jsonc

jsonc is a Go package that converts the jsonc format to standard json.

The jsonc format is like standard json but with following additional features:

comments, single line (// text) or multiline (/* text */)
trailing commas
replace new line (\n) chars with \\ following by n
replace tabs (\t) chars with \\ following by t
remove invalid escape character of '
escape " in string literals
auto add missing commas

{
  /* Dev Machine */
  "dbInfo": {
    "host": "localhost",
    "port": 5432,          
    "username": "josh",
    "password": "pass123", // please use a hashed password
  },

  "title": "Hello 
    World",
}

Getting Started

Installing

To start using jsonc, install Go and run go get:

$ go get -u github.com/astappiev/jsonc

This will retrieve the library.

Example

There's a provided function jsonc.ToJSON, which does the conversion.

The resulting JSON will always be the same length as the input, and it will include all the same line breaks at matching offsets. This is to ensure the result can be later processed by an external parser and that that parser will report messages or errors with the correct offsets.

The following example uses a JSON document that has comments and trailing commas and converts it just prior to unmarshalling with the standard Go JSON library.

data := `
{
  /* Dev Machine */
  "dbInfo": {
    "host": "localhost",
    "port": 5432,          // use full email address
    "username": "josh",
    "password": "pass123", // use a hashed password
  },
  "title": "Hello 
    World",
}
`

err := json.Unmarshal(jsonc.ToJSON(data), &config)

Performance

It's fast and can convert GB/s of jsonc to json.
