I've been using program_options quite happily and successfully for a short while now and would like to take this opportunity to express my gratitude.
Is there a way to extract postional args from config file, though? The headers seem to indicate that it's possible include_positional flag, but I haven't been able to find something workable in the documentation or mailing lists.
It's not possible, as I never saw a config file with positional options. The 'include_positional' you mention is defined like this: /** Controls if the 'collect_unregistered' function should include positional options, or not. */ enum collect_unrecognized_mode { include_positional, exclude_positional }; so it only applies to collect_unregistered function. As config file parser will never return positional options, 'include_positional' is of no use. Does this clarifies things? - Volodya
