Hello,

I have nil enabled as the lsp plugin in my doom configuration for editing nix files. The server starts successfully when I open a nix file to edit; I can run code actions and see diagnostics relating to my code, however there is no completion at all.

As a test, I have created a file ~/foo/test.nix with:

{ config, lib, pkgs, ... }:

{
  foo = builtins
}

I then open the file in Emacs, move the cursor to the end of the builtins keyword and insert a .. At that point I would expect completion to appear showing all builtin functions.

I have attached a log of all the IO occuring between Emacs and nil.

nil.log

Note that if I open the same file with the same version of nil in VSCode, completion works.
