tock-py

Build chatbots using Tock and Python

DISCLAIMERS

• Work in progress
• Not production ready
• not yet implemented
  • Managing User / conversational context
  • Testing

Prerequisites

Run a Tock bot in API mode

Create a Bot application using the web connector type in Tock Studio and get your API key

Environment

We suggest you to create an isolated Python virtual environment:

$ python3 -m venv env
$ source env/bin/activate

Install tock-py on your project

$ pip install tock-py

Usage

import logging
import os

from tock.bot import TockBot
from tock.bus import TockBotBus
from tock.story import story

logging.basicConfig(
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
    level=logging.DEBUG
)

# First create story that handle "greetings" intent
@story(
    intent="greetings",
    other_starter_intents=[],
    secondary_intents=[]
)
def greetings(bus: TockBotBus):
    bus.send("Hello i'm a tock-py bot")

# If decorator @story is not provided, the intention with the function name is user
def goodbye(bus: TockBotBus):
    bus.send("Hello i'm a tock-py bot")

# Configure your bot and start it
TockBot() \
    .register_story(greetings) \
    .register_story(goodbye) \
    .start_websocket(apikey=os.environ['TOCK_APIKEY'])


# You can also use webhook mode
# TockBot() \
#     .register_story(greetings) \
#     .register_story(goodbye) \
#     .start_webhook("0.0.0.0", "tock-py", 5000)

Sentence

bus.send("Hello i'm a tock sentence")

Suggestion

bus.send(
    Sentence.Builder("Hello i'm a tock sentence")
        .add_suggestion("with suggestion")
        .build()
)

Card with action

bus.send(
    Card
        .Builder()
        .with_title("card title")
        .with_sub_title("with subtitle")
        .with_attachment("https://www.sncf.com/themes/sncfcom/img/favicon.png", AttachmentType.IMAGE)
        .add_action("visit", "http://www.sncf.com")
        .build()
)

Carousel

card = Card \
    .Builder() \
    .with_title("Card title") \
    .with_sub_title("wit subtitle") \
    .with_attachment("https://www.sncf.com/themes/sncfcom/img/favicon.png", AttachmentType.IMAGE) \
    .add_action("visit", "http://www.sncf.com") \
    .build()
    
bus.send(
    Carousel
        .Builder()
        .add_card(card)
        .add_card(card)
        .add_card(card)
        .build()
)

Custom state

Your bot can store custom state data in session

def greetings(bus):
    if bus.session.get_item("greetings_flag") is None:
        bus.send("Welcome")
    else:
        bus.send("Welcome back")
    bus.session.set_item("greetings_flag", True)

You can clear session

def goodbye(bus):
    bus.session.clear()
