Hi, I am getting boost::io::too_many_args exceptions for the following line.

cout << format(" %1% %3% \n") % 1 % 2 % 3 % 4 % 5;

but not for this one

cout << format(" %1% %5% \n") % 1 % 2 % 3 % 4 % 5;

If the last argument is used in the format, I do not get the exception.

Is this a bug?

Thanks.

this is by design, and mentionned in the documentation : """ The only constraint is that it expects exactly /P/ arguments, /P/ being the maximum argument number used in the format string. (e.g., for "%1$d %10$d", /P/ is 10 ). Supplying more, or less, than /P/ arguments raises an exception. (unless it was set otherwise, see exceptions http://www.boost.org/libs/format/doc/format.html#exceptions) """ regards, -- Samuel
