{{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 45654.
This template can be used to "unlink" a linked parameter.
{{Chop head and tail|[[Einstein]]|2}} results in Einstein.
Because the default value of <number> is 2, this can be shortened to {{Chop head and tail|[[Einstein]]}}
- 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
123;456
- Supports the character set as defined by {{Str index/getchar}}, so that e.g.
{{Chop head and tail|[[Nürnberg]]}} renders correctly as Nürnberg. However, not all characters are in this set.
