JSONiq JupyterLab Extension

jsoniq-jupyterlab-extension is a JupyterLab extension that adds basic token highlighting for JSONiq code. Syntax highlighting with CodeMirror is enabled for jsoniq cells using the %%jsoniq magic and for .jq files.

Features

• Basic token highlighting - provides JSONiq token highlighting for %%jsoniq magic cells within Python notebooks.
• Syntax highlighting for .jq files - can be enabled for .jq files using the Jupyter language selector.

Installation

Install the extension from Python packaging. No npm or yarn installation is required for users.

To install, run:

pip install jsoniq-jupyterlab-extension

After installing the package, you may need to enable the extension in JupyterLab:

jupyter labextension enable jsoniq-jupyterlab-extension

Usage

Once the extension is installed and enabled, it automatically recognizes jsoniq magic cells and files for syntax highlighting.

Example

%%jsoniq
for $book in json-file("books.json")
where $book.price lt 20
return $book.title

This cell should become highlighted.
