# Contributing Kalliope needs the community to improve its Core features and to create new Neurons. Let's join us ! ## Core The community can contribute to the Core of Kalliope by providing some new features. ### How to contribute 1. Fork it! 2. Create your feature branch: `git checkout -b my-new-feature` 3. Commit your changes: `git commit -am 'Add some feature'` 4. Push to the branch: `git push origin my-new-feature` 5. Submit a pull request :D ## Neurons Kalliope modularity is fully based on Neuron so the community can contribute by adding their own. Neurons are independent projects so they can be developed under a github project. Anyone can clone them, place them under the neurons repository and reuse them. Creating a new Neuron must follow some rules: ##### Repository Structure 1. The Neuron repository name is in __lowercase__. 1. The Neuron repository must be added under the __neurons__ repository coming from the Core. 1. Under the Neuron repository, the Neuron has a __README.md file__ describing the Neuron following this structure: - Neuron name: - Synopsis: Description of the Neuron - Options: A table of the incoming parameters managed by the Neuron. - Return Values: A table of the returned values which can be catched by the *say_template attribute*. - Synapses example: An example of how to use the Neuron inside a Synapse. - Notes: Something which needs to be add. 1. Under the Neuron repository, include a __Tests repository__ to manage the test of the Neuron. ##### Code 1. Under the Neuron repository, the Neuron file name .py is also in __lowercase__. 1. The Neuron must be coded in __Python 2.7__. 1. Under the Neuron repository, include the __init__.py file which contains: *from neuron import Neuron* (/!\ respect the Case) 1. Inside the Neuron file, the Neuron Class name is in __uppercase__. 1. The Neuron __inherits from the NeuronModule__ coming from the Core. ``` from core.NeuronModule import NeuronModule class Say(NeuronModule): ``` 1. The Neuron has a constructor __init__ which is the entry point. The constructor has a __**kwargs argument__ which is corresponding to the Dict of incoming variables:values defined either in the brain file or in the signal. 1. The Neuron must refer to its __parent structure__ in the init by calling the super of NeuronModule. ``` def __init__(self, **kwargs): super(Say, self).__init__(**kwargs) ``` 1. (*optionnal-> good practice*) The Neuron can implement a __private method _is_parameters_ok(self)__ which checks if entries are ok. *return: true if parameters are ok, raise an exception otherwise* 1. (*optionnal-> good practice*) The Neuron can __import and raise exceptions__ coming from NeuronModule: - MissingParameterException: *Some Neuron parameters are missing.* - InvalidParameterException: *Some Neuron parameters are invalid.* 1. The Neuron can use a __self.say(message) method__ to speak out some return values using the *say_template* attribute in the brain file. the message variable must be a Dict of variable:values where variables can be defined as output. ##### Constraints 1. The Neuron must (as much as possible) ensure the i18n. This means that they should __not manage a specific languages__ inside its own logic. Only [Synapse](brain.md) by the use of [Order](signals.md) must interact with the languages. This allow a Neuron to by reused by anyone, speaking any language. ##### Limitations 1. The management of incoming variable from the signal order when they are numbers or float are not efficient. (Thanks to @thebao for pointing this out!) - Because of the differences between the STTs outputs: some are returning word some numbers (two != 2). - Because of the i18n, we are not able to know if a variable should be interpreted in english, french, spanish, etc ... ("two" != "deux" != "dos") ## STT, TTS, Trigger They are managed like Neurons, you can follow the same process to develop your own ! ## Share it *Incoming* We are maintening a list of all the Neurons available from the community, let us know
