boost-fusion

Change my codes from QI to X3, and get some compile error with BOOST_FUSION_ADAPT_ADT . I tried boost 1.64 and 1.67, neither of them work. I modified the spirit X3 example rexpr_min , adding getter and setter to struct rexpr , changing the BOOST_FUSION_ADAPT_STRUCT to BOOST_FUSION_ADAPT_ADT , and compile it fail, too. Enviroment: ubuntu 16.04 G++ 5.4, with -std=c++17 flag boost 1.67 Error message: boost/spirit/home/x3/core/detail/parse_into_container.hpp:142:35: error: invalid initialization of non-const reference of type ‘boost::fusion::extension::adt_attribute_proxy<client::ast::rexpr, 0,

Tell me, how can I serialize/deserialize the fusion::vector object type? Thanks. niXman Solved. Like this: http://liveworkspace.org/code/652cab59dc33d280b6d48470c11cfb91 #include <iostream> #include <sstream> #include <boost/fusion/algorithm/iteration/for_each.hpp> #include <boost/fusion/include/for_each.hpp> #include <boost/fusion/container/vector.hpp> #include <boost/fusion/include/vector.hpp> #include <boost/fusion/container/vector/vector_fwd.hpp> #include <boost/fusion/include/vector_fwd.hpp> #include <boost/fusion/container/generation/make_vector.hpp> #include <boost/fusion/include/make

Situation: YAML file containing list of heterogeneous objects by name, like so: object: Foo name: Joe Bloggs age: 26 object: Bar location: UK Objects do not inherit from any base class or share any sort of relationship between each other apart from the fact that they appear to "live" together. This can contain any number of objects. The list of available types can exist in a typelist in the codebase if required. In my C++ land I have the objects: struct Foo { Foo(std::string n, int a) : name(n), age(a) {} std::string name; int age; }; struct Bar { Bar(std::string l) : location(l) {} std:

I am trying to get a serialization module for classes using boost fusion. I have converted my class to a boost::fusion sequence. This example is followed from the slides of the talk of Michael Caisse at boostcon 13 https://github.com/boostcon/cppnow_presentations_2013/blob/master/thu/solving_world_problems_with_fusion.pdf?raw=true The example explained by Michael worked good for struct type. The same could not be applied for class types. What am i missing here ? #include <iostream> #include <typeinfo> #include <string> #include <boost/fusion/include/sequence.hpp> #include <boost/fusion/include

Given a struct like this: struct Foo { int x; int y; double z; }; BOOST_FUSION_ADAPT_STRUCT(Foo, x, y, z); I want to generate a string like this: "{ int x; int y; double z; }" I have seen how to print the values of a Fusion adapted struct, but here I need to print the types and names only. How can I do this mostly simply? I'm not married to Boost.Fusion if there's a better way. llonesmiz I think you can get something similar to what you want by making some slight modifications on the code in this answer . You can easily get the member name using boost::fusion::extension::struct_member_name but

This question is inspired from another topic which poses this question: Find the first value greater than user specified value from a map container which can be solved in several ways. A typical C++03 solution defines a dedicated function (or functor) and pass it to std::find_if as third argument. In C++11, one can avoid defining a dedicated function (or functor), and can instead make use of lambda as: auto it = std:: find_if(m.begin(), mp.end(), [n](const std::pair<std::string, int> & x) -> bool { return x.second > n; } ); which is the accepted answer . I'm still looking for a short and cool
