=== Categories and text === Besides from categories, you can feed anything else to this module, for instance some text. Like this: <syntaxhighlight 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 </syntaxhighlight> 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.
