LuBox

LuBox is a Lua inspired scripting language for embedding in .NET applications.

Characteristics

1. Lightweigth API which is easy to embed.
2. Sandboxed with restricted access to IO and reflection.
3. Based on the Dynamic Language Runtime (DLR).

Examples

Call CLR Objects

var scriptEngine = new LuScriptEngine();
dynamic environment = scriptEngine.CreateStandardEnvironment();

environment.myVariable = "Hello";
scriptEngine.Execute("myVariable = myVariable:ToUpper()", environment);

Console.WriteLine(environment.myVariable);  // Output: HELLO

Call LuBox Function

var scriptEngine = new LuScriptEngine();
dynamic environment = scriptEngine.CreateStandardEnvironment();

scriptEngine.Execute(@"
    function Add(left, right)
        return left + right
    end", environment);

Console.WriteLine(environment.Add(1, 2));  // Output: 3

Performance and memory management

Since LuBox is implemented using the DLR the performance is typically close to regular .NET code after the first execution of a script. During the first execution however, or when rebinding due to changed types of variables, reflection is used and the execution time is usally in the order of milliseconds for a small script.

All objects allocated in a LuBox script are regular CLR objects and are collected by the .NET garbage collector.
