Fix a hidden problem that came up to the surface on OTP 18.0


Json library for Erlang.


  • eep-0018 style decoded term.
  • can decode map key in atom (default is binary).
  • implemented in NIF.
  • c-style comments acceptable (/* ... */) (default is denied).
  • bigint supported (larger than 64bit word).


$ make

Assuming rebar works for you that should build everything. Yay.


$ make check

Hopefully the tests pass.


Put this app in your Erlang path.

$ erl -pa ebin/
Erlang R15B (erts-5.9) [source] [64-bit] [smp:2:2] [async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.9  (abort with ^G)
1> json:decode(<<"{\"foo\": true}">>).
2> json:encode([true, 1.2, null]).

Yeah. It's that easy.
