# eslint-find-new-rules

## Deprecation Notice

**This module is deprecated in favor of [eslint-find-rules](https://www.npmjs.com/package/eslint-find-rules/)**

---

Use this for your own [ESLint](http://eslint.org/) [shareable configuration](http://eslint.org/docs/developer-guide/shareable-configs)
to identify built-in ESLint rules that you're not explicitly configuring.

## Installation

Simply install locally as a development dependency to your project's package:

```
npm install --save-dev eslint-find-new-rules
```

## Usage

The intended usage is as an npm script:

```javascript
{
  ...
  "scripts": {
    "find-new-rules": "eslint-find-new-rules path/to/eslint-config"
  }
  ...
}
```

Then run it with: `$ npm run find-new-rules -s` (the `-s` is to silence npm output).

### Specify a file

This is really handy in an actual config module (like [mine](https://github.com/kentcdodds/eslint-config-kentcdodds)) where you could also do:

```
eslint-find-new-rules ./index.js
```

This is resolved relative to the `process.cwd()` which, in the context of npm scripts is always the location of your `package.json`.

You may specify any [config format supported by ESLint](http://eslint.org/docs/user-guide/configuring).

### Absolute Path

You can also provide an absolute path:

```
eslint-find-new-rules ~/Developer/eslint-config-kentcdodds/index.js
```

**Please note** that any tested ESLint config file must reside below your project's root.

### Default to `main`

It will also default to the `main` in your `package.json`, so you can omit the argument altogether:

```
eslint-find-new-rules
```

### As a `require`d module

```
var getRuleFinder = require('./eslint-find-new-rules')
var ruleFinder = getRuleFinder('path/to/eslint-config')

// default to the `main` in your `package.json`
// var ruleFinder = getRuleFinder()

// get all the current, plugin, available and unused rules
// without referring the extended files or documentation

ruleFinder.getCurrentRules()

ruleFinder.getPluginRules()

ruleFinder.getAllAvailableRules()

ruleFinder.getUnusedRules()
```
