Generated by com2ann (slightly patched to avoid also converting assignment type annotations, which require Python 3.6), followed by some manual whitespace adjustment, and two fixes for use-before-define issues: - def set_zulip_client(self, zulipToJabberClient: ZulipToJabberBot) -> None: + def set_zulip_client(self, zulipToJabberClient: 'ZulipToJabberBot') -> None: -def init_from_options(options: Any, client: Optional[str] = None) -> Client: +def init_from_options(options: Any, client: Optional[str] = None) -> 'Client': Signed-off-by: Anders Kaseorg <anders@zulipchat.com>
