+
+Module for verifying whether an object has been garbage collected or not.
+
+Internally creates a weak reference to the object, and forces garbage collection
+to happen. If the reference is gone, it meant no one else was pointing to the
+object.
+
+## Example
+
+```javascript
+let reference = {};
+
+const detector = new LeakDetector(reference);
+
+// Reference is held in memory.
+console.log(detector.isLeaked()); // true
+
+// We destroy the only reference to the object.
+reference = null;
+
+// Reference is gone.
+console.log(detector.isLeaked()); // false
+```

+
+> Regular expression for matching [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code)
+
+
+## Install
+
+```
+$ npm install ansi-regex
+```
+
+
+## Usage
+
+```js
+const ansiRegex = require('ansi-regex');
+
+ansiRegex().test('\u001B[4mcake\u001B[0m');
+//=> true
+
+ansiRegex().test('cake');
+//=> false
+
+'\u001B[4mcake\u001B[0m'.match(ansiRegex());
+//=> ['\u001B[4m', '\u001B[0m']
+```
+
+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.

+
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+
+## Installation
+
+```sh
+$ yarn add pretty-format
+```
+
+## Usage
+
+```js
+const prettyFormat = require('pretty-format'); // CommonJS
+```
+
+```js
+import prettyFormat from 'pretty-format'; // ES2015 modules
+```
+
+```js
+const val = {object: {}};
+val.circularReference = val;
+val[Symbol('foo')] = 'foo';
+val.map = new Map([['prop', 'value']]);
+val.array = [-0, Infinity, NaN];
+
+console.log(prettyFormat(val));
+/*
+Object {
+  "array": Array [
+    -0,
+    Infinity,
+    NaN,
+  ],
+  "circularReference": [Circular],
+  "map": Map {
+    "prop" => "value",
+  },
+  "object": Object {},
+  Symbol(foo): "foo",
+}
+*/
+```
+
+## Usage with options
+
+```js
+function onClick() {}
+
+console.log(prettyFormat(onClick));
+/*
+[Function onClick]
+*/
+
+const options = {
+  printFunctionName: false,
+};
+console.log(prettyFormat(onClick, options));
+/*
+[Function]
+*/
+```

+
+Property values of `theme` are from
+[ansi-styles colors](https://github.com/chalk/ansi-styles#colors)
+
+```js
+const DEFAULT_THEME = {
+  comment: 'gray',
+  content: 'reset',
+  prop: 'yellow',
+  tag: 'cyan',
+  value: 'green',
+};
+```
+
+## Usage with plugins
+
+The `pretty-format` package provides some built-in plugins, including:
+
+* `ReactElement` for elements from `react`
+* `ReactTestComponent` for test objects from `react-test-renderer`
+
+```js
+// CommonJS
+const prettyFormat = require('pretty-format');
+const ReactElement = prettyFormat.plugins.ReactElement;
+const ReactTestComponent = prettyFormat.plugins.ReactTestComponent;
+
+const React = require('react');
+const renderer = require('react-test-renderer');
+```
+
+```js
+// ES2015 modules and destructuring assignment
+import prettyFormat from 'pretty-format';
+const {ReactElement, ReactTestComponent} = prettyFormat.plugins;
+
+import React from 'react';
+import renderer from 'react-test-renderer';
+```
+
+```js
+const onClick = () => {};
+const element = React.createElement('button', {onClick}, 'Hello World');
+
+const formatted1 = prettyFormat(element, {
+  plugins: [ReactElement],
+  printFunctionName: false,
+});
+const formatted2 = prettyFormat(renderer.create(element).toJSON(), {
+  plugins: [ReactTestComponent],
+  printFunctionName: false,
+});
+/*
+<button
+  onClick=[Function]
+>
+  Hello World
+</button>
+*/
+```
+
+## Usage in Jest
+
+For snapshot tests, Jest uses `pretty-format` with options that include some of
+its built-in plugins. For this purpose, plugins are also known as **snapshot
+serializers**.
+
+To serialize application-specific data types, you can add modules to
+`devDependencies` of a project, and then:
+
+In an **individual** test file, you can add a module as follows. It precedes any
+modules from Jest configuration.
+
+```js
+import serializer from 'my-serializer-module';
+expect.addSnapshotSerializer(serializer);
+
+// tests which have `expect(value).toMatchSnapshot()` assertions
+```
+
+For **all** test files, you can specify modules in Jest configuration. They
+precede built-in plugins for React, HTML, and Immutable.js data types. For
+example, in a `package.json` file:
+
+```json
+{
+  "jest": {
+    "snapshotSerializers": ["my-serializer-module"]
+  }
+}
+```
+
+## Writing plugins
+
+A plugin is a JavaScript object.
+
+If `options` has a `plugins` array: for the first plugin whose `test(val)`
+method returns a truthy value, then `prettyFormat(val, options)` returns the
+result from either:
+
+* `serialize(val, …)` method of the **improved** interface (available in
+  **version 21** or later)
+* `print(val, …)` method of the **original** interface (if plugin does not have
+  `serialize` method)
+
+### test
+
+Write `test` so it can receive `val` argument of any type. To serialize
+**objects** which have certain properties, then a guarded expression like
+`val != null && …` or more concise `val && …` prevents the following errors:
+
+* `TypeError: Cannot read property 'whatever' of null`
+* `TypeError: Cannot read property 'whatever' of undefined`
+
+For example, `test` method of built-in `ReactElement` plugin:
+
+```js
+const elementSymbol = Symbol.for('react.element');
+const test = val => val && val.$$typeof === elementSymbol;
+```
+
+Pay attention to efficiency in `test` because `pretty-format` calls it often.
+
+### serialize
+
+The **improved** interface is available in **version 21** or later.
+
+Write `serialize` to return a string, given the arguments:
+
+* `val` which “passed the test”
+* unchanging `config` object: derived from `options`
+* current `indentation` string: concatenate to `indent` from `config`
+* current `depth` number: compare to `maxDepth` from `config`
+* current `refs` array: find circular references in objects
+* `printer` callback function: serialize children
+
+### config
+
+| key                 | type      | description                                             |
+| :------------------ | :-------- | :------------------------------------------------------ |
+| `callToJSON`        | `boolean` | call `toJSON` method (if it exists) on objects          |
+| `colors`            | `Object`  | escape codes for colors to highlight syntax             |
+| `escapeRegex`       | `boolean` | escape special characters in regular expressions        |
+| `indent`            | `string`  | spaces in each level of indentation                     |
+| `maxDepth`          | `number`  | levels to print in arrays, objects, elements, and so on |
+| `min`               | `boolean` | minimize added space: no indentation nor line breaks    |
+| `plugins`           | `array`   | plugins to serialize application-specific data types    |
+| `printFunctionName` | `boolean` | include or omit the name of a function                  |
+| `spacingInner`      | `strong`  | spacing to separate items in a list                     |
+| `spacingOuter`      | `strong`  | spacing to enclose a list of items                      |
+
+Each property of `colors` in `config` corresponds to a property of `theme` in
+`options`:
+
+* the key is the same (for example, `tag`)
+* the value in `colors` is a object with `open` and `close` properties whose
+  values are escape codes from
+  [ansi-styles](https://github.com/chalk/ansi-styles) for the color value in
+  `theme` (for example, `'cyan'`)
+
+Some properties in `config` are derived from `min` in `options`:
+
+* `spacingInner` and `spacingOuter` are **newline** if `min` is `false`
+* `spacingInner` is **space** and `spacingOuter` is **empty string** if `min` is
+  `true`
+
+### Example of serialize and test
+
+This plugin is a pattern you can apply to serialize composite data types. Of
+course, `pretty-format` does not need a plugin to serialize arrays :)
+
+```js
+// We reused more code when we factored out a function for child items
+// that is independent of depth, name, and enclosing punctuation (see below).
+const SEPARATOR = ',';
+function serializeItems(items, config, indentation, depth, refs, printer) {
+  if (items.length === 0) {
+    return '';
+  }
+  const indentationItems = indentation + config.indent;
+  return (
+    config.spacingOuter +
+    items
+      .map(
+        item =>
+          indentationItems +
+          printer(item, config, indentationItems, depth, refs), // callback
+      )
+      .join(SEPARATOR + config.spacingInner) +
+    (config.min ? '' : SEPARATOR) + // following the last item
+    config.spacingOuter +
+    indentation
+  );
+}
+
+const plugin = {
+  test(val) {
+    return Array.isArray(val);
+  },
+  serialize(array, config, indentation, depth, refs, printer) {
+    const name = array.constructor.name;
+    return ++depth > config.maxDepth
+      ? '[' + name + ']'
+      : (config.min ? '' : name + ' ') +
+          '[' +
+          serializeItems(array, config, indentation, depth, refs, printer) +
+          ']';
+  },
+};
+```
+
+```js
+const val = {
+  filter: 'completed',
+  items: [
+    {
+      text: 'Write test',
+      completed: true,
+    },
+    {
+      text: 'Write serialize',
+      completed: true,
+    },
+  ],
+};
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+  "filter": "completed",
+  "items": Array [
+    Object {
+      "completed": true,
+      "text": "Write test",
+    },
+    Object {
+      "completed": true,
+      "text": "Write serialize",
+    },
+  ],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    indent: 4,
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+    "filter": "completed",
+    "items": Array [
+        Object {
+            "completed": true,
+            "text": "Write test",
+        },
+        Object {
+            "completed": true,
+            "text": "Write serialize",
+        },
+    ],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    maxDepth: 1,
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+  "filter": "completed",
+  "items": [Array],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    min: true,
+    plugins: [plugin],
+  }),
+);
+/*
+{"filter": "completed", "items": [{"completed": true, "text": "Write test"}, {"completed": true, "text": "Write serialize"}]}
+*/
+```
+
+### print
+
+The **original** interface is adequate for plugins:
+
+* that **do not** depend on options other than `highlight` or `min`
+* that **do not** depend on `depth` or `refs` in recursive traversal, and
+* if values either
+  * do **not** require indentation, or
+  * do **not** occur as children of JavaScript data structures (for example,
+    array)
+
+Write `print` to return a string, given the arguments:
+
+* `val` which “passed the test”
+* current `printer(valChild)` callback function: serialize children
+* current `indenter(lines)` callback function: indent lines at the next level
+* unchanging `config` object: derived from `options`
+* unchanging `colors` object: derived from `options`
+
+The 3 properties of `config` are `min` in `options` and:
+
+* `spacing` and `edgeSpacing` are **newline** if `min` is `false`
+* `spacing` is **space** and `edgeSpacing` is **empty string** if `min` is
+  `true`
+
+Each property of `colors` corresponds to a property of `theme` in `options`:
+
+* the key is the same (for example, `tag`)
+* the value in `colors` is a object with `open` and `close` properties whose
+  values are escape codes from
+  [ansi-styles](https://github.com/chalk/ansi-styles) for the color value in
+  `theme` (for example, `'cyan'`)
+
+### Example of print and test
+
+This plugin prints functions with the **number of named arguments** excluding
+rest argument.
+
+```js
+const plugin = {
+  print(val) {
+    return `[Function ${val.name || 'anonymous'} ${val.length}]`;
+  },
+  test(val) {
+    return typeof val === 'function';
+  },
+};
+```
+
+```js
+const val = {
+  onClick(event) {},
+  render() {},
+};
+
+prettyFormat(val, {
+  plugins: [plugin],
+});
+/*
+Object {
+  "onClick": [Function onClick 1],
+  "render": [Function render 0],
+}
+*/
+
+prettyFormat(val);
+/*
+Object {
+  "onClick": [Function onClick],
+  "render": [Function render],
+}
+*/
+```
+
+This plugin **ignores** the `printFunctionName` option. That limitation of the
+original `print` interface is a reason to use the improved `serialize`
+interface, described above.
+
+```js
+prettyFormat(val, {
+  plugins: [pluginOld],
+  printFunctionName: false,
+});
+/*
+Object {
+  "onClick": [Function onClick 1],
+  "render": [Function render 0],
+}
+*/
+
+prettyFormat(val, {
+  printFunctionName: false,
+});
+/*
+Object {
+  "onClick": [Function],
+  "render": [Function],
+}
+*/
+```
