| 57 | ||
| 58 | Gruntmaster::Daemon::Runner::Interactive - Make an interactive verifier talk to the program | |
| 59 | ||
| 60 | =head1 SYNOPSIS | |
| 61 | ||
| 62 | use Gruntmaster::Daemon::Runner::Interactive; | |
| 0005d3ad | 63 | Gruntmaster::Daemon::Runner::Interactive::run(5, $meta); |

| 65 | =head1 DESCRIPTION | |
| 66 | ||
| 67 | B<WARNING: This runner is experimental!> | |
| 68 | ||
| 0005d3ad | 69 | 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. |
