アクセスログなどに残されたアクセスしてきたユーザーエージェント（User-Agent）をもとにブラウザやらOSについて一括で大量に解析したい必要があったので、いろいろ探していたら woothee-java が良い感じだったのでプチツールを書いてみました。
どれほどの需要があるかわかりませんが、意外と便利だったので自分のメモ代わりに。
コード
lookupbrowser.groovy
@Grab("is.tagomor.woothee:woothee-java:1.4.0")
import is.tagomor.woothee.Classifier
println '"UA","Category","OS","Vender","Browser","Version"'
System.in.eachLine { line ->
String userAgent = line.replaceAll('\\+', ' ');
Map info = Classifier.parse(userAgent)
println "\"$userAgent\",\"$info.category\",\"$info.os\",\"$info.vendor\",\"$info.name\",\"$info.version\""
}
実行例
$ cat ualist.txt | groovy lookupbrowser.groovy

標準入力にユーザーエージェントの文字列を丸々流し込めば、CSV形式で出力してくれます。
Excel等で読み込むと、こんな感じのテーブルとして見えます。

所感
こういうプチツールを作るのに、豊富なライブラリを手軽に使えるgroovy便利過ぎ。あまり構文やら型を意識しなくてもJavaScript感覚で書けるのがいいですね。
結果として1,000パターン程度読み込ませて認識できなかったのは、ボットやアタックツール系のUAらしくないものくらいで精度の良さに驚いた。マイナーなブラウザやモバイル端末のOSまで認識してくれる woothee-java 様様でした。
