Now unity 5.5.0 have Perforce and Plastic SCM integration, that’s a step in the right direction, but no git support or planning in doing it at least is not listed in the roadmap (https://unity3d.com/pt/unity/roadmap).
So yesterday I begin a port of the libgit2sharp to work with unity, here is my fork https://github.com/lassade/libgit2sharp. For now the project builds, tests passes (except one, about formating an exception message) and is working great with Unity as far I can tell.
But here is the problem: There is any way of creating something similar to file integration in the project window like we have with Perforce and Plastic SCM? With all the symbols telling file changed, conflict, file added and etc.
Current I want to create a system that is intuitive so the artists can resolve problems without the need to go the command line. And I do not want recreate a project window just to do that.
Edit:
My friend just point me out that the unity uses its on window for mange files under version control. Guess I will have to keep working in my on version of this windown.
