== Usage ==

This is the {{t<noinclude>n</noinclude><includeonly>l</includeonly>|!}} meta-template. Its use is analogous to an {{wp|escape_character}}.

This is an auxiliary template allowing the encoding of "<code>|</code>" within template parameters, because the pipe character is normally interpreted as a separator. This template is necessary if the character is used in wiki table syntax, or if the parameter is automatically wikilinked and you wish to use a pipe to specify different link text from the target page name. In other cases it is better to use "<code>&#124;</code>".

This template cannot be used for putting the character as text in a wiki table; in that case, again, "<code>&#124;</code>" can be used.

Note that no special template is needed for "<code>!</code>" (exclamation mark).

This is a [[WP:high-risk template|high-risk template]], and it usually cannot be [[Wikipedia:wikipedia:Substitution|substituted]] (see conditions for substring on [[#Substitution|the section below]]).

=== Substitution ===
It is possible to {{wp|Wikipedia:Substitution|substitute}} <nowiki>{{!}}</nowiki> only if an unescaped "'''<code>|</code>'''" works as expected, i.e. after substituting the template containing <nowiki>{{!}}</nowiki>, or after eliminating an
[[mw:Help:Extension:ParserFunctions#.23if|#if]] containing <nowiki>{{!}}</nowiki>.

=== A simple example ===

The following template code for {{tl|Quotation}} using an ordinary pipe character,
* <code><nowiki>{{Quotation|It is not possible to use an ordinary pipe character | in template parameters, as it will be interpreted as a separator.|[[Help:Template#Usage hints and workarounds]]}}</nowiki></code>

produces:
{{Quotation|It is not possible to use an ordinary pipe character | in template parameters, as it will be interpreted as a separator.|[[Help:Template#Usage hints and workarounds]]}}

whereas this code using the <nowiki>{{!}}</nowiki> meta-template,
* <code><nowiki>{{Quotation|It is not possible to use an ordinary pipe character {{!}} in template parameters, as it will be interpreted as a separator.|[[Help:Template#Usage hints and workarounds]]}}</nowiki></code>

produces:
{{Quotation|It is not possible to use an ordinary pipe character {{!}} in template parameters, as it will be interpreted as a separator.|[[Help:Template#Usage hints and workarounds]]}}
