MediaWiki:Gadget-morebits.js

// /** * A library full of lots of goodness for user scripts on MediaWiki wikis, including Wikipedia. * * The highlights include: * - {@link Morebits.wiki.api} - make calls to the MediaWiki API * - {@link Morebits.wiki.page} - modify pages on the wiki (edit, revert, delete, etc.) * - {@link Morebits.date} - enhanced date object processing, sort of a light moment.js * - {@link Morebits.quickForm} - generate quick HTML forms on the fly * - {@link Morebits.simpleWindow} - a wrapper for jQuery UI Dialog with a custom look and extra features * - {@link Morebits.status} - a rough-and-ready status message displayer, used by the Morebits.wiki classes * - {@link Morebits.wikitext} - utilities for dealing with wikitext * - {@link Morebits.string} - utilities for manipulating strings * - {@link Morebits.array} - utilities for manipulating arrays * - {@link Morebits.ip} - utilities to help process IP addresses * * Dependencies: * - The whole thing relies on jQuery. But most wikis should provide this by default. * - {@link Morebits.quickForm}, {@link Morebits.simpleWindow}, and {@link Morebits.status} rely on the "morebits.css" file for their styling. * - {@link Morebits.simpleWindow} and {@link Morebits.quickForm} tooltips rely on jQuery UI Dialog (from ResourceLoader module name 'jquery.ui'). * - To create a gadget based on morebits.js, use this syntax in MediaWiki:Gadgets-definition: *    - `*GadgetName[ResourceLoader|dependencies=mediawiki.user,mediawiki.util,mediawiki.Title,jquery.ui]|morebits.js|morebits.css|GadgetName.js` * - Alternatively, you can configure morebits.js as a hidden gadget in MediaWiki:Gadgets-definition: *    - `*morebits[ResourceLoader|dependencies=mediawiki.user,mediawiki.util,mediawiki.Title,jquery.ui|hidden]|morebits.js|morebits.css` *    and then load ext.gadget.morebits as one of the dependencies for the new gadget. * * All the stuff here works on all browsers for which MediaWiki provides JavaScript support. * * This library is maintained by the maintainers of Twinkle. * For queries, suggestions, help, etc., head to [Wikipedia talk:Twinkle on English Wikipedia](http://en.wikipedia.org/wiki/WT:TW). * The latest development source is available at {@link https://github.com/wikimedia-gadgets/twinkle/blob/master/morebits.js|GitHub}. * * @namespace Morebits */
