Scala Plugin 1.7 for IntelliJ IDEA 15 EAP brings you a number of new features and improvements, among which we’d like to highlight these two:

Inline refactoring for type aliases

Invoked just as any other inline refactoring, by placing the caret on an alias you want to inline and pressing Ctrl+Alt+N.

For now this refactoring is only available for non-parameterized types and for aliases that are used inside of the same class.

Kind projector support

Kind Projector is a Scala compiler plugin that provides an easy way to create type lambdas. Scala 1.7 plugin includes inspection that suggests to rewrite existing lambdas using the Kind Projector function syntax.

You can use the settings under Settings | Editor | Code Style to select whether you want to denote lambdas with the Lambda keyword, or the λ symbol.
Feel free to share your feedback in our discussion forums and issue tracker.

Develop with Pleasure!

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

IntelliJ Scala Plugin 2022.2 Is Out!

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
