Config...ubject(3pm)

💖 Config::Model::Role::WarpSubject 💖

okay bestie, sit down, hydrate, and let's talk about Config::Model::Role::WarpSubject — she's a Perl doc babe living in section 3pm of the User Contributed Perl Documentation, and she is so much cooler than her name suggests 🦋

---

✨ NAME ✨

Config::Model::Role::WarpSubject — common methods for a warped element 💅

✨ VERSION ✨

version 2.166 — yes, that's the one, no cap 👑

✨ SYNOPSIS ✨

the way you literally just do this:

package Config::Model::SomeStuff;
use Mouse;
with Config::Model::Role::WarpSubject

that's it. that's the whole vibe. 🎀

✨ DESCRIPTION ✨

so this role is giving warp master energy ⭐ — it lets a configuration element become a warp master, which basically means it's a parameter whose value can change the features of the configuration tree (by controlling a warped_node) or the features of various elements like leaf, hash …

and here's the tea 🍵 — this role is needy. it requires that you provide backup and allowed_warp_params methods. no methods, no warp. periodt.

✨ METHODS ✨

💫 merge_properties

Parameters: ( %arguments_to_merge )

she returns a hash containing a first level merge of the constructor arguments (those come back to you from the backup method, mwah) and the arguments to merge.

⚠️ lowkey important: the merge happens only at the first level — hash refs are merged there, but it is not a deep merge. scalars and arrays get clobbered. straight up obliterated. gone. 💀
