-> A neat wrapper around node.js fs.watch / fs.watchFile / fsevents.
-
-[![NPM](https://nodei.co/npm-dl/chokidar.png)](https://nodei.co/npm/chokidar/)
-[![NPM](https://nodei.co/npm/chokidar.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/chokidar/)
-
-## Why?
-Node.js `fs.watch`:
-
-* Doesn't report filenames on OS X.
-* Doesn't report events at all when using editors like Sublime on OS X.
-* Often reports events twice.
-* Emits most changes as `rename`.
-* Has [a lot of other issues](https://github.com/joyent/node/search?q=fs.watch&type=Issues)
-* Does not provide an easy way to recursively watch file trees.
-
-Node.js `fs.watchFile`:
-
-* Almost as bad at event handling.
-* Also does not provide any recursive watching.
-* Results in high CPU utilization.
-
-Chokidar resolves these problems.
-
-Initially made for [brunch](http://brunch.io) (an ultra-swift web app build tool), it is now used in
-[gulp](https://github.com/gulpjs/gulp/),
-[karma](http://karma-runner.github.io),
-[PM2](https://github.com/Unitech/PM2),
-[browserify](http://browserify.org/),
-[webpack](http://webpack.github.io/),
-[BrowserSync](http://www.browsersync.io/),
-[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode),
-and [many others](https://www.npmjs.org/browse/depended/chokidar/).
-It has proven itself in production environments.
-
-## How?
-Chokidar does still rely on the Node.js core `fs` module, but when using
-`fs.watch` and `fs.watchFile` for watching, it normalizes the events it
-receives, often checking for truth by getting file stats and/or dir contents.
-
-On Mac OS X, chokidar by default uses a native extension exposing the Darwin
-`FSEvents` API. This provides very efficient recursive watching compared with
-implementations like `kqueue` available on most \*nix platforms. Chokidar still
-does have to do some work to normalize the events received that way as well.
-
-On other platforms, the `fs.watch`-based implementation is the default, which
-avoids polling and keeps CPU usage down. Be advised that chokidar will initiate
-watchers recursively for everything within scope of the paths that have been
-specified, so be judicious about not wasting system resources by watching much
-more than needed.
-
-## Getting started
-Install with npm:
-
-    npm install chokidar --save
-
-Then `require` and use it in your code:
-
-```javascript
-var chokidar = require('chokidar');
-
-// One-liner for current directory, ignores .dotfiles
-chokidar.watch('.', {ignored: /(^|[\/\\])\../}).on('all', (event, path) => {
-  console.log(event, path);
-});
-```
-
-```javascript
-// Example of a more typical implementation structure:
-
-// Initialize watcher.
-var watcher = chokidar.watch('file, dir, glob, or array', {
-  ignored: /(^|[\/\\])\../,
-  persistent: true
-});
-
-// Something to use when events are received.
-var log = console.log.bind(console);
-// Add event listeners.
-watcher
-  .on('add', path => log(`File ${path} has been added`))
-  .on('change', path => log(`File ${path} has been changed`))
-  .on('unlink', path => log(`File ${path} has been removed`));
-
-// More possible events.
-watcher
-  .on('addDir', path => log(`Directory ${path} has been added`))
-  .on('unlinkDir', path => log(`Directory ${path} has been removed`))
-  .on('error', error => log(`Watcher error: ${error}`))
-  .on('ready', () => log('Initial scan complete. Ready for changes'))
-  .on('raw', (event, path, details) => {
-    log('Raw event info:', event, path, details);
-  });
-
-// 'add', 'addDir' and 'change' events also receive stat() results as second
-// argument when available: http://nodejs.org/api/fs.html#fs_class_fs_stats
-watcher.on('change', (path, stats) => {
-  if (stats) console.log(`File ${path} changed size to ${stats.size}`);
-});
-
-// Watch new files.
-watcher.add('new-file');
-watcher.add(['new-file-2', 'new-file-3', '**/other-file*']);
-
-// Get list of actual paths being watched on the filesystem
-var watchedPaths = watcher.getWatched();
-
-// Un-watch some files.
-watcher.unwatch('new-file*');
-
-// Stop watching.
-watcher.close();
-
-// Full list of options. See below for descriptions. (do not use this example)
-chokidar.watch('file', {
-  persistent: true,
-
-  ignored: '*.txt',
-  ignoreInitial: false,
-  followSymlinks: true,
-  cwd: '.',
-  disableGlobbing: false,
-
-  usePolling: true,
-  interval: 100,
-  binaryInterval: 300,
-  alwaysStat: false,
-  depth: 99,
-  awaitWriteFinish: {
-    stabilityThreshold: 2000,
-    pollInterval: 100
-  },
-
-  ignorePermissionErrors: false,
-  atomic: true // or a custom 'atomicity delay', in milliseconds (default 100)
-});
-
-```
-
-## API
-
-`chokidar.watch(paths, [options])`
-
-* `paths` (string or array of strings). Paths to files, dirs to be watched
-recursively, or glob patterns.
-* `options` (object) Options object as defined below:
-
-#### Persistence
-
-* `persistent` (default: `true`). Indicates whether the process
-should continue to run as long as files are being watched. If set to
-`false` when using `fsevents` to watch, no more events will be emitted
-after `ready`, even if the process continues to run.
-
-#### Path filtering
-
-* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition)
-Defines files/paths to be ignored. The whole relative or absolute path is
-tested, not just filename. If a function with two arguments is provided, it
-gets called twice per path - once with a single argument (the path), second
-time with two arguments (the path and the
-[`fs.Stats`](http://nodejs.org/api/fs.html#fs_class_fs_stats)
-object of that path).
-* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while
-instantiating the watching as chokidar discovers these file paths (before the `ready` event).
-* `followSymlinks` (default: `true`). When `false`, only the
-symlinks themselves will be watched for changes instead of following
-the link references and bubbling events through the link's path.
-* `cwd` (no default). The base directory from which watch `paths` are to be
-derived. Paths emitted with events will be relative to this.
-* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as
-literal path names, even if they look like globs.
-
-#### Performance
-
-* `usePolling` (default: `false`).
-Whether to use fs.watchFile (backed by polling), or fs.watch. If polling
-leads to high CPU utilization, consider setting this to `false`. It is
-typically necessary to **set this to `true` to successfully watch files over
-a network**, and it may be necessary to successfully watch files in other
-non-standard situations. Setting to `true` explicitly on OS X overrides the
-`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable
-to true (1) or false (0) in order to override this option.
-* _Polling-specific settings_ (effective when `usePolling: true`)
-  * `interval` (default: `100`). Interval of file system polling. You may also 
-    set the CHOKIDAR_INTERVAL env variable to override this option.
-  * `binaryInterval` (default: `300`). Interval of file system
-  polling for binary files.
-  ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json))
-* `useFsEvents` (default: `true` on OS X). Whether to use the
-`fsevents` watching interface if available. When set to `true` explicitly
-and `fsevents` is available this supercedes the `usePolling` setting. When
-set to `false` on OS X, `usePolling: true` becomes the default.
-* `alwaysStat` (default: `false`). If relying upon the
-[`fs.Stats`](http://nodejs.org/api/fs.html#fs_class_fs_stats)
-object that may get passed with `add`, `addDir`, and `change` events, set
-this to `true` to ensure it is provided even in cases where it wasn't
-already available from the underlying watch events.
-* `depth` (default: `undefined`). If set, limits how many levels of
-subdirectories will be traversed.
-* `awaitWriteFinish` (default: `false`).
-By default, the `add` event will fire when a file first appears on disk, before
-the entire file has been written. Furthermore, in some cases some `change`
-events will be emitted while the file is being written. In some cases,
-especially when watching for large files there will be a need to wait for the
-write operation to finish before responding to a file creation or modification.
-Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size,
-holding its `add` and `change` events until the size does not change for a
-configurable amount of time. The appropriate duration setting is heavily
-dependent on the OS and hardware. For accurate detection this parameter should
-be relatively high, making file watching much less responsive.
-Use with caution.
-  * *`options.awaitWriteFinish` can be set to an object in order to adjust
-  timing params:*
-  * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in
-  milliseconds for a file size to remain constant before emitting its event.
-  * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval.
-
-#### Errors
-* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files
-that don't have read permissions if possible. If watching fails due to `EPERM`
-or `EACCES` with this set to `true`, the errors will be suppressed silently.
-* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`).
-Automatically filters out artifacts that occur when using editors that use
-"atomic writes" instead of writing directly to the source file. If a file is
-re-added within 100 ms of being deleted, Chokidar emits a `change` event
-rather than `unlink` then `add`. If the default of 100 ms does not work well
-for you, you can override it by setting `atomic` to a custom value, in
-milliseconds.
-
-### Methods & Events
-
-`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`:
-
-* `.add(path / paths)`: Add files, directories, or glob patterns for tracking.
-Takes an array of strings or just one string.
-* `.on(event, callback)`: Listen for an FS event.
-Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`,
-`raw`, `error`.
-Additionally `all` is available which gets emitted with the underlying event
-name and path for every event other than `ready`, `raw`, and `error`.
-* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns.
-Takes an array of strings or just one string.
-* `.close()`: Removes all listeners from watched files.
-* `.getWatched()`: Returns an object representing all the paths on the file
-system being watched by this `FSWatcher` instance. The object's keys are all the
-directories (using absolute paths unless the `cwd` option was used), and the
-values are arrays of the names of the items contained in each directory.
-
-## CLI
-
-If you need a CLI interface for your file watching, check out
-[chokidar-cli](https://github.com/kimmobrunfeldt/chokidar-cli), allowing you to
-execute a command on each change, or get a stdio stream of change events.
-
-## Install Troubleshooting

-* `npm WARN optional dep failed, continuing fsevents@n.n.n`
-  * This message is normal part of how `npm` handles optional dependencies and is
-    not indicative of a problem. Even if accompanied by other related error messages,
-    Chokidar should function properly.
-
-* `ERR! stack Error: Python executable "python" is v3.4.1, which is not supported by gyp.`
-  * You should be able to resolve this by installing python 2.7 and running:
-    `npm config set python python2.7`
-
-* `gyp ERR! stack Error: not found: make`
-  * On Mac, install the XCode command-line tools
