# This script queries the Travelynx API if you are checked into a train. If
# yes, marudor.de is additionally queried for the next stop, and a JSON object
# like this is written to stdout:
# {"full_text": "RE26824, next: D\u00fcren at <span fgcolor=\"#ff0000\">15:38+5</span>, dest: Aachen Hbf at <span fgcolor=\"#ff0000\">16:07+5</span>", "markup": "pango"},
# The script then exits.
#
# Configuration:
# - Place your API key from https://travelynx.de/account at
# ~/.config/travelynx.conf .
# - Then integrate into whatever generates your i3bar input.
# - Make sure you use i3bar with a pango font, so that the color tags are
# picked up.
