Keyboard event on console in Golang
问题
我现在正在使用Golang创建基于CUI的扫雷游戏。
我想处理键盘事件来操作游戏。
你有什么办法可以实现这个吗？

每个操作系统处理键盘按键的方式略有不同。你可以编写一个库，将它们抽象成一个通用的接口，或者更好的是使用别人已经编写好的库。
如评论中所提到的，termbox-go 是一个不错的选择。它很稳定并且被广泛采用。
另一个不错的选择是 eiannone/keyboard，它更小巧，正在积极开发，并受到 termbox-go 的启发。
针对你的特定用例，你可能需要一个监听键盘事件的 Go 协程和一个处理这些事件的通道。以下是使用他们文档中的键盘库的示例代码：
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
}
}
}

Each operating system has a slightly different way of handling keyboard presses. You could write a library that abstracts these into a common interface, or better, use one that someone else already wrote.
As mentioned in the comments, termbox-go is a good option. It's stable and has broad adoption.
Another good option is eiannone/keyboard which is much smaller, actively developed and inspired by termbox-go.
For your specific use case you'll likely want to have a go routine that's listening to keyboard events and a channel that handles them. Here's the example using the keyboard library from their documentation.
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
}
}
}
