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 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.
Discover how functional programming can inspire creativity with the Scala Sampler, a digital music instrument developed for the Sounds of Scala web audio library.
In this presentation you will learn the source of your issues, and a third way - sanely-automatic derivation which is fast to compile, fast to run, and easy to debug by its users.
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 we'll see how to model a tree structure in Scala, take both imperative and functional approaches to tree traversal algorithms, and do some ASCII art at the same time.
