Channels Integration

A flake-parts perSystem module that generates instances of nixpkgs from flake inputs.

• config can defined per channel
• overlays can be appled per channel
• an overlay is provided at overlays.channels which adds each channels to pkgs (pkgs.channels.stable.lnav)

Module Options Reference for perSystem.channels

Usage

With the following flake inputs:

{
  inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
  inputs.stable.url = "github:nixos/nixpkgs/release-24.05";
  inputs.latest.url = "github:nixos/nixpkgs";
  inputs.provision-nix.url = "github:kraftnix/provision-nix";
  inputs.provision-nix.inputs.nixpkgs.follows = "nixpkgs";
}

Usage:

{ self, inputs, ... }:
{
  imports = [ inputs.provision-nix.flakeModules.channels ];
  perSystem = { config, ... }: {
    channels.nixpkgs = {
      addChannelsOverlay = true; # default
      config.permittedInsecurePackages = [ "electron-28.3.3" ];
      config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
        "steam"
        "steamcmd"
        "steam-run"
      ];
      overlays = [
        (final: prev: {
          inherit (final.channels.stable)
            prometheus
            vector
            ;
        })
        inputs.provision-nix.overlays.lnav
      ];
    };
    channels.stable = {};
    channels.latest = {};
  };
}
