Examples of org.jruby.compiler.ir.IRScope

org.jruby.compiler.ir.IRScope
IRScope is the interface for all lexically scoped constructs: Script, Module, Class, Method, and Closure. It is important to understand that a single class (e.g. MyFoo) may be opened lexically in several locations in source code. Each one of these locations will have their own instance of an IRScope.


public class Interpreter {
    private static boolean debug = Boolean.parseBoolean(System.getProperty("jruby.ir.debug", "false"));
    
    public static IRubyObject interpret(Ruby runtime, Node rootNode, IRubyObject self) {
        IRScope scope = new IRBuilder().buildRoot((RootNode) rootNode);
        scope.prepareForInterpretation();
//        scope.runCompilerPass(new CallSplitter());


        return interpretTop(runtime, scope, self);
    }
