C++ CUI Frameworks

Overview

C++, as a primary language for systems programming and performance-critical applications, is ideal for developing high-performance CLI tools. Zero-overhead abstractions, fine-grained memory control, and native compilation enable building resource-efficient CLI applications. It's widely used for system utilities, development tools, and scientific computing tools.

Major Libraries

CLI11

A header-only CLI parser for modern C++ (C++11 and later). Features intuitive APIs, excellent error messages, and minimal dependencies.

Boost.Program_options

A mature and powerful command-line parsing library provided as part of the Boost libraries. It offers support for complex argument structures and configuration files.

Argparse

A C++17 library inspired by Python's argparse module. It provides a simple and familiar API.

TCLAP (Templatized C++ Command Line Parser)

A template-based header-only library. Features type-safe and extensible design.

Ncurses

A low-level library for building text user interfaces (TUI). It enables creating full-screen interactive applications.

Selection Guide

When to Choose CLI11

• Modern C++ projects (C++11 and later)
• Prefer header-only solutions
• Need intuitive and easy-to-use API
• Want to maintain minimal dependencies
• Excellent error messages and help generation

When to Choose Boost.Program_options

• Already using Boost
• Need complex argument processing
• Need configuration file support
• Prioritize maturity and stability
• Need comprehensive documentation

When to Choose Argparse

• C++17 and later projects
• Familiar with Python's argparse
• Prefer simple APIs
• Need lightweight solution
• Want to minimize learning cost

When to Choose TCLAP

• Leverage template metaprogramming
• Need highly customizable parsing
• Type safety is top priority
• Prefer header-only libraries
• Want to define custom argument types

When to Choose Ncurses

• Full-screen TUI applications
• Menu systems and dialog boxes
• Real-time updating displays
• Full keyboard and mouse control
• Terminal emulator development

Depending on project requirements, it's common to combine CLI11 or Boost.Program_options for argument parsing with Ncurses for interactive UI. You can build efficient CLI tools leveraging C++'s powerful type system and performance.
