Diggの新着を表示するApricot用アドオン

Diggの新着を表示するApricot用アドオンをPythonで書いてみました。

サムネイル画像はもちろん、Diggの「票(digg)」の数も表示することが出来ます。

ちなみに、このDiggの新着を表示する際はRSSの解析結果をApricotに渡していますが、通常のRSSの場合はOPMLファイルに追加して対応できます。しかし、Diggの「票(digg)」のような特殊なタグがRSSに含まれている場合はアドオンのような形で対応させています。

Digg

下記のスクリプトをUTF-8で保存して、Scriptsフォルダに入れればApricotのキャラクターが新着を喋るようになります。
