Symbol’s value as variable is void: hie-nix//default-nix-wrapper

[commandodev]

I'm getting a problem when I'm trying to run , s b (to load the repl):

hie-nix command: nix-shell -I . --command hie-wrapper --lsp -d -l /tmp/hie.log /home/ben/<...>/shell.nix [2 times]
Loading /home/ben/.emacs.d/.cache/company-statistics-cache.el (source)...done

hie-nix//haskell-nix-wrapper: Symbol’s value as variable is void: hie-nix//default-nix-wrapper

I also noticed a problem with the init-lsp-haskell function. It should be:

(defun hie-nix/init-lsp-haskell ()
  (use-package lsp-haskell
    :init (add-hook 'haskell-mode-hook #'lsp)))

I'll send a PR for that one separately
