Name
nix flake archive - copy a flake and all its inputs to a store

Synopsis
nix flake archive [option…] flake-url

Examples

•   Copy the dwarffs flake and its dependencies to a binary cache:

    # nix flake archive --to file:///tmp/my-cache dwarffs

•   Fetch the dwarffs flake and its dependencies to the local Nix store:

    # nix flake archive dwarffs

•   Print the store paths of the flake sources of NixOps without fetching them:

    # nix flake archive --json --dry-run nixops

Description
FIXME

Options

•   --dry-run
    Show what this command would do without doing it.

•   --json
    Produce output in JSON format, suitable for consumption by another program.

•   --to store-uri
    URI of the destination Nix store

Common evaluation options:

•   --arg name expr
    Pass the value expr as the argument name to Nix functions.

•   --argstr name string
    Pass the string string as the argument name to Nix functions.

•   --eval-store store-url
    The Nix store to use for evaluations.

•   --impure
    Allow access to mutable paths and repositories.

•   --include / -I path
    Add path to the list of locations used to look up <...> file names.

•   --override-flake original-ref resolved-ref
    Override the flake registries, redirecting original-ref to resolved-ref.

Common flake-related options:

•   --commit-lock-file
    Commit changes to the flake’s lock file.

•   --inputs-from flake-url
    Use the inputs of the specified flake as registry entries.

•   --no-update-lock-file
    Do not allow any updates to the flake’s lock file.

•   --no-write-lock-file
    Do not write the flake’s newly generated lock file.

•   --override-input input-path flake-url
    Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file.

•   --recreate-lock-file
    Recreate the flake’s lock file from scratch.

•   --update-input input-path
    Update a specific flake input (ignoring its previous entry in the lock file).
