Subject: Re: Windows based Parser

Hi Daniel!

Thanks for helping me. I am able to install ParseTree on my windows 
system. Further, it also requirs RubyInline, so I also installed it. But 
I am still unable to run a simple example of parse tree so far.

I read in it documentations that

  def conditional1(arg1)
    if arg1 == 0 then
      return 1
    end
    return 0
  end

becomes:

  [:defn,
    :conditional1,
    [:scope,
     [:block,
      [:args, :arg1],
      [:if,
       [:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
       [:return, [:lit, 1]],
       nil],
      [:return, [:lit, 0]]]]]

But how can I get this output. I am unable to do so. Actually I am 
farely new to Ruby & specially parsing. Further, I have to run this 
parser on Rails but no way yet. I am not able to run a simple example of 
parsetree. I study much material about parsing but donot have a clue 
that how to get the above output of the source file. I will be very 
thankful,if you can guide me with a very simple example how to use 
parsetree to get above output. I am waiting your kind reply.

Bye
