■ Haskell 製 Wiki clone : LazyLines

Haskell で Wiki 書いた → http://i.loveruby.net/ll/

思ったこと

• 全然気付かなかったが BitChannel の ReverseLink はとても便利だったらしい
• 検索もないと辛い

って Haskell じゃなくて Wiki の話かよ。

■ LazyLines (2)

いちおうソースコードの入手方法だけはこっちにも書いとくか。

% cvs -d :pserver:anonymous@cvs.loveruby.net:/src co lazylines

パッケージはどんどんバージョン上がるんで書きません。

■ YARV

socket.so もあるみたいだから YARV で BitChannel を試して (落として) みよう。

と思って make ext したら落ちた。話が早いな。

GC の途中かあ。 本家みたく、ひたすら GC しまくるやつを入れてみるべきかな。

■ YARV (2)

うーん、gcc -O0 では起こらない……。 どうしようかな。

(11:29)

■ LazyLines (3)

本当は TwoTailって名前にしようかと思ったんだよ。 その前は TwinTail を考えたんだけど、 「ついんて〜る」って 2ch ブラウザがあるから。

あ……今号ほとんど読んでねーや。 編集担当らしい YARV だけ読もう。
