Catman..._match(3pm)

💖 NAME 💖

Catmandu::Fix::Condition::marc_all_match — okay bestie, this is the little Fix condition that checks if a MARC (sub)field matches a value. That's the whole vibe. It's a Perl thing, from the User Contributed Perl Documentation, and it is lowkey a bop. ✨

🌸 SYNOPSIS 🌸

# marc_all_match(MARC_PATH,REGEX)

# Match when 245 contains the value "My funny title"
if marc_all_match('245','My funny title')
     add_field('my.funny.title','true')
end

# Match when 245a contains the value "My funny title"
if marc_all_match('245a','My funny title')
     add_field('my.funny.title','true')
end

# Match when all 650 fields contain digits
if marc_all_match('650','[0-9]')
  add_field('has_digits','true')
end

Look at those three little glow-ups. First one hits a whole field, second one hits a subfield, third one does the all of them thing. Slay. 💅

🎀 DESCRIPTION 🎀

So here's the tea, bestie: this condition evaluates the enclosing fixes only if the MARC (sub)field matches a regular expression. No match, no fixes. It's giving bouncer at the club. 🚪✨

And when the MARC field is a repeated field — the source page literally spells it fiels, and honestly? we stan a typo — then all the MARC fields have to match that regular expression. Every single one. Not most of them. Not the cute ones. All of them. Periodt. 👑

🦋 METHODS 🦋

🌟 marc_all_match(MARC_PATH, REGEX)

Evaluates to true when all MARC_PATH values matches the REGEX, false otherwise.

That's it, that's the method. Short, sweet, does exactly what it says on the tin. 🫶

💜 SEE ALSO 💜

• Catmandu::Fix::Condition::marc_any_match — the chaotic sibling. If this one is "all of them or nothing", that one is "any single one and we're good." Pick your fighter. 🥊
