tyro is a Python library that generates command-line interfaces and configuration objects from type-annotated Python functions, dataclasses, pydantic models, and attrs classes. It provides helptext generation, nested structures, subcommands, and shell completion while keeping arguments statically typed.

Use cases

• generate a CLI from a python function's type annotations
• parse command-line arguments into dataclasses or pydantic models
• build nested hierarchical config CLIs for ML training scripts
• add subcommands and shell completion to python scripts
• replace argparse boilerplate with typed config objects
• make script arguments IDE- and mypy-friendly

When to choose

• you want CLIs defined once from standard Python types, docstrings, and defaults
• you use dataclasses, pydantic, or attrs for configuration
• you need hierarchical configs or subcommands in research/engineering scripts
• static type checking of parsed arguments matters to you

When to avoid

• you need a full-featured CLI framework with rich interactive prompts
• your project is not Python
• you prefer YAML/dictionary-based configuration over typed arguments
