efm-langserver

[pivoshenko]

Hi guys 👋🏻 Hope you are ok!

I just started using helix and I absolutely love it 🔥 But I faced a really weird problem with using efm-langserver in helix.
The problem is next: the LSP server shows the error, I am fixing the error but helix still shows the error, so I need to run :lsp-restart so it will disappear. Basically, I need to run :lsp-restart on every code change 🙂

I tested efm-langserver in other editors and it works as expected, so I am only encountering this problem in helix. Would be super grateful if someone could assist ❤️
