This simple library provides Go (golang) bindings for the snowball libstemmer library including the popular porter and porter2 algorithms.

You'll need the development package of libstemmer, usually this is simply a matter of:

sudo apt-get install libstemmer-dev

... or you might need to install it from source.

First, ensure you have your GOPATH env variable set to the root of your Go project:

export GOPATH=`pwd`
export PATH=$PATH:$GOPATH/bin

Then this cute statement should do the trick:

go get github.com/rjohnsondev/golibstemmer

Basic usage:

package main

import "github.com/rjohnsondev/golibstemmer"
import "fmt"
import "os"

func main() {
    s, err := stemmer.NewStemmer("english")
    defer s.Close()
    if err != nil {
        fmt.Println("Error creating stemmer: "+err.Error())
        os.Exit(1)
    }
    word := s.StemWord("happy")
    fmt.Println(word)
}

To get a list of supported stemming algorithms:

list := stemmer.GetSupportedLanguages()

You can execute the basic included tests with:

go test

If you have issues, double check you've installed the libstemmer development library.

If you still have issues, let me know!
