About

This code lets you inject arbitrary commands into the JLab frontend. There are a variety of reasons why one might want to execute python commands outside of a notebook and a console:

  • a predefined NBConvert function that you dont want included in the converted result
  • interacting with VCS without including that interaction in the notebook
  • etc...

Installation

pip install jupyterlab_commands
jupyter labextension install jupyterlab_commands
jupyter serverextension enable --py jupyterlab_commands

Example

jupyter_lab_config.py

def convertMe(request, *args, **kwargs):
    import subprocess, tornado, os, os.path, json
    data = json.loads(tornado.escape.json_decode(request.body))
    path = os.path.join(os.getcwd(), data['path'])
    subprocess.run(["jupyter", "nbconvert", path, '--to', 'html'])
    return {'body': 'ok'}

c.JupyterLabCommands.commands = {'sample_command': convertMe}
