akka-macro-logging

Akka Macro Logging adds support for lightweight logging using Scala Macros. It's a thin wrapper around the logging facilities provided by Akka avoiding unnecessary evaluation of log messages or arguments by rewriting unchecked invocations of log messages to their checked form:

// Simply use `debug` or other log methods without checking whether enabled
log.debug("Invalid foos {}", foos.mkString(", "))

// The macros rewrite the above to
if (log.isDebugEnabled) log.debug("Invalid foos {}", foos.mkString(", "))

Getting Akka SSE

Akka SSE is published to Bintray and Maven Central.

// All releases including intermediate ones are published here,
// final ones are also published to Maven Central.
resolvers += Resolver.bintrayRepo("hseeberger", "maven")

Usage – basics

The API uses the same names like the Akka Logging API, i.e. ActorLogging and LoggingAdapter. So all you have to change in your code are the imports:

import de.heikoseeberger.akkamacrologging._

class MyActor(foos: Set[Foo]) extends ActorLogging {
  log.info("Initialized with {}", foos.mkString(", "))
  ...
}
