is there a function analogical to let but for empty strings
someString?.let { calculate(it) }
I need someString.doIfNotEmpty { calculate(it) } ?

If I have to do that often, I usually define one like this:

private inline fun String?.doIfNotEmpty(block: (String) -> Unit) {
	this?.takeIf(String::isNotEmpty)?.let { block(it) }
}

Note, I'm treating null as empty here, if your usage is different, you may have to account for that.

?.let(block) 😉
