scalameta
project in VS Code with metals and I'm consistently getting error from sbt: Not a valid command: metalsEnable
. I tried various workarounds found in already reported issues (e.g. scalameta/metals#685) but nothing works...

@BBartosz you can generate programs by constructing trees and printing them with Scalameta. Macros allow you to do roughly the same thing, except you do it during the compilation of your program
How exactly you generate them? I understand that you use quasiquotes to build your tree and then you save it to file, kinda like string?
Hi all, wondering if someone could clarify the behavior of the semanticdb-scalac plugin for me. I'm running this command:
$ ~/Downloads/scala-2.13.1/bin/scalac -Xplugin:$(realpath ~/Downloads/semanticdb-scalac_2.13.1-4.3.0.jar) -Yrangepos -Xplugin-require:semanticdb HelloWorld.scala
I'm expecting to see semanticdb files in META-INF/semanticdb
, but I do not. In fact, if I create the META-INF/semanticdb
directory before running the above command, the semanticdb
directory is deleted.
