{{Str rightc|<string>|<count>}}{{Str rightc|<string>|<count>|<result if empty>}}
Gives a substring of length <count> of characters from the right-side end of the string. If the parameter 1 <string> is empty, then immediately returns with parameter 3 (or nothing), and skips all the complex processing usually needed to extract a substring.
If <count> is invalid, empty or undefined, this template goes berserk, so don't do that.
Limitations
- Up to 100 chararacters in the input string. If possible, first check length of input string using {{Str len}}. Using strings longer than 100 characters may result in the error "max index is 100 for str_sub".
- Limited set of characters.
- Expensive (if used too many times per page, generates "Wikimedia Foundation Server Error").
- Returning parameter 3, when parameter 1 is empty, was added 8 May 2010.
Examples
- {{Str rightc| lorem ipsum dolor sit amet | 10 }} → r sit amet
- {{Str rightc| lorem ipsum dolor sit amet | 1 }} → t
- {{Str rightc| lorem ipsum dolor sit amet | 0 }} →
- {{Str rightc| | 1 | empty }} → empty
- {{Str rightc |123456789.123456789.123456789.123456789.123456789.123456789.123456789.123456789.123456789.123456789.1 | 99}} → 3456789.123456789.123456789.123456789.123456789.123456789.123456789.123456789.123456789.123456789.max index is 100 for str sub long
