Module:Effective protection expiry

This module provides a way to retrieve the expiry of a restriction over a given action on a page.

Usage

This module will use up to 1 expensive parser function call each time it is ran. It will not use any if Module:Effective protection level was already called.

From other modules

To load this module:

local effectiveProtectionExpiry = require('Module:Effective protection expiry')._main

The function accepts two parameters. The first is a string containing the action to check, which must be one of "edit", "create", "move", or "upload". 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 either a date string in YY-MM-DDThh:mm:ss format, or one of the following strings:

• infinity - for pages protected indefinitely
• unknown - for pages which are not protected or where the expiry is unknown

Note that if the page is not protected for the requested action, this will return 'infinity'. You need to check separately with Module:Effective protection level.

From wikitext

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

{{#invoke:Effective protection expiry|action|title}}
