📓 Access env vars in Neovim

Accessing an environment variable within Neovim from a lua script is straight forward. It is just a case of calling vim.env.env-var-name where env-var-name is the name of the environment variable e.g.

local homebrew_prefix = vim.env.HOMEBREW_PREFIX
print(homebrew_prefix)

Would print the value of the $HOMEBREW_PREFIX env var.
