I feel like I should mention this article https://stefan-marr.de/2022/10/effortless-language-servers/ linking a paper that describes how to derive the LSP server for any language built on top of GraalVM. And a repo with a language server example. There are some good ideas that we can use.

Effortless Language Servers

Paper comparing low-effort approaches for implementing language servers.

Worth noting that the original TextMate grammar definition (https://github.com/enso-org/enso/blob/develop/tools/enso4igv/src/main/resources/org/enso/tools/enso4igv/enso.tmLanguage.json) was taken from https://github.com/joenash/vscode-enso. Great to see that now, we can build this as an extension straight from Enso, without cloning other repos.

I suggest adding

tools/enso4igv/*.vsix
tools/enso4igv/nbcode/

to the .gitignore.

Nevermind, it's already there!

I switched branches back and was confused 😅 Sorry

Looks great!
