Config...nction(3pm)

💖 Config::Model::Role::ComputeFunction 💖

okay bestie so this is a Perl thing, a role (that's like a lil mixin, iykyk) — it's Config::Model::Role::ComputeFunction and honestly? it's giving "compute &index or &element functions". 🎀

it's version 2.166 btw, slay.

---

✨ SYNOPSIS ✨

$value->eval_function('index');
$value->eval_function('element');

$value->eval_function('index','-');
$value->eval_function('index','- -');
$value->eval_function('index','-3');

$value->compute_string('&element(-)')
$value->compute_string('&index(- -)');

like, look at her go. 💅

---

🌸 DESCRIPTION 🌸

so basically this role exists so a value object can go get the index or the element name of $self… or of a node above it (going up, like climbing the family tree, no cap). 🦋

---

👑 METHODS 👑

⭐ eval_function

bestie this one goes and retrieves the index or the element name for you. the params are:

( function_name , [ up  ])

• function_name — literally just "element" or "index". pick your fighter. 🌈
• up — optional! it tells you how many levels to go up before grabbing that index or element name. each "-" is equivalent to a call to "parent|Config::Model::Node/parent". you can do repeated dashes (like "-", "- -", …) or one dash with a multiplier (like "-", "-2", …). white spaces? ignored, she doesn't even see them. 💀

🧚 compute_string

this one does a similar thing to "eval_function" except it works off a string, and the function names get extracted from inside it. iconic honestly.

E.g. "compute_string('&element(-)')" calls "eval_function('element','-')" 🫶
