I have a quoasiquote matcher where q"someMethod[$ts]()" where def someMethod[I <: shapeless.HList]()".
Printing ts gives:
List(shapeless.HNil)
or, e.g.
List(String, Int)
Then I try to assign:
val types: List[scala.reflect.api.Types.Type] = ts
that causes compiler error:
[error] type mismatch;
[error] found : List[_125.u.Tree] where val _125: scala.reflect.api.QuasiquoteCompat.TypeAppliedExtractor{val u: OpTreeContext.this.c.universe.type}
[error] required: List[Context.this.c.universe.Type]
How to compose List[scala.reflect.api.Types.Type] from ts?
As your error message states, ts is a list of trees. More specifically, these will be type trees, and you can extract their types with the tpe method:
val types: List[scala.reflect.api.Types#Type] = ts.map(_.tpe)
Note that I'm using a type projection, since Types is neither a package nor an object, so Types.Type won't work.
