我希望在打印options_description时,在描述允许的选项之前打印文本。类似的东西:
This program counts from 1 to 10. <--- this is what is missing
Generic options:
-h [ --help ] Produce help message.
-v [ --version ] Show program name/version banner and exit.
目前我手动添加:
if (vm.count("help")) {
cout << "options_description\n\n" << my_options_description << endl;
return 1;
}
是否可以将其直接存储在options_description对象中?

options_description
类用于描述选项,而不是程序。 Program_options库并非真正用于通用文档。
我想你可以滥用标签:
po::options_description options(
"This program counts from 1 to 10.\n\nGeneric options");
