30 | ;; A major mode for editing makefiles. The mode knows about Makefile |
31 | ;; syntax and defines M-n and M-p to move to next and previous productions. | |
32 | ;; | |
33 | ;; The keys $, =, : and . are electric; they try to help you fill in a | |
34 | ;; macro reference, macro definition, ordinary target name, or special | |
35 | ;; target name, respectively. Such names are completed using a list of | |
36 | ;; targets and macro names parsed out of the makefile. This list is | |
37 | ;; automatically updated, if necessary, whenever you invoke one of | |
38 | ;; these commands. You can force it to be updated with C-c C-p. | |
39 | ;; | |
6783b1ce | 40 | ;; The command C-c C-f adds certain filenames in the current directory |
9e9bf716 ER |
41 | ;; as targets. You can filter out filenames by setting the variable |
42 | ;; makefile-ignored-files-in-pickup-regex. | |
43 | ;; | |
44 | ;; The command C-c C-u grinds for a bit, then pops up a report buffer | |
45 | ;; showing which target names are up-to-date with respect to their | |
46 | ;; prerequisites, which targets are out-of-date, and which have no | |
47 | ;; prerequisites. | |
48 | ;; | |
6783b1ce | 49 | ;; The command C-c C-b pops up a browser window listing all target and |
10f518f7 | 50 | ;; macro names. You can mark or unmark items with C-c SPC, and insert |
9e9bf716 ER |
51 | ;; all marked items back in the Makefile with C-c TAB. |
52 | ;; | |
53 | ;; The command C-c TAB in the makefile buffer inserts a GNU make builtin. | |
54 | ;; You will be prompted for the builtin's args. | |
55 | ;; | |
56 | ;; There are numerous other customization variables. | |

58 | ;; |
59 | ;; To Do: | |
60 | ;; | |
e008a4e5 | 61 | ;; * Add missing doc strings, improve terse doc strings. |
6783b1ce RS |
62 | ;; * Eliminate electric stuff entirely. |
63 | ;; * It might be nice to highlight targets differently depending on | |
64 | ;; whether they are up-to-date or not. Not sure how this would | |
65 | ;; interact with font-lock. | |
66 | ;; * Would be nice to edit the commands in ksh-mode and have | |
67 | ;; indentation and slashification done automatically. Hard. | |
68 | ;; * Consider removing browser mode. It seems useless. | |
69 | ;; * ":" should notice when a new target is made and add it to the | |
70 | ;; list (or at least set makefile-need-target-pickup). | |
308a2860 | 71 | ;; * Make browser into a major mode. |
6783b1ce RS |
72 | ;; * Clean up macro insertion stuff. It is a mess. |
73 | ;; * Browser entry and exit is weird. Normalize. | |
74 | ;; * Browser needs to be rewritten. Right now it is kind of a crock. | |
75 | ;; Should at least: | |
76 | ;; * Act more like dired/buffer menu/whatever. | |
77 | ;; * Highlight as mouse traverses. | |
78 | ;; * B2 inserts. | |
79 | ;; * Update documentation above. | |
80 | ;; * Update texinfo manual. | |
81 | ;; * Update files.el. | |

702 | "Major mode for editing standard Makefiles. |
703 | ||
704 | If you are editing a file for a different make, try one of the | |
705 | variants `makefile-automake-mode', `makefile-gmake-mode', | |
706 | `makefile-makepp-mode' or `makefile-bsdmake-mode'. All but the | |
707 | last should be correctly chosen based on the file name, except if | |
708 | it is *.mk. This function ends by invoking the function(s) | |
709 | `makefile-mode-hook'. | |
72c0ae01 | 710 | |
92984345 DP |
711 | It is strongly recommended to use `font-lock-mode', because that |
712 | provides additional parsing information. This is used for | |
713 | example to see that a rule action `echo foo: bar' is a not rule | |
714 | dependency, despite the colon. | |

72c0ae01 ER |

718 | In the browser, use the following keys: | |
719 | ||
720 | \\{makefile-browser-map} | |
721 | ||
bd0e4eb1 | 722 | Makefile mode can be configured by modifying the following variables: |
72c0ae01 | 723 | |
debe2de2 | 724 | `makefile-browser-buffer-name': |
72c0ae01 ER |
725 | Name of the macro- and target browser buffer. |
726 | ||
debe2de2 | 727 | `makefile-target-colon': |
72c0ae01 | 728 | The string that gets appended to all target names |
bd0e4eb1 | 729 | inserted by `makefile-insert-target'. |
72c0ae01 ER |
730 | \":\" or \"::\" are quite common values. |
731 | ||
debe2de2 | 732 | `makefile-macro-assign': |
72c0ae01 | 733 | The string that gets appended to all macro names |
bd0e4eb1 | 734 | inserted by `makefile-insert-macro'. |
72c0ae01 | 735 | The normal value should be \" = \", since this is what |
a564ebfc | 736 | standard make expects. However, newer makes such as dmake |
72c0ae01 ER |
737 | allow a larger variety of different macro assignments, so you |
738 | might prefer to use \" += \" or \" := \" . | |
739 | ||
debe2de2 | 740 | `makefile-tab-after-target-colon': |
72c0ae01 ER |
741 | If you want a TAB (instead of a space) to be appended after the |
742 | target colon, then set this to a non-nil value. | |
743 | ||
debe2de2 | 744 | `makefile-browser-leftmost-column': |
72c0ae01 ER |
745 | Number of blanks to the left of the browser selection mark. |
746 | ||
debe2de2 | 747 | `makefile-browser-cursor-column': |
72c0ae01 ER |
748 | Column in which the cursor is positioned when it moves |
749 | up or down in the browser. | |
750 | ||
debe2de2 | 751 | `makefile-browser-selected-mark': |
72c0ae01 ER |
752 | String used to mark selected entries in the browser. |
753 | ||
debe2de2 | 754 | `makefile-browser-unselected-mark': |
72c0ae01 ER |
755 | String used to mark unselected entries in the browser. |
756 | ||
debe2de2 | 757 | `makefile-browser-auto-advance-after-selection-p': |
72c0ae01 ER |
758 | If this variable is set to a non-nil value the cursor |
759 | will automagically advance to the next line after an item | |
760 | has been selected in the browser. | |
761 | ||
debe2de2 | 762 | `makefile-pickup-everything-picks-up-filenames-p': |
72c0ae01 | 763 | If this variable is set to a non-nil value then |
bd0e4eb1 | 764 | `makefile-pickup-everything' also picks up filenames as targets |
b20a44dc | 765 | (i.e. it calls `makefile-pickup-filenames-as-targets'), otherwise |
72c0ae01 ER |
766 | filenames are omitted. |
767 | ||
e006b3cd | 768 | `makefile-cleanup-continuations': |
a564ebfc | 769 | If this variable is set to a non-nil value then Makefile mode |
72c0ae01 ER |
770 | will assure that no line in the file ends with a backslash |
771 | (the continuation character) followed by any whitespace. | |
772 | This is done by silently removing the trailing whitespace, leaving | |
773 | the backslash itself intact. | |
a564ebfc | 774 | IMPORTANT: Please note that enabling this option causes Makefile mode |
bd0e4eb1 | 775 | to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\". |
72c0ae01 | 776 | |
debe2de2 | 777 | `makefile-browser-hook': |
72c0ae01 | 778 | A function or list of functions to be called just before the |
9e9bf716 | 779 | browser is entered. This is executed in the makefile buffer. |
72c0ae01 | 780 | |
debe2de2 | 781 | `makefile-special-targets-list': |
72c0ae01 | 782 | List of special targets. You will be offered to complete |
bd0e4eb1 RS |
783 | on one of those in the minibuffer whenever you enter a `.'. |
784 | at the beginning of a line in Makefile mode." | |
