Class Method Details

.beta_code_to_greek(beta_code, custom_map: {}) ⇒ Object

This method is absurd. But having the logic all in one method makes it easier to work with than having it spread across multiple methods. It also makes it easier to compare the logic to the Beta Code libraries in other languages. rubocop:disable Metrics/MethodLength rubocop:disable Metrics/AbcSize
