An example project setup for Haskell using VSCode. Fire those commands hoping for the best.

Install Stack

Install stack

wget -qO- https://get.haskellstack.org/ | sh

Install HIE

With Nix

Install cachix client

nix-env -iA cachix -f https://cachix.org/api/v1/install

Install some HIE for lts-14.21(ghc-8.6.5)

nix-env -iA selection --arg selector 'p: { inherit (p) ghc865; }' -f https://github.com/infinisil/all-hies/tarball/master
