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 will discuss why it's hard to use the power of RT to test side-effect-heavy apps.
In this talk, I'll walk you through how workflows4s works, how it stands apart from tools like Temporal or Camunda, and why it just might be the better approach for modern, event-driven applications.
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.
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 go through a couple of these projects, and share some of what they've taught me, as well as how their legacy affected other projects in the ecosystem. And who knows, maybe you'll get inspired to try something crazy with Scala too?
During the talk, we’ll build a small effect system using solely Scala 3 context functions step-by-step.
