This is the {{category handler/blacklist}} sub-template.
Do not use this template directly, use {{category handler}} instead. This template is called from {{category handler}}, see user documentation there.
But if you came here to see or update the category suppression blacklist, then you are in the right place.
Updating the blacklist
[Bearbeiten]This template contains a blacklist of the pages and page types where templates should not auto-categorise. This blacklist is used by {{category handler}} to decide when not to categorise. To update the blacklist, edit this template.
This template uses {{if pagename}} to do the pagename-detection, thus see {{if pagename}} for the syntax to use for the blacklist rules.
When this template is placed on a page that should not categorise, then it should return "hide". And when placed on any other page it should return an empty string.
Testing the blacklist
[Bearbeiten]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:
+{{category handler/blacklist}}+
Which here on this page returns this:
- ++
The ++ used here is a simple way to make it visible when a template returns an empty string.
Or you can feed the pagename you want to test to this template. Then you can do all the testing for instance on the /testcases subpage of this template. Like this:
+{{category handler/blacklist| page = User:Example }}++{{category handler/blacklist| page = User:Example/Archive 5}}+
Which returns this:
- ++
- +hide+
Technical details
[Bearbeiten]Currently this template is only called from {{category handler}}, and indirectly from all templates that use {{category handler}}. But in the future this template might also be directly called from other templates similar to {{category handler}}. This means we can update the category suppression blacklist in one place.
