print pp_edistance('Neil','Niel');
# prints 1
DESCRIPTION
Returns the true Damerau Levenshtein edit distance of strings with adjacent transpositions. Pure Perl implementation. Works correctly with utf8.
use Text::Levenshtein::Damerau::PP qw/pp_edistance/;
use utf8;
pp_edistance('XXXX','XXXX'),
# prints 1

pp_edistance
Arguments: source string and target string.
o OPTIONAL 3rd argument int (max distance; only return results with $int distance or less). 0 = unlimited. Default = 0.
Returns: int that represents the edit distance between the two argument. Stops calculations and returns -1 if max distance is set and reached.
Function to take the edit distance between a source and target string. Contains the actual algorithm implementation.
use Text::Levenshtein::Damerau::PP qw/pp_edistance/;
print pp_edistance('Neil','Niel');
