Editing Help/Templates (section)

==== Template-generated brackets ==== <!--T:351-->
</translate>
<translate><!--T:352--> An alternate technique for passing arguments with unmatched brackets is to wrap them in another template.</translate>
<translate><!--T:407--> In that situation, (which exists with <tvar name=1></tvar> and <tvar name=2>)</tvar> on this wiki), the unmatched brackets will be rendered literally, and not decoded as another template call.</translate>
<translate><!--T:353--> For example:</translate>
<syntaxhighlight lang="wikitext">
t1demo}}
</syntaxhighlight>
<translate><!--T:354--> results in:</translate>
t1demo}}

<translate><!--T:355--> When [[<tvar name=1>Special:MyLanguage/Help:Substitution</tvar>|substituting]] a template, template inclusions are parsed once when the subst happens (with the same caveats explained above) and then a second time when rendering the resulting wikitext.</translate>
<translate><!--T:356--> For example:</translate> 
<syntaxhighlight lang="wikitext">
t1demo|foo}}
</syntaxhighlight>
<translate><!--T:357--> will expand on save to:</translate>
<syntaxhighlight lang="wikitext">

</syntaxhighlight>
<translate><!--T:358--> which will then render as:</translate>

 

<translate><!--T:359--> If the wikitext generated via the first subst itself includes "subst:" syntax it will not be processed on the same save, but may be on the next save.</translate>
<translate><!--T:360--> This technique may be used to implement [[<tvar name=1>Special:MyLanguage/Manual:Recursive conversion of wikitext</tvar>|recursive substitutions]] that take multiple saves to evaluate.</translate>
