Rikito Taniguchi (@tanishiking) (Weekend OSS contributor to Scala tooling) Tooling
for Scala 3 Reactive System Meetup#7
Scala 3 has landed 🎉
Requirements for transition to Scala 3 Requirements IMO • Stabilizing
the compiler • More learning resources • Libraries support for Scala 3 • Tooling support for Scala 3 👈 today’s topic
Tooling for Scala 3 scalameta based tools • scalafmt •
scala fi x • metals TL;DR Basic Scala 3 supports are already done. Ready to use!
Scalafmt & Scala 3 scalafmt v3 supports Scala 3 Specify
runner.dialect = scala3 .scalafmt.conf
Scalafix & Scala 3 Scala fi x v0.9.28 introduces experimental
Scala 3 support ! https://github.com/liancheng/scala fi x-organize-imports#scala-3 liancheng/scala fi x-organize-imports works with Scala 3
Write your own rule for Scala 3 sbt new scalacenter/scala
fi x.g 8 ↑ generates a rule template that runs both on Scala 2 and Scala 3 You can write both SyntacticRule and SemanticRule
Metals & Scala 3 Metals works with Scala 3 !
Code Completion Code Navigation / Hover Show inferred type (will be available with Scala 3.1.0)
Metals & Scala 3 - Missing features Some advanced features
are still missing in Scala 3 😢 Exhaustive case completion Implement abstract members
Today’s takeaway • Many tools already have basic supports for
Scala 3 ! • Some features are missing… need more e ff ort 💪 • Please try it out, and give us feedback. HAPPY CODING WITH SCALA 3 !!
