## 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

```python

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}

```

```python3

c.JupyterLabCommands.commands = {'command display name': python_function, ...}

```
