Subject: Regexp and using the matched value returned/found.

Hi

I'm trying to do a regex search and using what I find a key to a Hash to
dig up some formatting info.

But what's happening is the literal \\1 or \\0 (or \1 \0) is not being
resolved to what's being found.

Any help would be awesome.

Ex: (Doesn't work)

   # regex looks like this: @swi_start = /SWI((dm)|(ph)|(ty)|(st))st/
   // executed in my code:
   line.gsub!( swi_start, self.colorize_token( '\\1' ) )
   # also not working: line.gsub!( swi_start, self.colorize_token( '\1'
) )

   def colorize_token( event )
      puts "Event: " << event
      return "<font color=\"#{@@color_list[ event ]}\"></font>"
   end

Output:
Event: \1

Ex: (This worked!!!)

  line.gsub!( swi_start, "#{@red_start}\\1#{@red_end}") then

Output:
<font color="red">dm</font>

Lastly please notes I've tried using " instead of ' in my method call
without any change.
