File system iterator for C++

Question

I'd like a basic C++ STL-like container for the filesystem.

e.g.

std::filesystem::const_iterator i = filesys.begin();  
i->file_name(); i->full_path(), 

etc..

Does something like that exist?

Answer 1

Yes. It exists. Almost similar, atleast which can work with the STL iterators and containers.

boost::filesystem

Example:

path p ("directorypath");
std::vector<path> v;                      
std::copy(directory_iterator(p), directory_iterator(), std::back_inserter(v));
for (std::vector<path>::const_iterator it=v.begin(); it != v.end(); ++it)
{
     std::cout << "   " << *it << std::endl;
}

I suppose, now you would like to look at directory_iterator to discover what else it provides.

Answer 2

Another one is STLSOFT platformstl::readdir_sequence.
