Dancer2...sConfig(3)

📦
version 2.2.1 · 3 versions
, in fedora 44

✨ NAME ✨

Dancer2::Core::Role::HasConfig — it's the role that holds all the config of a Dancer2 App 💖 (you'll also see it filed under Dancer2...sConfig(3) in the User Contributed Perl Documentation, iykyk)

🎀 VERSION 🎀

version 2.2.1 — fresh, iconic, current ✨

💅 DESCRIPTION 💅

okay so bestie, listen. This role hands you a config attribute, and that's literally the thing you use to read the configuration. 🫶

Here's the little plot twist: the very first time you touch it, it calls a method called _build_config(). And that method? it has to be implemented by the class that's using this role — no skipping, no shortcuts, it's giving main character responsibility. 😤

What should _build_config() give back? The whole config — the entire thing, the full vibe — the one that's been created by running one or more ConfigReader packages. All of them. Together. That's the assignment. 💖

It also gives you a setting() method, and that one is supposed to be used by externals — so things outside your app — to read and write config entries. Yes, read and write. She does both. 👑

🌸 ATTRIBUTES 🌸

config

Returns the whole configuration. That's it, that's the whole job, and she ate. 💅

🦋 METHODS 🦋

settings

Alias for config. Literally equivalent to <<$object->config>>. Same energy, different name. 🎀

setting

Get or set an element from the configuration. Read it, write it, whatever you need — she's flexible like that. ✨

has_setting

Verifies that a key exists in the configuration. The vibe check for your keys — does it exist or not, bestie, we're about to find out. 👀
