Tim Bray. What a newb. But for being a Ruby nuby, he’s already posting hacks like he’s got recalescent digits. This JRuby stuff he’s got up right now makes me whinny!

 # Rename Java's Data class as JDate in Ruby
 include_class('java.util.Date') {|p,n| "J" + n }

 # Use Java's RSS/XML libs to fill a Ruby array
 ARGV.each do |arg| 
   feed = SyndFeedInput.new.build(XmlReader.new(URL.new(arg)))

   feed.entries.each do |entry|
     entry.setTitle "#{feed.getTitle}: #{entry.getTitle}" 

     aEntries << entry
   end
 end

 # Sort the entries in Ruby
 aEntries = aEntries.select { |e| e.getPublishedDate.between?(earlier, now) }
 aEntries.sort! { |a, b| b.getPublishedDate <=> a.getPublishedDate }
 aFeed.setEntries aEntries

Get the picture? The script of note is here. (The original agog struck on Tim’s blog.)
