nix-index
Quickly locate Nix packages containing specific files by indexing binary caches.
What is nix-index?
nix-index is a command-line tool that indexes files from built Nix package derivations available in binary caches. It solves the problem of quickly identifying which Nix package provides a specific file, such as a binary or library, without needing to manually search through nixpkgs. The tool generates a local database that can be queried via `nix-locate` to find package attribute paths.
NixOS users, Nix package managers, and developers working in Nix environments who need to efficiently locate packages based on file contents. It's particularly valuable for those using shells where command-not-found functionality is desired.
Developers choose nix-index because it dramatically speeds up package discovery by searching pre-built binary caches instead of requiring local builds. Its integration as a command-not-found replacement provides immediate, actionable suggestions when commands are missing in the shell.
