Add progress bars for long-running item- or album-level operations #5711
Description
Proposed solution
There are a few Python progress bar libraries for terminal applications, including the popular TQDM as well as Enlighten. TQDM is great, of course, but it has the nasty habit of interacting poorly with log lines or other messages sent to STDOUT. Enlighten handles the terminal output the way one would like it to be done - the progress bar at the bottom, and all the log messages above it with no interaction between the two.
Objective
See related discussion
Goals
- Add a progress bar to the bottom of the terminal for most long-running operations, particularly imports and built-in plugins.
- Provide
beets.ui.*helper functions to make it easy for plugin developers to adopt the same progress bar, and to provide a central place for modifying behavior in the future. - Reach out to plugin authors to invite them to adopt the progress bar in their plugins.
Non-goals
- Reinventing any wheels - we just want to use an off-the-shelf progress bar library, not to develop a new one ourselves.
- World peace
- Free trade
- Enlightenment
Anti-goals
- Global thermonuclear war
