63 Gruntmaster::Daemon::Runner::Interactive - Make an interactive verifier talk to the program

67 use Gruntmaster::Daemon::Runner::Interactive;
68 Gruntmaster::Daemon::Runner::Interactive::run(5, $meta);

70 =head1 DESCRIPTION
71
72 B<WARNING: This runner is experimental!>
73
74 Gruntmaster::Daemon::Runner::Interactive is a runner which runs the program and an interactive verifier in parallel, connecting each program's STDIN to the other's STDOUT. The verifier, C<< $meta->{files}{ver} >>, should return nonzero if the program gives an incorrect answer, or print the test score to fd 4 then return 0 if the answer is correct.
