Do boost::begin() and boost::end() support directory iterators? ie., can you write
void f(boost::filesystem::path&);
boost::filesystem::path some_directory;
std::for_each(boost::begin(some_directory), boost::end(some_directory), f);
If they don't, could they and should they?
Just looking at the docs, I don't think so, nor should it. There are two possible iterators constructable from a path. The directory iterator, which iterates over the files, and the path iterator, which iterators over the components of the path itself. The latter are the ones returned from some_directory.begin() and .end(), and will almost certainly be the ones returned from boost::begin/end. I would consider at making a function that returned a range of the directory iterators and using that instead. Something like: namespace bfs = boost::filesystem; boost::iterator_range< bfs::directory_iterator > \ directory_range( bfs::directory_iterator(path), bfs::directory_iterator() ); std::for_each(boost::begin(directory_range), boost::end(directory_range), f); (Untested, uncompiled, and written by someone who's rarely used range.) -- Anthony Foglia Princeton Consultants (609) 987-8787 x233
