翻訳作業中に知ったんだけど，iSCSIはまだVMware CertifiedじゃなかったのかYO!!
このファームで安定するのかなぁ〜

Jaws CMSのメッセージカタログの差分を出す

PHP

翻訳対象の英語メッセージがどう更新されたのか，リポジトリーを元に管理をします．
時々やってるんですが，基本的にリポジトリーベースで管理をしないと差分追跡ができなくて．
Serendipity Weblogの場合はこういうのを用意して作業しています．

http://elf.no-ip.org/php/dev/s9y/trans-info/s9y-trunk/ja/status/

大体こういうのはEN-Revisionというキーワードを日本語訳のファイルに付与して英語ファイルとの差分管理をします．
PHPでは古のアプローチでドキュメント化されたものとしてはこの辺．

http://doc.php.net/php/ar/dochowto/translation-revtrack.php
http://wiki.php.net/doc/translations サンプルコードは高木さんだし(苦笑

今回題材にしたJaws CMSの場合はこんな感じの手順で作業をしていました．

元ファイルのリビジョン番号やチェンジセットを入手する (ex: svn info en.php)
その情報を翻訳ファイルに記録する (ex: // EN-Revision: foo)
公式サイトに渡すなり自分でコミットするなりする

っで，公式開発チームがどうしてもEN-Revisionを消すので近いうちにちゃんと説明しようかなと．
とりあえずワンライナーで差分ファイルを作成するものを作ってみた．

$ for CATEGORY in gadgets plugins; do pushd ${CATEGORY} > /dev/null; for COMPONENT in `find . -maxdepth 1 -mindepth 1 -type d ! -name .svn | sed 's@^\./@@g'`; do pushd ${COMPONENT}/languages > /dev/null; for CHECK_LANG in ja; do EN_REVISION=`grep EN-Revision ${CHECK_LANG}.php | sed 's@^.*EN-Revision: \([0-9]*\)@\1@g'`; echo -n "Check ${CATEGORY}/${COMPONENT}'s en.php between r${EN_REVISION} and HEAD, for ${CHECK_LANG}.php ... "; svn diff -r ${EN_REVISION} en.php > ${CHECK_LANG}.diff; echo "done."; done; popd > /dev/null; done; popd > /dev/null; done

解いてみた．今回は少し長い．

$ for CATEGORY in gadgets plugins
  do
    pushd ${CATEGORY} > /dev/null
    for COMPONENT in `find . -maxdepth 1 -mindepth 1 -type d ! -name .svn | sed 's@^\./@@g'`
    do
      pushd ${COMPONENT}/languages > /dev/null
      for CHECK_LANG in ja
      do
        EN_REVISION=`grep EN-Revision ${CHECK_LANG}.php | sed 's@^.*EN-Revision: \([0-9]*\)@\1@g'`
        echo -n "Check ${CATEGORY}/${COMPONENT}'s en.php between r${EN_REVISION} and HEAD, for ${CHECK_LANG}.php ... "
        svn diff -r ${EN_REVISION} en.php > ${CHECK_LANG}.diff
        echo "done."
      done
      popd > /dev/null
    done
  popd > /dev/null
  done

解いてみると手抜きでjaしか対象にしていなかった(苦笑

「Hadoopを使う」というだけだとした場合((ほとんどの場合はそうだと思うけど)，この書籍があれば補足的にウェブで調べたり勉強会に参加したり試したりで委員じゃないだろうか?
持ち運ぶ気と必要な部分を読破する気力さえ会えれば他の入門書は(あるの?)もういらない．
一番のネックはイニシャルの投資(4800円)と容積，重量でしょうかね…

#関係ないけど1月末出版らしいんだけどすでにamazonでの中古が9000円を超えている(笑
