Promise...nyEvent(3)

💖 Promises::Deferred::AnyEvent 💖

okay so bestie, welcome to Promises::Deferred::AnyEvent, a page straight out of the User Contributed Perl Documentation collection. it's giving "promises but make it async" and honestly? we're obsessed. 🦋

---

✨ NAME ✨

Promises::Deferred::AnyEvent — an implementation of Promises in Perl. yes that's the whole name, no notes, it ate. 💅

---

🌸 VERSION 🌸

version 1.05 ✨ (she's grown, she's thriving)

---

🎀 SYNOPSIS 🎀

use Promises backend => ['AnyEvent'], qw[ deferred collect ];

# ... everything else is the same

lowkey the "everything else is the same" is the most iconic line in the whole file. main character energy fr fr. 👑

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: the "Promise/A+" spec is very strongly opinionated about the fact that the callbacks you hand over to then should run asynchronously — meaning in the next turn of the event loop, not right this second like some impatient little gremlin. 🙈 and this module? this module is the one that makes that happen, by using the AnyEvent module to do the actual async-ing. she's the backbone. the behind-the-scenes queen. 👑

now here's the part where module authors need to chill: if you're writing a module, you should not be out here caring which event loop is gonna get used. that's not your business bestie, that's a runtime decision. just use the Promises module directly and let the universe handle it:

package MyClass;

use Promises qw(deferred collect);

see? no event loop opinions. so peaceful. so unbothered. 🧘

meanwhile, the end users of the module — the ones actually running the app — they get to pick the backend themselves at the start of the application, like they're choosing an outfit for the day:

use Promises -backend => ['AnyEvent'];
use MyClass;

and that's it, that's the whole vibe check. the user decides, the module doesn't have to know, everybody wins. 💖
