org.luaj.vm2.compiler
Class LuaC

java.lang.Object
  org.luaj.vm2.Lua
      org.luaj.vm2.compiler.LuaC

All Implemented Interfaces:

LoadState.LuaCompiler

public class LuaC
extends Lua
implements LoadState.LuaCompiler

Compiler for Lua.

Compiles lua source files into lua bytecode within a Prototype, loads lua binary files directly into aPrototype, and optionaly instantiates a LuaClosure around the result using a user-supplied environment.

Implements the LoadState.LuaCompiler interface for loading initialized chunks, which is an interface common to lua bytecode compiling and java bytecode compiling.

Teh LuaC compiler is installed by default by both the JsePlatform and JmePlatform classes, so in the following example, the default LuaC compiler will be used:

 LuaValue _G = JsePlatform.standardGlobals();
 LoadState.load( new ByteArrayInputStream("print 'hello'".getBytes()), "main.lua", _G ).call();
