Neovim: using the builtin formatter erases virtual lines

How are you using the lua-language-server?

NeoVim

Which OS are you using?

Linux

What is the issue affecting?

Formatting

Expected Behaviour

Virtual lines should be preserved. Here is an example (by @whynothugo) with using StyLua as a formatter instead.

Actual Behaviour

Virtual lines get erased. The diagnostics are still there, though. Here is an example of how it looks.

Reproduction steps

1. Setup the nvim-lspconfig and lsp_lines plugins
2. Make sure you see the virtual lines, then format the code
3. Are the virtual lines still there?

Additional Notes

Both examples are demonstrated by using @WhyNotHugo's lsp_lines Neovim plugin. There is a downstream issue.

Riproduci il problema usando nvim-lspconfig e il plugin lsp_lines, seguendo i passaggi di formattazione elencati e confrontando le righe virtuali prima e dopo la formattazione. Esamina la risposta di formattazione del language server e il comportamento dell'integrazione; il lavoro è completato quando la formattazione preserva le righe virtuali mentre i diagnostici rimangono visibili.
