Myles Scolnick Comments - Answer Overflow

gotcha, thanks for sharing. i started this work: https://github.com/marimo-team/marimo/pull/3563 but there is a fair amount of frontend work left, and likely some parsing changes to the DAG. in the meantime, you can use raw sql with engine.execute() or maybe create a small def execute wrapper like something similar similar to the linked PR. there are also a few examples in there that might be helpful too marimo/_smoke_tests/sql/polars_sql.py marimo/_smoke_tests/sql/sql_alchemy_engine.py (only half works on main, other half depends on the PR)

Is it possible to make variables available by default in marimo notebooks? kedro + marimo

thanks for sharing @lucharo and would be awesome to have better integration with Kedro. you are probably the expert in know how they can integrated. magic commands usually just map back to python, so maybe there is an util you can import to do this, eg..

import kedro
kedro.init()

import kedro
kedro.init()

is magics the only way to integrate with kedro? could you maybe file a ticket upstream and we can chime in?

How to try a pre-release/development version locally with sandbox?

if there is a way to check if you are running from an editable install, that would help. or we could expose an environment variable

How to try a pre-release/development version locally with sandbox?

i have this code:

    marimo_deps = [d for d in dependencies if _is_marimo_dependency(d)]
    if not marimo_deps:
        # During development, you can comment this out to install an
        # editable version of marimo assuming you are in the marimo directory
        # DO NOT COMMIT THIS WHEN SUBMITTING PRs
        # return dependencies + [f"marimo -e ."]

        return dependencies + [f"marimo=={marimo_version}"]

    marimo_deps = [d for d in dependencies if _is_marimo_dependency(d)]
    if not marimo_deps:
        # During development, you can comment this out to install an
        # editable version of marimo assuming you are in the marimo directory
        # DO NOT COMMIT THIS WHEN SUBMITTING PRs
        # return dependencies + [f"marimo -e ."]

        return dependencies + [f"marimo=={marimo_version}"]

How to try a pre-release/development version locally with sandbox?

i dont think there is a great way to do this. i've commeneted out this in the code to test this. you can kinda trick the code path with MARIMO_MANAGE_SCRIPT_METADATA=true marimo edit, but that wont actually create the sandbox for you (just think you are in one).

Snowflake connection

awesome, this is a great example for me to work towards. we want to support different engines, so we definitely will support this in the med-term. how are you using snowflake out of curiosity? are you trying to explore snowflake DBs, moving/transforming data around between tables (write-heavy), or trying to show snowflake data in an app (read-heavy)?

Snowflake connection

can you share a small snippet of what it looks like using SQL alchemy with %%sql? we support SQL via duckdb (but will extend to other drivers), to learn more about the SQL support, run:

uv pip install "marimo[sql]"
mairmo tutorial sql

uv pip install "marimo[sql]"
mairmo tutorial sql

Trigger a cell inside the same notebook

yep, wrapping in a function is recommended, and would be clearer/cleaner when sharing with a co-worker. it will be more obvious what you are doing.

Potential bug in drop-down UI elements

mo.ui.dropdown, only accepts string types at the moment. 1. you can cast to a string like you do 2. you can use mo.ui.dropdown.from_series(df["col_name"] which will also do that for you. the .value you get back though will be a string. if you want the same datatypes you pass in (int, datatimes), can you file a feature request and we can support that.

Dynamic App configuration

let me know how it goes, and if you'd be willing to share your middleware that updates the html, it could be something nice to include in our docs

hmm that seems like a bug. I see it printing out to my terminal, but not the marimo output. we can look into fixing this.
