argparse
A single-header argument parsing library for modern C++17 applications.
What is argparse?
argparse is a single-header argument parsing library for modern C++ that simplifies handling command-line arguments in applications. It provides a declarative API to define positional arguments, optional flags, subcommands, and complex parsing logic, replacing manual argc/argv processing with a robust, type-safe solution.
C++ developers building command-line tools, utilities, or applications that require sophisticated argument parsing, especially those using C++17 or newer standards.
Developers choose argparse for its ease of use, modern C++ design, and comprehensive feature set—including subcommands, custom actions, and automatic help—all in a single header with no external dependencies.
