## What it is
The official development repository of Lua, a powerful, lightweight, embeddable scripting language implemented in C. It includes the language interpreter, register-based virtual machine, standard libraries, and C API for embedding Lua into host applications.

## Use cases
- embed a scripting language into a C/C++ application
- script game logic and modding
- use as a configuration language
- rapid prototyping of small programs
- extend software with user-written plugins

## When to choose
- you need a tiny, fast, easily embeddable scripting runtime
- you want a simple language for configuration or extension scripting
- you need automatic memory management with a small footprint

## When to avoid
- you need a large standard library or ecosystem like Python's
- you want statically typed code
- you need heavy concurrency or native threading

## Facets
- artifact type: library
- maturity: stable
- function: interpreter, programming-language, embedded
- domain: programming-languages, developer-tools, embedded-systems
- platform: cross-platform, c, cpp, embedded
- tags: scripting-language, embeddable, virtual-machine, extension-language, configuration-language
