NAME

       Text::Levenshtein::Damerau::PP - Pure Perl Damerau Levenshtein edit distance.

SYNOPSIS

               use Text::Levenshtein::Damerau::PP qw/pp_edistance/;

               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

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
