Since this list doesn't actually make any sense, I'll list two actually great developer tools: + The Stack package manager for haskell: https://docs.haskellstack.org/en/stable/README/ https://docs.haskellstack.org/en/stable/README/ + NixOS: https://nixos.org/ https://nixos.org/ Note that NixOS' drive towards critical mass isn't complete yet. It has great Haskell support (especially since Stack has nix integration), but may not have as good support for your language. No point in switching OSes before the time is right.
