Template:Void
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. Unlike "commenting out" using HTML <!-- -->
, 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 the template name with ^|
, making the template name become 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 wikitext 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.
A deeper no-op is {subst:void|foobar}
or {subst:^|foobar}
. It disappears completely upon saving.
Alternatives
{Null}
also redirects here. It is 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.
