# Node.js pad

[![Build Status](https://secure.travis-ci.org/adaltas/node-pad.png)](http://travis-ci.org/adaltas/node-pad)

Node Pad is a simple and elegant function to pad strings in both left and right directions.

## Usage

The API is quite simple:

```javascript
const pad = require('pad')
pad('pad', 5)      // "pad  "
pad(5, 'pad')      // "  pad"
pad('pad', 5, '+') // "pad++"
pad(5, 'pad', '+') // "++pad"
```

For TypeScript users, the type definition files are located in "./lib/index.d.ts" and declared inside the "package.json" file.

## Bundles

Node Pad comes in multiple flavours depending on your target environment:

* CommonJS: `dist/pad.cjs.js`   
  Bundle used by Node.js and compatible with ES5. It is declared inside the `package.json` by the `main` property and used by default with `require("pad")` in a Node.js environment.
* ES module: `dist/pad.esm.js`   
  Bundle using the ECMAScript standard defined in ES6 for working with modules. The path to the ES module is declared inside the `package.json` by the `module` property for ESM-aware tools like [Rollup](https://rollupjs.org) and [webpack 2+](https://webpack.js.org/).
* UMD: `dis/pad.umd.js`
  Bundle in the Universal Module Definition (UMD), a format compatible with both AMD and CommonJS.

The CommonJS syntax to import Node Pad is:

```js
const pad = require("pad/dist/pad.cjs.js")
// Or simply
const pad = require("pad")
```

While the ES Modules syntax is:

```js
import pad from "pad/dist/pad.esm.js"
// Or for ESM-aware tools
import pad from "pad"
```

## Options

Options are provided as a third argument and are all optional. A string argument
it is interpreted as the "char" option. Accepted options include:

* `char` (string)   
  The character used to fill the gap.
* `colors` (boolean)   
  Ajust to hidden terminal color characters, you may also use `require 'pad/lib/colors'` to avoid passing this option.
* `strip` (boolean)   
  Remove characters from text if length smaller than text length, default to "false".
* `fixed_width` (boolean)   
  An optimization option to disable the usage of the wcwdith package to handle the discovery of characters using more than one column for display.
  one column to display
* `wcwidth_options` (object)   
  Options passed to the wcwidth package used to calculate the display width of
  characters using more than one column.

## Left padding: `pad(length, text, [options])`

Left padding occurs when the first argument is a number and the second
argument is a string.

```javascript
var pad = require('pad');
pad(5, 'pad', '-').should.eql('--pad');
```

## Right padding: `pad(text, length, [options])`

Right padding occurs when the first argument is a string and the second
argument is a number.

```javascript
var pad = require('pad');
pad('pad', 6).should.eql('pad   ');
```

## Installing

Starting with version 1.1.0, Node pad rely on Node.js 4.0.0 or more recent.
Stick to version 1.0.x if using an older version of Node.js.

Via [npm](http://github.com/isaacs/npm):

```bash
npm install pad
```

Via git (or downloaded tarball), copy or link the project from a discoverable
Node.js directory:

```bash
git clone http://github.com/wdavidw/node-pad.git
```

## Testing

Clone the repo, install the development dependencies and run the suite:

```bash
git clone http://github.com/wdavidw/node-pad.git .
npm install
make test
```
