Non-option arguments about cargs HOT 3 CLOSED

Hi @markmaker , I have been thinking for a while now to provide an explicit API for that. The non-option arguments will always be moved to the end, so you can just access them using their index starting from the context index.

For now you can simply do it like this (This has to happen after the option loop which moves the context.index to the beginning of the non option parameters):

 for (param_index = context.index; param_index < argc; ++param_index) {
   printf("additional parameter: %s\n", argv[param_index]);
 }

I have added the example to the README.md and the example in the demo folder as well. Does that help you?

Also, the parameters will stay in order as they were supplied. So if you want to access them by index:

int non_option_parameter_count = argc - context.index;
if (non_option_parameter_count == 2) {
  const char *first_non_option_parameter = argv[context.index]; // in your case src
  const char *second_non_option_parameter = argv[context.index + 1]; // in your case dst
}

Perfect, thanks!
