Hello I am wondering whether it is possible to do this type of regex:

I have certain characters representing okjects i.e. #,@,$ and operations that may be used on them like +,-,%….. every object has a different set of operations and I want my regex to find valid pairs.

So for examle I want pairs #+, #-, $+ to be matched, but yair $- not to be matched as it is invalid.

So is there any way to do this with regexes only, without doing some gymnastics inside language using regex engine?
