Config...Assert(3pm)

💖 Config...Assert(3pm) 💖

okay bestie, so this is a page from the User Contributed Perl Documentation section of the manual — it's Config...Assert(3pm), and no, the dots aren't a typo, that's just how the header renders the long name. we're keeping it cute anyway. 🎀

---

✨ NAME ✨

Config::Model::models::Itself::CommonElement::Assert — it's the Configuration class Itself::CommonElement::Assert. say that five times fast, I dare you. 💅

---

🌸 DESCRIPTION 🌸

These are the configuration classes used by Config::Model. that's the whole vibe. short, sweet, iconic. 👑

---

🦋 Elements 🦋

code 💻

Perl instructions that test the value, fr fr. $_ holds the value you're testing, and $self holds the value object.

use with care — that's straight from the source, not me being dramatic. $self is main character energy and main character energy can break things. 😭

Optional. Type: string. ✨

---

msg 💬

The warning message you show the user. "$_" contains the bad value — like, the value that failed the vibe check. example: "value $_ is bad".

Leave it blank or undef and you'll get a generated message instead, which is honestly the lowkey move if you can't be bothered. 💅

Optional. Type: string. 🌸

---

fix 🛠️

Perl instructions to fix the value. these instructions may be triggered by the user, so it's giving "help me help you".

• $_ contains the value to fix.
• $_ is stored as the new value once the instructions are done — so whatever you leave in $_ at the end? that's the new value. no takebacks. 👀
• $self contains the value object.

use with care on $self too, bestie. same energy as above. 🙈

Optional. Type: string. ⭐
