<!-- Categories and interwikis go at the bottom of this page. -->

== Usage ==
{{tlx|Trim leading | &lt;input&gt;&nbsp;| &lt;prefix&gt;&nbsp;}}

Trims up to six instances of &lt;prefix&gt; (such as: 0 or "anti-") from the beginning of &lt;input&gt;. &lt;Prefix&gt; is set to "0" by default (for removing leading zeroes from numbers). Template will not properly work beyond the first whitespace in the input.

=== Limitations === 
* Up to 100 chararacters in the input string. If possible, first check length of input string using {{Tl|Str len|<string>}}. Using strings longer than 100 characters may result in the error '''''"<span style="color:#CC1100">max index is 100 for str_sub</span>"'''''.
* Limited set of characters.
* Snags on whitespace.
* Expensive.
