Build Status

Really simple JSON and XML parsing, ripped from Merb and Rails. The XML parser is ripped from Merb and the JSON parser is ripped from Rails. I take no credit, just packaged them for all to enjoy and easily use.


  • ruby 1.8.7
  • ruby 1.9+ (3 failures related to time parsing, would love it if someone could figure them out)

note on patches/pull requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • script/test - this will bootstrap and run the tests
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself in another branch so I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.


gem 'crack' # in Gemfile
require 'crack' # for xml and json
require 'crack/json' # for just json
require 'crack/xml' # for just xml


Crack::XML.parse("<tag>This is the contents</tag>")
# => {'tag' => 'This is the contents'}

Crack::JSON.parse('{"tag":"This is the contents"}')
# => {'tag' => 'This is the contents'}
