By coincidence there are a couple of other Erlang autoformatters under development at the moment:<p>- rebar3_fmt: <a href="https://github.com/AdRoll/rebar3_format" rel="nofollow">https://github.com/AdRoll/rebar3_format</a> - offers lots of config options, as opposed to steamroller which has very few.<p>- erlfmt: don't think this has been released yet. It's designed to (probably) only change whitespace, as opposed to steamroller which makes minor code improvements.<p>An exciting time for Erlang developer tools!
