Extension versions

Heya, It appears that many extensions do not expose proper version information. Here an abstract of the various things I found using the following script: $ for i in php -m; do php --re $i | grep "$i version"; done curl <no_version> date 5.4.0 dom 20031129 mysqlnd mysqlnd 5.0.10 - 20111026 - $Revision: 323634 $ PDO 1.0.4dev Reflection $Revision: 321634 $ xdebug 2.2.0rc1 As you see it goes from no version at all to proper versions, passing by svn revisions, dates, or a mix of all. In Composer [1] we try to parse all that using ReflectionExtension, to allow people to require some specific version of an extension if they want. Obviously this doesn't work very well when no version or some random revision number is provided. Is there any other way I overlooked to get more version info? If not, can this at least be improved in the future? [1] http://getcomposer.org/ Cheers -- Jordi Boggiano @seldaek - http://nelm.io/jordi
