I’m migrating an existing Ace editor project to Monaco Editor, which has few highlight rules set for them, and are used depending on instances. I want to achieve something similar to this in Monaco Editor.

First I thought of simply adding the rules to each new instance, but this would have caused various custom languages being created, which wouldn’t be the case if we could extend it. I went through this issue on github for the same. But In my scenario, I don’t want to extends upon an existing language, but more on two different rulesets. Another option is to write a custom function to extend upon a given use case and combine them together. But I feel like that’s a suboptimal method for the same.
