#!/usr/bin/env bash
# notify a khal user via rofi about upcoming events
#
# dependencies: ·khal
# ·rofi >= 1.7.0 (-timeout-delay 60 -timeout-action "kb-cancel")
# ·column (eye candy only. can be removed without problems)
#
# usage: put it into a cronjob and let it run every 15 min or so
# -only events with reminders will trigger an alarm (shown in khal as: ⏰)
# -snoozed events will show up again on the next run
# -dismissed events will not trigger an alarm again
# -no alarm will be triggered if the script did never run
# for the duration of an event or in TIMESPAN beforehand
#
# rofi: -Shift+Return toggles item selection
# -if any item is selected, "cursor" position has no effect
# -timeout after 60 seconds; this snoozes all events
