`_valid_command_argument`

[bearomorphism]

Description

I just think it's not a good design to validate and reassign things in a function. The function name itself is confusing.

commitizen/commitizen/commands/check.py

Lines 51 to 62 in 47beadc

	def _valid_command_argument(self):
	num_exclusive_args_provided = sum(
	arg is not None
	for arg in (self.commit_msg_file, self.commit_msg, self.rev_range)
	)
	if num_exclusive_args_provided == 0 and not sys.stdin.isatty():
	self.commit_msg = sys.stdin.read()
	elif num_exclusive_args_provided != 1:
	raise InvalidCommandArgumentError(
	"Only one of --rev-range, --message, and --commit-msg-file is permitted by check command! "
	"See 'cz check -h' for more information"
	)
