EDIT: mix format has been updated now to only format the files which have changed so the workaround with git diff is no longer needed.
Running mix format on larger projectes can be very slow as every file is being checked.
mix format can be given a list of files such as mix format user.ex api.ex finance.ex so
that it formats only the given files.
You can do this by running mix format $(git diff --name-only).
