Catman...:rename(3pm)

✨ NAME ✨

Catmandu::Fix::rename — the fix that renames your fields with a regex 💅

Okay bestie, so this is Catman...:rename(3pm) from the User Contributed Perl Documentation, and it's giving glow-up for your field names. Lowkey iconic.

---

🎀 SYNOPSIS 🎀

Like, here's the vibe. You feed it a field, a regex to match, and what to swap it for:

# dotted => {'ns.foo' => 'val', list => {'ns.bar' => 'val'}}
rename(dotted, '\.', '-')
# dotted => {'ns-foo' => 'val', list => {'ns-bar' => 'val'}}

So before, your field was all 'ns.foo' and 'ns.bar' (dotted, periodt 💀), and after running the fix it's 'ns-foo' and 'ns-bar' — the dots got swapped for dashes, no cap. The way that regex just does that? Obsessed. 🦋
