								----------
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								A wide-character aware text alignment function for use in terminals / on the
							 | 
						||
| 
								 | 
							
								console.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								### Usage
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								```
							 | 
						||
| 
								 | 
							
								var align = require('wide-align')
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								// Note that if you view this on a unicode console, all of the slashes are
							 | 
						||
| 
								 | 
							
								// aligned. This is because on a console, all narrow characters are
							 | 
						||
| 
								 | 
							
								// an en wide and all wide characters are an em. In browsers, this isn't
							 | 
						||
| 
								 | 
							
								// held to and wide characters like "古" can be less than two narrow
							 | 
						||
| 
								 | 
							
								// characters even with a fixed width font.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								console.log(align.center('abc', 10))     // '   abc    '
							 | 
						||
| 
								 | 
							
								console.log(align.center('古古古', 10))  // '  古古古  '
							 | 
						||
| 
								 | 
							
								console.log(align.left('abc', 10))       // 'abc       '
							 | 
						||
| 
								 | 
							
								console.log(align.left('古古古', 10))    // '古古古    '
							 | 
						||
| 
								 | 
							
								console.log(align.right('abc', 10))      // '       abc'
							 | 
						||
| 
								 | 
							
								console.log(align.right('古古古', 10))   // '    古古古'
							 | 
						||
| 
								 | 
							
								```

								### Origins
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								These functions were originally taken from 
							 | 
						||
| 
								 | 
							
								[cliui](https://npmjs.com/package/cliui). Changes include switching to the
							 | 
						||
| 
								 | 
							
								MUCH faster pad generation function from
							 | 
						||
| 
								 | 
							
								[lodash](https://npmjs.com/package/lodash), making center alignment pad
							 | 
						||
| 
								 | 
							
								both sides and adding left alignment.
