Python Ecosystem

Part of src/cmds/ — see also docs/contributing/TECHNICAL.md

Specifics

• pytest_cmd.rs uses a state machine text parser (no JSON available from pytest)
• ruff_cmd.rs uses JSON for check mode (--output-format=json) and text filtering for format mode
• pip_cmd.rs auto-detects uv as a pip alternative and routes accordingly
• python -m pytest and python3 -m mypy are rewritten by the hook registry to rtk pytest / rtk mypy

Cross-command

• ruff_cmd is called by cmds/js/lint_cmd and cmds/system/format_cmd for Python projects
• mypy_cmd is called by cmds/js/lint_cmd when detecting Python type checking
