wide-align
|
||
|
|
----------
|
||
|
|
|
||
|
|
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.
