问题 So I have the following qi skipper: template<typename Iterator> struct verilog_skipper : public qi::grammar<Iterator> { verilog_skipper() : verilog_skipper::base_type(skip) { namespace phx = boost::phoenix; skip = qi::ascii::space | qi::eol | line_comment; line_comment = (qi::lit("//") >> *(qi::char_ - qi::eol) >> *(qi::eol)); } qi::rule<Iterator> skip; qi::rule<Iterator> line_comment; }; and the following qi grammar: template <typename Iterator, typename Skipper = verilog_skipper<Iterator>

Boost::Spirit struggle with parsing a String

问题 I'm trying to Parse a String with Boost::Spirit, but i just cannot get it to work. I have no experience with Boost::Spirit since today. The string is composed of commands separated by an ';'. The commands are "INC someInteger" "BOMB firstInteger secondInteger" "MOVE firstInteger secondInteger thirdInteger" "MSG someString" "WAIT" I Managed to get this far: #include <boost/spirit/include/qi.hpp> #include <boost/phoenix/phoenix.hpp> using namespace boost::spirit; int main() { std::string

How to extract trimmed text using Boost Spirit?

由 元气小坏坏 提交于 2019-12-11 01:31:27
问题 Using boost spirit, I'd like to extract a string that is followed by some data in parentheses. The relevant string is separated by a space from the opening parenthesis. Unfortunately, the string itself may contain spaces. I'm looking for a concise solution that returns the string without a trailing space. The following code illustrates the problem: #include <boost/spirit/include/qi.hpp> #include <boost/spirit/include/phoenix_operator.hpp> #include <string> #include <iostream> namespace qi =

Now I use std::string instead of char[5] I have no problem. Can you please
