$ cat /tmp/1.pl #!/usr/bin/perl use warnings; use strict; use IO::Prompter 'prompt'; my %actions = ( display => sub { print_table(); }, learn => sub { learn_message(); }, quit => sub { exit; }, ); while (my $mode = prompt 'What to do now?', -menu => [ keys %actions ] +) { compute_scores(); $actions{$mode}->(); } $ perl /tmp/1.pl What to do now? a. quit b. learn c. display Enter [a-c]:
How it works:
  • What to do now? a. quit b. learn c. display
  • I type "a" and get "p"
  • I get surprised and press Enter
  • Enter [a-c]:
  • I type some other buttons (no matter if they are "abc" or something completely different)
  • Enter [a-c]: rompt
  • I press Enter again
  • Enter [a-c]:
  • Prompt remains silent forever
