I think I have found a hack. Check this out:

require 'gtk2'
Gtk.init
window = Gtk::Window.new
window.signal_connect("destroy") { Gtk.main_quit }
textviewer = Gtk::TextView.new
window.add(textviewer)
window.set_default_size(600,400)
window.show_all
buffer = textviewer.buffer
buffer.create_tag("blue", {"foreground" => "blue"})
buffer.signal_connect('insert-text') do |a,iter,text,length|
  offs = iter.offset
  Gtk.timeout_add(10){
    iter = buffer.get_iter_at_offset(offs)
    iter.forward_to_line_end
    limit_iter = buffer.get_iter_at_offset(iter.offset)
    iter.line_offset = 0
    if a = iter.forward_search('#', Gtk::TextIter::SEARCH_TEXT_ONLY,
limit_iter) or text == '#'
      iter, = a if a
      2.times{
        buffer.apply_tag(buffer.tag_table.lookup("blue"), iter, limit_iter)
      }
    end
    false
  }
end
Gtk.main

Cheers,
