1．はじめに
どうも、趣味でデータ分析している猫背なエンジニアです。
今回はクソアプリ企画に参加していこうと思います。
警告
これはクソアプリです。
実際の情報とは乖離します。ご注意ください。
2．「MS-DOS風」フライト情報CLIアプリ
■ 概要
みなさまは、よく飛行機に乗りますか？私はもちろん乗りません。ですが、たまにフライト情報を見たい時があります。そんなときに気軽に情報を取得できるものがあれば最高ですよね。しかもローカルで動くフライト情報表示アプリ。
■ 機能設計
機能としては以下のようになっています。
〇 それっぽいスケジュール
〇 ANSIカラーで無理やりDOS感を演出
〇 ENTERでリロードすると状況が変わる
〇 たまに勝手に遅延・欠航する
〇 うるさい広告バナー付き
〇 何もしてないのにビープ音が鳴る
■ 動作イメージ
MS-DOS Flight Info v0.13 (Crappy Edition)

■ フライト情報の生成
特殊なライブラリは一つも使っていません。
航空会社コード / 発着地 / 出発予定時刻 / ステータス（On Time / Delayed / Cancelled など） / ゲート番号は気合で生成しています。
最近のPCは素晴らしいですね。
■ 重要イベントでビープ音
遅延・欠航が発生すると…… ﾋﾟｯと音が鳴る設計にしています。
これで急いでいるときに何かあっても安心ですね。
■ 検索・詳細表示も一応ある
検索機能も搭載しており、自分が搭乗する便が通常通り動いているかも確認できますね。
S で検索（便名 / 出発地 / 到着地）
V JC012 で詳細表示

3. おわりに
今回は前回のコウメ.pyに引き続き、実用性はない満足度は高いアプリを作りました。
今後はここから得た技術要素をもとに何か得られたらええなと思います（笑）
