Editing Help/Templates (section)

=== Using pipes in parameter values === <!--T:361-->
</translate>
<translate><!--T:362--> A parameter value cannot contain a pipe character (<tvar name=1>|</tvar>), because it would be interpreted as the end of that parameter and the start of the next parameter.</translate>
<translate><!--T:363--> This can be worked around by using the  <tvar name=2><code><nowiki></nowiki></code></tvar>, or the HTML entity <tvar name=3>&amp;124;</tvar>.</translate>
<translate><!--T:364--> The two methods of doing this have slightly different behavior, which can be relevant in some corner cases like when a template is producing [[<tvar name=1>Special:MyLanguage/Help:Tables</tvar>|wikitable]] syntax.</translate>

<translate><!--T:365--> Example:</translate>
<code><nowiki></nowiki></code>
<translate><!--T:366--> produces:</translate>
 

<translate><!--T:367--> The "<tvar name=1>def</tvar>" doesn't display because it is treated as part of another unnamed parameter, which the template does not use.</translate>

<code><nowiki>def}}</nowiki></code>
<translate><!--T:368--> produces:</translate>
def}} 

<translate><!--T:369--> The "<tvar name=1>def</tvar>" displays properly.</translate>

<code><nowiki></nowiki></code>
<translate><!--T:370--> produces:</translate>
 

<translate>
<!--T:371-->
The "<tvar name=1>def</tvar>" displays properly again.
