背景

当你需要Core2.X+Lua的时候,就可以往下看了…

MoonSharp

其实moonsharp(Lua5.2环境)的测评和性能不高,但是如果仅仅是能用的要求…就可以继续往下看

MoonSharp Build Status Build Status

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

License

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;
}

我的实现

我使用了core-mvc+moonsharp,核心代码:
DemoController.cs

using Microsoft.AspNetCore.Mvc;
using MoonSharp.Interpreter;
using System;

namespace MyCore.Controllers
{
    [Route("api/demo")]
    [ApiController]
    public class DemoController : Controller
    {
        [Route("test")]
        public string Test(string test)
        {
            return "Test:" + test;
        }

        [Route("getlua")]
        public string GetLua()
        {
            Console.WriteLine("GetLua...");
            Script script = new Script();
            script.DoString(@"
            function test(a)
                return a*3
            end
            ");
            DynValue luaFunction = script.Globals.Get("test");
            DynValue res = script.Call(luaFunction,5);
            return "GetLua:"+res.Number;
        }
    }
}
