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!
