How to Implement Language Detection in Go

Go does not have a built-in language detection feature; you must use a third-party library like github.com/cloudfoundry-incubator/go-langdetect or github.com/abadojack/whatlanggo to identify the language of a text string. Install the library and pass your text to its detection function to receive the identified language code.

package main

import (
	"fmt"
	"github.com/abadojack/whatlanggo"
)

func main() {
	text := "Hello world"
	lang := whatlanggo.Detect(text)
	fmt.Println(lang.Code) // Output: en
}

Language detection is the process of figuring out what human language a piece of text is written in. Since Go doesn't include this tool by default, you need to add a small helper library to your project to do the work for you. Think of it like adding a translator to your team who can instantly recognize the language of any document you hand them.
