Metals is a language server for Scala that works with VS Code, Vim, Emacs and Sublime Text. Metals is developed at the Scala Center and VirtusLab with the help from contributors from the community.
Help us make Metals even better by informing us on any issues or missing features. It's as simple as creating a π bug report or a π feature request in the Metals GitHub repository.
TL;DRβ
Check out https://scalameta.org/metals/, and give Metals a try!
- Bazel support
- Run for Native and JS platforms
- Metals view for uncompiled changes
- LSP Progress support
Bazel supportβ
This release brings support for using Bazel as a build tool with many features
like completions and go-to-definition
working out of the box. To have the
features working also for dependencies, make sure to enable fetch_sources
for
library dependencies in Bazel definition.
The initial work on Bazel support was started by kpodsiad, continued on by tanishiking, and finally brought to completion by jkciesluk, with tgodzik contributing additional improvements to the area.
Completions in a Bazel project.
Hover and go to definition in a Bazel project.
You can get the slightly more advanced features working by enabling SemanticDB in your project. Simply add the following content to your build:
-
in your
BUILD
file:load("@io_bazel_rules_scala//scala:scala_toolchain.bzl", "scala_toolchain")
scala_toolchain(
name = "semanticdb_toolchain_impl",
enable_semanticdb = True,
semanticdb_bundle_in_jar = False,
visibility = ["//visibility:public"],
)
toolchain(
name = "semanticdb_toolchain",
toolchain = "semanticdb_toolchain_impl",
toolchain_type = "@io_bazel_rules_scala//scala:toolchain_type",
visibility = ["//visibility:public"],
) -
and in your
WORKSPACE
file:register_toolchains(
"//:semanticdb_toolchain",
)
Adding SemanticDB to a Bazel project.
Enabling SemanticDB in your Bazel project will allow you to use such features as go to references.
Go to references in a Bazel project.
You can read more about Metals current support for Bazel and setting it up in documentation. Our Bazel support is still in the early stages but we'd love to get your feedback!
Run for Native and JS platformsβ
Thanks to tgodzik, starting with this release you
can run your code using native
and js
platforms straight from the editor.
Just click on the run
code lens or trigger debug run in any other way
appropriate for your editor of choice.
Running a Scala Native program using code lenses.
Metals view for uncompiled changesβ
In the previous release, metals view was enhanced and brought to Scala 3. You can read more about that here. The feature was further improved by tgodzik, and now the information about workspace symbols is updated as you write, instead of on compile as before.
Tree view updating while typing.
LSP Progress supportβ
For clients that do not support metals status, slow tasks notifications can now also be available via LSP Progress thanks to work done by keirlawson.
