MediaWiki:Gadget-ZkontrolovanoUcitelem.js

/*!
 * This script adds a "Your signature" button to the "Insert" menu in VisualEditor.
 *
 * The button is only available in non-content namespaces and, you guessed it, inserts a signature
 * with time for the current user into the page. The signature always reflects current time and
 * can not be modified.
 *
 * Existing signatures on the page are not parsed, like in wikitext.
 *
 * To enable, add the following snippet to your common.js page (on any wiki):
 *   mw.loader.load('//meta.wikimedia.org/w/index.php?title=User:Matma_Rex/visualeditor-signature.js&action=raw&ctype=text/javascript');
 *
 * Author: Bartosz Dziewoński ([[User:Matma Rex]])
