 | 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. |
Template:Tsh Lua error in package.lua at line 80: module 'Module:Transclusion_count/data/V' not found. This template does nothing visually. Technically, 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 -->.
It provides a particularly concise way of temporarily disabling templates, by prefixing them with ^|, 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 change that to {{In use}} during active editing sessions. Rather than delete the unused template, you can leave both templates in the wikisource and change from {{^|In use|...}}{{Under construction|...}} to {{In use|...}}{{^|Under construction|...}}.
Another possible application would be to temporarily disable an infobox on an article page while a problem with the infobox template itself is resolved.
Alternatives[edit source]
{{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.
