Huge thanks to @dragos for his work on a Scala implementation of the LSP (see: https://github.com/dragos/dragos-vscode-scala). This project helped us get quickly started with LSP. Since then, we have refactored the project's original sources to the point where only a few simple case classes remain.

• IntelliJ IDEA: the most widely used IDE for Scala using a re-implementation of the Scala typechecker.
