schema dsl parse

var schema = require('schema-util').schema;

var json = schema(`
  Array(foo) {
    href(href),
    title(title),
    img(image url): Image,
    amount(money amout)
  }
`);
// json should be so:
/**
  {
    type: 'array',
    description: 'foo',
    properties: {
      href: { description: 'href', type: 'string' },
      title: { description: 'title', type: 'string' },
      img: { description: 'image url', type: 'image' },
      amount: { description: 'money amount', type: 'string' }
    }
  }
*/

And nest rule supported:

var json = schema(`
  Object(abc) {
    title(title),
    user(user): Object {
      name(user name),
      age(user age): Number
    }
  }
`, ['number']);

The secend argument, you can add some more type support, such asage.number, background.color.

schema(`Array(foo) { a(a)}`, types)

The defaultType is 'string', If you want change this, you need send the secend argument like this:

schema(`Array(foo) { a(a)}`, {
  defaultType: 'number',
  supported: ['string']
});

export support

schema(`
  export a Object(hello) { ... }

  export b Array(hello b) { ... }
`);
