\n\n\n# **Juvio**: reproducible, dependency-aware, and Git-friendly Jupyter Notebooks.\n\n## 🚀 What It Does\n\n- 💡 **Inline Dependency Management**\n\n Install packages right from the notebook:\n\n ```python\n %juvio install numpy pandas\n ```\n\n Dependencies are saved directly in the notebook as metadata (PEP 723-style), like:\n ```python\n # /// script\n # requires-python = \"==3.10.17\"\n # dependencies = [\n # \"numpy==2.2.5\",\n # \"pandas==2.2.3\"\n # ]\n # ///\n ```\n\n- ⚙️ **Automatic Environment Setup**\n\n When the notebook is opened, Juvio installs the dependencies automatically in an ephemeral virtual environment (using `uv`), ensuring that the notebook runs with the correct versions of the packages and Python.\n\n- 📁 **Git-Friendly Format**\n\n Notebooks are converted on the fly to a script-style format using `# %%` markers, making diffs and version control painless:\n ```python\n # %%\n %juvio install numpy\n # %%\n import numpy as np\n # %%\n arr = np.array([1, 2, 3])\n print(arr)\n # %%\n ```\n\n## 🧑‍💻 How to Use\n\n> [!WARNING]\n> This project is currently in **early beta**. It may contain bugs and is subject to change.\n> Please [open an issue](../../issues) to report problems or suggest improvements.\n\n\n**1. Install Juvio:**\n\n```bash\npip install juvio\njupyter labextension enable juvio-frontend\n```\n\n**2. Make sure you have uv installed:**\n\nhttps://docs.astral.sh/uv/getting-started/installation/\n\n**3. Start JupyterLab and create a Juvio Notebook.**\n \n**4. Install necessary packages in the notebook and run your code**\n\n```python\n %juvio install ...\n ```\nDependencies are tracked, environments are reproducible, and your notebook stays Git-clean ✨\n\n**Known issue:** If you experience the error \"Notebook does not appear to be JSON\", try to lauch the jupyterlab with an additional argument:\n\n```bash\njupyter lab --ServerApp.jpserver_extensions=\"{'juvio': True}\"\n```\n\n## Why Use Juvio?\n\n- No additional lock or requirements files are needed\n- Guaranteed reproducibility\n- Cleaner Git diffs\n\n## Powered By\n\n- `uv` – ultra-fast Python package management\n- `PEP 723` – Python inline dependency standards\n- `jupytext`-like format for easy version control\n\n\n" }, { "path": "juvio/__init__.py",

You may use\n`yarn` or `npm` in lieu of `jlpm` below.\n\n```bash\n# Clone the repo to your local environment\n# Change directory to the juvio_frontend directory\n# Install package in development mode\npip install -e \".\"\n# Link your development version of the extension with JupyterLab\njupyter labextension develop . --overwrite\n# Rebuild extension Typescript source after making changes\njlpm build\n```\n\nYou can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.\n\n```bash\n# Watch the source directory in one terminal, automatically rebuilding when needed\njlpm watch\n# Run JupyterLab in another terminal\njupyter lab\n```\n\nWith the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).\n\nBy default, the `jlpm build` command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:\n\n```bash\njupyter lab build --minimize=False\n```\n\n### Development uninstall\n\n```bash\npip uninstall juvio_frontend\n```\n\nIn development mode, you will also need to remove the symlink created by `jupyter labextension develop`\ncommand. To find its location, you can run `jupyter labextension list` to figure out where the `labextensions`\nfolder is located. Then you can remove the symlink named `juvio_frontend` within that folder.\n\n### Testing the extension\n\n#### Frontend tests\n\nThis extension is using [Jest](https://jestjs.io/) for JavaScript code testing.\n\nTo execute them, execute:\n\n```sh\njlpm\njlpm test\n```\n\n#### Integration tests\n\nThis extension uses [Playwright](https://playwright.dev/docs/intro/) for the integration tests (aka user level tests).\nMore precisely, the JupyterLab helper [Galata](https://github.com/jupyterlab/jupyterlab/tree/master/galata) is used to handle testing the extension in JupyterLab.\n\nMore information are provided within the [ui-tests](./ui-tests/README.md) README.\n\n### Packaging the extension\n\nSee [RELEASE](RELEASE.md)\n" }, { "path": "juvio_frontend/RELEASE.md", "content": "# Making a new release of juvio_frontend\n\nThe extension can be published to `PyPI` and `npm` manually or using the [Jupyter Releaser](https://github.com/jupyter-server/jupyter_releaser).\n\n## Manual release\n\n### Python package\n\nThis extension can be distributed as Python packages. All of the Python\npackaging instructions are in the `pyproject.toml` file to wrap your extension in a\nPython package. Before generating a package, you first need to install some tools:\n\n```bash\npip install build twine hatch\n```\n\nBump the version using `hatch`. By default this will create a tag.\nSee the docs on [hatch-nodejs-version](https://github.com/agoose77/hatch-nodejs-version#semver) for details.\n\n```bash\nhatch version \n```\n\nMake sure to clean up all the development files before building the package:\n\n```bash\njlpm clean:all\n```\n\nYou could also clean up the local git repository:\n\n```bash\ngit clean -dfX\n```\n\nTo create a Python source package (`.tar.gz`) and the binary package (`.whl`) in the `dist/` directory, do:\n\n```bash\npython -m build\n```\n\n> `python setup.py sdist bdist_wheel` is deprecated and will not work for this package.\n\nThen to upload the package to PyPI, do:\n\n```bash\ntwine upload dist/*\n```\n\n### NPM package\n\nTo publish the frontend part of the extension as a NPM package, do:\n\n```bash\nnpm login\nnpm publish --access public\n```\n\n## Automated releases with the Jupyter Releaser\n\nThe extension repository should already be compatible with the Jupyter Releaser.\n\nCheck out the [workflow documentation](https://jupyter-releaser.readthedocs.io/en/latest/get_started/making_release_from_repo.html) for more information.\n\nHere is a summary of the steps to cut a new release:\n\n- Add `ADMIN_GITHUB_TOKEN`, `PYPI_TOKEN` and `NPM_TOKEN` to the [Github Secrets](https://docs.github.com/en/actions/security-guides/encrypted-secrets) in the repository\n- Go to the Actions panel\n- Run the \"Step 1: Prep Release\" workflow\n- Check the draft changelog\n- Run the \"Step 2: Publish Release\" workflow\n\n## Publishing to `conda-forge`\n\nIf the package is not on conda forge yet, check the documentation to learn how to add it: https://conda-forge.org/docs/maintainer/adding_pkgs.html\n\nOtherwise a bot should pick up the new version publish to PyPI, and open a new PR on the feedstock repository automatically.\n" }, { "path": "juvio_frontend/babel.config.js", "content": "module.exports = require('@jupyterlab/testutils/lib/babel.config');\n" }, { "path":

[Playwright](https://playwright.dev/docs/intro) test runner\nand [Galata](https://github.com/jupyterlab/jupyterlab/tree/master/galata) helper.\n\nThe Playwright configuration is defined in [playwright.config.js](./playwright.config.js).\n\nThe JupyterLab server configuration to use for the integration test is defined\nin [jupyter_server_test_config.py](./jupyter_server_test_config.py).\n\nThe default configuration will produce video for failing tests and an HTML report.\n\n> There is a new experimental UI mode that you may fall in love with; see [that video](https://www.youtube.com/watch?v=jF0yA-JLQW0).\n\n## Run the tests\n\n> All commands are assumed to be executed from the root directory\n\nTo run the tests, you need to:\n\n1. Compile the extension:\n\n```sh\njlpm install\njlpm build:prod\n```\n\n> Check the extension is installed in JupyterLab.\n\n2. Install test dependencies (needed only once):\n\n```sh\ncd ./ui-tests\njlpm install\njlpm playwright install\ncd ..\n```\n\n3. Execute the [Playwright](https://playwright.dev/docs/intro) tests:\n\n```sh\ncd ./ui-tests\njlpm playwright test\n```\n\nTest results will be shown in the terminal. In case of any test failures, the test report\nwill be opened in your browser at the end of the tests execution; see\n[Playwright documentation](https://playwright.dev/docs/test-reporters#html-reporter)\nfor configuring that behavior.\n\n## Update the tests snapshots\n\n> All commands are assumed to be executed from the root directory\n\nIf you are comparing snapshots to validate your tests, you may need to update\nthe reference snapshots stored in the repository. To do that, you need to:\n\n1. Compile the extension:\n\n```sh\njlpm install\njlpm build:prod\n```\n\n> Check the extension is installed in JupyterLab.\n\n2. Install test dependencies (needed only once):\n\n```sh\ncd ./ui-tests\njlpm install\njlpm playwright install\ncd ..\n```\n\n3. Execute the [Playwright](https://playwright.dev/docs/intro) command:\n\n```sh\ncd ./ui-tests\njlpm playwright test -u\n```\n\n> Some discrepancy may occurs between the snapshots generated on your computer and\n> the one generated on the CI. To ease updating the snapshots on a PR, you can\n> type `please update playwright snapshots` to trigger the update by a bot on the CI.\n> Once the bot has computed new snapshots, it will commit them to the PR branch.\n\n## Create tests\n\n> All commands are assumed to be executed from the root directory\n\nTo create tests, the easiest way is to use the code generator tool of playwright:\n\n1. Compile the extension:\n\n```sh\njlpm install\njlpm build:prod\n```\n\n> Check the extension is installed in JupyterLab.\n\n2. Install test dependencies (needed only once):\n\n```sh\ncd ./ui-tests\njlpm install\njlpm playwright install\ncd ..\n```\n\n3. Start the server:\n\n```sh\ncd ./ui-tests\njlpm start\n```\n\n4. Execute the [Playwright code generator](https://playwright.dev/docs/codegen) in **another terminal**:\n\n```sh\ncd ./ui-tests\njlpm playwright codegen localhost:8888\n```\n\n## Debug tests\n\n> All commands are assumed to be executed from the root directory\n\nTo debug tests, a good way is to use the inspector tool of playwright:\n\n1. Compile the extension:\n\n```sh\njlpm install\njlpm build:prod\n```\n\n> Check the extension is installed in JupyterLab.\n\n2.
