+// The following TSLint rules have been disabled:
+// unified-signatures: Because there is useful information in the argument names of the overloaded signatures
+
+// Convention:
+// Use 'union types' when:
+//  - parameter types have similar signature type (i.e. 'string | ReadonlyArray<string>')
+//  - parameter names have the same semantic meaning (i.e. ['command', 'commands'] , ['key', 'keys'])
+//    An example for not using 'union types' is the declaration of 'env' where `prefix` and `enable` parameters
+//    have different semantics. On the other hand, in the declaration of 'usage', a `command: string` parameter
+//    has the same semantic meaning with declaring an overload method by using `commands: ReadonlyArray<string>`,
+//    thus it's preferred to use `command: string | ReadonlyArray<string>`
+// Use parameterless declaration instead of declaring all parameters optional,
+// when all parameters are optional and more than one

+
+> [ANSI escape codes](https://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="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`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `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.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `keyword`
+- `hsl`
+- `hsv`
+- `hwb`
+- `ansi`
+- `ansi256`
+
+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
+```

+
+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~46,000 packages](https://www.npmjs.com/browse/depended/chalk) as of October 1, 2019
+
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+
+## 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.level
+
+Specifies the level of color support.
+
+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.Instance({level: 0});
+```
+
+| Level | Description |
+| :---: | :--- |
+| `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, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+### chalk.stderr and chalk.stderr.supportsColor
+
+`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
+
+
+## Styles
+
+### Modifiers
+
+- `reset` - Resets the current color chain.
+- `bold` - Make text bold.
+- `dim` - Emitting only a small amount of light.
+- `italic` - Make text italic. *(Not widely supported)*
+- `underline` - Make text underline. *(Not widely supported)*
+- `inverse`- Inverse background and foreground colors.
+- `hidden` - Prints the text, but makes it invisible.
+- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
+- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+
+## 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!')`
+- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
+- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`

+## Windows
+
+If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) 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.
+
+
+## chalk for enterprise
+
+Available as part of the Tidelift Subscription.
+
+The maintainers of chalk and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use.

+# 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).
+
+# Contribute
+
+If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero element in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
+  are equal.  Sorts in ascending order if passed to `Array.sort()`.
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version, options)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Integer.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).
+
+If the `options.rtl` flag is set, then `coerce` will return the right-most
+coercible tuple that does not share an ending index with a longer coercible
+tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
+`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
+any other overlapping SemVer tuple.
+
+### Clean
+
+* `clean(version)`: Clean a string to be a valid semver if possible
+
+This will return a cleaned and trimmed semver version. If the provided version is not valid a null will be returned. This does not work for ranges. 
+
+ex.
+* `s.clean(' = v 2.1.5foo')`: `null`
+* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean(' = v 2.1.5-foo')`: `null`
+* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean('=v2.1.5')`: `'2.1.5'`
+* `s.clean('  =v2.1.5')`: `2.1.5`
+* `s.clean('      2.1.5   ')`: `'2.1.5'`
+* `s.clean('~1.0.0')`: `null`

+# 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.
+
+For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
