Elixir interface to AnyBar

First, add AnyBar to your mix.exs dependencies:

def deps do
  [{:anybar, "~> 0.3.0"}]
end

Then, update your dependencies:

$ mix deps.get

Your program can interact with AnyBar through the API:

AnyBar.change("orange")
#=> :ok

AnyBar.change("red", 12345)
#=> :ok

Or by running a mix task:

$ mix anybar orange

Or by installing the escript:

$ mix escript.install hex anybar
./anybar blue
