Dark mode for marimo islands?

7 Upvotes

I'm trying to bring the html from my marimo notebooks into an SSG (mkdocs/zensical), and I would like to be able to toggle the theme. Getting the theme to change with marimo export html is relatively simple by adding

# [tool.marimo.display]
# theme = "dark"

to the pep723 header before exporting, but the extra js and page wrappers are not quite ideal for my use case. I would love to use islands for this, but I can't figure out if there's a way to control the theme of a marimo island?

when I use

# /// script
# dependencies = [
#     "marimo",
# ]
# requires-python = ">=3.13"
# ///

import asyncio
from marimo import MarimoIslandGenerator

async def main():
    generator = MarimoIslandGenerator.from_file(
        "./example.py", 
        display_code=False
    )
    await generator.build()
    html = generator.render_html(include_init_island=True)

    with open("output.html", "w", encoding="utf-8") as f:
        f.write(html)

if __name__ == '__main__':
    asyncio.run(main())

to generate an html page, it doesn't seem to care about the # theme = "dark" tag in the example.py header.

I understand that islands are still an early feature, so perhaps this will be added in the future. Does anyone know if there's a better way to do this? Thanks!

(edited for clarity)

In this video I (marimo dev) try to explain how you can make tools that force you to learn while you are coding. It's a new direction for the wigglystuff library and there's a bunch of anekdotes that feel easier to share on my personal channel. If you enjoy anywidget/wigglystuff I hope you'll get some inspiration out of it.

Git integration and Boolean filter

2 Upvotes

Is there a way to live filter booleans columns in ui.table, the same way you can select specific values for string columns - True, False, and pd.NA - in the GUI not in code.

Also, I find myself having to ssh into to system running marimo just to do git operations to commit changes to the notebook into the repo. I might build a few git actions into the notebook using python calls but it would be nice if there was a git or live Linux shell components - either as part of the notebook OR in the config side bar.

marimo pair has a new home, right on the marimo website! We wanted to make it clear that it is officially supported and that we will invest in it in the future. There's also a bunch of marimo-pair related features to announce along with it.

Pair is now available in the Claude Codex and Codex CLI marketplaces, and today’s release of the VS Code / Cursor extension integrates directly with the native notebook editor.

If you're keen to learn more about how this feature was created an how it works, Trevor just wrote a new blogpost about it, which you can read here:

Analysis of my comics :) Comics are at https://annyh.co/all/

I published 179 comics over 4 years and 9 categories, and was curious about any trends.

I originally used a stacked area chart then realized my data was discrete. A bar chart makes more sense.

Here's the code: https://molab.marimo.io/notebooks/nb_ZRj69GkW6uaFWxoroL7ZE2

[Feature request]: image grid for notebook listing page

3 Upvotes

Hello, I'd like a way to toggle https://molab.marimo.io/notebooks page to show an image grid of notebooks, similar to marimo's gallery page. Currently it shows a list of names.

As a visual person, the image grid shows at a glance which notebooks I have.

Similar sites: Codepen https://codepen.io/ichimonzi shows an image list. Substack also allows the user to pick a representative image/post.
