Text::Levenshtein::Damerau::PP - Pure Perl Damerau Levenshtein edit distance.
use Text::Levenshtein::Damerau::PP qw/pp_edistance/; print pp_edistance('Neil','Niel'); # prints 1
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('ⓕⓞⓤⓡ','ⓕⓤⓞⓡ'), # prints 1
Arguments: source string and target string.
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'); # prints 1 print pp_edistance('Neil','Nielx',1); # prints -1
