Hello: I have a client I'm writing, where the server sends data to the client to display as a menu in one instance. I wanted to use boost::spirit to parse this out. So, here's the code. I have three questions: 1) What can I do better/differently? 2) When I parse out my menuitem, if there's no flag, can it be set to 0 by default somehow? 3) Where is menuitem returned? Is there a way I can push it to a queue since I'll have more? My actual parser will look something like: pstart >> item >> *(delem >> item) >> pend; Here is the code I have currently: struct menuitem { std::string name; int flag; int choice; }; BOOST_FUSION_ADAPT_STRUCT( menuitem, (std::string, name) (int, flag) (int, choice)) namespace ascii = boost::spirit::ascii; namespace qi = boost::spirit::qi; //I'd like to just take a char* here, since that's my payload. copying the char* to a std::string will take extra time, is there a way to do that? BOOL Menu::Parse(const std::string &data, int length) { std::string::const_iterator it, itEnd; it = data.begin(); itEnd = data.end(); //we construct a few parsers to make things easier. qi::rule<std::string::const_iterator, char, ascii::space_type> pstart = qi::char_('['); qi::rule<std::string::const_iterator, char, ascii::space_type> pend = qi::char_(']'); qi::rule<std::string::const_iterator, char, ascii::space_type>delem = qi::char_('|'); qi::rule<std::string::const_iterator, menuitem(), ascii::space_type>item = qi::char_("a-zA-Z0-9 -.?!$@") >> qi::char_('(')
-qi::int_ >> qi::char_(':') >> qi::int_ >> qi::char_(')');
if (!qi::phrase_parse(it, itEnd, pstart >> item >> pend, ascii::space)) { return false; } return true; } -- Take care, Ty Web: http://tds-solutions.net The Aspen project: a light-weight barebones mud engine http://code.google.com/p/aspenmud Sent from my toaster.
