What I’d actually like to do is get the string name associated with a symbol.
For example, if I had
%token PLUS_ASSIGN "+="
%token MINUS_ASSIGN "-="
...
then I could write something akin to
assignment-expression:
name assignment-op expression
{
std::cout << "Assignment: " << get_name_of_op($2) << "\n";
$$ = build_assignment(get_name_of_op($2), $name, $expression);
}
;
assignment-op: "+=" | "-=" | ... ;
