  EXPERIMENTAL

  EXPERIMENTAL

  The base package for Scala macros.

  Macros are functions that are called by the compiler during compilation. Within these functions the programmer has access to compiler APIs. For example, it is possible to generate, analyze and typecheck code.

  See the Macros Guide on how to get started with Scala macros.

  EXPERIMENTAL

  EXPERIMENTAL

  The refinement of scala.reflect.api.Universe for the use by macro writers.

  This universe provides mutability for reflection artifacts (e.g. macros can change types of compiler trees, add annotation to symbols representing definitions, etc) and exposes some internal compiler functionality such as `Symbol.deSkolemize` or `Tree.attachments`.

2.  abstract def source: SourceFile

   Source file corresponding to this compilation unit.

   Source file corresponding to this compilation unit.

   Exposes information about the file as a part of a real or virtual file system along with the contents of that file.

   The return type is `scala.reflect.io.AbstractFile`, which belongs to an experimental part of Scala reflection. It should not be used unless you know what you are doing. In subsequent releases, this API will be refined and exposed as a part of scala.reflect.api.
