#5046 closed Bugs (fixed)

directing tuples to ostream does not work as expected

Reported by: anonymous Owned by: Steven Watanabe
Milestone: To Be Determined Component: tuple
Version: Boost 1.45.0 Severity: Problem
Keywords: tuple output formatting Cc: meesters@…

Description

Assuming 'out' is a std::ostream the following code produces wrong output: 

out <<  boost::tuples::set_open('[')
    <<  boost::tuples::set_close(']')
    <<  boost::tuples::set_delimiter(',')
    <<  std::setw(21) << std::right << some_boost_tuple;

Instead of being within a field of 21 spaces, the tuple is appended to those spaces.

When fixing the bug - is it possible to also account for double precision settings by '<< std::std::setprecision(integer)'? That would be really helpful if dealing with tuples containing doubles.

TIA Christian Meesters

Doesn't std::setprecision work now?
