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. | |
33 | ;; | |
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. | |
40 | ;; | |
6783b1ce | 41 | ;; The command C-c C-f adds certain filenames in the current directory |
9e9bf716 ER |
42 | ;; as targets. You can filter out filenames by setting the variable |
43 | ;; makefile-ignored-files-in-pickup-regex. | |
44 | ;; | |
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47 | ;; prerequisites, which targets are out-of-date, and which have no | |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. | |
49 | ;; | |
6783b1ce | 50 | ;; The command C-c C-b pops up a browser window listing all target and |
10f518f7 | 51 | ;; macro names. You can mark or unmark items with C-c SPC, and insert |
9e9bf716 ER |
52 | ;; all marked items back in the Makefile with C-c TAB. |
53 | ;; | |
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. | |
56 | ;; | |
57 | ;; There are numerous other customization variables. | |

60 | ;; To Do: | |
61 | ;; | |
e008a4e5 | 62 | ;; * Add missing doc strings, improve terse doc strings. |
6783b1ce RS |
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). | |
308a2860 | 72 | ;; * Make browser into a major mode. |
6783b1ce RS |
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. | |

704 | "Major mode for editing standard Makefiles. |
705 | ||
706 | If you are editing a file for a different make, try one of the | |
707 | variants `makefile-automake-mode', `makefile-gmake-mode', | |
708 | `makefile-makepp-mode' or `makefile-bsdmake-mode'. All but the | |
709 | last should be correctly chosen based on the file name, except if | |
710 | it is *.mk. This function ends by invoking the function(s) | |
711 | `makefile-mode-hook'. | |
72c0ae01 | 712 | |
92984345 DP |
713 | It is strongly recommended to use `font-lock-mode', because that |
714 | provides additional parsing information. This is used for | |
715 | example to see that a rule action `echo foo: bar' is a not rule | |
716 | dependency, despite the colon. | |
717 | ||
72c0ae01 ER |
718 | \\{makefile-mode-map} |
719 | ||
720 | In the browser, use the following keys: | |
721 | ||
722 | \\{makefile-browser-map} | |
723 | ||
bd0e4eb1 | 724 | Makefile mode can be configured by modifying the following variables: |
72c0ae01 | 725 | |
debe2de2 | 726 | `makefile-browser-buffer-name': |
72c0ae01 ER |
727 | Name of the macro- and target browser buffer. |
728 | ||
debe2de2 | 729 | `makefile-target-colon': |
72c0ae01 | 730 | The string that gets appended to all target names |
bd0e4eb1 | 731 | inserted by `makefile-insert-target'. |
72c0ae01 ER |
732 | \":\" or \"::\" are quite common values. |
733 | ||
debe2de2 | 734 | `makefile-macro-assign': |
72c0ae01 | 735 | The string that gets appended to all macro names |
bd0e4eb1 | 736 | inserted by `makefile-insert-macro'. |
72c0ae01 | 737 | The normal value should be \" = \", since this is what |
a564ebfc | 738 | standard make expects. However, newer makes such as dmake |
72c0ae01 ER |
739 | allow a larger variety of different macro assignments, so you |
740 | might prefer to use \" += \" or \" := \" . | |
741 | ||
debe2de2 | 742 | `makefile-tab-after-target-colon': |
72c0ae01 ER |
743 | If you want a TAB (instead of a space) to be appended after the |
744 | target colon, then set this to a non-nil value. | |
745 | ||
debe2de2 | 746 | `makefile-browser-leftmost-column': |
72c0ae01 ER |
747 | Number of blanks to the left of the browser selection mark. |
748 | ||
debe2de2 | 749 | `makefile-browser-cursor-column': |
72c0ae01 ER |
750 | Column in which the cursor is positioned when it moves |
751 | up or down in the browser. | |
752 | ||
debe2de2 | 753 | `makefile-browser-selected-mark': |
72c0ae01 ER |
754 | String used to mark selected entries in the browser. |
755 | ||
debe2de2 | 756 | `makefile-browser-unselected-mark': |
72c0ae01 ER |
757 | String used to mark unselected entries in the browser. |
758 | ||
debe2de2 | 759 | `makefile-browser-auto-advance-after-selection-p': |
72c0ae01 ER |
760 | If this variable is set to a non-nil value the cursor |
761 | will automagically advance to the next line after an item | |
762 | has been selected in the browser. | |
763 | ||
debe2de2 | 764 | `makefile-pickup-everything-picks-up-filenames-p': |
72c0ae01 | 765 | If this variable is set to a non-nil value then |
bd0e4eb1 | 766 | `makefile-pickup-everything' also picks up filenames as targets |
b20a44dc | 767 | (i.e. it calls `makefile-pickup-filenames-as-targets'), otherwise |
72c0ae01 ER |
768 | filenames are omitted. |
769 | ||
e006b3cd | 770 | `makefile-cleanup-continuations': |
a564ebfc | 771 | If this variable is set to a non-nil value then Makefile mode |
72c0ae01 ER |
772 | will assure that no line in the file ends with a backslash |
773 | (the continuation character) followed by any whitespace. | |
774 | This is done by silently removing the trailing whitespace, leaving | |
775 | the backslash itself intact. | |
a564ebfc | 776 | IMPORTANT: Please note that enabling this option causes Makefile mode |
bd0e4eb1 | 777 | to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\". |
72c0ae01 | 778 | |
debe2de2 | 779 | `makefile-browser-hook': |
72c0ae01 | 780 | A function or list of functions to be called just before the |
9e9bf716 | 781 | browser is entered. This is executed in the makefile buffer. |
72c0ae01 | 782 | |
debe2de2 | 783 | `makefile-special-targets-list': |
72c0ae01 | 784 | List of special targets. You will be offered to complete |
bd0e4eb1 RS |
785 | on one of those in the minibuffer whenever you enter a `.'. |
786 | at the beginning of a line in Makefile mode." | |
