Редактирование: Модуль:Category handler/doc (раздел)

=== Categories and text ===

Besides from categories, you can feed anything else to this module, for instance some text. Like this:

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

function p.main( frame )
    local result = 'This is a module used on talk pages.'
    local category = categoryHandler{
        talk = '[[Category:Somecat]]',
        other = '<p class="error">This module should only be used on talk pages.</p>',
        nocat = frame.args.nocat -- So "nocat=true/false" works
    }
    category = category or '' -- Check that we don't have a nil value for the category variable.
    return result .. category
end

return p
</source>

When the module code above is used on anything other than a talk page, it will look like this:

:This is a module used on talk pages.{{#invoke:category handler|main
| talk = [[Category:Somecat]]
| other = <p class="error">This module should only be used on talk pages.</p>
| nocat = {{{nocat|}}} <!--So "nocat=true/false" works-->
}}

That text will not show on blacklisted pages, so don't use this method to show any important information. Feeding "<code>nocat = 'true'</code>" to the template hides the text, just as it suppresses any categories.
