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 JavaScript or CSS subpage in userspace: 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: templateeditor 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.

Usage
Warning: This module will use up to 4 expensive parser function calls each time it is ran. It should only be used if the exact effective protection level is necessary. Otherwise, consider using title.protectionLevels instead.

From other modules
To load this module:

The function accepts two parameters. The first is a string containing the action to check, which must be one of "edit", "create", "move", "upload", or "autoreview". The second 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.
