Re: [Boost-users] commandline args

      That also gave me compilation errors:

..\Dependency\boost\boost/spirit/home/karma/generate.hpp(72) : error
C2664: 'boost::mpl::assertion_failed' : cannot convert parameter 1
from 'boost::mpl::failed ************(__thiscall
boost::spirit::karma::generate::error_invalid_expression::*
***********)(Expr)' to 'boost::mpl::assert<false>::type'

..\Dependency\boost\boost/spirit/home/karma/generate.hpp(76) : error
C2039: 'generate' : is not a member of
'boost::proto::exprns_::expr'

Below, please find a minimal example.
Thank you for your continued help!

Best,
Dee

Er, do this I mean (adding spacing to help clarify things for you to):
bk::generate(ostream_iterator<char>(cout),
 "Command line options not recognized:\n" <<
 ("  \"" << ba::string << '\"') % bk::eol
 ,vsUnrecog);
To describe it, it first prints out a string, then the % operator has
two part, the left side ('\"' << ba::string << '\"'), and the right
bk::eol, meaning that the left side is run for each element in a list
separated by returns.
Hi OvermindL1,
That is indeed exactly what I'm looking for, please also see my reply
to your previous message.
I want to enclose every item in the list with quotes and print them on
separate lines.
If that did not work, I am surprised, perhaps hartmut could see why,
he is the expert here.  :)
Try:
bk::generate(ostream_iterator<char>(cout),
 "Command line options not recognized:\n" <<
 ("  \"" << ba::string << '\"') >> *("\n  \"" << ba::string << '\"')
 ,vsUnrecog);
More verbose, but it should do the same thing as the top one, see if
it works, I am curious why the previous one did not know, I may have
to try it myself...
