Elisp: View URL in Web Browser: browse-url

In emacs, there's a function browse-url . It sends a URL to a web browser.

Call it to view the URL under cursor in browser.

Use it in emacs lisp code like this:

( require 'browse-url) (browse-url "http://google.com/" )

browse-url is defined in browse-url.el .

browse-url-of-buffer → sends the current (local HTML) file in browser.

For example use, see: Emacs: Lookup Google, Dictionary, Documentation.

[see Emacs: Set Default Browser]

Launching Browser by Shell Command

There's also browse-url-firefox . But i recall, under Microsoft Windows, there's some problems.

You can also launch a browser by making a shell call. For example:

( defun my-browse-url-of-buffer-with-firefox () "Same as `browse-url-of-buffer' but using Firefox. You need Firefox's path in the path environment variable within emacs. e.g. (setenv \"PATH\" (concat \"C:/Program Files (x86)/Mozilla Firefox/\" \";\" (getenv \"PATH\") ) ) On Mac OS X, you don't need to. This command makes this shell call: 「open -a Firefox.app http://example.com/」" ( interactive ) ( cond (( string-equal system-type "windows-nt" ) (shell-command ( concat "firefox file://" buffer-file-name ))) (( string-equal system-type "gnu/linux" ) (shell-command ( concat "firefox file://" buffer-file-name ))) (( string-equal system-type "darwin" ) (shell-command ( concat "open -a Firefox.app file://" buffer-file-name )))))

You have to make sure that the path of firefox. For example: C:/Program Files (x86)/Mozilla Firefox/ is in emacs's (getenv PATH) result. Here's a example of how to add it:

( setenv "PATH" ( concat "C:/Program Files (x86)/Mozilla Firefox/" ";" ( getenv "PATH" )))

You might want to give it a key. [see Emacs: How to Define Keys]
