29 | ;; This package provides functions which read a URL (Uniform Resource | |
30 | ;; Locator) from the minibuffer, defaulting to the URL around point, | |
31 | ;; and ask a World-Wide Web browser to load it. It can also load the | |
32 | ;; URL associated with the current buffer. Different browsers use | |
33 | ;; different methods of remote control so there is one function for | |
34 | ;; each supported browser. If the chosen browser is not running, it | |
3abc9fa1 DL |
35 | ;; is started. Currently there is support for the following browsers, |
36 | ;; some of them probably now obsolete: | |

51 | ;; [A version of the Netscape browser is now free software | |
52 | ;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is | |
53 | ;; reasonable to have that as the default.] | |
54 | ||
55 | ;; Note that versions of Netscape before 1.1b1 did not have remote | |
56 | ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>. | |
57 | ||
58 | ;; Browsers can cache Web pages so it may be necessary to tell them to | |
59 | ;; reload the current page if it has changed (e.g. if you have edited | |
60 | ;; it). There is currently no perfect automatic solution to this. | |
61 | ||
62 | ;; Netscape allows you to specify the id of the window you want to | |
63 | ;; control but which window DO you want to control and how do you | |
64 | ;; discover its id? | |
65 | ||
66 | ;; If using XMosaic before version 2.5, check the definition of | |
67 | ;; browse-url-usr1-signal below. | |
68 | ;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/remote-control.html> | |
69 | ||
70 | ;; XMosaic version 2.5 introduced Common Client Interface allowing you | |
71 | ;; to control mosaic through Unix sockets. | |

74 | ;; William M. Perry's excellent "w3" WWW browser for | |
75 | ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/> | |
76 | ;; has a function w3-follow-url-at-point, but that | |
77 | ;; doesn't let you edit the URL like browse-url. | |
78 | ;; The `gnuserv' package that can be used to control it in another | |
79 | ;; Emacs process is available from | |
80 | ;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>. | |

82 | ;; Grail is the freely available WWW browser implemented in Python, a | |
83 | ;; cool object-oriented freely available interpreted language. Grail | |
84 | ;; 0.3b1 was the first version to have remote control as distributed. | |
85 | ;; For more information on Grail see | |
86 | ;; <URL:http://grail.cnri.reston.va.us/> and for more information on | |
87 | ;; Python see <url:http://www.python.org/>. Grail support in | |
88 | ;; browse-url.el written by Barry Warsaw <bwarsaw@python.org>. | |
89 | ||
90 | ;; MMM is a semi-free WWW browser implemented in Objective Caml, an | |
91 | ;; interesting impure functional programming language. See | |
92 | ;; <URL:http://pauillac.inria.fr/%7Erouaix/mmm/>. | |
93 | ||
94 | ;; Lynx is now distributed by the FSF. See also | |

97 | ;; Free graphical browsers that could be used by `browse-url-generic' | |
98 | ;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and | |
99 | ;; <URL:http://www.unlv.edu/chimera/>, Arena | |
100 | ;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya | |

102 | ;; <URL:ftp://sig.enst.fr/pub/multicast/mMosaic/>, | |
103 | ;; <URL:http://sig.enst.fr/~dauphin/mMosaic/> (with development | |
104 | ;; support for Java applets and multicast) can be used like Mosaic by | |
105 | ;; setting `browse-url-mosaic-program' appropriately. | |

107 | ;; I [Denis Howe, not Dave Love] recommend Nelson Minar | |

124 | ;; Help! | |

132 | ;; Usage | |
133 | ||
134 | ;; To display the URL at or before point: | |
135 | ;; M-x browse-url-at-point RET | |
136 | ;; or, similarly but with the opportunity to edit the URL extracted from | |
137 | ;; the buffer, use: | |
138 | ;; M-x browse-url | |
139 | ||
140 | ;; To display a URL by shift-clicking on it, put this in your ~/.emacs | |
141 | ;; file: | |
142 | ;; (global-set-key [S-mouse-2] 'browse-url-at-mouse) | |
143 | ;; (Note that using Shift-mouse-1 is not desirable because | |
144 | ;; that event has a standard meaning in Emacs.) | |
145 | ||
146 | ;; To display the current buffer in a web browser: | |
147 | ;; M-x browse-url-of-buffer RET | |
148 | ||
149 | ;; To display the current region in a web browser: | |
150 | ;; M-x browse-url-of-region RET | |
151 | ||
152 | ;; In Dired, to display the file named on the current line: | |
153 | ;; M-x browse-url-of-dired-file RET | |
154 | ||
155 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
156 | ;; Customisation (~/.emacs) | |
157 | ||
158 | ;; To see what variables are available for customization, type | |
159 | ;; `M-x set-variable browse-url TAB'. Better, use | |
160 | ;; `M-x customize-group browse-url'. | |
161 | ||
162 | ;; Bind the browse-url commands to keys with the `C-c C-z' prefix | |
163 | ;; (as used by html-helper-mode): | |
164 | ;; (global-set-key "\C-c\C-z." 'browse-url-at-point) | |
