Re: Passing value to a Perl module

[karlgoethebier]

Deluxe edition:

Fool.pm

package Fool {
    use strict;
    use warnings;
    use Class::Tiny qw(hello);
    use feature qw(say);
    say __PACKAGE__;
    1;
}

run.pl

#!/usr/bin/env perl

use strict;
use warnings;
use feature qw(say);
use Fool;

my $president = Fool->new( { hello => q(I'm a very stable genius!) } )
+;

say $0;
say __PACKAGE__;
say $president->hello();

__END__

Please see Class::Tiny for further variations.

Update: Fixed link to wrong module.

Update 2: A fellow monk asked for some more flexibility:

package President {
    use strict;
    use warnings;
    use Class::Tiny qw(name hello);
    use feature qw(say);
    say __PACKAGE__;
    1;
}

package Fool {
    use strict;
    use warnings;
    use parent qw (President);
    use Class::Tiny qw( steve ivanka melania barron );
    use feature qw (say);
    say __PACKAGE__;
    sub old     { shift->SUPER::new(@_) }
    sub twitter { shift->SUPER::hello(@_) }
    1;
}

#!/usr/bin/env perl

use strict;
use warnings;
use feature qw(say);
use Fool;

my $president = Fool->old(
    {
        name    => q(Donald),
        hello   => q(I'm a very stable genius!),
        steve   => q(fired),
        melania => q(bored),
        ivanka  => q(dumb as bread),
        barron  => q(poor boy),
    }
);

say $0;
say __PACKAGE__;

say q(I'm ),         $president->name;
say q(Steve is ),    $president->steve;
say q(Melania is ),  $president->melania;
say q(Ivanka is ),   $president->ivanka;
say q(Barron is a ), $president->barron;
say $president->twitter;
say $president->twitter(q(Too many shithole countries in the world!));
say $president->twitter(q(I think i'll go to Mar-a-Lago));

__END__
