How to create a progress bar that changes its text on each interation?

[sschuberth]

I struggle to create a simple progress bar that shows the progress when iterating over a list of files. I'd like to show the name of the current file, it's index relative to the total count, and the percentage. So something like

first.file 1/50 2% ➡️ second.file 2/50 4% ➡️ ...

Is this possible currently, or does the text() need to remain static?

It's not currently possible to pass in an object to modify the progress layout like that, but it's a good idea and should be added.

For now, if you aren't using any of the animated columns like progressBar() you can use a textAnimation that you update manually.

You could also clear the animation and create a new one each time the file changes, but that will cause the progress bar to reset too, so that's not ideal.

Hello, I would like to express my interest in having this feature as well.

In my particular use case, I generate intermediate results from an algorithm over a specific duration. (the duration is from the user's input)
These results are presented as a matching percentage also based on the user’s input. Unfortunately, with the current progress bar, I am unable to display the fluctuating match percentage over time. (Or maybe there is a way that I did not see)

Anyway, I would like to thank you for the work that has been accomplished thus far. It is greatly appreciated. :-)

@CharlyRien I'm working on this right now on the multi-progress branch. If you're able to build and test it out, I'd love any feedback you have. I gave an example of the new API in #149 (comment), or you can look at the sample.

Hey @ajalt I'll probably test this out this week.
