Easy fix is to differentiate between the "[", "[[", "\[", and "\[[" in
the lexical analysis phase so that each is assigned a representative
symbol (and ditto that for their partners).
then you have
exp -> LEFT_BRACKET exptext RIGHT_BRACKET
code -> DBL_LEFT_BRACKET codetext DBL_RIGHT_BRACKET
You could do it with the gramatic syntax, but it would be trickier.
What tools are you using? Are you hand coding? Is your parser
recursive decent? Is this a homework assignment?
