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.
Doing this is no problem whatsoever, you'll have to use the functionality of the path-class. It has all the primitives to code this [and any other kind of manipulation of paths] your-self, coz that's what you'll have to do. See https://en.cppreference.com/w/cpp/filesystem/path/parent_path, f.e. but there might be a few other bits and bobs that are equally or more suited for coding the solution to your specific problem. degski -- *"Big boys don't cry" - **Eric Stewart, Graham Gouldman*
