support for --git-dir

[rande]

Hello,

It will be great to support the --git-dir feature. : http://stackoverflow.com/questions/672655/relocating-the-git-folder

It is like adding into the Repository class a getGitDir() which return . by default and use it everywhere the script runs a git command.

Sounds great, but before doing this, I would like to refactor the way processes are executed: using Symfony Process component.

Also, shell calls should be moved to the repository object, to factor calls and add such global arguments.

Hey @rande, great news for you: it's now possible to use git-dir option and also work-tree (for the working directory).

You need to pass it to the constructor:

$repo = new Repository("/path/to/.git", "/path/to/working-tree");
$repo->getWorkingCopy()->checkout("master");

You can also run any command using run method on Repository.

It's now part of master on gitlib.

Enjoy!
