jupyterlab-snippets

Snippets Extension for JupyterLab.

This extension is composed of a Python package named jupyterlab-snippets for the server extension and a NPM package named jupyterlab-snippets for the frontend extension.

Requirements

• JupyterLab >= 2.0
• Node.js

Install

pip install jupyterlab-snippets
jupyter lab build

Usage

Add snippets in [jupyter_data_dir]/snippets (see: https://jupyter.readthedocs.io/en/latest/projects/jupyter-directories.html#id2)

To find the Jupyter data directory, run:

$ jupyter --path

This will for example show the following list on macOS:

config:
    /Users/<username>/.jupyter
    ...
data:
    /Users/<username>/Library/Jupyter
    /Users/<username>/miniconda3/envs/<envname>/share/jupyter
    ...
runtime:
    ...

Use the first directory listed under data: to add files to, these become snippets in the menu. Each file contains one snippet. Directories can be used to organize the snippet files and will become submenu's in the menu.

In JupyterLab, use the "Snippets" menu to select the snippet:

Convert snippets from jupyter-boilerplate format

See jupyter-boilerplate-converter on how to convert snippets from the jupyter-boilerplate classic notebook extension (not available for JupyterLab) to jupyterlab-snippets.

Troubleshoot

If you are seeing the frontend extension but it is not working, check that the server extension is enabled:

jupyter serverextension list

If the server extension is installed and enabled but you are not seeing the frontend, check the frontend extension is installed and enabled:

jupyter labextension list

If it is installed, try:

jupyter lab clean
jupyter lab build
