The instruction "data.put( p/"debug/info/testfail/somefile.hpp" );"
have no data, it is only a path and you are using put... i think you
wanted to say:
ptree::path p('/'); // because by default marcin will continue to use
the '.' i think
data.put( p / "debug/info/testfail" , "somefile.hpp" );
And yes... you are right this have to work, and this other too:
string testName = "testfail";
data.put( p / "debug/info" / testName / "time/hour" , 23 );
And if you not want that the mini parser inside path looks for the '/'
because you are a performance freak, you may...
ptree::ns_path p; // ns: no separator
data.put( p / "debug" / "info" / testName / "time" / "hour" , 23 );
and you force yourself to write this way... this have the advantage
that now you can stop worring about a spurius separator in your keys
that break them without you noticing it. Thinking of it... it seems
that it maybe a little bit error prone to give '.' as a default... and
insted be could:
ptree::path p; // by default, the keys dont get parsed... it behave as
ptree::path p('.'); // now the string you passed to the / operator are
parsed looking for a '.'
ptree::path p('@'); // to parse emails :)
I feel it will save us from some surprises...
