QR ✨💖 (the Python QR tool, bestie edition)

okay so you know qr, right? no? literally the manual name is qr, it lives in section 1 of the manual, and it's from the Python QR tool — and it's about to become your new main character. 🎀

🌸 NAME 🌸

qr — a script to create QR codes at the command line 💅

✨ SYNOPSIS ✨

qr [--help] [--factory=FACTORY] [--optimize=OPTIMIZE]
[--error-correction=LEVEL] [data]

like. that's it. that's the whole vibe. 🦋

💖 DESCRIPTION 💖

bestie listen. this script uses the python qrcode module. it can take data from stdin or from the commandline, and then it generates a QR code. 🫶

normally it will output the QR code as ascii art to the terminal. but — plot twist — if the output is piped to a file, it will output the image instead (default type of PNG). the way it just switches up on you based on where the output's going?? iconic. no cap. 😭✨

💅 OPTIONS 💅

  • -h, --help — show a help message. that's it, that's the whole job, and it ate. 🙈
  • --factory=FACTORY — full python path to the image factory class to create the image with. and because we're nice, you can use these shortcuts to the built-in image factory classes: pil (default), png (default if pillow is not installed), svg, svg-fragment, svg-path. pick your fighter 🎀
  • --optimize=OPTIMIZE — optimize the data by looking for chunks of at least this many characters that could use a more efficient encoding method. use 0 to turn off chunk optimization. she's efficient, she's thorough, she's that girl. ✨
  • --error-correction=LEVEL — the error correction level to use. choices are L (7%), M (15%, default), Q (25%), and H (30%). go higher if you want your code to survive being scuffed, bestie 🦋
  • data — the data from which the QR code will be generated. the whole point. the moment. the reason we're all here. 💖

🔥 SEE ALSO 🔥

heads up bestie: --error-correction only takes L, M, Q, or H. don't be out here typing vibes into it, okay? 💀
