29 ;;; Commentary:
31 ;; A major mode for editing makefiles. The mode knows about Makefile
32 ;; syntax and defines M-n and M-p to move to next and previous productions.
34 ;; The keys $, =, : and . are electric; they try to help you fill in a
35 ;; macro reference, macro definition, ordinary target name, or special
36 ;; target name, respectively. Such names are completed using a list of
37 ;; targets and macro names parsed out of the makefile. This list is
38 ;; automatically updated, if necessary, whenever you invoke one of
39 ;; these commands. You can force it to be updated with C-c C-p.
41 ;; The command C-c C-f adds certain filenames in the current directory
42 ;; as targets. You can filter out filenames by setting the variable
43 ;; makefile-ignored-files-in-pickup-regex.
45 ;; The command C-c C-u grinds for a bit, then pops up a report buffer
46 ;; showing which target names are up-to-date with respect to their
47 ;; prerequisites, which targets are out-of-date, and which have no
48 ;; prerequisites.
50 ;; The command C-c C-b pops up a browser window listing all target and
51 ;; macro names. You can mark or unmark items with C-c SPC, and insert
52 ;; all marked items back in the Makefile with C-c TAB.
54 ;; The command C-c TAB in the makefile buffer inserts a GNU make builtin.
55 ;; You will be prompted for the builtin's args.
57 ;; There are numerous other customization variables.
60 ;; To Do:
62 ;; * Add missing doc strings, improve terse doc strings.
63 ;; * Eliminate electric stuff entirely.
64 ;; * It might be nice to highlight targets differently depending on
65 ;; whether they are up-to-date or not. Not sure how this would
66 ;; interact with font-lock.
67 ;; * Would be nice to edit the commands in ksh-mode and have
68 ;; indentation and slashification done automatically. Hard.
69 ;; * Consider removing browser mode. It seems useless.
70 ;; * ":" should notice when a new target is made and add it to the
71 ;; list (or at least set makefile-need-target-pickup).
72 ;; * Make browser into a major mode.
73 ;; * Clean up macro insertion stuff. It is a mess.
74 ;; * Browser entry and exit is weird. Normalize.
75 ;; * Browser needs to be rewritten. Right now it is kind of a crock.
76 ;; Should at least:
77 ;; * Act more like dired/buffer menu/whatever.
78 ;; * Highlight as mouse traverses.
79 ;; * B2 inserts.
80 ;; * Update documentation above.
81 ;; * Update texinfo manual.
82 ;; * Update files.el.
86 ;;; Code:
88 ;; Sadly we need this for a macro.

779 "Major mode for editing standard Makefiles.
781 If you are editing a file for a different make, try one of the
782 variants `makefile-automake-mode', `makefile-gmake-mode',
783 `makefile-makepp-mode', `makefile-bsdmake-mode' or,
784 `makefile-imake-mode'. All but the last should be correctly
785 chosen based on the file name, except if it is *.mk. This
786 function ends by invoking the function(s) `makefile-mode-hook'.
788 It is strongly recommended to use `font-lock-mode', because that
789 provides additional parsing information. This is used for
790 example to see that a rule action `echo foo: bar' is a not rule
791 dependency, despite the colon.
793 \\{makefile-mode-map}
795 In the browser, use the following keys:
797 \\{makefile-browser-map}
799 Makefile mode can be configured by modifying the following variables:
801 `makefile-browser-buffer-name':
802 Name of the macro- and target browser buffer.
804 `makefile-target-colon':
805 The string that gets appended to all target names
806 inserted by `makefile-insert-target'.
807 \":\" or \"::\" are quite common values.
809 `makefile-macro-assign':
810 The string that gets appended to all macro names
811 inserted by `makefile-insert-macro'.
812 The normal value should be \" = \", since this is what
813 standard make expects. However, newer makes such as dmake
814 allow a larger variety of different macro assignments, so you
815 might prefer to use \" += \" or \" := \" .
817 `makefile-tab-after-target-colon':
818 If you want a TAB (instead of a space) to be appended after the
819 target colon, then set this to a non-nil value.
821 `makefile-browser-leftmost-column':
822 Number of blanks to the left of the browser selection mark.
824 `makefile-browser-cursor-column':
825 Column in which the cursor is positioned when it moves
826 up or down in the browser.
828 `makefile-browser-selected-mark':
829 String used to mark selected entries in the browser.
831 `makefile-browser-unselected-mark':
832 String used to mark unselected entries in the browser.
834 `makefile-browser-auto-advance-after-selection-p':
835 If this variable is set to a non-nil value the cursor
836 will automagically advance to the next line after an item
837 has been selected in the browser.
839 `makefile-pickup-everything-picks-up-filenames-p':
840 If this variable is set to a non-nil value then
841 `makefile-pickup-everything' also picks up filenames as targets
842 (i.e. it calls `makefile-pickup-filenames-as-targets'), otherwise
843 filenames are omitted.
845 `makefile-cleanup-continuations':
846 If this variable is set to a non-nil value then Makefile mode
847 will assure that no line in the file ends with a backslash
848 (the continuation character) followed by any whitespace.
849 This is done by silently removing the trailing whitespace, leaving
850 the backslash itself intact.
851 IMPORTANT: Please note that enabling this option causes Makefile mode
852 to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\".
854 `makefile-browser-hook':
855 A function or list of functions to be called just before the
856 browser is entered. This is executed in the makefile buffer.
858 `makefile-special-targets-list':
859 List of special targets. You will be offered to complete
860 on one of those in the minibuffer whenever you enter a `.'.
861 at the beginning of a line in Makefile mode."
