clean up div fences in jupyter generated notebooks

[trgardos]

The jupyter notebooks created by the quarto convert command and placed in jupyter_notebooks still have all the div fences which detract from the markdown cells. figure out a way to remove those.

Yes, you can use a custom filter to remove the div fences (e.g., :::) from the markdown cells when converting with Quarto. Here’s a step-by-step guide on how to achieve this:

1. Create a Custom Filter: Write a Python script that will act as a filter to remove the div fences from the markdown cells.

2. Use the Filter with Quarto: Apply this filter when running the quarto convert command.

Step 1: Create a Custom Filter

Create a Python script named remove_div_fences.py with the following content:

import sys
import json

def remove_div_fences(cell):
    if cell['cell_type'] == 'markdown':
        cell['source'] = ''.join(line for line in cell['source'] if not line.startswith(':::'))
    return cell

def main():
    notebook = json.load(sys.stdin)
    notebook['cells'] = [remove_div_fences(cell) for cell in notebook['cells']]
    json.dump(notebook, sys.stdout)

if __name__ == '__main__':
    main()

Step 2: Use the Filter with Quarto

When running the quarto convert command, you can use the --to option to specify the output format and the --filter option to apply the custom filter. Here’s how you can do it:

quarto convert ds701_book/02C-Sklearn.qmd --to ipynb --filter remove_div_fences.py

This command will convert the Quarto file to a Jupyter notebook and apply the remove_div_fences.py filter to remove all div fences from the markdown cells.

Summary

By creating a custom filter and applying it during the conversion process, you can remove all div fences from the markdown cells in your Jupyter notebooks. This approach ensures that the final output is clean and free from unnecessary markdown syntax.

Oops! not so fast. gpt4o hallucinated that command line syntax. maybe with lua filters...
