How to read string with spaces, until a '\r'?

I want to read a long string, and split it into smaller ones, where each new row of the big string is an entry for the smaller ones. However, I only want it to break at '\r', and not at spaces. This is a sample code of what I'm doing right now:

std::vector<std::string> m_list;
std::ifstream input("data.txt");
std::string str;
std::getline(input, str);
std::istringstream iss(str);
std::string temp;
while (iss >> temp)
{
    m_list.push_back(temp);
}

However, this code breaks the string upon encountering spaces, as well.

You where definitely on the right path, you actually just need to skip the direct string stream operation. This should work fine:

    std::vector<std::string> m_list;
    std::ifstream input("data.txt");
    std::string str;        
    
    while (std::getline(input, str, '\r'))
    {
        m_list.push_back(str);
    }
