|

|
36 ;; A major mode for editing makefiles. The mode knows about Makefile
|
|
|
37 ;; syntax and defines M-n and M-p to move to next and previous productions.
|
|
|
38 ;;
|
|
|
39 ;; The keys $, =, : and . are electric; they try to help you fill in a
|
|
|
40 ;; macro reference, macro definition, ordinary target name, or special
|
|
|
41 ;; target name, respectively. Such names are completed using a list of
|
|
|
42 ;; targets and macro names parsed out of the makefile. This list is
|
|
|
43 ;; automatically updated, if necessary, whenever you invoke one of
|
|
|
44 ;; these commands. You can force it to be updated with C-c C-p.
|
|
|
45 ;;
|
|
|
46 ;; The command C-c C-f adds certain filenames in the current directory
|
|
|
47 ;; as targets. You can filter out filenames by setting the variable
|
|
|
48 ;; makefile-ignored-files-in-pickup-regex.
|
|
|
49 ;;
|
|
|
50 ;; The command C-c C-u grinds for a bit, then pops up a report buffer
|
|
|
51 ;; showing which target names are up-to-date with respect to their
|
|
|
52 ;; prerequisites, which targets are out-of-date, and which have no
|
|
|
53 ;; prerequisites.
|
|
|
54 ;;
|
|
|
55 ;; The command C-c C-b pops up a browser window listing all target and
|
|
|
56 ;; macro names. You can mark or unmark items wit C-c SPC, and insert
|
|
|
57 ;; all marked items back in the Makefile with C-c TAB.
|
|
|
58 ;;
|
|
|
59 ;; The command C-c TAB in the makefile buffer inserts a GNU make builtin.
|
|
|
60 ;; You will be prompted for the builtin's args.
|
|
|
61 ;;
|
|
|
62 ;; There are numerous other customization variables.
|
|
|
63
|
|
|
64 ;;
|
|
|
65 ;; To Do:
|
|
|
66 ;;
|
|
|
67 ;; * makefile-backslash-region should be given better behavior.
|
|
|
68 ;; * Consider binding C-c C-c to comment-region (like cc-mode).
|
|
|
69 ;; * Eliminate electric stuff entirely.
|
|
|
70 ;; * It might be nice to highlight targets differently depending on
|
|
|
71 ;; whether they are up-to-date or not. Not sure how this would
|
|
|
72 ;; interact with font-lock.
|
|
|
73 ;; * Would be nice to edit the commands in ksh-mode and have
|
|
|
74 ;; indentation and slashification done automatically. Hard.
|
|
|
75 ;; * Consider removing browser mode. It seems useless.
|
|
|
76 ;; * ":" should notice when a new target is made and add it to the
|
|
|
77 ;; list (or at least set makefile-need-target-pickup).
|
|
|
78 ;; * Make browser into a major mode.
|
|
|
79 ;; * Clean up macro insertion stuff. It is a mess.
|
|
|
80 ;; * Browser entry and exit is weird. Normalize.
|
|
|
81 ;; * Browser needs to be rewritten. Right now it is kind of a crock.
|
|
|
82 ;; Should at least:
|
|
|
83 ;; * Act more like dired/buffer menu/whatever.
|
|
|
84 ;; * Highlight as mouse traverses.
|
|
|
85 ;; * B2 inserts.
|
|
|
86 ;; * Update documentation above.
|
|
|
87 ;; * Update texinfo manual.
|
|
|
88 ;; * Update files.el.

|

510
|
|
|
511 makefile-browser-buffer-name:
|
|
|
512 Name of the macro- and target browser buffer.
|
|
|
513
|
|
|
514 makefile-target-colon:
|
|
|
515 The string that gets appended to all target names
|
|
|
516 inserted by `makefile-insert-target'.
|
|
|
517 \":\" or \"::\" are quite common values.
|
|
|
518
|
|
|
519 makefile-macro-assign:
|
|
|
520 The string that gets appended to all macro names
|
|
|
521 inserted by `makefile-insert-macro'.
|
|
|
522 The normal value should be \" = \", since this is what
|
|
|
523 standard make expects. However, newer makes such as dmake
|
|
|
524 allow a larger variety of different macro assignments, so you
|
|
|
525 might prefer to use \" += \" or \" := \" .
|
|
|
526
|
|
|
527 makefile-tab-after-target-colon:
|
|
|
528 If you want a TAB (instead of a space) to be appended after the
|
|
|
529 target colon, then set this to a non-nil value.
|
|
|
530
|
|
|
531 makefile-browser-leftmost-column:
|
|
|
532 Number of blanks to the left of the browser selection mark.
|
|
|
533
|
|
|
534 makefile-browser-cursor-column:
|
|
|
535 Column in which the cursor is positioned when it moves
|
|
|
536 up or down in the browser.
|
|
|
537
|
|
|
538 makefile-browser-selected-mark:
|
|
|
539 String used to mark selected entries in the browser.
|
|
|
540
|
|
|
541 makefile-browser-unselected-mark:
|
|
|
542 String used to mark unselected entries in the browser.
|
|
|
543
|
|
|
544 makefile-browser-auto-advance-after-selection-p:
|
|
|
545 If this variable is set to a non-nil value the cursor
|
|
|
546 will automagically advance to the next line after an item
|
|
|
547 has been selected in the browser.
|
|
|
548
|
|
|
549 makefile-pickup-everything-picks-up-filenames-p:
|
|
|
550 If this variable is set to a non-nil value then
|
|
|
551 `makefile-pickup-everything' also picks up filenames as targets
|
|
|
552 (i.e. it calls `makefile-find-filenames-as-targets'), otherwise
|
|
|
553 filenames are omitted.
|
|
|
554
|
|
|
555 makefile-cleanup-continuations-p:
|
|
|
556 If this variable is set to a non-nil value then makefile-mode
|
|
|
557 will assure that no line in the file ends with a backslash
|
|
|
558 (the continuation character) followed by any whitespace.
|
|
|
559 This is done by silently removing the trailing whitespace, leaving
|
|
|
560 the backslash itself intact.
|
|
|
561 IMPORTANT: Please note that enabling this option causes makefile-mode
|
|
|
562 to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\".
|
|
|
563
|
|
|
564 makefile-browser-hook:
|
|
|
565 A function or list of functions to be called just before the

|
|
566 browser is entered. This is executed in the makefile buffer.
|
|
|
567
|
|
|
568 makefile-special-targets-list:

569 List of special targets. You will be offered to complete
