✨ NAME ✨

like. that's the whole vibe. MDB vending machine + Taler = this program.

🌈 SYNOPSIS 🌈

taler-mdb [-c FILENAME | --config=FILENAME] [-d | --disable-mdb]
[-h | --help] [-i | --backlight-invert] [-L
_*LOGLEVEL* | --log=LOGLEVEL] [-l _*FILENAME* | --logfile=FILENAME]
[-s | --enable-soldout] [-t | --disable-tty] [-v | --version]

that's the whole shape of it — every flag you can possibly throw at her, all lined up. copy it, paste it, it's giving cheat sheet 😌

💖 DESCRIPTION 💖

taler-mdb is a command-line tool to operate a vending machine using GNU Taler for payments. no cap, that's the entire job description: she talks to the machine, she handles the money, she keeps the snacks flowing. 🔥

Its options are as follows — buckle up, there's nine of them and every single one matters:

  • -c FILENAME, --config=FILENAME — use the configuration and other resources for the Sync commands to operate from FILENAME. yes, it says "Sync commands", that's just what the original says, I don't make the rules 🫶
  • -d, --disable-mdb — disable interaction with the MDB bus, for testing. so she'll run but she won't actually poke the hardware — perfect for when you're just vibing in a dev environment and don't have a real vending machine plugged in 🙈
  • -h, --help — print short help on options. the classic. the icon. when in doubt, ask for help ✨
  • -i, --backlight-invert — invert the bit for turning on/off the backlight. one bit, flipped, and suddenly your LED situation makes sense. it's giving ~ energy 💅
  • -L LOGLEVEL, --log=LOGLEVEL — configure logging to use LOGLEVEL. you want more or less chatter? this is the dial 🎀
  • -l FILENAME, --logfile=FILENAME — configure logging to write logs to FILENAME. so the chatter goes into a file instead of your terminal, and your terminal stays zen 🌸
  • -s, --enable-soldout — when the machine fails to dispense a product, internally set the product to "sold out" and refuse future orders until restarted. honestly? iconic. she remembers the trauma and she protects future customers from it 😭
  • -t, --disable-tty — disable interactive command-line use. so she stops waiting on a human and just does her thing 🦋
  • -v, –version — print version information. drop the number, look cool, move on ⭐
