Implemtation of javascript JsonT transformation library. goessner.net/articles/jsont/ Conforms to most of the JsonT spec minus the javascript function ability. (Have to use Proc’s instead of javascript function)
sudo gem install jsont
>> JsonT.new({'self' => '<div>{$.test}</div>', 'test' => '<p>{$.x} {$.y}</p>'}).transform('test' => {'x' => 1, 'y' => 2})
<< <div><p>1 2</p></div>
>> JsonT.new({'self' => '<div>{$.test}</div>', 'test' => Proc.new{|t, opts| t['x']+t['y']}}).transform('test' => {'x' => 1, 'y' => 2})
<< <div>3</div>
