如何在CLI应用程序（golang）中执行自动完成命令？

I want to do autocomplete my commands when press "TAB" key "\t" and execute command when press "ENTER" key "? ". This code for example:

package main
import (
    "bufio"
    "fmt"
)
func main() {
    reader := bufio.NewReader(os.Stdin)
    command, err := reader.ReadString('
')
    if err != nil {
         fmt.Printf("%s
", err)
    } else {
        fmt.Printf("%s
", command)
    }
}

If you want bash-like functionality, then it's a lot more complicated than just using a bufio reader.
