Rix - Minimal Modern C++ Standard Library

Rix is a lightweight and modern collection of essential utilities

designed for C++20 and beyond.
It serves as a modular, header-only, minimal standard library, ideal for:

• Modern C++ development
• Embedded / lightweight projects
• High-performance frameworks like Vix.cpp
• Developers who want a clean, consistent, simplified alternative to the STL

Each module is provided as a standalone repository, while rix (the umbrella project) offers a unified interface for convenience.

Installation

rix modules are header-only and can be included individually or via the umbrella rix CMake project.

Example using CMake:

# Add rix umbrella as a subdirectory
add_subdirectory(path/to/rix)
target_link_libraries(my_project PRIVATE rix::rix)

Include modules in your C++ code:

#include <rix/io/file.h>
#include <rix/json/json.h>
#include <rix/net/tcp.h>
#include <rix/chrono/timer.h>

---

Usage Example

#include <rix/io/file.h>
#include <rix/json/json.h>
#include <rix/net/tcp.h>
#include <rix/chrono/timer.h>

int main() {
    rix::io::File f("test.txt", rix::io::Mode::Write);
    f.write("Hello Rix!\n");

    rix::json::Json j;
    j["ok"] = true;

    rix::net::TcpClient sock("example.com", 8080);
    sock.write("PING\n");

    rix::chrono::Timer t;
    t.sleep_ms(1000);
}
