Class JsePlatform

java.lang.Object
com.prineside.luaj.lib.jse.JsePlatform
public class JsePlatform extends Object
The class is a convenience class to standardize how globals tables are initialized for the JSE platform.

It is used to allocate either a set of standard globals using standardGlobals() or debug globals using debugGlobals()

A simple example of initializing globals and using them from Java is: 

 
 Globals globals = JsePlatform.standardGlobals();
 globals.get("print").call(LuaValue.valueOf("hello, world"));

Once globals are created, a simple way to load and run a script is: 

 
 globals.load( new FileInputStream("main.lua"), "main.lua" ).call();

although require could also be used: 

 
 globals.get("require").call(LuaValue.valueOf("main"));
For this to succeed, the file "main.lua" must be in the current directory or a resource.

The standard globals will contain all standard libraries plus luajava:

In addition, the LuaC compiler is installed so lua files may be loaded in their source form.

The debug globals are simply the standard globals plus the debug library DebugLib.

The class ensures that initialization is done in the correct order.

    • luaMain

      public static Varargs luaMain(LuaValue mainChunk, String[] args)
      Simple wrapper for invoking a lua function with command line arguments. The supplied function is first given a new Globals object as its environment then the program is run with arguments.
      Returns:
      Varargs containing any values returned by mainChunk.
