27;;; Commentary:
28;;
29;; The file-cache package is an attempt to make it easy to locate files
30;; by name, without having to remember exactly where they are located.
31;; This is very handy when working with source trees. You can also add
32;; frequently used files to the cache to create a hotlist effect.
33;; The cache can be used with any interactive command which takes a
34;; filename as an argument.
35;;
36;; It is worth noting that this package works best when most of the files
37;; in the cache have unique names, or (if they have the same name) exist in
38;; only a few directories. The worst case is many files all with
39;; the same name and in different directories, for example a big source tree
40;; with a Makefile in each directory. In such a case, you should probably
41;; use an alternate strategy to find the files.
42;;
43;; ADDING FILES TO THE CACHE:
44;;
45;; Use the following functions to add items to the file cache:
24ccf465 46;;
6b279740
RS
47;; * `file-cache-add-file': Adds a single file to the cache
48;;
49;; * `file-cache-add-file-list': Adds a list of files to the cache
50;;
51;; The following functions use the regular expressions in
52;; `file-cache-delete-regexps' to eliminate unwanted files:
24ccf465 53;;
6b279740
RS
54;; * `file-cache-add-directory': Adds the files in a directory to the
55;; cache. You can also specify a regular expression to match the files
56;; which should be added.
57;;
58;; * `file-cache-add-directory-list': Same as above, but acts on a list
59;; of directories. You can use `load-path', `exec-path' and the like.
60;;
61;; * `file-cache-add-directory-using-find': Uses the `find' command to
62;; add a directory tree to the cache.
63;;
64;; * `file-cache-add-directory-using-locate': Uses the `locate' command to
65;; add files matching a pattern to the cache.
66;;
67;; Use the function `file-cache-clear-cache' to remove all items from the
68;; cache. There are a number of `file-cache-delete' functions provided
69;; as well, but in general it is probably better to not worry too much
70;; about extra files in the cache.
71;;
72;; The most convenient way to initialize the cache is with an
b662c4bc
RS
73;; `eval-after-load' function, as noted in the ADDING FILES
74;; AUTOMATICALLY section.
6b279740
RS
75;;
76;; FINDING FILES USING THE CACHE:
77;;
78;; You can use the file-cache with any function that expects a filename as
79;; an argument. For example:
80;;
81;; 1) Invoke a function which expects a filename as an argument:
82;; M-x find-file
83;;
84;; 2) Begin typing a file name.
85;;
86;; 3) Invoke `file-cache-minibuffer-complete' (bound by default to
87;; C-TAB) to complete on the filename using the cache.
88;;
89;; 4) When you have found a unique completion, the minibuffer contents
90;; will change to the full name of that file.
24ccf465 91;;
6b279740
RS
92;; If there are a number of directories which contain the completion,
93;; invoking `file-cache-minibuffer-complete' repeatedly will cycle through
94;; them.
95;;
96;; 5) You can then edit the minibuffer contents, or press RETURN.
97;;
98;; It is much easier to simply try it than trying to explain it :)
99;;
b662c4bc 100;;; ADDING FILES AUTOMATICALLY
6b279740
RS
101;;
102;; For maximum utility, you should probably define an `eval-after-load'
103;; form which loads your favorite files:
104;;
24ccf465 105;; (eval-after-load
6b279740
RS
106;; "filecache"
107;; '(progn
108;; (message "Loading file cache...")
109;; (file-cache-add-directory-using-find "~/projects")
110;; (file-cache-add-directory-list load-path)
111;; (file-cache-add-directory "~/")
112;; (file-cache-add-file-list (list "~/foo/bar" "~/baz/bar"))
113;; ))
114;;
115;; If you clear and reload the cache frequently, it is probably easiest
116;; to put your initializations in a function:
117;;
24ccf465 118;; (eval-after-load
6b279740
RS
119;; "filecache"
120;; '(my-file-cache-initialize))
24ccf465 121;;
6b279740
RS
122;; (defun my-file-cache-initialize ()
123;; (interactive)
124;; (message "Loading file cache...")
125;; (file-cache-add-directory-using-find "~/projects")
126;; (file-cache-add-directory-list load-path)
127;; (file-cache-add-directory "~/")
128;; (file-cache-add-file-list (list "~/foo/bar" "~/baz/bar"))
129;; ))
130;;
131;; Of course, you can still add files to the cache afterwards, via
132;; Lisp functions.
