More than 3 years have passed since last update.

中身補足

termbox-goというライブラリを利用してGUI風CUIを実現しています。

こんな感じでキーイベント拾えます。

for {
    switch ev := termbox.PollEvent(); ev.Type {
    case termbox.EventKey:
        switch ev.Key {
        case termbox.KeyEsc:
            //Escキー押した時の処理
        case termbox.KeyArrowUp:
            //上キー押した時の処理
        case termbox.KeyArrowDown:
            //下キー押した時の処理
        default:
        }
    default:
    }
}

こんな感じで任意の座標に文字を配置できます。

termbox.SetCell(x, y,str, FontColor, BackgroundColor)

なんだかRogueクローンが作りたくなるライブラリですね。

Go言語は並列処理がとても簡単に書けるので、この手のちょっとしたアクション要素のあるコマンドが実装しやすいです。
