Is there a cleaner way to pass in an empty trailing lambda besides this?

val example = funWithLambdaParam(arg1) {} // This just looks ugly to me

I was hoping I could just pass in something like ::Unit but that doesn't seem to be a feature

[Larry Garfield]

I think funWithLambda(arg1, {}) should still work just as well, no?

[Joshua Hansen]

That's arguably worse because now I have a squiggly line under it since intellij wants me to move the lambda outside the parentheses

[Larry Garfield]

Silly IntelliJ…

if funWithLambda is your own function, you could simply add {} as the default value of your parameter, like fun funWithLambda(arg1: Int, f: () -> Unit = {}) { ... }

otherwise you could define a constant somewhere like val noOp = {} and pass that to funWithLambda instead, but it would only work for lambda's without parameters of course

[Joshua Hansen]

To my brain, I feel like ::Unit would be a nice way to represent "a function which takes no parameters and returns Unit" but it's just syntax sugar blob shrug If this wasn't kotlin with all of its bells and whistles, to be fair, I wouldn't be complaining

[Wout Werkman]

If that's your opinion, nothing stops you from defining the function:

fun Unit(): Unit = Unit

[Larry Garfield]

I feel a Yo Dawg meme is appropriate here.

When I type the lambda {} IntelliJ warns me that it is an unused parameter and suggests to change it to { _ -> } 🤮

[Joshua Hansen]

I guess this will do

val example = funWithLambda(arg1, fun() = Unit)

[Joshua Hansen]

It is objectively more fun
