... So, add Boost.Parameter and you get

That's nice, but I think we can do better...
And then there's
directory_range('some_path') | filtered(predicate1) | filtered(predicate2) ...
Yes, and that's the direction I'm planning to explore.
I'm just now setting up to try out such suggestions.
You may find that post-hoc filtering with "|" is not going to allow you to avoid traversing into subdirectories that will ultimately be filtered out. On the other hand, maybe it's possible to do something with expression templates that saves you from that problem. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
