Help:Gadgets

Gadgets is an extension that allows users to pick JavaScript or CSS based "gadgets" that other community users provide. The scripts will be available for users to enable or disable in their preferences under a tab labeled "Gadgets".

They're designed using JavaScript and/or CSS snippets located on pages in the MediaWiki namespace. Each gadget is added by adding a new entry to MediaWiki:Gadgets-definition, providing a name and description for the gadget, and a list of the JS and CSS snippets that it uses (see the Usage section below).

Gadgets use the same principle as [ MediaWiki:Wikia.js], [ MediaWiki:Common.css], etc. because they allow scripting or styling over the entire site. Since Gadgets function in this manner (the list that enables them as well as the actual JS and CSS pages), it requires being a wiki admin to manage these, just like the sitewide JS or CSS.

Usage
First you need to add a script or style to a page in the MediaWiki namespace (e.g. [ MediaWiki:Gadget-popups.css]). Then you add that page to [ MediaWiki:Gadgets-definition] as shown here:

Example-gadgets
The first field is the gadget's internal name, and may only contain letters and numbers in order to function correctly. If the internal name is Navigation_popups, the corresponding MediaWiki namespace page will be [ MediaWiki:Gadget-Navigation popups]. This page allows you to define a description text which will be displayed on the Gadgets section of your preferences.
 * Navigation_popups|popups.js|popups.css
 * contribsrange|contribsrange.js

The second and subsequent fields define the pages that make up the code. In the above example, popups.js and popups.css would be [ MediaWiki:Gadget-popups.js] and [ MediaWiki:Gadget-popups.css] respectively. Like other sitewide pages, Gadgets may only be written using JS and CSS pages.

These defined pages will allow the gadget to appear in the "Gadgets" section of everyone's preferences, so users can choose which gadgets fit their community's needs. An overview of added gadgets can be found on [ Special:Gadgets], along with links to the respective pages that define them, which allows for better control over the wikis's gadgets.

The [ Special:Gadgets] page allows quick overview and easy management of all your gadgets interface with easy linking to every special page that controls all of your gadgets functionality and interface. The headings that appear in your preferences may also be redefined here.

Please note that all Gadget MediaWiki namespace pages must be prefixed with Gadget-, the only exception is where you define them in [ MediaWiki:Gadgets-definition] as displayed in the above example.
