✨ CANSEQUENCE(1) — the manual page for cansequence ✨

okay bestie, sit down, hydrate, and let me tell you about cansequence 💖 this is the user-commands girlie from the cansequence 2023.03-1build1 era and she is so real for what she does.

🦋 SYNOPSIS 🦋

cansequence [<can-interface>] [Options]

like… that's it. that's the whole vibe. <can-interface> is a placeholder, and then a pile of options. iconic of her honestly.

🌸 DESCRIPTION 🌸

first thing's first, the literal energy she comes out swinging with:

./cansequence: invalid option -- '?'

yeah. that's just in there. no context. no apology. she said what she said 💀

so what does she actually <em>do</em>? cansequence sends CAN messages with a rising sequence number as the payload. that's the whole trick — the numbers go up, up, up 📈

and when you hand her the -r option? she flips the whole thing around and expects to receive those messages instead. and if a wrong sequence number shows up in her inbox, she prints an error message. no chill about it. not sorry.

the main purpose of this program — the main character mission, if you will — is to test the reliability of CAN links. that's it. that's the job. she is a quality-check queen and she takes it very seriously 👑

💅 OPTIONS 💅

every single one, no skips, no cuts, just like she deserves:

  • -e, --extended — send an extended frame 🫶
  • -i, --identifier=ID — set the CAN Identifier (default = 2) ✨
  • --loop=COUNT — send the message COUNT times, over and over, she'll keep going 🔁
  • -p, --poll — use poll(2) to wait for buffer space while sending ⏳
  • -q, --quit <num> — quit if <num> wrong sequences are encountered 🚪
  • -r, --receive — work as receiver, catch those messages instead of throwing them 🎀
  • -v, --verbose — be verbose (twice to be even more verbose 🗣️
  • -h, --help — this help, your little rescue map 🗺️
  • --version — print version information and exit, then she's gone 👋
heads up bestie: -v gets even more chatty if you stack it twice. and yes, that parenthesis in the original is unclosed — I'm keeping it exactly as she wrote it, that's part of her charm 💜

okay that's the whole page!! go test those CAN links, be safe, and remember: rising sequence numbers only, no cap 🔥
