Package for formatting JSON data in a coloured YAML-style, perfect for CLI output.

## How to install

Just install it via NPM:

```bash

$ npm install -g prettyjson

```

This will install `prettyjson` globally, so it will be added automatically

to your `PATH`.

## Using it (from the CLI)

This package installs a command line interface to render JSON data in a more

convenient way. You can use the CLI in three different ways:

**Decode a JSON file:** If you want to see the contents of a JSON file, just pass

it as the first argument to the CLI:

```bash

$ prettyjson package.json

```

![Example 1](https://raw.github.com/rafeca/prettyjson/master/images/example3.png)

**Decode the stdin:** You can also pipe the result of a command (for example an

HTTP request) to the CLI to see the JSON result in a clearer way:

```bash

$ curl https://api.github.com/users/rafeca | prettyjson

```

![Example 2](https://raw.github.com/rafeca/prettyjson/master/images/example4.png)

**Decode random strings:** if you call the CLI with no arguments, you'll get a

prompt where you can past JSON strings and they'll be automatically displayed in a clearer way:

![Example 3](https://raw.github.com/rafeca/prettyjson/master/images/example5.png)

### Command line options

It's possible to customize the output through some command line options:

```bash

# Change colors

$ prettyjson --string=red --multiline_string=cyan --keys=blue --dash=yellow --number=green package.json

# Do not use colors

$ prettyjson --nocolor=1 package.json

# Change indentation

$ prettyjson --indent=4 package.json

# Render arrays elements in a single line

$ prettyjson --inline-arrays=1 package.json

# Escape conflictive strings

$ prettyjson --escape=1 package.json

```

**Deprecation Notice**: The old configuration through environment variables is

deprecated and it will be removed in the next major version (1.0.0).

## Using it (from Node.js)

It's pretty easy to use it. You just have to include it in your script and call

the `render()` method:

```javascript

var prettyjson = require('prettyjson');

var data = {

  username: 'rafeca',

  url: 'https://github.com/rafeca',

  twitter_account: 'https://twitter.com/rafeca',

  projects: ['prettyprint', 'connfu']

};

var options = {

  noColor: true

};

console.log(prettyjson.render(data, options));

```

And will output:

![Example 4](https://raw.github.com/rafeca/prettyjson/master/images/example1.png)

You can also configure the colors of the hash keys and array dashes

(using [colors.js](https://github.com/Marak/colors.js) colors syntax):

```javascript

var prettyjson = require('prettyjson');

var data = {

  username: 'rafeca',

  url: 'https://github.com/rafeca',

  twitter_account: 'https://twitter.com/rafeca',

  projects: ['prettyprint', 'connfu']

};

console.log(prettyjson.render(data, {

  keysColor: 'rainbow',

  dashColor: 'magenta',

  stringColor: 'white',

  multilineStringColor: 'cyan'

}));

```

Will output something like:

## Running Tests

To run the test suite first invoke the following command within the repo,

installing the development dependencies:

```bash

$ npm install

```

then run the tests:

```bash

$ npm test

```

On windows, you can run the tests with:

```cmd

C:\git\prettyjson> npm run-script testwin

```
