Keyboard
Simple library to listen for keystrokes from the keyboard
The code is inspired by termbox-go library.
Installation
Install and update this go package with go get -u github.com/eiannone/keyboard
Usage
Example of getting a single keystroke:
char, _, err := keyboard.GetSingleKey()
if (err != nil) {
panic(err)
}
fmt.Printf("You pressed: %q\r\n", char)Example of getting a series of keystrokes with a blocking GetKey() function:
package main
import (
"fmt"
"github.com/eiannone/keyboard"
)
func main() {
if err := keyboard.Open(); err != nil {
panic(err)
}
defer func() {
_ = keyboard.Close()
}()
fmt.Println("Press ESC to quit")
for {
char, key, err := keyboard.GetKey()
if err != nil {
panic(err)
}
fmt.Printf("You pressed: rune %q, key %X\r\n", char, key)
if key == keyboard.KeyEsc {
break
}
}
}Example of getting a series of keystrokes using a channel:
package main
import (
"fmt"
"github.com/eiannone/keyboard"
)
func main() {
keysEvents, err := keyboard.GetKeys(10)
if err != nil {
panic(err)
}
defer func() {
_ = keyboard.Close()
}()
fmt.Println("Press ESC to quit")
for {
event := <-keysEvents
if event.Err != nil {
panic(event.Err)
}
fmt.Printf("You pressed: rune %q, key %X\r\n", event.Rune, event.Key)
if event.Key == keyboard.KeyEsc {
break
}
}
}
