Tags : golang read-from-console has-prefix startswith to-lower-case

Just a code fragment below as supplement to tutorial on how to read until certain character to break loop. In this tutorial, the program will continue reading from the console(terminal) until a string that starts with bye.

Here you go :

 // run forever until user issue bye
 for {
 consoleReader := bufio.NewReader(os.Stdin)
 fmt.Print(">")

 input, _ := consoleReader.ReadString('\n')

 input = strings.ToLower(input)

 if strings.HasPrefix(input, "bye") {
 fmt.Println("Good bye!")
 os.Exit(0)
 }
 }
