How To Get The Root Directory Of an Elixir Project

In an Elixir project, you can use 

Path.expand

to define a file or directory as a relative path from the current file.

For example: Path.expand("../../../lib/file.ex")

but how about finding a path from the root level of the project?

In case of an umbrella app, you can create a key in your config.exs file :

config :some_app,
  project_root: File.cwd!

And then use that value from wherever you want in your project :

project_root = Application.fetch_env!(:some_app, :project_root)

If you'd like to get the project's root directory, use

File.cwd!
