dRuby + Rindaでriを15倍速くするfastri - 角谷HTML化計画(2006-11-08)

■1 dRuby + Rindaでriを15倍速くするfastri

fastriはebanさんのri検索結果キャッシュスクリプトにインスパイアされたらしい。仕組みはdRuby + Rinda。riサーバ(fastri-server)にクライアント(friコマンド)からタプルを投げちゃう。15倍ぐらい速くなる。かっこいい。

$ time ri -T Enumerable#inject
  0.57s user 0.43s system 82% cpu 1.208 total

$ time fri Enumerable#inject
  0.03s user 0.01s system 49% cpu 0.082 total

sheepmanさんのirbでのri補完っぽくfriを組み込むエントリもあったので、マネしてみた。ストレスなくirbからriを引けて嬉しい。

検索結果にほんのり色もつく。

リポジトリがdarcsだと書いてあったので、私はTiger用のdmgを使って取ってきたけど(最初MacPortsでdarcsを入れようとしたらvariantsを指定してもghc6.6でコケたので即あきらめた)、リポジトリを追いかけるのでなければhttpだからwgetとかcurlとかでも取ってきてインストールできるんじゃないでしょうか。インストールはsetup.rb(少なくとも私は)。

fastri-serverをOSXのログイン時に起動させる

最初はStartupItemsを使おうと思ったんだけど、自分ではうまくやれなかった(SystemStarterでは起動するんだけど自動起動してくれない……)。id:moroの人のアドバイスに従って、launchdを使ってみた。plistの編集にはProperty List Editorを使った。

~/Library/LaunchAgents/fastri-server.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
                       "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>fastri-server</string>
  <key>OnDemand</key>
  <false/>
  <key>Program</key>
  <string>/Users/shintaro/bin/fastri-server</string>
</dict>
</plist>

ログイン時の起動でいいや、と思ったので~/Library/LaunchAgentsに置いてます。launchdについては『Professional Mac OS X』が参考になる。plistについてとか詳しすぎる。
