Hey All, I came across a fascinating

video▾

with @raulraja and @simon.vergauwen on youtube: Arrow FX: Functional Domain Modeling with Kotlin. Was wondering a) is there an associated github repo? I’m having a difficult time figuring out things like i.e. required dependencies for the @Refinement annotation, etc… and b) are there more videos like this that show idiomatic Arrow being applied to real-world applications? Thanks!

Hi Ian, The type-system features are in Arrow Meta but won’t be pushed as stable until the compiler plugin API stabilizes in the compiler with the IR backend around 1.5. In the meantime some of those features are available in snapshots in Meta for 1.4.10. As for all the Fx related functionality is part of Arrow Fx and 0.11 already has everything shown there regarding that in 0.11.
The current issue with type system features in meta is that the kotlin IDE plugin still does not cooperate and for that we need proper support for IDE plugins for their side plugins which may come down the road.

Thanks @raulraja!

A book I'd buy w/o reading the table of contents: "Functional Domain Modeling with Kotlin" by Raja & Vergauwen :)
