Catman...x::uniq(3pm)

✨ NAME ✨

okay bestie, welcome to Catmandu::Fix::uniq 💖 — it's a Catmandu::Fix page from the User Contributed Perl Documentation, section 3pm, and it does exactly one thing and does it flawlessly:

• Catmandu::Fix::uniq — strip duplicate values from an array 🧹✨

like… that's it. that's the whole job. it takes your array, it looks at all the lil values, and it goes "not today, twin" to every repeat. iconic behaviour honestly 🎀

---

🌸 SYNOPSIS 🌸

here's the whole vibe in one little block, no cap 🦋

# {tags => ["foo", "bar", "bar", "foo"]}
uniq(tags)
# {tags => ["foo", "bar"]}

so you walk in with tags being ["foo", "bar", "bar", "foo"] — kinda messy, kinda giving "i said it twice bc i meant it" 😭 — and you walk out with ["foo", "bar"]. the duplicates got un-alived (affectionately), the survivors kept their order, and the array is now clean. slay. 💅

lowkey the way this works is you call uniq(tags) on the field name and it rewrites that same field in place, so your fix file stays cute and tidy. periodt.
