It would be great to implement support for open-end options, something like that:
item_1 = 23 item_2 = 45 ... item_N = 465
The idea is to to be able to provide following input:
configOptions.add_options() ("item_", value<int>(), "items");
now if add_options() sees a key that ends with a "_" it accepts all options with keys that start with item_, no matter what comes after it, and treat all of them as int .
I think that's really odd, though I understand that you want something to allow a great number of options without defining them ahead of time. My first thought was a command line delimiter to introduce a list of such options: ... --foo 1=23 2=45 ... N=465 You'd specify "foo" as the delimiter and PO would then parse the remaining values into pairs to populate a map. Since the set of name/value pairs is open ended, they would always go last on the command line. Of course, you could also specify a delimiter to signal the end of the pairs. (If you want validation that the option names match a pattern, you can add that, too.) To avoid the name/value pairs, the following could be used to populate a vector: ... --foo 23 45 ... 465 ___ Rob
