// /** * morebits.js * =========== * A library full of lots of goodness for user scripts on MediaWiki wikis, including Wikipedia. * * The highlights include: *  - Morebits.quickForm class - generates quick HTML forms on the fly *  - Morebits.wiki.api class - makes calls to the MediaWiki API *  - Morebits.wiki.page class - modifies pages on the wiki (edit, revert, delete, etc.) *  - Morebits.wikitext class - contains some utilities for dealing with wikitext *  - Morebits.status class - a rough-and-ready status message displayer, used by the Morebits.wiki classes *  - Morebits.simpleWindow class - a wrapper for jQuery UI Dialog with a custom look and extra features * * Dependencies: *  - The whole thing relies on jQuery. But most wikis should provide this by default. *  - Morebits.quickForm, Morebits.simpleWindow, and Morebits.status rely on the "morebits.css" file for their styling. *  - Morebits.simpleWindow relies on jquery UI Dialog (ResourceLoader module name 'jquery.ui.dialog'). *  - Morebits.quickForm tooltips rely on Tipsy (ResourceLoader module name 'jquery.tipsy'). *    For external installations, Tipsy is available at. *  - To create a gadget based on morebits.js, use this syntax in MediaWiki:Gadgets-definition: *      * GadgetName[ResourceLoader|dependencies=mediawiki.user,mediawiki.util,jquery.ui.dialog,jquery.tipsy]|morebits.js|morebits.css|GadgetName.js * * Most of the stuff here doesn't work on IE < 9. It is your script's responsibility to enforce this. * * This library is maintained by the maintainers of Twinkle. * For queries, suggestions, help, etc., head to Wikipedia talk:Twinkle on English Wikipedia. * The latest development source is available at. */
