Dotty support in IntelliJ IDEA

on YouTube ↗29m

" summary

IntelliJ Scala plugin already runs Dotty projects from nightly builds, compiles worksheets instantly, shows find-usages and a working debugger, and supports Union/Intersection types and the new Dotty syntax; the plugin downloads snapshots automatically and lets modules be compiled separately as module-level Dotty/Scala compilation. Core work focuses on a new type system registry to swap Scala/Dotty implementations, with syntax parsing added quickly; full type-check parity and a Scala→Dotty migration tool are planned after Dotty’s official release.
