{"id":8238,"library":"ipynbname","title":"ipynbname","description":"The `ipynbname` library (current version 2025.8.0.0) provides a simple utility to retrieve the filename or full path of the current Jupyter notebook when executed within a browser-based Jupyter environment or VS Code. It was created to address the lack of a built-in, reliable method for accessing this information, especially for tasks like automating blog post publishing from notebooks.
