=== The "page" parameter ===

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

<source lang="lua">
p = {}
local categoryHandler = require( 'Module:Category handler' ).main
 
function p.main( frame )
    local category = categoryHandler{
        main = 'Category:Some cat',
        talk = 'Category:Talk cat',
        nocat = frame.args.nocat, -- So "nocat=true/false" works
        page = 'User talk:Example'
    }
    return category
end
 
return p
</source>

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:

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

The '''page''' parameter makes this module 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 module 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:

<source lang="lua">
p = {}
local categoryHandler = require( 'Module:Category handler' ).main

function p.main( frame )
    local category = categoryHandler{
        main = 'Category:Some cat',
        talk = 'Category:Talk cat',
        nocat = frame.args.nocat, -- So "nocat=true/false" works
        page = frame.args.page -- For testing
    }
    return category
end

return p
</source>
