Fast Color JSON Marshaller + Pretty Printer for Golang

ColorJSON: The Fast Color JSON Marshaller for Go

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.

Installation

go get -u github.com/TylerBrock/colorjson

Usage

Setup

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

s, _ := colorjson.Marshal(obj)
fmt.Println(string(s))

Customization (Custom Indent)

f := colorjson.NewFormatter()
f.Indent = 2

s, _ := f.Marshal(v)
fmt.Println(string(s))
