clipp is a single-header, MIT-licensed C++11/14/17 library for expressive command line argument parsing. It supports options, positional values, commands, nested alternatives, and automatic generation of usage lines and man pages.

Use cases

• parse command line arguments in a C++ program
• define CLI options and flags declaratively
• generate usage help and man pages from argument definitions
• handle subcommands and nested alternative argument groups
• validate argv input with custom value filters

When to choose

• you want a header-only, dependency-free argument parser for modern C++
• you need expressive interfaces with commands, alternatives, and joinable flags
• you want automatic usage/man-page generation

When to avoid

• your project is not C++ or predates C++11
• you need runtime plugin-style CLI extension or GUI configuration
• you prefer a full-featured framework with config files and subcommand scaffolding
