The most straightforward option would probably be to write an LSP wrapper around the stack graphs code. One of the people on my team wrote a very “contrib directory” version of that for internal testing, which lets us test our stack graph rules for a new language in something like VS Code before deploying to production. If someone were to write a more polished version of that, that would be a great way to get code nav into any LSP-compatible editor for any language that supports stack graphs.
