https://twitter.com/kotlin/status/1085890317147168768 Google’s new client library for Actions on Google is a great example of a library built entirely in Kotlin and intended to be used from both Java and Kotlin clients. https://t.co/Grzg7Q1kpx Twitter

How to specify and concatenate groups of bits with unknown lengths? E.g I've a class with a value that I'd like to represent using 4 bits and another 2 bits, and I'd like to concatenate these in a 6 bit array. It's probably something along the lines of shifting and using bitwise OR operator. But maybe there's a better way?

Related: Is there something out of the box to get the bits (e.g. as a

BitSet

) from a numeric type (e.g. a

Byte

)? Edit: The answer to this question is

BitSet.valueOf(bytes)

Is this the channel I should use to help with intellij/gradle/kotlin?

Getting a "The feature "function reference with default value as other type" is disabled" that is pretty explicit but the quick fix is to use languageVersion = "1.3" and it's already the case, is this an 1.4 feature with a quick fix error or there's another flag that I can't find ?

How do I make this compile?

Copy code

sealed class InputSelection<T> {
    object None: InputSelection<T>()
    data class Some<T>(val value: T): InputSelection<T>()
}

I tried with

Copy code

sealed class InputSelection<T> {
    object None: InputSelection<Nothing>()
    data class Some<T>(val value: T): InputSelection<T>()
}

but then I can't use

InputSelection.None

where I'm expecting an

InputSelection<T>

iex

05/09/2020, 6:39 PM

ah, I have to use

out T

in the type declaration. and

Nothing

in the

None

type

With

StateFlow

out which is yet another construct that requires separate private and public type (

MutableStateFlow

and

StateFlow

), what is the status of https://github.com/Kotlin/KEEP/pull/122?

I think your 0xffff_0000_0000_0000 is out of range?

has anybody already implemented gradle 6.4 with kotlin and JPMS here?

iex

05/11/2020, 1:24 PM

is there a shorthand for this?

Array(15) { false }.toList()

(generates a list with 15

false

elements)

List(15) { false }

I dont fancy early returns either

spand

05/12/2020, 7:31 AM

But if you are using early returns then I would agree with elizarov

christophsturm

05/12/2020, 8:18 AM

i think very early returns are ok and easy to read and understand

https://twitter.com/kotlin/status/1260140196265439232 To battle-test your new API ideas, mark new classes and functions as "experimental" by using the @⁠⁠OptIn annotation. This way, everyone can try it, but they have to explicitly acknowledge that they understand this API is subject to change. #KotlinTips https://t.co/KLhdqy3hbz https://t.co/ITsnoyApwj Twitter

Anyone can give feedback utilizing a vscode extension for Kotlin. Any post, docs, video to share for setting up will be appreciated.

I'm getting this error when I try to compile some code with new IR backend with 1.4-M1 (Kotlin/JS).

Copy code

e: java.lang.IllegalStateException: IrSimpleFunctionPublicSymbolImpl for public pl.treksoft.jquery/JQuery.get|2639228273376077075[0] is already bound

Should I fill an issue? Or it's just too early to use it?
