Examples

  • Set the nixpkgs flake identifier to a specific branch of Nixpkgs:

    # nix registry add nixpkgs github:NixOS/nixpkgs/nixos-20.03
    
  • Pin nixpkgs to a specific revision:

    # nix registry add nixpkgs github:NixOS/nixpkgs/925b70cd964ceaedee26fde9b19cc4c4f081196a
    
  • Add an entry that redirects a specific branch of nixpkgs to another fork:

    # nix registry add nixpkgs/nixos-20.03 ~/Dev/nixpkgs
    

Description

This command adds an entry to the user registry that maps flake reference from-url to flake reference to-url. If an entry for from-url already exists, it is overwritten.

Entries can be removed using nix registry remove.
