Scala Quasiquotes

Examples

Create a syntax tree with quasiquotes

Use quasiquotes to create a Tree in a macro.

object macro {
 def addCreationDate(): java.util.Date = macro impl.addCreationDate
}
object impl {
 def addCreationDate(c: Context)(): c.Expr[java.util.Date] = {
 import c.universe._
 val date = q"new java.util.Date()" // this is the quasiquote
 c.Expr[java.util.Date](date)
 }
}

It can be arbitrarily complex but it will be validated for correct scala syntax.
