jupyterlab_courselevels

JupyterLab extension to

• display cells in colors based on their intended audience level; the color codes follows the logic of ski tracks

  • green : basic - all students should know that
  • blue : intermediate - if you want to dig a little more
  • red : advanced - for the geeks

• in addition some cells may show up with a surrounding frame, to emphasize the course structure

• the extension also comes with convenience tools to manage admonitions

Important limitation

because of the way MyST markdown is rendered, colors and frames are correctly rendered within Jupyter Lab, but they will not render properly on code cells in the jupyter-book output

For this reason, colors and frames are no longer relevant on markdown cells, and we use admonition instead

Requirements

• JupyterLab >= 4.0.0

Install

To install the extension, execute:

pip install jupyterlab_courselevels

Uninstall

To remove the extension, execute:

pip uninstall jupyterlab_courselevels

misc commands

as well as for adding/removing an admonition around a cell

persistence

this is done by adding the following tags in each cell

• level_basic
• level_intermediate
• level_advanced
• framed_cell

rendering

we rely on the jupyterlab-celltagsclasses extension, which will set classes like e.g. cell-tag-level_basic

settings

by default, no button is displayed; you can set the show_level_buttons boolean setting to true to get the buttons to display in the toolbar

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 in lieu of jlpm below.

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

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 jupyterlab-courselevels within that folder.
