git-inject-tarball

Hi,

In the Everyday commands[1], there is an example of of extracting a tarball and then working with it. I'm finding that I'm doing this fairly often -- I was just wondering if anyone had anything like a 'git-inject-tarball' script they'd written up.

Thanks, Anand

Something like this?

-- snip -- #!/bin/sh

TARFILE="$1" test -z "$TARFILE" && TARFILE=-

git-ls-files -z | xargs -0 rm tar xvf "$TARFILE" | xargs git add git-update-index --remove $(git-ls-files) -- snap --

Notes:
	- this updates the index to match the given tarfile, you still 
	  have to commit yourself
	- it does not handle compressed tarfiles (you have to do something
	  like "cat bla.tar.gz | gzip -d | sh git-untar.sh")
	- it does not remove empty directories (i.e. if the current index 
	  contains a file "a/b", and the tarfile does not, and the
	  directory "a" is now empty, this is not handled)
	- usually, tarfiles contain files inside a subdirectory. There is
	  no facility to strip the subdirectory

Well, the most important thing for such a tool IMO would be that it wouldn't overwrite any uncommitted changes, so it's not as trivial as it seems.

Ah, but that's easy:

	test -z "$(git-diff-index --name-only HEAD)" || exit 1

(This is just the idea; you should also output an error message.)
