Automaton

Note: This library is still under heavy development.

Automaton is an Elixir library that manages the conversation between your chat bot and the user by maintaining the messages and context in a GenServer.

This is useful as most messaging platforms (webhooks) and NLP services (REST API) communicates with your backend in the typical Request/Response mode.

Automaton aims to be the glue/framework/library to help you focus on your backend instead of messing around with the plumbing of maintaining chat bots.

Quick Start

# In your config/config.exs file
config :sample, Sample.Bot,
  adapter: Automaton.Console.Adapter

# In your application code

# Define your bot
defmodule Sample.Bot do
  use Automaton.Bot, otp_app: :sample

  # Echo backs whatever you said
  def process(sender_id, message, context) do
    reply(sender_id, message, context)
  end
end

# In an IEx session
iex> Sample.Bot.converse("Hello World")
Hello World
:ok

Installation

Add Automaton in your mix.exs dependencies:

def deps do
  [{:automaton, "~> 0.1.0"}]
end

Adapters

Platform	Automaton adapter
Facebook Messenger	Automaton.FacebookMessenger.Adapter
Telegram	Automaton.Telegram.Adapter
Slack	Automaton.Slack.Adapter
Console (Included)	Automaton.Console.Adapter

Configure your adapter in config/config.exs file:

config :sample, Sample.Bot,
  adapter: Automaton.FacebookMessenger.Adapter
  # adapter config (api keys, etc.)

You can also define custom adapters by implementing callbacks defined in adapter.ex

Proposed Roadmap

• Stores conversation message and context
• Adapter layer to support different messaging platforms
• Simple callback to process messages/context
• Access to conversation context
• Terminates stale conversation and logs it
• Callback for conversation termination for custom behavior
• Tracks simple metrics like conversation/messages counts
