Overview




Leon

Your open-source personal assistant.



Website :: Documentation :: Roadmap :: Contributing :: Story

👋 Introduction

Leon is an open-source personal assistant who can live on your server.

He does stuff when you ask him for.

You can talk to him and he can talk to you. You can also text him and he can also text you. If you want to, Leon can communicate with you by being offline to protect your privacy.

Why?

  1. If you are a developer (or not), you may want to build many things that could help in your daily life. Instead of building a dedicated project for each of those ideas, Leon can help you with his packages/modules (skills) structure.
  2. With this generic structure, everyone can create their own modules and share them with others. Therefore there is only one core (to rule them all).
  3. Leon uses AI concepts, which is cool.
  4. Privacy matters, you can configure Leon to talk with him offline. You can already text with him without any third party services.
  5. Open source is great.

What is this repository for?

This repository contains the following nodes of Leon:

  • The server
  • The packages/modules
  • The web app
  • The hotword node

What is Leon able to do?

Today, the most interesting part is about his core and the way he can scale up. He is pretty young but can easily scale to have new features (packages/modules). You can find what he is able to do by browsing the packages list.

Sounds good for you? Then let's get started!

  • Python && python3

    Python && python3

    Bonsoir, c'est difficile de mettre ce léon en place, mais je vais y arriver. J'ai un petit problème avec ce python et python3, léon ne detecte pas mon python3 (lors du check) car sur la derniere version derbian la version 2 est toujours utilisé. (Je ne suis pas un pro de linux). Donc suivant les forums on deconseil de remplacer python2 par python3 par defaut. Pourquoi est-ce que léon ne va pas chercher lui meme sa version lorsque les deux sont installés sur la machine? (c'est un detail, voir au mieux une idee). Bon je pense que je peux laisser python (python2) sur mon systeme et configurer léon pour qu'il utilise python3 a la place. Quel est le finchier de conf a modifier pour faire ca, si c'est possible

  • How to update the packages?

    How to update the packages?

    How can I test my packages?

    I am trying to add some modules in the Existing package. I have added the quotes module in the leon package.

    I added this inleon/data/expressions/en.json

    
"quote": [
		"Tell me a Quote",
		"Give me a Quote",
	]

    Then I have updated the below in ` leon/data/expressions/en.json

    
"quote":{ 
  	  "quotes":
  	   [
		  "Design is the silent ambassador of your brand. ",
		  "If there is one word I’d like to remove from any conversation about design, it’s “pretty.",
	   ]
    }

    Then I create a new python file named quote.py. Please see the below code.

    import utils

def quote(string):
	"""Leon says some quote"""

	return utils.output('end', 'quotes', utils.translate('quotes'))

    I also created a new test python file in the test folder.

    But it seems it breaks leon. Wheneve I ask question it gives reply as "Sorry, I don't work correctly!"

    How can I test the modules? Do I need to add anything else?
