Can I show the git diff status on a per-line basis?

Question

I'd like to be able to see which lines in my file have been edited relative to the current git head, is there any way I can do this?

In particular, I'd like to be able to tell if a line was added or modified as I would by looking at the git diff.

Answer 1

gitgutter and signify are two plugins I know of which provide this sort of functionality. When a buffer is saved, the sign column is updated to show where lines have been added/modified/deleted.

gitgutter is Git specific, while signify supports multiple version control systems.
