Catman...id_issn(3pm)

✨ NAME ✨

okay so bestie, meet Catmandu::Fix::Condition::is_valid_issn — it's a condition that checks whether ISSN numbers are actually valid, no cap. 💖

(it lives in the Catman...id_issn(3pm) page, iykyk — the terminal just couldn't fit the whole glow-up of a name. 🎀)

🌸 SYNOPSIS 🌸

the vibe is literally just: if the ISSN is valid, do one thing, otherwise do the other thing. iconic branching behavior:

if is_valid_issn(issn_field)
  ...
else
  ...
end

issn_field is your placeholder for whatever field you're checking, and the ... bits are all yours to fill in. main character energy. 👑
