defmodule Recase.PathCase do
  @moduledoc """
  Module to convert strings to `path/case`.

  This module should not be used directly.

  Path case preserves the original case,
  but inserts path separator to appropriate places.

  By default uses `/` as a path separator.

  ## Examples

      iex> Recase.to_path "foo_barBaz-λambdaΛambda-привет-Мир"
      "foo/bar/Baz/λambda/Λambda/привет/Мир"
