Status and rights

This module does its job but there is a lot which could (but probably won't) be improved.

Do with it whatever you want. I claim no rights to it.

Motivation

Parsing JSON in erlang is IMHO not at all a straightforward thing to do. I wanted to have something that is similar to the javascript syntax of simply saying "jsonString.member.submember".

Therefore I wrote this parser which allows you to access a member of a JSON object by simply saying: jdec:get(JsonString, ".member.submember").

Additionally I added a few related functions to make the access even more comfortable.

Release process

1. Copy the files to your project

Usage

JSON1 = {
          \"meta_schema_name\": \"real\",
          \"meta_schema_version\": 1,
          \"comments\": [
            \"Bernhard\",
            \"Tina\"
          ],
          \"identifier\": {
            \"asset\": 45,
            \"aspect\": 12
          },
          \"payload\": {
            \"payload_schema_name\": \"real\",
            \"payload_schema_version\": 1,
            \"id\": 123,
            \"time\": \"2011-05-14T14:45:12.435691\",
            \"data\": {
              \"real\": 23.56456
            }
          }
        }.


jdec:get(  JSON1, ".identifier.asset") -> [45] 
jdec:get_s(JSON1, ".identifier.asset") -> 45 

• Have a look at the *_test functions in jdec.erl for further examples

Comments

• This module is not optimized for speed.

• mochijson.erl is included as the JSON-Decoder and does most of the work. I justed added the parser for the dot syntax.
