Subject: [ruby-talk:8161] $stderr redirection

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi all,

How would I go about redirecting $stderr in a platform independent fashion? 
Currently I am running ruby -c against a source file within backquotes. The 
problem is that when the syntax check is in error, it seems to display the 
output to stderr. I need to grab that output as the return value from my 
method. Here is an example of what I have, which works just fine for a 
"Syntax OK" response.

class SyntaxInterpreter
 
  def invoke(file)
    `ruby -c #{file}`.chop!
  end
 
end

Any thoughts or suggestions about how to do this would be very welcome. Would 
I be correct in thinking that a IO.pipe() might be the trick, or not? 
Although this solution claims in the pickaxe book to not be platform 
independent :(
