## What it is
UniLua is a pure C# implementation of the Lua 5.2 language, focused on compatibility with Unity3D. It implements the core language features including coroutines and metatables, with some standard libraries partially implemented or omitted.

## Use cases
- embed a Lua scripting engine in a Unity game
- run Lua 5.2 scripts from C# code
- call C# functions from Lua scripts
- script game logic in Lua on Unity3D
- use coroutines and metatables in a managed Lua interpreter

## When to choose
- you need a pure C# Lua interpreter with no native dependencies in Unity
- you want Lua 5.2 language semantics including coroutines and metatables
- you cannot use P/Invoke or native Lua libraries in your target platform

## When to avoid
- you need full standard library coverage such as IO or OS libs
- you rely on __gc metamethods, weak tables, or full userdata
- you need maximum Lua runtime performance in performance-critical code

## Facets
- artifact type: library
- maturity: maintenance
- function: interpreter, programming-language
- domain: programming-languages, parsers
- platform: cross-platform, game-engine
- tags: lua, c-sharp, unity3d, scripting, lua-5-2, game-development
