In this talk, we'll cover the essentials of macros, why they are useful, why you should care about them, and how to become as good as you need with them for practical purposes.
Scala 3 macros are some of the least understood parts of the language, and some of the most powerful. In this talk, we'll cover the essentials of macros, why they are useful, why you should care about them, and how to become as good as you need with them for practical purposes.
You will understand:
- why inlines are great but often not sufficient
- the mechanics of a macro
- how to manipulate programs as values
- how to surface custom errors in the compiler
- essential pieces you can work with, including terms, symbols, types, trees and expressions
- how to make useful libraries with macros
- practical examples of macros at work
In this talk, I'll look at the different uses to which tagless final is put to, and see what we can learn about when it is useful and when it just gets in the way.
In our talk, we will introduce a novel approach to system design— TypeOps — in which the application and infrastructure layers are fused to provide unprecedented safety and productivity for Scala teams.
In this talk, I'll walk you through coding and design practices I've developed over the years, whilst onboarding new graduates into world of Scala (be it typelevel based API, Spark based ETL, or ML pre and post-processings), and how I made the process easier for people who didn't have much Scala experience beforehand.
Case study. Summary of over a year of experience building AWS lambdas using Scala 3, scala-cli, and GraalVM. Presentation of the open-sourced library providing custom lambda runtime developed for that purpose.
