What is the best way to define log TAG constant in Kotlin?

Question

I\'m creating my first Kotlin classes in my Android application. Usually for logging purposes I have a constant with name TAG. What I would do in Java is:

I found a way which is more "copy-paste"-able, since it doesn't require you to type the name of your class:

package com.stackoverflow.mypackage

class MyClass
{
    companion object {
        val TAG = this::class.toString().split(".").last().dropLast(10)
    }
}

It's not the most elegant solution but it works.

this::class.toString().split(".").last() will give you "com.stackoverflow.mypackage.MyClass$Companion" so you need the dropLast(10) to remove $Companion.

Alternatively you can do this:

package com.stackoverflow.mypackage

class MyClass
{
    val TAG = this::class.simpleName
}

But then the TAG member variable is no longer "static" and doesn't follow the recommended naming conventions.
