Method RemoveFileName

tests/gtest/gtest-all.cc:9399–9408

RemoveFileName returns the directory path with the filename removed. Example: FilePath("path/to/file").RemoveFileName() returns "path/to/". If the FilePath is "a_file" or "/a_file", RemoveFileName returns FilePath("./") or, on Windows, FilePath(".\\"). If the filepath does not have a file, like "just/a/dir/", it returns the FilePath unmodified. On Windows platform, '\' is the path separator, other

// not have a file, like "just/a/dir/", it returns the FilePath unmodified.
// On Windows platform, '\' is the path separator, otherwise it is '/'.
FilePath FilePath::RemoveFileName() const {
  const char* const last_sep = FindLastPathSeparator();
  std::string dir;
  if (last_sep) {
    dir = std::string(c_str(), static_cast<size_t>(last_sep + 1 - c_str()));
  } else {
    dir = kCurrentDirectoryString;
  }
  return FilePath(dir);
}
