SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill streamlines the development of high-performance C++ applications by providing expert guidance on modern C++ standards (C++20/C++23), build systems like CMake, and best practices for memory management and concurrency.

Core Features & Use Cases

  • Modern C++ Standards: Leverage C++20/C++23 features like Concepts, Ranges, Modules, std::expected, and std::print.
  • Build Systems: Master CMake for efficient project configuration and dependency management.
  • Resource Management: Implement robust RAII patterns and smart pointer usage for memory safety.
  • Concurrency: Utilize std::jthread, std::latch, and std::barrier for safe multithreaded applications.
  • Use Case: Develop a high-performance backend service using C++23, ensuring memory safety with smart pointers, efficient build configuration with CMake, and robust error handling with std::expected.

Quick Start

Use the moai-lang-cpp skill to generate a CMakeLists.txt file for a C++23 project with FetchContent for the fmt library.

FAQPage Schema
How do I set up a CMakeLists.txt for a C++23 project with FetchContent?

To configure a C++23 project with CMake FetchContent, you specify the C++ standard, enable required compiler features, and use FetchContent_Declare to pull dependencies like the fmt library for efficient project configuration.

What is the best way to ensure memory safety in modern C++ development?

Memory safety in modern C++ is primarily ensured by implementing RAII patterns and using smart pointers, which automatically manage resource allocation and deallocation, preventing leaks and dangling pointers in high-performance applications.

How do I use std::jthread and std::latch for safe multithreaded C++ applications?

For safe multithreaded C++ applications, utilize std::jthread for automatic joining and std::latch or std::barrier to synchronize threads, preventing common concurrency errors like deadlocks or premature thread termination.

When should I use std::expected instead of exceptions for error handling?

Use std::expected for error handling in modern C++ when you need explicit, value-based error propagation without the overhead of stack unwinding, ensuring robust error management in high-performance backend services.

Does this guidance cover C++20 Concepts and Ranges for STL usage?

Yes, this guidance covers leveraging C++20/C++23 features including Concepts for template constraints and Ranges for composable STL operations, streamlining high-performance system software and embedded systems development.

Can I use this for embedded systems development or is it only for backend services?

You can use this for embedded systems development as well as high-performance backend services, games, and system software, covering essential modern C++ standards, memory safety, and build system configuration.
