Inherit comments from spread prop types

[milesj]

I haven't seen this anywhere in the documentation, and it definitely is not supported right now, but it would be great if the docs could inherit comments from objects who were spread into propTypes, like the following.

const propTypes = {
  /* This does something. */
  bar: PropTypes.node,
};

export default function Foo(props) {
  return <div />;
}

Foo.propTypes = {
  ...propTypes,
};

Foo.defaultProps = {
  bar: null,
};

As it stands, styleguidist shows the bar prop, but without a comment.

I think this is something that react-docgen (which parses js files for info for react-styleguidist to consume) should do.

Thanks, I'll cross post it there too. reactjs/react-docgen#246

@milesj , As @n1313 said its defiantly a bug(at least not supported) of react-docgen. And just to add that react-docgen doesn't support spread operator.

I’m going to close this for now, because there’s nothing we can do on our side.
