Agreed, but lots of people (especially newbies) are on windows, and it helps to have one tool work everywhere, and in exactly the same way.

yeah, therefore Nix

Gah.. we.. just.. discussed.. how nix doesn't work on Windows 7. Anyways, no reason to argue, can you point me to the most newbie friendly nix setup (linux/mac) for Haskell development? I'll try it out myself and with some people new to Haskell, and report back on how that goes.

my instructions for my classes: 1. Clone data61/fp-course 2. Run 'nix-shell' from there 3. Run 'ghci' Now you're writing #Haskell!!

cycle detected in the references of ‘/nix/store/8bjxnl81lqqn2x6da6dzak8dm4plyh2a-jailbreak-cabal-1.3.2 .. error: build of ‘/nix/store/z767pb4wiqx3wxkmprg902x7jipshj4s-ghc-8.0.2-with-packages.drv’ failed /nix/var/nix/profiles/default/bin/nix-shell: failed to build all dependencies

you're on an old version of nixpkgs. At this point I do the same as @dibblego and tell people to just use 'nix-shell -p ghc'

Okay, so how do I switch to a new version of nixpkgs? What are the steps for setting up a full nix based project? Also, just saying, this is something I would never face with stack. I can build any old or new project without changing anything in any other part of my system.
