;;; Commentary:
|
|
|
|
;; The latest version of this package should be available from
|
|
;; <URL:http://wombat.doc.ic.ac.uk/emacs/browse-url.el>.
|
|
|
|
;; This package provides functions which read a URL (Uniform Resource
|
|
;; Locator) from the minibuffer, defaulting to the URL around point,
|
|
;; and ask a World-Wide Web browser to load it. It can also load the
|
|
;; URL associated with the current buffer. Different browsers use
|
|
;; different methods of remote control so there is one function for
|
|
;; each supported browser. If the chosen browser is not running, it
|
|
;; is started. Currently there is support for:
|
|
|
|
;; Function Browser Earliest version
|
|
;; browse-url-netscape Netscape 1.1b1
|
|
;; browse-url-mosaic XMosaic <= 2.4
|
|
;; browse-url-cci XMosaic 2.5
|
|
;; browse-url-w3 w3 0
|
|
;; browse-url-iximosaic IXI Mosaic ?
|
|
;; browse-url-lynx-* Lynx 0
|
|
;; browse-url-grail Grail 0.3b1
|
|
|
|
;; Note that versions of Netscape before 1.1b1 did not have remote
|
|
;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>
|
|
;; and <URL:http://www.netscape.com/info/APIs/>.
|
|
|
|
;; Netscape can cache Web pages so it may be necessary to tell it to
|
|
;; reload the current page if it has changed (e.g. if you have edited
|
|
;; it). There is currently no perfect automatic solution to this.
|
|
|
|
;; Netscape allows you to specify the id of the window you want to
|
|
;; control but which window DO you want to control and how do you
|
|
;; discover its id?
|
|
|
|
;; If using XMosaic before version 2.5, check the definition of
|
|
;; browse-url-usr1-signal below.
|
|
;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/remote-control.html>
|
|
|
|
;; XMosaic version 2.5 introduced Common Client Interface allowing you
|
|
;; to control mosaic through Unix sockets.
|
|
;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/CCI/cci-spec.html>
|
|
|
|
;; William M. Perry's excellent "w3" WWW browser for
|
|
;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
|
|
;; has a function w3-follow-url-at-point, but that
|
|
;; doesn't let you edit the URL like browse-url.
|
|
|
|
;; I recommend Nelson Minar <nelson@santafe.edu>'s excellent
|
|
;; html-helper-mode.el for editing HTML and thank Nelson for
|
|
;; his many useful comments on this code.
|
|
;; <URL:http://www.santafe.edu/~nelson/hhm-beta/>
|
|
|
|
;; This package generalises function html-previewer-process in Marc
|
|
;; Andreessen <marca@ncsa.uiuc.edu>'s html-mode (LCD
|
|
;; modes/html-mode.el.Z) and provides better versions of the URL
|
|
;; functions in Michelangelo Grigni <mic@cs.ucsd.edu>'s ffap.el
|
|
;; (find-file-at-point) <URL:ftp://cs.ucsd.edu:/pub/mic/>. The huge
|
|
;; hyperbole package also contains similar functions.
|
|
|
|
;; Grail is the freely available WWW browser implemented in Python, a
|
|
;; cool object-oriented freely available interpreted language. Grail
|
|
;; 0.3b1 was the first version to have remote control as distributed.
|
|
;; For more information on Grail see
|
|
;; <URL:http://monty.cnri.reston.va.us/> and for more information on
|
|
;; Python see <url:http://www.python.org/>. Grail support in
|
|
;; browse-url.el written by Barry Warsaw <bwarsaw@python.org>.

|
|
;; Help!
|
|
|
|
;; Can you write and test some code for the Macintrash and Windoze
|
|
;; Netscape remote control APIs? (See the URL above).
|
|
|
|
;; Do any other browsers have remote control?
|
|

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
|
|
;; Usage
|
|
|
|
;; To display the URL at or before point:
|
|
;; M-x browse-url-at-point RET
|
|
|
|
;; To display a URL by shift-clicking on it, put this in your ~/.emacs
|
|
;; file:
|
|
;; (global-set-key [S-mouse-2] 'browse-url-at-mouse)
|
|
;; (Note that using Shift-mouse-1 is not desirable because
|
|
;; that event has a standard meaning in Emacs.)
|
|
|
|
;; To display the current buffer in a web browser:
|
|
;; M-x browse-url-of-buffer RET
|
|
|
|
;; In Dired, to display the file named on the current line:
|
|
;; M-x browse-url-of-dired-file RET
|
|
|
|
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
|
|
;; Customisation (~/.emacs)
|
|
|
|
;; To see what variables are available for customization, type
|
|
;; `M-x set-variable browse-url TAB'.
|
|
|
|
;; Bind the browse-url commands to keys with the `C-c C-z' prefix
|
|
;; (as used by html-helper-mode):
|
|
;; (global-set-key "\C-c\C-z." 'browse-url-at-point)
|
|
;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer)
|
|
;; (global-set-key "\C-c\C-zu" 'browse-url)
|
|
;; (global-set-key "\C-c\C-zv" 'browse-url-of-file)
|
|
;; (add-hook 'dired-mode-hook
|
|
;; (function (lambda ()
|
|
;; (local-set-key "\C-c\C-zf" 'browse-url-of-dired-file))))
|
|
|
|
;; Browse URLs in mail messages by clicking mouse-2:
|
|
;; (add-hook 'rmail-mode-hook (function (lambda () ; rmail-mode startup
|
|
;; (define-key rmail-mode-map [mouse-2] 'browse-url-at-mouse))))
|
|
|
|
;; Browse URLs in Usenet messages by clicking mouse-2:
|
|
;; (eval-after-load "gnus"
|
|
;; '(define-key gnus-article-mode-map [mouse-2] 'browse-url-at-mouse))
|
|
|
|
;; Use the Emacs w3 browser when not running under X11:
|
|
;; (or (eq window-system 'x)
|
|
;; (setq browse-url-browser-function 'browse-url-w3))
|
|
|
|
;; To always save modified buffers before displaying the file in a browser:
|
|
;; (setq browse-url-save-file t)
|
|
|
|
;; To get round the Netscape caching problem, you could EITHER have
|
|
;; write-file in html-helper-mode make Netscape reload the document:
|
|
;;
|
|
;; (autoload 'browse-url-netscape-reload "browse-url"
|
|
;; "Ask a WWW browser to redisplay the current file." t)
|
|
;; (add-hook 'html-helper-mode-hook
|
|
;; (function (lambda ()
|
|
;; (add-hook 'local-write-file-hooks
|
|
;; (function (lambda ()
|
|
;; (let ((local-write-file-hooks))
|
|
;; (save-buffer))
|
|
;; (browse-url-netscape-reload)
|
|
;; t)) ; => file written by hook
|
|
;; t)))) ; append to l-w-f-hooks
|
|
;;
|
|
;; OR have browse-url-of-file ask Netscape to load and then reload the
|
|
;; file:
|
|
;;
|
|
;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload)
|
|
|
|
;; You may also want to customise browse-url-netscape-arguments, e.g.
|
|
;; (setq browse-url-netscape-arguments '("-install"))
|
|
;;
|
|
;; or similarly for the other browsers.
