Hi,

I'm developing a VS Code extension for my DSL developed with Xtext.
I am currently working on Hover Services for my language server.

Do you know if it is possible to add content when hovering over the keywords to add a short description?
For example in xtext-languageserver-example, when we hover over the keyword "Hello", we would have a description that is displayed.

I tried to make a CustomHoverServices which extends from HoverServices, overriding the getContents method and filtering the elements by Keyword but it didn't work.

Do you have an idea ?

Thank you.

I currently have a UI plugin that already has the ability to hover over keywords in an Eclipse runtime.
I'm looking to reproduce this behavior in Visual Studio Code through my language server, by adding the functionality in my IDE plugin.

I tried to exploit your example here to do this but was unsuccessful.

Do you need more information about my implementation?
