Extension:Popups/es

The Popups extension displays "hovercards" − popups with summaries of article contents when the user hovers over an article link.

This is an initiative of the Design team, to move popular Gadgets into Beta Features. Mockups and more information available at Hovercards.

Dependencias
This extension has a hard dependency on Extension:TextExtracts and Extension:PageImages. There is also an optional dependency on Beta Features (without BetaFeatures, it loads for all users) and Extension:EventLogging (for logging).

 * Enable the beta feature

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

Imagen
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.

Texto
The text comes from the Extension:TextExtracts from which a plain-text extract is requested (see that extension for exclusions). 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.
