Yet another JSON (RFC 4627) library for Erlang.

Authors: Bob Ippolito (bob@mochimedia.com).

Description

Yet another JSON (RFC 4627) library for Erlang. mochijson2 works with binaries as strings, arrays as lists (without an {array, _}) wrapper and it only knows how to decode UTF-8 (and ASCII).

JSON terms are decoded as follows (javascript -> erlang):

{"key": "value"} -> {struct, [{<<"key">>, <<"value">>}]}
["array", 123, 12.34, true, false, null] -> [<<"array">>, 123, 12.34, true, false, null]

Strings in JSON decode to UTF-8 binaries in Erlang
Objects decode to {struct, PropList}
Numbers decode to integer or float
true, false, null decode to their respective terms.

The encoder will accept the same format that the decoder will produce, but will also allow additional cases for leniency:

atoms other than true, false, null will be considered UTF-8 strings (even as a proplist key)
{json, IoList} will insert IoList directly into the output with no validation
{array, Array} will be encoded as Array (legacy mochijson style)
A non-empty raw proplist will be encoded as an object as long as the first pair does not have an atom key of json, struct, or array

Function Index

decode/1	Decode the given iolist to Erlang terms.
decode/2	Decode the given iolist to Erlang terms using the given object format for decoding, where proplist returns JSON objects as [{binary(), json_term()}] proplists, eep18 returns JSON objects as {[binary(), json_term()]}, and struct returns them as-is.
decoder/1	Create a decoder/1 with the given options.
encode/1	Encode the given as JSON to an iolist.
encoder/1	Create an encoder/1 with the given options.

Function Details

decode/1

decode(S) -> any()

Decode the given iolist to Erlang terms.

Decode the given iolist to Erlang terms using the given object format for decoding, where proplist returns JSON objects as [{binary(), json_term()}] proplists, eep18 returns JSON objects as {[binary(), json_term()]}, and struct returns them as-is.

decoder/1

decoder(Options) -> any()

Create a decoder/1 with the given options.

encode/1

encode(Any) -> any()

Encode the given as JSON to an iolist.

encoder/1

encoder(Options) -> any()

Create an encoder/1 with the given options. Emit unicode as utf8 (default - false)
