Halo is a Python library for rendering animated loading indicators and task completion symbols within terminal and notebook environments. It serves as a utility for providing visual feedback in command-line interfaces to signal that background processes are active.
The library allows for the customization of loading spinner animations through the use of preset styles or custom character sequences and rotation intervals. It includes functionality to terminate active animations and replace them with specific status symbols and messages to indicate success, failure, or warnings.
The project covers a range of user interface feedback capabilities, including the display of animated loading states and the signaling of asynchronous task progress across various console-based environments.
