I released a new version of Trollop [1] with a couple minor but cool updates.

The best part is the new @:io@ argument type, which uses @open-uri@ to handle
filenames and URIs on the commandline. So you can do something like this:


require 'trollop'
opts = Trollop::options do
  opt :source, "Source file (or URI) to print",
      :type => :io,
      :required => true
end
opts[:source].each { |l| puts "> #{l.chomp}" }


Also, when trying to detect the terminal size, Trollop now tries to @`stty
size`@ before loading curses. This gives better results when running under
screen (for some reason curses clears the terminal when initializing under
screen).

I've also cleaned up the documentation quite a bit, expanding the examples on
the main page [2], fixing up the RDoc comments, and generating the RDoc
documentation [3] with a modern RDoc, so that things like constants actually
get documented.

If you're still using OptParse, you should really give Trollop a try. I
guarantee you'll write much fewer lines of argument parsing code, and you'll
get all sorts of nifty features like help page terminal size detection.
