-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Sorry, this is probably a beginner question, but I'm stuck on it for quite some time. I'm trying to write a small string like parser in which the size of the string is first given. Some thing like: int_ >> repeat(_1)[ char_ ] But I cannot figure out the right way of doing this. The natural: const bool result = boost::spirit::qi::parse(it,str.end(),int_ >> repeat(_1)[ char_ ]); fails to compile (and I tried many variations of val, etc) with no success. If I replace _1 by 10, everything works fine. Another question is that of the associated attribute. From the documentation, I would have expected it to be: typedef std::pair<int,std::vector<unsigned char>> Attribute; but that does not work. I have managed to work around this using a second rule, using an attribute std::vector<char>(int) but then again I do not know how to pass the parameter. 10 works but _1 does not. Any help will be appreciated. Some test code is attached, compile with: g++ -g -std=c++11 -dboost_spirit_use_phoenix_v3 Test.C. Variants are in comment. Thank's in advance for any help.
