Ironruby core - Mar 2008 - console ShowASTs not working ?

Hi

I tried to view what AST''s was being generated when I executed a very
simple
class with the following command line

rbx -X:ShowASTs test.rb

class HelloWorld
  def initialize
    @msg = "hello world"

  end

  def print
    puts @msg
  end
end

h = HelloWorld.new
h.print

I tried doing that on windows in powershell, cmd and on OSX with mono

I also tried a couple of other command switches but none of them seem to do
anything, is that because it''s not supposed to be working?
the other command options i tried were -X:TabCompletion, -X:DumpASTs and
-X:ShowRules
None of them seem to have any effect, do I submit a bug for this?

Thanks
Ivan

-X:ShowASTs works for me. Linux, Mono 1.2.6, IronRuby r76.

Not so important, but why the AST is shown twice?

Note that local variables do not work today in the console.
As a workaround, use globals instead (eg $x = 42 instead of x = 42).

One is before rewriting, the other is after rewriting.

See Microsoft.Scripting/Ast/Compiler.cs, from line 485:

private static void AnalyzeBlock(CodeBlock block) {
    DumpBlock(block);

    ForestRewriter.Rewrite(block);
    ClosureBinder.Bind(block);
    FlowChecker.Check(block);

    DumpBlock(block);
}
