Generate and render a tree dynamically

[NikosAlexandris]

Is possible in some way to dynamically generate the content for a

```tree
```

code-block ?

All of the examples in https://pawamoy.github.io/markdown-exec/usage/tree/ are static ones.

I've written a small function that prints the content of a directory. Of course it can be further customised to match the expected tree code-block structure.

Example

```python exec="true"
from pathlib import Path


def print_tree(directory, level=1):
    directory = Path(directory)
    if not directory.is_dir():
        return  # Ensure it's a directory

    # Only list the first level of files and directories
    tree = str()
    for path in sorted(directory.iterdir()):
        if path.name.startswith('_'):
            continue  # Skip files or directories starting with '_'
        if path.is_dir():
            tree += f"\n    {path.name}/"  # Add slash to indicate it's a directory
        else:
            tree += f"\n    {path.name}"

    # Optionally print a trailing line after listing
    if level == 1:
        tree += '\n   '

    return tree

tree = print_tree('api/')
print(f"```\n{tree}\n```")
```

So, does it work 🙂?

Instead of using print(f"```\n{tree}\n```") I think you can simply print the tree without fences, and add result="tree" to your code block options.

Yes, it does

and your library is Awesome.

ps- And I need to fix my function to work properly :D.

Great! And thanks 😊
