Example of overriding a boson core command in a separate library

my_core.rb

module MyCore
  def self.config
    {:force=>true}
  end

  # My overridden version that also handles arrays of hashes with :url
  def browser(*urls)
    urls.map! {|e| e[:url] } if urls[0].is_a?(Hash) and urls[0].has_key?(:url)
    system('open', *urls)
  end
end
