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.
In this talk I will explain the inner workings of an organisation that goes into releasing, maintaining and developing Scala and core parts of its ecosystem.
In this talk, I will show you how to create a programming language from scratch.
