Hello,  
I am using the below given code to parse ruby code line by line and  
generate its s-expression (AST). The help i need from you is that i want  
to parse the whole ruby file at a time instead of parsing line by line.

require “ruby\_parser”

# puts RubyParser.new.parse(“My name is defecto”)

counter = 1  
file = File.new(“readfile.rb”, “r”)

while (line = file.gets)  
puts “#{counter}: #{RubyParser.new.parse(line)}”  
counter = counter + 1  
end
