Support Marimo notebook in Google Colab

[scls19fr]

Marimo is an open-source reactive notebook for Python — reproducible, git-friendly, executable as a script, and shareable as an app. https://marimo.io/

Supporting it inside Google Colab could be a nice improvement.

Marimo can works behind JupyterHub See https://github.com/marimo-team/marimo/issues/905

Is there a specific feature you're looking for here? What does Marimo do that Colab does not do as well?

Google Colab has some limitations compared to reactive notebooks like IPyFlow, Marimo, and Pluto.jl. Here are key reasons why reactive notebooks are often considered superior:

• Out-of-order execution: Colab allows cells to be executed in any order, potentially leading to hidden state and inconsistent results. Reactive notebooks automatically handle dependencies between cells, ensuring consistent and reproducible outputs.

• Real-time updates: In reactive notebooks, when you change a cell, all dependent cells update automatically. This keeps your entire notebook consistent and saves time on manual re-execution, which is necessary in Colab.

• Reduced hidden state: Colab notebooks can accumulate hidden state as cells are executed multiple times or in different orders. Reactive notebooks minimize this issue by clearly showing dependencies and updating affected cells.

• Better reproducibility: The reactive model makes it easier to create reproducible analyses since the notebook's state is always consistent with the visible code. In Colab, reproducing results can be more challenging if cells are run out of order.

• Improved collaboration: While Colab offers good collaboration features, reactive notebooks can make it even easier for multiple people to work simultaneously, as changes propagate automatically.

• Enhanced debugging: It's often easier to track down errors in reactive notebooks because you can see exactly which cells are affected by a change. In Colab, errors might be less obvious if they result from out-of-order execution.

• More intuitive workflow: Reactive notebooks often feel more natural to use, as they behave more like a spreadsheet or a reactive programming environment.

Amazing list, thanks. We're working on a few of these right now. More to come.
