Scalahost provides implementations of scalameta/scalameta contexts for compile-time and runtime metaprogramming with scala.meta. The implementations are based on the pre-existing scala.reflect framework and scala.tools.nsc.Global.
This project is still in a pre-alpha stage, so it's not supposed to be immediately usable just yet. Nevertheless, we are regularly publishing snapshot builds to Sonatype, so it is already possible to experiment with scala.meta as described at https://github.com/scalameta/example.
As with any snapshot software, things may crash and burn and APIs may noticeably change overnight, but if you're brave enough, proceed using the instructions, and you may find hidden treasures!

The public API of this project is minimal and consists of a single module: scala.meta.Scalahost, which exposes methods to create a scala.meta.semantic.Context at compile time (from an instance of scala.tools.nsc.Global) and at runtime (from a classpath):
// compile-time context
import scala.meta._
implicit val c = Scalahost.mkGlobalContext(global)// runtime context
import scala.meta._
implicit val c = Scalahost.mkStandaloneContext("-cp ...")To see what can be done with a context, consult the readme at scalameta/scalameta. To see how this can be done, take a look at an example project at scalameta/example.
