nix registry pin - pin a flake to its current version or to the current version of a flake URL
nix registry pin [option...] url locked
nixpkgsto its most recent Git revision:
# nix registry pin nixpkgs
Afterwards the user registry will have an entry like this:
nix registry list | grep '^user ' user flake:nixpkgs github:NixOS/nixpkgs/925b70cd964ceaedee26fde9b19cc4c4f081196a
nix flake infowill say:
# nix flake info nixpkgs Resolved URL: github:NixOS/nixpkgs/925b70cd964ceaedee26fde9b19cc4c4f081196a Locked URL: github:NixOS/nixpkgs/925b70cd964ceaedee26fde9b19cc4c4f081196a …
nixpkgsin a custom registry to its most recent Git revision:
# nix registry pin --registry ./custom-flake-registry.json nixpkgs
This command adds an entry to the user registry that maps flake reference url to the corresponding locked flake reference, that is, a flake reference that specifies an exact revision or content hash. This ensures that until this registry entry is removed, all uses of url will resolve to exactly the same flake.
Entries can be removed using
nix registry remove.
start an interactive environment if evaluation fails
The registry to operate on.
Common evaluation options:
Pass the value expr as the argument name to Nix functions.
Pass the string string as the argument name to Nix functions.
The Nix store to use for evaluations.
Allow access to mutable paths and repositories.
Add path to the list of locations used to look up
Override the flake registries, redirecting original-ref to resolved-ref.
