<!-- PLEASE ADD CATEGORIES AND INTERWIKIS AT THE BOTTOM OF THIS PAGE -->

=== Usage ===
{{Tlx|Chop head and tail|<string>|<number>}}

This template removes <number> characters from the start and end of <string>.

: {{Tlx|Chop head and tail|12345654321|3}} gives {{Chop head and tail|12345654321|3}}.


==== Unlinking ====
This template can be used to "unlink" a linked parameter.

: {{Tlx|Chop head and tail|<nowiki>[[Einstein]]</nowiki>|2}} results in {{Chop head and tail|[[Einstein]]}}.

Because the default value of <number> is 2, this can be shortened to <code>{{Tlx|Chop head and tail|<nowiki>[[Einstein]]</nowiki>}}</code>.


=== Limitations ===
* Expensive.
* When used on strings with characters that carry a meaning in wiki-layout, this template will interpret the character as a layout instruction ([[bugzilla:12974]]). For example, {{Tlx|Chop head and tail|<nowiki>[[123;456]]</nowiki>}} renders as<br />{{Chop head and tail|[[123;456]]}}
* Supports the character set as defined by {{tl|Str index/getchar}}, so that e.g. {{Tlx|Chop head and tail|<nowiki>[[Nürnberg]]</nowiki>}} renders correctly as {{Chop head and tail|[[Nürnberg]]|nocategory=true}}. However, not all characters are in this set.
