{{lua|Module:String}}
This template is used to produce a simple loop. It is based on [[Module:String]], and there is no limit to the number of iterations it can perform.

== Usage ==

<pre>{{loop|times to repeat|string}}</pre>

If '''string''' contains an equals sign, you must put "|2=string" instead of "|string".

== Examples ==

{{markup|
<nowiki>{{loop|4|n}}</nowiki>|{{loop|4|n}}|
<nowiki>{{loop|25|test}}</nowiki>|{{loop|25|test}}|
<nowiki>{{#expr:2{{loop|50|*2}}}}</nowiki>|{{#expr:2{{loop|50|*2}}}}|
<nowiki>{{loop|3|{{CURRENTYEAR}}}}</nowiki>|{{loop|3|{{CURRENTYEAR}}}}}}<!-- Template:Mra -->

When the string being replicated includes "=", we have to precede the second parameter with "2=", or use {{tl|1==}}.
{{markup|
<nowiki>{{loop|9|2==}}</nowiki>|&#32;{{loop|9|2==}}|
<nowiki>{{loop|9|{{=}}}}</nowiki>|&#32;{{loop|9|{{=}}}}}}<!-- Template:Mra -->

Surrounding whitespace is always stripped; you must use {{ml|string|rep|section=#rep}} instead to preserve it.

{{markup|
<nowiki>{{#invoke:String|rep| hello |3}}</nowiki>|<span style{{=}}"white-space: pre">"{{#invoke:String|rep| hello |3}}"</span>|
<nowiki>{{loop|3| hello }}</nowiki>|"{{loop|3| hello }}"}}<!-- Template:Mra -->
