I'm very happy to be using Haskell professionally again after about 3 years away. I'd like to follow the Haskell style guide (https://github.com/tibbe/haskell-style-guide/blob/master/haskell-style.md) as much as possible, and I'm curious how other Emacs developers accomplish that nowadays, as well as whether and how anyone has dealt with some specific problems below.
I've looked at some of the tools like haskell-formatter, hindent, stylish-haskell, and structured-haskell-mode. I'm not opposed to using those, but I would really prefer to have a simple working emacs config that I can share with my colleagues who may or may not want to use those more "aggressive" tools.
