Great toy. Kudos ;-)

Here's a more usable interact using Term::Readline. OFC, I named it interact2 just to avoid overriding your code ;-)

sub interact2 { my $self = shift; eval { require Term::ReadLine }; die "This method requires Term::ReadLine.\nError was: $@\n" if $@; # used for completion my @commands = map { $_->[0] } values %{$palias}; my $term = Term::ReadLine->new('Logo'); $term->Attribs->{attempted_completion_function} = sub { my $word = shift; $term->Attribs->{completion_word} = \@commands; return $term->completion_matches( $word, $term->Attribs->{list_completion_function} ); }; $term->Attribs->{attempted_completion_over} = sub {}; while () { my $cmd = $term->readline( 'logo> ' ); last if !defined $cmd; for ($cmd) { s/^\s+//; s/\s+$//; } next if $cmd !~ /\S/; if ( $cmd eq '?' || $cmd eq 'help' ) { $self->interactive_help(); } elsif ( $cmd =~ /^(?i:q(?:uit)?|bye|exit)$/ ) { last; } else { $self->interactive_command($cmd); # adding only valid commands would be nice # - possible if "interactive_command" returns some status $term->addhistory($cmd); } } return 0; # Exit interactive mode }

Obviously, it requires Term::ReadLine to basically work, and Term::ReadLine::Gnu to be able to use the custom completion method.
