Elixir Git pre-commit hooks

Part of my Elixir development flow is to run certain checks and test before pushing changes to the remote. The main thing that I want is to make sure my code is following the standard Elixir formating with mix format.

We can easily do this with a pre-commit hook:

#!/bin/bash
cd `git rev-parse --show-toplevel`
mix format --check-formatted
if [ $? == 1 ]; then
   echo "commit failed due to format issues..."
   exit 1
fi
