In reply to @lla_dane "Hey folks, I'm trying": 1. don't use outdated Nim compiler, latest is Nim v2.2.4 2. if you use choosenim, please read: https://github.com/nim-lang/choosenim/issues/13 3. install official nim-lang plugin 4. install nimlangserver:`nimble install --useSystemNim nimlangserver@\#head` 5. it will take some time for nimlangserver to start after you open Nim file in vscode
