multi language files

[gdkrmr]

I see that markdown files use correct syntax highlighting for code chunks by default, which I find great. E.g.

```{r}
x <- 1
```

gets highlighted correctly. How does this work with language servers? I have a language server for R that works in .R files but I had to add the R language server manually for markdown files.

[[language]]
name = "markdown"
file-types = ["Rmd","qmd", "md"]
language-servers = ["r", "julia-lsp", "markdown"]

is there a better way to configure this?

The LSP spec doesn't currently support running a server on a fragment of a document - all documents must be backed by files. Sometimes a language server will support handling multiple languages (for example an HTML language server might support JavaScript in script tags) but there isn't a way for us to dynamically dispatch parts of each document to different language servers.
