CLI Arguments

Create Python CLI apps with little to no effort at all!

Adds features to Click: option groups, constraints, subcommand sections and help themes.

Plain Python functions as CLI commands without boilerplate

Turn functions into command-line interfaces

render CLI arguments (sub-commands friendly) defined by argparse module

Declarative CLI argument parser.

A strict CLI + library API to report untyped variables, arguments, and function returns in Python code

A High-performance, Generality, Humane Command Line Arguments Parser Library.

Command line argument to object parsing library for command line application development

A language-agnostic, TOML-based interface specification for anything runnable

Argument class <=> Human friendly cli

Run several Claude Code accounts side by side: separate CLAUDE_CONFIG_DIR directories, launchers, proxies, environment variables and arguments.

A python library for parsing multiple types of config files, envvars and command line arguments which takes the headache out of setting app configurations.

doc to argparse driven by docopt

Modern, declarative argument parser for Python 3.6+

Declarative CLI parser with type hints, config files, and environment variables - zero dependencies

specify command arguments in function decorator

Python library for creating and manipulating CLIs

ec - a cli interface for python modules.

Nested arguments parser

Build CLIs with reusable argparse parser classes.

Turn a dict of arguments into cli commands, ideal companion of docopt.

Zero-dependency Python CLI builders with a checkable correctness contract: definition bugs raise, user mistakes return values, parsing is pure.

Easily validate paths in command line arguments. To be used with argparse.

Automatically register fixtures for custom CLI arguments

A simple, clean alternative to argparse

Terminal UI for noeta, the open-source Claude Code-compatible coding agent: `noeta` with no arguments opens it.

A CLI framework for the Era of Agents: nothing is inferred, everything is declared. First-class support for Go, Python, and TypeScript (Python implementation)

Build powerful CLIs with simple idiomatic Python, driven by type hints. Not all arguments are bad.

Load and resolve complex configurations from files, environment variables and command line arguments. Keep your favorite CLI library.

Add the keys from a .toml file to your CLI as arguments. Their values default to the values in the .toml file.
