Positron Notebooks

关于

Provides specialized guidance and automated workflows for engineering Positron Notebooks, a custom feature-flagged React implementation that coexists with VS Code's standard notebook experience. It offers deep integration for managing notebook cell behavior, complex selection states through finite state machines, and context-key-scoped command systems. Developers can leverage this skill to navigate the architecture of kernel-notebook integration, troubleshoot execution issues, and implement UI components driven by VS Code observables while ensuring feature-flag compliance and upstream compatibility.

主要功能

• Automated testing and validation scripts for E2E and unit test suites
• Management of notebook cell behavior including execution, rendering, and editing
• Navigation of the state-machine-driven selection and focus system
• Implementation patterns for cell action commands and context key scoping
• Standardized debugging workflows for notebook-kernel integration and webview-based output rendering
• 3,802 GitHub stars

使用场景

• Extending the notebook command registry and context-sensitive menus
• Developing new React-based cell components or UI features for the Positron IDE
• Troubleshooting complex cell execution bugs and kernel communication issues
