I'm emitting a YAML document as follows: YAML::Node doc; // ...populate doc... YAML::Emitter out; out << doc; Somewhere in the hierarchy of nodes I have a particular sequence that I would like to emit in the Flow style while everything else should use the default style settings. I can't seem to find any way of doing this other than emitting by hand every node and watching out for the nodes I'm interested in. This seems like a high price to pay for something relatively straightforward. Ideally I'd like to be able to tag the Node to say "If you get emitted, do so with the following style". But I

I have a vector3 class. class vector3 { float x, y, z; } node["x"] = vector3.x; node["y"] = vector3.y; node["z"] = vector3.z; The result is x: 0 y: 0 z: 0 I want the result to be: {x: 0, y: 0, z: 0} If use the old API, I can use YAML::Flow to set the style: YAML::Emitter emitter; out << YAML::Flow << YAML::BeginMap << YAML::Key << "x" << YAML::Value << x << YAML::EndMap Using the new API, how can I set the style? I asked this question on a yaml-cpp project issue page: https://code.google.com/p/yaml-cpp/issues/detail?id=186 I got the answer: You can still use the emitter and set the flow style:

How can I read this YAML file with yaml-cpp: sensors: - id: 5 hardwareId: 28-000005a32133 type: 1 - id: 6 hardwareId: 28-000005a32132 type: 4 I can't understand how can I get sensors item, to use it. As I understand sensors is a YAML::Node . How can I get it? Update 1: YAML::Node config = YAML::LoadFile(config_path); const YAML::Node& node_test1 = confg["sensors"]; for (std::size_t i = 0; i < node_test1.size(); i++) { const YAML::Node& node_test2 = node_test1[i]; std::cout << "Id: " << node_test2["id"].as<std::string>() << std::endl; std::cout << "hardwareId: " << node_test2["hardwareId"].as

I'd like to obtain every node in a map without knowing the keys. My YAML looks like this: characterType : type1 : attribute1 : something attribute2 : something type2 : attribute1 : something attribute2 : something I don't know how many "type"s will be declared or what the name of those keys will be. That's why I'm trying to iterate through the map. struct CharacterType{ std::string attribute1; std::string attribute2; }; namespace YAML{ template<> struct convert<CharacterType>{ static bool decode(const Node& node, CharacterType& cType){ cType.attribute1 = node["attribute1"].as<std::string>();
