+/**
+ * HasteMap is a JavaScript implementation of Facebook's haste module system.
+ *
+ * This implementation is inspired by https://github.com/facebook/node-haste
+ * and was built with for high-performance in large code repositories with
+ * hundreds of thousands of files. This implementation is scalable and provides
+ * predictable performance.
+ *
+ * Because the haste map creation and synchronization is critical to startup
+ * performance and most tasks are blocked by I/O this class makes heavy use of
+ * synchronous operations. It uses worker processes for parallelizing file
+ * access and metadata extraction.
+ *
+ * The data structures created by `jest-haste-map` can be used directly from the
+ * cache without further processing. The metadata objects in the `files` and
+ * `map` objects contain cross-references: a metadata object from one can look
+ * up the corresponding metadata object in the other map. Note that in most
+ * projects, the number of files will be greater than the number of haste
+ * modules one module can refer to many files based on platform extensions.
+ *
+ * type HasteMap = {
+ *   clocks: WatchmanClocks,
+ *   files: {[filepath: string]: FileMetaData},
+ *   map: {[id: string]: ModuleMapItem},
+ *   mocks: {[id: string]: string},
+ * }
+ *
+ * // Watchman clocks are used for query synchronization and file system deltas.
+ * type WatchmanClocks = {[filepath: string]: string};
+ *
+ * type FileMetaData = {
+ *   id: ?string, // used to look up module metadata objects in `map`.
+ *   mtime: number, // check for outdated files.
+ *   size: number, // size of the file in bytes.
+ *   visited: boolean, // whether the file has been parsed or not.
+ *   dependencies: Array<string>, // all relative dependencies of this file.
+ *   sha1: ?string, // SHA-1 of the file, if requested via options.
+ * };
+ *
+ * // Modules can be targeted to a specific platform based on the file name.
+ * // Example: platform.ios.js and Platform.android.js will both map to the same
+ * // `Platform` module. The platform should be specified during resolution.
+ * type ModuleMapItem = {[platform: string]: ModuleMetaData};
+ *
+ * //
+ * type ModuleMetaData = {
+ *   path: string, // the path to look up the file object in `files`.
+ *   type: string, // the module type (either `package` or `module`).
+ * };
+ *
+ * Note that the data structures described above are conceptual only. The actual
+ * implementation uses arrays and constant keys for metadata storage. Instead of
+ * `{id: 'flatMap', mtime: 3421, size: 42, visited: true, dependencies: []}` the real
+ * representation is similar to `['flatMap', 3421, 42, 1, []]` to save storage space
+ * and reduce parse and write time of a big JSON blob.
+ *
+ * The HasteMap is created as follows:
+ *  1. read data from the cache or create an empty structure.
+ *
+ *  2. crawl the file system.
+ *     * empty cache: crawl the entire file system.
+ *     * cache available:
+ *       * if watchman is available: get file system delta changes.
+ *       * if watchman is unavailable: crawl the entire file system.
+ *     * build metadata objects for every file. This builds the `files` part of
+ *       the `HasteMap`.
+ *
+ *  3. parse and extract metadata from changed files.
+ *     * this is done in parallel over worker processes to improve performance.
+ *     * the worst case is to parse all files.
+ *     * the best case is no file system access and retrieving all data from
+ *       the cache.
+ *     * the average case is a small number of changed files.
+ *
+ *  4. serialize the new `HasteMap` in a cache file.
+ *     Worker processes can directly access the cache through `HasteMap.read()`.

+# jest-worker
+
+Module for executing heavy tasks under forked processes in parallel, by providing a `Promise` based interface, minimum overhead, and bound workers.
+
+The module works by providing an absolute path of the module to be loaded in all forked processes. Files relative to a node module are also accepted. All methods are exposed on the parent process as promises, so they can be `await`'ed. Child (worker) methods can either be synchronous or asynchronous.
+
+The module also implements support for bound workers. Binding a worker means that, based on certain parameters, the same task will always be executed by the same worker. The way bound workers work is by using the returned string of the `computeWorkerKey` method. If the string was used before for a task, the call will be queued to the related worker that processed the task earlier; if not, it will be executed by the first available worker, then sticked to the worker that executed it; so the next time it will be processed by the same worker. If you have no preference on the worker executing the task, but you have defined a `computeWorkerKey` method because you want _some_ of the tasks to be sticked, you can return `null` from it.
+
+The list of exposed methods can be explicitly provided via the `exposedMethods` option. If it is not provided, it will be obtained by requiring the child module into the main process, and analyzed via reflection. Check the "minimal example" section for a valid one.
+
+## Install
+
+```sh
+$ yarn add jest-worker
+```
+
+## Example
+
+This example covers the minimal usage:
+
+### File `parent.js`
+
+```javascript
+import Worker from 'jest-worker';
+
+async function main() {
+  const worker = new Worker(require.resolve('./Worker'));
+  const result = await worker.hello('Alice'); // "Hello, Alice"
+}
+
+main();
+```
+
+### File `worker.js`
+
+```javascript
+export function hello(param) {
+  return 'Hello, ' + param;
+}
+```
+
+## Experimental worker
+
+Node 10 shipped with [worker-threads](https://nodejs.org/api/worker_threads.html), a "threading API" that uses SharedArrayBuffers to communicate between the main process and its child threads. This experimental Node feature can significantly improve the communication time between parent and child processes in `jest-worker`.
+
+Since `worker_threads` are considered experimental in Node, you have to opt-in to this behavior by passing `enableWorkerThreads: true` when instantiating the worker. While the feature was unflagged in Node 11.7.0, you'll need to run the Node process with the `--experimental-worker` flag for Node 10.
+
+## API
+
+The only exposed method is a constructor (`Worker`) that is initialized by passing the worker path, plus an options object.
+
+### `workerPath: string` (required)
+
+Node module name or absolute path of the file to be loaded in the child processes. Use `require.resolve` to transform a relative path into an absolute one.
+
+### `options: Object` (optional)
+
+#### `exposedMethods: $ReadOnlyArray<string>` (optional)
+
+List of method names that can be called on the child processes from the parent process. You cannot expose any method named like a public `Worker` method, or starting with `_`. If you use method auto-discovery, then these methods will not be exposed, even if they exist.
+
+#### `numWorkers: number` (optional)
+
+Amount of workers to spawn. Defaults to the number of CPUs minus 1.
+
+#### `maxRetries: number` (optional)
+
+Maximum amount of times that a dead child can be re-spawned, per call. Defaults to `3`, pass `Infinity` to allow endless retries.
+
+#### `forkOptions: Object` (optional)
+
+Allow customizing all options passed to `childProcess.fork`. By default, some values are set (`cwd`, `env` and `execArgv`), but you can override them and customize the rest. For a list of valid values, check [the Node documentation](https://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options).
+
+#### `computeWorkerKey: (method: string, ...args: Array<any>) => ?string` (optional)
+
+Every time a method exposed via the API is called, `computeWorkerKey` is also called in order to bound the call to a worker. This is useful for workers that are able to cache the result or part of it. You bound calls to a worker by making `computeWorkerKey` return the same identifier for all different calls. If you do not want to bind the call to any worker, return `null`.
+
+The callback you provide is called with the method name, plus all the rest of the arguments of the call. Thus, you have full control to decide what to return. Check a practical example on bound workers under the "bound worker usage" section.
+
+By default, no process is bound to any worker.
+
+#### `setupArgs: Array<mixed>` (optional)
+
+The arguments that will be passed to the `setup` method during initialization.
+
+#### `workerPool: (workerPath: string, options?: WorkerPoolOptions) => WorkerPoolInterface` (optional)
+
+Provide a custom worker pool to be used for spawning child processes. By default, Jest will use a node thread pool if available and fall back to child process threads.
+
+The arguments that will be passed to the `setup` method during initialization.
+
+#### `enableWorkerThreads: boolean` (optional)
+
+`jest-worker` will automatically detect if `worker_threads` are available, but will not use them unless passed `enableWorkerThreads: true`.
+
+## Worker
+
+The returned `Worker` instance has all the exposed methods, plus some additional ones to interact with the workers itself:
+
+### `getStdout(): Readable`
+
+Returns a `ReadableStream` where the standard output of all workers is piped. Note that the `silent` option of the child workers must be set to `true` to make it work. This is the default set by `jest-worker`, but keep it in mind when overriding options through `forkOptions`.
+
+### `getStderr(): Readable`
+
+Returns a `ReadableStream` where the standard error of all workers is piped. Note that the `silent` option of the child workers must be set to `true` to make it work. This is the default set by `jest-worker`, but keep it in mind when overriding options through `forkOptions`.
+
+### `end()`
+
+Finishes the workers by killing all workers. No further calls can be done to the `Worker` instance.
+
+**Note:** Each worker has a unique id (index that starts with `1`) which is available on `process.env.JEST_WORKER_ID`
+
+## Setting up and tearing down the child process
+
+The child process can define two special methods (both of them can be asynchronous):
+
+- `setup()`: If defined, it's executed before the first call to any method in the child.
+- `teardown()`: If defined, it's executed when the farm ends.
+
+# More examples
+
+## Standard usage
+
+This example covers the standard usage:
+
+### File `parent.js`
+
+```javascript
+import Worker from 'jest-worker';
+
+async function main() {
+  const myWorker = new Worker(require.resolve('./Worker'), {
+    exposedMethods: ['foo', 'bar', 'getWorkerId'],
+    numWorkers: 4,
+  });
+
+  console.log(await myWorker.foo('Alice')); // "Hello from foo: Alice"
+  console.log(await myWorker.bar('Bob')); // "Hello from bar: Bob"
+  console.log(await myWorker.getWorkerId()); // "3" -> this message has sent from the 3rd worker
+
+  myWorker.end();
+}
+
+main();
+```
+
+### File `worker.js`
+
+```javascript
+export function foo(param) {
+  return 'Hello from foo: ' + param;
+}
+
+export function bar(param) {
+  return 'Hello from bar: ' + param;
+}
+
+export function getWorkerId() {
+  return process.env.JEST_WORKER_ID;
+}
+```
+
+## Bound worker usage:
+
+This example covers the usage with a `computeWorkerKey` method:
+
+### File `parent.js`
+
+```javascript
+import Worker from 'jest-worker';
+
+async function main() {
+  const myWorker = new Worker(require.resolve('./Worker'), {
+    computeWorkerKey: (method, filename) => filename,
+  });
+
+  // Transform the given file, within the first available worker.
+  console.log(await myWorker.transform('/tmp/foo.js'));
+
+  // Wait a bit.
+  await sleep(10000);
+
+  // Transform the same file again. Will immediately return because the
+  // transformed file is cached in the worker, and `computeWorkerKey` ensures
+  // the same worker that processed the file the first time will process it now.
+  console.log(await myWorker.transform('/tmp/foo.js'));
+
+  myWorker.end();
+}
+
+main();
+```
+
+### File `worker.js`
+
+```javascript
+import babel from '@babel/core';
+
+const cache = Object.create(null);
+
+export function transform(filename) {
+  if (cache[filename]) {
+    return cache[filename];
+  }
+
+  // jest-worker can handle both immediate results and thenables. If a
+  // thenable is returned, it will be await'ed until it resolves.
+  return babel.transformFileAsync(filename).then(result => {
+    cache[filename] = result;
+
+    return result;
+  });
+}
+```

+# merge-stream
+
+Merge (interleave) a bunch of streams.
+
+[![build status](https://secure.travis-ci.org/grncdr/merge-stream.svg?branch=master)](http://travis-ci.org/grncdr/merge-stream)
+
+## Synopsis
+
+```javascript
+var stream1 = new Stream();
+var stream2 = new Stream();
+
+var merged = mergeStream(stream1, stream2);
+
+var stream3 = new Stream();
+merged.add(stream3);
+merged.isEmpty();
+//=> false
+```
+
+## Description
+
+This is adapted from [event-stream](https://github.com/dominictarr/event-stream) separated into a new module, using Streams3.
+
+## API
+
+### `mergeStream`
+
+Type: `function`
+
+Merges an arbitrary number of streams. Returns a merged stream.
+
+#### `merged.add`
+
+A method to dynamically add more sources to the stream. The argument supplied to `add` can be either a source or an array of sources.
+
+#### `merged.isEmpty`
+
+A method that tells you if the merged stream is empty.
+
+When a stream is "empty" (aka. no sources were added), it could not be returned to a gulp task.
+
+So, we could do something like this:
+
+```js
+stream = require('merge-stream')();
+// Something like a loop to add some streams to the merge stream
+// stream.add(streamA);
+// stream.add(streamB);
+return stream.isEmpty() ? null : stream;
+```
+
+## Gulp example
+
+An example use case for **merge-stream** is to combine parts of a task in a project's **gulpfile.js** like this:
+
+```js
+const gulp =          require('gulp');
+const htmlValidator = require('gulp-w3c-html-validator');
+const jsHint =        require('gulp-jshint');
+const mergeStream =   require('merge-stream');
+
+function lint() {
+  return mergeStream(
+    gulp.src('src/*.html')
+      .pipe(htmlValidator())
+      .pipe(htmlValidator.reporter()),
+    gulp.src('src/*.js')
+      .pipe(jsHint())
+      .pipe(jsHint.reporter())
+  );
+}
+gulp.task('lint', lint);
+```

+const supportsColor = require('supports-color');
+
+if (supportsColor.stdout) {

+}
+
+if (supportsColor.stdout.has256) {

+}
+
+if (supportsColor.stderr.has16m) {
+	console.log('Terminal stderr supports 16 million colors (truecolor)');
+}
+```
+
+
+## API
+
+Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
+
+The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
+
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
+
+
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+
+## Security

+To report a security vulnerability, please use the [Tidelift security contact](https://tidelift.com/security). Tidelift will coordinate the fix and disclosure.
