NAME

Text::Levenshtein - A port of the Perl 5 Text::Levenshtein

Build Status

SYNOPSIS

Find the Levenshtein edit distance.

This is a direct port of the Perl 5 version and should be close to 100% similar other then some Perl 6 idioms. The fastdistance routine was not ported since the logic was buggy and the code to fix it made it the same speed as the regular distance routine.

use Text::Levenshtein qw(distance);

print distance("foo","four");
# prints "2"

my @words=("four","foo","bar");
my @distances=distance("foo",@words);

print "@distances";
# prints "2 0 3"

DESCRIPTION

This module implements the Levenshtein edit distance. 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
