Reply To: 提高部分测试问题

[左趋趋]

我写了一个新的命令行parser部分，测起来就比较方便了。

    while (parsePos < argc)
    {
        std::string arg = std::string(argv[parsePos]);
        if (arg == "-r")
        {
            if (parsePos + 1 >= argc)
            {
                std::cerr << "-r option error" << std::endl;
                std::cerr << "Usage: " << argv[0] << " -r angle [-a axisX axisy axisZ] [filename.png]" << std::endl;
                exit(-1);
            }
            angle = std::stof(argv[parsePos + 1]);
            parsePos += 2;
        }
        else if (arg == "-a")
        {
            if (parsePos + 3 >= argc)
            {
                std::cerr << "-a option error" << std::endl;
                std::cerr << "Usage: " << argv[0] << " -r angle [-a axisX axisy axisZ] [filename.png]" << std::endl;
                exit(-1);
            }
            raxis.x() = std::stof(argv[parsePos + 1]);
            raxis.y() = std::stof(argv[parsePos + 2]);
            raxis.z() = std::stof(argv[parsePos + 3]);
            parsePos += 4;
        }
        else if (arg.rfind(".png") == arg.size() - 4)
        {
            command_line = true;
            filename = arg;
            parsePos += 1;
        }
        else
        {
            std::cerr << "Invalid option or filename: " << arg << std::endl;
            std::cerr << "Usage: " << argv[0] << " -r angle [-a axisX axisy axisZ] [filename.png]" << std::endl;
            exit(-1);
        }
    }
