Prerequisites

Create a git pre commit hook and give it permission to execute:

touch .git/hooks/pre-commit && chmod +x .git/hooks/pre-commit

Add the following bash script to the hook:

#!/bin/sh

standardrb --fix --format progress $(git diff --name-only --diff-filter=ACMRTUXB master | grep -E "(.rb$)")

Very helpful, thanks! but heads up -- I had to update to | grep -E "(\.rb$)" to get just "*.rb" without *.erb.
