This is a minimal working example for those running a UNIX system:
package main
import (
"fmt"
"os"
"os/exec"
)
func main() {
// disable input buffering
exec.Command("stty", "-F", "/dev/tty", "cbreak", "min", "1").Run()
// do not display entered characters on the screen
exec.Command("stty", "-F", "/dev/tty", "-echo").Run()
var b []byte = make([]byte, 1)
for {
os.Stdin.Read(b)
fmt.Println("I got the byte", b, "("+string(b)+")")
}
}
