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
Scala 3.6 stabilises the Named Tuples proposal in the main language. It gives us new syntax for structural types and values, and tools for programmatic manipulation of structural types without macros. Can we, and should we, push it to the limit? Of course! let's explore DSL's for config, data, and scripting, for a more dynamic feel.
In this talk, I'll introduce Bazel, exploring its core concepts and the unique aspects that set it apart from other build tools. I'll dive into some typical challenges Scala developers might face when working with Bazel.
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.
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 talk, I will discuss why it's hard to use the power of RT to test side-effect-heavy apps.
