Jupyter Notebook Quick Look

The Quick Look plugin adds native preview support for Jupyter notebook files in macOS Finder. When a user selects a notebook and triggers Quick Look, the plugin renders the notebook’s contents—code cells, markdown, and output—directly in the preview pane, allowing a fast visual inspection without opening the file in an editor or Jupyter server.

It is targeted at macOS users who work with Jupyter notebooks and want a convenient way to browse them from the file system. The plugin requires Python 3 with the Jupyter package installed, as it relies on the notebook format to generate the preview. Installation involves building the qlgenerator with Xcode and placing the resulting .qlgenerator bundle in the system‑wide /Library/QuickLook directory.

The implementation follows the standard Quick Look architecture for macOS, integrating with the operating system’s preview mechanism. It is distributed as a stable, core‑macOS component and can be complemented by the separate Jupyter App for launching notebooks directly from Finder.
