Hi Stefan,

Hello,

For debugging purposes, I want to get the current state name as a string. For this purpose I found the class get_state_name in the tools section of the backend.

Unfortunately there is no example on how to use this method in the documentation nor anywhere else; and the extensive use of templates makes it very difficult for me to infer this.

I am especially confused about the argument boost::msm::wrap<StateType> const& of the call operator. What do I have to provide her? Could anybody please post a short example how to this?

Kind regards,

Stefan Wiehler

It is documented (http://svn.boost.org/svn/boost/trunk/libs/msm/doc/HTML/re02.html), but it's clearly insufficient. Please allow me to correct it (and add to the doc). Admittedly, as a metaprogramming debugging tool it's a bit hard to read (it's ok if you don't get, it just has to fill the string name_of_open). I just tried this unsing VC10 and boost 1.52. I suppose you already have your state id (for ex. using current_state()) and it has id 1: // we need a fsm's table typedef player::stt Stt; typedef msm::back::generate_state_set<Stt>::type all_states; //all states std::string name_of_open; // id of Open is 1 // fill name_of_open for state of id 1 boost::mpl::for_eachmpl::placeholders::_1 > (msm::back::get_state_name<Stt>(name_of_open,1)); std::cout << "typeid-generated name Open is: " << name_of_open << std::endl; HTH, Christophe
