Does anyone know how to call an extension function that is also an instance of a type? For example: ...

# kotlin-native

Does anyone know how to call an extension function that is also an instance of a type? For example:

fun test() {
    val bar = Bar()
    val foo = Foo()
    bar.doSomething() // How do you call this function
}

class Foo {
    fun Bar.doSomething() {
        // ...
    }
}

class Bar {
    // ...
}

foo.apply {
    bar.doSomething() // How do you call this function
  }

I see! So the trick is that you have to be encapsulated within the instance?

[mbonnin]

I guess so, not sure 😅

Maybe you'd be interested in context receiver stoo

[mbonnin]

Note it doesn't have anything to do with #kotlin-native

[mbonnin]

Maybe more #general-advice next time

Maybe you'd be interested in context receivers too

I've read up a bit on them, but more couldn't hurt. Thanks!

Ahh I didn't know which channel fit the best. I will be joining that one for sure

Appreciate it

foo.apply typically domes with the implication that you’re modifying foo. If you just need foo as a context, with(foo) is more clear.

Good point thanks for the addition
