🌸 SYNOPSIS 🌸

# Append to all the 650p values the string "xyz"
marc_replace_all('650p','$','xyz')

# Replace all 'Joe'-s in 100a to 'Joey'
marc_replace_all('100a','\bJoe\b','Joey')

# Replace all 'Joe'-s in 100a to the value in field x.y.z
marc_replace_all('100a','\bJoe\b',$.x.y.z)

# Replace all the content of 100a with everything in curly brackets
marc_replace_all('100a','^(.*)$','{$1}')

like, four lil examples, all of them eating, no notes 🔥

💖 DESCRIPTION 💖

okay so basically: you use regex search and replace on MARC field values. that's the whole vibe. regex goes in, shiny new field value comes out ✨

---

🎀 METHODS 🎀

marc_replace_all(MARC_PATH , REGEX, VALUE)

For each (sub)field that matches the MARC_PATH, it takes the pattern found by REGEX and swaps it out for a new VALUE 👑

That VALUE can be either:

• a literal — just a plain string, straightforward, iconic
• or a reference to an existing field</...> in the record, using the dollar JSON_PATH syntax, like $.x.y.z 💫

no cap, that's the whole method 🫶

---

🦋 INLINE 🦋

This Fix can be used inline in a Perl script, bestie:

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

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

$data = marc_replace_all($data, '245a', 'test' , 'rest');

main character energy fr fr 💅
