logger_utils

Utilities to create and set the logger.

Manim’s logger can be accessed as manim.logger, or as logging.getLogger("manim"), once the library has been imported. Manim also exports a second object, console, which should be used to print on screen messages that need not be logged.

Both logger and console use the rich library to produce rich text format.

Classes
