Re: [Boost-users] [Program Options] Requiring command-line options

So this is not in the documentation? Could you add a ticket in track to fix the documentation? Best, Dee On Thu, Jun 3, 2010 at 9:09 PM, immanuel litzroth wrote:

Heya!  I just thinking about switching from simpleOpt to BoostPO for command line handling, mainly because of its support of configuration files.  This may be a stupid question, but I haven't seen anything about making a command line parameter *required*.  You'd think this is a pretty common thing, but I didn't see any mention of it in the tutorials or anything.  I guess I could just make certain parameters default -1/NULL or something, and then test at the end if they're still equal to that, but that seems a bit ugly. Is there built in support (a flag in the "add_options" function or something) for making certain parameters required?

Thanks a lot!
