rainbow-word

A node module that uses chalk.js to write strings in a colored/stylized pattern.

package.json

{
  ...
  "dependencies": {
    ...
    "rainbow-word": "git://github.com/unenglishable/rainbow-word",
    ...
  },
  ...
}

Usage

var rw = require('rainbow-word');

Pattern

var rw = require('rainbow-word');
var rainbow = rw.pattern(options);
rainbow.convert('Hello', 'World', ...);

.convert(string1, string2, ...);

.convert() will combine all arguments supplied to it into a single string. Cycling through elements in the scheme array, it converts each argument accordingly.

For a complete list of colors and styles, see the chalk.js git repo.

// Use the default pattern
var default = rw.pattern();
/*
 *  color: '',
 *  scheme: [
 *    {color: 'red'},
 *    {color: 'yellow'},
 *    {color: 'green'},
 *    {color: 'blue'},
 *    {color: 'magenta'}],
 *  styles: [],
 *  save: false
 */

// Supply options to the pattern constructor
var options = {
  color: 'red',
  bgColor: 'bgWhite',
  style: 'bold,
  styles: ['bold', 'underline', ...],
  scheme: [
    {color: 'red', bgColor: 'bgWhite', style: 'bold', styles: ['bold', 'underline', ...]},
    {color: 'blue', style: 'bold'},
    {color: 'white', styles: ['bold', 'underline', ...]},
    {color: 'black'},
    ... ];
  save: true
}

Options are parsed as follows:

• Anything provided in the scheme has priority (overrides other options)

• style overrides styles

• If color is not provided in scheme, color option will be used.

• bgColor behaves the same way as color

• If style/styles is/are not provided in scheme, style/styles option will be used.

• If nothing is provided, defaults will be used

The save option specifies that the pattern should keep track of the last element in the scheme it used and continue there on the next call to .convert(). If save is false, the position is reset after each call to .convert().
