Json4s.org Website Review

At this moment there are at least 6 json libraries for scala, not counting the ja*a json libraries. All these libraries have a very similar AST. This project aims to provide a single AST to be used by other scala json libraries. At this moment the approach taken to working with the AST has been taken from lift-json and the native package is in fact lift-json but This project also attempts to set lift-json free from the release schedule imposed by the lift framework. The Lift framework carries many dependencies and as such it's typically a blocker for many other scala projects when a new version of scala is released. So the native package in this library is in fact verbatim lift-json in a different package name, this means that your import statements will After that everything works exactly the same as it would with lift-json In addition to the native parser there is also an implementation that uses jackson for parsing to the AST. The jackson module includes most of the jackson-module-scala functionality and the ability to use it with the lift-json AST. Be aware that the default behavior of the jackson integration is to close the stream when it's done. If you want to change that: A central concept in lift-json library is Json AST which models the structure of a JSON docu*ent as a syntax tree. case object JNull extends JValue case clas* JString(s: String) extends JValue case clas* JDouble(num: Double) extends JValue case clas* JDecimal(num: BigDecimal) extends JValue case clas* JInt(num: BigInt) extends JValue case clas* JBool(value: Boolean) extends JValue All features are implemented in terms of above AST. Functions are used to transform the AST itself, or to transform the AST between different formats. Common transformations are summarized in a following picture. You can add the json4s as a dependency in following ways. Note, replace XX* with correct Json4s version. For the native support add the following dependency to your project description:
