Error Wrapper

Inheritance from the package’s classes allows you to handle errors of any level in a uniform way and automatically log error messages if desired. This is a familiar routine, a fraction of which I wanted to reduce:)

Installation

Install from PyPI with:

pip install error-wrapper

Usage

Completely abstract example:)

logger = logging.getLogger(__name__)

class DivNum(ErrorWrapper):

    def test_args_number(self, *args):
        if len(args) != 2:
            self.raise_instance_error(f'{ARG_NUM_ERROR}{len(args)}')
        return

    @run_method_if_no_errors
    def test_args_type(self, *args):
        if not isinstance(args[0], int) or not isinstance(args[1], int):
            self.raise_instance_error(ARG_TYPE_ERROR)
        return

    def div(self, *args):
        self.clear_instance_error()
        self.test_args_number(*args)
        self.test_args_type(*args)
        if self.error:
            return self.error_detail
        try:
            return args[0] / args[1]
        except Exception as e:
            self.raise_instance_exception(e)
            return self.error_detail


# Default creating params: report_prefix=None, exception_name_in_detail=False,
#                          logger=None, auto_logging=False

divnum_with_defaults = DivNum()

divnum_with_auto_logging = DivNum(auto_logging=True, logger=logger)

divnum_with_prefix_in_log_or_error_vessage = DivNum(report_prefix='DevNum instance error: ')
