Git Post-Commit Formatter
Working in languages like Elixir and Rust is fun for many reasons. But one of
my favorite features is the formatter. Elixir (after 1.4) comes with a
formatter which is well integrated with mix and can be called using
mix format. At first, the idea of a machine changing the code that I wrote
for my project didn’t sound very exciting to me. But working in a team
environment and being able to configure the formatter based on what best
practices a project follows, made it all worth it. Moreover, the ability to
run it (mix format --check-formatted or cargo fmt --check) as part of the
CI to see if any new code is formatted, was a great added bonus.
