Initializing the Translator

package main

import (
	"fmt"
	"log"
	"github.com/gouef/translator"
)

func main() {
	translator.Init()

	// Load YAML translations
	yamlTranslator, err := translator.NewYaml("locales")
	if err != nil {
		log.Fatal(err)
	}
	translator.Register(yamlTranslator)

	// Set active language
	err = translator.SetLanguage("cs_CZ")
	if err != nil {
		log.Fatal(err)
	}

	// Translate a key
	fmt.Println(translator.Translate("hello"))
}

Using PO Translations

package main

import (
	"fmt"
	"log"
	"github.com/gouef/translator"
)

func main() {
	translator.Init()

	poTranslator, err := translator.NewPO("locales")
	if err != nil {
		log.Fatal(err)
	}
	translator.Register(poTranslator)

	err = translator.SetLanguage("cs_CZ")
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(translator.Translate("errors.hello"))
}
