I am trying to use both unstable and stable repo for packages. I want to pick and choose which packages will be from unstable and which will be from stable. This is my flake.nix file:
{
description = "Nixos config flake";
inputs = {
nixpkgs.url = "nixpkgs/nixos-23.11";
nixpkgs-unstable.url = "nixpkgs/nixos-unstable";
home-manager = {
url = "github:nix-community/home-manager/release-23.11";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = { self, nixpkgs, nixpkgs-unstable, home-manager, ... }:
let
lib = nixpkgs.lib;
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
pkgs-unstable = nixpkgs-unstable.legacyPackages.${system};
in {
nixosConfigurations.default = lib.nixosSystem {
inherit system;
modules = [ ./hosts/default/configuration.nix ];
specialArgs = { inherit pkgs-unstable; };
};
nixosConfigurations.plasma = lib.nixosSystem {
inherit system;
modules = [ ./hosts/plasma/configuration.nix ];
specialArgs = { inherit pkgs-unstable; };
};
homeConfigurations = {
name = home-manager.lib.homeManagerConfiguration {
inherit pkgs;
modules = [ ./home.nix ];
extraSpecialArgs = { inherit pkgs-unstable; };
};
};
};
}
and this is my home.nix file:
{ config, lib, inputs, pkgs, pkgs-unstable, ... }:
{
# Home Manager needs a bit of information about you and the paths it should
# manage.
home.username = "name";
home.homeDirectory = "/home/name";
imports = [
./modules/home-manager/terminals/kitty.nix
./modules/home-manager/shells/zsh.nix
];
# This value determines the Home Manager release that your configuration is
# compatible with. This helps avoid breakage when a new Home Manager release
# introduces backwards incompatible changes.
#
# You should not change this value, even if you update Home Manager. If you do
# want to update the value, then make sure to first check the Home Manager
# release notes.
home.stateVersion = "23.11"; # Please read the comment before changing.
# The home.packages option allows you to install Nix packages into your
# environment.
# # Adds the 'hello' command to your environment. It prints a friendly
# # "Hello, world!" when run.
# # It is sometimes useful to fine-tune packages, for example, by applying
# # overrides. You can do that directly here, just don't forget the
# # parentheses. Maybe you want to install Nerd Fonts with a limited number of
# # fonts?
# (pkgs.nerdfonts.override { fonts = [ "FantasqueSansMono" ]; })
# # You can also create simple shell scripts directly inside your
# # configuration. For example, this adds a command 'my-hello' to your
# # environment:
# (pkgs.writeShellScriptBin "my-hello" ''
# echo "Hello, ${config.home.username}!"
# '')
home.packages =
(with pkgs; [
racket
mpv
vlc
hello
tree
(discord.override {
# remove any overrides that you don't want
withOpenASAR = true;
withVencord = true;
})
teams-for-linux
evince
neofetch
vesktop
nixfmt
opentabletdriver
unzip
zsh-powerlevel10k
zsh-autocomplete
zsh-autosuggestions
zsh-syntax-highlighting
])
++
(with pkgs-unstable; [
minecraft
vscode
ani-cli
opentabletdriver
]);
# Home Manager is pretty good at managing dotfiles. The primary way to manage
# plain files is through 'home.file'.
home.file = {
# # Building this configuration will create a copy of 'dotfiles/screenrc' in
# # the Nix store. Activating the configuration will then make '~/.screenrc' a
# # symlink to the Nix store copy.
# ".screenrc".source = dotfiles/screenrc;
# # You can also set the file content immediately.
# ".gradle/gradle.properties".text = ''
# org.gradle.console=verbose
# org.gradle.daemon.idletimeout=3600000
# '';
};
# Home Manager can also manage your environment variables through
# 'home.sessionVariables'. If you don't want to manage your shell through Home
# Manager then you have to manually source 'hm-session-vars.sh' located at
# either
#
# ~/.nix-profile/etc/profile.d/hm-session-vars.sh
#
# or
#
# ~/.local/state/nix/profiles/profile/etc/profile.d/hm-session-vars.sh
#
# or
#
# /etc/profiles/per-user/name/etc/profile.d/hm-session-vars.sh
#
home.sessionVariables = { EDITOR = "nvim"; };
# Let Home Manager install and manage itself.
programs.home-manager.enable = true;
# The below code does work.
nixpkgs = {
config = {
allowUnfree = true;
allowUnfreePredicate = (_: true);
};
};
# The below code does NOT work.
nixpkgs-unstable = {
config = {
allowUnfree = true;
allowUnfreePredicate = (_: true);
};
};
programs.git = {
enable = true;
userName = "name";
userEmail = "email";
extraConfig = {
init.defaultBranch = "main";
};
};
}
Right now, in home.nix, the nixpkgs config to allow unfree works perfectly fine. However, since I am using unstable branch, I also need to tell nix to allow unfree for that branch. How can I do that? My attempt to get it to work with the nixpkgs-unstable = {…} doesn’t work because nixpkgs-unstable doesn’t exist.
