Levenshtein distance between two strings in julia

This module provides a simple, but generic implementation of the Levenshtein distance function.

julia> Pkg.add("Levenshtein")

Standard Levenshtein distance

julia> levenshtein("polynomial", "exponential")
6

Levenshtein distance with custom insertion, deletion, substitution costs

julia> ins, del, sub = 3, 2, 1
(3,2,1)

julia> levenshtein("polynomial", "exponential", ins, del, sub)
8
