Jupyter document structures for collaborative editing using Yjs/pycrdt

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_ydoc's Issues

Can't package jupyter-ydoc 1.1.1 with jupyter-collaboration 1.2.1

Hi,

openSUSE rpm package maintainer for the jupyter ecosystem here.

I am at an impasse:

1. jupyter-collaboration v2 and jupyter-ydoc v2 require pycrdt which is declared to be not ready for production yet
2. jupyter-collaboration v1.2.1 requires

   "jupyter_ydoc>=1.0.1,<2.0.0", 
   "ypy-websocket>=0.12.1,<0.13.0",
   

3. jupyter-ydoc 1.1.1 requires ypy-websocket >=0.8.3,<0.9.0 for testing.

Number 2 and 3 conflict with each other. Any advice?

Use nbformat when creating an empty cell

Problem

When we set the content of a YNotebook from some source, we create an empty cell if there was no cell originally.

Proposed Solution

We should probably use nbformat for that.

Notebook cell execution

Problem

Today at the Jupyter Server meeting we talked about notebook restoration, where RTC could be a solution (see jupyter-server/jupyter_server#900). In that solution, the frontend just displays live changes to the notebook shared model. But currently, a notebook cell execution is either None or an integer greater than 0, so there is no way to show that a cell is executing.

Proposed Solution

We could encode the "cell executing" state in the execution count, for instance as "*". I think it could even be part of nbformat, because it brings some information about the state of the notebook at the time it was saved.

Allow users to provide an external `ydoc` to `YDocument`

Problem

The constructor of YDocument is empty since the internal YJS doc is created by the class. It would be useful if users can provide an existing ydoc to the YDocument constructor.

Proposed Solution

Update the YDocument constructor signature to allow overriding the ydoc property.

Additional context

• This would help ypywidgets project to create frontend widgets.

y-py v0.5.5 from conda-forge breaks ydoc

Due to the problem with the y-py aarch64 build (here: y-crdt/ypy#119). We published a new build of ypy v0.5.5 in conda-forge. This new build includes y-crdt/ypy#102, which changes the return type of the to_json and breaks jupyter_ydoc.

Task exception was never retrieved

The error above is caused by

jupyter_ydoc/jupyter_ydoc/ynotebook.py

Line 194 in c9db1e7

meta = self._ymeta.to_json()

, because when installing y-py v0.5.5 from conda-forge, the to_json method returns a string.

Support cell.source as [list, of, strings]

Description

https://nbformat.readthedocs.io/en/latest/format_description.html#cell-types

There are a few basic cell types for encapsulating code and text. All cells have the following basic structure:

{
"cell_type" : "type",
"metadata" : {},
"source" : "single string or [list, of, strings]",
}

In Jupyterlab3.x, cell.source is [list, of, strings], which causes

  File "/opt/conda/lib/python3.9/site-packages/jupyter_ydoc/ydoc.py", line 30, in source
    return self.set(value)
  File "/opt/conda/lib/python3.9/site-packages/jupyter_ydoc/ydoc.py", line 197, in set
    self._ycells.extend(t, [self.create_ycell(cell) for cell in cells])

  File "/opt/conda/lib/python3.9/site-packages/jupyter_ydoc/ydoc.py", line 127, in create_ycell
    cell["source"] = Y.YText(cell["source"])
TypeError: argument 'init': 'list' object cannot be converted to 'PyString'

Casting numbers

Could we add code comments for the reason to cast number float <-> int? Like at

jupyter_ydoc/jupyter_ydoc/ydoc.py

Line 89 in 043163b

cast_all(cell, float, int)

Is it possible to reduce the scope of conversion to reduce the load and avoid troubles? At first glance, that cast sounds like a source of hard-to-find errors in the future especially when applying it to cell serialization.

Improve observe API

The observe API is not aligned with what is defined in the TypeScript API; in particular I don't see how a callback can determine which parts (like ycells, ymeta, ystate for YNotebook) has triggered the event without testing for target (not knowing for sure which are the available event targets).

jupyter_ydoc/jupyter_ydoc/ydoc.py

Lines 74 to 77 in 23800c0

	def observe(self, callback):
	self.unobserve()
	self._subscriptions[self._ystate] = self._ystate.observe(callback)
	self._subscriptions[self._ysource] = self._ysource.observe(callback)

jupyter_ydoc/jupyter_ydoc/ydoc.py

Lines 192 to 196 in 23800c0

	def observe(self, callback):
	self.unobserve()
	self._subscriptions[self._ystate] = self._ystate.observe(callback)
	self._subscriptions[self._ymeta] = self._ymeta.observe(callback)
	self._subscriptions[self._ycells] = self._ycells.observe_deep(callback)

For reference, in the frontend, the events are pipe through a dictionary with key highlighting the event target (source, cells,...); see for example: https://github.com/jupyterlab/jupyterlab/blob/c1126de609dd3bcf585a00ecaa8a1104906dd8e7/packages/shared-models/src/api.ts#L488

ModuleNotFoundError: No module named 'pkg_resources'

Description

With jupyter_ydoc==0.2.0 there seems to be an issue with missing pkg_resources:

Reproduce

This was noticed in jupyter/notebook#6539 (comment), with this example run: https://github.com/jupyter/notebook/actions/runs/3145280672/jobs/5112365511

In that case notebook uses hatch as the build backend but triggers commands from JupyterLab to build the extension, which probably explains why it hits the jupyter_ydoc path since there is a top-level import.

Expected behavior

Probably there should not be a dependency on pkg_resources?

Y bridge between YDocs

Problem

One document may have different YDoc structures, e.g. a Jupyter notebook can be opened in JupyterLab as a notebook (and it will be shown nicely with cells etc.) or as a plain text document. While the text document has a relatively simple YDoc, with only a YText for the whole content, the notebook has a YArray for cells, a YMap for metadata, etc. This finer-grained structure allows to observe changes to e.g. a cell source only, and react accordingly.
While a YDoc can be synced with another YDoc of the same structure, for instance between two browsers showing the same notebook, the same document cannot be synced when opened as two different YDocs (e.g. in text/as a notebook) in the same JupyterLab.

Proposed Solution

We could create a "Y bridge", that would make syncing the two "incompatible" YDocs possible. Something that observes changes to a YDoc and translates them to the other. It will require some interpretation, e.g. when changing the cell source in a text document, we need to do the update in the appropriate cell structure in a notebook.

YNotebook error with y-py v0.6.0

Description

Trying to instantiate and set a YNotebook fails with jupyter_ydoc v0.3.2. Downgrading y-py from v0.6.0 to v0.5.5 fixes the issue.

Reproduce

1. pip install jupyter_ydoc==0.3.2
2. Execute the following Python code:

from jupyter_ydoc import YNotebook

nb = {"cells": []}

ynb = YNotebook()
ynb.set(nb)

4. See error:

Err(PyErr { type: <class 'y_py.MultipleIntegrationError'>, value: MultipleIntegrationError("Cannot integrate a nested Ypy object because is already integrated into a YDoc: {'id': '1d9dbf0a-34ac-46a4-bef9-101fb83d4cea', 'cell_type': 'code', 'execution_count': 1, 'metadata': YMap({}), 'outputs': YArray([]), 'source': YText(1 + 1)}"), traceback: None })

Expected behavior

No error.

Is it worth creating a `CONTRIBUTING.md`

I noticed there are no contributing instructions.

Would it be worth adding some basics (installation/building/linting expectations, etc)?

Allow for document-agnostic undo/redo

Problem

Currently, data that can be undone (using an undo manager) is not specified. For instance, the content of a YFile is stored in a Text root type under "source", and the cells of a YNotebook are stored in an Array root type under "cells". This prevent an undo manager to operate on a document in an agnostic way, i.e. without knowing what it is manipulating. Indeed, the undo manager needs to be scoped to one or several shared types (see here).

Proposed Solution

We could either:

• have all the undoable data of a shared document under a root type, for instance "data". For a notebook, that would look like:

{
  "meta": {},
  "data": {
    "cells": []
  },
}

That would be a breaking change.

• have a special field (maybe under the "state" root Map), that would list the root types that can be undone. For a notebook, that would look like this:

{
  "state": {
    "undo": "cells"
  }
}

That would be an additive change.

Additional context

This is particularly useful in the context of a document timeline explorer.

Invalid notebook in test expectation

Note: the underlying issue might be the cause of jupyter/notebook#6828.

The nb0.ipynb notebook used as an expectation in tests is invalid and does not even render on GitHub:

It is used in this test:

jupyter_ydoc/tests/test_ypy_yjs.py

Lines 51 to 62 in 1ec81ff

	@pytest.mark.asyncio
	@pytest.mark.parametrize("yjs_client", "0", indirect=True)
	async def test_ypy_yjs_0(yws_server, yjs_client):
	ydoc = Y.YDoc()
	ynotebook = YNotebook(ydoc)
	websocket = await connect("ws://localhost:1234/my-roomname")
	WebsocketProvider(ydoc, websocket)
	nb = stringify_source(json.loads((files_dir / "nb0.ipynb").read_text()))
	ynotebook.source = nb
	ytest = YTest(ydoc, 3.0)
	await ytest.change()
	assert ytest.source == nb

And contains two code cells with id set to null:

{
    "cells": [
        {
            "cell_type": "code",
            "source": [
                "print('Hello, World!')"
            ],
            "metadata": {},
            "outputs": [],
            "execution_count": null,
            "id": null
        },
        {
            "cell_type": "code",
            "source": "print('Hello, World!')",
            "metadata": {},
            "outputs": [],
            "execution_count": null,
            "id": null
        }
    ],
    "metadata": {
        "kernelspec": {
            "display_name": "Python 3 (ipykernel)",
            "language": "python",
            "name": "python3"
        },
        "language_info": {
            "codemirror_mode": {
                "name": "ipython",
                "version": 3
            },
            "file_extension": ".py",
            "mimetype": "text/x-python",
            "name": "python",
            "nbconvert_exporter": "python",
            "pygments_lexer": "ipython3",
            "version": "3.10.2"
        }
    },
    "nbformat": 4,
    "nbformat_minor": 5
}

While execution_count can be null, id cannot, compare specification:

Code cells are the primary content of Jupyter notebooks. They contain source code in the language of the document’s associated kernel, and a list of outputs associated with executing that code. They also have an execution_count, which must be an integer or null.

Since the 4.5 schema release, all cells have an id field which must be a string of length 1-64 with alphanumeric, -, and _ as legal characters to use. These ids must be unique to any given Notebook following the nbformat spec.

And schema:

"execution_count": {
  "description": "The code cell's prompt number. Will be null if the cell has not been run.",
  "type": ["integer", "null"],
  "minimum": 0
}

"definitions": {
    "cell_id": {
      "description": "A string field representing the identifier of this particular cell.",
      "type": "string",
      "pattern": "^[a-zA-Z0-9-_]+$",
      "minLength": 1,
      "maxLength": 64
    }
}

YBaseDoc as abstract class

Should we use an abstract class instead of:

jupyter_ydoc/jupyter_ydoc/ydoc.py

Lines 41 to 48 in ac934c3

	def get(self):
	raise RuntimeError("Y document get not implemented")
	def set(self, value):
	raise RuntimeError("Y document set not implemented")
	def observe(self, callback):
	raise RuntimeError("Y document observe not implemented")

At least the Python practice is such case advice to raise the more specific NotImplementedError (that derives from RunTimeError).

Dependency on ypy-websocket

Hello.

Why is the dependency on ypy-websocket pinned to the old version?

jupyter_ydoc/pyproject.toml

Line 34 in 42dd437

"ypy-websocket >=0.3.1,<0.4.0",

I'm packaging JupyterLab into Fedora and it seems that the packages work together also with the latest version of the ypy-websocket 0.8.2.

Undo/redo does not scroll to selection

Description

This is one of the most frustrating things for me when using JupyterLab and it prevents me from working productively with larger files - see jupyterlab/jupyterlab#15102

Reproduce

See jupyterlab/jupyterlab#15102

Expected behavior

Editor scrolls on undo/redo if the new selection is outside of the viewport.

Context

This was just fixed in y-codemirror.next: yjs/y-codemirror.next#34 but jupyter_ydoc does not use that and has its own integration of undo manager.

Add YDirectory

Problem

Currently in RTC mode, directories are handled differently than files. The latter use the YDocWebSocketHandler, while the former use HTTP.
With jupyterlab/jupyterlab#13527, JupyterLab drives will use the y-websocket, that will allow to drop the HTTP API for directories.

Proposed Solution

I think we should create a new YDirectory document for these "collaborative drives". It will allow listing directories, renaming/deleting files and directories, etc.

Get/set notebook cell

Problem

Currently, a notebook source can only be changed/retrieved globally through its source attribute, but it could be interesting to be able to change/retrieve only a particular cell.

Proposed Solution

Add YNotebook.set_cell(index, cell) and YNotebook.get_cell(index).

Additional context

In jupyter-server/jupyverse#191 we are experimenting with a kernels REST API that allows to execute and update a cell from the back-end, where this could be useful.

Tests

As mentioned in this comment, we should create tests that:

• start from a source (text/JSON),
• create a Ypy document from it,
• read the Y document using Yjs,
• generate the source back,
• check that the sources are identical.

Add type/version information to Y documents

Problem

Currently, a YFile represents a plain text document. This seems to assume that a document with no particular structure should be of text type, while it could also be binary.
Even a YNotebook seems to assume that a notebook will always have the JSON type that we know, but it might not be the case anymore in the future (Jupyter notebooks could evolve towards a Markdown-based format).
These two Y documents were derived from jupyter-server, where we have a file model and a notebook model. The file model can be of type text or binary, but in the latter case it is base64-encoded. The notebook model has a JSON type.

Proposed Solution

I think we should not stick to what jupyter-server is doing, and have:

• YText: a plain text document.
• YBytes: a binary document.
• YJsonNotebook: a JSON-encoded notebook.
• YMdNotebook: a Markdown-encoded notebook.

Or include the type/version in the Y document instantiation. For instance, keep YFile and YNotebook but instantiate with:

• YFile("text")/YFile("bytes")
• YNotebook(version="5.7.1")

Thoughts?

Notebook code cell stream output schema

Problem

Currently, a notebook code cell defines outputs as an untyped YArray where we store the output list as-is. Each item of the outputs can be of different type:

• stream,
• display_data,
• execute_result,
• error.

But for a stream output type, the structure looks like this (for e.g. an stdout stream):

{
  "output_type": "stream",
  "name": "stdout",
  "text": ["some", "content"]
}

Since the "text" list can be appended to as the cell is executing (by the kernel printing to stdout), the current situation is not great because we cannot observe changes to "text": the whole output in the YArray has to be set, with just that new item in the "text".

Proposed Solution

We should define an output of type stream as follows:

YMap[
  "output_type": "stream",
  "name": str,
  "text": YArray[str]
]

0.3.4: pytest is failing because missing `node_modules/y-websocket/package.json` file

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation

• install .whl file in </install/prefix>
• run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Unable to open Notebook without metadata

Description

I am getting the following:

    Traceback (most recent call last):
      File "/home/martinrenou/micromamba/envs/glue-lab/lib/python3.11/site-packages/tornado/websocket.py", line 944, in _accept_connection

                 ~~~~^^^^^^^^^^^^
    KeyError: 'metadata'

Leading to not being able to open the Notebook (it's an empty area on Jupyterlab)

Add model version

Problem

If we ever want to change or extend the document models, they will become incompatible when collaborating with others (independent of which nbformat they are using). We should attach some sort of version to document models and disallow editing of documents that use other models.

From jupyterlab/jupyterlab#2475

Proposed Solution

Add version class attribute to the document.

Flaky test failure: Duplicate cells due to lingering node processes

Description

test_ypy_yjs_0[0] randomly fails in comparing the generated code cells to the reference. This behavior is flaky, though. Sometimes there is only one cell, sometimes there are multiple duplicates:

Reproduce

wget https://github.com/jupyter-server/jupyter_ydoc/archive/refs/tags/v1.0.2.tar.gz
tar xf v1.0.2.tar.gz
pushd jupyter_ydoc-1.0.2
pushd javascript
yarn
yarn build
popd
python3 -m venv testenv
testenv/bin/pip install '.[test]'
for i in 1 2 3 4 5 6; do
  testenv/bin/python -m pytest -vv
done

Result:
