WiLiKi:静的HTMLへの変換
WiLiKi-0.5でフォーマット関係のAPIを変更したので、このままでは 動かなくなってしまいました。 ぼちぼち直します。--Shiro
WiLiKiのデータベースからドキュメントを吸い出して、静的なHTMLページ群へと 変換するスクリプトです。
まだ、wilikiのAPIが整備されていないため、wiliki本体の関数を再定義するとか いろいろ怪しいことをやっていますが、wiliki-0.5までにはそのへんを綺麗に する予定です。
標準添付のマクロだけなら多分ちゃんと動きますが、 wilikiページ内への文書のリンクを直接生成するマクロを使っている場合には うまく変換できないと思います。
