Python/Typer

Typer is a library for building CLI applications based on Python type hints.

Built by the creator of FastAPI, Typer leverages Python 3.6+ type annotations to generate sophisticated command line interfaces with minimal boilerplate. It provides automatic help documentation, shell completion for bash/zsh/fish, and deep integration with VS Code and PyCharm. By using standard Python types like int, str, and Path, developers get full editor support and validation without learning a complex DSL (Domain Specific Language).
