Golang : Translate language with language package example

Just a simple example on how to use the language package to do language translation. Not a google translate type of translation engine.... still need to provide exact match for each translation to work.

Putting this here for my own future reference.

Here you go!

 package main

 import (
  //"fmt" -- replace with message package in this example

  "golang.org/x/text/language"
  "golang.org/x/text/language/display"
  "golang.org/x/text/message"
 )

 func main() {

  // define a direct translation from English to Dutch
  message.SetString(language.Dutch, "In %v people speak %v.", "In %v spreekt men %v.")

  fr := language.French
  region, _ := fr.Region()
  for _, tag := range []string{"en", "nl"} {
 p := message.NewPrinter(language.Make(tag))

 p.Printf("In %v people speak %v.", display.Region(region), display.Language(fr))
 p.Println()
  }

  // define a direct translation from English to Chinese
  message.SetString(language.Chinese, "In %v people speak %v.", "在%v说%v.") // * Must match for translation to work

  zh := language.Chinese
  region, _ = zh.Region()
  for _, tag := range []string{"en", "zh"} {
 p := message.NewPrinter(language.Make(tag))

 p.Printf("In %v people speak %v.", display.Region(region), display.Language(zh)) // * Must match for translation to work
 p.Println()
  }

  // define a direct translation from English to Malay
  message.SetString(language.Malay, "In %v people speak %v.", "Orang %v berbahasa %v.")

  msmy := language.Malay
  region, _ = msmy.Region()
  for _, tag := range []string{"en", "ms"} {
 p := message.NewPrinter(language.Make(tag))

 p.Printf("In %v people speak %v.", display.Region(region), display.Language(msmy))
 p.Println()
  }
 }

Output:

In France people speak French.

In Frankrijk spreekt men Frans.

In China people speak Chinese.

在中国说中文.

In Malaysia people speak Malay.

Orang Malaysia berbahasa Melayu.
