Virtually all the functionality of this package comes from ruby_language_server.
I'm just trying to get the ball rolling.
Why does this crash?
Do you have docker installed? Is the path /usr/local/bin/docker? You can tweak that in the settings...
Did you start typing something before the outline view said there is none available? Because that will crash the parser which will lock up the editor.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
