w3mでもFastladderが読みたい！

w3mでもFastladderが読みたい。でも、touch用のインタフェースを使おうにも、w3mはFastladderを相当嫌って

と言われて、ログインすらできない。参考。
w3mにパッチをあててこれを回避したりするのはなんか悔しいから、local cgiでFastladder用のインタフェースを実現してみた。ちょっと手直しをすればLivedoor readerでも使えるかもしれない。

ただ、RubyのWWW::Mechanizeでcookieを保存する方法がよくわからなくて、毎回ログインしているので、動作がちょっともたつく。keyとvalueから適当なクッキーを生成して、Mechanizeに食わせることができるといいんだけど・・・。

あとw3mのlocal cgi機能を使って、w3m本体の制御をしているから、普通のCGIとしては公開できない。

fastladder.rb

Fastladder APIのインタフェース。ほかのやつにも使えるかもしれない。

pin.cgi

ピン立て用。ピンの一覧と、クリアができる。
