[REQUEST] All or nothing progress bar showing indeterminate state with elapsed time

[peterjc]

I have a mixture of tasks which I want to display, most of which I can update the progress for, and am showing the elapsed time and NofM:

PROGRESS_BAR_COLUMNS = [
    TextColumn("[progress.description]{task.description}"),
    BarColumn(),
    TaskProgressColumn(),
    # Removing TimeRemainingColumn() from defaults, replacing with:
    TimeElapsedColumn(),
    # Add this last as have some out of N and some out of N^2:
    MofNCompleteColumn(),
]

This gives me something like this, starting with an empty (grey) bar, then a red partly filled bar, and finally a full green bar:

Indexing ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━   0% 0:00:00  0/10
Indexing ━━━━━━╺━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━  20% 0:00:18  2/10
Indexing ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━╺━━━  90% 0:00:58  9/10
Indexing ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 100% 0:01:00 10/10

That is all good so far.

However, some tasks have a known number of steps (say 10), but I cannot monitor their progress, so what to show the indeterminate animated state AND the elapsed time, and then when finished show the standard green 100% bar:

I can get the indeterminate state using start=False, but then the elapsed time does not show:

In ASCII art:

Indexing ━━━━━<<━━>>━━━━━━━<<━>>━━━━━━━━<<━>>━━━━   0% -:--:--  0/10

I can get the indeterminate state using total=None, but I do have a value, and would like the % place holder.

In ASCII art total=None gave:

Indexing ━━━━━<<━━>>━━━━━━━<<━>>━━━━━━━━<<━>>━━━━  0:00:10  0/?

I'd like something like that visually but with the time, and perhaps ?/total at the end:

Indexing ━━━━━<<━━>>━━━━━━━<<━>>━━━━━━━━<<━>>━━━━   0% 0:01:23  ?/10

Is this currently not possible? Thank you!

Tested with rich 13.9.4 on Python 3.12 on macOS.

Perhaps TaskProgressColumn should show ?% for indeterminate?

Indexing ━━━━━<<━━>>━━━━━━━<<━>>━━━━━━━━<<━>>━━━━   ?% 0:01:23  ?/10
