|

|
||
;;; 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;; prerequisites, which targets are out-of-date, and which have no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:
|
||
;;
|
||
;; * 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.

|
||
makefile-tab-after-target-colon:
|
||
If you want a TAB (instead of a space) to be appended after the
|
||
target colon, then set this to a non-nil value.
|
||
|
||
makefile-browser-leftmost-column:
|
||
Number of blanks to the left of the browser selection mark.
|
||
|
||
makefile-browser-cursor-column:
|
||
Column in which the cursor is positioned when it moves
|
||
up or down in the browser.
|
||
|
||
makefile-browser-selected-mark:
|
||
String used to mark selected entries in the browser.
|
||
|
||
makefile-browser-unselected-mark:
|
||
String used to mark unselected entries in the browser.
|
||
|
||
makefile-browser-auto-advance-after-selection-p:
|
||
If this variable is set to a non-nil value the cursor
|
||
will automagically advance to the next line after an item
|
||
has been selected in the browser.
|
||
|
||
makefile-pickup-everything-picks-up-filenames-p:
|
||
If this variable is set to a non-nil value then
|
||
`makefile-pickup-everything' also picks up filenames as targets
|
||
(i.e. it calls `makefile-find-filenames-as-targets'), otherwise
|
||
filenames are omitted.
|
||
|
||
makefile-cleanup-continuations-p:
|
||
If this variable is set to a non-nil value then makefile-mode
|
||
will assure that no line in the file ends with a backslash
|
||
(the continuation character) followed by any whitespace.
|
||
This is done by silently removing the trailing whitespace, leaving
|
||
the backslash itself intact.
|
||
IMPORTANT: Please note that enabling this option causes makefile-mode
|
||
to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\".
|
||
|
||
makefile-browser-hook:
|
||
A function or list of functions to be called just before the
|
||
browser is entered. This is executed in the makefile buffer.
|
||
|
||
makefile-special-targets-list:
|
||
List of special targets. You will be offered to complete
|

on one of those in the minibuffer whenever you enter a `.'.
