;;; Commentary:
;; 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 the following browsers,
;; some of them probably now obsolete:
;; Function Browser Earliest version
;; browse-url-mozilla Mozilla Don't know
;; browse-url-firefox Firefox Don't know (tried with 1.0.1)
;; browse-url-galeon Galeon Don't know
;; browse-url-epiphany Epiphany Don't know
;; browse-url-netscape Netscape 1.1b1
;; browse-url-mosaic XMosaic/mMosaic <= 2.4
;; browse-url-cci XMosaic 2.5
;; browse-url-w3 w3 0
;; browse-url-w3-gnudoit w3 remotely
;; browse-url-iximosaic IXI Mosaic ?
;; browse-url-lynx-* Lynx 0
;; browse-url-grail Grail 0.3b1
;; browse-url-mmm MMM ?
;; browse-url-generic arbitrary
;; browse-url-default-windows-browser MS-Windows browser
;; browse-url-default-macosx-browser Mac OS X browser
;; browse-url-gnome-moz GNOME interface to Mozilla
;; browse-url-kde KDE konqueror (kfm)
;; [A version of the Netscape browser is now free software
;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is
;; reasonable to have that as the default.]
;; Note that versions of Netscape before 1.1b1 did not have remote
;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>.
;; Browsers can cache Web pages so it may be necessary to tell them 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?
;; 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.
;; The `gnuserv' package that can be used to control it in another
;; Emacs process is available from
;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>.
;; 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://grail.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>.
;; Lynx is now distributed by the FSF. See also
;; <URL:http://lynx.browser.org/>.
;; Free graphical browsers that could be used by `browse-url-generic'
;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and
;; <URL:http://www.unlv.edu/chimera/>, Arena
;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya
;; <URL:ftp://ftp.w3.org/pub/amaya>. mMosaic
;; <URL:ftp://ftp.enst.fr/pub/mbone/mMosaic/>,
;; <URL:http://www.enst.fr/~dauphin/mMosaic/> (with development
;; support for Java applets and multicast) can be used like Mosaic by
;; setting `browse-url-mosaic-program' appropriately.
;; I [Denis Howe, not Dave Love] 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/%7Enelson/hhm-beta/>
;; See also hm--html-menus <URL:http://www.tnt.uni-hannover.de/%7Emuenkel/
;; software/own/hm--html-menus/>. For composing correct HTML see also
;; PSGML the general SGML structure editor package
;; <URL:ftp://ftp.lysator.liu.se/pub/sgml>; hm--html-menus can be used
;; with this.
;; This package generalises function html-previewer-process in Marc
;; Andreessen's html-mode (LCD modes/html-mode.el.Z). See also the
;; ffap.el package. The huge hyperbole package also contains similar
;; functions.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; 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
;; or, similarly but with the opportunity to edit the URL extracted from
;; the buffer, use:
;; M-x browse-url
;; 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
;; To display the current region in a web browser:
;; M-x browse-url-of-region 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'. Better, use
;; `M-x customize-group browse-url'.
;; 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-zr" 'browse-url-of-region)
;; (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
;; (lambda ()
;; (local-set-key "\C-c\C-zf" 'browse-url-of-dired-file)))
;; Browse URLs in mail messages under RMAIL by clicking mouse-2:
;; (add-hook 'rmail-mode-hook (lambda () ; rmail-mode startup
;; (define-key rmail-mode-map [mouse-2] 'browse-url-at-mouse)))
;; Alternatively, add `goto-address' to `rmail-show-message-hook'.
;; Gnus provides a standard feature to activate URLs in article
;; buffers for invocation of browse-url.
;; 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
;; (lambda ()
;; (add-hook 'local-write-file-hooks
;; (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.
;; To invoke different browsers for different URLs:
;; (setq browse-url-browser-function '(("^mailto:" . browse-url-mail)
;; ("." . browse-url-netscape)))
