<strong><code>tyro.cli()</code></strong> is a tool for generating CLI
interfaces from type-annotated Python.

We can define configurable scripts using functions:

<br />
<br />
Or instantiate configs defined using tools like `dataclasses`, `pydantic`, and `attrs`:
<br />
<img width="836" height="334" alt="image" src="https://github.com/user-attachments/assets/2c27065d-073e-4c59-9df9-20d153b4a33b" />
<br />

Other features include helptext generation, nested structures, subcommands, and
shell completion. For examples and the API reference, see our
[documentation](https://brentyi.github.io/tyro).

### Why `tyro`?

1. **Define things once.** Standard Python type annotations, docstrings, and default values are parsed to automatically generate command-line interfaces with nice helptext.

2. **Static types.** Unlike tools dependent on dictionaries, YAML, or dynamic
   namespaces, arguments populated by `tyro` are better undestood by IDEs and
   language servers, as well as static checking tools like `pyright` and `mypy`.

3. **Modularity.** `tyro` supports hierarchical configurations, which make it
   easy to decentralize definitions, defaults, and documentation.

### In the wild

`tyro` is designed to be lightweight for throwaway scripts, while
improving maintainability for larger projects. Examples:

### Alternatives

`tyro` is opinionated. If any design decisions don't make sense, feel free to
file an issue!

You might also consider one of many alternative libraries. Some that we
like:

- [cappa](https://github.com/dancardin/cappa) offers a similar core feature
  set but with very different ergonomics. It looks polished and well-maintained!
- [cyclopts](https://github.com/BrianPugh/cyclopts) and
  [defopt](https://defopt.readthedocs.io/) has very comprehensive type
  annotation support and a heavier emphasis on subcommand generation.
- [simple-parsing](https://github.com/lebrice/SimpleParsing) and
  [jsonargparse](https://github.com/omni-us/jsonargparse) provide deeper
  integration with configuration file formats like YAML and JSON.
- [clipstick](https://github.com/sander76/clipstick), which focuses on
  simplicity + generating CLIs from Pydantic models.
- [datargs](https://github.com/roee30/datargs) provides a minimal API for
  dataclasses.
- [fire](https://github.com/google/python-fire) and
  [clize](https://github.com/epsy/clize) support arguments without type
  annotations.

There are also some options that directly extend `tyro`:

- [mininterface](https://github.com/CZ-NIC/mininterface) simultaneously generates
  GUI, TUI, web, CLI, and file-based program configuration.
- [manuscript](https://github.com/stllfe/manuscript) generates CLI interfaces from
  a simple block of configuration variables.

We also have some notes on `tyro`'s design goals and other alternatives in the
docs [here](https://brentyi.github.io/tyro/goals_and_alternatives/).
