Modul:If preview/doc forrásának megtekintése

{{lua|Modul:If preview/configuration}}
{{uses TemplateStyles|Modul:If preview/styles.css}}

This module implements {{Tl|If preview}} and {{Tl|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 <code>main()</code>, you need to pass a frame table with an args table.

For the preview warning, use <code>_warning()</code>.
