29 ;; Command find-file-at-point replaces find-file. With a prefix, it
30 ;; behaves exactly like find-file. Without a prefix, it first tries
31 ;; to guess a default file or URL from the text around the point
32 ;; (`ffap-require-prefix' swaps these behaviors). This is useful for
33 ;; following references in situations such as mail or news buffers,
34 ;; README's, MANIFEST's, and so on. Submit bugs or suggestions with
37 ;; For the default installation, add this line to your init file:
39 ;; (ffap-bindings) ; do default key bindings
41 ;; ffap-bindings makes the following global key bindings:
43 ;; C-x C-f find-file-at-point (abbreviated as ffap)
44 ;; C-x C-r ffap-read-only
45 ;; C-x C-v ffap-alternate-file
47 ;; C-x d dired-at-point
48 ;; C-x C-d ffap-list-directory
50 ;; C-x 4 f ffap-other-window
51 ;; C-x 4 r ffap-read-only-other-window
52 ;; C-x 4 d ffap-dired-other-window
54 ;; C-x 5 f ffap-other-frame
55 ;; C-x 5 r ffap-read-only-other-frame
56 ;; C-x 5 d ffap-dired-other-frame
58 ;; S-mouse-3 ffap-at-mouse
59 ;; C-S-mouse-3 ffap-menu
61 ;; ffap-bindings also adds hooks to make the following local bindings
62 ;; in vm, gnus, and rmail:
64 ;; M-l ffap-next, or ffap-gnus-next in gnus (l == "link")
65 ;; M-m ffap-menu, or ffap-gnus-menu in gnus (m == "menu")
67 ;; If you do not like these bindings, modify the variable
68 ;; `ffap-bindings', or write your own.
70 ;; If you use ange-ftp, browse-url, complete, efs, or w3, it is best
71 ;; to load or autoload them before ffap. If you use ff-paths, load it
72 ;; afterwards. Try apropos {C-h a ffap RET} to get a list of the many
73 ;; option variables. In particular, if ffap is slow, try these:
75 ;; (setq ffap-alist nil) ; faster, dumber prompting
76 ;; (setq ffap-machine-p-known 'accept) ; no pinging
77 ;; (setq ffap-url-regexp nil) ; disable URL features in ffap
78 ;; (setq ffap-shell-prompt-regexp nil) ; disable shell prompt stripping
80 ;; ffap uses `browse-url' (if found, else `w3-fetch') to fetch URL's.
81 ;; For a hairier `ffap-url-fetcher', try ffap-url.el (same ftp site).
82 ;; Also, you can add `ffap-menu-rescan' to various hooks to fontify
83 ;; the file and URL references within a buffer.
88 ;; The History and Contributors moved to ffap.LOG (same ftp site),
89 ;; which also has some old examples and commentary from ffap 1.5.
94 ;; * let "/dir/file#key" jump to key (tag or regexp) in /dir/file
95 ;; * find file of symbol if TAGS is loaded (like above)
96 ;; * break long menus into multiple panes (like imenu?)
97 ;; * notice node in "(dired)Virtual Dired" (quotes, parentheses, whitespace)
98 ;; * notice "machine.dom blah blah blah dir/file" (how?)
99 ;; * as w3 becomes standard, rewrite to rely more on its functions
100 ;; * regexp options for ffap-string-at-point, like font-lock (MCOOK)
101 ;; * v19: could replace `ffap-locate-file' with a quieter `locate-library'
102 ;; * handle "$(VAR)" in Makefiles
