hello guys, I am fighting with intellij and coroutines. I try to use

produce

I have imported it from

import kotlinx.coroutines.channels.produce

but the ide still displays it red, and says

create function

on alt-enter. my dependencies are

implementation 'org.jetbrains.kotlin:kotlin-stdlib-jdk8'
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-jdk9:1.3.7'
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-javafx:1.3.7'

is

kotlinx-coroutines-jdk9

a thing? I thought there was only

jdk8

Additionally, you may need an explicit dependency on

kotlinx-coroutines-core

, I don't know if the other ones declare it as

api

or

implementation

, the latter would mean

core

wouldn't appear on your classpath

I will try this

(the jdk9 flavour added interop with Java9's Flow, a reactive streams implementation)

yes, I see that now

did not change

oh, I know why that's unresolved -- you don't have a

CoroutineScope

to call it on

hmm that is it

yes, the scoping / structured concurrency was added in the later iterations of coroutines

then this leads to my next question. the examples on the kotlin site are for functions, but I would like to use produce in a method of a class. how can I get the coroutine scope there

pass it as a normal argument, either to the method or the constructor

thanks for your help! I will try further 🙂 (it is harder to wrap my head around it than I first thought)
