Leven - Fast implementation of Levenstein distance written in Go

This implementation have equal or fastest implementation when using:

• Prefixed words
• Postfixed words
• Fullscan

Installation

go get github.com/m1ome/leven

Usage

package main

import (
    "fmt"
    "github.com/m1ome/leven"
)

func main() {
    s1 := "kitten"
    s2 := "sitten"
    fmt.Printf("The distance between %v and %v is %v\n", s1, s2, leven.Distance(s1, s2))
    // The distance between kitten and sitten is 1
}
