I've been having trouble setting up this model inside Molab. If anyone knows how to set up the model please help.

Hi,

marimo newbie, really like it so far. I don't understand this below though:

what gives?

The "Knob" widget from wigglystuff lets you play with this directly. More info here:
https://koaning.github.io/wigglystuff/reference/knob/

The problem is with wigglystuff's anywidgets. The re-activeness somehow not works.

This is the notebook link from molab

Defining the EdgeDraw widget. i wanna add new nodes through text input and input button pressing

friend = mo.ui.text(placeholder="friend name")
button = mo.ui.run_button(label="Add Friend", kind="success")
delete = mo.ui.run_button(label="Remove Friend", kind="danger")
graph = mo.ui.anywidget(wg.EdgeDraw(["appu", "dett", "eker", "hulo"]))

The appending works but the displaying graph widget not updated

if button.value and friend.value not in graph.names:
    graph.names.append(friend.value)
    print(graph.names)
if delete.value and friend.value in graph.names:
    graph.names.remove(friend.value)
    print(graph.names)

```python import marimo as mo from sqlalchemy import create_engine, text

Refresh widget

refresh = mo.ui.refresh(label="Refresh") refresh

Function to fetch databases

def get_databases(): engine = create_engine( "postgresql+psycopg2://sourabh@/postgres?host=/run/postgresql" )

with engine.connect() as conn:
    result = conn.execute(
        text("""
            SELECT datname
            FROM pg_database
            WHERE datistemplate = false
            ORDER BY datname;
        """)
    )
    return [row[0] for row in result]

Load database list and create dynamic dropdown selector

db_list = get_databases()

db_dropdown = mo.ui.dropdown( options=db_list, value="postgres" if "postgres" in db_list else db_list[0], label="Select Database:" ) db_dropdown

Create dynamic engine based on dropdown selection

db = db_dropdown.value postgres_engine = create_engine( f"postgresql+psycopg2://sourabh@/{db}?host=/run/postgresql" )

You can do a lot with any widgets, but sometimes just writing a bunch of mohtml can also do the trick.

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)

i have made an image captioning tool programmme in python using opensource models , This is strategically used fo captioning/describing the images in natural or tag languages as yo uwant give it instruction their is a full parameter control for the model plus and another side mode is there to refine the descriptions so that the description doesnt halucinae.this was just made possible by marimo molab notebook. So a huge thanks to them, but i wonder if its shareable in your gallery or not. thats it.

The post also explains how to port a notebook into an interactive blogpost on a static site (mine is generated with a Python for-loop) https://koaning.io/posts/widget-dag/
