Template: Void/doc
| 40px | This is a documentation subpage for Template:Void. It contains usage information, categories and other content that is not part of the original template page. |
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 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.
