Is there something like `@JvmSynthetic` in K/JS?

Is there something like @JvmSynthetic in K/JS?

[Animesh Sahu]

Or something to mark a function to not be with @JsExport ?

[Animesh Sahu]

(sort of?)

[turansky]

internal ?

[Animesh Sahu]

No, not to be internal for Kotlin actually

[turansky]

Do you create this class inside only?

[Animesh Sahu]

Kotlin?

[turansky]

You can use Proxy, If you create instances only inside Kotlin

[Animesh Sahu]

No not that way, I was talking about not exporting some functions from a class.

[Animesh Sahu]

Marking @JvmSyntheic on functions makes it non callable from Java (usecase includes suspending ones)

[turansky]

What about inline or extension methods
They will have such “effect”

[Animesh Sahu]

Extension functions are good, but ... 😅

[Animesh Sahu]

Isn't there something like @JsSynthetic?

[Animesh Sahu]

I was expecting I could make a IR plugin, which can make things like suspend functions hidden from @JsExport and make stubs for it automatically that are interoperable.

[Animesh Sahu]

idk if its viable, but that was the primary goal*

[turansky]

You can mark those methods as private via plugin 🙂

[Animesh Sahu]

That'd make them private from kotlin side as well? No?

[turansky]

No 🙂

[Animesh Sahu]

Tysm!

[Animesh Sahu]

Oh wait no, I mean like, if it is going to be library, it wouldn't seen private, but as public from Kotlin end? 😮

[turansky]

You can do this trick for apps only

[turansky]

AFAIK @JsExport works for current subproject only

[turansky]

And suspend function musn’t be exported

[turansky]

It looks like a bug

[Animesh Sahu]

how about fun abcd(param: suspend () -> Unit) ?

[Animesh Sahu]

That's also not exported?

[Animesh Sahu]

It looks like a bug

Havent matched exactly, but I guess they were, have to recheck.

[turansky]

suspend - Kotlin specific, which must be hidden (and mangled)

[turansky]

Issue required 🙂
