Feature request: Excluding specific files

[hinok]

Hey,
It's just proposal of a new feature that could be very handy.

I would like to exclude some files which are added to generated index.js files, why?
I have a folder /icons witch contains all my icons (each icon is a react component).
In this folder I have also stories.js file (I'm using react-storybook). Now stories.js is always added to the end of the file and my storybook is broken.

I think that it could work also for other people in other more advanced cases.
I could implement it and add PR but before I would like to talk about proposed solutions.

1. Using a "special comment" in generated index.js file

// @create-index
// @create-index-ignore: [/stories.(js)$/]

export Abc from './Abc.js';
export Zxc from './Zxc.js';
export Qwe from './Qwe.js';

.2 Using a "special configuration file" .create-index inside a specific directory

.create-index

{
  ignore: [
    /stories.(js)$/
  ]
}

I don't think it makes sense to use a configuration file (yes another dot-file in the project for no good reason).

I'd say a variation of providing configuration in comment is a good approach, e.g.

// @create-index {"ignore": ["stories.(js)$"]}

1. We keep the // @create-index comment as it.
2. We change the // @create-index check to allow arbitrary string to follow the comment.
3. We require assume that anything that follows // @create-index (on the same line) is a configuration object (defined as JSON).

This needs to be done in two PRs: (1) enable the above logic, (2) add ignore configuration.

This is quite a substantial amount of work. Though, if you'd raise the PRs, I'd be happy to review and and publish it.

Was any work done on this feature?

@advance512 I had an unexpected problem with my health and I couldn't start working on it in the last few weeks. I think that I'll be able to start implementation in the next week.

Feel well, @hinok! Thanks for any help :)
