Keep insisting - Arrow Meta

  • KotlinConf, Copenhagen
  • December 06, 2019

Arrow Meta is a library that empowers library and application authors with the ability to write plugins for the Kotlin compiler. Compiler plugins have access to all compiler phases and can intercept and modify the AST, descriptors, and IR intermediate lang for bytecode generation.

Arrow Fx & Arrow Meta - Functional Programming for the masses

  • Functional JVM Meetup, Prague
  • November 27, 2019

In this meetup we discuss the new features of Arrow Fx to write “effectful” programs with an emphasis on simple and declarative programming for everyone. Additionally, we see how Arrow Meta works and how we can use it to improve the ergonomics of Functional Programming in Kotlin.

Kotlin and Arrow: the functional way

  • xConf, Barcelona, Spain
  • August 08, 2019

Kotlin is a great language for developing server-side applications; it’s an object-oriented language and also a functional one, supporting features such as function types, lambdas or higher order functions. But…is this enough to switch completely from an imperative paradigm to a functional paradigm?

In this talk by Noe Luaces, we’ll see how features from Arrow library completes Kotlin in order to follow a pure functional way.

ArrowFx: Functional Programming for the masses

  • Kotliners, Budapest
  • June 07, 2019

In this talk we recap about the imminent future of Functional Programming in Kotlin. With ArrowFx you are able to encode “effectful” programs in a controlled way following the FP principles through a direct syntax. You’ll think you’re writing imperative code!

Higher Kinded Types in a Lower Kinded Language by Jacob Bass

  • Yow! Lambda Jam, Sydney, Australia
  • June 22, 2018

It’s hard coming back down to the earth of a JVM based language after spending time with Haskell and OCaml. This talk will discuss functional programming in Kotlin with the Arrow library, how the abstractions it provides can improve your code, and how this magic that provides higher-kinded types works under the hood.

Introduction to Kotlin Arrow by Jacob Bass

  • Kotlin Meetup, Sydney
  • March 26, 2018

@bassjacob goes through how Funktionale and Kategory merged into Arrow, consolidating two of the most popular FP libraries in the Kotlin space into one powerhouse. The talk is an introduction to some FP concepts, how the libraries work, what features they bring to the table and where you might use them in your code.

It's all about morphisms

  • Voxxed Days, Vienna
  • March 21, 2018

@uberto gives a gentle introduction to Category Theory for programmers used to OOP but interested in Functional Programming. No Haskell knowledge required. We will explain main concepts behind functional programming with many diagrams and simple metaphors and examples. Some code will clarify how to translate these ideas in programs.
