jupyterlab-open-url-parameter 0.3.0

JupyterLab extension to open files passed via a URL parameter

jupyterlab-open-url-parameter

JupyterLab extension to open files passed via a URL parameter.

Requirements

• JupyterLab >= 4.0

Install

To install the extension, run the following command:

pip install jupyterlab-open-url-parameter

Usage

The extension will open a file passed via a URL parameter. The URL parameter is fromURL. It is possible to pass multiple files via the fromURL parameter. The files will be opened in the order they are passed.

For example if you would like to open a notebook and a csv file:

• https://raw.githubusercontent.com/jupyterlab/jupyterlab-demo/master/notebooks/Lorenz.ipynb
• https://raw.githubusercontent.com/jupyterlab/jupyterlab-demo/master/data/iris.csv

You can append the following to the URL of your JupyterLab instance: ?fromURL=https://raw.githubusercontent.com/jupyterlab/jupyterlab-demo/master/notebooks/Lorenz.ipynb&fromURL=https://raw.githubusercontent.com/jupyterlab/jupyterlab-demo/master/data/iris.csv

Which will result in the following URL when JupyterLab is running locally:

http://localhost:8888/lab?fromURL=https://raw.githubusercontent.com/jupyterlab/jupyterlab-demo/master/data/iris.csv&fromURL=https://raw.githubusercontent.com/jupyterlab/jupyterlab-demo/master/notebooks/Lorenz.ipynb

ℹ️ This extension uses the command filebrowser:open-url available in JupyterLab by default.

Using the extension in JupyterLite

The extension can also be used in JupyterLite. Check out the documentation to learn more about adding extensions to JupyterLite.

Uninstall

To remove the extension, run the following command:

pip uninstall jupyterlab-open-url-parameter

Contributing

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_open_url_parameter 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-open-url-parameter

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-open-url-parameter within that folder.
