pylexa 0.0.13

Example

Let’s say you want to define an Alexa Skill that echoes whatever the user says. So far, you’ve:

• created a skill in the Amazon Developer Console

• Added a Echo intent with a single slot, message:

  {
    "intent": "Echo",
    "slots": [
      {
        "name": "message",
        "type": "AMAZON.LITERAL"
      }
    ]
  }

• Added an utterance to allow users to interact with the skill:

  Echo echo { something | message }

Now, you’re ready to create a server that will accept the request and return a response echoing the input. Using pylexa, we’d need only the following code to accomplish this:

from flask import Flask

from pylexa.app import alexa_blueprint
from pylexa.intent import handle_intent
from pylexa.response import AlexaResponseWrapper, PlainTextSpeech


app = Flask(__name__)
alexa_blueprint.app_id = 'my_app_id'
app.register_blueprint(alexa_blueprint)
app.response_class = AlexaResponseWrapper


@handle_intent('Echo')
def handle_echo_intent(request):
    return PlainTextSpeech(request.slots.get('message', 'Nothing to echo'))

And that’s it! You can push the above code, configure the skill to point to the server running the flask app and use the service simulator to test your skill.

Testing

After installing requirements with pip install -r requirements.pip, tests can be run with nosetests.
