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?

Solution

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

    File.cwd!
