✨ NAME ✨

taler-mdb-qr-show — show text encoded as QR code on the framebuffer 🦋

---

🌸 SYNOPSIS 🌸

taler-mdb [-c FILENAME | --config=FILENAME] [-d DELAY | --delay=DELAY]
       [-c FILENAME | --config=FILENAME] [-h | --help]
       [-i | --backlight-invert] [-L _*LOGLEVEL* | --log=LOGLEVEL] [-l
       _*FILENAME* | --logfile=FILENAME] [-v | --version] URL -- PROGRAM

(no, the -c really is in there twice, that's not me being messy, that's canon 💀)

💖 DESCRIPTION 💖

taler-mdb-qr-show is a command-line tool that puts a QR code up on a framebuffer display. icon behavior honestly. ✨

The URL or text you want encoded into the QR code has to be the last argument — like, that's the whole point, don't bury it somewhere in the middle. 🙈

Once the QR code has been chilling on screen for the specified DELAY, the next PROGRAM from the command line gets executed. so it's a little relay race: show the code, wait, hand off. 🏃‍♀️💨

Its options are as follows, bestie, listen up:

• -c FILENAME, `--config=FILENAME — use the configuration and other resources for the Sync commands to operate from FILENAME.
• *-d *DELAY, --delay=*DELAY*** — how long should we display the QR code before running PROGRAM`. to operate from FILENAME.

ok yes, that trailing "to operate from FILENAME." is really in there, it's a whole copy-paste moment, but I'm keeping it because facts are facts and I don't make the rules 🫶

• -h, --help — print short help on options.
• -i, --backlight-invert — invert the bit for turning on/off the backlight. (the humble bit flip, the icon 💅)
• -L LOGLEVEL, `--log=LOGLEVEL — configure logging to use LOGLEVEL.
• -l FILENAME, `--logfile=FILENAME — configure logging to write logs to FILENAME.
• -v, –version — print version information.
