Editing Module:Category handler/doc (section)

=== When not to use this module ===

For cases where a module only needs to categorise in one of the namespaces main (articles), file (images) or category, then using this module is overkill. Instead, you can simply get a title object using [[mw:Extension:Scribunto/Lua reference manual#mw.title.getCurrentTitle|mw.title.getCurrentTitle]] and check the <code>nsText</code> field. For example:
<syntaxhighlight lang="lua">
local title = mw.title.getCurrentTitle()
if title.nsText == 'File' then
    -- do something
end
</syntaxhighlight>
However, if your module needs to categorize in any other namespace, then we recommend you use this module, since it provides proper category suppression and makes it easy to select how to categorize in the different namespaces.
