Equivalent to "Reformat on file save"

[andrew-selvia]

Coming from IntelliJ, I'm accustomed to the Reformat on file save setting which I use to automatically format my code via Scalafmt. Is there an equivalent in the Metals/VS Code ecosystem?

I'm currently approximating via this task I run via sbtn:

~scalafmtAll

but it's a bit slower since it formats the whole project.

Metals uses scalafmt for formatting. There is an option in VSCode in Formatting Editor: Format On Save. This will automatically send a request to metals to perform formatting on the current file. So this should do exactly what you want.
