Module:If preview/doc

This module implements if preview and preview warning. It helps templates/modules determine if they are being previewed.

Prefer implementing the template versions in other templates.

In a module to use the &#x3c;code&#x3e;main&#x3c;/code&#x3e;, you need to pass a frame table with an args table.

For the preview warning, use &#x3c;code&#x3e;_warning&#x3c;/code&#x3e;.
