This is a documentation subpage for Template:Resolve category redirect. It may contain usage information, categories and other content that is not part of the original template page.

This template is used in MediaWiki:Babel-category-override, and on approximately 744,000 pages, or roughly 1% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.

This template uses Lua: Module:Resolve category redirect (sandbox) Module:Template redirect regex (sandbox)

Resolves a soft category redirect.

It takes one parameter, which is the name of a category. It returns that category name, unless the category exists and is a ((category redirect)) ... when it returns the name of the redirect target.

Usage

((Resolve category redirect|categoryname))

Examples

Category exists and is not redirected

Category:1970s

• ((Resolve category redirect|1970s)) → 1970s
• ((Resolve category redirect|Category:1970s)) → Category:1970s

Category exists and is a soft redirect

Category:Mosques completed in the 19th century

• ((Resolve category redirect|Mosques completed in the 19th century)) → 19th-century mosques
• ((Resolve category redirect|Category:Mosques completed in the 19th century)) → 19th-century mosques

Category exists and is a soft redirect

Category:Organisations

• ((Resolve category redirect|Organisations)) → Organizations
• ((Resolve category redirect|Category:Organisations)) → Organizations

Non-existent category

Category:Colourless green things

• ((Resolve category redirect|Colourless green things)) → Colourless green things
• ((Resolve category redirect|Category:Colourless green things)) → Category:Colourless green things

Templates

Do not use templates in the target name.

((Resolve category redirect)) cannot expand any templates in the target name, and the { character caused crashes (as did } and !). So it does not attempt to resolve any redirect where the target includes those characters.

Example

• Category:1781 in Mexico‎ contained ((category redirect|((title year)) in New Spain)) which cannot be resolved. To be safe, ((Resolve category redirect|1781 in Mexico‎)) simply returned 1781 in Mexico‎.
  The above example has since been changed to ((category redirect|1781 in New Spain)), which can be resolved.

Avoiding deletion of the redirected page

If the parameter |keep=yes is included in the category redirect, this hides a speedy deletion button that is otherwise displayed to administrators.

It is helpful to also add ((R from category navigation)) to indicate that the redirect is required for navigation between category pages. See that template page for full syntax.
