Editing Template:Yesno/doc

This template evaluates any input and produces a normalized <samp>yes</samp> or nil output, based on the content of the input and several configurable options. It is not meant for use directly in articles, but for making templates.

== In a nutshell ==
If the input the template receives is (not case sensitive) "no", "n", "false", "off", "0", is only whitespace, or is entirely missing; then the template returns an empty string. If any other value is received, then the template returns "yes".

This is useful for creating opt-in parameters in templates. For example, a nocat parameter:

<code><nowiki>{{#if: {{yesno| {{{nocat|}}} }} ||[[Category:Your category here]]}}</nowiki></code>

In this example, the template adds the page to the category, but if the user does not want that then they can set the parameter <code>nocat=yes</code>, <code>nocat=y</code>, etc.

This is a basic use case for this template. What the template outputs can be changed. For more complex usage, read [[wp:Template:Yesno|Wikipedia's documentation]].
