4781	Boost Program Options 'arg' text could be editiable.	robertmassaioli@…	Vladimir Prus	"I have a minor feature request and that is that when I write out a program option that has an argument it comes out, for example, like this:

{{{
  -m [ --log-file ] arg (=<none>)         set log file.
}}}

But that 'arg' does not look nice to me; I would rather that it read: 

{{{
  -m [ --log-file ] <filename> (=<none>)         set log file.
}}}

And I would like to be able to set that somehow in the po::value setup. I also checked to see if you could do this already and it seems as though you cannot in the boost::program_options source code itself starting on line 67 of value_semantic.cpp there is the following lines:

{{{#!cpp
BOOST_PROGRAM_OPTIONS_DECL std::string arg(""arg"");

std::string
untyped_value::name() const
{
    return arg;
}
}}}

So since 'arg' seems to be set in stone I do not think that it is possible to do this yet. I would really like to know if you think this is a good idea or not. Thanks."	Feature Requests	closed	To Be Determined	program_options	Boost 1.44.0	Problem	fixed	arg program_options
