Null LS configuration

[C4E5G3]

I apologize if my question is low level. (I have never actually configued nvim in lua).
Is this correct for none-ls? When I open an elixir file, my lsp starts up as null-ls, before realizing that it is elixirls. But then later on it can get confused again...

null-ls.nix

{ pkgs, ... }: {
  
  programs.nvf.settings.vim = {
      extraPlugins = with pkgs.vimPlugins; {
          none-ls = {
              package = none-ls-nvim;
              setup = ''
                  require("null-ls").setup({
                  -- Define sources for linting, formatting, etc.
                      sources = {

                          require("null-ls").builtins.formatting.gofumpt,     -- Go formatter
                          require("null-ls").builtins.formatting.goimports,
                          require("null-ls").builtins.diagnostics.golangci_lint,

                          require("null-ls").builtins.formatting.nixpkgs_fmt,
                          require("null-ls").builtins.diagnostics.statix,



                          require("null-ls").builtins.diagnostics.sqlfluff.with({
                              extra_args = { "--dialect", "postgres" }, -- specify SQL dialect as needed
                          }),
                          require("null-ls").builtins.formatting.pg_format,

                          require("null-ls").builtins.diagnostics.eslint,  -- Example linter
                          require("null-ls").builtins.formatting.prettier, -- Example formatter
                          -- Add more built-ins as needed
                      },
                  })
              '';
          };
      };
  };
}

Using extraPlugins to configure none-ls will conflict with the internal implementation in most cases, because language modules implicitly depend on it. Make sure to check if null-ls is properly disabled (and that you understand the consequences of having it disabled).

P.S. The null-ls module has a sources option.
