26 | ;; PURPOSE: | |
98d775e5 DL |
27 | ;; This package features a function called ff-find-other-file, which performs |
28 | ;; the following function: | |
2be55c9c RS |
29 | ;; |
30 | ;; When in a .c file, find the first corresponding .h file in a set | |
31 | ;; of directories and display it, and vice-versa from the .h file. | |
32 | ;; | |
33 | ;; Many people maintain their include file in a directory separate to their | |
34 | ;; src directory, and very often you may be editing a file and have a need to | |
35 | ;; visit the "other file". This package searches through a set of directories | |
36 | ;; to find that file. | |
37 | ;; | |
38 | ;; THE "OTHER FILE", or "corresponding file", generally has the same basename, | |
98d775e5 | 39 | ;; and just has a different extension as described by the ff-other-file-alist |
2be55c9c RS |
40 | ;; variable: |
41 | ;; | |
42 | ;; '(("\\.cc$" (".hh" ".h")) | |
43 | ;; ("\\.hh$" (".cc" ".C" ".CC" ".cxx" ".cpp"))) | |
44 | ;; | |
45 | ;; If the current file has a .cc extension, ff-find-other-file will attempt | |
46 | ;; to look for a .hh file, and then a .h file in some directory as described | |
47 | ;; below. The mechanism here is to replace the matched part of the original | |
48 | ;; filename with each of the corresponding extensions in turn. | |
49 | ;; | |
50 | ;; Alternatively, there are situations where the filename of the other file | |
51 | ;; cannot be determined easily with regexps. For example, a .c file may | |
52 | ;; have two corresponding .h files, for its public and private parts, or | |
53 | ;; the filename for the .c file contains part of the pathname of the .h | |
54 | ;; file, as between src/fooZap.cc and include/FOO/zap.hh. In that case, the | |
55 | ;; format above can be changed to include a function to be called when the | |
56 | ;; current file matches the regexp: | |
57 | ;; | |
71796940 | 58 | ;; '(("\\.cc$" cc--function) |
2be55c9c RS |
59 | ;; ("\\.hh$" hh-function)) |
60 | ;; | |
98d775e5 DL |
61 | ;; These functions must return a list consisting of the possible names of the |
62 | ;; corresponding file, with or without path. There is no real need for more | |
2be55c9c RS |
63 | ;; than one function, and one could imagine the following value for cc-other- |
64 | ;; file-alist: | |
65 | ;; | |
66 | ;; (setq cc-other-file-alist | |
67 | ;; '(("\\.cc$" ff-cc-hh-converter) | |
68 | ;; ("\\.hh$" ff-cc-hh-converter) | |
69 | ;; ("\\.c$" (".h")) | |
70 | ;; ("\\.h$" (".c" ".cc" ".C" ".CC" ".cxx" ".cpp")))) | |
71296446 | 71 | ;; |
2be55c9c | 72 | ;; ff-cc-hh-converter is included at the end of this file as a reference. |
71296446 | 73 | ;; |
2be55c9c RS |
74 | ;; SEARCHING is carried out in a set of directories specified by the |
75 | ;; ff-search-directories variable: | |
76 | ;; | |
77 | ;; ("." "../../src" "../include/*" "/usr/local/*/src/*" "$PROJECT/src") | |
78 | ;; | |
79 | ;; This means that the corresponding file will be searched for first in | |
80 | ;; the current directory, then in ../../src, then in one of the directories | |
81 | ;; under ../include, and so on. The star is _not_ a general wildcard | |
82 | ;; character: it just indicates that the subdirectories of this directory | |
83 | ;; must each be searched in turn. Environment variables will be expanded in | |
84 | ;; the ff-search-directories variable. | |
85 | ;; | |
86 | ;; If the point is on a #include line, the file to be #included is searched | |
87 | ;; for in the same manner. This can be disabled with the ff-ignore-include | |
88 | ;; variable, or by calling ff-get-other-file instead of ff-find-other-file. | |
89 | ;; | |
90 | ;; If the file was not found, ff-find-other-file will prompt you for where | |
91 | ;; to create the new "corresponding file" (defaults to the current directory), | |
98d775e5 | 92 | ;; unless the variable ff-always-try-to-create is set to nil. |
2be55c9c | 93 | ;; |
98d775e5 DL |
94 | ;; GIVEN AN ARGUMENT (with the ^U prefix), ff-find-other-file will get the |
95 | ;; other file in another (the other?) window (see find-file-other-window and | |
96 | ;; switch-to-buffer-other-window). This can be set on a more permanent basis | |
97 | ;; by setting ff-always-in-other-window to t in which case the ^U prefix will | |
2be55c9c RS |
98 | ;; do the opposite of what was described above. |
99 | ;; | |
100 | ;; THERE ARE FIVE AVAILABLE HOOKS, called in this order if non-nil: | |
101 | ;; | |
03741cc5 SM |
102 | ;; - ff-pre-find-hook - called before the search for the other file starts |
103 | ;; - ff-not-found-hook - called when the other file could not be found | |
104 | ;; - ff-pre-load-hook - called just before the other file is 'loaded' | |
105 | ;; - ff-file-created-hook - called when the other file is created | |
106 | ;; - ff-post-load-hook - called just after the other file is 'loaded' | |
2be55c9c | 107 | ;; |
03741cc5 | 108 | ;; The *load-hook allow you to place point where you want it in the other |
98d775e5 | 109 | ;; file. |
