A very basic Ruby example importing the RubyGem and using puts to output to console, using the two methods parse and generate. Source code for compactdata-ruby available on GitHub
require "compactdata"
puts CompactData.parse("foo=bar")
# -> {"foo"=>"bar"}
test_obj = Hash.new
test_obj["foo"] = "bar"
puts CompactData.generate(test_obj)
# -> foo=bar
