Editing Module:ParameterCount/doc (section)

This module counts the number of parameters that are passed to a template. For example, you might put the code <code><nowiki>{{#invoke:ParameterCount|all}}</nowiki></code> inside the <code><nowiki>{{my template}}</nowiki></code> template. If you then use <code><nowiki>{{my template}}</nowiki></code> like this:

<pre>
{{my template
| one
| two
| three
}}
</pre>

Then the <code><nowiki>{{#invoke:ParameterCount|all}}</nowiki></code> code inside the template will give the result <code>3</code>.

This module can be configured to count all parameters, or specific parameters defined by a template author. This module is only useful in templates. It should not be used on non-template pages.

The module has two functions available, <code>all</code> and <code>main</code>.
