27 ;; This package provides functions which read a URL (Uniform Resource
28 ;; Locator) from the minibuffer, defaulting to the URL around point,
29 ;; and ask a World-Wide Web browser to load it. It can also load the
30 ;; URL associated with the current buffer. Different browsers use
31 ;; different methods of remote control so there is one function for
32 ;; each supported browser. If the chosen browser is not running, it
33 ;; is started. Currently there is support for the following browsers,
34 ;; some of them probably now obsolete:

56 ;; [A version of the Netscape browser is now free software
57 ;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is
58 ;; reasonable to have that as the default.]
60 ;; Note that versions of Netscape before 1.1b1 did not have remote
61 ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>.
63 ;; Browsers can cache Web pages so it may be necessary to tell them to
64 ;; reload the current page if it has changed (e.g. if you have edited
65 ;; it). There is currently no perfect automatic solution to this.
67 ;; Netscape allows you to specify the id of the window you want to
68 ;; control but which window DO you want to control and how do you
71 ;; William M. Perry's excellent "w3" WWW browser for
72 ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
73 ;; has a function w3-follow-url-at-point, but that
74 ;; doesn't let you edit the URL like browse-url.
75 ;; The `gnuserv' package that can be used to control it in another
76 ;; Emacs process is available from
77 ;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>.
79 ;; Lynx is now distributed by the FSF. See also
80 ;; <URL:http://lynx.browser.org/>.
82 ;; Free graphical browsers that could be used by `browse-url-generic'
83 ;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and
84 ;; <URL:http://www.unlv.edu/chimera/>, Arena
85 ;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya
86 ;; <URL:ftp://ftp.w3.org/pub/amaya>. mMosaic
87 ;; <URL:ftp://ftp.enst.fr/pub/mbone/mMosaic/>,
88 ;; <URL:http://www.enst.fr/~dauphin/mMosaic/> (with development
89 ;; support for Java applets and multicast) can be used like Mosaic by
90 ;; setting `browse-url-mosaic-program' appropriately.

153 ;; (add-hook 'dired-mode-hook
155 ;; (local-set-key "\C-c\C-zf" 'browse-url-of-dired-file)))
157 ;; Browse URLs in mail messages under RMAIL by clicking mouse-2:
158 ;; (add-hook 'rmail-mode-hook (lambda () ; rmail-mode startup
159 ;; (define-key rmail-mode-map [mouse-2] 'browse-url-at-mouse)))
160 ;; Alternatively, add `goto-address' to `rmail-show-message-hook'.

190 ;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload)
192 ;; You may also want to customize browse-url-netscape-arguments, e.g.
193 ;; (setq browse-url-netscape-arguments '("-install"))
195 ;; or similarly for the other browsers.
