Does detekt have for body expression functions that return Unit and have no explicit return type specification?

This? https://detekt.dev/docs/rules/potential-bugs/#implicitunitreturntype

[Eugen Martynov]

Kinda, I more about preference to write fun x(): Unit by fun x() {} but this looks like really subjective and no objective reasons

[Brais Gabin]

It looks related to this: https://github.com/detekt/detekt/issues/5692

[Brais Gabin]

They add unit as an exception. I guess that you could adapt that rule to get your desired behaviour.

[Brais Gabin]

It could be a flag on detekt or just a custom rule on your side.

Thanks, we enabled explicit mode and I refactored construction fun x() = z() to fun x() { z() } . Which is not agreed style and my personal preference. While I should do instead fun x(): Unit = z() to provide implicit API and keep original author intention.

[Eugen Martynov]

So I was looking for Detekt rule which in most have some objective thinking behind. And finally, I realised that this is pure subjective style.

I hope it is more clear the context about my original message

[Brais Gabin]

I see. No, there is nothing on detekt to accomplish that. But a custom rule could make the job.

[Brais Gabin]

Ktlint also have a similar rule. But I think that unit is an exception for them.

Thanks again for the discussion! Super valuable to find mine bias and correct it.
