I'm reading this: https://android.jlelse.eu/inline-noinline-crossinline-what-do-they-mean-b13f48e113c2 what's the behavior when I don't specify any of

inline

,

noinline

,

crossinline

?

Hey. Can I have an extension function that would handle

SomeClass<X>

and

SomeClass<X?>

at once?

anyone else feel like the kotlin css and html wrappers are a bit lack luster

Another one with nullability Let’s assume I have a function

fun doSomething(input: SomeClass<Concrete?>)

. Use case is:

val localInstance: SomeClass<Concrete> = ...
doSomething(localInstance)

Should I naively cast local instance to

localInstance as SomeClass<Concrete?>

to use this method? Assume that I can’t change the method.

One of the big problems with

typealias

is that it doesn't offer any type safety. For example, say I'm packing a 2D coordinate of `Int`s in a

Long

, I don't want the

Long

value to ever be interpreted as a number nor the other way around.

I'm doing some dependency updates on a project, and happened to notice the 1.2.70 artifacts have hit Maven Central. Now we just need the IDE plugins to land. 😃 https://search.maven.org/search?q=g:org.jetbrains.kotlin%20v:1.2.70 https://plugins.jetbrains.com/plugin/6954-kotlin

Hello, another general coroutine question. I have a gap in understanding how they work. I know coroutines are supposed to be used when you have to wait for something, specifically IO, for example database read of http call. What I don’t understand is how do I convert/wrap those blocking database/http calls into async calls? And how it will work internally?

Strangest thing that's missing from the language.

The @JvmField annotation stopped the clash messages in the BaseJVMRestWorker class, but any kotlin class subclassing that one gets the conflicts again

according to @karelpeeters link, looks like kotlin does not recognize accessors for subclasses...

If I could ask you a bit more of your time, can you take a look at this? https://github.com/fcopardo/EasyRest2

Is this a known issue?

fun main(args: Array<String>) {
    val foo = object {
        var foo: Int? = null
    }
    
    foo.foo = 5
    
    println(foo.foo) //Yields Smart cast impossible, because foo.foo is a mutable property ...
}

Does the app created by Kotlin include trove code?

if(obj != null)

is not bad itself Maybe you could show to your team members good examples how to eliminate nullability in particular cases

Java is not evil by itself, if the team is still more comfortable doing java, keep using java and introduce kotlin gradually, for example, at view level, for POJOs... take advantage of the interoperability

Result

is now prohibited for use as a return type by compiler

Am I the only one annoyed by the default

toString()

implementation of `object`s inside a

sealed class

? ^^

is there another way to force a compile error on

when

when it is not exhaustive other than using it as expression (e.g. assign it to a variable)?

I submitted an issue https://youtrack.jetbrains.com/issue/KT-26806

Does Kotlin have a reactive streams implementation (like akka streams for example)?

is there a better way to write this function?

inline fun <reified T : Any> getAs(noinline converter: ((String) -> Any)? = null): T = ...

I do use

when

in my main code. This is just in a test class. I am just surprised the compiler was understanding that

result

must be a

Post

just because

post

is from a cast. Especially is it is possible for my function to return a

PostGeneration.Error

or a

<http://PostGeneration.Post|PostGeneration.Post>

. I'm going to write a test case which should return a

PostGeneration.Error

and see what happens...

not important, but just wondering... why are functions like

isNullOrEmpty()

not just an extension property so that the () are unnecessary? so that they can be overloaded? I usually create extensions for readability

Or is it for the sole purpose of not creating an additional middle-ware List between the 2 calls?

I'm writing a gradle plugin in java, I need to consume an extension that's written in Kotlin. https://github.com/tbroyer/gradle-errorprone-plugin/blob/master/src/main/kotlin/net/ltgt/gradle/errorprone/ErrorProneOptions.kt but this class

ErrorProneOptions.class

doesn't appear to be available to me in java. Why? can I remediate?

Hello Androiders, Need a small help. I want to create my own plugin in android studio which will get json text as input and generate a pojo class. I don't want to use ready made plugins i want to create my own. Any help would be appreciated.

Hey guys. I need to make parallel

flatMap

in Kotlin. How to do that ? For example:

val coll: List<Set<Int>> = ...
coll.flatMap{set -> setOf(set, set + 1)}
