Magic word documentation[view] [edit] [history] [purge]

The magic word {{!}} is used to escape a vertical bar character "|" in wikitext markup, causing the parser to temporarily not interpret it as a special character.

This used to be a template, but for speed reasons, the MediaWiki parser was changed in July 2014 to instantly interpret {{!}} as "|" and ignore this template, making {{!}} a magic word. You can continue to use the code in exactly the same way as before.

Do not transclude the template, instead of using the magic word, by using template-specific syntax like {{Template:!}}, or by supplying a parameter, for example {{!|foo}}. The template transcludes as an error message: Error: The retired template {{!}} has been transcluded; see mw:Help:Magic words#Other for details. To fix this, use only the code {{!}} to generate the | character.

Usage

The code {{!}} is used to escape the vertical bar character, |, so that it is interpreted later than it would be otherwise. This is mostly useful when trying to include a table in a template. For example,

{{rquote|none|text=
{| class="wikitable"
|+ Caption text
|-
! Header text !! Header text
|-
| Example || Example
|-
| Example || Example
|}
}}

yields nonsense:

However escaping the bars with this magic word and similar templates gives:

{{rquote|none|<nowiki>
</nowiki>{{(!}} class{{=}}"wikitable"
{{!}}+ Caption text
{{!}}-
! Header text !! Header text
{{!}}-
{{!}} Example {{!!}} Example
{{!}}-
{{!}} Example {{!!}} Example
{{!}}}
}}
