dvcs - Git Submodule to a subfolder

Question

In svn you can link a repository to any folder in another svn repository. I'm wondering if there is a similar feature for git? Basically I want a git submodule inside my repository, but I want the submodule to be a pointer to a subfolder of another git repository, not the whole repository. Is this possible?

Answer 1

Git does not support partial checkouts, so the submodule must point to a complete repository.

This thread on the Git mail list provides some background information.

This article from Panther Software offers some insight from someone else trying to accomplish a similar goal (i.e. replicate svn:externals using Git).

If both projects are under your control, then I suggest you isolate the "subfolder" that you interested in to its own standalone repo. Then both projects can create submodules that link to it.
