- ;; This needs work. The electric characters are too obnoxious.
- ;; It should not define C-c LETTER.
- ;; It should support knowing the list of existing macros and targets
- ;; via M-TAB completion, not by preempting insertion of references.
- ;; Also, the doc strings need fixing: the first line doesn't stand alone,
- ;; and other usage is not high quality. Symbol names don't have `...'.
- ;; The Mode names is written as makefile-mode instead of Makefile mode.
-
- ;; So, for the meantime, this is not the default mode for makefiles.

- ;;; Commentary:
-
- ;; A major mode for editing makefiles. The mode knows about Makefile
- ;; syntax and defines M-n and M-p to move to next and previous productions.
- ;;
- ;; The keys $, =, : and . are electric; they try to help you fill in a
- ;; macro reference, macro definition, ordinary target name, or special
- ;; target name, respectively. Such names are completed using a list of
- ;; targets and macro names parsed out of the makefile. This list is
- ;; automatically updated, if necessary, whenever you invoke one of
- ;; these commands. You can force it to be updated with C-c C-p.
- ;;
- ;; The command C-c f adds certain filenames in the current directory
- ;; as targets. You can filter out filenames by setting the variable
- ;; makefile-ignored-files-in-pickup-regex.
- ;;
- ;; The command C-c C-u grinds for a bit, then pops up a report buffer
- ;; showing which target names are up-to-date with respect to their
- ;; prerequisites, which targets are out-of-date, and which have no
- ;; prerequisites.
- ;;
- ;; The command C-c b pops up a browser window listing all target and
- ;; macro names. You can mark or unmark items wit C-c SPC, and insert
- ;; all marked items back in the Makefile with C-c TAB.
- ;;
- ;; The command C-c TAB in the makefile buffer inserts a GNU make builtin.
- ;; You will be prompted for the builtin's args.
- ;;
- ;; There are numerous other customization variables.
