Examples

• Resolve the nixpkgs and blender-bin flakerefs:

  # nix registry resolve nixpkgs blender-bin
  github:NixOS/nixpkgs/nixpkgs-unstable
  github:edolstra/nix-warez?dir=blender

• Resolve an indirect flakeref with a branch override:

  # nix registry resolve nixpkgs/25.05
  github:NixOS/nixpkgs/25.05

Description

This command resolves indirect flakerefs (e.g. nixpkgs) to direct flakerefs (e.g. github:NixOS/nixpkgs) using the flake registries. It looks up each provided flakeref in all available registries (flag, user, system, and global) and returns the resolved direct flakeref on a separate line on standard output. It does not fetch any flakes.

The resolution process may apply multiple redirections if necessary until a direct flakeref is found. If an indirect flakeref cannot be found in any registry, an error will be thrown.

See the nix registry manual page for more details on the registry.
