Python Package

The vscode_common_python_lsp Python package provides server-side utilities shared across all five extensions: path resolution, context managers, tool execution runners, JSON-RPC process management, and the LSP server factory.

Development

cd python
pip install -e ".[dev]"
pytest tests/

TypeScript Package

The vscode-common-python-lsp TypeScript package provides VS Code client-side utilities: extension activation, server lifecycle, settings management, Python interpreter resolution, and logging.

Development

cd typescript
npm install
npm run build
npm test
