Is there a kotlin function to scope an object on a condition? Something like withIf(myObject.propertyToFiler == true) { myObject -> ... }

A function with this signature would be impossible, as you just pass a boolean to it.

You could use:

if (myObject.propertyToFiler == true) with(myObject) { myObject -> ... }

[molikuner]

Or if you need a function:

inline fun <T, R : Any> withIf(x: T, access: Boolean, block: (T) -> R) = if (access) with(x, block) else null

There are stdlib functions takeIf and takeUnless.

Ah, takeIf is that I thought I’d seen before

But molikuner’s function is actually a nicer solution
