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44 | ;; prerequisites, which targets are out-of-date, and which have no | |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

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

bd0e4eb1 | 804 | Makefile mode can be configured by modifying the following variables: |
72c0ae01 | 805 | |
debe2de2 | 806 | `makefile-browser-buffer-name': |
72c0ae01 ER |
807 | Name of the macro- and target browser buffer. |
808 | ||
debe2de2 | 809 | `makefile-target-colon': |
72c0ae01 | 810 | The string that gets appended to all target names |
bd0e4eb1 | 811 | inserted by `makefile-insert-target'. |
72c0ae01 ER |
812 | \":\" or \"::\" are quite common values. |
813 | ||
debe2de2 | 814 | `makefile-macro-assign': |
72c0ae01 | 815 | The string that gets appended to all macro names |
bd0e4eb1 | 816 | inserted by `makefile-insert-macro'. |
72c0ae01 | 817 | The normal value should be \" = \", since this is what |
a564ebfc | 818 | standard make expects. However, newer makes such as dmake |
72c0ae01 ER |
819 | allow a larger variety of different macro assignments, so you |
820 | might prefer to use \" += \" or \" := \" . | |
821 | ||
debe2de2 | 822 | `makefile-tab-after-target-colon': |
72c0ae01 ER |
823 | If you want a TAB (instead of a space) to be appended after the |
824 | target colon, then set this to a non-nil value. | |
825 | ||
debe2de2 | 826 | `makefile-browser-leftmost-column': |
72c0ae01 ER |
827 | Number of blanks to the left of the browser selection mark. |
828 | ||
debe2de2 | 829 | `makefile-browser-cursor-column': |
72c0ae01 ER |
830 | Column in which the cursor is positioned when it moves |
831 | up or down in the browser. | |
832 | ||
debe2de2 | 833 | `makefile-browser-selected-mark': |
72c0ae01 ER |
834 | String used to mark selected entries in the browser. |
835 | ||
debe2de2 | 836 | `makefile-browser-unselected-mark': |
72c0ae01 ER |
837 | String used to mark unselected entries in the browser. |
838 | ||
debe2de2 | 839 | `makefile-browser-auto-advance-after-selection-p': |
72c0ae01 ER |
840 | If this variable is set to a non-nil value the cursor |
841 | will automagically advance to the next line after an item | |
842 | has been selected in the browser. | |
843 | ||
debe2de2 | 844 | `makefile-pickup-everything-picks-up-filenames-p': |
72c0ae01 | 845 | If this variable is set to a non-nil value then |
bd0e4eb1 | 846 | `makefile-pickup-everything' also picks up filenames as targets |
b20a44dc | 847 | (i.e. it calls `makefile-pickup-filenames-as-targets'), otherwise |
72c0ae01 ER |
848 | filenames are omitted. |
849 | ||
e006b3cd | 850 | `makefile-cleanup-continuations': |
a564ebfc | 851 | If this variable is set to a non-nil value then Makefile mode |
72c0ae01 ER |
852 | will assure that no line in the file ends with a backslash |
853 | (the continuation character) followed by any whitespace. | |
854 | This is done by silently removing the trailing whitespace, leaving | |
855 | the backslash itself intact. | |
a564ebfc | 856 | IMPORTANT: Please note that enabling this option causes Makefile mode |
bd0e4eb1 | 857 | to MODIFY A FILE WITHOUT YOUR CONFIRMATION when \"it seems necessary\". |
