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. | |
37 | ;; | |
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. | |
44 | ;; | |
6783b1ce | 45 | ;; The command C-c C-f adds certain filenames in the current directory |
9e9bf716 ER |
46 | ;; as targets. You can filter out filenames by setting the variable |
47 | ;; makefile-ignored-files-in-pickup-regex. | |
48 | ;; | |
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51 | ;; prerequisites, which targets are out-of-date, and which have no | |
52 | ;; prerequisites. | |
53 | ;; | |
6783b1ce | 54 | ;; The command C-c C-b pops up a browser window listing all target and |
9e9bf716 ER |
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. | |
57 | ;; | |
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. | |
60 | ;; | |
61 | ;; There are numerous other customization variables. | |

63 | ;; |
64 | ;; To Do: | |
65 | ;; | |
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). | |
308a2860 | 75 | ;; * Make browser into a major mode. |
6783b1ce RS |
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. | |
79 | ;; Should at least: | |
80 | ;; * Act more like dired/buffer menu/whatever. | |
81 | ;; * Highlight as mouse traverses. | |
82 | ;; * B2 inserts. | |
83 | ;; * Update documentation above. | |
84 | ;; * Update texinfo manual. | |
85 | ;; * Update files.el. | |

72c0ae01 ER |
474 | makefile-browser-buffer-name: |
475 | Name of the macro- and target browser buffer. | |

478 | The string that gets appended to all target names | |
bd0e4eb1 | 479 | inserted by `makefile-insert-target'. |
72c0ae01 ER |
480 | \":\" or \"::\" are quite common values. |

483 | The string that gets appended to all macro names | |
bd0e4eb1 | 484 | inserted by `makefile-insert-macro'. |
72c0ae01 ER |
485 | The normal value should be \" = \", since this is what |
486 | standard make expects. However, newer makes such as dmake | |
487 | allow a larger variety of different macro assignments, so you | |
488 | might prefer to use \" += \" or \" := \" . | |
489 | ||
490 | makefile-tab-after-target-colon: | |
491 | If you want a TAB (instead of a space) to be appended after the | |
492 | target colon, then set this to a non-nil value. | |
493 | ||
494 | makefile-browser-leftmost-column: | |
495 | Number of blanks to the left of the browser selection mark. | |
496 | ||
497 | makefile-browser-cursor-column: | |
498 | Column in which the cursor is positioned when it moves | |
499 | up or down in the browser. | |
500 | ||
501 | makefile-browser-selected-mark: | |
502 | String used to mark selected entries in the browser. | |

505 | String used to mark unselected entries in the browser. | |
506 | ||
507 | makefile-browser-auto-advance-after-selection-p: | |
508 | If this variable is set to a non-nil value the cursor | |
509 | will automagically advance to the next line after an item | |
510 | has been selected in the browser. | |
511 | ||
72c0ae01 ER |
512 | makefile-pickup-everything-picks-up-filenames-p: |

bd0e4eb1 | 514 | `makefile-pickup-everything' also picks up filenames as targets |
b20a44dc | 515 | (i.e. it calls `makefile-pickup-filenames-as-targets'), otherwise |
72c0ae01 ER |
516 | filenames are omitted. |
517 | ||
518 | makefile-cleanup-continuations-p: | |
519 | If this variable is set to a non-nil value then makefile-mode | |
520 | will assure that no line in the file ends with a backslash | |
521 | (the continuation character) followed by any whitespace. | |
522 | This is done by silently removing the trailing whitespace, leaving | |
523 | the backslash itself intact. | |
