## Usage
|
||
|
|
||
|
By popular demand, `colors` now ships with two types of usages!
|
||
|
|
||
|
The super nifty way
|
||
|
|
||
|
```js
|
||
|
var colors = require('colors');
|
||
|
|
||
|
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
|
||
|
console.log('Run the trap'.trap); // Drops the bass
|
||
|
|
||
|
```
|
||
|
|
||
|
or a slightly less nifty way which doesn't extend `String.prototype`
|
||
|
|
||
|
```js
|
||
|
var colors = require('colors/safe');
|
||
|
|
||
|
console.log(colors.green('hello')); // outputs green text
|
||
|
console.log(colors.red.underline('i like cake and pies')) // outputs red underlined text
|
||
|
console.log(colors.inverse('inverse the color')); // inverses the color
|
||
|
console.log(colors.rainbow('OMG Rainbows!')); // rainbow
|
||
|
console.log(colors.trap('Run the trap')); // Drops the bass
|
||
|
|
||
|
```
|
||
|
|
||
|
I prefer the first way. Some people seem to be afraid of extending `String.prototype` and prefer the second way.
|
||
|
|
||
|
If you are writing good code you will never have an issue with the first approach. If you really don't want to touch `String.prototype`, the second usage will not touch `String` native object.
|
||
|
|
||
|
## Enabling/Disabling Colors
|
||
|
|
||
|
The package will auto-detect whether your terminal can use colors and enable/disable accordingly. When colors are disabled, the color functions do nothing. You can override this with a command-line flag:
|
||
|
|
||
|
```bash
|
||
|
node myapp.js --no-color
|
||
|
node myapp.js --color=false
|
||
|
|
||
|
node myapp.js --color
|
||
|
node myapp.js --color=true
|
||
|
node myapp.js --color=always
|
||
|
|
||
|
FORCE_COLOR=1 node myapp.js
|
||
|
```
|
||
|
|
||
|
Or in code:
|
||
|
|
||
|
```javascript
|
||
|
var colors = require('colors');
|
||
|
colors.enable();
|
||
|
colors.disable();
|
||
|
```
|
||
|
|
||
|
## Console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data)
|
||
|
|
||
|
```js
|
||
|
var name = 'Marak';
|
||
|
console.log(colors.green('Hello %s'), name);
|
||
|
// outputs -> 'Hello Marak'
|
||
|
```
|
||
|
|
||
|
## Custom themes
|
||
|
|
||
|
### Using standard API
|
||
|
|
||
|
```js
|
||
|
|
||
|
var colors = require('colors');
|
||
|
|
||
|
colors.setTheme({
|
||
|
silly: 'rainbow',
|
||
|
input: 'grey',
|
||
|
verbose: 'cyan',
|
||
|
prompt: 'grey',
|
||
|
info: 'green',
|
||
|
data: 'grey',
|
||
|
help: 'cyan',
|
||
|
warn: 'yellow',
|
||
|
debug: 'blue',
|
||
|
error: 'red'
|
||
|
});
|
||
|
|
||
|
// outputs red text
|
||
|
console.log("this is an error".error);
|
||
|
|
||
|
// outputs yellow text
|
||
|
console.log("this is a warning".warn);
|
||
|
```
|
||
|
|
||
|
### Using string safe API
|
||
|
|
||
|
```js
|
||
|
var colors = require('colors/safe');
|
||
|
|
||
|
// set single property
|
||
|
var error = colors.red;
|
||
|
error('this is red');
|
||
|
|
||
|
// set theme
|
||
|
colors.setTheme({
|
||
|
silly: 'rainbow',
|
||
|
input: 'grey',
|
||
|
verbose: 'cyan',
|
||
|
prompt: 'grey',
|
||
|
info: 'green',
|
||
|
data: 'grey',
|
||
|
help: 'cyan',
|
||
|
warn: 'yellow',
|
||
|
debug: 'blue',
|
||
|
error: 'red'
|
||
|
});
|
||
|
|
||
|
// outputs red text
|
||
|
console.log(colors.error("this is an error"));
|
||
|
|
||
|
// outputs yellow text
|
||
|
console.log(colors.warn("this is a warning"));
|
||
|
|
||
|
```
|
||
|
|
||
|
### Combining Colors
|
||
|
|
||
|
```javascript
|
||
|
var colors = require('colors');
|
||
|
|
||
|
colors.setTheme({
|
||
|
custom: ['red', 'underline']
|
||
|
});
|
||
|
|
||
|
console.log('test'.custom);
|
||
|
```
|
||
|
|
||
|
*Protip: There is a secret undocumented style in `colors`. If you find the style you can summon him.*
