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: | |

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.] | |
59 | ||
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>. | |
62 | ||
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. | |
66 | ||
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 | |
69 | ;; discover its id? | |

73 | ;; has a function w3-follow-url-at-point, but that | |

109 | ;; Help! | |
110 | ||
111 | ;; Can you write and test some code for the Macintrash and Windoze | |
112 | ;; Netscape remote control APIs? (See the URL above). | |
113 | ||
114 | ;; Do any other browsers have remote control? | |
115 | ||
116 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
117 | ;; Usage | |
118 | ||
119 | ;; To display the URL at or before point: | |
120 | ;; M-x browse-url-at-point RET | |
121 | ;; or, similarly but with the opportunity to edit the URL extracted from | |
122 | ;; the buffer, use: | |
123 | ;; M-x browse-url | |
124 | ||
125 | ;; To display a URL by shift-clicking on it, put this in your ~/.emacs | |
126 | ;; file: | |
127 | ;; (global-set-key [S-mouse-2] 'browse-url-at-mouse) | |
128 | ;; (Note that using Shift-mouse-1 is not desirable because | |
129 | ;; that event has a standard meaning in Emacs.) | |
130 | ||
131 | ;; To display the current buffer in a web browser: | |
132 | ;; M-x browse-url-of-buffer RET | |
133 | ||
134 | ;; To display the current region in a web browser: | |
135 | ;; M-x browse-url-of-region RET | |
136 | ||
137 | ;; In Dired, to display the file named on the current line: | |
138 | ;; M-x browse-url-of-dired-file RET | |
139 | ||
140 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
141 | ;; Customisation (~/.emacs) | |
142 | ||
143 | ;; To see what variables are available for customization, type | |
144 | ;; `M-x set-variable browse-url TAB'. Better, use | |
145 | ;; `M-x customize-group browse-url'. | |
146 | ||
147 | ;; Bind the browse-url commands to keys with the `C-c C-z' prefix | |
148 | ;; (as used by html-helper-mode): | |
149 | ;; (global-set-key "\C-c\C-z." 'browse-url-at-point) | |
150 | ;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer) | |
151 | ;; (global-set-key "\C-c\C-zr" 'browse-url-of-region) | |
152 | ;; (global-set-key "\C-c\C-zu" 'browse-url) | |
153 | ;; (global-set-key "\C-c\C-zv" 'browse-url-of-file) | |
154 | ;; (add-hook 'dired-mode-hook | |
155 | ;; (lambda () | |
