JSON with comments for Go!

JSONC is a superset of JSON which supports comments. JSON formatted files are readable to humans but the lack of comments decreases readability. With JSONC, you can use block (/* */) and single line (// of #) comments to describe the functionality. Microsoft VS Code also uses this format in their configuration files like settings.json, keybindings.json, launch.json, etc.

What this package offers

JSONC for Go offers ability to convert and unmarshal JSONC to pure JSON. It also provides functionality to read JSONC file from disk and return JSONC and corresponding JSON encoding to operate on. However, it only provides a one way conversion. That is, you can not generate JSONC from JSON. Read documentation for detailed examples.

Usage

go get it

Run go get command to install the package.

$ go get github.com/df-mc/jsonc

Import jsonc

Import github.com/df-mc/jsonc to your source file.

package main

import (
  "fmt"

  "github.com/df-mc/jsonc"
)

Test it

Now test it!

func main() {
  j := []byte(`{"foo": /*comment*/ "bar"}`)
  jc := jsonc.ToJSON(j) // Calling jsonc.ToJSON() to convert JSONC to JSON
  if jsonc.Valid(jc) {
    fmt.Println(string(jc))
  } else {
    fmt.Println("Invalid JSONC")
  }
}

$ go run app.go
{"foo":"bar"}

Functions

func ReadFromFile

func ReadFromFile(filename string) ([]byte, []byte, error)

ReadFromFile reads jsonc file and returns JSONC and JSON encodings

func ToJSON

func ToJSON(b []byte) []byte

ToJSON returns JSON equivalent of JSON with comments

func Unmarshal

func Unmarshal(data []byte, v interface{}) error

Unmarshal parses the JSONC-encoded data and stores the result in the value pointed to by v. Equivalent of calling `json.Unmarshal(jsonc.ToJSON(data), v)`

func UnmarshalLenient

func UnmarshalLenient(data []byte, v interface{}) error

UnmarshalLenient parses JSONC (JSON with comments) into v, stripping comments and decoding only the first valid JSON value. This uses a json.NewDecoder which ignores trailing data, it will only read the first valid JSON value. Equivalent of calling `json.NewDecoder(bytes.NewReader(jsonc.ToJSON(data))).Decode(v)`

func Valid

func Valid(data []byte) bool

Valid reports whether data is a valid JSONC encoding or not
