+/**
+ * @fileoverview `ConfigArray` class.
+ *
+ * `ConfigArray` class expresses the full of a configuration. It has the entry
+ * config file, base config files that were extended, loaded parsers, and loaded
+ * plugins.
+ *
+ * `ConfigArray` class provides three properties and two methods.
+ *
+ * - `pluginEnvironments`
+ * - `pluginProcessors`
+ * - `pluginRules`
+ *      The `Map` objects that contain the members of all plugins that this
+ *      config array contains. Those map objects don't have mutation methods.
+ *      Those keys are the member ID such as `pluginId/memberName`.
+ * - `isRoot()`
+ *      If `true` then this configuration has `root:true` property.
+ * - `extractConfig(filePath)`
+ *      Extract the final configuration for a given file. This means merging
+ *      every config array element which that `criteria` property matched. The
+ *      `filePath` argument must be an absolute path.
+ *
+ * `ConfigArrayFactory` provides the loading logic of config files.

+# ignore
+
+`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the .gitignore [spec](http://git-scm.com/docs/gitignore).
+
+Pay attention that [`minimatch`](https://www.npmjs.org/package/minimatch) does not work in the gitignore way. To filter filenames according to .gitignore file, I recommend this module.
+
+##### Tested on
+
+- Linux + Node: `0.8` - `7.x`
+- Windows + Node: `0.10` - `7.x`, node < `0.10` is not tested due to the lack of support of appveyor.
+
+Actually, `ignore` does not rely on any versions of node specially.
+
+Since `4.0.0`, ignore will no longer support `node < 6` by default, to use in node < 6, `require('ignore/legacy')`. For details, see [CHANGELOG](https://github.com/kaelzhang/node-ignore/blob/master/CHANGELOG.md).
+
+## Table Of Main Contents
+
+- [Usage](#usage)
+- [`Pathname` Conventions](#pathname-conventions)
+- [Guide for 2.x -> 3.x](#upgrade-2x---3x)
+- [Guide for 3.x -> 4.x](#upgrade-3x---4x)
+- See Also:
+  - [`glob-gitignore`](https://www.npmjs.com/package/glob-gitignore) matches files using patterns and filters them according to gitignore rules.
+
+## Usage
+
+```js
+import ignore from 'ignore'
+const ig = ignore().add(['.abc/*', '!.abc/d/'])
+```
+
+### Filter the given paths
+
+```js
+const paths = [
+  '.abc/a.js',    // filtered out
+  '.abc/d/e.js'   // included
+]
+
+ig.filter(paths)        // ['.abc/d/e.js']
+ig.ignores('.abc/a.js') // true
+```
+
+### As the filter function
+
+```js
+paths.filter(ig.createFilter()); // ['.abc/d/e.js']
+```
+
+### Win32 paths will be handled
+
+```js
+ig.filter(['.abc\\a.js', '.abc\\d\\e.js'])
+// if the code above runs on windows, the result will be
+// ['.abc\\d\\e.js']
+```
+
+## Why another ignore?
+
+- `ignore` is a standalone module, and is much simpler so that it could easy work with other programs, unlike [isaacs](https://npmjs.org/~isaacs)'s [fstream-ignore](https://npmjs.org/package/fstream-ignore) which must work with the modules of the fstream family.
+
+- `ignore` only contains utility methods to filter paths according to the specified ignore rules, so
+  - `ignore` never try to find out ignore rules by traversing directories or fetching from git configurations.
+  - `ignore` don't cares about sub-modules of git projects.
+
+- Exactly according to [gitignore man page](http://git-scm.com/docs/gitignore), fixes some known matching issues of fstream-ignore, such as:
+  - '`/*.js`' should only match '`a.js`', but not '`abc/a.js`'.
+  - '`**/foo`' should match '`foo`' anywhere.
+  - Prevent re-including a file if a parent directory of that file is excluded.
+  - Handle trailing whitespaces:
+    - `'a '`(one space) should not match `'a  '`(two spaces).
+    - `'a \ '` matches `'a  '`
+  - All test cases are verified with the result of `git check-ignore`.
+
+# Methods
+
+## .add(pattern: string | Ignore): this
+## .add(patterns: Array<string | Ignore>): this
+
+- **pattern** `String | Ignore` An ignore pattern string, or the `Ignore` instance
+- **patterns** `Array<String | Ignore>` Array of ignore patterns.
+
+Adds a rule or several rules to the current manager.
+
+Returns `this`
+
+Notice that a line starting with `'#'`(hash) is treated as a comment. Put a backslash (`'\'`) in front of the first hash for patterns that begin with a hash, if you want to ignore a file with a hash at the beginning of the filename.
+
+```js
+ignore().add('#abc').ignores('#abc')    // false
+ignore().add('\#abc').ignores('#abc')   // true
+```
+
+`pattern` could either be a line of ignore pattern or a string of multiple ignore patterns, which means we could just `ignore().add()` the content of a ignore file:
+
+```js
+ignore()
+.add(fs.readFileSync(filenameOfGitignore).toString())
+.filter(filenames)
+```
+
+`pattern` could also be an `ignore` instance, so that we could easily inherit the rules of another `Ignore` instance.
+
+## <strike>.addIgnoreFile(path)</strike>
+
+REMOVED in `3.x` for now.
+
+To upgrade `ignore@2.x` up to `3.x`, use
+
+```js
+import fs from 'fs'
+
+if (fs.existsSync(filename)) {
+  ignore().add(fs.readFileSync(filename).toString())
+}
+```
+
+instead.
+
+## .filter(paths: Array<Pathname>): Array<Pathname>
+
+```ts
+type Pathname = string
+```
+
+Filters the given array of pathnames, and returns the filtered array.
+
+- **paths** `Array.<Pathname>` The array of `pathname`s to be filtered.
+
+### `Pathname` Conventions:
+
+#### 1. `Pathname` should be a `path.relative()`d pathname
+
+`Pathname` should be a string that have been `path.join()`ed, or the return value of `path.relative()` to the current directory.
+
+```js
+// WRONG
+ig.ignores('./abc')
+
+// WRONG, for it will never happen.
+// If the gitignore rule locates at the root directory,
+// `'/abc'` should be changed to `'abc'`.
+// ```
+// path.relative('/', '/abc')  -> 'abc'
+// ```
+ig.ignores('/abc')
+
+// Right
+ig.ignores('abc')
+
+// Right
+ig.ignores(path.join('./abc'))  // path.join('./abc') -> 'abc'
+```
+
+In other words, each `Pathname` here should be a relative path to the directory of the gitignore rules.
+
+Suppose the dir structure is:
+
+```
+/path/to/your/repo
+    |-- a
+    |   |-- a.js
+    |
+    |-- .b
+    |
+    |-- .c
+         |-- .DS_store
+```
+
+Then the `paths` might be like this:
+
+```js
+[
+  'a/a.js'
+  '.b',
+  '.c/.DS_store'
+]
+```
+
+Usually, you could use [`glob`](http://npmjs.org/package/glob) with `option.mark = true` to fetch the structure of the current directory:
+
+```js
+import glob from 'glob'
+
+glob('**', {
+  // Adds a / character to directory matches.
+  mark: true
+}, (err, files) => {
+  if (err) {
+    return console.error(err)
+  }
+
+  let filtered = ignore().add(patterns).filter(files)
+  console.log(filtered)
+})
+```
+
+#### 2. filenames and dirnames
+
+`node-ignore` does NO `fs.stat` during path matching, so for the example below:
+
+```js
+ig.add('config/')
+
+// `ig` does NOT know if 'config' is a normal file, directory or something
+ig.ignores('config')    // And it returns `false`
+
+ig.ignores('config/')   // returns `true`
+```
+
+Specially for people who develop some library based on `node-ignore`, it is important to understand that.
+
+## .ignores(pathname: Pathname): boolean
+
+> new in 3.2.0
+
+Returns `Boolean` whether `pathname` should be ignored.
+
+```js
+ig.ignores('.abc/a.js')    // true
+```
+
+## .createFilter()
+
+Creates a filter function which could filter an array of paths with `Array.prototype.filter`.
+
+Returns `function(path)` the filter function.
+
+## `options.ignorecase` since 4.0.0
+
+Similar as the `core.ignorecase` option of [git-config](https://git-scm.com/docs/git-config), `node-ignore` will be case insensitive if `options.ignorecase` is set to `true` (default value), otherwise case sensitive.
+
+```js
+const ig = ignore({
+  ignorecase: false
+})
+
+ig.add('*.png')
+
+ig.ignores('*.PNG')  // false
+```
+
+****
+
+# Upgrade Guide
+
+## Upgrade 2.x -> 3.x
+
+- All `options` of 2.x are unnecessary and removed, so just remove them.
+- `ignore()` instance is no longer an [`EventEmitter`](nodejs.org/api/events.html), and all events are unnecessary and removed.
+- `.addIgnoreFile()` is removed, see the [.addIgnoreFile](#addignorefilepath) section for details.
+
+## Upgrade 3.x -> 4.x
+
+Since `4.0.0`, `ignore` will no longer support node < 6, to use `ignore` in node < 6:
+
+```js
+var ignore = require('ignore/legacy')
+```

+	"unicorn": /* ❤ */ "cake"
+}`;
+
+JSON.parse(stripJsonComments(json));
+//=> {unicorn: 'cake'}
+```
+
+## API
+
