How to use
CodeRef Example
import com.foursquare.macros.CodeRef
import com.foursquare.macros.CodeRef._
// Explicit call. here now contains the
// current file (path relative to compiler wd)
// and line number
val here: CodeRef = CODEREF
// Implicit reference to caller. Gives you the
// line from which the method was called without
// taking a stack trace.
def foo(bar: Int)(implicit caller: CodeRef) {
println("called foo(" + bar + ") at " + caller)
}
foo(1)StackElement Example
import com.foursquare.macros.StackElement
import com.foursquare.macros.StackElement._
// Explicit call. here now contains the
// standard StackTraceElement (implicit from StackElement -> StackTraceElement)
scala> val here: StackTraceElement = STACKELEMENT
// Implicit reference to caller. Gives you the
// StackTraceElement from which the method was called without
// taking a stack trace.
def foo(bar: Int)(implicit caller: StackElement) {
println("called foo(" + bar + ") at " + caller)
}
