一般获取命令行按键是阻塞工的,之前使用github.com/eiannone/keyboard库,远程获取键盘没问题,但本地居然不行。
package main
import (
"fmt"
"os"
"time"
"os/exec"
)
func main() {
ch := make(chan string)
go func(ch chan string) {
// 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)
ch <- string(b)
}
}(ch)
for {
select {
case stdin, _ := <-ch:
fmt.Println("Keys pressed:", stdin)
default:
fmt.Println("Working..")
}
time.Sleep(time.Millisecond * 100)
}
}
