[BUG] Rich not playing nice when called from Reticulate

Hi!

When called from the "Call-python-from-R" package Reticulate, Rich progress bars display incorrectly:

I've opened a bug report at Reticulate, with full description and minimum code example: rstudio/reticulate#1632

I realise this is likely some Reticulate wizardry (they remap stdout to R's console) that might be an issue, hence the bug report there, but I figured the kind developers will know much, much more about what to expect from a console, and how to get compatibility :)

Thanks a lot for any help!

I have found the root cause: Rstudio Console does not support cursor motion ANSI control sequences. I have opened a feature request upstream in rstudio/rstudio#14942 , as well as a bug report for an associated issue rstudio/rstudio#14941 .

Is there a way to make Rich progressbars working even without cursor motion control sequences, even if in a much simpler capacity?

I don't think there is much that can be don't if Reticulate doesn't support escape sequences. They clearly support the escape sequences for color, so fingers crossed they will support more...

I hope we solved your problem.

They support a subset, e.g. backspace. What they don't support is other movement :/
