rd2 が動かなくなった

ひさしぶりに RT を使った RD ファイルに rd2 (rdrt2) をかけたらこんなエラーメッセージが出て失敗した。

$ rdrt2 -r rd/rd2html-ext-lib --out-code=utf8 --native-inline --ref-extension aaa.rd > aaa.html

調べてみたら、どうも rd2 が optparse の古いあるいは隠し機能を使ってるみたいだった。こんな風に変えてみた。

     with_part.push([part, filter || part])
     unless include_path.index(RD::RDTree.tmp_dir)
       include_path.push(RD::RDTree.tmp_dir)

optparse も Ruby もあまり詳しくないからもしかしたら適切な直し方じゃないかも知れないけど、一応動いたみたい。

ん、Firefox で見ると右の方が切れて見えるなぁ。デザイン変えた方がいいのかな。コピペするのは大丈夫みたいだけど。
