nix flake archive

Warning: This program is experimental and its interface is subject to change.

# 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-registries`
  Don't allow lookups in the flake registries. This option is deprecated; use `--no-use-registries`.

- `--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).
