GitHub - jtpio/jupyterlab-topbar: JupyterLab Top Bar extension (original) (raw)

JupyterLab Top Bar Extensions

Monorepo to experiment with the top bar space in JupyterLab.

Similar to the status bar, the top bar can be used to place a few indicators and optimize the overall space.

Inspired by Gnome Shell Top Bar indicators.

Extensions

• jupyterlab-topbar-text: add and edit custom text
• jupyterlab-logout: add a "Log Out" button
• jupyterlab-theme-toggle: switch between the Light and Dark themes

Development

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

The jlpm command is JupyterLab's pinned version ofyarn that is installed with JupyterLab. You may useyarn or npm in lieu of jlpm below.

Clone the repo to your local environment

Change directory into the package that we want to develop

cd packages/

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

Uninstall

pip uninstall jupyterlab_topbar_text jupyterlab_logout jupyterlab_theme_toggler
