This is an nbextension that enables WYSIWYG editing functionality for HTML/Markdown cells in Jupyter.

• JupyterLab >= 3.0
• ipywidgets >= 7.0.0

This extension can be installed through PIP.

pip install jupyter-wysiwyg

OR

# Clone the jupyter-wysiwyg repository
git clone https://github.com/g2nb/jupyter-wysiwyg.git
cd jupyter-wysiwyg 

# Install the jupyter-wysiwyg JupyterLab prototype
pip install -e .
jupyter labextension develop . --overwrite

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. To develop, run each of the following commands in a separate terminal.

jlpm run watch
jupyter lab

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.

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
