Text::LevenshteinXS(3) An XS implementation of the Levenshtein edit distance

SYNOPSIS


use Text::LevenshteinXS qw(distance);
print distance("foo","four");
# prints "2"
print distance("foo","bar");
# prints "3"

DESCRIPTION

This module implements the Levenshtein edit distance in a XS way.

The Levenshtein edit distance is a measure of the degree of proximity between two strings. This distance is the number of substitutions, deletions or insertions (``edits'') needed to transform one string into the other one (and vice versa). When two strings have distance 0, they are the same. A good point to start is: <http://www.merriampark.com/ld.htm>
