Module:Effective protection level/doc

This module provides a way to retrieve the group required to perform a given action on a page. It currently tests the following criteria:
 * The page being pending-changes protected: reviewer or autoconfirmed
 * The page being in the MediaWiki namespace: sysop
 * The page being a userspace .js or .css: sysop
 * The page being protected: sysop, templateeditor, or autoconfirmed
 * The page being used in a cascading-protected page: sysop
 * The page's title matching the titleblacklist: accountcreator or autoconfirmed
 * A file being moved: filemover
 * A page being moved or a file being uploaded: autoconfirmed
 * A non-Draft non-talk page being created: user
 * Anything else: *

Note that if a template-protected file is moved, both filemover and templateeditor are required, but this will return only templateeditor. This is not likely to be changed any time soon, since template protection currently shouldn't be used on files.

From other modules
To load this module:

The function accepts three parameters. The first is a frame (passing nil results in mw.getCurrentFrame being used). The second is a string containing the action to check, which must be one of "edit", "create", "move", "upload", or "autoreview". The third is optional, and can either be the name of the page to check, or a title returned from the mw.title functions. If the second parameter is omitted, the page being displayed is the one checked against. The return value is a string containing the name of the group required to perform the given action.

From wikitext
The parameters are the same as when it is called directly.
