Str rightc/doc

Usage

{{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.

Easy to use and efficient string length comparison templates:

• {{str ≥ len}} – To check if a string is "longer or equally long" vs. "shorter" than a given length.
• {{str ≤ len}} – To check if a string is "shorter or equally long" vs. "longer" than a given length.
• {{str ≠ len}} – To check if a string is "not equal" vs. "equal" to a given length.
• {{str ≤ ≥ len}} – To check all three of "shorter", "equal" and "longer" at the same time.

Much less efficient string length template:

• {{str len}} – Takes a string as parameter and returns its length. Can count up to 500 in length.
