Multiple git repositories with same base directory

I have two codebases, called a and b. Project a provides a common infrastructure that project b relies upon. However, all of the code for for project b is underneath the directory structure for project a. Here's an example:

a File0.cs
a Assets/Core/File1.cs
b Assets/Extension/File2.cs

So projecta provides File0.cs and File1.cs and owns the Assets folder. Project b only provides File2.cs

Does git support this directory structure? If so, how?

Thanks

Yes, it does. It is called "submodule" in git jargon. You can get help on it with git submodule --help.

Though, it is not seen as very good style to depend on submodules, if possible, use various package/dependency managers like pip, gem, npm, bower etc.

What you'er looking for is called a "Submodule":

6.6 Git Tools - Submodules

Basically you can tell git that a directory inside your repository is actually a separate repository, tracked elsewhere. This works at the directory level, not the file level.

From there, assigning individual files to a specific repository's directory is just a matter of creating symlinks.

myapp/
myapp/submodule/                    <-- submodule repository
myapp/submodule/foo.c               <-- shared file
myapp/foo.c -> submodule/foo.c      <-- shared file reference in parent dir

Windows support symlinks on NTFS, but it doesn't advertise the fact, making them slightly more difficult to deal with.
