Prelude.substr(3kaya)
NAME
Prelude::substr - Return a substring.
SYNOPSIS
String substr( String x, Int i, Int len )
ARGUMENTS
x The original string
i The starting index
len The substring length
DESCRIPTION
Starting at character i , return the len characters long substring.
Throws an Exception if len is negative, or if i is out-of-bounds. In
Kaya 0.2.4 and earlier, an Exception was also thrown if len was zero.
The empty string is now returned in this case.
- If the starting index is negative, then it will be counted in characters from the end of the string.
- x = "abcdef";
s = substr(x,0,2); // "ab"
s = substr(x,4,1); // "e"
s = substr(x,3,10); // "def" ( len
truncated)
s = substr(x,-4,2); // "cd"
