jupyterlab_scheduler v0.1.6

jupyterlab_scheduler

A simple plugin for scheduling files for recurring execution using the cron utility within the Jupyter Lab UI. Use cases

Security Note: Cron jobs are executed under the permission set of the JupyerLab process; if you start jupyter as root (not recommended!) every job that is scheduled via the UI will also run as root.

Prerequisites

• JupyterLab
• Cron installed on the JupyterLab host

Installation

To install using pip:

pip install jupyterlab_scheduler

jupyter labextension install jupyterlab_scheduler

Development

For a development install (requires npm version 4 or later), do the following in the repository directory:

# Clone the repo to your local environment
# Move to jupyterlab_scheduler directory
# Install dependencies
npm install
npm run build:lib
# Install your development version of the extension
jupyter labextension install .

You run JupyterLab in watch mode to watch for changes in the extension's source and automatically rebuild.

# Run jupyterlab in watch mode
jupyter lab --watch

Now every change will be built locally and bundled into JupyterLab. Be sure to refresh your browser page after saving file changes to reload the extension (note: you'll need to wait for webpack to finish, which can take 10s+ at times).

# Run jupyterlab in auto reload mode
jupyter lab  --autoreload --NotebookApp.token='' --NotebookApp.password='' --no-browser

Works better when developing server extensions

Publishing

To build the plugin for disitibution on Pypi:

python3 setup.py sdist bdist_wheel

python3 -m twine upload --repository pypi dist/*

Uninstall

jupyter labextension uninstall jupyterlab_scheduler
