28 | ;;; Commentary: |
29 | ||
30 | ;; The latest version of this package should be available from | |
31 | ;; <URL:http://wombat.doc.ic.ac.uk/emacs/browse-url.el>. | |
32 | ||
33 | ;; This package provides functions which read a URL (Uniform Resource | |
34 | ;; Locator) from the minibuffer, defaulting to the URL around point, | |
35 | ;; and ask a World-Wide Web browser to load it. It can also load the | |
36 | ;; URL associated with the current buffer. Different browsers use | |
37 | ;; different methods of remote control so there is one function for | |
38 | ;; each supported browser. If the chosen browser is not running, it | |
39 | ;; is started. Currently there is support for: | |
40 | ||
41 | ;; Function Browser Earliest version | |
42 | ;; browse-url-netscape Netscape 1.1b1 | |
43 | ;; browse-url-mosaic XMosaic <= 2.4 | |
44 | ;; browse-url-cci XMosaic 2.5 | |
45 | ;; browse-url-w3 w3 0 | |
46 | ;; browse-url-iximosaic IXI Mosaic ? | |
47 | ||
48 | ;; Note that versions of Netscape before 1.1b1 did not have remote | |
49 | ;; control. <URL:http://home.netscape.com/newsref/std/x-remote.html> | |
50 | ;; and <URL:http://home.netscape.com/info/APIs/>. | |
51 | ||
52 | ;; Netscape can cache Web pages so it may be necessary to tell it to | |
53 | ;; reload the current page if it has changed (eg. if you have edited | |
54 | ;; it). There is currently no perfect automatic solution to this. | |
55 | ||
56 | ;; Netscape allows you to specify the id of the window you want to | |
57 | ;; control but which window DO you want to control and how do you | |
58 | ;; discover its id? | |
59 | ||
60 | ;; If using XMosaic before version 2.5, check the definition of | |
61 | ;; browse-url-usr1-signal below. | |
62 | ;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/remote-control.html> | |
63 | ||
64 | ;; XMosaic version 2.5 introduced Common Client Interface allowing you | |
65 | ;; to control mosaic through Unix sockets. | |
66 | ;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/CCI/cci-spec.html> | |
67 | ||
68 | ;; William M. Perry's excellent "w3" WWW browser for | |
69 | ;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/> | |
70 | ;; has a function w3-follow-url-at-point, but that | |
71 | ;; doesn't let you edit the URL like browse-url. | |
72 | ||
73 | ;; I recommend Nelson Minar <nelson@santafe.edu>'s excellent | |
74 | ;; html-helper-mode.el for editing HTML and thank Nelson for | |
75 | ;; his many useful comments on this code. | |
76 | ;; <URL:http://www.santafe.edu/~nelson/hhm-beta/> | |
77 | ||
78 | ;; This package generalises function html-previewer-process in Marc | |
79 | ;; Andreessen <marca@ncsa.uiuc.edu>'s html-mode (LCD | |
80 | ;; modes/html-mode.el.Z) and provides better versions of the URL | |
81 | ;; functions in Michelangelo Grigni <mic@cs.ucsd.edu>'s ffap.el | |
82 | ;; (find-file-at-point) <URL:ftp://cs.ucsd.edu:/pub/mic/>. The huge | |
83 | ;; hyperbole package also contains similar functions. | |
84 | ||
85 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
86 | ;; Help! | |
87 | ||
88 | ;; Can you write and test some code for the Macintrash and Windoze | |
89 | ;; Netscape remote control APIs? (See the URL above). | |
90 | ||
91 | ;; Do any other browsers have remote control? | |

94 | ;; Usage | |
95 | ||
96 | ;; To display the URL at or before point: | |
97 | ;; M-x browse-url-at-point RET | |
98 | ||
99 | ;; To display a URL by shift-clicking on it, put this in your ~/.emacs | |
100 | ;; file: | |
a5f6b207 RS |
101 | ;; (global-set-key [S-mouse-2] 'browse-url-at-mouse) |
102 | ;; (Note that using Shift-mouse-1 is not desirable because | |
103 | ;; that event has a standard meaning in Emacs.) | |
a69315a1 RS |
104 | |
105 | ;; To display the current buffer in a web browser: | |
106 | ;; M-x browse-url-of-buffer RET | |
107 | ||
108 | ;; In Dired, to display the file named on the current line: | |
109 | ;; M-x browse-url-of-dired-file RET | |
110 | ||
111 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
112 | ;; Customisation (~/.emacs) | |
113 | ||
114 | ;; To see what variables are available for customization, type `M-x | |
115 | ;; set-variable browse-url TAB'. | |
116 | ||
117 | ;; To bind the browse-url commands to keys with the `C-c u' prefix: | |
118 | ;; (global-set-key "\C-cu." 'browse-url-at-point) | |
119 | ;; (global-set-key "\C-cub" 'browse-url-of-buffer) | |
120 | ;; (global-set-key "\C-cuf" 'browse-url-of-file) | |
121 | ;; (add-hook 'dired-mode-hook | |
0521259a EN |
122 | ;; (lambda () |
123 | ;; (local-set-key "\C-cuf" 'browse-url-of-dired-file)))) | |
a69315a1 RS |
124 | ;; (if (boundp 'browse-url-browser-function) |
125 | ;; (global-set-key "\C-cuu" browse-url-browser-function) | |
126 | ;; (eval-after-load | |
127 | ;; "browse-url" | |
128 | ;; '(global-set-key "\C-cuu" browse-url-browser-function))) | |
129 | ||
130 | ;; To use the Emacs w3 browser when not running under X11: | |
131 | ;; (if (not (eq window-system 'x)) | |
132 | ;; (setq browse-url-browser-function 'browse-url-w3)) | |
133 | ||
134 | ;; To always save modified buffers before displaying the file in a browser: | |
135 | ;; (setq browse-url-save-file t) | |
136 | ||
137 | ;; To get round the Netscape caching problem, you could try either of | |
138 | ;; the following (but not both). EITHER write-file in | |
139 | ;; html-helper-mode makes Netscape reload document: | |
140 | ;; | |
141 | ;; (autoload 'browse-url-netscape-reload "browse-url" | |
142 | ;; "Ask a WWW browser to redisplay the current file." t) | |
143 | ;; (add-hook 'html-helper-mode-hook | |
144 | ;; (function (lambda () | |
145 | ;; (add-hook 'local-write-file-hooks | |
146 | ;; (function (lambda () | |
147 | ;; (let ((local-write-file-hooks)) | |
148 | ;; (save-buffer)) | |
149 | ;; (browse-url-netscape-reload) | |
0521259a EN |
150 | ;; t)) ; => file written by hook |
151 | ;; t)))) ; append to l-w-f-hooks | |
a69315a1 RS |
152 | ;; |
153 | ;; [Does this work for html-mode too?] | |
154 | ;; | |
155 | ;; OR browse-url-of-file ask Netscape to load and then reload the | |
156 | ;; file: | |
157 | ;; | |
158 | ;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload) | |
159 | ||
160 | ;; You may also want to customise browse-url-netscape-arguments, eg. | |
161 | ;; | |
162 | ;; (setq browse-url-netscape-arguments '("-install")) | |
163 | ;; | |
164 | ;; or similarly for the other browsers. | |
