C++ aide

slt crackman,

voila j'ai trouvé une fonction qui me permet de parser une chaine de caractere, mais tu peu me dire stp quel est la variable qui prend en compte le text a parser, comme ca je rentre ca valeur.

la fonction

#include <boost/spirit.hpp>
#include <fstream>
#include <sstream>
#include <iostream>

struct json_grammar
: public boost::spirit::grammar<json_grammar>
{
template <typename Scanner>
struct definition
{
boost::spirit::rule<Scanner> object, member, string, value, number, array;

definition(const json_grammar &self)
{
using namespace boost::spirit;
object = "{" >> member >> *("," >> member) >> "}";
member = string >> ":" >> value;
string = "\"" >> *~ch_p("\"") >> "\"";
value = string | number | object | array | "true" | "false" | "null";
number = real_p;
array = "[" >> value >> *("," >> value) >> "]";
}

const boost::spirit::rule<Scanner> &start()
{
return object;
}
};
};

int main(int argc, char *argv[])
{
std::ifstream fs(argv[1]);
std::ostringstream ss;
ss << fs.rdbuf();
std::string data = ss.str();

json_grammar g;
boost::spirit::parse_info<> pi = boost::spirit::parse(data.c_str(), g, boost::spirit::space_p);
if (pi.hit)
{
if (pi.full)
std::cout << "parsing all data successfully" << std::endl;
else
std::cout << "parsing data partially" << std::endl;
std::cout << pi.length << " characters parsed" << std::endl;
}
else
std::cout << "parsing failed; stopped at '" << pi.stop << "'" << std::endl;
}

je lé trouvé ici :

c'est dans GRAMMAR le 2 eme code

Merci de ton aide
