prettyjson   

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

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

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:

$3

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

`bash


Change colors

$ prettyjson --string=red --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
`

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

You can also configure the colors of the hash keys and array dashes
(using 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'
}));
`

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
