Macro Example in scala-2.10.0-20120419

MacroSample.scala

import language.experimental.macros
import scala.reflect.makro.Context

object MacroSample {

  def compiledTime(): String = macro compiledTime_impl
  
  def compiledTime_impl(c: Context)(): c.Expr[String] = {
    import c.mirror._
    import c.reify
    val date = Expr(Literal(Constant(new java.util.Date().toString)))
    reify("Compiled Time: " + date.eval)
  }
 
}

2.10 M3で動くように修正してみた。
