main.cpp

Java写的词法/语法分析器。可生成JAVA语言或者是C++的词法和语法分析器。并可产生语法分析树和对该树进行遍历

#include <iostream>
#include "LangLexer.hpp"
#include "LangParser.hpp"
#include "LangWalker.hpp"

int main()

		LangParser parser(lexer);
		parser.block();
//		antlr.CommonAST a = (antlr.CommonAST)parser.getAST();
		RefAST a = parser.getAST();
		cout << a->toStringList() << endl;
		LangWalker walker;
		walker.block(a);	// walk tree
		cout << "done walking" << endl;
	} catch(exception& e) {
		cout << "exception: "<< e.what() << endl;
