Sort::K...Register(3)

💖 Sort::K...Register(3) 💖

okay so bestie, this page is from User Contributed Perl Documentation, and it's all about Sort::Key::Register. the way this module just tells Sort::Key how to sort new data types? iconic. ✨

---

💖 NAME 💖

Sort::Key::Register — tell Sort::Key how to sort new data types. periodt. 💅

---

✨ SYNOPSIS ✨

okay so here's the group-chat screenshot of how you use it, no cap:

use Sort::Key::Register Person =>
    sub { $_->surname, $_->name },
    qw(string string);

use Sort::Key::Register 'Color::Component' => 'integer';

use Sort::Key::Register Color =>
    sub { $_->R, $_->G, $_->B },
    ('Color::Component') x 3;

---

🌸 DESCRIPTION 🌸

Sort::Key::Register allows one to register new data types with Sort::Key so that they can be sorted as natively supported ones. literally the glow-up those types needed. 💖

It works as a pragma module and doesn't export any function, all its functionality is provided via use. fr fr, it's giving:

use Sort::Key::Register ...

To avoid collisions between modules registering types with the same name, you should qualify them with the package name. bestie, do not skip this part:

use Sort::Key::Register 'MyPkg::foo' => sub { $_ }, '-int';

# or using __PACKAGE__:
use Sort::Key::Register __PACKAGE__, sub { $_ }, '-int';

🎀 USAGE 🎀

okay the two usable forms are giving:

• use Sort::Key::Register $name => \&multikeygen, @keytypes; — registers type $name. &multikeygen is the multi-key extraction function for the type, and @keytypes are the types of the extracted keys. 🫶
• use Sort::Key::Register $name => $keytype; — this use is useful for simple types that are sorted as another type already registered, maybe changing the direction of the sort (ascending or descending). 🌈
