Template:!/doc
 | This is a documentation subpage for Template:! It may contain usage information, categories and other content that is not part of the original template page. |
 | This template should have no transclusions, because it was replaced with a magic word. |
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 use syntax like {{Template:!}}, and do not supply a parameter, for example {{!|foo}}. In those cases, 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,
{{cquote|text=
{| class="wikitable"
|+ Caption text
|-
! Header text !! Header text
|-
| Example1 || Example2
|-
| Example3 || Example4
|}
}}
yields nonsense:
| “ |
{ |
” |
| — Example1 | ||
However escaping the bars with this magic word and similar templates gives:
{{cquote|text=
{{(!}}class{{=}}"wikitable"
{{!}}+ Caption text
{{!}}-
! Header text !! Header text
{{!}}-
{{!}} Example1 {{!!}} Example2
{{!}}-
{{!}} Example3 {{!!}} Example4
{{!)}}
}}
| “ |
|
” |
For how to include a table in a footnote, do:
Example 1{{refn|group=note|This is a note before}}
Example 2{{refn|group=note|1=<nowiki></nowiki>{{(!}}class{{=}}"wikitable"
{{!}}+Example table with two columns
!A column
!Another column
{{!}}-
{{!}} Some data
{{!}} Some more data
{{!)}}<nowiki></nowiki>}}
Example 3{{refn|group=note|This is a note after}}
==Notes==
{{Reflist|group=note}}
Be careful to follow this formatting, otherwise the table may gobble up the subsequent footnote. This can be unnoticeable if there is only one footnote, only causing an issue if a second footnote is added.
Example 1[note 1]
Example 2[note 2]
Example 3[note 3]
