13207	boost::spirit::istream_iterator unusable with boost::asio::ip::tcp::iostream	Christoper Friedt <chrisfriedt@…>	Joel de Guzman	"Hi, 

I'm really looking forward to using boost::spirit in my next project. Unfortunately, I seem to have hit a roadblock in that the boost::spirit::istream_iterator constructor completely locks up when it is passed a boost::asio::ip::tcp::iostream reference.

I come from a (much stronger) C background, so perhaps I'm missing the greater picture, but in the ""spirit"" of a C++ stream-based API, I would have thought that any input stream would work with spirit's forward iterator - at least that's how I interpreted the documentation.

A really simple example is the following:


{{{
#include <boost/asio.hpp>
#include <boost/spirit/include/support_istream_iterator.hpp>
#include <iostream>

int main( int argc, char *argv[] ) {

	static const int port = 443;

	if ( 2 != argc ) {
		std::cout << ""usage: "" << argv[ 0 ] << "" <fqdn>"" << std::endl;
		std::cout << std::endl;
		std::cout << ""where <fqdn> is e.g. www.google.ca"" << std::endl;
		return 0;
	}

	std::string fqdn( argv[ 1 ] );

	std::cout << ""creating fds.."" << std::endl;

	boost::asio::ip::tcp::iostream fds( fqdn, std::to_string( port ) );

	if ( ! fds ) {
		std::cerr << ""unable to create fds: "" << fds.error().message() << std::endl;
		return 1;
	}

	std::cout << ""creating istream_iterator.."" << std::endl;

	boost::spirit::istream_iterator begin( fds );

	std::cout << ""created istream_iterator!"" << std::endl;

	return 0;
}
}}}

Compile with

g++ -std=c++14 -o foo foo.cpp -lboost_system
