Package: music21 Environment File Configuration (src.m21_environment)

Module: m21_environment.main.py

This module contains the implementation of various functions for managing user preferences for the Music21 library, including setting user preferences, checking the environment file, and displaying the environment file.

The set_user_preferences function is used to prompt the user for various settings and set these as preferences in the Music21 environment. The function handles the creation of a new environment file if it does not already exist.

The check_environmentFile function is used to verify if the Music21 environment file exists. If it does not exist, the function prompts the user to either create a new one or continue without creating one.

The display_environment_file function is used to display the contents of the Music21 environment file to the user. If the environment file does not exist, the function informs the user and provides instructions on how to create a new one.

Each function in this module is designed to handle any exceptions that occur during its execution and display these to the user.

Functions

• set_user_preferences: Prompts the user for various settings and updates these preferences in the Music21 environment. Also takes care of creating a new environment file if it doesn’t exist.

• check_environmentFile: Verifies the presence of the Music21 environment file. If not found, it asks the user to either create a new one or continue without one.

• display_environment_file: Showcases the contents of the Music21 environment file. If the file doesn’t exist, the function notifies the user and provides steps to create a new one.

iMaT.src.m21_environment.main.display_environment_file()

Display the contents of the music21 environment file.

This function reads the music21 environment file and displays its key-value pairs to the user. If the environment file does not exist, it informs the user and provides instructions on how to create a new one. The function is useful for users to check and understand their current music21 settings.
