===========
|
|
A cored, fixed, documented and optimized version of the popular [colors.js](https://github.com/Marak/colors.js). Can be
|
|
used as a drop-in replacement, also works correctly in the browser, provides a CSS mode and has been compiled through
|
|
Closure Compiler using advanced optimizations. Additionally, nearly every issue and pull request on the original has
|
|
been incorporated.
|
|
|
|
Installation
|
|
------------
|
|
`npm install colour`
|
|
|
|
Usage
|
|
-----
|
|
This package extends the global String prototype with additional getters that apply terminal colors to your texts.
|
|
Available styles are:
|
|
|
|
* **Emphasis:** bold, italic, underline, inverse
|
|
* **Colors:** yellow, cyan, white, magenta, green, red, grey, blue
|
|
* **Sequencers:** rainbow, zebra, random
|
|
|
|
#### Example
|
|
|
|
```js
|
|
var colour = require('colour');
|
|
console.log('hello'.green); // outputs green text
|
|
console.log('i like cake and pies'.underline.red) // outputs red underlined text
|
|
console.log('inverse the color'.inverse); // inverses the color
|
|
console.log('OMG Rainbows!'.rainbow); // rainbow (ignores spaces)
|
|
```
|
|
|
|
#### Or: As a drop-in replacement for `colors`
|
|
```js
|
|
var /* just name it */ colors = require('colour');
|
|
...
|
|
```
|
|
|
|
Custom themes
|
|
-------------
|
|
Its also possible to define your own themes by creating new getters on the String object. Example:
|
|
|
|
```js
|
|
var colour = require('colour');
|
|
colour.setTheme({
|
|
silly: 'rainbow',
|
|
input: 'grey',
|
|
verbose: 'cyan',
|
|
prompt: 'grey',
|
|
info: 'green',
|
|
data: 'grey',
|
|
help: 'cyan',
|
|
warn: ['yellow', 'underline'], // Applies two styles at once
|
|
debug: 'blue',
|
|
error: 'red bold' // Again, two styles
|
|
});
|
|
|
|
console.log("this is an error".error); // outputs bold red text
|
|
console.log("this is a warning".warn); // outputs underlined yellow text
|
|
|
|
console.log(colour.green("this is green")); // Alternatively
|
|
```
|
|
|
|
Console, browser and browser-css mode
|
|
-------------------------------------
|
|
```js
|
|
var colour = require('colour');
|
|
...
|
|
colour.mode = 'none'; // No colors at all
|
|
colour.mode = 'console'; // Adds terminal colors (default on node.js)
|
|
colour.mode = 'browser'; // Adds HTML colors (default in browsers)
|
|
colour.mode = 'browser-css'; // Adds special CSS (see examples/example.css)
|
|
```
|
|
|
|
Uninstalling / reinstalling on the global scope
|
|
-----------------------------------------------
|
|
If you have a reason to use a fresh String prototype in your application, you may also revert all extensions made.
|
|
|
|
```js
|
|
var colour = require('colour');
|
|
...
|
|
colour.uninstall(); // Removes all custom properties from the String prototype
|
|
...
|
|
colour.install(); // Re-installs them
|
|
...
|
|
```
|
|
|
|
