MathJax 3 math renderer for JupyterLab

jupyterlab-mathjax3-web

A JupyterLab extension for rendering math with MathJax 3.

The default LaTeX renderer in JupyterLab uses MathJax 2. This extension substitutes the MathJax 2 renderer with the MathJax 3 renderer.

Compared to the official jupyterlab-mathjax3 which introduces the MathJax 3 into JupyterLab via node and webpack, this extension introduces MathJax 3 to the browser's global environment by loading script from the web, so that MathJax 3 can be used by other entities in JupyterLab like our jsxgraph-magic.

Requirements

• JupyterLab >= 3.0

Install

pip install jupyterlab-mathjax3-web

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 jupyterlab-mathjax3-web directory
# 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 run 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 run 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 run 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 jupyterlab-mathjax3-web

Then you need to manually remove the labextension because it seems that the above won't remove these JupyterLab files:

cd PYTHON_ENV/share/jupyter/labextensions
rm jupyterlab-mathjax3-web -rf

where PYTHON_ENV should be expanded to your Python environment.

Note

This JupyterLab extension will disable the official MathJax 2 and MathJax 3 extension to avoid potential conflict.
