Hi,

It seems like the --summary option only works in combination --stat.

It doesn't seem to work if I use it by itself, nor in combination with --name-status or --num-stat. And depending on the order, it either does nothing, or causes a usage note.

Is this intentional? If so, could it be reconsidered? At the very least in combination with --name-status and by itself, I can kind of understand it not working with --numstat

Ive tested with two gits, and it seems to be the same in both:

git version 1.7.2.1 and git version 1.7.3.2.168.gd6b63

Cheers, yves

It is tricky, but as you noticed --summary is not actually about the diffstat. --summary affects the output summarizing new files and renamed files.

Example:

	$ git diff --summary v1.7.2..v1.7.3
	delete mode 100644 Documentation/RelNotes-1.5.0.1.txt
	delete mode 100644 Documentation/RelNotes-1.5.0.2.txt
	[...]

There is an 'm' missing here. :)

Hope that helps, Jonathan

Thanks for your reply. It turns out that was a mis-paste. I tried both splelings of summary. ;-)

And none of them produce output.

$ git diff --summary HEAD^..HEAD $ git diff --summary HEAD^^..HEAD $ git diff --summary HEAD..HEAD^ $ git diff --summary HEAD^

So why does it work for you but not for me?

Ah. Not enough coffee. It "doesnt work" because I am not adding or renaming a file here?
