was convinced that Harper obsidian plug in, as other harper plugins would automatically download harper-ls and core, and run it, but it seems not the case.

Maybe I am dead wrong here. Hence the question, is obsidian plugin stand-alone or do I need internet access to use it?

If later is the case, would there be anyway to make it locally available?

P.S, I was reading the contribution page and if there is anyone working on other languages, it seems like there is none.
Do you happen to know if there is any?
