Extension:Popups/pl

The Popups extension displays page previews − summaries of an article's content when the user hovers over a link to that article.

This is an initiative of the Design team, inspired by the popular Navigation popups gadget. Currently this feature is available as a Beta Feature on Wikimedia wikis. A description of how the extension functions and more information on its use on Wikimedia projects is available at Page Previews.

Content
The popups show an image (if one is available), a small text excerpt and the timestamp of the last edit.

Image
The image comes from the Extension:PageImages which returns the single most appropriate thumbnail associated with an article. It ignores maintenance templates, stubs, flag icons etc.

Tekst
The text comes from the Extension:TextExtracts from which a plain-text extract is requested (see that extension for exclusions). Two sentences are requested from the intro section and a limit is put through CSS that makes sure that text doesn't overflow from the card. This is done by applying a max-height on that element. This approach would provide the same visual solution regardless of the language's script. A major con is that the text stops abruptly and ellipses can't be added.

Show/hide timing
The timing of the show/hide can currently be adjusted via code, which should be added to your local Special:MyPage/common.js or global.js file :

Renderers
This extensions currently has only one renderer, that is for ordinary pages. New renderers for different kind of pages, or things like references can be easily added. One needs to create a new object with the following methods:


 * init
 * createPopup
 * getOffset
 * getClasses
 * processPopup

You can see details of these methods in ext.popups.renderer.article.js or this patch that adds a renderer for references.
