■ るびま #12 の添削

るびま 12 月号、添削記事は筆者の一身上の都合によりお休みです。 すんまそん。どうやら運がよくなかったらしいです。

と思ったら、一月が最初から休みの月だったので二ヶ月あいちゃうのね。 まあ、そのころならだいたい原稿も書き終わって気楽に書ける

わけないんだよな。前科からして。

■ YARV

とりあえず YARV ビルド……

% ./build.sh all
zsh: 1906 segmentation fault (core dumped)  ./build.sh all

なぜここで sh が落ちる―――！

■ 忘れる病

Ruby ばっか書いてると C でセミコロンを忘れるというのは常識だが、 今日は Haskell / sh ばっかり書いてたために Ruby で引数間のカンマを忘れた。 文字列二つだと連結されちゃって文法エラーにならないという例のやつだ。

sh の core は見なかったことにして Ruby に逃げた
