Puppet users - May 2014 - Custom Fact Help? Works in ruby, but not facter...

Hi,

I'm working on custom fact that uses Facter::Util::Resolution.exec to run a 
command that returns output I want to parse with regex.  If I write up a 
ruby shell script like:

#!/usr/bin/ruby

out = `<command>`
out = out.gsub!(/<regex>/, "\\1\\3")
puts "#{out}"

The desired output comes to the screen, every time, and on every system I 
run it.

If I modify the script to be a fact like so:

# custom fact
require 'facter'
Facter.add(:newfact) do
  out = Facter::Util::Resolution.exec("<command>")
  out = out.gsub!(/<regex>/, "\\1\\3")
  secode { out }
end

A puppet run actually prints the full output of the command twice after 
syncing the fact.  Running facter -p newfact does the same.  On top, the 
printed output is the raw output not the regex filtered.

What am I doing wrong here?

Thanks!
