I am having a bit of trouble understanding how to install language servers for helix using home-manager. The official wiki points to the programs.helix.languages option, but the example provided there runs into an error:
trace: warning: The syntax of programs.helix.languages has changed
Plus, running helix --health python for example, displays that (of course) no language server is installed, but also that the LSP is not on $PATH. This worries, since installing the LSP the nix way will, as far as I understand, not expose the LSP executable to $PATH.
Any help or guide is appreciated.

Is your sys config flaked?
Yep. I’m not sure it helps at all showing it here, but here it is:
{
description = "flake for my-NixOS";
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/release-23.05";
home-manager.url = "github:nix-community/home-manager/release-23.05";
home-manager.inputs.nixpkgs.follows = "nixpkgs";
};
outputs = { nixpkgs, home-manager, ... }@inputs: {
nixosConfigurations = {
my-NixOS = nixpkgs.lib.nixosSystem {
specialArgs = { inherit inputs; };
system = "x86_64-linux";
modules = [
./hosts/my
# Home manager
home-manager.nixosModules.home-manager
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
home-manager.users.darkness = import ./home;
}
];
};
};
};
}

The latest release of Helix changed the structure of the LSP configuration, since it now supports multiple-LSP per language. You’ll need to make sure your configuration, or whatever is creating it, reflects these changes.
Ryan’s setup works for me:
Make it a flake input:
helix.url = "github:helix-editor/helix/23.05";
and then a universal package in config:
{ config, pkgs, lib, helix, ... }:
........................................
environment.systemPackages = with pkgs; [
helix.packages."${pkgs.system}".helix
.........
