Cách sử dụng { { Chop head and tail | <string>| <number>} }
This template removes <number> characters from the start and end of <string>.
{ { Chop head and tail | 12345654321| 3} }
Unlinking This template can be used to "unlink" a linked parameter.
{ { Chop head and tail | [[Einstein]]| 2} } Because the default value of <number> is 2, this can be shortened to { { Chop head and tail | [[Einstein]]} }
Giới hạn 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]]} } Supports the character set as defined by { { Str index/getchar } } , so that e.g. { { Chop head and tail | [[Nürnberg]]} }
