In a few weeks, our team will travel to London to attend Scala eXchange 2017. We’re really excited about it, because we’ll be introducing so-called optic algebras in a lightning talk. Optic algebras emerge to overcome existing limitations on the … Continue reading →

Once we’ve seen concrete optics and profunctors, it’s time to introduce the last installment of this series: Profunctor Optics. Here, we’ll see how to encode optics in a profunctor representation, which takes composability to the next level. As usual, your … Continue reading →

As promised, here it is the second installment of our series on profunctor optics: Profunctors as Generalized Functions. Today, we’ll introduce several members of the profunctor family (Cartesian, Monoidal, etc.) and we’ll provide their corresponding diagrams, to make them more … Continue reading →

Today we start a new series of posts on Profunctor Optics. Since WordPress has some limitations to highlight Haskell snippets, we’ve decided to publish it as a Github repo. You can find the first part here: Optics, Concretely. We hope … Continue reading →

According to Wikipedia, “an Algebraic Structure is a set with one or more finitary operations defined on it that satisfies a list of axioms”. From a programming perspective, that sounds like a bunch of methods defined on a type. In … Continue reading →

As promised, here is our “Hello, World!” example (also in PDF). This kind of program is illustrative to show the very basics of a programming language. Usually, the program consists on showing the string “Hello World!” message in a console. … Continue reading →
