This page lists the projects that the Scala Center plans to work on during 2024 Q4. We also post regular updates about our projects on the Scala Contributors forum.

To have more information about our completed projects, please see the quarterly activity reports.

Roadmap for 2024 Q4

The following sections present our plan for the current quarter. Every project description is followed by the concrete results we will deliver and their expected outcome on the Scala community.

Language, Compiler, Standard Library

Our mission is to reduce the number of bugs in the compiler implementation, to help the community to contribute to these tools, and to make sure they evolve in a way that takes into account the needs of the community.

WebAssembly backend for Scala.js

Scala.js 1.17.0 will soon ship with an initial release of the WebAssembly backend. This initial implementation produces correct code (the entire test suite of Scala.js passes) and already contains low-hanging fruit optimizations.

Further work is necessary to unlock better performance. In particular, we will integrate with wasm-opt, a Wasm-to-Wasm optimizer. We already contributed support for the new Exception Handling spec, which our WebAssembly backend relies on.

Scala Improvement Process

The Scala Improvement Process is a process for submitting changes to the Scala language. It aims to evolve Scala openly and collaboratively.

We hold regular committee meetings, which we both coordinate and participate in.

Documentation and Education

Our mission is to improve the structure and content of the website, to create and maintain high-quality online educational content (including online courses), and to help the community to contribute to the website.

Getting Started experience with scala-cli

Now that Scala 3.5.0 has been released with Scala CLI as the default Scala command (SIP-46), we are updating the getting started experience to be based on it. We are creating a new learning path for beginners, recommending the new Scala command. There will be emphasis on important Scala tooling, and how it helps the developer experience.

Standard library API documentation

Compared to other popular languages, the API documentation of our standard library is terse. While that terseness is somewhat compensated by good collections guides, the Scaladoc remains an important source of documentation, as it is available right in our IDEs.

We will start working on a library-wide review of the API documentation, and will make sure it contains comprehensive, standalone information.

Tutorials

We identified tutorials as a form of documentation that is underrepresented in the Scala ecosystem. As part of the Scala Toolkit effort, we have been writing more tutorials to get things done in Scala. We will continue doing so.

Developer Experience

Our mission is to make sure the tools Scala developers use to edit, analyze, navigate through, transform, compile, run, and debug Scala programs are as easy to use as possible, that they work reliably for everyone, and deliver a great developer experience.

sbt 2.x

As mentioned in our past quarterly reports, work on sbt 2.x is well under way.

Many tests now pass after the migration to Scala 3, but much remains to be done. We are working on stabilization, as well as on build caching.

In addition, we intend to work on the loading process. We will investigate how we can make it lighter and faster.

Community and Contributor Experience

Our mission is to create the best environment for the emergence of a strong Scala ecosystem made of high-quality, reliable, libraries that bring simple solutions to complex problems.

Communication

We will conduct actions aiming at communicating a positive image of Scala, and making people excited about it.

  • We will regularly share our achievements and engage the community on our projects via our LinkedIn page.
  • We will speak at tech conferences and local meetups to encourage people to contribute to the Scala ecosystem, and to let non-Scala programmers know about Scala.

Maintenance Work

We will also spend a small part of our time reviewing pull requests, triaging issues, and fix issues for the following projects, to make sure important points are addressed:

  • Scala 3 compiler
  • Scala 2 TASTy reader
  • Scala.js
  • Scaladex
  • Scalafix
  • Scastie
  • Coursier
  • Bloop
  • Metals
  • sbt
  • sbt-dependency-submission
  • scala-debug-adapter
  • tasty-query
  • tasty-mima
