💖 Catmandu::Fix::marc_decode_dollar_subfields 💖

okay bestie, so this one is Catmandu::Fix::marc_decode_dollar_subfields, a Perl module from the User Contributed Perl Documentation corner of the universe, and it's literally the fix you need when your MARC data is doing too much. 🎀

---

✨ NAME ✨

Catmandu::Fix::marc_decode_dollar_subfields — decode double encoded dollar subfields

like... the name is the whole plot. no notes. 👑

---

🌸 SYNOPSIS 🌸

marc_decode_dollar_subfields()

that's it. that's the call. she's simple, she's elegant, she's iconic. 💅

---

🦋 DESCRIPTION 🦋

okay so here's the tea. 🍓 In some environments, MARC subfields can contain data values that can be interpreted as subfields itself. yes, subfields inside subfields. it's giving inception, it's giving nesting doll energy, and honestly? not it. 😭

E.g. when the 245-$a subfield contains the data:

My Title $h subsubfield

then the $h = subsubfield will not be accessible with normal MARC processing tools. like, it's right there, hiding in plain sight, and your regular tools just cannot see it. the audacity. 💀

Use the 'marc_decode_dollar_subfields()' fix to re-evaluate all the MARC subfields for these hidden data. it goes in, finds the sneaky little encoded dollar subfields, and gives them their main character moment. ✨

---

💅 METHODS 💅

🌈 marc_decode_dollar_subfields()

Decode double encoded dollar subfields into real MARC subfields.

fr fr, that's the job. double encoded in, real MARC subfields out. no cap. 🫶

---

⭐ INLINE ⭐

This Fix can be used inline in a Perl script, which is lowkey the moment you've been waiting for:

use Catmandu::Fix::marc_decode_dollar_subfields as => 'marc_decode_dollar_subfields';

my $data = { record => [...] };

$data = marc_decode_dollar_subfields($data);

see how clean that is? as => 'marc_decode_dollar_subfields', then boom, you just call it on your $data and the record array does its thing. ate and left no crumbs. 🔥
