Warning
This extension is effectively in maintenance mode; jupyterlab-myst provides this feature (and more!) under a single extension. Feel free to check it out!
A JupyterLab extension to embed rich output in Markdown cells.
This extension implements only the machinery required to embed rich outputs. Parsing Markdown into expressions is performed with a separate plugin jupyterlab-markup-exp that must be installed:
The current value of x is {{ x }}
jupyterlab-imarkdown has to do some pretty unpleasant things in order to provide interactive Markdown.
In particular, we implement our own NotebookPanel.ContentFactory in order to inject our own IMarkdownCell.
This custom class implements routines to detect when the Markdown cell has been rendered, keep track of special eval-expr DOM nodes,
and update these DOM nodes with the result of kernel execution.
- JupyterLab >= 3.0

To install the extension, execute:
pip install jupyterlab_imarkdownTo remove the extension, execute:
pip uninstall jupyterlab_imarkdownNote: 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_imarkdown 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 buildYou 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 labWith 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=Falsepip uninstall jupyterlab_imarkdownIn 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 jupyterlab-imarkdown within that folder.
