Generate diff with git-diff and use in patches field of packages

[Léo Le Bouter]

Hello!

While patching packages for security issues, I often am needing to get
some patches from git repos because upstream does not make releases.

Including patch in "patches" directory etc. is a bit troublesome, I
would rather have some Scheme code do this with: upstream git url,
commit selector range or not, with hash checking like origins.

Is that possible?

Thank you
