🧰 Daily C++ Modules

A curated collection of production-ready, lightweight, and zero-overhead C++ micro-modules for everyday development.

Instead of pulling in heavy, monolithic libraries for basic tasks, developers can simply copy a single folder from this repository and drop it straight into their project.

---

🎯 The Philosophy

• Zero Boilerplate: No heavy configurations, no external dependencies. Just pure C++23.
• Plug & Play: Designed natively with modern CMake (FILE_SET CXX_MODULES). Copy-paste and use via add_subdirectory.
• Modern Standards: Built from the ground up using C++20/C++23 features (import std;, std::expected, std::ranges, std::print) for modern safety and performance.
• Bite-Sized: Each directory solves exactly one specific domain problem beautifully and minimally.

📁 Repository Structure

Every tool is completely isolated in its own directory:

.
├── CMakeLists.txt         # Global build configuration (runs tests for all modules)
└── glm_lite/              # A plug-and-play micro-module
    ├── CMakeLists.txt     # Local CMake target definition
    ├── glm_lite.ixx       # C++23 module interface
    └── main.cpp           # Usage examples / Integration tests

---

🚀 Quick Integration Guide

To use any module (e.g., glm_lite) in your codebase:

1. Copy the module's directory into your project.
2. Link it in your CMakeLists.txt (requires CMake 3.28+):

cmake_minimum_required(VERSION 3.28)
project(YourApp LANGUAGES CXX)

# Include the copied module
add_subdirectory(glm_lite)

add_executable(app main.cpp)
target_link_libraries(app PRIVATE glm_lite)

3. Import it directly in your source code:

import glm_lite;

int main() {
    glm::vec3 velocity{0.0f, 9.8f, 0.0f};
    // Ready to use!
}

🛠️ Building & Testing Locally

To build the entire ecosystem and run validation tests for all modules simultaneously, ensure you have a compiler with robust C++23 module support (MSVC v143+, Clang 16+, or GCC 14+) and Ninja.

git clone https://github.com
cd daily-cpp-modules

# Configure using the Ninja generator (highly recommended for C++ Modules)
cmake -B build -G Ninja

# Build all modules and verification drivers
cmake --build build

🤝 Contributing

Have a tiny C++23 utility module that you use in every project? Feel free to open a Pull Request! Please ensure your module is fully self-contained, provides a CMakeLists.txt with FILE_SET CXX_MODULES, and includes a main.cpp for automated testing.
