[BUG] bar_format parameter doesn't seem to be working

[julienbosse]

Describe the bug

Hi, first of all, thanks for this, it's great ! I'd like to report what I think is a bug. I'm trying to get to display only the progress bar and no additional info. Like this :

Unfortunately, with stqdm, even when setting the bar_format parameter, additional info still shows.

To Reproduce

Steps to reproduce the behavior :

from stqdm import stqdm
from time import sleep

for item in stqdm(range(10), bar_format="{bar}"):
    sleep(0.5)

I might be missing something, but since stqdm inherits from tdqm, I think this should be working ?

Hi @julienbosse !

Thanks for reaching out.
This is a funny one.

I am going to have to think about it a bit more to have a good solution to this.
What is your objective? Get rid of the text part?

What's happening.
stqdm does not rely on the bar part of tqdm but use st.progress for this part (it looks nicer, and I think it was faster when I first created it).
To do this properly I rely on tqdm.format_meter which do all the formatting logic.
I use ncols=0 which is supposed to shrink the progress bar to 0 and write the result of format meter to st.write.

stqdm/stqdm/stqdm.py

Lines 88 to 89 in b1bdf74

	self.st_text.write(self.format_meter(n, total, **{**kwargs, "ncols": 0}))
	self.st_progress_bar.progress(n / total)

It appears that there is a shortcut for the ncols case which ignores bar_format and just return a standard format.
https://github.com/tqdm/tqdm/blob/4c956c20b83be4312460fc0c4812eeb3fef5e7df/tqdm/std.py#L620-L621

So I should probably change that, on the other hand, your formatting will return a double bar, which I guess is not what you are looking for.

To do this properly I rely on tqdm.format_meter which do all the formatting logic.

tqdm.format_meter itself relies on bar_format so it's strange that it does not work out of the box
