I’m revisiting boost::filesystem::path after not using it for a while and wondered whether there is a way to remove parts of a path deeper than a specific directory?
By way of an example, assume I have the following path declared:
boost::filesystem::path path =”d:\\test1\\test2\\test3.txt”
what I want to do is determine whether test2 exists as part of the path and if it does remove everything after and including the found part of the path, so in this case \\test2\\test3.txt would be removed.
I could do it by converting the path to a string, but wondered whether boost::filesystem could do this natively in some way.
Any help appreciated.
Natively, or via the FS API?
I do not have the API right in front of me, but couldn't you peel off
the children nodes to their parents until you found whether the
current node was the match?
I'm not positive, but I am pretty sure FS knows about relative v.
absolute paths, in this regard, as well.

Well, I asked, because you said natively. I thought that was the
point, FS exposes it generically.

You want it to be simpler than the FS API? Again, I do not have the
docs right in front of me. I would start there.
