We're excited to announce the release of Metals v1.3.2. This new version not only addresses numerous bugs but also enhances the experience of working with code that does not compile.

For full details: https://github.com/scalameta/metals/milestone/68?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!

Outline compilation​

Metals relies on information produced during compilation for much of its functionality. This limits the usefulness of many Metals features when the code is broken either by providing outdated information or no information if the project was never successfully compiled.

Starting with this release Metals will utilize outline compilation to get current information about not compiling files for Scala 2.12.x and 2.13.x. This should improve the experience of working with not compiling code.

There are a few limitations to this improvement, the biggest being that the information from outline compilation will be only available within the same build target (module).

Further work is being done on a similar approach for Scala 3, which should be available in one of the upcoming releases.

broken-code Completions on not compiling code

Before this release Metals would always use information from SemanticDB to search for references. Since SemanticDB is produced during compilation it would fail to find references for code that didn't compile. Now if SemanticDB information is missing or outdated Metals will fallback to using presentation compiler for reference search for all the files this concerns.

Allow to override debug server startup timeout​

Until this release there was a fixed timeout for debug server startup time set to one minute. This proved to be insufficient for some larger projects and can now be overridden using a server property, e.g. -Dmetals.debug-server-start-timeout=90 increases the timeout to 90 seconds.

This is meant more as a temporary workaround, we also plan to work on decreasing the startup times, as this heavily impacts the user experience.
