Using Nix for project dependencies/asdf replacement

A while back I started to use nixos as a system to configure my dev environment across both MacOS and linux. This allows me to have one script to rule them all.

As a byproduct, a combination of nix and direnv can be used to manage project dependencies and replace asdf allowing me to remove it.

# .envrc
use nix

# shell.nix
{pkgs ? import <nixpkgs> {}}:
with pkgs; # Defines a shell.

  mkShell {
	# project dependencies
	buildInputs = [
	  git
	  direnv
	  go
	  hugo
	];
  }

The combination of these files will guarantee that go and hugo are available in the project directory, emulating asdf’s functionality.
