ui element value

Plain Text
@app.cell
def input_cell(mo):
    my_input = mo.ui.text()
    my_input
    return (my_input,)


@app.cell
def result_cell(my_input):
    my_input.value
    return


If I run input_cell, the result_cell will immediately be run after that (because my_input.value). I know that we can change the default value or use callback functions, but it could be a good idea to prevent dependent cells do not run and wait for the users actual input.

Execution Order

I thought asking this here before opening an issue on github.

Consider this notebook with these cells.
(it is a versy small simplified version of hg agents course)

I have attached the screenshot of dependencis,

  1. Cell-1 should be run before cell-2. but as in this there are no explicit dependency between them and the cell-2 is getting the env variables underhood we can not guarantee this execution order.
easy solution to solve this problem is mergin cell-1 and cell-2, but for the next problem we can not do that.

  1. Cell-2 should run before cell-5 and cell-4
to be able to monitor the agent. Again this order is not guaranteed.
One dirty solution would be to define a variable in Cell-2 and reference it in Cell-5 and Cell-4.

Does Marimo provides a proper solution for this promblem?
