ローカル用ブックマーク
http://d.hatena.ne.jp/hyuki/20071220#bookmark
乗り遅れすぎですが、自分でもこういうの欲しかったので、作ってみました。とりあえず試作品。指定したURLのファイルしか取ってきません。文字コードによっては題名がちゃんと読めません。
簡易Webサーバを立てる方式にしてます。Javaで書きました。非常に書きづらいと分かっていたものの、自分で手っ取り早くサーバを書けるのがJavaしか無かったので。（Rubyだと、WEBrickというのを使えばできそうですね。）
起動は
$ java Bukma 80
で、ポート番号は可変になってます。※セキュリティ注意してください。
javascript:window.location='http://localhost:80/edit'
を設定。ここもポートを上のに合わせて。
ブックマークレットをたたくと、画像の上の画面が出ます。入力して送信すると、下の一覧が出ます。
リストはローカルのURLで読み直して使うようにしています。
