_ = r"""
announces a new upload on discord

example usage as global config:
    --xau f,t5,j,bin/hooks/discord-announce.py

parameters explained,
    xau = execute after upload
    f  = fork; don't delay other hooks while this is running
    t5 = timeout if it's still running after 5 sec
    j  = this hook needs upload information as json (not just the filename)

example usage as a volflag (per-volume config):
    -v srv/inc:inc:r:rw,ed:c,xau=f,t5,j,bin/hooks/discord-announce.py
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    (share filesystem-path srv/inc as volume /inc,
     readable by everyone, read-write for user 'ed',
     running this plugin on all uploads with the params explained above)

example usage as a volflag in a copyparty config file:
    [/inc]
      srv/inc
      accs:
        r: *
        rw: ed
      flags:
        xau: f,t5,j,bin/hooks/discord-announce.py

replace "xau" with "xbu" to announce Before upload starts instead of After completion

# how to discord:
first create the webhook url; https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks
then use this to design your message: https://discohook.org/
