Kategory VS SDKMan

Yeah, it has nice funcional capabilities and libraries (like Arrow[0]).

Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.

Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.

In my own code, I started to use explicit error handling. I'm currently experimenting with Result (from https://github.com/michaelbull/kotlin-result) and Raise (from https://arrow-kt.io/).

Are there any more-or-less established functional crates in Rust (similar to Kotlin’s Arrow)?

I wonder how the community sees adding Arrow besides standard Kotlin language features. Is it something that's still considered useful or just redundant and causing more confusion?

You can define a function like context(EitherEffect) suspend fun MyType.bind(path: String)like the ones in https://github.com/arrow-kt/arrow/blob/b608a054a5318fe57d7055c35bb64a5effb053b6/arrow-libs/core/arrow-core/src/commonMain/kotlin/arrow/core/computations/either.kt

If you're using Kotlin, I'd highly recommend looking into the https://arrow-kt.io library. It's quite a bit more sophisticated than the Dart FP libs, and meshes well with Kotlin. They've got a great website, but even better is their engagement on the #arrow channel on the kotlinlang.slack.com Slack.

Alternatively, you can use sdkman. A great tool to install your Software Development Kit. The downside is that it only works on *nix systems. So for Widnows users, you will have to use WSL or Cygwin as the official page suggests. It is really simple to use sdkman. after a successful installation, just type those commands into your *nix shell:

To run the example, you must install the Auth0 CLI and create an Auth0 account. If you don't have an Auth0 account, sign up for free. I recommend using SDKMAN! to install Java 17+ and HTTPie for making HTTP requests.

Another option for installing Java is SDKMAN!, a versatile tool that’s easy to install and helps you manage multiple versions of Java.

Java 17

Java 17 or higher. You can use SDKMAN! to install Java if you don't have it already.

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

If you have any tips/advice then I'm all ears. I've already modified the dnf.conf with fastmirror and max_parallel_downloads I'm currently not using sdkman because this is my personal machine, so I don't mind always using the latest version OpenJDK. If I ever do need to switch between versions then I'll switch over to sdkman instead.

For handling your JDK: I highly recommend purging your system of all JDKs/JRMs - get rid of it all - and download SDK (if you're using Windows, you'll need to do this through WSL). This tool manages software development kits very well; switching between JDKs is super straightforward: sdk use .

I use sdkman to install java related stuff. Check it out. No root needed.
