            Arrow lens won't let me set a nullable property to null
            Asked 2020-Dec-10 at 13:41

            Given this (extremely simplified) code :

            ANSWER

            Answered 2020-Dec-10 at 13:41

            The @Optics compiler generates 2 optics for that property.

            MigrationStatus.token & MigrationStatus.tokenNullable or MigrationStatus.tokenOption in the case of Option.

            This is because there are two different Optics that are useful here.

            • Lens which has set & get and in this case `Lens
            • Optional which has set & getOption and in this case `Optional

            The first one is the one you'd want to use in this case to be able to set String? to null.

            So MigrationStatus.tokenNullable.set(null).

            The latter is more useful for the DSL, and composition of Optics since if instead of String? you had another data class or sealed class you'd want to operate on the value only in the case of not-null.

            I hope that fully answers your question!

            ArrowKt Try alternative for eager execution
            Asked 2020-Jan-30 at 01:24

            ArrowKt has deprecated Try since it promotes eager execution of effects and it recommends to use suspend constructors. But how should I handle following case where I do want eager execution on purpose without using traditional try-catch.

            There is no need for any special construct beside try/catch in Kotlin, since it's also already an expression. For that reason it was removed from Arrow, you can simply write:

            Transforming a Spring Webflux Mono to an Either, preferably without blocking?
            Asked 2019-Mar-03 at 14:16

            I'm using Kotlin and Arrow and the WebClient from spring-webflux. What I'd like to do is to transform a Mono instance to an Either.

            The Either instance is created by calling Either.right(..) when the response of the WebClient is successful or Either.left(..) when WebClient returns an error.

            What I'm looking for is a method in Mono similar to Either.fold(..) where I can map over the successful and erroneous result and return a different type than a Mono. Something like this (pseudo-code which doesn't work):

            Answered 2018-Apr-24 at 12:07

            I'm not really familiar with that Arrow library nor the typical use case for it, so I'll use Java snippets to make my point here.

            First I'd like first to point that this type seems to be blocking and not lazy (unlike Mono). Translating a Mono to that type means that you'll make your code blocking and that you shouldn't do that, for example, in the middle of a Controller handler or you will block your whole server.

            This is more or less the equivalent of this:

            Yes, you can use Arrow Datatypes in Groovy, the result is not as idiomatic as in Kotlin because the library heavily depends on extension functions and functions in the companion object

            Custom spring-kafka deserializer for LocalDateTime
            Asked 2018-Dec-07 at 09:07

            I'm building a simple project with spring boot and spring-kafka, I can't configure it in order to make it work, it's a simple application that generates notes(author, content, createddatetime, lastmodifieddatetime) and sends events based on the notes when they are created.

            I have been playing with it with 2 days but I guess I'm not getting it.

            Here is my configuration, I'm pretty sure it has a lot of boiler plate but I've been using several examples to make mine work.

            I have 2 producer and consumer factories because I need a default one, is that true? Do I need to create a custom factory for each type of message I am willing to send?
