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

- Scala 2.12.15 and 3.1.0-RC2 support.
- Indent on paste improvements.
- Show TASTy command.
In Metals 0.10.6 we introduced a new feature that would adjust the indentation of any pasted snippet. You can read about it in previous release notes.
The feature was not fully mature and despite our best intentions it could cause a lot of issues for the users. To help with that we introduced two changes.
Firstly, we will now use the current indentation of the cursor and adjust any pasted snippet to use that level of indentation.
For example in case of a simple snippet like:
if we paste it into:
after pasting we will have:
However, if we move the cursor back:
the result will be different:
You can use it to paste anything at the indentation level you need.
Moreover, we also added a new setting
metals.enableIndentOnPaste, which you
can use to turn the feature on and off. Currently, it's off by default. We
highly recommend turning it on, testing out some more and reporting any new
We also included a number of fixes for indentation in the Visual Studio Code extension, which should fix some problems in the Scala 3 optional braces code.
What is TASTy? According to the official Scala documentation:
TASTy is an acronym that comes from the term Typed Abstract Syntax Trees. It's a high-level interchange format for Scala 3, and in this document we'll refer to it as Tasty. Tasty files are generated by the scalac compiler, and contain all of the information about your source code, including the syntactic structure of your program, and complete information about types, positions, and even documentation.
Thanks to kpodsiad, Metals can now show TASTy of
a currently opened file using the new
metals.show-tasty command. However, keep
in mind that currently, this feature works only for Scala 3 sources. You can use
this new command already in nvim-metals and Visual Studio Code.
Big thanks to everybody who contributed to this release or reported an issue!
