📦 version 1.3.0, in nixos 26.05, nixpkgs unstable

💅 NAME

taler-merchant-exchangekeyupdate — the little background bestie that keeps your exchange key material all fresh and up-to-date ✨

🦋 SYNOPSIS

taler-merchant-exchangekeyupdate [-c FILENAME | --config=FILENAME]
[-h | --help] [-L LOGLEVEL | --loglevel=LOGLEVEL]
[-l FILENAME | --logfile=FILENAME] [-T USEC | --timetravelUSEC]
[-t | --test] [-v | --version]

🌸 DESCRIPTION

Okay so picture this: taler-merchant-exchangekeyupdate is a background job — like, the invisible main character working behind the scenes — and what it does is download the current key material and configuration data from every exchange you've got configured, then keeps a nice up-to-date copy of all of it in your local database. Lowkey essential. 💖

This tool is part of a whole set of processes that let a merchant backend be absolutely sure it can properly interact with an exchange. No awkward "wait, who are you?" moments. iykyk.

Its options are as follows, bestie — read them all, they're all important:

  • -c FILENAME, --config=FILENAME — Use the configuration and other resources for the merchant to operate from FILENAME. Basically: here's where all my stuff lives, go look there 🎀
  • -h, --help — Print short help on options. Your emergency backup bestie when you forget a flag.
  • -L LOGLEVEL, --loglevel=LOGLEVEL — Specifies the log level to use. Accepted values are: DEBUG, INFO, WARNING, ERROR. Pick your vibe check level 🌈
  • -l FILENAME, --logfile=FILENAME — Send logging output to FILENAME. So it has somewhere to journal about its day.
  • -T USEC, --timetravel=USEC — Modify the system time by USEC microseconds. USEC may be prefixed with + or - (e.g. -T +300). ⏰
ngl this one is intended for debugging/testing only — do not be out here time-travelling in production, that's giving chaos and it will not slay 😭
  • -t, --test — Run in test mode. Only runs until the current list of bank transactions have all been checked. Like a little trial run, then it dips. 🫶
  • -v, –version — Print version information. Iconic little flex.
