Go bindings for the snowball libstemmer library including porter 2

Go (golang) bindings for libstemmer

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

Requirements

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.

Installation

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

Usage

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()

Testing

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!
