Redigerer Mal:Category handler/blacklist/dok (avsnitt)

=== Testing the blacklist ===

There are two ways you can test what this blacklist returns for a page:

You can put this template on the page you want to test, and see what output it produces. You can use edit preview, no need to save. Like this:

:<code><nowiki>+{{category handler/blacklist}}+</nowiki></code>

Which here on this page returns this:

:+{{category handler/blacklist}}+

The ++ used here is a simple way to make it visible when a template returns an empty string.
