Trac / レポジトリ生成用 CGI を Mercurial 対応に
以前（⇒ レポジトリ・trac 生成 CGI を作る - daily dayflower）作ったレポジトリ等生成ウェブインタフェースを，Mercurial にも対応するように書き換えました。といっても Trac 0.11b2 用にしてしまったので，0.10 では動きません。一応注釈はいれておいたんで，がんばれば 0.10 用にもできますけど((ほんとは try:〜except ImportError: で囲めばいいんですけどね))。
最初は trac.env.Environment を直接操作してたんですが，デフォルト Wiki ページの生成部分がちょっとひどいことになりそうだったので，以前と同じように標準出力をトラップする形にしてます。このへん（admin 用インタフェース）ももうちょっと整備してほしいところですね。
2008/03/05 追記: デフォルトの Milestone 等がうっとおしいので削除しておくようにしました。
LoadModule wsgi_module modules/mod_wsgi.so WSGIScriptAlias /trac/create /var/www/app/trac_builder.wsgi <Directory /www/main/app> WSGIApplicationGroup %{GLOBAL} SetEnv TracEnvParentDir "/var/www/trac" SetEnv TracReposParentDir "/var/www/repos" Order deny,allow Allow from all </Directory>
みたいな使い方。以前と異なりシングルファイル化したので，mod_python とかの場合は，適宜パッケージとしてインストールしてください。個人的に mod_wsgi に移行してしまったので mod_python ではテストしてません。
