ioke-json provides serialization and de-serialization to JSON for Ioke objects.

Important

This is a proof of concept implementation. It evaluates JSON code as Ioke code which is DANGEROUS and should be used to parse trusted content only.

Requirements

• Supports ikj only.
• Needs following patches to Ioke: http://github.com/bragi/ioke/tree/java_based_extensions, http://github.com/bragi/ioke/tree/dict_removeAt, http://github.com/bragi/ioke/tree/use_from_jar_file

Building

Clone the repository in the same directory where you have ioke installed:

git clone git://github.com/bragi/ioke-json.git

You should have following directory structure:

ioke/
  bin/
  build/
  ...
ioke-json/
  lib/
  src/
  ...

Run ant:

ant

Extension will be built in ioke-json/lib/ioke-json-1.1.0.jar

Usage

Put ioke-json-1.1.0.jar in you load path. In you .ik file do:

use("ioke-json-1.1.0.jar")

Then following works:

true toJson # => "true"
"json" toJson # => "\"json\""
{0 => 1, "a" => "b"} toJson # => "{0 : 1, \"a\" : \"b\"}"
Origin mimic toJson # => "{\"kind\" : \"Origin\"}"

De-serialization is supported as well:

JSON fromText("[]") # => list
JSON fromText("{}") # =>  dict
JSON fromText("{\"kind\" : \"Origin\"}") # => {"kind" => "Origin"}
