Can you submit a PR on symfony/symfony-docs to update the documentation and reference it here before I merge? Thanks.

---------------------------------------------------------------------------

I've already done it in PR1527.

Actually, to be BC in PHPUnit when switching to Finder (this feature is the reason why the switch was reverted in 3.7), they will need the support of the glob syntax. Should it be supported directly in the Finder or should we consider that PHPUnit will have to put the code converting globs to regexes themselves before calling the finder ?

---------------------------------------------------------------------------

by fabpot at 2012-09-23T13:15:08Z

@stof what about supporting globs/patterns for the `in()` method?

---------------------------------------------------------------------------

by stof at 2012-09-23T13:38:00Z

yeah, this could be a good idea too

---------------------------------------------------------------------------

Supporting globs in `path(), notPath()` methods is trivial: we have `Glob::toRegex()`. The only thing to do is to convert (when necessary) parameter sent to `path(), notPath()`.

@gajdaw can you update this PR with the glob support and rebase it ?

---------------------------------------------------------------------------

by fabpot at 2012-10-29T11:20:55Z

@gajdaw You also need to rebase and update the new adapters accordingly. Maybe @jfsimon can help.

With pleasure! @gajdaw let me know if I can do anything.

I have moved `->path()` and `->notPath()` methods to `PhpAdapter`.

This implementation passes all the tests on Windows, but Travis reports failures.

I think that similar methods should be implemented for `GnuFindAdapter`.

@jfsimon What do you think?

---------------------------------------------------------------------------

by jfsimon at 2012-10-29T17:03:36Z

@gajdaw Travis says class 'Symfony\Component\HttpKernel\Exception\InternalServerErrorHttpException' not found in /home/travis/builds/symfony/symfony/src/Symfony/Component/HttpKernel/Tests/Exception/FlattenExceptionTest.php on line 83. This is weird.

And yes, `AdapterInterface` and `GnuFindAdapter` should be updated too. I can work on it if you like.

---------------------------------------------------------------------------

by fabpot at 2012-10-29T17:07:46Z

I've just fixed the unit tests

---------------------------------------------------------------------------

by gajdaw at 2012-10-29T17:25:43Z

@jfsimon Can implement `path(), notPath()` for `GnuFindAdapter`? I have no time to analyse Gnu's `find` command at the moment. Thanks!

---------------------------------------------------------------------------

by jfsimon at 2012-10-29T17:30:13Z

@gajdaw okay.

---------------------------------------------------------------------------

by jfsimon at 2012-10-29T19:05:26Z

@gajdaw work complete! I cant make a PR on your repos :-/ Could you merge my repos https://github.com/jfsimon/symfony/tree/component_finder_path_notPath please? Or maybe could I post a new PR on symfony/master.

---------------------------------------------------------------------------

by gajdaw at 2012-10-30T05:34:17Z

@jfsimon I have pulled your changes. I don't know wheather you should post a new PR.
