50 | ||
51 | Gruntmaster::Daemon::Runner::Interactive - Make an interactive verifier talk to the program | |
52 | ||
53 | =head1 SYNOPSIS | |
54 | ||
55 | use Gruntmaster::Daemon::Runner::Interactive; | |
56 | Gruntmaster::Daemon::Runner::Interactive->run(5, $meta); | |
57 | ||
58 | =head1 DESCRIPTION | |
59 | ||
60 | B<WARNING: This runner is experimental!> | |
61 | ||
62 | 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}{int} >>, should return nonzero if the program gives an incorrect answer, and print the test score to fd 4 then return 0 if the answer is correct. | |
