# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
> [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 ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020
## 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](https://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 ${calculateFeet(miles)} feet}.
`);
```
Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
```js
console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
```
Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
All interpolated values (`` chalk`${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!')`

## 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.

# 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).

# lru cache
A cache object that deletes the least-recently-used items.
[![Build Status](https://travis-ci.org/isaacs/node-lru-cache.svg?branch=master)](https://travis-ci.org/isaacs/node-lru-cache) [![Coverage Status](https://coveralls.io/repos/isaacs/node-lru-cache/badge.svg?service=github)](https://coveralls.io/github/isaacs/node-lru-cache)
## Installation:
```javascript
npm install lru-cache --save
```
## Usage:
```javascript
var LRU = require("lru-cache")
, options = { max: 500
, length: function (n, key) { return n * 2 + key.length }
, dispose: function (key, n) { n.close() }
, maxAge: 1000 * 60 * 60 }
, cache = new LRU(options)
, otherCache = new LRU(50) // sets just the max size
cache.set("key", "value")
cache.get("key") // "value"
// non-string keys ARE fully supported
// but note that it must be THE SAME object, not
// just a JSON-equivalent object.
var someObject = { a: 1 }
cache.set(someObject, 'a value')
// Object keys are not toString()-ed
cache.set('[object Object]', 'a different value')
assert.equal(cache.get(someObject), 'a value')
// A similar object with same keys/values won't work,
// because it's a different object identity
assert.equal(cache.get({ a: 1 }), undefined)
cache.reset() // empty the cache
```
If you put more stuff in it, then items will fall out.
If you try to put an oversized thing in it, then it'll fall out right
away.
## Options
* `max` The maximum size of the cache, checked by applying the length
function to all values in the cache. Not setting this is kind of
silly, since that's the whole purpose of this lib, but it defaults
to `Infinity`. Setting it to a non-number or negative number will
throw a `TypeError`. Setting it to 0 makes it be `Infinity`.
* `maxAge` Maximum age in ms. Items are not pro-actively pruned out
as they age, but if you try to get an item that is too old, it'll
drop it and return undefined instead of giving it to you.
Setting this to a negative value will make everything seem old!
Setting it to a non-number will throw a `TypeError`.
* `length` Function that is used to calculate the length of stored
items. If you're storing strings or buffers, then you probably want
to do something like `function(n, key){return n.length}`. The default is
`function(){return 1}`, which is fine if you want to store `max`
like-sized things. The item is passed as the first argument, and
the key is passed as the second argumnet.
* `dispose` Function that is called on items when they are dropped
from the cache. This can be handy if you want to close file
descriptors or do other cleanup tasks when items are no longer
accessible. Called with `key, value`. It's called *before*
actually removing the item from the internal cache, so if you want
to immediately put it back in, you'll have to do that in a
`nextTick` or `setTimeout` callback or it won't do anything.
* `stale` By default, if you set a `maxAge`, it'll only actually pull
stale items out of the cache when you `get(key)`. (That is, it's
not pre-emptively doing a `setTimeout` or anything.) If you set
`stale:true`, it'll return the stale value before deleting it. If
you don't set this, then it'll return `undefined` when you try to
get a stale entry, as if it had already been deleted.
* `noDisposeOnSet` By default, if you set a `dispose()` method, then
it'll be called whenever a `set()` operation overwrites an existing
key. If you set this option, `dispose()` will only be called when a
key falls out of the cache, not when it is overwritten.
* `updateAgeOnGet` When using time-expiring entries with `maxAge`,
setting this to `true` will make each item's effective time update
to the current time whenever it is retrieved from cache, causing it
to not expire. (It can still fall out of cache based on recency of
use, of course.)
## API
* `set(key, value, maxAge)`
* `get(key) => value`
Both of these will update the "recently used"-ness of the key.
They do what you think. `maxAge` is optional and overrides the
cache `maxAge` option if provided.
If the key is not found, `get()` will return `undefined`.
The key and val can be any value.
* `peek(key)`
Returns the key value (or `undefined` if not found) without
updating the "recently used"-ness of the key.
(If you find yourself using this a lot, you *might* be using the
wrong sort of data structure, but there are some use cases where
it's handy.)
* `del(key)`
Deletes a key out of the cache.
* `reset()`
Clear the cache entirely, throwing away all values.
* `has(key)`
Check if a key is in the cache, without updating the recent-ness
or deleting it for being stale.
* `forEach(function(value,key,cache), [thisp])`
Just like `Array.prototype.forEach`. Iterates over all the keys
in the cache, in order of recent-ness. (Ie, more recently used
items are iterated over first.)
* `rforEach(function(value,key,cache), [thisp])`
The same as `cache.forEach(...)` but items are iterated over in
reverse order. (ie, less recently used items are iterated over
first.)
* `keys()`
Return an array of the keys in the cache.
* `values()`
Return an array of the values in the cache.
* `length`
Return total length of objects in cache taking into account
`length` options function.
* `itemCount`
Return total quantity of objects currently in cache. Note, that
`stale` (see options) items are returned as part of this item
count.
* `dump()`
Return an array of the cache entries ready for serialization and usage
with 'destinationCache.load(arr)`.
* `load(cacheEntriesArray)`
Loads another cache entries array, obtained with `sourceCache.dump()`,
into the cache. The destination cache is reset before loading new entries
* `prune()`
Manually iterates over the entire cache proactively pruning old entries

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'
```
You can also just load the module for the function that you care about, if
you'd like to minimize your footprint.

```
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
-n <0|1>
This is the base to be used for the prerelease identifier.
-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`. The comparator `>1` is equivalent to `>=2.0.0` and
would match the versions `2.0.0` and `3.1.0`, but not the versions
`1.0.1` 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
```
#### Prerelease Identifier Base
The method `.inc` takes an optional parameter 'identifierBase' string
that will let you let your prerelease number as zero-based or one-based.
Set to `false` to omit the prerelease number altogether.
If you do not specify this parameter, it will default to zero-based.
```javascript
semver.inc('1.2.3', 'prerelease', 'beta', '1')
// '1.2.4-beta.1'
```
```javascript
semver.inc('1.2.3', 'prerelease', 'beta', false)
// '1.2.4-beta'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta -n 1
1.2.4-beta.1
```
```bash
$ semver 1.2.3 -i prerelease --preid beta -n false
1.2.4-beta
```
### 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 <2.4.0-0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
#### 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 non-prerelease version satisfies, unless
`includePrerelease` is specified, in which case any version at all
satisfies)
* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0-0` (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 <2.0.0-0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
#### 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 <1.3.0-0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` 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.
#### 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`
* `^0.2.3` := `>=0.2.3 <0.3.0-0`
* `^0.0.3` := `>=0.0.3 <0.0.4-0`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` 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 <0.0.4-0` 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`
* `^0.0.x` := `>=0.0.0 <0.1.0-0`
* `^0.0` := `>=0.0.0 <0.1.0-0`
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`
* `^0.x` := `>=0.0.0 <1.0.0-0`
### 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
* `simplifyRange(versions, range)`: Return a "simplified" range that
matches the same items in `versions` list as the range specified. Note
that it does *not* guarantee that it would match the same versions in all
cases, only for the set of versions provided. This is useful when
generating ranges by joining together multiple versions with `||`
programmatically, to provide the user with something a bit more
ergonomic. If the provided range is shorter in string-length than the
generated range, then that is returned.
* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
entirely contained by the `superRange` range.
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 `Number.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`
## Constants
As a convenience, helper constants are exported to provide information about what `node-semver` supports:
### `RELEASE_TYPES`
- major
- premajor
- minor
- preminor
- patch
- prepatch
- prerelease
```
const semver = require('semver');
if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
console.log('This is a valid release type!');
} else {
console.warn('This is NOT a valid release type!');
}
```
### `SEMVER_SPEC_VERSION`
2.0.0
```
const semver = require('semver');
console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
```
## Exported Modules
<!--
TODO: Make sure that all of these items are documented (classes aren't,
eg), and then pull the module name into the documentation for that specific
thing.
-->
You may pull in just the part of this semver utility that you need, if you
are sensitive to packing and tree-shaking concerns. The main
`require('semver')` export uses getter functions to lazily load the parts
of the API that are used.
The following modules are available:
* `require('semver')`
* `require('semver/classes')`
* `require('semver/classes/comparator')`
* `require('semver/classes/range')`
* `require('semver/classes/semver')`
* `require('semver/functions/clean')`
* `require('semver/functions/cmp')`
* `require('semver/functions/coerce')`
* `require('semver/functions/compare')`
* `require('semver/functions/compare-build')`
* `require('semver/functions/compare-loose')`
* `require('semver/functions/diff')`
* `require('semver/functions/eq')`
* `require('semver/functions/gt')`
* `require('semver/functions/gte')`
* `require('semver/functions/inc')`
* `require('semver/functions/lt')`
* `require('semver/functions/lte')`
* `require('semver/functions/major')`
* `require('semver/functions/minor')`
* `require('semver/functions/neq')`
* `require('semver/functions/parse')`
* `require('semver/functions/patch')`
* `require('semver/functions/prerelease')`
* `require('semver/functions/rcompare')`
* `require('semver/functions/rsort')`
* `require('semver/functions/satisfies')`
* `require('semver/functions/sort')`
* `require('semver/functions/valid')`
* `require('semver/ranges/gtr')`
* `require('semver/ranges/intersects')`
* `require('semver/ranges/ltr')`
* `require('semver/ranges/max-satisfying')`
* `require('semver/ranges/min-satisfying')`

`SemVer ${version}
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)
-n <base>
Base number to be used for the prerelease identifier.
Can be either 0 or 1, or false to omit the number altogether.
Defaults to 0.
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.`)
