Today I discussed with Dave Syer about some improvements in Spring Integration, which I had sandboxed in my messy github repository. A sparse checkout would be convenient, but we both didn't know how to do it. I even thought git didn't support it, but boy was I wrong!
iwein:si-sandbox$ git init
Initialized empty Git repository in /tmp/si-sandbox/.git/
(master) iwein:si-sandbox$ git config core.sparsecheckout true
(master) iwein:si-sandbox$ echo message-store/ >> .git/info/sparse-checkout
(master) iwein:si-sandbox$ git remote add origin git://github.com/iwein/Spring-Integration-Sandbox.git
(master) iwein:si-sandbox$ git pull origin master
The important thing to remember is that this also works with git-clone. Your index will still have everything, just your checkout (working copy generated from the index) will not. This is a big difference with svn sparse directories, and as usual it's an improvement.
