Metals v1.6.3 - Osmium | Metals We're happy to announce the release of Metals v1.6.3, which brings a number of

And another code action will allow you to quickly switch any map/filter chains into a collect method invocation.

We also have two new code actions. First one will allow you to convert any infix notation to a standard one. This is not enabled for symbolic operators.

If you are using Bazel you might have noticed that until now there was no information about tests and no ability to run them. With this release we will be able to run any tests we want! This will require semanticdb enabled in your workspace.

There is more! If you are a fun of quickly checking currently worked on test case, it's now possible to run the closes test case or method to the current cursor position!

Did you ever get annoyed that you need to reimport everything when copying between different files? Worry no more! Metals will now try it's best to take care of that for you.

Enabling the new closing labels inlay hints will allow you to easily track where each method or class body ends.

New 'copy FQN' command will allow you to get the fully qualified name for any class, method, object or value. This can later be used in places like scaladocs. For example when invoked on the "main" method, you will get a result in for of "com.example.Main#main"

New MCP tool to generate Scalafix rules will allow LLMs to generate refactorings tailored to your workspace.

It's especially useful for any manual repetitive tasks.

Ask your agent to use Metals MCP with the Scalafix rule generation to try it yourself.

New Metals 1.6.3, codename "Osmium", has just been released!

It comes with few interesting new features and we'll take the opportunity to go on a small tour.

We've just released sttp-ai 0.4.0 (formerly sttp-openai): you can now find clients for both OpenAI and Claude APIs. Same as sttp-client, the library works with any #Scala ecosystem: direct-style (synchronous), Future, cats-effect & ZIO. Enjoy!

This concludes our Ox feature tour - hope you've enjoyed it as much as we did!

If you feel a feature is missing, or if you have a suggestion for an integration, just create an issue, we'll be happy to assist:

Ox feature tour, day 19: because it's direct style, integration with OpenTelemetry (metrics+logging+tracing) "just works"! To propagate tracing context inside concurrency scopes, you only need a single switch at your top-level `OxApp`!

Ox feature tour, day 18: `.pipe` and `.tap`, even extremely simple, are suprisingly useful! And there's no overhead: these are inline methods, hence a "zero-cost abstraction". Bonus: discover the `debug`, `.discar` and `.tapException` methods!

More in the docs:
ox.softwaremill.com/latest/basi...

Ox feature tour, day 17: converting exceptions to `Either`s, and vice versa is trivial thanks to the inline `.catching[]` and `.orThrow` methods. A panic at one level, might become an expected error at another!

More in the docs:
ox.softwaremill.com/latest/basi...

Ox feature tour, day 16: we propose error handling based on "panics" (exceptions) and "expected" errors, represented as Eithers. Working with the lattter is ergonomic thanks to Scala's boundary/break, and its Ox-provided specialization to Eithers using `either: and `.ok()`

More in the docs:

Ox feature tour, day 15: Flows provide integration with Kafka, allowing one to implement the common publish-then-commit pattern using an elegant high-level, functional API.

More, in the docs:
ox.softwaremill.com/latest/stre...

Ox feature tour, day 14: declarative concurrency in flows - virtual threads are started (and terminated on error) safely, without ever needing to touch concurrency scopes! Signalling an error is as easy as throwing an exception.

More in the docs:
ox.softwaremill.com/latest/stre...

Ox feature tour, day 13: flows provide I/O integration, declarative concurrency, and reactive streams compatibility!

(2/2) > With these new features, Wasm has much better support for compiling high-level programming languages. Enabled by this, we have seen various new languages popping up to target Wasm, such as Java, OCaml, Scala, Kotlin, Scheme, or Dart, all of which use the new GC feature.

Wasm 3.0 Completed - WebAssembly WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications.

Wasm 3.0 is completed, with major new features like GC and exception handling! Scala is now acknowledged as a language that compiles to WebAssembly 🚀
