This is an auxiliary template allowing to encode "<code>|</code>"
within template parameters. It is '''unnecessary''' to get a
"<code>|</code>" in these cases, better use "<code>&amp;#124;</code>"
for this purpose. However the "<code>|</code>" delimiter for a
Wiki table has to be escaped by a template if it's used
within a template, see also ].

Note that there's no such problem with "<code>!</code>" (exclamation mark), it
only affects "<code>|</code>" (vertical bar) in conjunction
with the ] mechanism within tables.

Magic word documentation[view] [edit] [history] [purge]
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
{{!)}}
}}


“
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 />{{(!}}class{{=}}"wikitable"
{{!+}} Example table with two columns
! A column
! Another column
{{!-}}
{{!}} Some data
{{!}} Some more data
{{!)}}<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.
