    Λrrow - Functional companion to Kotlin's Standard Library (by arrow-kt)

    Project mention: Kotlin for JavaScript | news.ycombinator.com | 2022-03-26

    This is very exciting, I have wanted to try Kotlin for quite some time and one of the biggest reasons has been few libraries such as arrow-kt[1].

    > Kotlin/JS provides the ability to transpile your Kotlin code, the Kotlin standard library, and any compatible dependencies to JavaScript.

    What does it means "compatible dependencies"?

  • cats-effect

    The pure asynchronous runtime for Scala

    Scala. With the functional effect systems, like Cats Effect or ZIO, you get superpowers.

    Not only can write programs that are "async", but you also get easy retries (and other tricks), safe refactorability (because of its Pure FP nature), reliable and painless resource management and some other goodies like STM (Software transactional memory).

    It's really that good.

    Project mention: Typeclasses in Python | dev.to | 2021-07-08

    Today I am going to introduce a new concept for Python developers: typeclasses. It is a concept behind our new dry-python library called classes.

  • cats-mtl

    cats transformer type classes.

    Project mention: Gathering dependency management approaches | reddit.com/r/scala | 2022-02-21

    the advanced alternative to the reader monad is to use cats-mtl so you're just asking for capabilities of your effect, like Ask[F, GlobalConfig]

    So composition is tricky in a concrete implementation. https://github.com/kvwatkins/Kinds/blob/main/Kinds.Optics.Concrete/Concrete.fs is a demonstration of concrete composition for optics (in fhsharp) you’ll notice the weird affineish optic in there that you don’t normally see that’s what will allow mixed concrete optics to compose cleanly in a language that has generic parameters and doesn’t support type classes.
