Debug(3pm)

💖 B::Debug 💖

okay bestie, so this is B::Debug, a Perl module that literally walks the Perl syntax tree and prints debug info about ops 🦋 it's giving backstage tour of your code's whole vibe, no cap.

It's a Debug(3pm) manual page, and it's here to make your bestie-level Perl internals knowledge go from zero to iconic.

---

✨ SYNOPSIS ✨

perl -MO=Debug foo.pl
perl -MO=Debug,-exec foo.pl

yeah that's it, that's the whole thing 💅 you just slap -MO=Debug on your perl invocation and it does the thing.

---

🌸 DESCRIPTION 🌸

okay so the actual docs here are short and sweet: go read ext/B/README and also the newer B::Concise 👑 those are the real main characters. This page is lowkey just pointing you at them.

---

🎀 OPTIONS 🎀

• -exec — with this option, the tree gets walked in execute order 💫 without it, you get basic order. that's the whole tea.
