language detection

This is a go wrapper around langid.c. The repo include all the necessary c code and the default trained model to be able to use as is.

Installation

Depends on protobuf-c library, in ubuntu this can be installed using

sudo apt-get install libprotobuf-c-dev

Install the go library

go get github.com/cliqz-oss/langid_go

Usage

package main

import (
	"fmt"
	"github.com/cliqz-oss/langid_go"
)

func main() {
	li := langid_go.NewIdfr()
    
    // de-allocates the language model from memory.
	defer li.Destroy()
    
	fmt.Println(li.DetectLanguage("hello world"))
}

Updating foreign code and models.

All C files except langid_go.{c,h} are copied from langid.c repo, including model.c which contains a generated model. To update these files remove them

from repo, and pass LDFLAG: -lliblangid to cgo (here: https://github.com/cliqz-oss/langid_go/blob/master/langid_go.go#L3 )

Bugs and todos

  1. Loading your own model is not supported.
  2. No interface to get the probability values out.
