`alert` arg for `marimo.status.progress_bar`

[metaboulie]

Description

Add an alert arg to marimo.status.progress_bar, alert completion message when progress is completed

---

Besides,

A tiny doc issue here

in the Args part, add description for disabled

---

why this is valuable:

If I'm training a neural network and editing some other parts of the notebook, I'd like a notification when the training is done

[metaboulie]

I can implement this and fix the doc error if it's valuable

i like this idea. @metaboulie, maybe for better composition, what about an mo.toast()? then you can place the alert after spinner too or before the progress. we also also had more arguments like title/description

[metaboulie]

Do you mean something like:

for _ in mo.status.progress_bar(range(100)):
    await asyncio.sleep(0.5)
mo.toast("Finished.")

[mscolnick]

yep i think that would be great.

we already have an Alert operation we could use:

def toast(title):
   Alert(title=title).broadcast()

I think the solution should be only a few lines of code

[metaboulie]

Should we put it inside Control flow or Status?

[mscolnick]

oh status is good - maybe mo.status.toast()
