我希望我的boost :: spirit-based解析器能够解析文件,将解析后的规则转换为不同的类型,并发出包含它找到的所有匹配项的向量.作为属性发出的所有类型都应该从基类型继承,例如:

#include <boost/spirit/include/qi.hpp>
#include <boost/fusion/adapt_struct.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/foreach.hpp>

struct CommandBase
{
   virtual void commandAction()
   {
     std::cout << "This is a base command. You should never see this!" << std::endl;
     //Boost::spirit seems to get mad if I make this purely virtual. Clearly I'm doing it wrong.
   }
};

struct CommandTypeA : public CommandBase
{
   int valueA;
   int valueB;
   virtual void commandAction()
   {
      std::cout << "CommandType A! ValueA: " << valueA << " ValueB: " << valueB << std::endl; …
