Git: send-email without commit

I ha开发者_开发知识库ve a project where I made changes, and want to send them to another user, using git send-email feature.

I found that it works by sending patches (created by git format-patch of each commit).

Is it able to send just diff's ? I don't want to commit first, and then send the patch.

Does git format-patch or maybe send-email have some parameter to just do that quickly?

Thanks in advance.

It turns out not to be possible. So I commited and tried to send-email it, which throws an error

Command unknown: 'AUTH' at /usr/lib/git-core/git-send-email

This error is related to my smtp-server not supporting authentication.

To solve this, I commented the line in my .gitconfig where it says smtpuser, so that it doesn't pass any user or password to git. Then, the email gets sent without a problem.

But I still think that should have an option to use send-email feature, sending a patch without having to commit it first.
