# justify-text
|
|
|
|
This is a simple module, which allows for left or right justifying text
|
|
in a given width. The padding character can be specified, and it defaults
|
|
to a space.
|
|
|
|
Numbers are explicily handled now, so they do not need to be converted to
|
|
a string before passing them to `ljust` or `rjust` any more.
|
|
|
|
If the padding width specified is less than the length of the initial string,
|
|
no truncation occurs.
|
|
|
|
## Installation
|
|
|
|
```
|
|
npm install -S justify-text
|
|
```
|
|
|
|
or
|
|
|
|
```
|
|
yarn add justify-text
|
|
```
|
|
|
|
## Functions
|
|
|
|
`ljust()` and `rjust()` take a string or number, a width to render it in,
|
|
and an optional padding character, which is a space by default.
|
|
|
|
``` js
|
|
ljust(string, width, padding=' ')
|
|
rjust(string, width, padding=' ')
|
|
```
|
|
|
|
### Usage
|
|
|
|
``` js
|
|
const { ljust, rjust } = require('justify-text');
|
|
|
|
ljust('text', 7);
|
|
// => "text "
|
|
|
|
ljust('text', 6, '0');
|
|
// => "text00"
|
|
|
|
rjust('text', 8);
|
|
// => " text"
|
|
|
|
rjust('longtext', 7);
|
|
// => "longtext", i.e. unchanged because it is already more than 7 characters
|
|
|
|
rjust('text', 9, '.');
|
|
// => ".....text"
|
|
|
|
rjust(936, 5);
|
|
// => " 936"
|
|
|
|
ljust(780.25, 8);
|
|
// => "780.25 "
|
|
```
