
- ;; Now terminates m4 processes when the buffer send
- is
- ;; done
- ;; dnl and m4_dnl recognized as comment starters
-
- ;; To Do's:
-
- ;; * want to make m4-m4-(buffer|region) look sorta like M-x compile look&feel ?
- ;; * sexp motion commands don't seem to work right
-
- ;; to autoload m4 lisp code:
- ;; (autoload 'm4-mode "m4-mode" nil t)
- ;;
- ;; or can use (load "m4-mode") or (require 'm4-mode) to just load it
- ;;
- ;; to try to "auto-detect" m4 files:
- ;; (setq auto-mode-alist
- ;; (cons '(".*\\.m4$" . m4-mode)
- ;; auto-mode-alist))
