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-of-buffer → sends the current (local HTML) file in browser.
For example use, see: Emacs: Lookup Google, Dictionary, Documentation.
Launching Browser by Shell Command
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") ; Windows (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") ; Mac (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:
;; set env var named “path” by appending a new path (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]
