Somewhat related I suspect

Normally I just come here to ask a question or complain about a bug, I wanted to take this occasion to say thank you for the help, kotlin/ktor and all related tech are awesome and developers are doing great with it! Thank you JB!

I have another case actually leaking view reference and I'v changed the annonymous obeject creation into an object class and it's done😁

does anyone know if there is any intellij plugin that generates UML diagram from exiting code?

Yes @Hexa if you have intellij ultimate. Right click on the package element in the project explorer and select show class diagram.

I believe it uses the java generated classes, not exactly the kotlin ones. So if you're working with kotlin native or kotlin/js I think you're out of luck

Hey! Any recommendations on a good HTTP client (mostly for use in server applications sending requests to API:s)? We have used khttp for quite a while, and it is generally quite good, but it does not seemed to be maintained anymore. I tried ktor's http client (with Apache), and it seems very promising but I had some issues with serializing data in POST requests. I am using Unirest right now, but I think there may be better options out there, especially for Kotlin.

OkHttp with Retrofit suits a lot of my RESTful needs. What do you need from it that you're not getting?

@Can Orhan From Unirest? It does not have support for coroutines, which would be nice, now I have to wrap each request in an async block (or

withContext

). I just felt that the interface in both khttp and ktor were nicer to use.

has support for coroutines

Hey guys any way to view bytecode generated by Kotlin other than "Show Kotlin Bytecode" in Android Studio / Intellij? I find that bytecode shown by Intellij is not exactly a bytecode, it contains optcodes that are not specified in JVM specification. Anyone can suggest good source of kotlin bytecode knowledge?

Someone with some Kotlin generic experience: Why am I unable to to do this:

fun <T> T.validateAndParse(json: String) : Any? where T: FromJsonString<*>, T: JsonSchema {
    TODO()
}

val fromJson : FromJsonString<*>? = type.companionObjectInstance as? FromJsonString<*>
if (fromJson is JsonSchema) {
    // The compiler can't find `validateAndParse` even though the type should be a union of FromJsonString<*> & JsonSchema
    fromJson.validateAndParse(context.call.receiveText())
}

Is there a workaround I can use to call

validateAndParse

?

It is not a union type, it is an intersection.

where T: FromJsonString<*>, T: JsonSchema

means

T

has to be both

FromJsonString<*>

and

JsonSchema

.

There are no union types in Kotlin.

i am trying to convert my following sequence code to Functional style. any idea how to do so. sequence code

fun start(code : String)  {
        val config = service.getConfig(code)
        if( config == null ) {
            return
        }
        // do actual biz logic based on config.
    }

functional style

fun start(code : String)  {
        val eitherConfig = service.getConfig(code)
        when(eitherConfig) {
            is Either.Left -> return
        }
        val config = either.b

        // do actual biz logic based on config.
    }

doubt: i am not sure how to break function when Right condition occurs and return it. or continue function with right flow.

maybe fun start(code : String) { val config = service.getConfig(code) ?: return // do actual biz logic based on config. }

thanks @VladimirR return comes with some additional lines of logging & return type creation code.

I think I found a bug in the Kotlin plugin, for android studio at least

I have a class that I needed to override equals on past what

data class

can generate, because of some crap with android

And I'm getting a warning that it doesn't have a hashCode()

but

If you write a custom

equals

you probably also need a custom

hashcode

, right?

And if you if you don't happen to need one right now something might change in the future, and then it's dangerous to only see the

equals

one.

@carkral my problem was probably one that I could have solved by changing some stuff

But basically one of the values of my data class is a Bundle, which doesn't have .equals

And I needed a way to compare the data class, down to data in the bundle. So I made an infix function because I can't do an operator overloaded extension function

Where is the best place to ask a question about converting byte data?
