Does the shell evaluation rely on NIX_PATH internally? #15
Description
I am using nilla on a non-nixos system. I followed the guidance posted in #5 to configure a standalone home-manager configuration under the output systems.home.username@host.result.config.home.activationPackage`.
I wanted to add a shell to my nilla.nix file to have npins and nilla-cli available:
# nilla.nix
let
pins = import ./npins;
nilla = import pins.nilla;
in
nilla.create ({ config }:
let
loaders = {
home-manager = "flake";
};
settings = {
nixpkgs = {
configuration = {
allowUnfree = true;
};
};
nixpkgs-unstable = settings.nixpkgs;
};
in
{
includes = [
./nilla
"${pins.nilla-nixos}/modules/nixos.nix"
];
config = {
# Generate inputs from npins dependencies.
inputs = builtins.mapAttrs
(name: pin: {
src = pin;
loader = loaders.${name} or (config.lib.modules.never { });
settings = settings.${name} or (config.lib.modules.never { });
})
pins;
# Generate home-manager configurations.
generators.home = {
username = "me";
folder = ./homes;
args.inputs = config.inputs;
modules = [
./nilla/modules/home
];
};
# Default shell for config development.
shells.default = {
systems = [ "x86_64-linux" ];
shell = {
mkShell,
npins,
...
}:
mkShell {
packages = [
npins
];
};
};
};
})
I get the following error when running nix run github:nilla-nix/cli shell -- -v --show-eval-commands:

Welcome to fish, the friendly interactive shell
Type help for instructions on how to use fish
The problem is that the npins binary is also not available inside the new shell. I am entering the shell though:
$ echo $IN_NIX_SHELL
