terminal

A custom terminal witch can use up/down press to call history command, and tab to call syscall command.

use

getch

ch, paste := getch()  //ch is the keyboard value you've press，paste is the value if you use command+v

if you'll create a terminal, you can do like so:

	systemCmdList := []string{"hosts", "services", "connect", "connects", "relase", "log", "start", "stop", "restart", "delete", "exit"}
	term := NewTerminal("> ")
	term.SetSystemCommand(systemCmdList)
	for {
		fmt.Printf("> ")
		cmd := term.GetCommand()
		fmt.Println()
		//fmt.Println("\ncmd = ", cmd, "  len = ", len(cmd))
		if cmd == "exit" {
			break
		}
	}

the system command list will used when you press tab keyboard. if you use func GetCommand,you can call history command by ⬆️ and ⬇️. if terminal request user to input username then you can call term.GetUser(), if so, it will not record to history list, at the same time, if get password you can call term.GetPassword(), it will echo '*' when you input password.
