Use Kotlin string templates or string formatting arguments?

[erikhuizinga]

Kotlin has string templates, e.g. "Hello, $person!" where person can be some string. I wonder: how does such a string with template perform when passed to Timber, compared to a string formatted with arguments like so: Timber.v("Hello, %s!", person)? Is there a noticeable/significant difference between the two?

Therefore, should Timber's lint rules warn about string template usage?
Or on the contrary, should strings with formatting arguments in Kotlin files result in a warning that they can or should be replaced with templates?

Another thing to consider is a mention in the Timber docs about this: which of the two methods is preferable?

Kotlin string templates are an idiomatic language feature and may therefore be preferable. I'm unaware of the underlying compile-time/runtime details of string templates, which may be different per Kotlin platform.

This is related to a few other issues where Timber-Kotlin interop is discussed.

This being Kotlin, the preferred way would be:

Timber.v { "Hello, $person!" }

And don't evaluate the lambda when verbose is not loggable.
