■ [arc] Arc 3.1はいかにしてset-car!を実装したか

• http://arclanguage.com/item?id=10254

pg「MzSchemeの最新版はset-car!がないから古いやつを入れてね」
  ↓
pg「パッチ貰ったんで最新のMzSchemeでも動くようになったよ」

えっ、それってset-car!するたびにリストを作り直すってこと？と思ってパッチを見たら：

+(define (set-ca/dr! offset who p x)
+  (if (pair? p)
+    (let ([p* (get-ptr)])
+      (ptr-set! p* _scheme p)
+      (ptr-set! (ptr-ref p* _pointer 0) _scheme offset x))
+    (raise-type-error who "pair" p)))

ptr-set!ってなんだｗｗｗ

■ [ruby-station] Windows対応

2時間ほど試行錯誤したあげく、「Open3がない」というオチ。今回は諦めるか…。

RubyStationで外部プロセスを起動したい場面は2つある。

1. アプリケーションの起動。stdout, stderrは取れなくてもいい(起動に失敗した時のことを考えると取れてほしいけど…)。できれば終了を検知したい。
2. gemコマンドの起動(インストール、アンインストール)。stdout, stderrが必須、できればリアルタイムに。終了の検知は必須。

で、Rubyでどうやるかというと：

• 前者
  • Process.spawn (○windows対応 ×1.9のみ)
  • Thread + system (○windows対応, 1.8でも)
• 後者
  • Popen3 (×windows非対応)
  • PTY (○リアルタイム、×windows非対応)
  • そもそもgemコマンドを使うのをやめる (GemのAPIを叩く) (○リアルタイム, windows対応 △gemのバージョン間の差異を踏まないか)

という感じ。

さて、「windowsで」「1.8で」「起動したプロセスのstderrへの書き込みを取得する方法」ってあるのかな。
