Capturing not used options/values

[sn50]

Let's say I need one option -p as a valid option for my program. Everything else is invalid. I need to capture those invalid ones and, let's say, show them to the user. How am I about to do that?

E.g. for program.exe -g -f file I need to get something like {'g'=> null, 'f'=>"file"} in any form available. I couldn't find out how to do that.

Is it possible? If yes, how to achieve it? Thank you in advance.

No, I don't believe that feature is available. What use cases are you thinking of for this feature?

I want my simple program to be able to explicitly inform user on his invalid options entered, since I consider every unpaired option invalid and worth reporting to user.

You could use a ValueList to pick up all additional arguments and then check yourself if that list is empty after parsing. This is done differently depending on branch, what version are you using?
