- ;;; 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 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- ;; prerequisites, which targets are out-of-date, and which have no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 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.
-
- ;;
- ;; To Do:
- ;;
- ;; * makefile-backslash-region should be given better behavior.
- ;; * Consider binding C-c C-c to comment-region (like cc-mode).
- ;; * Eliminate electric stuff entirely.
- ;; * It might be nice to highlight targets differently depending on
- ;; whether they are up-to-date or not. Not sure how this would
- ;; interact with font-lock.
- ;; * Would be nice to edit the commands in ksh-mode and have
- ;; indentation and slashification done automatically. Hard.
- ;; * Consider removing browser mode. It seems useless.
- ;; * ":" should notice when a new target is made and add it to the
- ;; list (or at least set makefile-need-target-pickup).
- ;; * Make browser into a major mode.
- ;; * Clean up macro insertion stuff. It is a mess.
- ;; * Browser entry and exit is weird. Normalize.
- ;; * Browser needs to be rewritten. Right now it is kind of a crock.
- ;; Should at least:
- ;; * Act more like dired/buffer menu/whatever.
- ;; * Highlight as mouse traverses.
- ;; * B2 inserts.
- ;; * Update documentation above.
- ;; * Update texinfo manual.
- ;; * Update files.el.
