Improved support for braceless Scala syntax IntelliJ IDEA can now desugar braceless Scala code properly, and it handles refactorings where the “fewer braces” feature is used. It also supports braceless syntax in worksheets and correctly interprets indentation when you move extensions methods up and down in your code. The indentation of the extension method is carried over correctly Streamlined import management If you use compiler-based highlighting, until now all imports have been marked as used. Scala 3.3, however, introduced a new compiler option, -Wunused:imports. The IDE c

A full-blown IDE is one of the most complicated applications you can find on an average laptop. This is why we – the Scala plugin team at JetBrains – from time to time receive reports that our product lags in certain situations or works slowly in general. In some of these cases we can help, but in others – for example, when your codebase is big and complicated, or when your machine is old – there is not much we can do. Instead, there are some things you can try yourself to improve your IntelliJ IDEA and the Scala plugin experience, like implementing configuration tweaks and maintaining good co

This release has been again focused on Scala 3, but there are also quite a few other improvements. Better Scala 3 support In v2022.3, we’ve introduced a large number of upgrades to provide better Scala 3 support. The IDE now supports parameter untupling and quoted patterns, and it features many improvements to the support for match types and type variables. There is now type inference for type variables, and they are parsed correctly for pattern-matching purposes. Named arguments in the trait constructor are now correctly handled, and you can use an action to quickly create a Scala 3 enu

ScalaCon 2022 has come and gone. It started on Tuesday, October 4, and over the course of 4 days, the audience had the chance to enjoy 21 talks and 2 keynotes. JetBrains was a Gold Sponsor of the event, which meant that we, the Scala Plugin team, had the opportunity to participate, present a lightning talk, and answer questions from attendees who came to our virtual booth.

This release has been again focused on improving Scala 3 support, but there are also a few other improvements. Better Scala 3 support As of v.2022.2, IntelliJ IDEA can read match types from .tasty files, properly parse them, resolve type variables, use them as type arguments, support inspections, and show types as text. On top of that, we’ve added support for Option-less extractors, type lambdas and polymorphic function types, type-level compiler intrinsics, and ? as a wildcard together with _ in Scala 2.13.9 and 2.12.16. Copy-pasted code is also now properly indented. Compiler
