Idiomatic way of logging in Kotlin

Question

Kotlin doesn\'t have the same notion of static fields as used in Java. In Java, the generally accepted way of doing logging is:

public class Foo {
    privat         


        

Answer 1

Have a look at the kotlin-logging library.
It allows logging like that:

private val logger = KotlinLogging.logger {}

class Foo {
  logger.info{"wohoooo $wohoooo"}
}

Or like that:

class FooWithLogging {
  companion object: KLogging()
  fun bar() {
    logger.info{"wohoooo $wohoooo"}
  }
}

I also wrote a blog post comparing it to AnkoLogger: Logging in Kotlin & Android: AnkoLogger vs kotlin-logging

Disclaimer: I am the maintainer of that library.

Edit: kotlin-logging now has multiplatform support: https://github.com/MicroUtils/kotlin-logging/wiki/Multiplatform-support
