Creating a new Stack Project in a Nix Shell

There are so many different ways of building and maintaining Haskell projects.

I'm going to talk about using nix-shell and stack.

First you want a ~/.stack/config.yaml:

 local-bin-path: /home/USERNAME/.stack/bin

andrevdm

{-# LANGUAGE NoImplicitPrelude #-}
{-# LANGUAGE OverloadedStrings #-}

module Main where

import           Protolude hiding (to, (&))
import qualified System.IO as IO
import           Control.Lens ((<&>), (^.), (.~), (&), set, view)
import qualified Data.Text as Txt
import qualified Data.Conduit as C
