=== The "page" parameter ===

For testing and demonstration purposes this template can take a parameter named '''page'''. Like this:

<pre>
{{category handler
| main = Category:Some cat
| talk = Category:Talk cat
| nocat = {{{nocat|}}}   <!--So "nocat=true/false" works-->
| page = User talk:Example
}}
</pre>

In the above code we on purpose left out the brackets around the category names so we see the output on the page. No matter on what kind of page the code above is used it will return this:

:{{category handler
| main = Category:Some cat
| talk = Category:Talk cat
| nocat = {{{nocat|}}}   <!--So "nocat=true/false" works-->
| page = User talk:Example
}}

The '''page''' parameter makes this template behave exactly as if on that page. Even the blacklist works. The pagename doesn't have to be an existing page.

If the '''page''' parameter is empty or undefined, the name of the current page determines the result.

You can make it so your template also understands the '''page''' parameter. That means you can test how your template will categorize on different pages, without having to actually edit those pages. Then do like this:

<pre>
{{category handler
| main = Category:Some cat
| talk = Category:Talk cat
| nocat = {{{nocat|}}}   <!--So "nocat=true/false" works-->
| page = {{{page|}}}   <!--For testing-->
}}
</pre>
