Hi,

What is the status of this library ? Is this a known bug or it is just the example that is not uptodate ? If the latter, can anyone provide a functional version of debug_settings.cpp ?

Thanks !

I dear, problem is that property tree documentation is outdated. I looked at the source code to understand how this library works. It's not so difficult, really. Follows an example from my project, hope it can help you. It writes out a collection of values on a property tree. It is a workaround for the bugged FOREACH into the documentation. If you have some questions, please ask. void ir_builder::add_item( char id, std::string name, double value, bool symbolic, std::vector<unsigned int> nodes, std::map props ) { boost::property_tree::ptree cc; cc.put("id", id); cc.put("name", name); cc.put("value", value); cc.put("symbolic", (int) symbolic); typedef std::vector<unsigned int>::const_iterator ci; for(ci i = nodes.begin(); i != nodes.end(); ++i) cc.add("nodes.node", *i); if(!props.empty()) { boost::property_tree::ptree cprop; typedef std::map::const_iterator ci; for(ci i = props.begin(); i != props.end(); ++i) { cprop.put("name", i->first); cprop.put("value", i->second); cc.add_child("props.prop", cprop); } } ptree_.add_child("circuit.components.component", cc); }
