Question

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

#include <iostream>

namespace qi = boost::spirit::qi;
template <typename Iterator>
struct CommandGrammar : qi::grammar<Iterator, std::string(), qi::space_type>
{
    CommandGrammar()
        : CommandGrammar::base_type(text)
    {
        using qi::lexeme;
        using qi::char_;
        using qi::space;

        specialSymbols %= (char_('-') | char_('{') | char_('}') 
                | char_('[') | char_(']') | char_('|') | space);
        text %= *space >> lexeme[+(char_ - specialSymbols)] >> *space;
   }

    qi::rule<Iterator, char(), qi::space_type> specialSymbols;
    qi::rule<Iterator, std::string(), qi::space_type> text;
};

int main() 
{
    std::cout << ">";
    std::string usage;
    std::getline(std::cin, usage);
    CommandGrammar<std::string::const_iterator> commandGrammar;

    std::string::const_iterator iter = usage.begin();
    std::string::const_iterator end = usage.end();

    std::string result;
    bool r = qi::phrase_parse(iter, end, commandGrammar, qi::space, result);
    if (r && iter == end) {
        std::cout << result;
        std::cout << std::endl;
    } else {
        std::cout << "fail" << std::endl;
        std::cout << std::string(iter, end) << std::endl;
    }
}

我需要帮助才能在此代码中找到问题。以下是错误消息的一部分：

Answer 1

The attribute of A | B是boost :: variant。

如果您需要匹配包含任何符号而非“特殊”符号的词汇，则以下内容应执行此操作：

    text %= lexeme[+~char_("-{}[]|")];

（请注意parser skips spaces automatically，当您将qi::space传递给phrase_parse()时，您不必明确跳过它们。）

Boost.Spirit编译器错误
