Template:Void/doc

This template does nothing visually. Technically, it throws away its parameters and outputs the null string.

Use cases
It is useful for programming advanced templates, and is often used within a template to the right of an equals sign. It may also be used in a template to disambiguate parsing of braces.

It can also be used to temporarily disable code, and unlike "commenting out" with, it nests. This means that  is valid, whereas   will produce.

It provides a particularly concise way of temporarily disabling templates, so the template name becomes the (ignored) first unnamed parameter. For example, suppose you have a page under construction for several days, and wish to remove that template between active editing sessions. Rather than delete the unused template, you can leave it in the wikisource and change from  to.

Another possible application would be to temporarily disable an infobox on an article page while a problem with the infobox template itself is resolved.

Furthermore, the template can be substituted:. This saves (and effectively purges) the page without saving a record in the page history, similar to a null edit, which is particularly useful for bots.
