## What it is
Runtime-Compiled C++ (RCC++) is a C++ library and sample project that lets developers recompile and swap C++ code while a program is running, preserving object state via simple in-memory serialization. It is aimed primarily at game development to shorten iteration times, without scripting, VMs, or external tools.

## Use cases
- edit c++ code while the program is running
- shorten iteration times in game development
- hot reload c++ modules without restarting the app
- preserve object state across runtime code changes
- rapidly iterate on game ai code
- live coding in c++ with visual studio or xcode

## When to choose
- you need fast compile-edit-test loops in a C++ game or simulation
- you want live code changes without scripting languages or VMs
- you develop on Windows, Linux, or macOS with MSVC, GCC, or Clang

## When to avoid
- you want end users of a shipped binary to compile modifications
- your project cannot tolerate runtime compilation infrastructure
- you need a license with explicit terms (the repo has no license file)

## Facets
- artifact type: library
- maturity: active
- function: compiler, developer-tools, build-tool, serialization
- domain: developer-tools, cross-platform
- platform: windows, cpp, cross-platform
- tags: live-coding, runtime-compilation, rccpp, iteration-time, hot-reload, gamedev, game-development, linux, macos
