先週末に iTunes のアートワークがあまりにも入ってないことに気づいて Cover Flow がかなりしょぼいことになってた。アートワークを Amazon やらから取得するツールはたくさんあるのだけど解像度が高い画像をとれないのがちょっと。
そこで Xcode を使ってアプリでも作るかと思ったけど C++ は書けても Objective-C なんぞは無理。じゃあ前から気になっていた AppleScript で、ということで簡単に。
基本は Amazon ESC 使って Large サイズのサムネイルを取得してそれを iTunes にアートワークに追加するという流れ。アートワーク追加がまだうまくいってないのでとりあえずはサムネイル取得とそれを表示までやってみた。
Amazon からのサムネイル取得は以下のソースを思い切り流用。アクセスキーを個人的に持ってなかったので旧来のサブスクリプションIDを使用するように変更。
ちゃらんぽらん : Amazon Web サービス
Xcode でダウンロード開始する clicked アクションを持ったボタンと ImageView(以下のソースだと "imageFrame" という名前) を配置。そして以下のようなスクリプトを書いてビルドするとOK。
property tmpFolder : path to temporary items folder from user domain
property tmpXMLFile : POSIX path of ((tmpFolder as Unicode text) & "request.xml")
property tmpPNGFile : POSIX path of ((tmpFolder as Unicode text) & "request.png")
property tmpJPGFile : POSIX path of ((tmpFolder as Unicode text) & "request.jpg")
property baseurl : "http://webservices.amazon.co.jp/onca/xml"
property service : "AWSECommerceService"
--property accesskey : " " -- ここにアクセスキー
property subscriptionId : " " -- ここにサブスクリプション ID
property associateid : "xxxxxxxx-22" -- ここにアソシエイト ID
property operation : "ItemSearch"
property searchIndex : "Music"
property responsegroup : "Request,Small,Images"
property AWSVersion : "2006-05-17"
property pagenumber : "1"
property sort : "salesrank"
property targetPathMac : ""
property targetPathPosix : ""

簡単であるが、やや癖のある AppleScript。今後使っていくことも多そうだ。Mac のアプリケーション機能をすぐに引き出せるところが魅力的。
