Extension:Popups/ru

Расширение Popups отображает предварительный просмотр страниц и ссылок при наведении курсора на ссылку на статью или, соответственно, на ссылку. Первый состоит из резюме содержания статьи, второй показывает полное содержание ссылки.

Это инициатива команды дизайнеров, вдохновленных популярным гаджетом Навигационные окошки. В настоящее время эта функция доступна во всех Википедиях по умолчанию для вышедших из системы пользователей. Описание функций расширения и дополнительную информацию о его использовании в проектах Викимедиа доступно в Page Previews.

The Reference Previews feature was added eventually and aims to fulfill a wish from the German-speaking community's Technical Wishlist. A more detailed description and more information on its use is available at.

Page previews API
Every project is different, and what displays in your previews is highly dependent on the content inside your wiki.

Extension:Popups has been optimised to work with Wikipedia-like content (e.g. wikitext). If your wiki is using a different kind of content handler (for example as is the case for Wikibase) it will need to provide its own API.

The API can be written in any language, but the response of the API must match the spec defined here:

https://www.mediawiki.org/wiki/Specs/Summary/1.2.0

Defining new APIs is out of scope for the Popups extension.

Once defined, you can configure page previews to point to your API using  configuration option.

Page previews content
Всплывающие окна предварительного просмотра страницы показывают изображение (если оно доступно) и небольшой фрагмент текста.

Изображение
Изображение формируются при помощи, которое возвращает одну наиболее подходящую миниатюру, связанную со статьей. Он игнорирует шаблоны обслуживания, незавершённые статьи и т.д.

Текст
The page previews can be configured with any compatible API that is compatible with the Page content service summary endpoint using. For third parties we encourage using the Page Content Service to enjoy using Popups with your local wiki.

You can also use the extension. This extension has various caveats and we do not actively support use of this API.

Reference previews content
The content in the reference preview popups is taken directly from the reference section on the page itself. No external services are involved here. If the content exceeds the popup size scrollbars are shown so everything can be looked at.

Reference types
The reference types displayed are set by using specific CSS-classes on the -tag that can be used to encapsulate the content of a reference e.g.. Currently there are four different types supported:,  ,  ,. Apart from that there is always a generic fallback if neither the cite tag was found nor an appropriate class was used.

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:



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

Known problems

 * Users of the Translate extension should note that Page Previews requests previews in the content language of the page. If the preview contains a complete translatable block, then it will be translated. If, however, the preview contains an incomplete translateable block – because a sentence is cut off, say – then it isn't translated and will be displayed in the content language of the page. If you are observing this behavior, then you should consider marking up individual sentences in your lead section.


 * T167852 is for a technical audience but has more information on the underlying problem.


 * Longer math formulas cutting off in preview - long math or chemical formulas (formulas wider than the preview width) display as truncated in previews. We were not able to add a gradient in order to indicate that the formula is continued on the article itself.

Why can't I copy and paste text from a preview?
At time of writing, the cons of doing so outweigh the pros. Essentially it boils down to decreasing the touch area to read the article in full. Once Page Previews is deployed on English and German Wikipedia, feel free to reopen this task and reignite the discussion, but right now we have no plans.

How can I change the image that I see on preview?
See Extension:PageImages#Image choice.

How can I remove content from a page preview?
Any element marked with the  class will be stripped from the summary.

Where do summaries come from?
These are provided by the Summary REST API.

Why are parenthetical stripped?
There's a good discussion going on in T91344 in Phabricator. If you have any views on this or see any problems relating to this, please let us know there.

Why don't I see Popups outside of content namespaces?
Popups appear on links to pages in content namespaces only. This is a limitation of Popups; TextExtracts are available from other namespaces. You may work around this by appending more namespaces into.
