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

60 | ;; [A version of the Netscape browser is now free software | |
61 | ;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is | |
62 | ;; reasonable to have that as the default.] | |
63 | ||
64 | ;; Note that versions of Netscape before 1.1b1 did not have remote | |
65 | ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>. | |
66 | ||
67 | ;; Browsers can cache Web pages so it may be necessary to tell them to | |
68 | ;; reload the current page if it has changed (e.g. if you have edited | |
69 | ;; it). There is currently no perfect automatic solution to this. | |
70 | ||
71 | ;; Netscape allows you to specify the id of the window you want to | |
72 | ;; control but which window DO you want to control and how do you | |
73 | ;; discover its id? | |

75 | ;; William M. Perry's excellent "w3" WWW browser for |
76 | ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/> | |
77 | ;; has a function w3-follow-url-at-point, but that | |
78 | ;; doesn't let you edit the URL like browse-url. | |
79 | ;; The `gnuserv' package that can be used to control it in another | |
80 | ;; Emacs process is available from | |
81 | ;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>. | |
82 | ||
83 | ;; Grail is the freely available WWW browser implemented in Python, a | |
84 | ;; cool object-oriented freely available interpreted language. Grail | |
85 | ;; 0.3b1 was the first version to have remote control as distributed. | |
86 | ;; For more information on Grail see | |
87 | ;; <URL:http://grail.cnri.reston.va.us/> and for more information on | |
88 | ;; Python see <url:http://www.python.org/>. Grail support in | |

121 | ;; Help! | |
122 | ||
123 | ;; Can you write and test some code for the Macintrash and Windoze | |
124 | ;; Netscape remote control APIs? (See the URL above). | |
125 | ||
126 | ;; Do any other browsers have remote control? | |
127 | ||
128 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
129 | ;; Usage | |
130 | ||
131 | ;; To display the URL at or before point: | |
132 | ;; M-x browse-url-at-point RET | |
133 | ;; or, similarly but with the opportunity to edit the URL extracted from | |
134 | ;; the buffer, use: | |
135 | ;; M-x browse-url | |
136 | ||
137 | ;; To display a URL by shift-clicking on it, put this in your ~/.emacs | |
138 | ;; file: | |
139 | ;; (global-set-key [S-mouse-2] 'browse-url-at-mouse) | |
140 | ;; (Note that using Shift-mouse-1 is not desirable because | |
141 | ;; that event has a standard meaning in Emacs.) | |
142 | ||
143 | ;; To display the current buffer in a web browser: | |
144 | ;; M-x browse-url-of-buffer RET | |
145 | ||
146 | ;; To display the current region in a web browser: | |
147 | ;; M-x browse-url-of-region RET | |
148 | ||
149 | ;; In Dired, to display the file named on the current line: | |
150 | ;; M-x browse-url-of-dired-file RET | |
151 | ||
152 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
153 | ;; Customisation (~/.emacs) | |
154 | ||
155 | ;; To see what variables are available for customization, type | |
156 | ;; `M-x set-variable browse-url TAB'. Better, use | |
157 | ;; `M-x customize-group browse-url'. | |
158 | ||
159 | ;; Bind the browse-url commands to keys with the `C-c C-z' prefix | |
160 | ;; (as used by html-helper-mode): | |
161 | ;; (global-set-key "\C-c\C-z." 'browse-url-at-point) | |
162 | ;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer) | |
163 | ;; (global-set-key "\C-c\C-zr" 'browse-url-of-region) | |
164 | ;; (global-set-key "\C-c\C-zu" 'browse-url) | |
165 | ;; (global-set-key "\C-c\C-zv" 'browse-url-of-file) | |
166 | ;; (add-hook 'dired-mode-hook | |

202 | ;; | |
