        # prints 1

Overview

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

Methods

pp_edistance

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
