On Github its a mirror from private Gitlab repo

Would like to thank AppSignal for considering my project under their OpenSource initiative and setting up a free account for APM. I hope this helps others at using their product. Its one of the most comprehensive tools available for Elixir monitoring.

UltronEx - Ultron in Elixir

Its my first attempt at writing elixir, the code might not very elixirish. This is a rewrite of a slack bot I did few years ago in ruby. Blog post showcasing the results elixir outperforming ruby by 100%

command(s)
      --> help #list the command list
      --> mute/talk #TODO implement later
      --> xkcd #shows a random xkcd comic
      --> xkcd <comic no> #shows xkcd comic no
      --> gif #shows random gif
      --> gif <category> #show a random gif from the category
      --> quote #shares a quote
      --> forward <term> #sets up msg forwarding for the term from SLACK_CHANNEL_LIST
      --> stop <term> #stops msg forwarding for the term from SLACK_CHANNEL_LIST
      --> stop #stops all msg forwarding set for SLACK_CHANNEL_LIST
      --> any msg # responds with a quote

TODO: make it more elixir-ish
