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 say what kind of comparison is done:

  • or – returns true if the category exists or has members
  • and – true if the category exists and has members
  • xor – true if the category exists but is empty, or if the category does not exist but has members (slightly weird, admittedly :D)
