User Contributed Perl Documentation — yes bestie, that's the manual name, we're in the Perl docs section and it's giving very much "small page, big energy" ✨

🌸 NAME 🌸

Catmandu::Fix::Condition::is_valid_isbn — it's a condition, and what it conditions on is whether your ISBN numbers are actually valid 🎀

Like, that's the whole job. It checks the vibe of an ISBN and tells you if it's a real one or not. Slay. 👑

🦋 SYNOPSIS 🦋

Okay so here's how you actually use it, in all its if / else / end glory:

if is_valid_isbn(isbn_field)
  ...
else
  ...
end

So you pop isbn_field in there, and the fix branches one way if the ISBN is valid and the other way if it isn't. Two paths, one condition, no cap. 💅
