Scala 3 improvements in Metals (and hopefully, IntelliJ IDEA)

Until recently, with Metals, your code had to be saved after each change for the type checking to take place. And for non-compiling code, there were issues with imports, completion and navigation. The great effort done by the Scala team at VirtusLab is working on solving this problem by creating BTASTy — "best-effort TASTy", a format that can support non-compiling projects!

Purify Your Tests III: Lean, Mean Testing Machine

In the last part we saw how to make our code more declarative, and the tests more functional by introducing type parameters for the inner data flowing through our code. In this part we are going to make our test inputs leaner.

12 years of the com.lihaoyi Scala Platform

The com.lihaoyi platform is an ecosystem of Scala tools and libraries that allow you to write Scala in a way that is easy, rather than powerful. This post discusses the history of the com.lihaoyi platform, how it came about and evolved over the past decade, and what role I think it may play in the future of the Scala language.

Growing Oxen: Channel operators and retries

In this session, Jacek will guide you through two recent additions to Ox that he helped implement: channel operators and retries.We will begin by exploring the principles of interacting with Ox channels, including how to send and receive elements, and how to signal completion or errors. Then, we will build an operator from scratch to understand the guidelines for creating your own operators. In the second part, he will delve into the design process of one of Ox's resiliency mechanisms: retries. We will discuss the goals, choices, and potential future improvements of this feature.

Implementing Multithreading in Scala Native

One of the core Scala domains is scalable, concurrent, or parallel data processing, which typically at some point is powered by JVM Threads. However, the Scala Native - an ahead-of-time compiler and runtime for Scala, was for a long time limited to only a single thread of execution. At first glance, it might have sounded like it a not a big deal. Starting system threads is easy...but then, suddenly, you need to deal with memory models, garbage collections, synchronization, data atomicity, and many more blockers, just to provide the same semantics as JVM ensures.

Tapir Tutorial - part 2: Generating OpenAPI docs

Welcome back! In this episode we'll add auto-generated OpenAPI docs, and browse them using the Swagger editor. We'll also start uncovering some details of how Tapir integrates with various Scala stacks.

Comparing Approaches to Structured Concurrency

There are many approaches to concurrency all with different ways of handling cancellation and errors. Structured Concurrency is an approach that makes typical fan-out and fan-in use cases like races, easier to manage especially when sub-tasks need to be canceled or can produce errors. This talk will compare different approaches across a variety of languages and frameworks. The audience will pick from a long possible list of approaches, including: Scala (with ZIO, Ox, Kyo), Java with Loom, Kotlin (Arrow, Coroutines, Splitties), Python (various), Rust (Tokio or Futures).
