Catman...as_many(3pm)

💖 NAME 💖

Catmandu::Fix::Condition::marc_has_many — bestie, this is the vibe check that asks: does this MARC record have more than one (sub)field? That's it. That's the whole job. ✨

(also hi, you found this in section 3pm of the User Contributed Perl Documentation, aka the perl module corner of the manual, welcome 🫶)

🌸 SYNOPSIS 🌸

# marc_has_many(MARC_PATH)

if marc_has_many('245')
     add_field('error.$append','more than one 245!')
end

okay so like, if the 245 shows up more than once, you get yourself a lil error field. iconic behavior honestly 💅

🦋 DESCRIPTION 🦋

So here's the tea: marc_has_many only lets the enclosing fixes run when the MARC record has more than one (sub)field. Otherwise? Nothing happens. The fixes just sit there. Respectfully. 🙈

---

🎀 METHODS 🎀

⭐ marc_has_many(MARC_PATH)

Evaluates to true when the MARC has more than one (sub)field, and false otherwise. No in-between, no situationship, just true or false. periodt. 👑
