Support Object.assign in propTypes definition

In my React App, I have components which pass receive properties but just pass them as is to their child component. The parent component sort of extends the child component properties, so I'm using Object.assign to avoid code duplication. Unfortunately, recat-docgen doesn't seem to handle propTypes values which are evaluated from a function.

For example, let's say I have a component named ParentComponent and a component named ChildComponent.

The render function of the ParentComponent looks like this:

render() {
  return (
    <ChildComponent childPropA="SomeValue" childPropB="AnotherValue" />
  );
}

When I render the ParentComponent my code looks like this:

<ParentComponent parentPropA="Value" childPropA="SomeValue" childPropB="AnotherValue" />

Therefore, I use Object.assign for setting ParentComponent.propTypes:

ParentComponent.propTypes = Object.assign({}, ChildComponent.propTypes, {
  parentPropA: React.PropTypes.string
});

Aucun fichier source ni aucun test n’est nommé. Commencez par suivre la manière dont react-docgen évalue les propTypes des composants, puis reproduisez l’exemple Object.assign de l’issue. C’est terminé lorsque les propTypes hérités et définis localement sont tous deux correctement extraits, avec un test de régression couvrant l’exemple.
