How do I use the Main dispatcher if my platform isn't Android?

What's your UI framework?

[camdenorrb]

I'm not using a UI

[elizarov]

Then you don't have Main dispatcher.

[elizarov]

(nor need one)

[camdenorrb]

:C

[camdenorrb]

Concurrent modification issues tho

[elizarov]

Don't share mutable state. No issues

[elizarov]

(don't make mistake UI frameworks do)

[camdenorrb]

I'm just adding something to my eventbus

[elizarov]

Isn't your eventbus thread-safe?

[camdenorrb]

Ummmm, not currently lol

[elizarov]

That's a bad event bus

[camdenorrb]

;-;

[elizarov]

Reading this might give you some ideas: http://kotlinlang.org/docs/reference/coroutines/shared-mutable-state-and-concurrency.html

[camdenorrb]

Thank you :3

[camdenorrb]

Unfortunately after giving it a read, I don't think it helped me very much idea wise. The only thing I got that seems useful is Mutex for the situation I have run in. Anything else I can read @elizarov?

[elizarov]

It really depends on what you are trying to achieve

[camdenorrb]

I want to add multithreading/coroutine support to my eventbus

[camdenorrb]

Which at the moment, just seems to be an issue with concurrently adding a value to the list

[elizarov]

You might want to learn more about concurrency, first. "Java Concurrency in Practice" is a good book I can recommend.

[camdenorrb]

Alright

[elizarov]

As for coroutines, the easiest thing (that would not require any sharing of mutable state) is to represent your eventbus as an actor, that is confine all its operations to a single coroutine.

[camdenorrb]

Ooo, alright. I'll read up on actors :3

[dewildte]

@elizarov Do you suggest using actor coroutines as the event bus for a multiplatform application?
