How can I get keyboard input data in Go?

I want to be able to tell if a user presses things like <kbd>Ctrl</kbd>+[something] or <kbd>Esc</kbd> on their keyboard in Go. The program runs in a Linux environment inside a terminal.

1. If you just want to simply read the string or bytes, you can do this

in := bufio.NewScanner(os.Stdin)
data := in.Bytes()

2. If you want to capture the system semaphore, you can get it by registering the semaphore monitor

signal.Notify(os.Interrupt, os.Kill) // os.Interrupt=0x2 os.Kill=0x9

3. Get ASCII code from a key press(cross-platform) (use github.com/nsf/termbox-go)

import (
	"fmt"
	term "github.com/nsf/termbox-go"
)

func main() {
	err := term.Init()
	if err != nil {
		panic(err)
	}
	defer term.Close()

	for {
		switch ev := term.PollEvent(); ev.Type {
		case term.EventKey:
			switch ev.Key {
			case term.KeyEsc:
				term.Sync()
				fmt.Println("ESC pressed")
			case term.KeyF1:
				term.Sync()
				fmt.Println("F1 pressed")
			case term.KeyInsert:
				term.Sync()
				fmt.Println("Insert pressed")
			case term.KeyDelete:
				term.Sync()
				fmt.Println("Delete pressed")
			case term.KeyHome:
				term.Sync()
				fmt.Println("Home pressed")
			case term.KeyEnd:
				term.Sync()
				fmt.Println("End pressed")
			case term.KeyPgup:
				term.Sync()
			case term.KeyArrowRight:
				term.Sync()
				fmt.Println("Arrow Right pressed")
			case term.KeySpace:
				term.Sync()
				fmt.Println("Space pressed")
			case term.KeyBackspace:
				term.Sync()
				fmt.Println("Backspace pressed")
			case term.KeyEnter:
				term.Sync()
				fmt.Println("Enter pressed")
			case term.KeyTab:
				term.Sync()
				fmt.Println("Tab pressed")

			default:
				term.Sync()
				fmt.Println("ASCII : ", ev.Ch)

			}
		case term.EventError:
			panic(ev.Err)
		}
	}
}

4. Read single characters

consoleReader := bufio.NewReaderSize(os.Stdin, 1)
input, _ := consoleReader.ReadByte()
ascii := input

// ESC = 27 and Ctrl-C = 3
if ascii == 27 || ascii == 3 {
	fmt.Println("Exiting...")
	os.Exit(0)
}

fmt.Println("ASCII : ", ascii)
