The biggest advantage for writing a brand new LALR parser I think is that we can make it incremental. I know something about parsing LALR grammars. They would produce some intermediate table from the grammar definition (called status table?) to guide the parser, so that it operates like a finite automata with a stack equipped. If we have that table we can just store the stack and the parser's state to avoid looking back to previous codes. Then we also need a scanner recognizing different types of words. For this we can seek help from tools like Lex. Is C++ an LALR language? Not sure...
