jupyter-cgi-theme 0.2.0

The JupyterLab CGI theme

jupyter_cgi_theme

The JupyterLab CGI theme. The extension for JupyterLab, published as a PIP package, adds two CGI-branded themes (light and dark) and some UI elements.

This project was initialized using a copier template for Jupyterlab extension: https://github.com/jupyterlab/extension-template

Development Requirements

To initialize a working development environment, ensure you have the following installed on your machine:

• Node
• npm
• Yarn
• pip
• Python
• JupyterLab

The local development environment uses the following versions:

• Node: 20.12.2
• npm: 10.5.0
• pip: 24.2
• Python: 3.11.3
• JupyterLab: 4.2.4

The template used to create this extension suggests using:

• JupyterLab >= 4.0.0

Install the published package (production use)

⚠️ Note: Your extensions may break with new releases of JupyterLab. As noted in Backwards Compatibility, Versions and Breaking Changes, JupyterLab development and release cycles follow semantic versioning, so we recommend planning your development process to account for possible future breaking changes that may disrupt users of your extensions. Consider documenting your maintenance plans to users in your project, or setting an upper bound on the version of JupyterLab your extension is compatible with in your project’s package metadata.

To install the extension, execute:

pip install jupyter_cgi_theme

Uninstall

To remove the extension, execute:

pip uninstall jupyter_cgi_theme

Development

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 instead of jlpm below.

# Clone the repo to your local environment
# Change directory to the jupyter_cgi_theme directory

# Install package in development mode
pip install -e "."

# Install js packages
jlpm install

# 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 simultaneously 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 jupyter_cgi_theme

In development mode, you will also need to remove the symlink created by the 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 jupyter-cgi-theme within that folder.
