(Unsafe) cast the map to

Map<Any, V>

Note that that's a strange/hacky thing to do.

well, I am doing this for unit testing a custom map implementation

so hopefully it is alright /shrug

How would I go about debugging an ICE? I don't even know which file, which code, is causing it 😞

Is there something faster than binary searching my code?

I try to migrate to a new kotlin-mavev-plugin and get

Why doesn't this code compile? https://pl.kotl.in/FyZkS9dLC

fun main() {    
    val response = foo<String>(Bar().boot())
}

fun <T> foo(x: Bar<T>) = listOf(x)

class Bar <U> {
    fun boot() = this
}

It seems to me that the compiler should have enough information to infer

U

, as it must be

T

100% of the times

Suppose I have a monostate class/object inheriting from an interface:

interface Dimension {
    val dimension: Int
}

object DimThree : Dimension {
    override val dimension = 3
}

etc Now suppose I have these users of said interface

data class Point<D : Dimension> private constructor(val data: List<Int>) {
    constructor(d: D, init: (Int) -> Int) : this(List(d.dimension, init))
}
operator fun <D : Dimension> Point<D>.plus(p: Point<D>) = Point(<need an instance of D>) { this.data[it] + p.data[it] }

As we can see, I need an instance of D there, which should be trivial since D is monostate in practice. The question is, is there any way to define my interface Dimension, so that if I have a

D: Dimension

, I can obtain an instance of

D

? The only solution I have found here so far, not very nice is to have each Point store a D; this is a waste of space since a Point<D> already knows this information

I can make things inline/reified if that helps

Any way to inspect primitive constant values from idea/klib utility in a klib? It currently says compiled code, but primitive types should be easily accessible, aren't they?

On a related note, I didn't realize until now that getOrPut is an extension convenience function, I thought it was a member that was saving you hashing twice, but I suppose this isn't changeable since it's backed by Java hash maps

how ktor handle redirect response? I want to read a header from an address, and that address return a redirect addr, and ktor throw an exception, how to fix that? https://paste.ubuntu.com/p/GnFvcbCyMD/

for example, instead of

fun overload(message: String)

fun overload(message: ByteArray)

similarly to TypeScript's implementation of such.

Like now it just happened, and I enter my preferred codestyle and copy it to current project codestyle. But when I then hit auto format it seems to apply the default code style. And that is extremely annoying.

Can I even delete the official code style?
