SYNOPSIS

10               use Text::Levenshtein::Damerau::PP qw/pp_edistance/;
11
12               print pp_edistance('Neil','Niel');
13               # prints 1

20               use Text::Levenshtein::Damerau::PP qw/pp_edistance/;
21               use utf8;

METHODS

27   pp_edistance
28       Arguments: source string and target string.
29
30       ·   OPTIONAL 3rd argument int (max distance; only return results with
31           $int distance or less). 0 = unlimited. Default = 0.
32
33       Returns: int that represents the edit distance between the two
34       argument. Stops calculations and returns -1 if max distance is set and
35       reached.
36
37       Function to take the edit distance between a source and target string.
38       Contains the actual algorithm implementation.
