Extract part of a git repository?

Question

Assume my git repository has the following structure:

/.git /Project /Project/SubProject-0 /Project/SubProject-1 /Project/SubProject-2 

and the repository has quite some commits. Now one of the subprojects (SubProject-0) grows pretty big, and I want to take SubProject-0 out and set it up as a standalone project. Is it possible to extract all the commit history involving SubProject-0 from the parent git repository and move it to a new one?

Answer 1

See http://git-scm.com/docs/git-filter-branch

I think you need something like

git filter-branch --subdirectory-filter Project/SubProject-0 --prune-empty -- --all 

in a clone of the repository.
