增加精神汇编错误
boost spirit compilation error
我试图第一次使用boost :: Spirit，并且我正在以一些我不了解解决方案的汇编错误。
似乎暗示它是关于我正在使用的船长，但是我到处都在使用相同的船长，我尝试了许多不同的船长配置，它们都没有工作：（
我的示例文件如下：
#include <boost/spirit/include/qi.hpp>
namespace qi = boost::spirit::qi;
namespace ascii = boost::spirit::ascii;
template <typename Iterator>
struct Grammar: qi::grammar<Iterator, std::vector<std::string>, ascii::space_type>
{
Grammar(): Grammar::base_type(ident_list)
{
ident = qi::lexeme[*qi::alnum];
ident_list = *ident;
}
qi::rule<Iterator, std::vector<std::string>, ascii::space_type> ident_list;
qi::rule<Iterator, std::string, ascii::space_type> ident;
};
int main()
{
Grammar<std::string::const_iterator> grammar;
std::vector<std::string> result;
std::string string_to_parse = "My list of ident";
std::string::const_iterator start = string_to_parse.begin();
std::string::const_iterator end = string_to_parse.end();
phrase_parse(
start,
end,
grammar,
ascii::space,
result
);
return 0;
}
这是汇编错误：

这个char_class难道不转换为此LILLEAL_STRING？仅当我引入中间规则（此处为" esiden"）时，该错误才发生，如果我定义：
ident_list = *qi::lexeme[*qi::alnum]
它可以很好地编译。
规则上的签名略有错误：
qi::rule<Iterator, std::vector<std::string>, ascii::space_type> ident_list;
qi::rule<Iterator, std::string, ascii::space_type> ident;
可能应该是
qi::rule<Iterator, std::vector<std::string>(), ascii::space_type> ident_list;
qi::rule<Iterator, std::string(), ascii::space_type> ident;
// and also
struct Grammar: qi::grammar<Iterator, std::vector<std::string>(), ascii::space_type>
现在编译。
更多注意：只要ident是词汇，您就可以将船长从中放下（请参阅Boost Spirit Skipper问题）。
还有另一个错误，因为它匹配*qi::alnum，这意味着0个字符是匹配的。您将要使用至少1个字符：+qi::alnum。
这是一个有效的样本（这也显示了我首选将船长编码到语法中的方法，因为它通常是语法的一部分）：
活在coliru
#include <boost/spirit/include/qi.hpp>
namespace qi = boost::spirit::qi;
template <typename Iterator> struct Grammar : qi::grammar<Iterator, std::vector<std::string>()> {
Grammar() : Grammar::base_type(start) {
using namespace qi;
ident = +alnum;
ident_list = *ident;
start = skip(ascii::space) [ident_list];
}
private:
qi::rule<Iterator, std::vector<std::string>()> start;
qi::rule<Iterator, std::vector<std::string>(), qi::ascii::space_type> ident_list;
qi::rule<Iterator, std::string()> ident;
};
int main() {
Grammar<std::string::const_iterator> grammar;
std::vector<std::string> result;
std::string const input = "My list of ident";
auto start = input.begin(), end = input.end();
if (parse(start, end, grammar, result))
std::cout << "Parsed " << result.size() << " tokensn";
else
std::cout << "Parsing failedn";
if (start != end)
std::cout << "Remaining unparsed input: '" << std::string(start,end) << "'n";
}

在如此简单的语法中，请考虑将其插入：

namespace qi = boost::spirit::qi;
int main() {
for (std::string const input : { "My list of ident", " My list of ident " }) {

std::list<std::string> result;

std::cout << "Parsed " << result.size() << " tokensn";

std::cout << "Parsing failedn";
