fails-components-jupyter-interceptor 0.0.2

A collections of plugins intercepting kernel messages and other message, to steer outputs remotely

fails_components_jupyter_interceptor

This is an extension, that intercepts message's to and from output views and its widgets, in order to puppet external jupyter deployments of clients listening to a central instructor. It can be used together with the fails_components_jupyter_launcher. Currently, only widgets based on ipywidgets are supported.

Requirements

• JupyterLab >= 4.0.0

Install

To install the extension, execute:

pip install fails_components_jupyter_interceptor

Uninstall

To remove the extension, execute:

pip uninstall fails_components_jupyter_interceptor

Contributing

Development install

Note: You will need NodeJS to build the extension package.

The jlpm command is JupyterLab's pinned version of yarn that is installed with JupyterLab. You may use yarn or npm in lieu of jlpm below.

# Clone the repo to your local environment
# Change directory to the fails_components_jupyter_interceptor directory
jlpm build
# Install package in development mode
pip install -e "."
# Link your development version of the extension with JupyterLab
jupyter labextension develop . --overwrite
# Rebuild extension Typescript source after making changes
jlpm build

You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.

# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm watch
# Run JupyterLab in another terminal
jupyter lab

With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).

By default, the jlpm build command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:

jupyter lab build --minimize=False

Development uninstall

pip uninstall fails_components_jupyter_interceptor

In development mode, you will also need to remove the symlink created by jupyter labextension develop command. To find its location, you can run jupyter labextension list to figure out where the labextensions folder is located. Then you can remove the symlink named @fails-components/jupyter-applet-view within that folder.

Testing the extension

Frontend tests

This extension is using Jest for JavaScript code testing.
