json2cbor - recoder in go

This is a simple json2cbor recoder. All the heavy lifting is done by encoding/json and github.com/ugorji/go/codec.

Usage

package main

import j2c "github.com/jbenet/go-json2cbor"


func main() {
  switch os.Args[1] {
  default:
    return errors.New("arg must be j2c or c2j")
  case "j2c":
    return j2c.JsonToCbor(os.Stdout, os.Stdin)
  case "c2j":
    return j2c.CborToJson(os.Stdout, os.Stdin)
  }
}

json2cbor tool

go get github.com/jbenet/go-json2cbor/json2cbor

convert json to cbor

cat a_bunch_of.json | json2cbor j2c >a_bunch_of.cbor
cat a_bunch_of.cbor | json2cbor c2j >a_bunch_of.json

outputs newline-delimited json.

Test codec with:

random-json -o | json2cbor j2c | json2cbor c2j

Test JSON->CBOR->JSON roundtripping with:

random-json -o -c 10 | tee a.json | json2cbor j2c | json2cbor c2j >b.json && diff a.json b.json
