/*
Three people are playing the following betting game.
Every five minutes, a turn takes place in which a random player rests and the other two bet
against one another with all of their money.
The player with the smaller amount of money always wins,
doubling his money by taking it from the loser.
For example, if the initial amounts of money are 1, 4, and 6,
then the result of the first turn can be either
2,3,6 (1 wins against 4);
1,8,2 (4 wins against 6); or

Learning Erlang / Elixir Basics

Primitives

Erlang only has a few primitives that you need to worry about. Here they are below with corresponding Elixir examples.

1. integer: Erlang: 123, Elixir: 123
2. float: Erlang: 123.5, Elixir: 123.5
3. atom: Erlang: hello, Elixir: :hello
4. binary: Erlang: <<"hello">> or <<10,20>>, Elixir: "hello" or <<10,20>>

Playing with elixir and slackbots!

So I've come across a nice, little elixir slackbot (if you've googled it you've seen it: https://github.com/BlakeWilliams/Elixir-Slack) It seems to do everything I want in a slack bot except botkit's hears functionality. So here is a quick draft to do just that:

def hears(message, slack) do
  to_hear = [
    %{regex: ~r/^hello.*/i, cb: fn msg, slack -> send_message("Why hello", message.channel, slack) end},
 %{regex: ~r/^sup.*/i, cb: fn msg, slack -> send_message("Not much yo", message.channel, slack) end},

or                :   {token,{'T_OR',TokenLine,list_to_atom(TokenChars)}}.
and               :   {token,{'T_AND',TokenLine,list_to_atom(TokenChars)}}.
{T_VAR}+          :   {token,{'T_VAR',TokenLine,TokenChars}}.
[()]              :   {token,{list_to_atom(TokenChars),TokenLine}}.
