Offline-first nixpkgs lookup tools
This repository contains tools dedicated to search for Nix
derivations and NixOS modules in your local nixpkgs
channel. Think of it as an offline alternative to https://search.nixos.org.
Building
Building the packages requires at least Go 1.20
$ go build ./cmd/nix-search
$ go build ./cmd/nixos-search
nix-search
nix-search
searches for Nix derivations in your local
nixpkgs
repository. The package list is compiled using
nix-env
, and cached in
~/cache/nix_search.gz
.
Creating the cache is done with the command:
$ nix-search -index
The cache file stores the version of nixpkgs. nix-search will warn you if the cache needs rebuilding (for example following a channel update).
Searching for derivations can be done like this:
$ nix-search firefox
Subderivations can be searched using the -category
argument.
$ nix-search -category python311Packages requests
nixos-search
nixos-search
searches for NixOS options. Each run will
automatically build the NixOS documentation's options.json
file, and search for options in it.
Example usage:
$ nixos-search bluetooth
