Add ruff linting and auto-format generated code#47
Merged
Conversation
- Add ruff configuration to pyproject.toml (line-length=120, E/F/I/W rules) - Fix all existing lint errors (unused imports, f-strings, import sorting) - Format all files with ruff format - Add transpailer/formatting.py utility that formats Python code via ruff - Integrate auto-formatting into code generation: LLM-generated Python code is now automatically formatted before being stored/returned in both stan_to_pymc and jax_pytorch_transpiler pipelines Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
ruff format adds a trailing newline, so use .strip() in assertion. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
