Describe the bug

Inside Neovim, I am not seeing any relevant completion, or even hover information, while editing a flake.

I do see LSP progress events emitted by nixd (below), but no relevant LSP feature seems to be functional.

# lsp progress
nixd [evaluating nixpkgs entries]
nixd [evaluating nixos options]
nixd [evaluating nixpkgs entries] evaluated nixpkgs entries
nixd [evaluating nixos options] evaluated nixos options

Configuration

None (nvim-lspconfig's default)

To Reproduce

  1. Open a Nix shell that includes the nixd package from Nixpkgs:

    $ nix shell 'nixpkgs#nixd'

  2. Add the following line to Neovim's init.lua, assuming that the neovim/nvim-lspconfig plugin is installed:

    require "lspconfig".nixd.setup {}

  3. Open the following flake.nix at https:/antoineco/dotfiles/blob/ae64add/nix/flakes/shells/go in Neovim.

  4. Attempt to complete something from the nixpkgs input variable, or to hover an attribute from it.

Expected behavior

  • The language server offers completion options for the flake's inputs and outputs attributes.
  • The language server offers information about attributes upon performing a LSP hover.

Screenshots

Example: no completion of nixpkgs.outputs.lib or nixpkgs.outputs.legacyPackages:

As an additional information, I am observing the same behaviour using the output of github:nix-community/nixd#nvim (nvim-lsp command) in a development shell:

Seems to be an unimplemented feature.

Ah right, I just stumbled upon https:/nix-community/nixd/blob/2.3.0/nixd/docs/features.md. I did not understand that nixd was only providing inlay hints and semantic highlights. Sorry for the noise!

Note that https://www.reddit.com/r/NixOS/s/Tsp4msODn3 is claiming that these features are in fact implemented, just to provide context about where I'm coming from.

Note that https://www.reddit.com/r/NixOS/s/Tsp4msODn3 is claiming that these features are in fact implemented, just to provide context about where I'm coming from.

Currently only some idioms in Nix language are implemented. So it can be expected that nixd cannot deal with the general case (at least for now).

I'd like to reopen this issue because the reporting is valid and maybe we'd like to have this feature in the future.

I noticed this in my VsCode as well; my project is flake based and it only seems to go to definition of where it's declared in my flake not any further.
