For Python (ipykernel) in Jupyter, we have the magic command %run ./some_notebook.ipynb to run another notebook (e.g. effectively "importing" functions from another notebook).

Can you do the same thing with javascript running Deno kernel in Jupyter?

%run doesn't seem to work with Deno kernel.

There is a Deno.run method, but I can't figure out if this is the purpose of the method or what the syntax would be (via Google, trying to track it down in Deno codebase, etc).

For example, Deno.run('./some_notebook.ipynb') yields

Stack trace:
TypeError: Cannot read properties of undefined (reading '0')
    at Object.run (ext:deno_process/40_process.js:143:10)
    at <anonymous>:3:6

Does anyone know if this is possible? Thanks

(Sorry, I'm actually using jupyterlab, but I just tested and it's the same way in jupyter notebook)

====================

Edit to add a couple more things tried:

I realized I could just parse and eval the contents of the notebook (could be a big security risk, but I'm just using this as a tool for my early and local development), and this does evaluate the commands from the notebook, but the functions/variables aren't available in other cells (maybe intentional based on security threat). I couldn't find anything like a Deno.eval to get around this.

let notebookContent = await Deno.readTextFile('./TestImportDenoNotebook.ipynb')
let notebookJSON = JSON.parse(notebookContent);
for (const cell of notebookJSON.cells) {
    const cellSource = cell.source.join('\n');
    new Function(cellSource)();
}

Also, I found the syntax for Command (run in Jupyter), and it seems to run the notebook, but probably in a separate process (I still don't have access to the functions/variables from the other notebook):

let filename = './TestImportDenoNotebook.ipynb';
const command = new Deno.Command("jupyter", {
      args: ["execute", "--kernel_name=deno", filename],
});
const { code, stderr } = await command.output();
