JSON for Elixir

Encoding

JSON.encode [ok: true] #=> "{\"ok\":true}"

Decoding

JSON.decode "{\"ok\":true}" #=> [{"ok",true}]

Custom encoder/decoders

defmodule MyJSON do
  use JSON

  def pre_encoder(:undefined), do: :null
  def pre_encoder(value), 	   do: super(value)

  def post_decoder(null),  do: :undefined
  def post_decoder(value), do: super(value)
end

jsonex's Issues

json from nested list

When I have list with nested list elements
[query: [filtered: [query: [term: ["name.first": "shay"]], filter: [or: [filters: [[range: [postDate: [from: "2010-03-01", to: "2010-04-01"]]],[prefix: ["name.second": "ba"]]], _cache: true]]]]]

Then I get
{"query":{"filtered":{"filter":{"or":{"_cache":true,"filters":[{"range":{"postDate":{"from":"2010-03-01","to":"2010-04-01"}}},{"prefix":{"name.second":"ba"}}]}},"query":{"term":{"name.first":"shay"}}}}}

Incompatible with Elixir 0.14

You're using the old sigil syntax, %r for regular expressions, instead of the current ~r, which gives a compilation error:

> mix deps.compile jsonex
* Compiling jsonex

== Compilation error on file lib/json/decoder.ex ==

    (elixir) lib/kernel/parallel_compiler.ex:91: anonymous fn/3 in Kernel.ParallelCompiler.spawn_compilers/8

If I fix the regexes, then I get this error

Error in JSON.decode when json key has three '-' or two '-'

  json = '{"_id": "id", "title": "Pick-Me-Up"}'
  assert_raise JSON.DecodeError, "cannot decode", fn ->

README typo

null –> :null in post_decoder function

Broken compile on Travis

When I compile jsonex in my project on Travis I got this error:
jsonex/lib/json.ex:12: function function/2 undefined
