parent_path() with or without trailing slash

Question

As explained in the documentation, the expected output of the following is:

boost::filesystem::path filePath1 = \"/home/user/\";
cout << filePath1.pare         


        

Answer 1

You can use std::filesystem::canonical with C++17:

namespace fs = std::filesystem;

fs::path tmp = "c:\\temp\\";

tmp = fs::canonical(tmp); // will remove slash

fs::path dir_name = tmp.filename(); // will get temp
