Ruby - compile fail , empty error dump

Updated Thursday, July 24th 2014 @ 17:03:05

Hey all i am trying to test a simple bot written in ruby and i cant seem to find what is wrong...

I guess something to do with input and output but cant figure it out.

Here is the sample code for a bot that just checks

class bot
  #....

  def run
    while $stdin.closed? == false
      line = $stdin.gets
      $stderr.puts 'in loop'
      next if line.empty?
      Engine.parse(line)
      if Engine.action?
        $stderr.puts 'action time!'
        check
        $stdout.flush
      end
     end
   end

end

STDERR.puts "it runs"
testbot = Bot.new
testbot.run

i tried with something even simpler and still fails with empty error dump

while $stdin.closed? == false
  line = $stdin.gets
  $stderr.puts 'in loop'
  next if line.empty?
  line = line.split(' ').map {|x| x.downcase}
  if line[0] == 'action'
    $stderr.puts 'action time!'
    $stdout.puts 'check 0'
    $stdout.flush
  end
end

Thanks jim it works fine now.
For anyone wondering: put #!/usr/bin/env ruby at the top of the init file and enclose the running method like this: if FILE == $0 Bot.run end
