Interwiki Popups

Adds hover previews (via Extension:Popups) for interwiki links pointing to Wikipedia, on wikis where you can't install a custom PHP extension (e.g. Miraheze).

Popups exposes a mw.popups.register() function briefly, then deletes it| This script grabs a reference to it the instant it's created, before the deletion happens, and uses it to register a second preview type that only matches interwiki links.

Supported Interwikis

Currently, only en.wikipedia.org. Please submit a PR if you'd like to add support for more wikis.

Requirements

• Extension:Popups installed and enabled
• Ability to run custom Javascript, either through MediaWiki:Common.js or Extension:Gadgets
• JsDelivr and the target wiki allowed via CSP

Installation using Extension:Gadgets

1. Create MediaWiki:Gadget-interwiki-popups.js on your wiki, with this content:

   mw.loader.load( 'https://cdn.jsdelivr.net/gh/JJTech0130/interwiki-popups@main/interwiki_popups.js' );

2. Create MediaWiki:Gadget-interwiki-popups with a short description, e.g.:

   '''[https://github.com/JJTech0130/interwiki-popups Interwiki Popups]:''' Article previews when hovering over interwiki links to Wikipedia.
   

3. Add a line to MediaWiki:Gadgets-definition:

   * interwiki-popups[ResourceLoader|type=general]|interwiki-popups.js
   

4. Enable it for yourself under Special:Preferences -> Gadgets, and confirm it's working by hovering an interwiki link like [[wikipedia:Main Page]] on a content page. Check your browser console for:

   [interwiki-popups] registered via captured register()
   

5. Once you're happy with it, you can make it load for everyone by default by adding |default inside the brackets in step 3:

   * interwiki-popups[ResourceLoader|type=general|default]|interwiki-popups.js
   

Installation using MediaWiki:Common.js or User:YourUsername/common.js

Add the following line:

mw.loader.load( 'https://cdn.jsdelivr.net/gh/JJTech0130/interwiki-popups@main/interwiki_popups.js' );
