How to write an IP address parser with actions to fill-in a simple struct?

25 Mar 2010

      I have a rule like this:

rule<> IP_Parser =
   int_p>>'.'>>int_p >>'.'>>int_p >>'.'>>int_p >>
   !( ('/'>>int_p)|(':'>>int_p));

Now I want to extend it that the user can use that parser to fill a
simple struct:

struct IP_address {
   std::string host;
   int port;
   int netmask;
};

and use it this way:

IP_address src;
rule<> Source = str_p("source") >> +space_p >> IP_Parser(src) >>
   *space_p >> ';';

Any ideas how to do that with the old boost::spirit
(boost version 1.35)?
