MoonSharp

http://www.moonsharp.org

A complete Lua solution written entirely in C# for the .NET, Mono, Xamarin and Unity3D platforms.

Features:

• 99% compatible with Lua 5.2 (with the only unsupported feature being weak tables support)
• Support for metalua style anonymous functions (lambda-style)
• Easy to use API
• Debugger support for Visual Studio Code (PCL targets not supported)
• Remote debugger accessible with a web browser and Flash (PCL targets not supported)
• Runs on .NET 3.5, .NET 4.x, .NET Core, Mono, Xamarin and Unity3D
• Runs on Ahead-of-time platforms like iOS
• Runs on IL2CPP converted code
• Runs on platforms requiring a .NET 4.x portable class library (e.g. Windows Phone)
• No external dependencies, implemented in as few targets as possible
• Easy and performant interop with CLR objects, with runtime code generation where supported
• Interop with methods, extension methods, overloads, fields, properties and indexers supported
• Support for the complete Lua standard library with very few exceptions (mostly located on the 'debug' module) and a few extensions (in the string library, mostly)
• Async methods for .NET 4.x targets
• Supports dumping/loading bytecode for obfuscation and quicker parsing at runtime
• An embedded JSON parser (with no dependencies) to convert between JSON and Lua tables
• Easy opt-out of Lua standard library modules to sandbox what scripts can access
• Easy to use error handling (script errors are exceptions)
• Support for coroutines, including invocation of coroutines as C# iterators
• REPL interpreter, plus facilities to easily implement your own REPL in few lines of code
• Complete XML help, and walkthroughs on http://www.moonsharp.org

The program and libraries are released under a 3-clause BSD license - see the license section.

Parts of the string library are based on the KopiLua project (https://github.com/NLua/KopiLua). Debugger icons are from the Eclipse project (https://www.eclipse.org/).

Usage

Use of the library is easy as:

double MoonSharpFactorial()
{
	string script = @"    
		-- defines a factorial function
		function fact (n)
			if (n == 0) then
				return 1
			else
				return n*fact(n - 1)
			end
		end

	return fact(5)";

	DynValue res = Script.RunString(script);
	return res.Number;
}
