WIP: Implemented the 'lookups' function and added documentation for it.

[jesselee34]

The lookups function accepts a RegentRule and returns an array of the lookups referenced by that rule. The RegentRule provided can be arbitrarily complex.

Arguments

• RegentRule (Plain Object)

Returns

Array: an array containing all the lookups present in the provided rule.

Example

import { equals, lessThan, lookups } from 'regent';

const isRaining = equals('@weather.precipitation', true);
const isCalm = lessThan('@weather.wind.speed', 25);
const isRainingAndCalm = and(isRaining, isCalm);

const paths = lookups(isRainingAndCalm);

// [
//   '@weather.precipitation',
//   '@weather.wind.speed',
// ]
