Template:Void

Template documentation[view] [edit] [history] [purge]

This template does nothing—more precisely, it throws away its parameters and outputs the null string.

It is useful for programming advanced templates, and is often is 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 {{void|foo {{void|bar}} baz}} is valid, whereas <!-- foo <!-- bar --> baz --> will produce baz -->.

Alternatives

{{Null}} redirects here. It's also possible to use {{ns:0}}, the empty/void/null string for the main namespace.

It can be used in place of <nowiki/> to break character sequence parsing, for example {{nowrap|{''a''}{{null}}}} to force the first closing brace to be treated as part of the template parameter instead of as the end of the template expression.
