json5b

Now based on titanous/json5 package instead of yosuke-furukawa/json5

This is a Go package that implements decoding of JSON5. See the documentation for usage information.

• The tag being used is json5 instead of json
• merged the patch from skybosi to support autoconvert string to number, added more tests

HOW TO USE

go install github.com/kokizzu/json5b 
$ json5 -c path/to/test.json5 # output stdout
$ json5 -c path/to/test.json5 -o path/to/test.json # output path/to/test.json

go get

$ go get github.com/kokizzu/json5b

example

package main

import (
	"encoding/json"
	"fmt"
	"os"

	"github.com/kokizzu/json5b/encoding/json5b"
)

func main() {
	var data interface{}
	dec := json5b.NewDecoder(os.Stdin)
	err := dec.Decode(&data)
	if err != nil {
		fmt.Println(err)
	}
	b, err := json.MarshalIndent(data, "", "    ")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(string(b))
}

// This is json5 demo
// json5 can write comment in your json
{
  key : "Key does not need double quote",
  // json specific
  "of" : "course we can use json as json5",
  trailing : "trailing comma is ok",
}

$ json5 -c example.json5
# output
#{
#    "key": "Key does not need double quote",
#    "of": "course we can use json as json5",
#    "trailing": "trailing comma is ok"
#}

Example using fiber

package main

import (
	"github.com/gofiber/fiber/v2"
	"github.com/kokizzu/json5b/encoding/json5b"
)

func main() {
	app := fiber.New(fiber.Config{
		Immutable: true, // if you are using
		JSONDecoder: json5b.Unmarshal,
	})

	app.Post("/json5", func(c *fiber.Ctx) error {
		var data struct {
			Name string //`json5:"name"` // will still work even when no tag
			Age  int    `json5:"age"`
		}
		err := c.BodyParser(&data)
		if err != nil {
			return c.Status(fiber.StatusBadRequest).JSON(fiber.Map{
				"error": err.Error(),
			})
	 	}
		return c.JSON(data)
	})

	app.Listen(":3000")
}

then run

curl -X POST -H 'content-type: encoding/json' -d "{name:'John',age:25}" http://localhost:3000/json5
{"Name":"John","Age":25}%
