How to: Handle category pages easily

From xoa

Categories get created automatically, just by doing this at the bottom of a page:

[[Category:Perl]]

Your page is now part of [[:Category:Perl]]. If there's not a page for [[Category:Perl]], you can create it. But don't do it yet.

First, go make a page called [[Perl]]. Put in a little discussion of what Perl is.

Then, on the [[Category:Perl]] page, transclude the main topic page, like this:

{{:Perl}}

That's it. Your category page will now slurp up the "real" page, and you'll have the same content at both [[Perl]] and [[Category:Perl]], except that the latter shows categorized pages below it, of course.

Here's how it looks here on xoa:

• [[Perl]]: Perl
• [[Category:Perl]]: Category:Perl
