Catman...:expand(3pm)

💅 NAME 💅

Catmandu::Fix::expand — bestie, this one takes a flat hash and turns it back into nested data, using the TT2 dot convention. That's the whole vibe. No cap. ✨

---

🦋 SYNOPSIS 🦋

Okay so here's the whole flex, look:

# collapse the data into a flat hash
collapse()

# expand again to the nested original
expand()

# optionally provide a path separator
collapse(sep: '/')
expand(sep: '/')

See how it goes? You collapse() it down flat, then expand() it right back to the nested original like nothing ever happened. Glow-up AND glow-down. 🫶 And if you're feeling fancy, you can hand it a path separator with sep: — like sep: '/' — on either one. Iconic behavior fr fr. 🎀
