Term::Visual does this. It redirects STDERR messages into its terminal
window, first giving them some color.
### Redirect STDERR into the terminal buffer.
use Symbol qw(gensym);
# Pipe STDERR to a readable handle.
my $read_stderr = gensym();
pipe($read_stderr, STDERR) or do
{ open STDERR, ">&=2";
die "can't pipe STDERR: $!";
};
$heap->{stderr_reader} = POE::Wheel::ReadWrite->new
( Handle => $read_stderr,
Filter => POE::Filter::Line->new(),
Driver => POE::Driver::SysRW->new(),
InputEvent => "got_stderr",
);
And you get "got_stderr" events when something occurs on STDERR.
