eddie 0.9.5

A lib to create chatbots

eddie is a library you can use to create your own chat bots in seconds.

This is a very young library, any request/suggestion/help will be very appreciated. For them, create an issue or contact me!

Install

You can install eddie using just pip:

$ pip install eddie

If you want the latest version download this repository in your project or using pip:

$ pip install git+https://github.com/greenkey/eddie.git

Usage

You have to define your bot class, extending the default Bot class:

>>> from eddie.bot import Bot
>>> class MyBot(Bot):
...     pass
...
>>> b = MyBot()
>>> b
<__main__.MyBot object at 0x7f16e79f3940>

Of course you’ll want to define some bahaviour, the following chapters teach you how to do it.

Defining a default response

>>> from eddie.bot import Bot
>>> class MyBot(Bot):
...     def default_response(self, in_message):
...         # setting echo as default response
...         return in_message
...
>>> b = MyBot()
>>> b.process("Hello!")
'Hello!'
>>> b.process("Goodbye!")
'Goodbye!'

Defining commands

Just define a method of your Bot class using the command decorator.

>>> from eddie.bot import Bot, command
>>> class MyBot(Bot):
...     @command
...     def hello(self):
...             return "hello!"
...
>>> bot = MyBot()
>>> bot.process("/hello") # the default command prepend is "/"
'hello!'

Defining interfaces

A bot running in local would be pretty useless, isn’t it?

The simplest interface we can give to our bot is the http one.

>>> from eddie.bot import Bot
>>> from eddie.endpoints import HttpEndpoint
>>> class MyBot(Bot):
...     def default_response(self, in_message):
...             return in_message
...
>>> bot = MyBot()
>>> ep = HttpEndpoint()
>>> bot.add_endpoint(ep)
>>> bot.run()

Then you can send message to the bot using simple GET requests: http://localhost:8000/process?in_message=hello

Note: default port is 8000, if it is already used, HttpEndpoint will use the first free port after 8000 (8001, 8002…).

The output using the example will be a json with the message: {"out_message": "hello"}

Telegram

Yes, you can easily connect your bot with the Telegram API, thanks to the python-telegram-bot library.

You don’t have to worry about nothing, except getting a token from the BotFather and passing it to your bot.

>>> from eddie.bot import Bot
>>> from eddie.endpoints import TelegramEndpoint
>>> class MyBot(Bot):
...     def default_response(self, in_message):
...             return in_message
...
>>> bot = MyBot()
>>> ep = TelegramEndpoint(
...     token='123:ABC'
... )
>>> bot.add_endpoint(ep)
>>> bot.run()

Twitter

It’s not a proper bot framework, but with eddie you can have a bot in Twitter too, thanks to the tweepy library.

Just follow the instrunction on how to create a Twitter App , get all the tokens and use them to instantiate the TwitterEndpoint.

>>> from eddie.bot import Bot
>>> from eddie.endpoints import TwitterEndpoint
>>> class MyBot(Bot):
...     def default_response(self, in_message):
...             return in_message
...
>>> bot = MyBot()
>>> ep = TwitterEndpoint(
...     consumer_key='your consumer_key',
...     consumer_secret='your consumer_secret',
...     access_token='your access_token',
...     access_token_secret='your access_token_secret'
... )
>>> bot.add_endpoint(ep)
>>> bot.run()

Logging

This library uses the logging module. To set up logging to standard output, put:

import logging
logging.basicConfig(level=logging.DEBUG)

at the beginning of your script.
