## Goal and Philosophy
**`Inquirer.js`** strives to be an easily embeddable and beautiful command line interface for [Node.js](https://nodejs.org/) (and perhaps the "CLI [Xanadu](https://en.wikipedia.org/wiki/Citizen_Kane)").
**`Inquirer.js`** should ease the process of
- providing _error feedback_
- _asking questions_
- _parsing_ input
- _validating_ answers
- managing _hierarchical prompts_
> **Note:** **`Inquirer.js`** provides the user interface and the inquiry session flow. If you're searching for a full blown command line program utility, then check out [commander](https://github.com/visionmedia/commander.js), [vorpal](https://github.com/dthree/vorpal) or [args](https://github.com/leo/args).
## [Documentation](#documentation)
<a name="documentation"></a>
### Installation
<a name="installation"></a>
```shell
npm install inquirer
```
```javascript
var inquirer = require('inquirer');
inquirer
.prompt([
/* Pass your questions in here */
])
.then((answers) => {
// Use user feedback for... whatever!!
})
.catch((error) => {
if (error.isTtyError) {
// Prompt couldn't be rendered in the current environment
} else {
// Something else went wrong
}
});
```
<a name="examples"></a>
### Examples (Run it and see it)
Check out the [`packages/inquirer/examples/`](https://github.com/SBoudrias/Inquirer.js/tree/master/packages/inquirer/examples) folder for code and interface examples.
```shell
node packages/inquirer/examples/pizza.js
node packages/inquirer/examples/checkbox.js
# etc...
```
### Methods
<a name="methods"></a>
#### `inquirer.prompt(questions, answers) -> promise`
Launch the prompt interface (inquiry session)
- **questions** (Array) containing [Question Object](#question) (using the [reactive interface](#reactive-interface), you can also pass a `Rx.Observable` instance)
- **answers** (object) contains values of already answered questions. Inquirer will avoid asking answers already provided here. Defaults `{}`.
- returns a **Promise**
#### `inquirer.registerPrompt(name, prompt)`
Register prompt plugins under `name`.
- **name** (string) name of the this new prompt. (used for question `type`)
- **prompt** (object) the prompt object itself (the plugin)
#### `inquirer.createPromptModule() -> prompt function`
Create a self contained inquirer module. If you don't want to affect other libraries that also rely on inquirer when you overwrite or add new prompt types.
```js
var prompt = inquirer.createPromptModule();
prompt(questions).then(/* ... */);
```
### Objects
<a name="objects"></a>
#### Question
<a name="questions"></a>
A question object is a `hash` containing question related values:
- **type**: (String) Type of the prompt. Defaults: `input` - Possible values: `input`, `number`, `confirm`,
`list`, `rawlist`, `expand`, `checkbox`, `password`, `editor`
- **name**: (String) The name to use when storing the answer in the answers hash. If the name contains periods, it will define a path in the answers hash.
- **message**: (String|Function) The question to print. If defined as a function, the first parameter will be the current inquirer session answers. Defaults to the value of `name` (followed by a colon).
- **default**: (String|Number|Boolean|Array|Function) Default value(s) to use if nothing is entered, or a function that returns the default value(s). If defined as a function, the first parameter will be the current inquirer session answers.
- **choices**: (Array|Function) Choices array or a function returning a choices array. If defined as a function, the first parameter will be the current inquirer session answers.
Array values can be simple `numbers`, `strings`, or `objects` containing a `name` (to display in list), a `value` (to save in the answers hash), and a `short` (to display after selection) properties. The choices array can also contain [a `Separator`](#separator).
- **validate**: (Function) Receive the user input and answers hash. Should return `true` if the value is valid, and an error message (`String`) otherwise. If `false` is returned, a default error message is provided.
- **filter**: (Function) Receive the user input and answers hash. Returns the filtered value to be used inside the program. The value returned will be added to the _Answers_ hash.
- **transformer**: (Function) Receive the user input, answers hash and option flags, and return a transformed value to display to the user. The transformation only impacts what is shown while editing. It does not modify the answers hash.
- **when**: (Function, Boolean) Receive the current user answers hash and should return `true` or `false` depending on whether or not this question should be asked. The value can also be a simple boolean.
- **pageSize**: (Number) Change the number of lines that will be rendered when using `list`, `rawList`, `expand` or `checkbox`.
- **prefix**: (String) Change the default _prefix_ message.
- **suffix**: (String) Change the default _suffix_ message.
- **askAnswered**: (Boolean) Force to prompt the question if the answer already exists.
- **loop**: (Boolean) Enable list looping. Defaults: `true`
`default`, `choices`(if defined as functions), `validate`, `filter` and `when` functions can be called asynchronously. Either return a promise or use `this.async()` to get a callback you'll call with the final value.
```javascript
{
/* Preferred way: with promise */
filter() {
return new Promise(/* etc... */);
},
/* Legacy way: with this.async */
validate: function (input) {
// Declare function as asynchronous, and save the done callback
var done = this.async();
// Do async stuff
setTimeout(function() {
if (typeof input !== 'number') {
// Pass the return value in the done callback
done('You need to provide a number');
return;
}
// Pass the return value in the done callback
done(null, true);
}, 3000);
}
}
```
### Answers
<a name="answers"></a>
A key/value hash containing the client answers in each prompt.
- **Key** The `name` property of the _question_ object
- **Value** (Depends on the prompt)
- `confirm`: (Boolean)
- `input` : User input (filtered if `filter` is defined) (String)
- `number`: User input (filtered if `filter` is defined) (Number)
- `rawlist`, `list` : Selected choice value (or name if no value specified) (String)
### Separator
<a name="separator"></a>
A separator can be added to any `choices` array:
```
// In the question object
choices: [ "Choice A", new inquirer.Separator(), "choice B" ]
// Which'll be displayed this way
[?] What do you want to do?
> Order a pizza
Make a reservation
--------
Ask opening hours
Talk to the receptionist
```
The constructor takes a facultative `String` value that'll be use as the separator. If omitted, the separator will be `--------`.
Separator instances have a property `type` equal to `separator`. This should allow tools façading Inquirer interface from detecting separator types in lists.
<a name="prompt"></a>
### Prompt types
---
> **Note:**: _allowed options written inside square brackets (`[]`) are optional. Others are required._
#### List - `{type: 'list'}`
Take `type`, `name`, `message`, `choices`[, `default`, `filter`, `loop`] properties.
(Note: `default` must be set to the `index` or `value` of one of the entries in `choices`)
![List prompt](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/list.svg)
---
#### Raw List - `{type: 'rawlist'}`
Take `type`, `name`, `message`, `choices`[, `default`, `filter`, `loop`] properties.
(Note: `default` must be set to the `index` of one of the entries in `choices`)
![Raw list prompt](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/rawlist.svg)
---
#### Expand - `{type: 'expand'}`
Take `type`, `name`, `message`, `choices`[, `default`] properties.
Note: `default` must be the `index` of the desired default selection of the array. If `default` key not provided, then `help` will be used as default choice
Note that the `choices` object will take an extra parameter called `key` for the `expand` prompt. This parameter must be a single (lowercased) character. The `h` option is added by the prompt and shouldn't be defined by the user.
See `examples/expand.js` for a running example.
![Expand prompt closed](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/expand-y.svg)
![Expand prompt expanded](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/expand-d.svg)
---
#### Checkbox - `{type: 'checkbox'}`
Take `type`, `name`, `message`, `choices`[, `filter`, `validate`, `default`, `loop`] properties. `default` is expected to be an Array of the checked choices value.
Choices marked as `{checked: true}` will be checked by default.
Choices whose property `disabled` is truthy will be unselectable. If `disabled` is a string, then the string will be outputted next to the disabled choice, otherwise it'll default to `"Disabled"`. The `disabled` property can also be a synchronous function receiving the current answers as argument and returning a boolean or a string.
![Checkbox prompt](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/checkbox.svg)
---
#### Confirm - `{type: 'confirm'}`
Take `type`, `name`, `message`, [`default`] properties. `default` is expected to be a boolean if used.
![Confirm prompt](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/confirm.svg)
---
#### Input - `{type: 'input'}`
Take `type`, `name`, `message`[, `default`, `filter`, `validate`, `transformer`] properties.
![Input prompt](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/input.svg)
---
#### Input - `{type: 'number'}`
Take `type`, `name`, `message`[, `default`, `filter`, `validate`, `transformer`] properties.
---
#### Password - `{type: 'password'}`
Take `type`, `name`, `message`, `mask`,[, `default`, `filter`, `validate`] properties.
![Password prompt](https://cdn.rawgit.com/SBoudrias/Inquirer.js/28ae8337ba51d93e359ef4f7ee24e79b69898962/assets/screenshots/password.svg)
---
Note that `mask` is required to hide the actual user input.
#### Editor - `{type: 'editor'}`
Take `type`, `name`, `message`[, `default`, `filter`, `validate`, `postfix`] properties
Launches an instance of the users preferred editor on a temporary file. Once the user exits their editor, the contents of the temporary file are read in as the result. The editor to use is determined by reading the $VISUAL or $EDITOR environment variables. If neither of those are present, notepad (on Windows) or vim (Linux or Mac) is used.
The `postfix` property is useful if you want to provide an extension.
<a name="layouts"></a>
### Use in Non-Interactive Environments
`prompt()` requires that it is run in an interactive environment. (I.e. [One where `process.stdin.isTTY` is `true`](https://nodejs.org/docs/latest-v12.x/api/process.html#process_a_note_on_process_i_o)). If `prompt()` is invoked outside of such an environment, then `prompt()` will return a rejected promise with an error. For convenience, the error will have a `isTtyError` property to programmatically indicate the cause.
## User Interfaces and layouts
Along with the prompts, Inquirer offers some basic text UI.
#### Bottom Bar - `inquirer.ui.BottomBar`
This UI present a fixed text at the bottom of a free text zone. This is useful to keep a message to the bottom of the screen while outputting command outputs on the higher section.
```javascript
var ui = new inquirer.ui.BottomBar();
// pipe a Stream to the log zone
outputStream.pipe(ui.log);
// Or simply write output
ui.log.write('something just happened.');
ui.log.write('Almost over, standby!');
// During processing, update the bottom bar content to display a loader
// or output a progress bar, etc
ui.updateBottomBar('new bottom bar content');
```
<a name="reactive"></a>
## Reactive interface
Internally, Inquirer uses the [JS reactive extension](https://github.com/ReactiveX/rxjs) to handle events and async flows.
This mean you can take advantage of this feature to provide more advanced flows. For example, you can dynamically add questions to be asked:
```js
var prompts = new Rx.Subject();
inquirer.prompt(prompts);
// At some point in the future, push new questions
prompts.next({
/* question... */
});
prompts.next({
/* question... */
});
// When you're done
prompts.complete();
```
And using the return value `process` property, you can access more fine grained callbacks:
```js
inquirer.prompt(prompts).ui.process.subscribe(onEachAnswer, onError, onComplete);
```
## Support (OS Terminals)
<a name="support"></a>
You should expect mostly good support for the CLI below. This does not mean we won't
look at issues found on other command line - feel free to report any!
- **Mac OS**:
- Terminal.app
- iTerm
- **Windows ([Known issues](#issues))**:
- [ConEmu](https://conemu.github.io/)
- cmd.exe
- Powershell
- Cygwin
- **Linux (Ubuntu, openSUSE, Arch Linux, etc)**:
- gnome-terminal (Terminal GNOME)
- konsole
## Known issues
<a name="issues"></a>
Running Inquirer together with network streams in Windows platform inside some terminals can result in process hang.
Workaround: run inside another terminal.
Please refer to the https://github.com/nodejs/node/issues/21771
Calling a node script that uses Inquirer from grunt-exec can cause the program to crash. To fix this, add to your grunt-exec config `stdio: 'inherit'`.
Please refer to https://github.com/jharding/grunt-exec/issues/85
## News on the march (Release notes)
<a name="news"></a>
Please refer to the [GitHub releases section for the changelog](https://github.com/SBoudrias/Inquirer.js/releases)
## Contributing
<a name="contributing"></a>
**Unit test**
Unit test are written in [Mocha](https://mochajs.org/). Please add a unit test for every new feature or bug fix. `npm test` to run the test suite.
**Documentation**
Add documentation for every API change. Feel free to send typo fixes and better docs!
We're looking to offer good support for multiple prompts and environments. If you want to
help, we'd like to keep a list of testers for each terminal/OS so we can contact you and
get feedback before release. Let us know if you want to be added to the list (just tweet

# 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);
```

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!')`

## 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

# 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.
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.
