oh...and, is

block

even a valid argument to itself?

maybe no 🙂

block

takes a

() -> T

but

block

itself is a

(() -> T) -> T

yes, my example is broken

@kirillrakhman are the best. vote for him

@miha-x64 I've played around with it and I don't think this is possible only with function types, because the declaration would have to be recursive.

Yes, I think there’s no way too 🙂

Hi! Are there any tools that are capable of generating UML schemas from kotlin classes?

I tried using a built in one in intellij but it seems to fail to resolve superclasses

To all the new Spanish speakers, there is #spanish channel if you want to join

Hi everyone!

Hello, I think Kotlin is also great when I want to write not so much code (compared to Java). I would love to have a syntax for "extending the primary constructor of the superclass", because I write a lot of classes like this:

@User uploaded a file: Untitled

Is there something known for making this easier? Or is Kotlin more directed on staying explicit in cases like this?

you may write

override val ...

in the primary constructor if the property is abstract

No, that does not really solve the problem, I guess.

@User uploaded a file: This does not work

At class B decleration I still have to invoke the constructor of A (of course).

I’m afraid there is no luck here, you have to be explicit in the method signatures.

Oh ok. I was hoping to have something similar to a varargs type, a constargs type maybe 🙂

@User uploaded a file: Untitled

of course this is not as easy as my example because of possible secondary constructors of A .... but it would be a great feature! 🙂

.. at least for me 😕

I’ve wanted something like that recently. Something like “This has the same constructors as its superclass but requires this additional parameter”, I don’t know of a good way to generalize the problem though (ie. maybe it’s +2 parameters -1 parameter because you’re using a constant somewhere).

The -1 is a brain twister. Probably the resulting syntax will be non-straightforward for normal programmers. We don't want to create another Scala here 😉

The only general thing I can think of might be some extension of delegation, but it’d probably still be classified as “code I do not want to see in the wild"

yeah that's true. me neither.
