[Boost-users] Parsing and evaluate boolean expression

Subject: [Boost-users] Parsing and evaluate boolean expression

Hi All,

I would like to parse and evaluate boolean expression such as (a=b and
c>9). I am following this example at
http://stackoverflow.com/questions/12598029/how-to-calculate-boolean-expression-in-spirit/12602418#12602418.

This is the code for parsing steps:

#include <boost/config/warning_disable.hpp>
#include <boost/spirit/include/qi.hpp>
#include <boost/spirit/include/phoenix.hpp>
#include <boost/spirit/include/phoenix_operator.hpp>
#include <boost/variant/recursive_wrapper.hpp>
#include <boost/lexical_cast.hpp>

namespace qi    = boost::spirit::qi;
namespace phx   = boost::phoenix;

struct op_or  {};
struct op_and {};
struct op_not {};
struct op_equal{};
struct op_not_equal{};
struct op_less{};
struct op_less_equal{};
struct op_greater{};
struct op_greater_equal{};

typedef std::string var;
template <typename tag> struct binop;
template <typename tag> struct unop;

typedef boost::variant<var,
        boost::recursive_wrapper<unop <op_not> >,
        boost::recursive_wrapper<binop<op_and> >,
        boost::recursive_wrapper<binop<op_or> >,
        boost::recursive_wrapper<binop<op_equal> >,

        boost::recursive_wrapper<binop<op_greater_equal> >
        > expr;

template <typename tag> struct binop
{
    explicit binop(const expr& l, const expr& r) : oper1(l), oper2(r) { }
    expr oper1, oper2;
};

template <typename tag> struct unop
{
    explicit unop(const expr& o) : oper1(o) {}
    expr oper1;
};
    template <typename It, typename Skipper = qi::space_type>
    struct parser : qi::grammar<It, expr(), Skipper>
{
        parser() : parser::base_type(expr_)
        {
            using namespace qi;

            expr_  = boolExpr_.alias();

            boolExpr_  = *((compExpr_ >> '|'  >> compExpr_ ) [ _val =

                          |(compExpr_ >> '!'  >> compExpr_ ) [ _val =
phx::construct<binop<op_not > >(_1, _2) ]
                          );
            compExpr_=((compExpr_ >> '='  >> compExpr_ ) [ _val =
phx::construct<binop<op_equal > >(_1, _2) ]
                       |(compExpr_ >> "!="  >> compExpr_ ) [ _val =

                       |(compExpr_ >> '<'  >> compExpr_ ) [ _val =

                       |'(' >> boolExpr_>>')'
                       | varExpr_
                       );
             varExpr_=qi::lexeme[ +(alpha|digit) ];

            BOOST_SPIRIT_DEBUG_NODE(expr_);
            BOOST_SPIRIT_DEBUG_NODE(boolExpr_);

         //   BOOST_SPIRIT_DEBUG_NODE(simple);
         //   BOOST_SPIRIT_DEBUG_NODE(var_);
        }

        private:
        qi::rule<It, var() , Skipper> varExpr_;
        qi::rule<It, expr(), Skipper> boolExpr_, compExpr_, expr_;
};

int main()
{

               std::string inputs="a=b & c>9";
               typedef std::string::const_iterator It;
               It iter=inputs.begin(),end=inputs.end();

               parser<It> p;

                try
                {
                    expr result;
                    bool ok = qi::phrase_parse(iter,end,p,qi::space,result);

                    if (!ok)
                        std::cerr << "invalid input\n";
                    else
                    {
                        std::cout << "result:\t" << result << "\n";
                       // std::cout << "evaluated:\t" << evaluate(result)
<< "\n";
                    }

                } catch (const qi::expectation_failure<It>& e)
                {
                    std::cerr << "expectation_failure at '" <<
std::string(e.first, e.last) << "'\n";
                }

                if (iter!=end) std::cerr << "unparsed: '" <<
std::string(iter,end) << "'\n";

    return 0;
}

Before the parser instantiation, the compilation is ok.  This is  error.
Thank you for any suggestion:
