jupyter_ydoc

jupyter_ydoc provides pycrdt-based data structures for various documents used in the Jupyter ecosystem. Built-in documents include:

YBlob: a generic immutable binary document.
YUnicode: a generic UTF8-encoded text document (YFile is an alias to YUnicode).
YNotebook: a Jupyter notebook document.

These documents are registered via an entry point under the "jupyter_ydoc" group as "blob", "unicode" (or "file"), and "notebook", respectively. You can access them as follows:

from jupyter_ydoc import ydocs

print(ydocs)
# {
#     'blob': <class 'jupyter_ydoc.yblob.YBlob'>,
#     'file': <class 'jupyter_ydoc.yfile.YFile'>,
#     'notebook': <class 'jupyter_ydoc.ynotebook.YNotebook'>,
#     'unicode': <class 'jupyter_ydoc.yunicode.YUnicode'>
# }

Which is just a shortcut to:

from importlib.metadata import entry_points
# for Python < 3.10, install importlib_metadata and do:
# from importlib_metadata import entry_points

ydocs = {ep.name: ep.load() for ep in entry_points(group="jupyter_ydoc")}

Or directly import them:

from jupyter_ydoc import YBlob, YUnicode, YNotebook

The "jupyter_ydoc" entry point group can be populated with your own documents, e.g. by adding the following to your package's pyproject.toml:

[project.entry-points.jupyter_ydoc]
my_document = "my_package.my_file:MyDocumentClass"

jupyter-server/jupyter_ydoc
