DLOPEN-NOTES.PY(1)

✨ dlopen-notes.py ✨

okay bestie, welcome to dlopen-notes.py — it's a little script from the Generated Python Manual, and it's genuinely one of my faves, no cap. 💖

🌸 NAME 🌸

dlopen-notes.py — the girl who reads your .note.dlopen notes and tells you what's in them 🕵️♀️✨

---

🎀 SYNOPSIS 🎀

dlopen-notes.py [-r] [-s] [-f [FEATURE1,FEATURE2]] [-h] filename
[filename ...]

---

💅 DESCRIPTION 💅

So basically: this tool reads .note.dlopen notes out of ELF files and reports the contents back to you. That's the whole vibe. 🦋

Here's the lore, fr fr: ELF binaries keep their link-time dependencies in their headers, and a bunch of different tools can parse those. But here's the thing — there's no machine-readable metadata by default about dependencies that get loaded at build time via dlopen(3). Like, none. It's giving mystery. 😭

So the ELF Dlopen Metadata specification said "not on my watch" and stepped in to fill that gap by defining a common format. 👑

You can go read all about it at https://systemd.io/ELF_DLOPEN_METADATA/ — highly recommend, iykyk.

And this tool is the one that lets you parse such a note and print the result out in various formats. main character energy tbh. 💜

If no option is specified, --raw is the default. so like, if you just vibe and pass nothing, you get raw JSON. periodt. 🍓
