Returns the filename identified by the path stripped of its extension.

Returns the substring from the beginning of filename() up to and not including the last period (.) character.

If the filename is one of the special filesystem components dot or dot-dot, or if it has no periods, the function returns the entire filename().

Example

#include <iostream>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;

int main()
{
    std::cout << fs::path("/foo/bar.txt").stem() << '\n'
              << fs::path("/foo/.bar").stem() << '\n';

    for (fs::path p = "foo.bar.baz.tar"; !p.extension().empty(); p = p.stem())
        std::cout << p.extension() << '\n';
}

Output:

"bar"
""
".tar"
".baz"
".bar"
