    JupyterLab 2.x / 3.x Solarized Dark extension.

    The theme is originally created by Jae Hee Lee in this gist




    • JupyterLab


    • v0.2.x is mainly based on Jae Hee Lee's original theme
    • v1.x aims to provide a smoother looking.
    • Starting from v2.x, Jupyterlab v3.x support is added.


    • JupyterLab >= 2.0 or JupyterLab >= 3.0


    To install it as a prebuilt extension (requires JupyterLab >= 3.0):

    pip install jupyterlab_theme_solarized_dark

    Or install it as a source extension:

    jupyter labextension install jupyterlab-theme-solarized-dark

    Apply the theme by checking Settings -> Jupyterlab Theme -> Jupyterlab Solarized Dark

    To enable theme scrollbars, in JupyterLab, either

    • navigate to Settings -> Advanced Settings Editor -> Theme, and add "theme-scrollbars": true to User Preferences
    • OR check Settings -> Jupyterlab Theme -> Theme Scrollbars


    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_theme_solarized_dark 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_theme_solarized_dark


    jupyter labextension uninstall jupyterlab-theme-solarized-dark

    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-theme-solarized-dark within that folder.

    Packaging the extension
