;;; Commentary:
|
|
;;
|
|
;; The file-cache package is an attempt to make it easy to locate files
|
|
;; by name, without having to remember exactly where they are located.
|
|
;; This is very handy when working with source trees. You can also add
|
|
;; frequently used files to the cache to create a hotlist effect.
|
|
;; The cache can be used with any interactive command which takes a
|
|
;; filename as an argument.
|
|
;;
|
|
;; It is worth noting that this package works best when most of the files
|
|
;; in the cache have unique names, or (if they have the same name) exist in
|
|
;; only a few directories. The worst case is many files all with
|
|
;; the same name and in different directories, for example a big source tree
|
|
;; with a Makefile in each directory. In such a case, you should probably
|
|
;; use an alternate strategy to find the files.
|
|
;;
|
|
;; ADDING FILES TO THE CACHE:
|
|
;;
|
|
;; Use the following functions to add items to the file cache:
|
|
;;
|
|
;; * `file-cache-add-file': Adds a single file to the cache
|
|
;;
|
|
;; * `file-cache-add-file-list': Adds a list of files to the cache
|
|
;;
|
|
;; The following functions use the regular expressions in
|
|
;; `file-cache-filter-regexps' to eliminate unwanted files:
|
|
;;
|
|
;; * `file-cache-add-directory': Adds the files in a directory to the
|
|
;; cache. You can also specify a regular expression to match the files
|
|
;; which should be added.
|
|
;;
|
|
;; * `file-cache-add-directory-list': Same as above, but acts on a list
|
|
;; of directories. You can use `load-path', `exec-path' and the like.
|
|
;;
|
|
;; * `file-cache-add-directory-using-find': Uses the `find' command to
|
|
;; add a directory tree to the cache.
|
|
;;
|
|
;; * `file-cache-add-directory-using-locate': Uses the `locate' command to
|
|
;; add files matching a pattern to the cache.
|
|
;;
|
|
;; * `file-cache-add-directory-recursively': Uses the find-lisp package to
|
|
;; add all files matching a pattern to the cache.
|
|
;;
|
|
;; Use the function `file-cache-clear-cache' to remove all items from the
|
|
;; cache. There are a number of `file-cache-delete' functions provided
|
|
;; as well, but in general it is probably better to not worry too much
|
|
;; about extra files in the cache.
|
|
;;
|
|
;; The most convenient way to initialize the cache is with an
|
|
;; `eval-after-load' function, as noted in the ADDING FILES
|
|
;; AUTOMATICALLY section.
|
|
;;
|
|
;; FINDING FILES USING THE CACHE:
|
|
;;
|
|
;; You can use the file-cache with any function that expects a filename as
|
|
;; an argument. For example:
|
|
;;
|
|
;; 1) Invoke a function which expects a filename as an argument:
|
|
;; M-x find-file
|
|
;;
|
|
;; 2) Begin typing a file name.
|
|
;;
|
|
;; 3) Invoke `file-cache-minibuffer-complete' (bound by default to
|
|
;; C-TAB) to complete on the filename using the cache.
|
|
;;
|
|
;; 4) When you have found a unique completion, the minibuffer contents
|
|
;; will change to the full name of that file.
|
|
;;
|
|
;; If there are a number of directories which contain the completion,
|
|
;; invoking `file-cache-minibuffer-complete' repeatedly will cycle through
|
|
;; them.
|
|
;;
|
|
;; 5) You can then edit the minibuffer contents, or press RETURN.
|
|
;;
|
|
;; It is much easier to simply try it than trying to explain it :)
|
|
;;
|
|
;;; ADDING FILES AUTOMATICALLY
|
|
;;
|
|
;; For maximum utility, you should probably define an `eval-after-load'
|
|
;; form which loads your favorite files:
|
|
;;
|
|
;; (eval-after-load
|
|
;; "filecache"
|
|
;; '(progn
|
|
;; (message "Loading file cache...")
|
|
;; (file-cache-add-directory-using-find "~/projects")
|
|
;; (file-cache-add-directory-list load-path)
|
|
;; (file-cache-add-directory "~/")
|
|
;; (file-cache-add-file-list (list "~/foo/bar" "~/baz/bar"))
|
|
;; ))
|
|
;;
|
|
;; If you clear and reload the cache frequently, it is probably easiest
|
|
;; to put your initializations in a function:
|
|
;;
|
|
;; (eval-after-load
|
|
;; "filecache"
|
|
;; '(my-file-cache-initialize))
|
|
;;
|
|
;; (defun my-file-cache-initialize ()
|
|
;; (interactive)
|
|
;; (message "Loading file cache...")
|
|
;; (file-cache-add-directory-using-find "~/projects")
|
|
;; (file-cache-add-directory-list load-path)
|
|
;; (file-cache-add-directory "~/")
|
|
;; (file-cache-add-file-list (list "~/foo/bar" "~/baz/bar"))
|
|
;; ))
|
|
;;
|
|
;; Of course, you can still add files to the cache afterwards, via
|
|
;; Lisp functions.
|
|
;;
|
|
;; RELATED WORK:
|
|
;;
|
|
;; This package is a distant relative of Noah Friedman's fff utilities.
|
|
;; Our goal is pretty similar, but the implementation strategies are
|
|
;; different.
