As of `v3.0` the Chalk-style syntax (magical getter) is no longer used.<br>If you need or require that syntax, consider using [`ansi-colors`](https://github.com/doowb/ansi-colors), which maintains `chalk` parity.

## Install
|
||
|
|
|
||
|
|
```
|
||
|
|
$ npm install --save kleur
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
const { red, white, blue, bold } = require('kleur');
|
||
|
|
|
||
|
|
// basic usage
|
||
|
|
red('red text');
|
||
|
|
|
||
|
|
// chained methods
|
||
|
|
blue().bold().underline('howdy partner');
|
||
|
|
|
||
|
|
// nested methods
|
||
|
|
bold(`${ white().bgRed('[ERROR]') } ${ red().italic('Something happened')}`);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Chained Methods
|
||
|
|
|
||
|
|
```js
|
||
|
|
console.log(bold().red('this is a bold red message'));
|
||
|
|
console.log(bold().italic('this is a bold italicized message'));
|
||
|
|
console.log(bold().yellow().bgRed().italic('this is a bold yellow italicized message'));
|
||
|
|
console.log(green().bold().underline('this is a bold green underlined message'));
|
||
|
|
```
|
||
|
|
|
||
|
|
<img src="shots/1.png" width="300" />
|
||
|
|
|
||
|
|
### Nested Methods
|
||
|
|
|
||
|
|
```js
|
||
|
|
const { yellow, red, cyan } = require('kleur');
|
||
|
|
|
||
|
|
console.log(yellow(`foo ${red().bold('red')} bar ${cyan('cyan')} baz`));
|
||
|
|
console.log(yellow('foo ' + red().bold('red') + ' bar ' + cyan('cyan') + ' baz'));
|
||
|
|
```
|
||
|
|
|
||
|
|
<img src="shots/2.png" width="300" />
|
||
|
|
|
||
|
|
|
||
|
|
### Conditional Support
|
||
|
|
|
||
|
|
Toggle color support as needed; `kleur` includes simple auto-detection which may not cover all cases.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const kleur = require('kleur');
|
||
|
|
|
||
|
|
// manually disable
|
||
|
|
kleur.enabled = false;
|
||
|
|
|
||
|
|
// or use another library to detect support
|
||
|
|
kleur.enabled = require('color-support').level;
|
||
|
|
|
||
|
|
console.log(kleur.red('I will only be colored red if the terminal supports colors'));
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
Any `kleur` method returns a `String` when invoked with input; otherwise chaining is expected.
|
||
|
|
|
||
|
|
> It's up to the developer to pass the output to destinations like `console.log`, `process.stdout.write`, etc.
|
||
|
|
|
||
|
|
The methods below are grouped by type for legibility purposes only. They each can be [chained](#chained-methods) or [nested](#nested-methods) with one another.

## Credits
|
||
|
|
|
||
|
|
This project originally forked [Brian Woodward](https://github.com/doowb)'s awesome [`ansi-colors`](https://github.com/doowb/ansi-colors) library.
|
||
|
|
|
||
|
|
Beginning with `kleur@3.0`, the Chalk-style syntax (magical getter) has been replaced with function calls per key:
|
||
|
|
|
||
|
|
```js
|
||
|
|
// Old:
|
||
|
|
c.red.bold.underline('old');
|
||
|
|
|
||
|
|
// New:
|
||
|
|
c.red().bold().underline('new');
|
||
|
|
```
|
||
|
|
> <sup><em>As I work more with Rust, the newer syntax feels so much better & more natural!</em></sup>
|
||
|
|
|
||
|
|
If you prefer the old syntax, you may migrate to `ansi-colors`. Versions below `kleur@3.0` have been deprecated.
