Proglog callback documentation needed

[tburrows13]

The main new feature in version 1.0 is the ability to customise the progress bars using the library Proglog. This is almost entirely undocumented apart from a section in the README. The relevant commit is https://github.com/Zulko/moviepy/commit/bfad5eabfaa32fc11b5056736b7b0f4bb7ccf878.

Hey! The proper documentation for this would be to refer to simply refer to the proglog Github page:

How would I make a text based progress bar?

Can you describe the effect you are looking for?

[512DuncanL]

Something that looks like Progress: |################## | (90%)

[512DuncanL]

it should stay after the process ends

Ok. Proglog is not really a way to make custom progress bars, it is a system to redirect the progress data to the framework of your choice (either a python progress bar logger like tqdm, or a tkinter or web-ui logger).

So what you are trying to achieve is doable but the steps would be:

• Find a progress bar framework you like, and that looks like the progress bar you showed above.
• Write a MyCustomBarLogger class (on the model of TqdmBarLogger) that works with that framework you like.
• Provide a MyCustomBarLogger instance as the logger in MoviePy.
