|

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

||||

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