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.
  • --arg-from-file name path Pass the contents of file path as the argument name to Nix functions.
  • --arg-from-stdin name Pass the contents of stdin as the argument name to Nix functions.
  • --argstr name string Pass the string string as the argument name to Nix functions.
  • --debugger Start an interactive environment if evaluation fails.
  • --eval-store store-url The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
  • --impure Allow access to mutable paths and repositories.
  • --include / -I path Add path to search path entries used to resolve lookup paths This option may be given multiple times. Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable.
  • --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-registries

    Don't allow lookups in the flake registries.

    DEPRECATED

    Use --no-use-registries instead.

  • --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.
  • --output-lock-file flake-lock-path Write the given lock file instead of flake.lock within the top-level flake.
  • --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.

    DEPRECATED

    Use nix flake update instead.

  • --reference-lock-file flake-lock-path Read the given lock file instead of flake.lock within the top-level flake.

  • --update-input input-path

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

    DEPRECATED

    Use nix flake update instead.

Logging-related options

  • --debug Set the logging verbosity level to ‘debug'.
  • --log-format format Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
  • --print-build-logs / -L Print full build logs on standard error.
  • --quiet Decrease the logging verbosity level.
  • --verbose / -v Increase the logging verbosity level.

Miscellaneous global options

  • --help Show usage information.
  • --offline Disable substituters and consider all previously downloaded files up-to-date.
  • --option name value Set the Nix configuration setting name to value (overriding nix.conf).
  • --refresh Consider all previously downloaded files out-of-date.
  • --repair During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
  • --version Show version information. Note See man nix.conf for overriding configuration settings with command line flags.
