Jupyter extension that provides an interactive tour and adds MAAP specific information to the help tab

Requirements

• JupyterLab >= 3.4.4

Install

To install the extension, execute:

pip install maap_help_jupyter_extension

Uninstall

To remove the extension, execute:

pip uninstall maap_help_jupyter_extension

Contributing

Development install

Note: You will need NodeJS v14 to build the extension package.

# 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

If you would like to disable the default jupyter lab tutorial, (MAAP specific one will still be enabled), run

jupyter labextension disable "jupyterlab-tour:default-tours"

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.

The first command installs the dependencies that are specified in the setup.py file and in package.json. Among the dependencies are also all the JupyterLab components that you want to use in your project.

It then runs the build script. In that step, the TypeScript code gets converted to javascript using the compiler tsc and stored in a lib directory. And a condensed form of the Javascript is copied in the Python package (in the folder maap_help_jupyter_extension/labextension). This is the code that would be installed by the user in JupyterLab.

The second command creates a symbolic link to the folder maap_help_jupyter_extension/labextension so that extension is installed in development mode in JupyterLab.

The third command allows you to update the Javascript code each time you modify your extension code.

Now, we can run the extension. Note by adding --watch, we just have to refresh the browser when the project is rebuilt.

jupyter lab --watch

Development uninstall

pip uninstall maap_help_jupyter_extension

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 maap-help-jupyter-extension within that folder.
