Help:Categories/ru

Categories, a software feature of MediaWiki, provide automatic indexes that are useful as tables of contents.

You can categorize pages and files by adding one or more Category tags to the content text. These tags create links at the bottom of the page that take you to the list of all pages in that category, which makes it easy to browse related articles.

Summary
Each of the pages in the Category namespace represents a so-called category, a grouping of related pages, and contains an index for the pages of its category. For example, this page belongs to "Category:Help". If you open the "Category:Help" page, you will see a link to this page there.

When a page belongs to one or more categories, these categories appear at the bottom of the page (or in the upper-right corner, depending on the skin being used).

The category pages themselves contain 2 parts:


 * at their beginning, an optional part may contain text that can be edited, like any other page,
 * at their end, an ever present, automatically generated, alphabetical list of all pages in that category, in the form of links. (In fact, in ASCII order. See Help:Special page).

To assign a category to a page, simply add the link " Category:Category name" to the page's wikitext. The usual place to add it is at the bottom of the page.

To link a category page within a page as a normal wiki link (without adding the page to the category), prefix the link name with a colon. For example: :Category:Not in this category

New categories can be created before assigning any page to it, in the same way as any other regular page.

Individual wikis may have their own top-level categories, such as Category:Contents in Wikipedia.

For a complete list of all categories which have at least one page, see Special:Categories.

For a complete list of all created/edited categories, including the ones that don't have any page, see Special:Allpages/Category: (note the colon at the end).

Включение страницы в категорию
Чтобы включить в категорию страницу или загруженный файл, просто войдите в режим редактирования и поместите следующий код в самый низ редактируемой страницы (где ИМЯ — это имя категории, в которую будет добавлена редактируемая страница):



Данным способом страницу можно добавить в любое количество категорий, и она будет отображаться в них всех. Теги «   » могут быть добавлены в любом месте текста при его редактировании, но для удобства других редакторов их добавляют обычно в самом низу страницы.

On a categorised page, categories are displayed in the Categories: box strictly in the order they appear in the wikitext.

If $wgUseCategoryBrowser is set to true, under the first list each category is listed again, breadcrumb-style, with all its parent categories, sorted alphabetically. (At least in MediaWiki 1.18.2) if a category is a subcategory of more than one parent, both hierarchies will be listed, but the tagged category will be stripped off all but one of these. This creates the potential for what appear to be duplicate entries if a category with multiple parents and one of its parents are both tagged on a page. For example suppose Maryanne is a subcategory of both Mary and Anne. If a page tags categories Maryanne and Anne then the Category breadcrumbs will show

Anne Anne Mary -> Maryanne

"Anne" appears to be duplicated, but what is meant is

Anne Anne -> Maryanne Mary -> Maryanne

This is probably a bug, and has been reported in Bug 33614.

Ключ сортировки
By default, a page is sorted within a category under the first letter of its name — without the namespace. Also, MediaWiki groups accented characters separately from their unaccented version, so pages starting by À, Á, Ä, will be listed under separate headings, instead of under heading A. (If you have shell access, these defaults can be changed using $wgCategoryCollation.)

A sort key specifies under which letter heading, and where in the category list, the page will appear. You can add a sort key by placing it inside the tag after a pipe character. For example, the tag below will add the page under heading "S".

Sort

Sort keys are case-sensitive, and spaces and other characters are also valid. The order of the sections within a category follows the Unicode sort order. The sort key does not change the page title displayed in the category.

See Help:Sorting for further information on category sorting.

Creating a category page
Categories exist even if their page has not been created, but these categories are isolated from others and serve little purpose for organization or navigation.

A category is created by creating a page in the Category: namespace. A category page can be created the same way as other wiki pages (see Help:Starting a new page); just add " " before the page title.

Чтобы избежать дополнительной работы, попробуйте перед созданием новых категорий, поискать в своей вики уже существующие. Список всех категорий доступен через команду в «», находящуюся в разделе «» бокового меню.

Unlike other wiki pages, it is not possible to rename (move) a category. It is necessary to create a new category and change the     tag on every page. The new category will not have the older category's page history, which is undesirable if there are many revisions.

Managing the category hierarchy
Categories may belong to other categories in a hierarchy. Since category pages are much like any other page, a     tag may be added to the bottom of a category page.

It is a good idea to organize all categories into a hierarchy with a single top level category. The category structure can take the form of a tree with separate branches, but more often will have a graph structure. Generally, there should be a contiguous chain of parent-child links between each category and the top level category.

Скрытые категории
The categories that a page is in are normally listed at the bottom of the page. In Mediawiki 1.13+, a category can be hidden from this list by adding the magic word " " to the category page. Hidden categories are not hidden from category pages.

Users can choose to see hidden categories in a separate "" list, by checking "" in the "" section of Special:Preferences.

Скрытые категории автоматически добавляются в Category: (настраивается через MediaWiki:Hidden-category-category).

Ссылки на категории
Чтобы создать ссылку на категорию, используют ведущее двоеточие перед названием категории. (Ссылка без такого двоеточия просто добавит текущую страницу в эту категорию.) Чтобы изменить текст ссылки, напишите текст внутри ссылки после разделителя в виде вертикальной черты («пайпа»).


 * &rarr;    :Help

To change the link text, write the text inside the link tag after a pipe:


 * &rarr; Help category

Redirect pages that redirect to categories must also use the colon, otherwise they will be added to the category instead of redirecting.

Redirecting a category
Like normal wiki pages, category pages can be redirected to other normal or category pages. However, this is not recommended, as pages categorised in redirected categories do not get categorised in the target category (bugzilla:3311). Some Wikimedia sites use a "category redirect" template to mark redirected categories, allowing manual or automated cleanup of pages categorised there.

Tracking categories
Certain syntax issues, such as a broken image link, or too many expensive parser functions, can cause a page to be added to a tracking category. See Help:Tracking categories for details.
