New page {{Documentation subpage}} {{transclusionless|should=yes|reason=it was replaced with a [[Help:Magic words|magic word]]}} The magic word <code><nowiki>{{!}}</nowiki></code> is used to escape a [[vertical bar]] character "|" in [[wp:wikitext|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 <code><nowiki>{{!}}</nowiki></code> as "|" and ignore this template, making <code><nowiki>{{!}}</nowiki></code> a [[mw:Help:Magic words|magic word]]. You can continue to use the code in exactly the same way as before. Do not use syntax like <code><nowiki>{{Template:!}}</nowiki></code>, and do not supply a parameter, for example <code><nowiki>{{!|foo}}</nowiki></code>. In those cases, the template transcludes as an error message: {{error|Error: The retired template {{tn|!}} has been transcluded; see [[mw:Help:Magic words#Other]] for details. To fix this, use only the code {{Magic word|!}} to generate the | character.}} == Usage == The code <code><nowiki>{{!}}</nowiki></code> is used to [[Escape_character|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, <syntaxhighlight lang="wikitext"> {{cquote|text= This is text before {| class="wikitable" |+ Caption text |- ! Header text !! Header text |- | Example 1 || Example 2 |- | Example 3 || Example 4 |} This is text after }} </syntaxhighlight> yields nonsense: {{cquote|text=<nowiki /> This is text before {| class="wikitable" |+ Caption text |- ! Header text !! Header text |- | Example 1 || Example 2 |- | Example 3 || Example 4 |} This is text after }} However escaping the bars with this magic word and similar templates gives: <syntaxhighlight lang="wikitext"> {{cquote|text= This is text before {{(!}} class{{=}}"wikitable" {{!+}} Caption text {{!-}} ! Header text !! Header text {{!-}} {{!}} Example 1 {{!!}} Example 2 {{!-}} {{!}} Example 3 {{!!}} Example 4 {{!)}} This is text after }} </syntaxhighlight> {{cquote|text=<nowiki /> This is text before {{{!}} class{{=}}"wikitable" {{!+}} Caption text {{!-}} ! Header text !! Header text {{!-}} {{!}} Example 1 {{!!}} Example 2 {{!-}} {{!}} Example 3 {{!!}} Example 4 {{!)}} This is text after }} For how to include a table in a footnote, do: <syntaxhighlight lang="wikitext"> Example 1{{refn|group=note|This is a note before}} Example 2{{refn|group=note|1=<nowiki />This is text before {{(!}} class{{=}}"wikitable" {{!+}} Caption text {{!-}} ! Header text !! Header text {{!-}} {{!}} Example 1 {{!!}} Example 2 {{!-}} {{!}} Example 3 {{!!}} Example 4 {{!)}} This is text after <nowiki />}} Example 3{{refn|group=note|This is a note after}} ==Notes== {{Reflist|group=note}} </syntaxhighlight> Be careful to follow this formatting, [[Special:Diff/1078738513|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{{refn|group=note|This is a note before}} Example 2{{refn|group=note|1=<nowiki />This is text before {{(!}} class{{=}}"wikitable" {{!+}} Caption text {{!-}} ! Header text !!
