Template:Cat in use

Template documentation[view] [edit] [history] [purge]

This template checks whether a category is 'in use', checking various combinations of whether the category exists (is not a redlink) and is populated (has pages in it).

Usage

• {{cat in use| Wikipedia }} → 0
• {{cat in use| Avpoaihaw }} → 0

The second parameter can be used to indicate the comparison performed:

• or returns "1" (true) if the category exists or has members (default);
• and returns "1" (true) if the category exists and has members;
• xor returns "1" (true) if the category exists but is empty, or if the category does not exist but has members.
