How to stop execution in an embed notebook

[mb-915]

Hello, I'm using the new embed function and I want to stop execution book in the embeded notebook.

Here is as an example of what I want to do :

analyze.py

import marimo

__generated_with = "0.9.3"
app = marimo.App()

@app.cell
def __():
    import marimo as mo

    from select_fruit import app as select_fruit
    return mo, select_fruit


@app.cell
async def __(select_fruit):
    fruit = await select_fruit.embed()
    fruit.output
    return (fruit,)


@app.cell
def __(fruit):
    selected_fruit = fruit.defs["fruit"].value
    assert selected_fruit is not None, "This should not be possible"
    f"selected fruit is {selected_fruit}"
    return (selected_fruit,)


if __name__ == "__main__":
    app.run()

select_fruit.py

import marimo

__generated_with = "0.9.3"
app = marimo.App()


@app.cell
def __():
    import marimo as mo
    return (mo,)


@app.cell
def __(mo):
    fruit = mo.ui.dropdown(["apple", "banana", "carrot"])
    fruit
    return (fruit,)


@app.cell
def __(fruit, mo):
    mo.stop(fruit.value is None, mo.callout("Select a fruit"))
    return


if __name__ == "__main__":
    app.run()

(on gist : https://gist.github.com/mb-915/a9e510693bbbc49c279e1f09570cd118)

analyze.py embeds select_fruit.py, and I want to stop the execution of analyze.py with a stop directive in select_fruit.py.
This example does not work : when you run the select_fruit.py alone, the mo.stop works as expected, but when you run analyze.py, the stop message is shown but the execution continues and I do not know how to make my celle dependant on the stop of the embeded notebook (if it is possible)

Due to the await, I'm not sure if it is possible.

@mb-915 - do mo.stop() not work for you?

Sorry, I just noticed that I pasted two time the same file.

I updated my first message :

I used mo.stop in select_fruit.py but it doesn't work : when you run the select_fruit.py alone, the mo.stop works as expected, but when you run analyze.py, the stop message is shown but the execution continues and I do not know how to make my celle dependant on the stop of the embeded notebook (if it is possible)

It might be that mo.stop does not work across embedded notebooks. If this is still an issue, could you file an issue.
