 AssertInequality | is there a way to set arbitrary options on perSystem? | 19:54:30 |
| AssertInequality | Here are two examples:
Vanilla Flakes
{
description = "Minimal multi-branch example";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-24.05";
nixpkgs-unstable.url = "github:nixos/nixpkgs?ref=nixos-unstable";
flake-utils.url = "github:numtide/flake-utils";
};
outputs =
inputs@{ self
, nixpkgs
, nixpkgs-unstable
, flake-utils
, ...
}:
let
pkgs = import nixpkgs {
system = "aarch64-darwin";
};
in
{
upkgs = import nixpkgs-unstable {
system = "aarch64-darwin";
};
packages."aarch64-darwin" = pkgs;
};
}
Flake Utils
{
description = "Minimal multi-branch example";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-24.05";
nixpkgs-unstable.url = "github:nixos/nixpkgs?ref=nixos-unstable";
flake-utils.url = "github:numtide/flake-utils";
};
outputs =
inputs@{ self
, nixpkgs
, nixpkgs-unstable
, flake-utils
, ...
}:
let
supportedSystems = [
"x86_64-linux"
"aarch64-linux"
"aarch64-darwin"
];
in
flake-utils.lib.eachSystem supportedSystems
(system:
let
pkgs = import nixpkgs {
inherit system;
};
in
{
packages = pkgs;
}) //
flake-utils.lib.eachSystemPassThrough supportedSystems
(system: {
upkgs = import nixpkgs-unstable {
inherit system;
};
});
}
In the Flake Util example, I'm able to build a multi-platform flake that exposes upkgs for each architecture.
Can anyone help me with recreating this minimal Flake Util setup in flake-parts ?

 Bryan | Redacted or Malformed Event | 17:41:20 |
| Bryan | Good afternoon - we've got a large deployment (~45 hosts in each of 3 tiers, each looking ~identical but with differing hostnames and the like) we're hoping to manage with deploy-rs or colmena (we've yet to choose). We've started using flake-parts for integration with other tools (mostly treefmt and numtide/devshell). This has been working well so far and we are making some decent use of the module system to abstract everything well.
We are now looking to handle system abstraction. We know our fleet is entirely x86_64-linux, so we don't require that abstracted at all, but I am struggling to handle the system definition generation. Currently we have a function that we want to import to make the api for definition a bit cleaner, but I am struggling to get it importing without infinite recursion.
Is anyone abstracting their system definitions somehow that might be able to provide pointers? Is there some way to import a library of functions that aren't held to the nixos/flake-parts module schema? | 17:46:26 |
| Bryan | Unfortunately, I can't share much of the code we have now, but I can describe in more detail if that helps anyone. | 17:47:18 |

 tomberek | This can happen when using the module system to define options later used to define other options. Is it possible you are using some output of the final configuration in a conditional somewhere else?
Sometimes, using a simple "import" rather than the module system's "imports" is helpful for re-use. | 00:56:04 |
| tomberek | Anything in the debug output that can help trace the issue. I know it can be hard to read, but sometimes it does tell you exactly what you need to investigate. | 00:56:55 |
| tomberek | Otherwise, feel free to DM if you want to go more in-depth. | 00:57:29 |
