when I run ghci in nix-shell I can see all the IHP.Prelude code but I can't see any of the code in my current application. How do I interact with my own code in ghci? Trying things in a repl is one of the main reasons why I like Haskell, but so far I haven't been able to do it with my own code. I assume it's some nix file setting, but I can't find any straight forward information on how to do this. I usually work with stack, so I am a bit lost in IHP with nix.
