取得した候補の文字列から、「anythingの候補として表示させる部分」と「選択後にコマンドによって実行される部分」とを分断することができます。その処理を行う関数を行うのが、 candidate-transformer ということになる…らしい:

candidate-transformer (オプション)
< / dt >
< dd >
source から補完リストが作成された際に引数を一つとって呼び出される関数である。その引数は source から取得された候補のリストである。実際の補完に用いられる変換済み候補のリストを返さなければならない。< br / > この要素は候補のリストからアイテムを変更したり、取り除いたりするために用いることができる。< br / > この関数は「(表示文字列 . 実際の文字列)」という対のリストを返すことで、候補を修正することができる。この場合、「表示文字列」は Anything バッファーで表示されるが、「実際の文字列」は候補が選択されたときの action の引数に用いられる。このことによって、例えば候補があまりに長ければより読みやすくすることができるし、他の候補と共通の部分があり表示のために短縮した文字列に安全に置換できるようになる。< br / > 注意: 仮に「(表示文字列 . 実際の文字列)」という形式が用いられた場合、パターンマッチは表示文字列で行われ、実際の値では実施されない。

というわけで、実際に使ってみました。

使用する外部スクリプト
< / h4 >
< p >
前回と同じようにflickrから情報を引き出すスクリプトを用いますが、ブログに投稿できるようなサイズの画像へのリンクも一緒に取得させています。
< / p >
< p >
ちなみにこのスクリプトを使用する際には、flickrからapi_keyを取得し、「xxx」の部分を取得したapi_keyに変更してください。
