Template:Chop head and tail/doc

Usage

{{Chop head and tail|<string>|<number>}}

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

{{Chop head and tail|12345654321|3}} gives Template:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ len.

Unlinking

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

{{Chop head and tail|[[Einstein]]|2}} results in Template:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ len.

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

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, {{Chop head and tail|[[123;456]]}} renders as
  Template:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ len
• Supports the character set as defined by {{Str index/getchar}}, so that e.g. {{Chop head and tail|[[Nürnberg]]}} renders correctly as Template:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ lenTemplate:Str ≥ len. However, not all characters are in this set.
