Hi, interested in scripting? We need help, so do not hesitate to ask what you can do. We recommend start testing in your user-namespace (new users see basic instructions here).

We have a JavaScript styleguide, but it is a guide, not a policy. Nevertheless, consider reading the MediaWiki manual.

A list of currently available scripts can be found at Category:User scripts.

TO-DO

• Clarify the copyright situation of user-scripts.
• standardize scripts’ i18n methods → Gadgets 2.0 (mw.msg; example; explanation)
• Search & Detecting security vulnerable
• (urgent) Fix script affected by changes in the default continuation

To create

These are just suggestions. Feel free to comment in the talk-section.

• A script to get a formatted list of uploads, category-members, …
• A plugin to install scripts loaded with &withJS= – URL parameter to the user’s common or skin.js
• A script-installer which is invokable by a template (URL-params maybe) with a step-by-step wizard (done for gadgets → Template:ActivateGadget)
• A global-user-page and settings wizard allowing to create and update the userpage on several wikis.  Done
• A slideshow-framework using templates and script like Image Annotator or {{ImageStack}} with customizable caption-boxes, slide-effects, drag&slide, preview thumb-bar, …
• Integrate code for VIC and FPC nomination in MediaWiki:Gadget-QInominator.js.
• An autotranslate-template creation wizard  Done, see AutotranslateHelper — 0x010C ^~talk~ 09:40, 4 April 2017 (UTC)
• Refractor MediaWiki:Gadget-LanguageSelect.js: Multiple language-preferences, showing a (+) like HotCat allowing to add a translation (create an input on-the-fly) to push i18n forward
• Script to show 1-3 file examples in parent categories from their child categories (Special:Permalink/84246834#Galleries in Categories)
• Rewrite DerivativeFX as a JavaScript application m:WMDE Technical Wishes/Move files to Commons ^phab:T190716
• A tool to visually explore Flickr-Images from streams/sets/… before uploading and allowing to unselect some of them by given criteria
• A script to allow admins to close undeletion requests like closing deletion requests with MediaWiki:Gadget-DelReqHandler.js (maybe inside delreqhandler)  Done here by Perhelion
• A tool similar to Help:QuickDelete but instead of adding deletion templates you can choose to add {{Opaque}}, {{Convert to SVG}} or {{BadJPEG}}.

Scripts without il8n

• Category:User scripts needing internationalisation

Other

• MediaWiki:Gadget-ChooseResolution.js, MediaWiki:Gadget-dictionaryLookupHover.js not installed as a gadget
• MediaWiki:Gadget-Tag.js – ? not installed

Under construction

• Improve: Gallery-like mass-changing script Help:VisualFileChange.js (former User:Rillke/AjaxMassDelete.js)
• Improve: Gallery of uploads Commons:Gallery tool (wrapper for MediaWiki:JSONListUploads.js)
• Improve: licensereviewer.js (switch to API, ease the process)
• Waiting for clearance: Common SVG Checker MediaWiki:CommonsSvgChecker.js and Commons:Commons SVG Checker as UI (former Commons:SVG Check)

Testing

You can test any script by running it from your console or put the code in a Special:MyPage/test.js and hit “preview”.

• jsfiddle.net – Edit CSS, JavaScript, HTML and run it (big sandbox)
• Testing with different IE versions (Windows) (IETester: For slow machines) (Expression Web SuperPreview: For mordern machines)
• &withJS functionality: Commons has per-page JavaScript functionality, via this code being included in MediaWiki:Common.js. Try a random image file with MediaWiki:VisualFileChange.js.
• Testing the API

Validating and styling

• Commons:User scripts/reports
• Use MediaWiki:Gadgetprototype.js for new gadgets.
• ESLint – JavaScript Code Quality Tool (former jshint)
• jslint – another JavaScript Code Quality Tool
• jsbeautifier – Indenting and formatting your script – also on Commons:
• Commons Beautifier: escape unsafe characters and beautify the source code
• compactor- or just search yourself

Tools

• {{Scriptuse}}

Troubleshooting

• Commons Diagnostic: Let affected users make the test
• &debug=true – URL parameter to get un-minified code
• Debug AJAX requests (using mockjax) GitHub doc
