🦋 Catman...dition(3pm) 💅

okay so bestie, welcome to the Catman...dition(3pm) page — it lives in section 3pm of the User Contributed Perl Documentation, and it's literally the blueprint for every single conditional in Catmandu. no cap. let's get into it 🫶

---

✨ NAME ✨

Catmandu::Fix::Condition — the Role for all Catmandu::Fix conditionals. it's giving "everyone who wants to be a condition has to sign this contract" 📝

---

🌸 SYNOPSIS 🌸

the whole vibe in code form, bestie:

if <Catmandu::Fix::Condition instance>
        <pass_fixes>
else
        <fail_fixes>
end

like. it's an if/else. but make it Catmandu. iconic. 👑

---

🎀 DESCRIPTION 🎀

so here's the tea ☕ — every Catmandu::Fix condition out there needs to implement Catmandu::Fix::Condition. that's not optional, that's the rule, periodt.

this class is a subclass of Catmandu::Fix::Base, and what it brings to the group chat is two little lists:

• a list of fixes that get executed when the conditional matches — that's your pass_fixes 🎉
• and a conditional that needs to be executed when the conditional fails — that's your fail_fixes 😭

ngl, that second sentence is worded a liiittle cursed in the original, but the energy is: pass fixes fire on a match, fail fixes fire on a no-match. you got this 💖

and plot twist — conditions can be used as inline fixes too! not just in the if/else block. look:

use Catmandu::Fix::Condition::exists as => 'has_field';

my $item = { foo => { bar => 1 } };

has_field($item, 'foo.bar');    # true
has_field($item, 'doz');        # false

see how foo.bar is true because it exists, and doz is false because... it does not? slay. that's the whole bit. 🧚

---

💖 EXAMPLES 💖

Catmandu core comes with these conditions, and honestly? the lineup ate. here's the full roster, no skips, no cuts:

• all_equal
• all_match
• any_equal
• any_match
• exists
• greater_than
• in
• is_array
• is_false
• is_null
• is_number
• is_object
• is_string
• is_true
• less_than

sixteen of them. a whole squad. 🌈⭐

and that's the page!! 🎀 this lil masterpiece comes to you from perl v5.40.1, dated 2026-01-24, and it's filed under that same Catman...dition(3pm) energy. go write a conditional, bestie, you're the main character now 💅✨
