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51 ;; prerequisites, which targets are out-of-date, and which have no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

503 \\{makefile-browser-map}
505 Makefile mode can be configured by modifying the following variables:
507 `makefile-browser-buffer-name':
508 Name of the macro- and target browser buffer.
510 `makefile-target-colon':
511 The string that gets appended to all target names
512 inserted by `makefile-insert-target'.
513 \":\" or \"::\" are quite common values.
515 `makefile-macro-assign':
516 The string that gets appended to all macro names
517 inserted by `makefile-insert-macro'.
518 The normal value should be \" = \", since this is what
519 standard make expects. However, newer makes such as dmake
520 allow a larger variety of different macro assignments, so you
521 might prefer to use \" += \" or \" := \" .
523 `makefile-tab-after-target-colon':
524 If you want a TAB (instead of a space) to be appended after the
525 target colon, then set this to a non-nil value.
527 `makefile-browser-leftmost-column':
528 Number of blanks to the left of the browser selection mark.
530 `makefile-browser-cursor-column':
531 Column in which the cursor is positioned when it moves
532 up or down in the browser.
534 `makefile-browser-selected-mark':
535 String used to mark selected entries in the browser.
537 `makefile-browser-unselected-mark':
538 String used to mark unselected entries in the browser.
540 `makefile-browser-auto-advance-after-selection-p':
541 If this variable is set to a non-nil value the cursor
542 will automagically advance to the next line after an item
543 has been selected in the browser.
545 `makefile-pickup-everything-picks-up-filenames-p':
546 If this variable is set to a non-nil value then
547 `makefile-pickup-everything' also picks up filenames as targets
548 (i.e. it calls `makefile-pickup-filenames-as-targets'), otherwise
549 filenames are omitted.
551 `makefile-cleanup-continuations':
552 If this variable is set to a non-nil value then Makefile mode
553 will assure that no line in the file ends with a backslash
554 (the continuation character) followed by any whitespace.
555 This is done by silently removing the trailing whitespace, leaving
556 the backslash itself intact.
557 IMPORTANT: Please note that enabling this option causes Makefile mode
558 to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\".
560 `makefile-browser-hook':
561 A function or list of functions to be called just before the
562 browser is entered. This is executed in the makefile buffer.
564 `makefile-special-targets-list':
565 List of special targets. You will be offered to complete
566 on one of those in the minibuffer whenever you enter a `.'.
567 at the beginning of a line in Makefile mode."
