Install mediawiki.el from el-get or ELPA.

If you are using emacs-24, you could do the following: Edit your .emacs file like this:

(require 'package)
(add-to-list 'package-archives '("melpa" . "") t)

Then, either use the menu Options->Manage Emacs Packages or type M-X package-list-packages

  • search mediawiki and click on it

... almost done.

Site requirements

The MediaWiki site that you wish to edit must have its API enabled:



M-x load-library RET mediawiki RET
Load the library
M-x customize-variable RET mediawiki-site-alist
Configure as follows and save your settings
Site Name: WikEmacs
Username: InCognito
Password: s!cr!t
First Page: Main Page
You can provide "Username" and "Password" in your .authinfo file, located in you home directory. For a MediaWiki, .authinfo lines have the form:
machine login myUsername password myPassword

Alternatively you can add this snippet of Emacs Lisp code to your .emacs:

(require 'mediawiki)

(setq mediawiki-site-alist '(("Wikipedia" " "" "" "Main Page") ; put your user name and password if not using .authinfo
                             ("WikEmacs" "" "" "" "Main Page")))

;; Emacs users care more for WikEmacs than Wikipedia :-). 
;; In any case, do not forget the slash at the end of the URL.
(setq mediawiki-site-default "WikEmacs")

You can naturally add more MediaWiki sites to the mediawiki-site-alist variable.


M-x mediawiki-site
Choose a site (say "WikEmacs") for the current session.
[C-c C-o] (or M-x mediawiki-open)
Open a page. To edit the main page, type "Main Page". Make your edits.
[C-x C-s] (or M-x mediawiki-save)
Submit your modifications.
[C-c C-c] (or M-x mediawiki-save-and-bury)
Submit modifications and bury the buffer.

Helpful Keybindings

[C-return] (or M-x mediawiki-open-page-at-point)
Follow or browse to a WikiLink.
[M-g] (or M-x mediawiki-reload)
Reload a page
[Tab] (or M-x mediawiki-mediawiki-goto-next-link)
Get to next link


Word Wrap

Mediawiki sites are generally unfilled: do not add hard line breaks within a paragraph. There are various ways to wrap lines visually while you edit. For example in Emacs 24 you may want to enable Visual Line mode with a mode hook:

(setq mediawiki-mode-hook (lambda ()
                            (visual-line-mode 1)))

Edit or Create a page in a web browser

Right now Mediawiki.el fails silently whenever the site asks for number challenge (spam protection). The following snippet allows you to edit/create a page in a web browser

(defun yyr-mediawiki-browser-edit/create-page (page &optional site)
  "Edit a page in browser, asks for page name (sitename also if needed)"
  (interactive "sPage name (words): ")
  (let* ((site (mediawiki-prompt-for-site))
         (url (mediawiki-site-extract site 1))
         (index "index.php?title=")
         (et "&action=edit"))
    (funcall 'browse-url
             (message "%s%s%s%s"
                      url index (mediawiki-translate-pagename page) et))))

Call yyr-mediawiki-browser-edit/create-page

Key binding to open current editing file in web browser

Bind mediawiki-browse to some key chord. The following uses [C-c o]

(define-key mediawiki-mode-map (kbd "C-c o") 'mediawiki-browse)

Known Bugs

  • Version 2.2.2 works fine on GNU Emacs (i386-mingw-nt5.1.2600) when there is no challenge (e.g. arithmetic problem). But when external links are added, so there is a challenge, mediawiki doesn't alert the user or show the arithmetic problem. The only evidence of failure is that the page is never updated.
