;; 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
+;; macro names. You can mark or unmark items with 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.
;;
;; To Do:
;;
+;; * Add missing doc strings, improve terse doc strings.
;; * 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
;;; Code:
-(provide 'makefile)

Makefile mode can be configured by modifying the following variables:
-makefile-browser-buffer-name:
+`makefile-browser-buffer-name':
Name of the macro- and target browser buffer.
-makefile-target-colon:
+`makefile-target-colon':
The string that gets appended to all target names
inserted by `makefile-insert-target'.
\":\" or \"::\" are quite common values.
-makefile-macro-assign:
+`makefile-macro-assign':
The string that gets appended to all macro names
inserted by `makefile-insert-macro'.
The normal value should be \" = \", since this is what
- standard make expects. However, newer makes such as dmake
+ standard make expects. However, newer makes such as dmake
allow a larger variety of different macro assignments, so you
might prefer to use \" += \" or \" := \" .
-makefile-tab-after-target-colon:
+`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:
+`makefile-browser-leftmost-column':
Number of blanks to the left of the browser selection mark.
-makefile-browser-cursor-column:
+`makefile-browser-cursor-column':
Column in which the cursor is positioned when it moves
up or down in the browser.
-makefile-browser-selected-mark:
+`makefile-browser-selected-mark':
String used to mark selected entries in the browser.
-makefile-browser-unselected-mark:
+`makefile-browser-unselected-mark':
String used to mark unselected entries in the browser.
-makefile-browser-auto-advance-after-selection-p:
+`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:
+`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:

+`makefile-cleanup-continuations':
+ 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
+ IMPORTANT: Please note that enabling this option causes Makefile mode
to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\".
-makefile-browser-hook:
+`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:
+`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 `.'.
