Pretty print json from irb

.irbrc

def ppjson(json)
  puts _ppjson(json)
end

def _ppjson(json)
  json = JSON.parse(json) if json.class == "String"
  JSON.pretty_generate(json)
end

class String
  require 'json'
  def ppjson
    puts _ppjson(self)
  end
end

class Hash
  def ppjson
    puts _ppjson self
  end
end

Thanks for sharing this! Such a great idea. I think line 6 needs to be if json.class == String
