Building a new Intent

Remember that when we set an intent in a determinate Ava instance we only need code:

import intentName from './intentName.js';

ava.intent(intentName, action);

Ava will process your intent definition and will queue it on intents list to execute. But... what is your intent definition?, well you will receive two parameters:

• state: the actual object state.
• actions: a array of actions to execute if intent is successful.

Lets see the basic definition of your intent:

intentName.js

import { resolve } from 'ava-ia/lib/helpers'

export default (state, actions) => {
  resolve(state);
};

All intents must be resolved with the state (like a promise) but maybe your function it isn't a promise (async) for that reason we build the helper resolve. Just call it and your intent will be part of the factory of intents. Now we will see a complete example, our intent will:

• check if a list of terms are part of state attributes tokens and classifier
• check if the sentence has a specific syntax

'use strict';

import { factoryActions, intersect, syntax, resolve } from 'ava-ia/lib/helpers'
// -- Internal
const TERMS = [ 'film', 'movie' ];
const RULES = [
  '[Person] want see [Noun]',
];

export default (state, actions) => {
  const tokens = intersect(TERMS, state.tokens);
  const classifiers = intersect(TERMS, state.classifier);
  const match = syntax(state.sentence, RULES);

  if (tokens || classifiers || match) {
    return factoryActions(state, actions);
  } else {
    return resolve(state);
  }
};

As you can see, if we have tokens, or classifiers or match fulfilled we will call to our actions using the helper factoryActions. Easy right?
