Hi, I have a question about the latest release. Can I use a variable inside the coroutineExecutorFactory to change logic inside the executor under some conditions? In the 3.x version it's ok because the ExecutorImpl is a class. Now in the 4.x version dsl I'm not sure.

[Arkadii Ivanov]

Yes, absolutely. The lambda is called once per each instance of the executor. You can treat it as an init block. Keep in mind that similarly to the classic class-based Executors, new instances of the Executor can be created for the same instance of Store. This happens when e.g. you trigger a pre-recorded event using the time travel debugger. So in such cases, that block will be called as well.

But in usual production flow - only once per instance of the store.

Thank you. Another question: in the old style it's easy to reuse logic by separating the big intent handler function into smaller functions. In the 4.x dsl style it's boilerplate because I need to write the reused function as an extension function of CoroutineExecutorScope. Can you give me some suggestions?

I need CoroutineExecutorScope because of publish and dispatch

[Arkadii Ivanov]

True! That's why the new DSL is primarily recommended for simple/small stores. But you can check the sample: https://github.com/arkivanov/MVIKotlin/blob/master/sample/coroutines/shared/src/commonMain/kotlin/com/arkivanov/mvikotlin/sample/coroutines/shared/details/store/DetailsStore.kt

Sorry but I can not find the ExecutorScope

[Arkadii Ivanov]

You have to define it: https://github.com/arkivanov/MVIKotlin/blob/196d630778e7629abef242f872f38a7942927ba8/sample/coroutines/shared/src/commonMain/kotlin/com/arkivanov/mvikotlin/sample/coroutines/shared/details/store/DetailsStore.kt#L41

Thank you. Got it!!
