vre-jupyterlab-extension 0.1.2

VRE JupyterLab Extension with VRE DSL highlighting and notebook execution guard

VRE JupyterLab Extension

@virtmat/vre-jupyterlab-extension is a frontend-only JupyterLab 4 extension providing:

• CodeMirror 6 syntax highlighting for VRE DSL notebooks and .vm files
• execution guard for declarative workflows (executed-cell visuals + re-execution blocking)

Runtime Assumptions

• Linux-only development workflow
• Jupyter commands are executed through ./vre/bin/python -m jupyter
• Intended kernel integration target: vre-language with vre-middleware

Settings

This extension provides JupyterLab plugin settings via schema/plugin.json:

• enabled (default true): enables MIME synchronization and execution guard behavior.
• cellReadonlyDesignEnabled (default true): controls executed-cell readonly lock and visual treatment.

Commands

Open the Command Palette and run:

• VRE: Toggle Cell Readonly Design
• VRE: Toggle Extension

All toggles apply immediately and persist through refresh/restart via JupyterLab settings.

Development

• Install workspace dependencies: npm install
• Build package and bundled labextension assets: npm run -w @virtmat/vre-jupyterlab-extension build
• Run tests: npm run -w @virtmat/vre-jupyterlab-extension test

Python Packaging And Installation

This extension is packaged as a prebuilt JupyterLab extension so end users can install it directly from PyPI with pip install vre-jupyterlab-extension and use it immediately, without any Node or JupyterLab extension setup.

Build local wheel/sdist

From the package root (packages/vre-jupyterlab-extension):

• npm ci
• npm run build
• python -m pip install --upgrade build
• python -m build --wheel --sdist

Install via pip

Add to requirements.txt

Once published, add one of these lines in requirements.txt for vre-language or vre-middleware.

-- pip install vre-jupyterlab-extension==0.1.1 -- PyPI release: vre-jupyterlab-extension==0.1.1 -- GitHub tag build: vre-jupyterlab-extension @ git+https://github.com/<org>/<repo>.git@vre-jupyterlab-extension-v0.1.1#subdirectory=packages/vre-jupyterlab-extension -- GitLab tag build: vre-jupyterlab-extension @ git+https://gitlab.com/<group>/<repo>.git@vre-jupyterlab-extension-v0.1.1#subdirectory=packages/vre-jupyterlab-extension

Install dependencies as usual and the extension package is pulled in automatically.

Release Automation

GitHub

• Workflow file: .github/workflows/extension-publish.yml
• Trigger: push a tag (vre-jupyterlab-extension-vX.Y.Z or vX.Y.Z) or run manually.
• Required secrets:
  • PYPI_API_TOKEN for publishing to PyPI.
  • THE_GITHUB_PACKAGES_TOKEN for publishing to GitHub Packages.

GitLab

• CI file: .gitlab-ci.yml
• Trigger: tag pipeline.
• Publishes to GitLab Package Registry using CI_JOB_TOKEN.

Versioning And Updates

• Keep Python package version (setup.cfg) and npm package version (package.json) aligned.
• For downstream repos (vre-language, vre-middleware), pin exact versions in requirements.txt.
• To automate dependency bumps in downstream repos, enable Dependabot or Renovate for requirements.txt.

Note: JupyterLab does not auto-upgrade Python packages by itself. Upgrades are applied when your environment runs pip install -U ... or recreates the environment from updated lock/requirements files.
