TASTy Inspection

Edit this page on GitHub

TASTy files contain the full typed tree of a class including source positions and documentation. This is ideal for tools that analyze or extract semantic information of the code. To avoid the hassle of working directly with the TASTy file we provide the TastyConsumer which loads the contents and exposes it through the TASTy reflect API.

Inspecting TASTy files

To inspect the TASTy Reflect trees of a TASTy file a consumer can be defined in the following way.

class Consumer extends TastyConsumer {
  final def apply(reflect: Reflection)(root: reflect.Tree): Unit = {
    import reflect._
    // Do something with the tree

Then the consumer can be instantiated with the following code to get the tree of the class foo.Bar for a foo in the classpath.

object Test {
  def main(args: Array[String]): Unit = {
    ConsumeTasty("", List("foo.Bar"), new Consumer)
