Sub::Ha...assTiny(3)

✨ Sub::HandlesVia::Manual::WithClassTiny ✨

okay bestie, so this is a page from the User Contributed Perl Documentation — it's the manual for Sub::HandlesVia::Manual::WithClassTiny, aka "how to use Sub::HandlesVia when your class is built with Class::Tiny". it's giving very specific but very useful, iykyk. 💅

---

🌸 NAME 🌸

Sub::HandlesVia::Manual::WithClassTiny — using Sub::HandlesVia with Class::Tiny. periodt.

---

🎀 SYNOPSIS 🎀

look at this absolute icon of a setup:

package Kitchen;

use Class::Tiny {
  foods  => sub { [] },
  drinks => sub { [ 'water' ] },
};

use Sub::HandlesVia::Declare 'foods', Array => (
  all_foods  => 'all',
  add_food   => 'push',
);

use Sub::HandlesVia::Declare 'drinks', Array => (
  all_drinks => 'all',
  add_drink  => 'push',
);

like. the vibes. a Kitchen with foods and drinks and methods that just... show up. obsessed. 🍓

💖 MANUAL 💖

so Sub::HandlesVia lets you delegate methods from your class straight to the values of your objects' attributes. it's the group project where nobody has to do anything because the delegation handles it. no cap.

conceptually, it lets you define $object->push_number($n) as a shortcut for $object->numbers->push($n) — except that $object->numbers is an arrayref, so it literally does not have methods you can call on it like push. tragic, honestly. that's the whole problem this module fixes. 😭

🦋 Which Methods Can Be Delegated To? 🦋

the second parameter (that's Array in the synopsis, bestie) tells you which library of methods should be available. valid values include:

• Array
• Blessed
• Bool
• Code
• Counter
• Enum
• Hash
• Number
• Scalar
• String

you can also hand it an arrayref of them, though lowkey a lot of these options are conceptually contradictory, so maybe don't go feral:

use Sub::HandlesVia::Declare 'num', [ 'Number', 'Scalar' ] => (
  ...,
);

🌈 Run-Time Delegation 🌈

instead of Sub::HandlesVia::Declare, which operates at compile time, you can use the delegations function at run time. which one you pick is largely down to style and personal preference — main character energy either way. 💅

package Kitchen;

use Class::Tiny {
  foods  => sub { [] },
  drinks => sub { [ 'water' ] },
};

use Sub::HandlesVia qw( delegations );

delegations(
  attribute    => 'foods',
  handles_via  => 'Array',
  handles      => {
    all_foods    => 'all',
    add_food     => 'push',
  },
);

delegations(
  attribute    => 'drinks',
  handles_via  => 'Array',
  handles      => {
    all_drinks   => 'all',
    add_drink    => 'push',
  },
);

and that's the whole page!! this one's from perl v5.42.0, dated 2026-02-11, and it lives under the manual name Sub::Ha...assTiny(3) in the User Contributed Perl Documentation. slay, go delegate some methods, and remember: the attribute doesn't have methods, but you do now. 💅✨
