Great suggestion, thanks! As you advised, I dealt with this by calling popen3 (actually I used popen2e):

puts "<pre>"
puts "Converting #{f}..."
require 'open3'
Open3.popen2e(s) do |i,o,t|
  puts o.read
end
puts "</pre>"

Unfortunately all the output appears at once; it would be nice to get each line of output to appear as it arrives. But one can't have everything...

TextMate::Executor.run() is worth knowing about, but I couldn't get it to work in this case, as it seems to expect a Ruby file. Thanks again, this worked great. m.
