;; 第1回 Scheme コードバトン (CL fork) | |
;; | |
;; ■ これは何か? | |
;; 「Scheme のコードをバトンのように回していき面白い物ができあがるのを楽しむ遊びです。」のCL版です。 | |
;; 次回 Shibuya.lisp で成果を発表します。 | |
;; Scheme 初心者のコードを書くきっかけに、中級者には他人のコードを読む機会になればと思います。 | |
;; | |
;; ■ 2 つのルール | |
;; | |
;; (1)自分がこれだと思える変更をコードに加えて2日以内に次の人にまわしてください。 | |
;; 「人に優しい」変更なら何でも良い。1文字の変更でも可。 | |
;; 「人に優しい」とは例えば、次の人が読みやすいコードを書くなど。 | |
;; コードを削るのもあり。 | |
;; | |
;; (2)次の人にまわしコードが変更されるのを"見守る"。 | |
;; この説明書きを含めてバトンが伝わった事を必ず確認してください。 | |
;; 止まっていたら助けてあげてください。 | |
;; | |
;; ■ バトンの回し方 | |
;; | |
;; (1) 回ってきたバトンは http://gist.github.com/xxxx という URL のはずです。 | |
;; (2) fork をクリックしてください(アカウントを持っていない人はこのとき作成します) | |
;; (3) edit で変更したファイルを貼り付けます。 | |
;; (4) 自分が fork した新しい URL を回してください | |
;; | |
;; | |
;; ■ 良くある質問 | |
;; | |
;; (a) 初心者です。参加したいけどちょっと不安です。 | |
;; higepon がフォローしますので大丈夫です。分からない事があれば遠慮無く聞いてください。 | |
;; | |
;; (b) 次にまわす人がいません | |
;; higepon に知らせてください。twitter, 日記のコメントなどで。 | |
;; | |
;; (c) 次の人がコードを止めてしまいました | |
;; 残念ですが別の人にバトンを渡してください。 | |
;; | |
;; (d) Mosh で動かないとダメですか? | |
;; いいえ。Scheme なら何でも良いです。Gauche, Ypsilon 用に書き換えるのも面白いですね。 | |
;; そのときは起動方法の説明も変えてください。 | |
;; | |
;; ■ バトンの行方を記録 | |
;; 名前(URL):一言 | |
;; 1. higepon (http://d.hatena.ne.jp/higepon/): 最初はコマンドライン英単語暗記ツールでした。これが何に化けるのか楽しみ。全く別物になるかな? | |
;; 2. g000001 (http://cadr.g.hatena.ne.jp/g000001/): CLに翻訳してみましたが、higeponさんのコードとは考え方が結構違うものになってしまいました! | |
;; 3. aka (http://aka-cs-blog.blogspot.com/): さらにCL臭く。足回りの整備を実施。REPL上での使い勝手を強化。副作用って何?という感じの仕立て。 | |
;; 4. quek (http://read-eval-print.blogspot.com/): 辞書ファイルがない状態からでも (hige:pin) できるようにしました。 | |
;; 5. 佐野匡俊 (http://twitter.com/snmsts): ABCLとswingでぬるめのUIを。他の処理系での動作は鐚一文変えるつもりなく結果的に#+/-ABCLまみれ。 | |
;; 6. 備前達矢(び) (http://twitter.com/bizenn): SBCL+Mac OS X縛りで出題単語を読み上げ。sayコマンドを叩くだけという手抜きっぷり。 | |
;; 7. naoya_t (http://blog.livedoor.jp/naoya_t/): 辞書からの単語検索 (hige:pan) を実装。 | |
;; 8. masatoi (http://d.hatena.ne.jp/masatoi/): n択問題(hige:pen)を実装.英単語から意味を問うのと意味から英単語を問うのと選べる.named-let使いまくり. | |
;; 9. cranebird (http://d.hatena.ne.jp/cranebird/): CL と言えばマルチパラダイムなので CLOS を。with-系のマクロを追加。 | |
;; 10. smeghead (http://d.hatena.ne.jp/smeghead/): 単語のスコアを導入した。問題の単語表示時にスコアを表示するようにした。単語の一覧表示(hige:pun)にキーワード引数 score-thresholdを追加。 | |
;; 11. NANRI (http://raido.sakura.ne.jp/southly/rn/): デバッグとちょっとした整理。あと (asdf:oos 'asdf:load-op :scheme_baton) でロードできるようにした。 | |
;; 12. 佐野匡俊 (http://twitter.com/snmsts): 備前さんの変更がSBCL+OS Xなのでread-time conditionalizationをらしく修正。これがschemeに無いらしいのが残念。 | |
;; 13. making (http://blog.ik.am): 辞書ファイルをhttp経由で取得できるようにした。要drakma。 | |
;; 14. 深町英太郎 (http://e-arrows.sakura.ne.jp/): 単語登録時に意味を空にした際にGoogle翻訳の結果を登録できるようにした。要cl-ppcre。 | |
;; 15. kurohuku(@sirohuku) (http://kurohuku.blogspot.com/): Gray Streamを使ってpon,pen時に回答のログをとるようにした。要trivial-gray-streams。 | |
;; 16. kosh (http://lisperblog.blogspot.com/): 空のエントリを登録しないようにした(add empty-entry-p), ログファイルもディレクトリがない場合は作成するように | |
;; ================================================================================================================================================= | |
;; これより下がコードとその説明 - 変更・削除歓迎 | |
;; ================================================================================================================================================= | |
;; ■英単語暗記補助ツールです | |
;; 起動すると辞書ファイルから単語が表示されるので意味を頭で考えます。改行を入力すると答えが表示されます。 (y/n) を聞かれるので正解なら y を押してください。 | |
;; 間違った単語は辞書ファイルに記録され次回出題されます。 | |
;; | |
;; ■動作方法 | |
;; ANSI Common Lisp で動作します。 | |
;; (hige:pin) ; 辞書に英単語を登録 | |
;; (hige:pin :uri "http://gist.github.com/273424.txt") ; http経由で辞書に登録 | |
;; (hige:pon) ; 英単語ゲームの開始 | |
;; (hige:pun) ; 辞書の一覧表示 | |
;; (hige:pun :score-threshold 10) ; 辞書の一覧表示(スコアが10以下の単語のみを表示する) | |
;; (hige:pan) ; 辞書から単語を検索 | |
;; (hige:pen) ; 英単語ゲームの開始 (三択問題) | |
;; (hige:pen :n-choice 5 :meaning? t) ; (五択問題で意味に対応する英単語を選ぶ) | |
;; | |
;; オリジナルはシェルスクリプトとして動作しますが、CL版は現状REPLでの対話です。 | |
;; ※R6RS Schemeで書かれたオリジナル版 | |
