[ryosan-470]

表題通り。もう流石にCoffeescriptなんか書きたくないし時代は変わったw

Golangで書き直してやりたい。

正規表現でユーザー入力を解析して特定のときに特定のことをするみたいなハンドラーをどう書くのか謎い

雰囲気的には構造体を用意してパターンマッチかな?

type Command struct {
    pattern string
    handler func()
}

var commands []Command

commands.append(&Command{"^ping", pingHandler})
...

for _, c := range commands {
    if regexp.MatchString(c.pattern, input) {
        c.handler()
    }
}

こんな感じ。色々とできるのか不安だけど、そこら辺は調べるしか無い

正規表現じゃなくてコマンド式にすると、扱いやすそうに思える

ctftimesの奴、coffeescript見ながら取得するだけの奴作ってみたけど、replace-goに置く感じでも大丈夫？
