You can also set this in your ~/.gitconfig

whitespace = trailing-space,space-before-tab

ohh word? someone at work is getting an email yo!

pivot says you are wrong

LOL! In the future I will keep my opinions to myself.

Try it for a few weeks and see if you still find yourself needing such a script. :D

We used to do shit like that back in the day as a part of our test suite. https://gist.github.com/03e30c6f12dbb6c96601

to my understanding this only throws warning / stops you from committing, but it doesn't actually strip the whitespace?

Yup,

It appears you guys are right, it just ignores whitespace added when diff'd. I guess my team at the time just started pruning the trailing whitespace we were seeing. :)
