nix-index-database
Weekly updated nix-index database
This repository also provides nixos modules and home-manager modules that add a
nix-index wrapper to use the database from this repository.
The home-manager module also allows integration with the existing command-not-found
functionality.
Demo
$ nix run github:mic92/nix-index-database bin/cntr
cntr.out 978,736 x /nix/store/09p2hys5bxcnzcaad3bknlnwsgdkznl1-cntr-1.5.1/bin/cntrUsage in NixOS
Include the nixos module in your configuration (requires 23.05 or nixos unstable)
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable-small";
nix-index-database.url = "github:Mic92/nix-index-database";
nix-index-database.inputs.nixpkgs.follows = "nixpkgs";
};
outputs = { self, nixpkgs, nix-index-database, ... }: {
nixosConfigurations = {
my-nixos = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
./configuration.nix
nix-index-database.nixosModules.nix-index
# optional to also wrap and install comma
# { programs.nix-index-database.comma.enable = true; }
];
};
};
};
}Usage in Home-manager
- Follow the manual to set up home-manager with flakes.
- Include the home-manager module in your configuration:
{
inputs = {
# Specify the source of Home Manager and Nixpkgs.
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
home-manager = {
url = "github:nix-community/home-manager";
inputs.nixpkgs.follows = "nixpkgs";
};
nix-index-database.url = "github:Mic92/nix-index-database";
nix-index-database.inputs.nixpkgs.follows = "nixpkgs";
};
outputs = { nixpkgs, home-manager, nix-index-database, ... }:
let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
in {
homeConfigurations.jdoe = home-manager.lib.homeManagerConfiguration {
inherit pkgs;
modules = [
nix-index-database.hmModules.nix-index
# optional to also wrap and install comma
# { programs.nix-index-database.comma.enable = true; }
];
};
};
}Additionally, if your shell is managed by home-manager, you can have nix-index
integrate with your shell's command-not-found functionality by
setting programs.nix-index.enable = true.
