Installation

You can install the packages by using an appropriate variant of goinstall github.com/cskau/gofnv/fnv1a64. If you do this, the import statement in your go programs will be something like import github.com/cskau/gofnv/fnv1a64.

Example usage

package main

import (
    "io"
    "fmt"
    "github.com/cskau/gofnv/fnv1a64"
)

func main() {
    str := "Fowler-Noll-Vo"
    hasher := fnv1a64.New()
    io.WriteString(hasher, str)
    hash := hasher.Sum64()
    fmt.Printf( "fnv1a64(\"%s\") = 0x%x\n", str, hash )
}

To run the application, put the code in a file called hello-fnv.go and run:

8g hello-fnv.go && 8l -o hello-fnv hello-fnv.8 && ./hello-fnv
