canlock-hfp(1)

💅 canlock-hfp(1) — the header field parser bestie 🌸

okay so real quick, this whole page lives inside the canlock-hp 3.3.2 manual and like… it's a canlock-hfp(1) situation, iykyk. Let's get into it 🫶

---

✨ NAME ✨

canlock-hfp — the CLI frontend for the libcanlock library, periodt 👑

---

🎀 SYNOPSIS 🎀

canlock-hfp -h | -v

canlock-hfp [-d] [-n]

literally that's the whole vibe check, two whole modes 🦋

---

🌸 DESCRIPTION 🌸

So canlock-hfp is the Header Field Parser (hfp, cute acronym, love that for her) for RFC 8315 conformant header fields 💖

The header field gets read from stdin. that's it, that's the input, no cap.

okay but here's the thing — the input data must be an unfolded "Cancel-Lock" or "Cancel-Key" header field with no line break at the end 🚨 like, do not give her a trailing newline, she will not be slayed by that. The utility canlock-mhp(1) can be used to extract the field from an article, so if you need the assist, that's your girl 🤝

If such a header field is found, it gets parsed according to the syntax defined in RFC 8315. And if valid c-lock or c-key (respectively) elements are found, they are printed to stdout with SP (Space) as delimiter. iconic behaviour, honestly ✨

Note: Additional formatting output is printed on stderr to make the output more human readable on a terminal. Redirect stderr to /dev/null if this is not wanted. no seriously, if the extra chatter is giving too much main character energy, just yeet it to /dev/null 💀

---

💅 OPTIONS 💅

The following options are supported, bestie, and yes we're listing all of them:

• -d — Enable debug mode (messages are printed to stderr). Detective mode activated 🔍
• -h — Print help message, then exit. the classic "help me help you" 🫶
• -n — Prepend the data on stdout with the header field name (including the colon) and a SP (Space) delimiter. name tag on, colon and space included 🎀
• -v — Print version and compile time options, then exit. she'll tell you what she's made of 👑

---

⭐ EXIT STATUS ⭐

Zero on success or regular exit respectively. All other values indicate an error.

so like, 0 = we ate and left no crumbs 🍓. anything else = something went sideways, ngl 😭
