    """Derive a passphrase using the vault(1) derivation scheme.

This is a [`click`][CLICK]-powered command-line interface function,
    and not intended for programmatic use.  See the
    derivepassphrase-vault(1) manpage for full documentation of the
    interface.  (See also [`click.testing.CliRunner`][] for controlled,
    programmatic invocation.)

[CLICK]: https://pypi.org/package/click/

Parameters:
        ctx (click.Context):
            The `click` context.

Other Parameters:
        service (str | None):
            A service name.  Required, unless operating on global
            settings or importing/exporting settings.
        use_phrase (bool):
            Command-line argument `-p`/`--phrase`.  If given, query the
            user for a passphrase instead of an SSH key.
        use_key (bool):
            Command-line argument `-k`/`--key`.  If given, query the
            user for an SSH key instead of a passphrase.
        length (int | None):
            Command-line argument `-l`/`--length`.  Override the default
            length of the generated passphrase.
        repeat (int | None):
            Command-line argument `-r`/`--repeat`.  Override the default
            repetition limit if positive, or disable the repetition
            limit if 0.
        lower (int | None):
            Command-line argument `--lower`.  Require a given amount of
            ASCII lowercase characters if positive, else forbid ASCII
            lowercase characters if 0.
        upper (int | None):
            Command-line argument `--upper`.  Same as `lower`, but for
            ASCII uppercase characters.
        number (int | None):
            Command-line argument `--number`.  Same as `lower`, but for
            ASCII digits.
        space (int | None):
            Command-line argument `--space`.  Same as `lower`, but for
            the space character.
        dash (int | None):
            Command-line argument `--dash`.  Same as `lower`, but for
            the hyphen-minus and underscore characters.
        symbol (int | None):
            Command-line argument `--symbol`.  Same as `lower`, but for
            all other ASCII printable characters except lowercase
            characters, uppercase characters, digits, space and
            backquote.
        edit_notes (bool):
            Command-line argument `-n`/`--notes`.  If given, spawn an
            editor to edit notes for `service`.
        store_config_only (bool):
            Command-line argument `-c`/`--config`.  If given, saves the
            other given settings (`--key`, ..., `--symbol`) to the
            configuration file, either specifically for `service` or as
            global settings.
        delete_service_settings (bool):
            Command-line argument `-x`/`--delete`.  If given, removes
            the settings for `service` from the configuration file.
        delete_globals (bool):
            Command-line argument `--delete-globals`.  If given, removes
            the global settings from the configuration file.
        clear_all_settings (bool):
            Command-line argument `-X`/`--clear`.  If given, removes all
            settings from the configuration file.
        export_settings (TextIO | os.PathLike[str] | None):
            Command-line argument `-e`/`--export`.  If a file object,
            then it must be open for writing and accept `str` inputs.
            Otherwise, a filename to open for writing.  Using `-` for
            standard output is supported.
        import_settings (TextIO | os.PathLike[str] | None):
            Command-line argument `-i`/`--import`.  If a file object, it
            must be open for reading and yield `str` values.  Otherwise,
            a filename to open for reading.  Using `-` for standard
            input is supported.
        overwrite_config (bool):
            Command-line arguments `--overwrite-existing` (True) and
            `--merge-existing` (False).  Controls whether config saving
            and config importing overwrite existing configurations, or
            merge them section-wise instead.
        unset_settings (Sequence[str]):
            Command-line argument `--unset`.  If given together with
            `--config`, unsets the specified settings (in addition to
            any other changes requested).
        export_as (Literal['json', 'sh']):
            Command-line argument `--export-as`.  If given together with
            `--export`, selects the format to export the current
            configuration as: JSON ("json", default) or POSIX sh ("sh").
        modern_editor_interface (bool):
            Command-line arguments `--modern-editor-interface` (True)
            and `--vault-legacy-editor-interface` (False).  Controls
            whether editing notes uses a modern editor interface
            (supporting comments and aborting) or a vault(1)-compatible
            legacy editor interface (WYSIWYG notes contents).
        print_notes_before (bool):
            Command-line arguments `--print-notes-before` (True) and
            `--print-notes-after` (False).  Controls whether the service
            notes (if any) are printed before the passphrase, or after.
        ssh_agent_socket_provider (str):
            Command-line argument `--ssh-agent-socket-provider`.  Names
            an explicit SSH agent socket provider to use, overriding any
            user configuration entries or platform defaults.
