ColorJSON: The Fast Color JSON Marshaller for Go

================================================

![ColorJSON Output](https://i.imgur.com/pLtCXhb.png)

What is this?

-------------

This package is based heavily on hokaccha/go-prettyjson but has some noticible differences:

 - Over twice as fast (recursive descent serialization uses buffer instead of string concatenation)

   ```

   BenchmarkColorJSONMarshall-4     500000      2498 ns/op

   BenchmarkPrettyJSON-4            200000      6145 ns/op

   ```

 - more customizable (ability to have zero indent, print raw json strings, etc...)

 - better defaults (less bold colors)

ColorJSON was built in order to produce fast beautiful colorized JSON output for [Saw](http://github.com/TylerBrock/saw).

Installation

------------

```sh

go get -u github.com/TylerBrock/colorjson

```

Usage

-----

Setup

```go

import "github.com/TylerBrock/colorjson"

str := `{

  "str": "foo",

  "num": 100,

  "bool": false,

  "null": null,

  "array": ["foo", "bar", "baz"],

  "obj": { "a": 1, "b": 2 }

}`

// Create an intersting JSON object to marshal in a pretty format

var obj map[string]interface{}

json.Unmarshal([]byte(str), &obj)

```

Vanilla Usage

```go

s, _ := colorjson.Marshal(obj)

fmt.Println(string(s))

```

Customization (Custom Indent)

```go

f := colorjson.NewFormatter()

f.Indent = 2

s, _ := f.Marshal(v)

fmt.Println(string(s))

```
