Good news, I just wish Ruby had better DX on Vscode across all platforms. The ecosystem now is broken. Things barely work. All I want is syntax highlight, autocomplete and jump to definition without any ai stuff.
I guess RubyMine is the only proper way to use Ruby.
Agreed, I'm not sure how the github/shopify folks are doing their own work these days. I have to keep one archived extension + 2 others to try and cover the basic feature set you expect. I realize Ruby typing means some things aren't possible, but the fragmented toolset means the simple things keep breaking. I think some sort of 'champion' or company push will be needed to tidy things up at this point. Ironically, Shopify owns one of the Ruby extensions but it is feature incomplete.
There is a good talk about this issue if you are interested, https://www.youtube.com/watch?v=pOuy51ZCGEw
