This page is a top level directory of all Lua content at this wiki, grouped by topic. Coroutines are very simple in their nature, but take a while to understand, as it's hard to think of something that is both sequential and synchronous in a way, while working asynchronously. So over in r/webdev they have a showcase thread every week which got me wondering if we could have something like that too. Kotlin Runs Taxes in Norway. The syntax of coroutines makes more sense to me and now with ROOM adding additional support in that direction it makes my switch to just coroutines even better. UI code calling into service layer (what’s the abstraction there), service layer calling into a networking library (Retrofit), JSON getting parsed into model (on BG thread) and model/results propagating up to the presentation layer for subsequent hydration.

So over in r/webdev they have a showcase thread every week which got me wondering if we could have something like that too. Coroutines can run in parallel or concurrently, wait for other coroutines and communicate with each other. Coroutines are very lightweight threads that do not correspond to underlying kernel threads, so that when a coroutine needs to "block" it gets suspended and frees its current kernel thread so that another coroutine can process events. So, a good tool support or testing in a simulated environment is recommended. Kotlin/Native Beta.

I think Kotlin's coroutines are an impressive piece of engineering but if there's something I regret it's that it encourages to write code in an imperative style. Kotlin coroutines are much more than just lightweight threads — they are a new paradigm that helps developers to deal with concurrency in a structured and idiomatic way. This is strongly discouraged and is against the coroutines concept. The asyncio package has been included in the standard library on a provisional basis. This makes it possible to use RxJava Observables and Flowables here. Coroutines interact according to the following rules: One coroutine in the set has control, which it retains until it either exits or resumes another coroutine.

Design patterns for the Go programming language (golang), including object-oriented, functional, and concurrent programming patterns. A coroutine is a generalization of a function that in addition to usual control flow operations such as call and return, can suspend execution of itself and yield control back to the caller with an ability to resume execution at a later time. Usually, when using Retrofit 2, we have two callback listeners: onResponse and onFailure If onResponse is called, it doesn't always mean that we get the success condition.
