Arbitrary python commands for notebooks in JupyterLab
Project description
jupyterlab_commands
Support for arbitrary python commands in the command palette.
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}
