Rejecting whitespace-only changes at github

Is there some tool or online-service which can check patches if they contain white-space-only changes and all test-wrapping changes?

I don't think you can run code on GitHub like that. You can write a bot that listens for new pull requests, and comments on them, but you have to find your own place to run that bot.

In coreboot we try to check for whitespace errors before committing. Of course a pre-commit hook is the way to go, but unfortunately it is not so simple (at least for me) as the following requirements exist.

  1. Only the files actually committed should be checked. That means running git commit -a, abort that and then running git commit some/file should only check some/file for whitespace errors.

  2. There are certain files that are allowed to have whitespace errors. In our case these are *.patch and *.diff files which by design seem to contain whitespace error.

Currently the whole tree is checked, which takes a lot of time. I tried to come up with a patch, but failed so far. Best would be to have

$ git diff --check --only-committed-files --exclude "*patch$"

where I could not find a way for the last to switches.

Currently, I would use

$ git diff-index --cached --name-only $against -- | grep -v patch$

and pass that list to some whitespace check program. Unfortunately that still does not fulfill the first requirement. What am I missing to solve this elegantly?

I was learning to user git-bash and github. As part of tutorial we were asked to set username & password through git-bash command line and create an account in github. But since I already set the email through gitbash global config, I am not allowed to create account or create a password for my account .

Please let me know how can I create a account in github or delete the entry to start fresh.
