Among the things that the Cats ecosystem truly lacks are 2-effect typeclasses. The following thread is dedicated to the TF approach based on endo-functors F[_], which dominates in the Typelevel stack.

The second part of the train station blog post series is out!🚂 This time we are going to improve our Tagless Final code with a great toolkit called Tofu.🚀 #scala #zio #tofu scala.monster/train-station-…

Can't wait for the Scala 3 `derives` feature? Try `derevo`, another killer lib from the authors of `tofu`. A fresh release has reached Maven Central. Now with support for `estatico/scala-newtype` and basically any other Scala 2 newtypes. github.com/tofu-tf/derevo… #tofu #derevo

If you are writing Tagless Final code you might be interested in this release: * Add linting of unused context bounds (via -Wunused:synthetics or -Wunused:params) (#9346) — thank you som-snytt!

A first draft is already available! Let me know if you would be interested in reviewing it. In exchange, you'll get the book and any future updates, and you'll be thanked in the acknowledgments section 🙇🏻‍♂️

If you feel more comfortable reading blog posts in Chinese, you are welcome to read a translation of the #scala #apachepulsar event-driven train station blog post here - infoq.cn/article/iRweHi…

Highly recommended! This book is a great way to start your journey with Tagless Final. As a great bonus you will learn advanced techniques with Monocle, Tofu and derevo.

🚨 Monocle 3 is finally available! 🚨 * new Focus macro (mostly for Scala 3) * andThen, a single method to compose optics * inheritance between optics * tonnes of API simplification and deprecation * new organisation: dev.optics github.com/optics-dev/Mon… #Scala #optics
