Editing Template:Category handler/doc (section)

=== Blacklist ===

This template has a blacklist of the pages and page types where templates should not auto-categorize. Thus templates that use this meta-template will for instance not categorize on /archive pages and on the subpages of [[w:Wikipedia:Template messages]].

If you want a template to categorize on a blacklisted page, then feed "<code><nowiki>nocat = false</nowiki></code>" to the template when you place it on the page, thus skipping the blacklist check. Note that this template only categorizes if it has data for the namespace. For instance, if the basic syntax is used (see [[#Basic usage|basic usage]] above), then even if you set "<code>nocat = false</code>" the template will not categorize on a talk page, since it has no data for talk pages. But it has data for help space, so on a blacklisted help page it will categorize.

The blacklist is in the module [[Module:category handler/blacklist]].
