I need to supply to my app a config file with following entries:
item1 = 123 item2 = 435 item3 = 345 ... itemN = 562
where N is not known in advance, so there is no way to register such options. The only way to deal with them is to pass them as unregistered options and then use collect_unrecognized(). But then dealing with a vector<string> is not quit convenient. My suggestion is to add an a storeUnregistered flag to the store() function which will be false by default, but if set to true, will store all unregistered options with their values as strings. It will be possible then to check whether an item was provided like this: vm.count("item1") and cast its value like this: vm["item1"].as<int>() . Or is there already a good way to do what I need?
While that seems plausible, it allows for open-ended collection of options. I'd rather see a callback-based filter or the ability to register a regex to recognize acceptable options. ___ Rob
