Hash::...::Lower(3pm)

🦋 NAME 🦋

okay so bestie, welcome to Hash::Case::Lower — it's literally a hash with enforced lower cased keys. that's the whole vibe. no cap.

---

✨ INHERITANCE ✨

it's giving family tree, and the lineage is iconic:

• Hash::Case::Lower
  • is a Hash::Case
  • is a Tie::StdHash

like, it knows exactly who it is and where it came from. main character energy fr fr 💅

---

🎀 SYNOPSIS 🎀

here's the whole thing in action, copy it exactly or don't @ me:

use Hash::Case::Lower;
tie my(%lchash), 'Hash::Case::Lower';
$lchash{StraNGeKeY} = 3;
print keys %lchash;  # strangekey

see how StraNGeKeY walked in all chaotic and left as strangekey? that's not a glitch, that's the feature 💖

🌸 DESCRIPTION 🌸

okay so Hash::Case::Lower extends Hash::Case, which is the whole module family that lets you play various trics with hash keys (yes, "trics" — that's how the original spells it, we don't fix, we respect 🫶).

in this implementation, the fake hash is case insensitive, and the keys are stored in lower-case. that's it, that's the whole deal. every key gets the lowercase treatment whether it asked for it or not. slay.

also it Extends DESCRIPTION in Hash::Case. so if you want the full lore, that's where to look 👑

⭐ METHODS ⭐

Extends METHODS in Hash::Case. we're building on the base class, bestie — it's a whole ecosystem.

💜 Constructors

Extends Constructors in Hash::Case.

• tie %hash, 'Hash::Case::Lower', [$values,] %options — defines %hash to have only lower-cased keys. the hash gets initialized with $values, which you can hand over as an ARRAY (with key-value PAIRS) or as a HASH. rn there are literally no %options defined — zero, none, the options list is empty and honestly? respect. improves base, see Constructors in Hash::Case

🧚 Hidden object access

Extends Hidden object access in Hash::Case. these are the backstage-pass methods 👑

• $obj->addHashData(\%data) — Inherited, see Hidden object access in Hash::Case
• $obj->addPairs(@pairs) — Inherited, see Hidden object access in Hash::Case
• $obj->setHash(\%data) — Inherited, see Hidden object access in Hash::Case
