-# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
-
-> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
-
-You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
-
-<img src="https://cdn.rawgit.com/chalk/ansi-styles/8261697c95bf34b6c7767e2cbe9941a851d59385/screenshot.svg" width="900">
-
-
-## Install
-
-```
-$ npm install ansi-styles
-```
-
-
-## 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.
-
-
-## Styles
-
-### Modifiers
-
-- `reset`
-- `bold`
-- `dim`
-- `italic` *(Not widely supported)*
-- `underline`
-- `inverse`
-- `hidden`
-- `strikethrough` *(Not widely supported)*
-
-### Colors
-
-- `black`
-- `red`
-- `green`
-- `yellow`
-- `blue`
-- `magenta`
-- `cyan`
-- `white`
-- `gray` ("bright black")
-- `redBright`
-- `greenBright`
-- `yellowBright`
-- `blueBright`
-- `magentaBright`
-- `cyanBright`
-- `whiteBright`
-
-### Background colors
-
-- `bgBlack`
-- `bgRed`
-- `bgGreen`
-- `bgYellow`
-- `bgBlue`
-- `bgMagenta`
-- `bgCyan`
-- `bgWhite`
-- `bgBlackBright`
-- `bgRedBright`
-- `bgGreenBright`
-- `bgYellowBright`
-- `bgBlueBright`
-- `bgMagentaBright`
-- `bgCyanBright`
-- `bgWhiteBright`
-
-
-## 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
-```

-
-
-## Usage
-
-```js
-const chalk = require('chalk');
-
-console.log(chalk.blue('Hello world!'));
-```
-
-Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
-
-```js
-const chalk = require('chalk');
-const log = console.log;
-
-// Combine styled and normal strings
-log(chalk.blue('Hello') + ' World' + chalk.red('!'));
-
-// Compose multiple styles using the chainable API
-log(chalk.blue.bgRed.bold('Hello world!'));
-
-// Pass in multiple arguments
-log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
-
-// Nest styles
-log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
-
-// Nest styles of the same type even (color, underline, background)
-log(chalk.green(
-	'I am a green line ' +
-	chalk.blue.underline.bold('with a blue substring') +
-	' that becomes green again!'
-));
-
-// ES2015 template literal
-log(`
-CPU: ${chalk.red('90%')}
-RAM: ${chalk.green('40%')}
-DISK: ${chalk.yellow('70%')}
-`);
-
-// ES2015 tagged template literal
-log(chalk`
-CPU: {red ${cpu.totalPercent}%}
-RAM: {green ${ram.used / ram.total * 100}%}
-DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
-`);
-
-// Use RGB colors in terminal emulators that support it.
-log(chalk.keyword('orange')('Yay for orange colored text!'));
-log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
-log(chalk.hex('#DEADED').bold('Bold gray!'));
-```
-
-Easily define your own themes:
-
-```js
-const chalk = require('chalk');
-
-const error = chalk.bold.red;
-const warning = chalk.keyword('orange');
-
-console.log(error('Error!'));
-console.log(warning('Warning!'));
-```
-
-Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
-
-```js
-const name = 'Sindre';
-console.log(chalk.green('Hello %s'), name);
-//=> 'Hello Sindre'
-```
-
-
-## API
-
-### chalk.`<style>[.<style>...](string, [string...])`
-
-Example: `chalk.red.bold.underline('Hello', 'world');`
-
-Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
-
-Multiple arguments will be separated by space.
-
-### chalk.enabled
-
-Color support is automatically detected, as is the level (see `chalk.level`). However, if you'd like to simply enable/disable Chalk, you can do so via the `.enabled` property.
-
-Chalk is enabled by default unless explicitly disabled via the constructor or `chalk.level` is `0`.
-
-If you need to change this in a reusable module, create a new instance:
-
-```js
-const ctx = new chalk.constructor({enabled: false});
-```
-
-### chalk.level
-
-Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
-
-If you need to change this in a reusable module, create a new instance:
-
-```js
-const ctx = new chalk.constructor({level: 0});
-```
-
-Levels are as follows:
-
-0. All colors disabled
-1. Basic color support (16 colors)
-2. 256 color support
-3. Truecolor support (16 million colors)
-
-### chalk.supportsColor
-
-Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
-
-Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` 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.

-
-## Tagged template literal
-
-Chalk can be used as a [tagged template literal](http://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
-
-```js
-const chalk = require('chalk');
-
-const miles = 18;
-const calculateFeet = miles => miles * 5280;
-
-console.log(chalk`
-  There are {bold 5280 feet} in a mile.
-  In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
-`);
-```
-
-Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
-
-Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
-
-```js
-console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
-console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
-```
-
-Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
-
-All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
-
-
-## 256 and Truecolor color support
-
-Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
-
-Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
-
-Examples:
-
-- `chalk.hex('#DEADED').underline('Hello, world!')`
-- `chalk.keyword('orange')('Some orange text')`
-- `chalk.rgb(15, 100, 204).inverse('Hello!')`
-
-Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
-
-- `chalk.bgHex('#DEADED').underline('Hello, world!')`
-- `chalk.bgKeyword('orange')('Some orange text')`
-- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
-
-The following color models can be used:
-
-- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
-- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
-- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
-- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
-- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
-- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model)  - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
-- `ansi16`
-- `ansi256`
-
-
-## Windows
-
-If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`.
-
-
-## Origin story
-
-[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

-# color-convert
-
-[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
-
-Color-convert is a color conversion library for JavaScript and node.
-It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
-
-```js
-var convert = require('color-convert');
-
-convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
-convert.keyword.rgb('blue');                // [0, 0, 255]
-
-var rgbChannels = convert.rgb.channels;     // 3
-var cmykChannels = convert.cmyk.channels;   // 4
-var ansiChannels = convert.ansi16.channels; // 1
-```
-
-# Install
-
-```console
-$ npm install color-convert
-```
-
-# API
-
-Simply get the property of the _from_ and _to_ conversion that you're looking for.
-
-All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
-
-All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
-
-```js
-var convert = require('color-convert');
-
-// Hex to LAB
-convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
-convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
-
-// RGB to CMYK
-convert.rgb.cmyk(167, 255, 4);     // [ 35, 0, 98, 0 ]
-convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
-```
-
-### Arrays
-All functions that accept multiple arguments also support passing an array.
-
-Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
-
-```js
-var convert = require('color-convert');
-
-convert.rgb.hex(123, 45, 67);      // '7B2D43'
-convert.rgb.hex([123, 45, 67]);    // '7B2D43'
-```
-
-## Routing
-
-Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
-
-Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).

-# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
-
-> Detect whether a terminal supports color
-
-
-## Install
-
-```
-$ npm install supports-color
-```
-
-
-## Usage
-
-```js
-const supportsColor = require('supports-color');
-
-if (supportsColor.stdout) {
-	console.log('Terminal stdout supports color');
-}
-
-if (supportsColor.stdout.has256) {
-	console.log('Terminal stdout supports 256 colors');
-}
-
-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.
-
-Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` 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.

+/**
+ * @fileoverview The factory of `ConfigArray` objects.
+ *
+ * This class provides methods to create `ConfigArray` instance.
+ *
+ * - `create(configData, options)`
+ *     Create a `ConfigArray` instance from a config data. This is to handle CLI
+ *     options except `--config`.
+ * - `loadFile(filePath, options)`
+ *     Create a `ConfigArray` instance from a config file. This is to handle
+ *     `--config` option. If the file was not found, throws the following error:
+ *      - If the filename was `*.js`, a `MODULE_NOT_FOUND` error.
+ *      - If the filename was `package.json`, an IO error or an
+ *        `ESLINT_CONFIG_FIELD_NOT_FOUND` error.
+ *      - Otherwise, an IO error such as `ENOENT`.
+ * - `loadInDirectory(directoryPath, options)`
+ *     Create a `ConfigArray` instance from a config file which is on a given
+ *     directory. This tries to load `.eslintrc.*` or `package.json`. If not
+ *     found, returns an empty `ConfigArray`.
+ * - `loadESLintIgnore(filePath)`
+ *     Create a `ConfigArray` instance from a config file that is `.eslintignore`
+ *     format. This is to handle `--ignore-path` option.
+ * - `loadDefaultESLintIgnore()`
+ *     Create a `ConfigArray` instance from `.eslintignore` or `package.json` in
+ *     the current working directory.
+ *
+ * `ConfigArrayFactory` class has the responsibility that loads configuration
+ * files, including loading `extends`, `parser`, and `plugins`. The created
+ * `ConfigArray` instance has the loaded `extends`, `parser`, and `plugins`.
+ *
+ * But this class doesn't handle cascading. `CascadingConfigArrayFactory` class
+ * handles cascading and hierarchy.

+argparse
+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.svg?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
+  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
+  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
+  `SUPPRESS`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({parameters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supported yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+JS-YAML - YAML 1.2 parser / writer for JavaScript
+=================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+__[Online Demo](http://nodeca.github.com/js-yaml/)__
+
+
+This is an implementation of [YAML](http://yaml.org/), a human-friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for the online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resources to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+const yaml = require('js-yaml');
+const fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  const doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns either a
+plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does
+not support regexps, functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will call this function with an instance of `YAMLException` for each warning.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, the JSON schema is not as strictly defined in the YAML specification.
+It allows numbers in any notation, use `Null` and `NULL` as `null`, etc.
+The core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you
+must additionally validate object structure to avoid injections:
+
+``` javascript
+const untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string [, iterator] [, options ])
+
+Same as `safeLoad()`, but understands multi-document sources. Applies
+`iterator` to each document if specified, or returns array of documents.
+
+``` javascript
+const yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string [, iterator] [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw an exception if you try to dump regexps or functions. However, you can
+disable exceptions by setting the `skipInvalid` option to `true`.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a
+  function, use the function to sort the keys.
+- `lineWidth` _(default: `80`)_ - set max line width.
+- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references
+- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older
+  yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1
+- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded.
+
+The following table show availlable styles (e.g. "canonical",
+"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml
+output is shown on the right side after `=>` (default setting) or `->`:
+
+``` none
+!!null
+  "canonical"   -> "~"
+  "lowercase"   => "null"
+  "uppercase"   -> "NULL"
+  "camelcase"   -> "Null"
+
+!!int
+  "binary"      -> "0b1", "0b101010", "0b1110001111010"
+  "octal"       -> "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
+
+!!bool
+  "lowercase"   => "true", "false"
+  "uppercase"   -> "TRUE", "FALSE"
+  "camelcase"   -> "True", "False"
+
+!!float
+  "lowercase"   => ".nan", '.inf'
+  "uppercase"   -> ".NAN", '.INF'
+  "camelcase"   -> ".NaN", '.Inf'
+```
+
+Example:
+
+``` javascript
+safeDump (object, {
+  'styles': {
+    '!!null': 'canonical' // dump null as ~
+  },
+  'sortKeys': true        // sort object keys
+});
+```
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
+or arrays as keys, and stringifies (by calling `toString()` method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```

 The `normalize()` method returns a promise, so be sure to use the `await` operator. The config array instance is normalized in-place, so you don't need to create a new variable.
 
+If you want to disallow async config functions, you can call `normalizeSync()` instead. This method is completely synchronous and does not require using the `await` operator as it does not return a promise:
+
+```js
+await configs.normalizeSync({
+    name: "MyApp"
+});

 **Important:** Once a `ConfigArray` is normalized, it cannot be changed further. You can, however, create a new `ConfigArray` and pass in the normalized instance to create an unnormalized copy.

+  // - Check duplicate argument names, if checkClashes is set.
+  //
+  // If a complex binding pattern is encountered (e.g., object and array
+  // destructuring), the entire pattern is recursively checked.
+  //
+  // There are three versions of checkLVal*() appropriate for different
+  // circumstances:
+  //
+  // - checkLValSimple() shall be used if the syntactic construct supports
+  //   nothing other than identifiers and member expressions. Parenthesized

+  //   constructs for which the spec says
+  //
+  //   > It is a Syntax Error if AssignmentTargetType of [the production] is not
+  //   > simple.
+  //
+  //   It is also appropriate for checking if an identifier is valid and not
+  //   defined elsewhere, like import declarations or function/class identifiers.
+  //
+  //   Examples where this is used include:
+  //     a += …;
+  //     import a from '…';
+  //   where a is the node to be checked.
+  //
+  // - checkLValPattern() shall be used if the syntactic construct supports
+  //   anything checkLValSimple() supports, as well as object and array
+  //   destructuring patterns. This is generally appropriate for constructs for
+  //   which the spec says
+  //
+  //   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
+  //   > an ArrayLiteral and AssignmentTargetType of [the production] is not
+  //   > simple.
+  //
+  //   Examples where this is used include:
+  //     (a = …);
+  //     const a = …;
+  //     try { … } catch (a) { … }
+  //   where a is the node to be checked.
+  //
+  // - checkLValInnerPattern() shall be used if the syntactic construct supports
+  //   anything checkLValPattern() supports, as well as default assignment
+  //   patterns, rest elements, and other constructs that may appear within an
+  //   object or array destructuring pattern.
+  //
+  //   As a special case, function parameters also use checkLValInnerPattern(),
+  //   as they also support defaults and rest constructs.
+  //
+  // These functions deliberately support both assignment and binding constructs,
+  // as the logic for both is exceedingly similar. If the node is the target of
+  // an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
+  // should be set to the appropriate BIND_* constant, like BIND_VAR or

-// Verify that a node is an lval — something that can be assigned

-// 'var' indicating that the lval creates a 'var' binding
-// 'let' indicating that the lval creates a lexical ('let' or 'const') binding
-// 'none' indicating that the binding should be checked for illegal identifiers, but not for duplicate references
+// The following three functions all verify that a node is an lvalue —
+// something that can be bound, or assigned to. In order to do so, they perform
+// a variety of checks:
+//
+// - Check that none of the bound/assigned-to identifiers are reserved words.
+// - Record name declarations for bindings in the appropriate scope.
+// - Check duplicate argument names, if checkClashes is set.
+//
+// If a complex binding pattern is encountered (e.g., object and array
+// destructuring), the entire pattern is recursively checked.
+//
+// There are three versions of checkLVal*() appropriate for different
+// circumstances:
+//
+// - checkLValSimple() shall be used if the syntactic construct supports
+//   nothing other than identifiers and member expressions. Parenthesized
+//   expressions are also correctly handled. This is generally appropriate for
+//   constructs for which the spec says
+//
+//   > It is a Syntax Error if AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   It is also appropriate for checking if an identifier is valid and not
+//   defined elsewhere, like import declarations or function/class identifiers.
+//
+//   Examples where this is used include:
+//     a += …;
+//     import a from '…';
+//   where a is the node to be checked.
+//
+// - checkLValPattern() shall be used if the syntactic construct supports
+//   anything checkLValSimple() supports, as well as object and array
+//   destructuring patterns. This is generally appropriate for constructs for
+//   which the spec says
+//
+//   > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
+//   > an ArrayLiteral and AssignmentTargetType of [the production] is not
+//   > simple.
+//
+//   Examples where this is used include:
+//     (a = …);
+//     const a = …;
+//     try { … } catch (a) { … }
+//   where a is the node to be checked.
+//
+// - checkLValInnerPattern() shall be used if the syntactic construct supports
+//   anything checkLValPattern() supports, as well as default assignment
+//   patterns, rest elements, and other constructs that may appear within an
+//   object or array destructuring pattern.
+//
+//   As a special case, function parameters also use checkLValInnerPattern(),
+//   as they also support defaults and rest constructs.
+//
+// These functions deliberately support both assignment and binding constructs,
+// as the logic for both is exceedingly similar. If the node is the target of
+// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
+// should be set to the appropriate BIND_* constant, like BIND_VAR or
+// BIND_LEXICAL.
+//
+// If the function is called with a non-BIND_NONE bindingType, then
+// additionally a checkClashes object may be specified to allow checking for
+// duplicate argument names. checkClashes is ignored if the provided construct
+// is an assignment (i.e., bindingType is BIND_NONE).

-ArgumentParser objects
-======================
-
-```
-new ArgumentParser({parameters hash});
-```
-
-Creates a new ArgumentParser object.
-
-**Supported params:**
-
-- ```description``` - Text to display before the argument help.
-- ```epilog``` - Text to display after the argument help.
-- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
-- ```argumentDefault``` - Set the global default value for arguments. (default: null)
-- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
-- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
-- ```formatterClass``` - A class for customizing the help output.
-- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
-- ```usage``` - The string describing the program usage (default: generated)
-- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
-
-**Not supported yet**
-
-- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
-
-
-Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
-
-
-addArgument() method
-====================
-
-```
-ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
-```
-
-Defines how a single command-line argument should be parsed.
-
-- ```name or flag or [name] or [flags...]``` - Either a positional name
-  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
-  of a single positional name (e.g., `['foo']`), or an array of options
-  (e.g., `['-f', '--foo']`).
-
-Options:
-
-- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
-- ```nargs```- The number of command-line arguments that should be consumed.
-- ```constant``` - A constant value required by some action and nargs selections.
-- ```defaultValue``` - The value produced if the argument is absent from the command line.
-- ```type``` - The type to which the command-line argument should be converted.
-- ```choices``` - A container of the allowable values for the argument.
-- ```required``` - Whether or not the command-line option may be omitted (optionals only).
-- ```help``` - A brief description of what the argument does.
-- ```metavar``` - A name for the argument in usage messages.
-- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
-
-Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
-
-
-Action (some details)
-================
-
-ArgumentParser objects associate command-line arguments with actions.
-These actions can do just about anything with the command-line arguments associated
-with them, though most actions simply add an attribute to the object returned by
-parseArgs(). The action keyword argument specifies how the command-line arguments
-should be handled. The supported actions are:
-
-- ```store``` - Just stores the argument’s value. This is the default action.
-- ```storeConst``` - Stores value, specified by the const keyword argument.
-  (Note that the const keyword argument defaults to the rather unhelpful None.)
-  The 'storeConst' action is most commonly used with optional arguments, that
-  specify some sort of flag.
-- ```storeTrue``` and ```storeFalse``` - Stores values True and False
-  respectively. These are special cases of 'storeConst'.
-- ```append``` - Stores a list, and appends each argument value to the list.
-  This is useful to allow an option to be specified multiple times.
-- ```appendConst``` - Stores a list, and appends value, specified by the
-  const keyword argument to the list. (Note, that the const keyword argument defaults
-  is None.) The 'appendConst' action is typically used when multiple arguments need
-  to store constants to the same list.
-- ```count``` - Counts the number of times a keyword argument occurs. For example,
-  used for increasing verbosity levels.
-- ```help``` - Prints a complete help message for all the options in the current
-  parser and then exits. By default a help action is automatically added to the parser.
-  See ArgumentParser for details of how the output is created.
-- ```version``` - Prints version information and exit. Expects a `version=`
-  keyword argument in the addArgument() call.
-
-Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
-
-
-Sub-commands
-============
-
-ArgumentParser.addSubparsers()
-
-Many programs split their functionality into a number of sub-commands, for
-example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
-and `svn commit`. Splitting up functionality this way can be a particularly good
-idea when a program performs several different functions which require different
-kinds of command-line arguments. `ArgumentParser` supports creation of such
-sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
-normally called with no arguments and returns an special action object.
-This object has a single method `addParser()`, which takes a command name and
-any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
-that can be modified as usual.
-
-Example:
-
-sub_commands.js
-```javascript
-#!/usr/bin/env node
-'use strict';
-
-var ArgumentParser = require('../lib/argparse').ArgumentParser;
-var parser = new ArgumentParser({
-  version: '0.0.1',
-  addHelp:true,
-  description: 'Argparse examples: sub-commands',
-});
-
-var subparsers = parser.addSubparsers({
-  title:'subcommands',
-  dest:"subcommand_name"
-});
-
-var bar = subparsers.addParser('c1', {addHelp:true});
-bar.addArgument(
-  [ '-f', '--foo' ],
-  {
-    action: 'store',
-    help: 'foo3 bar3'
-  }
-);
-var bar = subparsers.addParser(
-  'c2',
-  {aliases:['co'], addHelp:true}
-);
-bar.addArgument(
-  [ '-b', '--bar' ],
-  {
-    action: 'store',
-    type: 'int',
-    help: 'foo3 bar3'
-  }
-);
-
-var args = parser.parseArgs();
-console.dir(args);
-
-```

+/*
+ * Command-line parsing library
+ *
+ * This module is an optparse-inspired command-line parsing library that:
+ *
+ *     - handles both optional and positional arguments
+ *     - produces highly informative usage messages
+ *     - supports parsers that dispatch to sub-parsers
+ *
+ * The following is a simple usage example that sums integers from the
+ * command-line and writes the result to a file::
+ *
+ *     parser = argparse.ArgumentParser(
+ *         description='sum the integers at the command line')
+ *     parser.add_argument(
+ *         'integers', metavar='int', nargs='+', type=int,
+ *         help='an integer to be summed')
+ *     parser.add_argument(
+ *         '--log', default=sys.stdout, type=argparse.FileType('w'),
+ *         help='the file where the sum should be written')
+ *     args = parser.parse_args()
+ *     args.log.write('%s' % sum(args.integers))
+ *     args.log.close()
+ *
+ * The module contains the following public classes:
+ *
+ *     - ArgumentParser -- The main entry point for command-line parsing. As the
+ *         example above shows, the add_argument() method is used to populate
+ *         the parser with actions for optional and positional arguments. Then
+ *         the parse_args() method is invoked to convert the args at the
+ *         command-line into an object with attributes.
+ *
+ *     - ArgumentError -- The exception raised by ArgumentParser objects when
+ *         there are errors with the parser's actions. Errors raised while
+ *         parsing the command-line are caught by ArgumentParser and emitted
+ *         as command-line messages.
+ *
+ *     - FileType -- A factory for defining types of files to be created. As the
+ *         example above shows, instances of FileType are typically passed as
+ *         the type= argument of add_argument() calls.
+ *
+ *     - Action -- The base class for parser actions. Typically actions are
+ *         selected by passing strings like 'store_true' or 'append_const' to
+ *         the action= argument of add_argument(). However, for greater
+ *         customization of ArgumentParser actions, subclasses of Action may
+ *         be defined and passed as the action= argument.
+ *
+ *     - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
+ *         ArgumentDefaultsHelpFormatter -- Formatter classes which
+ *         may be passed as the formatter_class= argument to the
+ *         ArgumentParser constructor. HelpFormatter is the default,
+ *         RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
+ *         not to change the formatting for help text, and
+ *         ArgumentDefaultsHelpFormatter adds information about argument defaults
+ *         to the help.
+ *
+ * All other classes in this module are considered implementation details.
+ * (Also note that HelpFormatter and RawDescriptionHelpFormatter are only
+ * considered public as object names -- the API of the formatter objects is
+ * still considered an implementation detail.)

+     *          with the default, a single value will be produced, while with
+     *          nargs=1, a list containing a single value will be produced.
+     *
+     *      - const -- The value to be produced if the option is specified and the

+     *
+     *      - default -- The value to be produced if the option is not specified.

+     *          returns the converted value.  The standard Python types str, int,
+     *          float, and complex are useful examples of such callables.  If None,
+     *          str is used.
+     *

+     *  the wrap() and fill() methods; the other methods are just there for
+     *  subclasses to override in order to tweak the default behaviour.
+     *  If you want to completely replace the main wrapping algorithm,
+     *  you'll probably have to override _wrap_chunks().
+     *
+     *  Several instance attributes control various aspects of wrapping:
+     *    width (default: 70)
+     *      the maximum width of wrapped lines (unless break_long_words
+     *      is false)
+     *    initial_indent (default: "")
+     *      string that will be prepended to the first line of wrapped
+     *      output.  Counts towards the line's width.
+     *    subsequent_indent (default: "")
+     *      string that will be prepended to all lines save the first
+     *      of wrapped output; also counts towards each line's width.
+     *    expand_tabs (default: true)
+     *      Expand tabs in input text to spaces before further processing.
+     *      Each tab will become 0 .. 'tabsize' spaces, depending on its position
+     *      in its line.  If false, each tab is treated as a single character.
+     *    tabsize (default: 8)
+     *      Expand tabs in input text to 0 .. 'tabsize' spaces, unless
+     *      'expand_tabs' is false.
+     *    replace_whitespace (default: true)
+     *      Replace all whitespace characters in the input text by spaces
+     *      after tab expansion.  Note that if expand_tabs is false and
+     *      replace_whitespace is true, every tab will be converted to a
+     *      single space!
+     *    fix_sentence_endings (default: false)
+     *      Ensure that sentence-ending punctuation is always followed
+     *      by two spaces.  Off by default because the algorithm is
+     *      (unavoidably) imperfect.
+     *    break_long_words (default: true)
+     *      Break words longer than 'width'.  If false, those words will not
+     *      be broken, and some lines might be longer than 'width'.
+     *    break_on_hyphens (default: true)
+     *      Allow breaking hyphenated words. If true, wrapping will occur
+     *      preferably on whitespaces and right after hyphens part of
+     *      compound words.
+     *    drop_whitespace (default: true)
+     *      Drop leading and trailing whitespace from lines.
+     *    max_lines (default: None)
+     *      Truncate wrapped lines.

-# emoji-regex [![Build status](https://travis-ci.org/mathiasbynens/emoji-regex.svg?branch=master)](https://travis-ci.org/mathiasbynens/emoji-regex)
-
-_emoji-regex_ offers a regular expression to match all emoji symbols (including textual representations of emoji) as per the Unicode Standard.
-
-This repository contains a script that generates this regular expression based on [the data from Unicode v12](https://github.com/mathiasbynens/unicode-12.0.0). Because of this, the regular expression can easily be updated whenever new emoji are added to the Unicode standard.
-
-## Installation
-
-Via [npm](https://www.npmjs.com/):
-
-```bash
-npm install emoji-regex
-```
-
-In [Node.js](https://nodejs.org/):
-
-```js
-const emojiRegex = require('emoji-regex');
-// Note: because the regular expression has the global flag set, this module
-// exports a function that returns the regex rather than exporting the regular
-// expression itself, to make it impossible to (accidentally) mutate the
-// original regular expression.
-
-const text = `
-\u{231A}: ⌚ default emoji presentation character (Emoji_Presentation)
-\u{2194}\u{FE0F}: ↔️ default text presentation character rendered as emoji
-\u{1F469}: 👩 emoji modifier base (Emoji_Modifier_Base)
-\u{1F469}\u{1F3FF}: 👩🏿 emoji modifier base followed by a modifier
-`;
-
-const regex = emojiRegex();
-let match;
-while (match = regex.exec(text)) {
-  const emoji = match[0];
-  console.log(`Matched sequence ${ emoji } — code points: ${ [...emoji].length }`);
-}
-```
-
-Console output:
-
-```
-Matched sequence ⌚ — code points: 1
-Matched sequence ⌚ — code points: 1
-Matched sequence ↔️ — code points: 2
-Matched sequence ↔️ — code points: 2
-Matched sequence 👩 — code points: 1
-Matched sequence 👩 — code points: 1
-Matched sequence 👩🏿 — code points: 2
-Matched sequence 👩🏿 — code points: 2
-```
-
-To match emoji in their textual representation as well (i.e. emoji that are not `Emoji_Presentation` symbols and that aren’t forced to render as emoji by a variation selector), `require` the other regex:
-
-```js
-const emojiRegex = require('emoji-regex/text.js');
-```
-
-Additionally, in environments which support ES2015 Unicode escapes, you may `require` ES2015-style versions of the regexes:
-
-```js
-const emojiRegex = require('emoji-regex/es2015/index.js');
-const emojiRegexText = require('emoji-regex/es2015/text.js');
-```

 ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
 
-## Usage
-
-Install:
+## Install
 
 ```
 npm i eslint-scope --save
 ```
 
+## 📖 Usage
+
+To use in an ESM file:
+
+```js
+import * as eslintScope from 'eslint-scope';
+```
+
+To use in a CommonJS file:
+
+```js
+const eslintScope = require('eslint-scope');
+```
+
 Example:
 
 ```js
-var eslintScope = require('eslint-scope');
-var espree = require('espree');
-var estraverse = require('estraverse');
+import * as eslintScope from 'eslint-scope';
+import * as espree from 'espree';
+import estraverse from 'estraverse';
 
-var ast = espree.parse(code);
-var scopeManager = eslintScope.analyze(ast);
+const ast = espree.parse(code, { range: true });
+const scopeManager = eslintScope.analyze(ast);
 
-var currentScope = scopeManager.acquire(ast);   // global scope
+const currentScope = scopeManager.acquire(ast);   // global scope
 
 estraverse.traverse(ast, {
-    enter: function(node, parent) {
+    enter (node, parent) {
         // do stuff
 
         if (/Function/.test(node.type)) {
             currentScope = scopeManager.acquire(node);  // get current function scope
         }
     },
-    leave: function(node, parent) {
+    leave(node, parent) {
         if (/Function/.test(node.type)) {
             currentScope = currentScope.upper;  // set to parent scope
         }

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:

-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      negligent acts) or agreed to in writing, shall any Contributor be

-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the

-
-Constants and utilities about visitor keys to traverse AST.
-
-## 💿 Installation
-
-Use [npm] to install.
-
-```bash
-$ npm install eslint-visitor-keys
-```
-
-### Requirements
-
-- [Node.js] 4.0.0 or later.
-
-## 📖 Usage
-
-```js
-const evk = require("eslint-visitor-keys")
-```
-
-### evk.KEYS
-
-> type: `{ [type: string]: string[] | undefined }`
-
-Visitor keys. This keys are frozen.
-
-This is an object. Keys are the type of [ESTree] nodes. Their values are an array of property names which have child nodes.
-
-For example:
-
-```
-console.log(evk.KEYS.AssignmentExpression) // → ["left", "right"]
-```
-
-### evk.getKeys(node)
-
-> type: `(node: object) => string[]`
-
-Get the visitor keys of a given AST node.
-
-This is similar to `Object.keys(node)` of ES Standard, but some keys are excluded: `parent`, `leadingComments`, `trailingComments`, and names which start with `_`.
-
-This will be used to traverse unknown nodes.
-
-For example:
-
-```
-const node = {
-    type: "AssignmentExpression",
-    left: { type: "Identifier", name: "foo" },
-    right: { type: "Literal", value: 0 }
-}
-console.log(evk.getKeys(node)) // → ["type", "left", "right"]
-```
-
-### evk.unionWith(additionalKeys)
-
-> type: `(additionalKeys: object) => { [type: string]: string[] | undefined }`
-
-Make the union set with `evk.KEYS` and the given keys.
-
-- The order of keys is, `additionalKeys` is at first, then `evk.KEYS` is concatenated after that.
-- It removes duplicated keys as keeping the first one.
-
-For example:
-
-```
-console.log(evk.unionWith({
-    MethodDefinition: ["decorators"]
-})) // → { ..., MethodDefinition: ["decorators", "key", "value"], ... }
-```
-
-## 📰 Change log
-
-See [GitHub releases](https://github.com/eslint/eslint-visitor-keys/releases).
-
-## 🍻 Contributing
-
-Welcome. See [ESLint contribution guidelines](https://eslint.org/docs/developer-guide/contributing/).
-
-### Development commands
-
-- `npm test` runs tests and measures code coverage.
-- `npm run lint` checks source codes with ESLint.
-- `npm run coverage` opens the code coverage report of the previous test with your default browser.
-- `npm run release` publishes this package to [npm] registory.

-### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.svg)](http://travis-ci.org/estools/estraverse)
-
-Estraverse ([estraverse](http://github.com/estools/estraverse)) is
-[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
-traversal functions from [esmangle project](http://github.com/estools/esmangle).
-
-### Documentation
-
-You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
-
-### Example Usage
-
-The following code will output all variables declared at the root of a file.
-
-```javascript
-estraverse.traverse(ast, {
-    enter: function (node, parent) {
-        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
-            return estraverse.VisitorOption.Skip;
-    },
-    leave: function (node, parent) {
-        if (node.type == 'VariableDeclarator')
-          console.log(node.id.name);
-    }
-});
-```
-
-We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
-
-```javascript
-estraverse.traverse(ast, {
-    enter: function (node) {
-        this.break();
-    }
-});
-```
-
-And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
-
-```javascript
-result = estraverse.replace(tree, {
-    enter: function (node) {
-        // Replace it with replaced.
-        if (node.type === 'Literal')
-            return replaced;
-    }
-});
-```
-
-By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
-
-```javascript
-// This tree contains a user-defined `TestExpression` node.
-var tree = {
-    type: 'TestExpression',
-
-    // This 'argument' is the property containing the other **node**.
-    argument: {
-        type: 'Literal',
-        value: 20
-    },
-
-    // This 'extended' is the property not containing the other **node**.
-    extended: true
-};
-estraverse.traverse(tree, {
-    enter: function (node) { },
-
-    // Extending the existing traversing rules.
-    keys: {
-        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
-        TestExpression: ['argument']
-    }
-});
-```
-
-By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
-
-```javascript
-// This tree contains a user-defined `TestExpression` node.
-var tree = {
-    type: 'TestExpression',
-
-    // This 'argument' is the property containing the other **node**.
-    argument: {
-        type: 'Literal',
-        value: 20
-    },
-
-    // This 'extended' is the property not containing the other **node**.
-    extended: true
-};
-estraverse.traverse(tree, {
-    enter: function (node) { },
-
-    // Iterating the child **nodes** of unknown nodes.
-    fallback: 'iteration'
-});
-```
-
-When `visitor.fallback` is a function, we can determine which keys to visit on each node.
-
-```javascript
-// This tree contains a user-defined `TestExpression` node.
-var tree = {
-    type: 'TestExpression',
-
-    // This 'argument' is the property containing the other **node**.
-    argument: {
-        type: 'Literal',
-        value: 20
-    },
-
-    // This 'extended' is the property not containing the other **node**.
-    extended: true
-};
-estraverse.traverse(tree, {
-    enter: function (node) { },
-
-    // Skip the `argument` property of each node
-    fallback: function(node) {
-        return Object.keys(node).filter(function(key) {
-            return key !== 'argument';
-        });
-    }
-});
-```

-### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.svg)](http://travis-ci.org/estools/estraverse)
-
-Estraverse ([estraverse](http://github.com/estools/estraverse)) is
-[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
-traversal functions from [esmangle project](http://github.com/estools/esmangle).
-
-### Documentation
-
-You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
-
-### Example Usage
-
-The following code will output all variables declared at the root of a file.
-
-```javascript
-estraverse.traverse(ast, {
-    enter: function (node, parent) {
-        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
-            return estraverse.VisitorOption.Skip;
-    },
-    leave: function (node, parent) {
-        if (node.type == 'VariableDeclarator')
-          console.log(node.id.name);
-    }
-});
-```
-
-We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
-
-```javascript
-estraverse.traverse(ast, {
-    enter: function (node) {
-        this.break();
-    }
-});
-```
-
-And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
-
-```javascript
-result = estraverse.replace(tree, {
-    enter: function (node) {
-        // Replace it with replaced.
-        if (node.type === 'Literal')
-            return replaced;
-    }
-});
-```
-
-By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
-
-```javascript
-// This tree contains a user-defined `TestExpression` node.
-var tree = {
-    type: 'TestExpression',
-
-    // This 'argument' is the property containing the other **node**.
-    argument: {
-        type: 'Literal',
-        value: 20
-    },
-
-    // This 'extended' is the property not containing the other **node**.
-    extended: true
-};
-estraverse.traverse(tree, {
-    enter: function (node) { },
-
-    // Extending the existing traversing rules.
-    keys: {
-        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
-        TestExpression: ['argument']
-    }
-});
-```
-
-By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
-
-```javascript
-// This tree contains a user-defined `TestExpression` node.
-var tree = {
-    type: 'TestExpression',
-
-    // This 'argument' is the property containing the other **node**.
-    argument: {
-        type: 'Literal',
-        value: 20
-    },
-
-    // This 'extended' is the property not containing the other **node**.
-    extended: true
-};
-estraverse.traverse(tree, {
-    enter: function (node) { },
-
-    // Iterating the child **nodes** of unknown nodes.
-    fallback: 'iteration'
-});
-```
-
-When `visitor.fallback` is a function, we can determine which keys to visit on each node.
-
-```javascript
-// This tree contains a user-defined `TestExpression` node.
-var tree = {
-    type: 'TestExpression',
-
-    // This 'argument' is the property containing the other **node**.
-    argument: {
-        type: 'Literal',
-        value: 20
-    },
-
-    // This 'extended' is the property not containing the other **node**.
-    extended: true
-};
-estraverse.traverse(tree, {
-    enter: function (node) { },
-
-    // Skip the `argument` property of each node
-    fallback: function(node) {
-        return Object.keys(node).filter(function(key) {
-            return key !== 'argument';
-        });
-    }
-});
-```

-Overview [![Build Status](https://travis-ci.org/lydell/js-tokens.svg?branch=master)](https://travis-ci.org/lydell/js-tokens)
-========
-
-A regex that tokenizes JavaScript.
-
-```js
-var jsTokens = require("js-tokens").default
-
-var jsString = "var foo=opts.foo;\n..."
-
-jsString.match(jsTokens)
-// ["var", " ", "foo", "=", "opts", ".", "foo", ";", "\n", ...]
-```
-
-
-Installation
-============
-
-`npm install js-tokens`
-
-```js
-import jsTokens from "js-tokens"
-// or:
-var jsTokens = require("js-tokens").default
-```
-
-
-Usage
-=====
-
-### `jsTokens` ###
-
-A regex with the `g` flag that matches JavaScript tokens.
-
-The regex _always_ matches, even invalid JavaScript and the empty string.
-
-The next match is always directly after the previous.
-
-### `var token = matchToToken(match)` ###
-
-```js
-import {matchToToken} from "js-tokens"
-// or:
-var matchToToken = require("js-tokens").matchToToken
-```
-
-Takes a `match` returned by `jsTokens.exec(string)`, and returns a `{type:
-String, value: String}` object. The following types are available:
-
-- string
-- comment
-- regex
-- number
-- name
-- punctuator
-- whitespace
-- invalid
-
-Multi-line comments and strings also have a `closed` property indicating if the
-token was closed or not (see below).
-
-Comments and strings both come in several flavors. To distinguish them, check if
-the token starts with `//`, `/*`, `'`, `"` or `` ` ``.
-
-Names are ECMAScript IdentifierNames, that is, including both identifiers and
-keywords. You may use [is-keyword-js] to tell them apart.
-
-Whitespace includes both line terminators and other whitespace.
-
-[is-keyword-js]: https://github.com/crissdev/is-keyword-js
-
-
-ECMAScript support
-==================
-
-The intention is to always support the latest ECMAScript version whose feature
-set has been finalized.
-
-If adding support for a newer version requires changes, a new version with a
-major verion bump will be released.
-
-Currently, ECMAScript 2018 is supported.
-
-
-Invalid code handling
-=====================
-
-Unterminated strings are still matched as strings. JavaScript strings cannot
-contain (unescaped) newlines, so unterminated strings simply end at the end of
-the line. Unterminated template strings can contain unescaped newlines, though,
-so they go on to the end of input.
-
-Unterminated multi-line comments are also still matched as comments. They
-simply go on to the end of the input.
-
-Unterminated regex literals are likely matched as division and whatever is
-inside the regex.
-
-Invalid ASCII characters have their own capturing group.
-
-Invalid non-ASCII characters are treated as names, to simplify the matching of
-names (except unicode spaces which are treated as whitespace). Note: See also
-the [ES2018](#es2018) section.
-
-Regex literals may contain invalid regex syntax. They are still matched as
-regex literals. They may also contain repeated regex flags, to keep the regex
-simple.
-
-Strings may contain invalid escape sequences.
-
-
-Limitations
-===========
-
-Tokenizing JavaScript using regexes—in fact, _one single regex_—won’t be
-perfect. But that’s not the point either.
-
-You may compare jsTokens with [esprima] by using `esprima-compare.js`.
-See `npm run esprima-compare`!
-
-[esprima]: http://esprima.org/
-
-### Template string interpolation ###
-
-Template strings are matched as single tokens, from the starting `` ` `` to the
-ending `` ` ``, including interpolations (whose tokens are not matched
-individually).
-
-Matching template string interpolations requires recursive balancing of `{` and
-`}`—something that JavaScript regexes cannot do. Only one level of nesting is
-supported.
-
-### Division and regex literals collision ###
-
-Consider this example:
-
-```js
-var g = 9.82
-var number = bar / 2/g
-
-var regex = / 2/g
-```
-
-A human can easily understand that in the `number` line we’re dealing with
-division, and in the `regex` line we’re dealing with a regex literal. How come?
-Because humans can look at the whole code to put the `/` characters in context.
-A JavaScript regex cannot. It only sees forwards. (Well, ES2018 regexes can also
-look backwards. See the [ES2018](#es2018) section).
-
-When the `jsTokens` regex scans throught the above, it will see the following
-at the end of both the `number` and `regex` rows:
-
-```js
-/ 2/g
-```
-
-It is then impossible to know if that is a regex literal, or part of an
-expression dealing with division.
-
-Here is a similar case:
-
-```js
-foo /= 2/g
-foo(/= 2/g)
-```
-
-The first line divides the `foo` variable with `2/g`. The second line calls the
-`foo` function with the regex literal `/= 2/g`. Again, since `jsTokens` only
-sees forwards, it cannot tell the two cases apart.
-
-There are some cases where we _can_ tell division and regex literals apart,
-though.
-
-First off, we have the simple cases where there’s only one slash in the line:
-
-```js
-var foo = 2/g
-foo /= 2
-```
-
-Regex literals cannot contain newlines, so the above cases are correctly
-identified as division. Things are only problematic when there are more than
-one non-comment slash in a single line.
-
-Secondly, not every character is a valid regex flag.
-
-```js
-var number = bar / 2/e
-```
-
-The above example is also correctly identified as division, because `e` is not a
-valid regex flag. I initially wanted to future-proof by allowing `[a-zA-Z]*`
-(any letter) as flags, but it is not worth it since it increases the amount of
-ambigous cases. So only the standard `g`, `m`, `i`, `y` and `u` flags are
-allowed. This means that the above example will be identified as division as
-long as you don’t rename the `e` variable to some permutation of `gmiyus` 1 to 6
-characters long.
-
-Lastly, we can look _forward_ for information.
-
-- If the token following what looks like a regex literal is not valid after a
-  regex literal, but is valid in a division expression, then the regex literal
-  is treated as division instead. For example, a flagless regex cannot be
-  followed by a string, number or name, but all of those three can be the
-  denominator of a division.
-- Generally, if what looks like a regex literal is followed by an operator, the
-  regex literal is treated as division instead. This is because regexes are
-  seldomly used with operators (such as `+`, `*`, `&&` and `==`), but division
-  could likely be part of such an expression.
-
-Please consult the regex source and the test cases for precise information on
-when regex or division is matched (should you need to know). In short, you
-could sum it up as:
-
-If the end of a statement looks like a regex literal (even if it isn’t), it
-will be treated as one. Otherwise it should work as expected (if you write sane
-code).
-
-### ES2018 ###
-
-ES2018 added some nice regex improvements to the language.
-
-- [Unicode property escapes] should allow telling names and invalid non-ASCII
-  characters apart without blowing up the regex size.
-- [Lookbehind assertions] should allow matching telling division and regex
-  literals apart in more cases.
-- [Named capture groups] might simplify some things.
-
-These things would be nice to do, but are not critical. They probably have to
-wait until the oldest maintained Node.js LTS release supports those features.

-# string-width
-
-> Get the visual width of a string - the number of columns required to display it
-
-Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
-
-Useful to be able to measure the actual width of command-line output.
-
-
-## Install
-
-```
-$ npm install string-width
-```
-
-
-## Usage
-
-```js
-const stringWidth = require('string-width');
-
-stringWidth('a');
-//=> 1
-
-stringWidth('古');
-//=> 2
-
-stringWidth('\u001B[1m古\u001B[22m');
-//=> 2

-### createStream
-
-`table` package exports `createStream` function used to draw a table and append rows.
-
-**Parameter:**
- - _**config:**_ the same as `table`'s, except `config.columnDefault.width` and `config.columnCount` must be provided.
-
-
-```js
-import { createStream } from 'table';
-
-const config = {
-  columnDefault: {
-    width: 50
-  },
-  columnCount: 1
-};
-
-const stream = createStream(config);
-
-setInterval(() => {
-  stream.write([new Date()]);
-}, 500);
-```
-
-![Streaming current date.](./.README/api/stream/streaming.gif)
-
-`table` package uses ANSI escape codes to overwrite the output of the last line when a new row is printed.
-
-The underlying implementation is explained in this [Stack Overflow answer](http://stackoverflow.com/a/32938658/368691).
-
-Streaming supports all of the configuration properties and functionality of a static table (such as auto text wrapping, alignment and padding), e.g.
-
-```js
-import { createStream } from 'table';
-
-import _ from 'lodash';
-
-const config = {
-  columnDefault: {
-    width: 50
-  },
-  columnCount: 3,
-  columns: [
-    {
-      width: 10,
-      alignment: 'right'
-    },
-    { alignment: 'center' },
-    { width: 10 }
-
-  ]
-};
-
-const stream = createStream(config);
-
-let i = 0;
-
-setInterval(() => {
-  let random;
-
-  random = _.sample('abcdefghijklmnopqrstuvwxyz', _.random(1, 30)).join('');
-

-#### Borderless Table
-
-Simply using `void` border character template creates a table with a lot of unnecessary spacing.
-
-To create a more pleasant to the eye table, reset the padding and remove the joining rows, e.g.
-
-```js
-
-const output = table(data, {
-    border: getBorderCharacters('void'),
-    columnDefault: {
-        paddingLeft: 0,
-        paddingRight: 1
-    },
-    drawHorizontalLine: () => false
-    }
-);
-
-console.log(output);
-```

-## Performance
-
-Ajv generates code to turn JSON Schemas into super-fast validation functions that are efficient for v8 optimization.
-
-Currently Ajv is the fastest and the most standard compliant validator according to these benchmarks:
-
-- [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark) - 50% faster than the second place
-- [jsck benchmark](https://github.com/pandastrike/jsck#benchmarks) - 20-190% faster
-- [z-schema benchmark](https://rawgit.com/zaggino/z-schema/master/benchmark/results.html)
-- [themis benchmark](https://cdn.rawgit.com/playlyfe/themis/master/benchmark/results.html)
-
-Performance of different validators by [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark):

-## Install
-
-```
-npm install json-schema-traverse
-```
-
-
-## Usage
-
-```javascript
-const traverse = require('json-schema-traverse');
-const schema = {
-  properties: {
-    foo: {type: 'string'},
-    bar: {type: 'integer'}
-  }
-};
-
-traverse(schema, {cb});
-// cb is called 3 times with:
-// 1. root schema
-// 2. {type: 'string'}
-// 3. {type: 'integer'}
-
-// Or:
-
-traverse(schema, {cb: {pre, post}});
-// pre is called 3 times with:
-// 1. root schema
-// 2. {type: 'string'}
-// 3. {type: 'integer'}
-//
-// post is called 3 times with:
-// 1. {type: 'string'}
-// 2. {type: 'integer'}
-// 3. root schema
-
-```
-
-Callback function `cb` is called for each schema object (not including draft-06 boolean schemas), including the root schema, in pre-order traversal. Schema references ($ref) are not resolved, they are passed as is.  Alternatively, you can pass a `{pre, post}` object as `cb`, and then `pre` will be called before traversing child elements, and `post` will be called after all child elements have been traversed.
-
-Callback is passed these parameters:
-
-- _schema_: the current schema object
-- _JSON pointer_: from the root schema to the current schema object
-- _root schema_: the schema passed to `traverse` object
-- _parent JSON pointer_: from the root schema to the parent schema object (see below)
-- _parent keyword_: the keyword inside which this schema appears (e.g. `properties`, `anyOf`, etc.)
-- _parent schema_: not necessarily parent object/array; in the example above the parent schema for `{type: 'string'}` is the root schema
-- _index/property_: index or property name in the array/object containing multiple schemas; in the example above for `{type: 'string'}` the property name is `'foo'`

-## Traverse objects in all unknown keywords
-
-```javascript
-const traverse = require('json-schema-traverse');
-const schema = {
-  mySchema: {
-    minimum: 1,
-    maximum: 2
-  }
-};
-
-traverse(schema, {allKeys: true, cb});
-// cb is called 2 times with:
-// 1. root schema
-// 2. mySchema
-```
-
-Without option `allKeys: true` callback will be called only with root schema.
-
-
