Catman...pec_has(3pm)

💅 NAME 💅

Catmandu::Fix::Condition::marc_spec_has — bestie, this one tests whether a MARCspec actually references data. That's it, that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

# marc_spec_has(MARCspec)

unless marc_spec_has('LDR{/6=\a}{/7=\a|/7=\c|/7=\d|/7=\m}')
     set_field('type','Book')
end

---

🦋 DESCRIPTION 🦋

Okay so listen: this little icon evaluates the fixes wrapped around it only if the MARCspec actually references data. No data, no fix, no drama. 🙅♀️

It does the exact same thing as marc_has, except it's the glow-up version that uses MARCspec — A common MARC record path language. Same energy, fancier path syntax. 💅

For the full tea on path syntax, go read the docs at MARCspec - A common MARC record path language over at <http://marcspec.github.io/MARCspec/>. She's got the whole language documented, no cap. 📖✨

👑 METHODS 👑

marc_spec_has(MARCspec)

Lowkey the whole point: this evaluates to true when the MARCspec references data, and false when it doesn't. That's the vibe check. ⭐
