Thank you. I'll vote!

well this is an interesting bug… so if you have the jpa module in a library it creates a synthetic noarg constructor, in gradle if your source calls that constructor it will compile… however intellij cowardly refuses to. More I think about it I’m not sure which one is right… I mean technically neither is wrong, so maybe it’s not a bug… though weird that the constructor can be compiled in isolation but not when it’s part of a larger composite build and only in the IDE does it have problems.

hi guys

Trying to consume an API and getting no data through. I’m getting an error

Phenotype API error. Event # cbvq@9670a4c5, EventCode: 12 [CONTEXT service_id=51 ]

which i presume means that the model object isn’t matching the JSON format. Anyone be more specific?

Hi guys! 🙂 I have batch applications developed in Java using jberet (JSR 352 implementation for wildfly) and I would like to migrate this for a microservice in kotlin and ktor. What are my options? Could you guide me in this migration? Thank you!

I want to write a kotlin annotation class that can be applied to type parameters in java code. I see this note here that says it won't (fully) work https://kotlinlang.org/docs/reference/java-interop.html#annotating-type-parameters, and in the docs for

AnnotationTarget.TYPE_PARAMETER

, it notes "(unsupported yet)". Anyone know the status of that ticket / what issues we can face?

Hey guys, I had a question about converting a list of strings into a Gzipped file that I can write to S3 directly

val lines: MutableList<String> = mutableListOf()
// Read in another stream and write a chunk of lines to the above list

val stringToWrite = lines.join { "" }

Now here is where I need help, should I be using

stringToWrite.byteInputStream()

or

stringToWrite.toByteArrray()

? I know that I have to use a GZipOutputStream somewhere but I needed a bit of help lining up all the pipes so that I can give it to the Amazon S3 client. Any ideas? Thanks

Are kotlin native compiled classes usable by Kotlin java ?

Hello channel! I am quite new to KMM, so I would like to ask a question. I have a project, which has both Android & iOS applications. I would like to create a new project from scratch, which will include some business logic for both Android & iOS Platforms with KMM. Afterwards, I would like to export this project to .jar & .framework files and import them in each of my main Applications in Android & iOS. How is that possible? How may I extract the shared code into those files(.jar, .framework?). I have been searching in documents, and I have not found something that is extremely clear to me. May somebody help me? Thanks in advance channel!! :)

I am having an issue with my brain while using KotlinX. I have a few separate classes in a project that parses json from an outside source. There are a few separate flag fields that are mostly human readable (using strings) but some are the bit shifted int value of the flag and do not have any documentation on what they are named. My question is: How do I write a generic serializer that can take both an

Int

and a

String

and output a generic class? How would I do something that essentially looks like this but actually works? Because this currently does NOT work for me

open class FlagSerDes<T>(
    val decodeFromString: (String) -> T,
    val getEncodeString: (T) -> String
): KSerializer<T> {
    override fun deserialize(decoder: Decoder): T = decodeFromString(decoder.decodeString())

    override fun serialize(encoder: Encoder, value: T) {
        encoder.encodeString(getEncodeString(value))
    }
}

class Flag1(val flags: Int) {
    @Serializer(forClass = Flag1::class)
    companion object: FlagSerDes<Flag1>( { Flag1(it.toInt()) }, { it.flags.toString() }
}


class Flag2(val flags: Int) {
    @serializer(forClass = Flag2::class)
   companion object: FlagSerDes<Flag2>( { Flag2(it.toInt()) }, { it.flags.toString() }
}

oof, i just had to write a kotlin class without a primary constructor for the first time in a while. I forgot how much there was in java-style constructor boilerplate

I'm thinking of using it to learn how to implement language interpreters/compilers (instead of another statically typed language like C, C++, Java, Go, Rust, Scala, OCaml)

My "native" language is Python, but I've been learning/trying out different languages for this project

If anyone knows of any books or article series in this subject using kotlin, that would be great too thanks!

Got to say Kotlin is great, the only other language that I've felt this comfortable from the statically typed world has been OCaml.

I know of https://github.com/nlochschmidt/monkey-kt as an example

And the mal implementation https://github.com/kanaka/mal/tree/master/impls/kotlin

Is there a way to convert a kotlin flow into a similar Java abstraction?

I'd need to have a onEach and map method if possible
