61 | =head1 NAME | |
62 | ||
63 | Gruntmaster::Daemon::Runner::Interactive - Make an interactive verifier talk to the program | |
64 | ||
65 | =head1 SYNOPSIS | |
66 | ||
67 | use Gruntmaster::Daemon::Runner::Interactive; | |
0005d3ad | 68 | Gruntmaster::Daemon::Runner::Interactive::run(5, $meta); |

70 | =head1 DESCRIPTION | |
71 | ||
72 | B<WARNING: This runner is experimental!> | |
73 | ||
0005d3ad | 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. |
