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

TL;DR​

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

  • Scala 2.13.4 support.
  • Show implicit conversions and classes.
  • Navigating stacktrace in debug console.
  • New troubleshooting page.

Show implicit conversions and classes​

Last release introduced the option to display additional data inferred from the code to a user. Starting with this release it's also possible to show implicit conversions and classes, which can be enabled by the additional showImplicitConversionsAndClasses setting. Moreover, Visual Studio Code extension has 3 new commands to toggle all these new options, which enables users to quickly peek at the additional information about their code and then turn it back off. All these commands can be bound to a shortcut to further improve the user experience.

implicits

Any editor that allows for quickly changing these settings will also benefit from this change, as the file's decorations are refreshed instantly upon changing any of those settings.

Previously, it was possible to navigate a stacktrace using the Analyze stacktrace command which was added in the v0.9.4 release. It turns out, we can reuse the same mechanism to show file links in the Debug Console in Visual Studio code:

navigate-stacktrace

This was achieved by adding additional information to the output already sent to the editor, so this additional file links should also be reused by any other DAP clients.

Troubleshooting​

As an addition to these new features, we've also recently added a new troubleshooting page that should answer the most basic questions you can have. As the page is fairly new we would appreciate any help in improving it so let us know if you feel anything is missing.

Miscellaneous​

  • Fix continuous compilation when opening tree view in sbt BSP
  • Add 0.27.0-RC1 back to supported versions
