The behavior of the program depends on the order of the parameters. Will it take off?

Question

Command line

There is a parser.
Parameters specify what exactly to parse.
Wanting to give the user the ability to choose the output sequence of parsed data, I made the following decision:
The output sequence is indicated by the sequence of parameters.
The parameters themselves, of course, do not change their meaning from the position.
What do you think? Will it take off?

Answer 1

Somehow it's not obvious. Unix does not do this. At least I have not met. And I would be embarrassed if the output suddenly changed from the order.
I would make a separate parameter like --output-format

Answer 2

Not the best idea - get confused, wrap everything in an object or output format string.

Answer 3

Yes I understand. Here is a good utility example: ps.
ps ax produces the same output as ps xa. And if there is a need to change the format, then for this you need to use --format.
