For full details: https://github.com/scalameta/metals/milestone/88?closed=1

Metals is a language server for Scala that works with VS Code, Vim, Emacs, Zed, Helix and Sublime Text. Metals is developed at the Scala Center and VirtusLab with the help from contributors from the community.

TL;DR​

Check out https://scalameta.org/metals/, and give Metals a try!

Support for kyo-test​

Thanks to Matej Cerny for adding support for kyo-test.

Metals should now support running and discovery of kyo-test.

Experimental jar filesystem support (VS Code only)​

Previously, when looking inside a source jar file, Metals would show the contents of a specific file as a simple virtual document. This meant you couldn't see the actual path to the file. No breadcrumbs or additional navigation inside the file would be possible.

This version of Metals introduces a new experimental flag that will allow you to browse the contents of a jar file as a filesystem with breadcrumbs available. You can also browse the source jars from the metals tree view.

To turn it on you need to set the metals.experimentalJarFileSystemEnabled setting to true.

This is a VS Code (also Cursor) specific feature.

  • improvement(mcp): suggest import-build when no build target is found (matejcerny)
