ColorJSON: The Fast Color JSON Marshaller for Go

What is this?

This package is based heavily on TylerBrock/colorjson but uses direct-to-stream serialisation to a io.Writer interface via an internal buffer.

Installation

go get -u github.com/relvacode/colorjson

Usage

Setup

import "github.com/relvacode/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

// Use stdout, or any other standard io.Writer interface
_, err := colorjson.Marshal(os.Stdout, obj)

Customization (Custom Indent)

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

_, err := f.Marshal(os.Stdout, obj)
