31 ;; The latest version of this package should be available from
32 ;; <URL:http://wombat.doc.ic.ac.uk/emacs/browse-url.el>.
34 ;; This package provides functions which read a URL (Uniform Resource
35 ;; Locator) from the minibuffer, defaulting to the URL around point,
36 ;; and ask a World-Wide Web browser to load it. It can also load the
37 ;; URL associated with the current buffer. Different browsers use
38 ;; different methods of remote control so there is one function for
39 ;; each supported browser. If the chosen browser is not running, it
40 ;; is started. Currently there is support for:
42 ;; Function Browser Earliest version
43 ;; browse-url-netscape Netscape 1.1b1
44 ;; browse-url-mosaic XMosaic <= 2.4
45 ;; browse-url-cci XMosaic 2.5
47 ;; browse-url-iximosaic IXI Mosaic ?
48 ;; browse-url-lynx-* Lynx 0
50 ;; Note that versions of Netscape before 1.1b1 did not have remote
51 ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>
52 ;; and <URL:http://www.netscape.com/info/APIs/>.
54 ;; Netscape can cache Web pages so it may be necessary to tell it to
55 ;; reload the current page if it has changed (e.g. if you have edited
56 ;; it). There is currently no perfect automatic solution to this.
58 ;; Netscape allows you to specify the id of the window you want to
59 ;; control but which window DO you want to control and how do you
62 ;; If using XMosaic before version 2.5, check the definition of
63 ;; browse-url-usr1-signal below.
64 ;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/remote-control.html>
66 ;; XMosaic version 2.5 introduced Common Client Interface allowing you
67 ;; to control mosaic through Unix sockets.
68 ;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/CCI/cci-spec.html>
70 ;; William M. Perry's excellent "w3" WWW browser for
71 ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
72 ;; has a function w3-follow-url-at-point, but that
73 ;; doesn't let you edit the URL like browse-url.
75 ;; I recommend Nelson Minar <nelson@santafe.edu>'s excellent
76 ;; html-helper-mode.el for editing HTML and thank Nelson for
77 ;; his many useful comments on this code.
78 ;; <URL:http://www.santafe.edu/~nelson/hhm-beta/>
80 ;; This package generalises function html-previewer-process in Marc
81 ;; Andreessen <marca@ncsa.uiuc.edu>'s html-mode (LCD
82 ;; modes/html-mode.el.Z) and provides better versions of the URL
83 ;; functions in Michelangelo Grigni <mic@cs.ucsd.edu>'s ffap.el
84 ;; (find-file-at-point) <URL:ftp://cs.ucsd.edu:/pub/mic/>. The huge
85 ;; hyperbole package also contains similar functions.
87 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
90 ;; Can you write and test some code for the Macintrash and Windoze
91 ;; Netscape remote control APIs? (See the URL above).
93 ;; Do any other browsers have remote control?
95 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
98 ;; Put the following in your ~/.emacs file:
100 ;; (autoload 'browse-url-at-point "browse-url"
101 ;; "Ask a WWW browser to load the URL at or before point." t)
102 ;; (autoload 'browse-url-at-mouse "browse-url"

109 ;; "In Dired, ask a WWW browser to display the file named on this line." t)
111 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
114 ;; To display the URL at or before point:
115 ;; M-x browse-url-at-point RET
117 ;; To display a URL by shift-clicking on it, put this in your ~/.emacs
119 ;; (global-set-key [S-mouse-1] 'browse-url-at-mouse)
121 ;; To display the current buffer in a web browser:

128 ;; Customisation (~/.emacs)
130 ;; To see what variables are available for customization, type `M-x
131 ;; set-variable browse-url TAB'.
133 ;; To bind the browse-url commands to keys with the `C-c C-z' prefix
134 ;; (as used by html-helper-mode):
135 ;; (global-set-key "\C-c\C-z." 'browse-url-at-point)
136 ;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer)
137 ;; (global-set-key "\C-c\C-zv" 'browse-url-of-file)
138 ;; (add-hook 'dired-mode-hook
139 ;; (function (lambda ()
140 ;; (local-set-key "\C-c\C-zf" 'browse-url-of-dired-file))))
142 ;; To browse URLs in mail messages by clicking mouse-2:
143 ;; (add-hook 'rmail-mode-hook (function (lambda () ; rmail-mode startup
144 ;; (define-key rmail-mode-map [mouse-2] 'browse-url-at-mouse))))
146 ;; To use the Emacs w3 browser when not running under X11:
147 ;; (or (eq window-system 'x)
148 ;; (setq browse-url-browser-function 'browse-url-w3))
150 ;; To always save modified buffers before displaying the file in a browser:
151 ;; (setq browse-url-save-file t)
153 ;; To get round the Netscape caching problem, you could try either of
154 ;; the following (but not both). EITHER write-file in
155 ;; html-helper-mode makes Netscape reload the document:
157 ;; (autoload 'browse-url-netscape-reload "browse-url"
158 ;; "Ask a WWW browser to redisplay the current file." t)
159 ;; (add-hook 'html-helper-mode-hook
160 ;; (function (lambda ()
161 ;; (add-hook 'local-write-file-hooks
162 ;; (function (lambda ()
163 ;; (let ((local-write-file-hooks))
165 ;; (browse-url-netscape-reload)
166 ;; t)) ; => file written by hook
167 ;; t)))) ; append to l-w-f-hooks
169 ;; [Does this work for html-mode too?]
171 ;; OR browse-url-of-file asks Netscape to load and then reload the
174 ;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload)
176 ;; You may also want to customise browse-url-netscape-arguments, e.g.
177 ;; (setq browse-url-netscape-arguments '("-install"))
179 ;; or similarly for the other browsers.
