# Euneus
An incredibly flexible and performant JSON parser and generator.
Euneus is a rewrite of [Thoas][thoas].
Like Thoas, both the parser and generator fully conform to
[RFC 8259](https://tools.ietf.org/html/rfc8259) and
[ECMA 404](http://www.ecma-international.org/publications/standards/Ecma-404.htm).

## Installation
### Erlang
```erlang
% rebar.config
{deps, [{euneus, "1.0.2"}]}
```
### Elixir
```elixir
# mix.exs
def deps do
[{:euneus, "~> 1.0"}]
end
```
## Basic Usage
```erlang
1> {ok, JSON} = euneus:encode_to_binary(#{name => #{english => <<"Charmander">>, japanese => <<"ヒトカゲ"/utf8>>}, type => [fire], profile => #{height => 0.6, weight => 8}, ability => #{0 => <<"Blaze">>, 1 => undefined}}).
{ok, <<"{\"name\":{\"english\":\"Charmander\",\"japanese\":\"ヒトカゲ\"},\"profile\":{\"height\":0.6,\"weight\":8},\"type\":[\"fire\"],\"ability\":{\"0\":\"Blaze\",\"1\":null}}">>}
2> euneus:decode(JSON).
{ok,#{<<"ability">> =>
#{<<"0">> => <<"Blaze">>,<<"1">> => undefined},
<<"name">> =>
#{<<"english">> => <<"Charmander">>,
<<"japanese">> =>
<<227,131,146,227,131,136,227,130,171,227,130,178>>},
<<"profile">> => #{<<"height">> => 0.6,<<"weight">> => 8},
<<"type">> => [<<"fire">>]}}
3> euneus:decode(JSON, #{
keys => fun
(<<Char>> = Key, _Opts) when Char >= $0, Char =< $9 ->
binary_to_integer(Key);
(Key, _Opts) ->
binary_to_existing_atom(Key)
end
}).
{ok,#{name =>
#{english => <<"Charmander">>,
japanese =>
<<227,131,146,227,131,136,227,130,171,227,130,178>>},
profile => #{height => 0.6,weight => 8},
type => [<<"fire">>],
ability => #{0 => <<"Blaze">>,1 => undefined}}}
```
## Data Mapping
> [!TIP]
>
> More types can be handled by using custom plugins. Please see the [Plugins](#plugins) section for more info.

### Why not more built-in types?
The goal of `Euneus` is to have built-in types that can be commonly encoded and decoded, but the range of types can be easily extended by using plugins. Please see the [Plugins](#plugins) section for more info.
### Note about proplists
Proplists are not handled by Euneus by default.
There are three options:
1. Use the built-in, or create your own, [proplist plugin](#proplist);
2. Convert proplists to maps before the encoding;
3. Override the `list_encoder` option in the encoder to handle them, for example:
```erlang
1> Options = #{
list_encoder => fun
([{K, _} | _] = Proplist, Opts)
when is_binary(K); is_atom(K); is_integer(K) ->
Map = proplists:to_map(Proplist),
euneus_encoder:encode_map(Map, Opts);
(List, Opts) ->
euneus_encoder:encode_list(List, Opts)
end
}.
2> Proplist = [{foo, bar}, {bar, [{0, ok}]}].
3> euneus:encode_to_binary(Proplist, Options).
{ok,<<"{\"foo\":\"bar\",\"bar\":{\"0\":\"ok\"}}">>}
```
The reason for that is because it's impossible to know when a list is a proplist and also because a proplist cannot be decoded. Please see the [Why not more built-in types?](#why-not-more-built-in-types) section for more info about this decision.
## Plugins
Euneus has a mechanism to easily plug in encoders and decoders. You can use the [built-in plugins](#built-in-plugins) to handle common types or create your own in a module by implementing the [euneus_plugin](/src/euneus_plugin.erl) behavior.
If you have a built-in plugin suggestion, feel free to open a [new issue](https://github.com/williamthome/euneus/issues/new) to discuss it.
> [!IMPORTANT]
> The plugins mechanism deprecated the `datetime_encoder` and the `timestamp_encoder` option in favor of the `datetime` and `timestamp` plugins.
### Usage
#### Encode
```erlang
euneus:encode(Term, #{plugins => [
% list of built-in or custom plugins
]})
```
#### Decode
```erlang
euneus:decode(Term, #{plugins => [
% list of built-in or custom plugins
]})
```
### Built-in Plugins
#### datetime
Encodes `calendar:datetime()` to ISO8601 as JSON string and decodes it back, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary({{1970,1,1},{0,0,0}}, #{plugins => [datetime]}).
{ok,<<"\"1970-01-01T00:00:00Z\"">>}
2> euneus:decode(JSON, #{plugins => [datetime]}).
{ok,{{1970,1,1},{0,0,0}}}
```
#### inet
Encodes `inet:ip_address()` to IPV4 or IPV6 as JSON string and decodes it back, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary({127,0,0,1}, #{plugins => [inet]}).
{ok,<<"\"127.0.0.1\"">>}
2> euneus:decode(JSON, #{plugins => [inet]}).
{ok,{127,0,0,1}}
```
#### pid
Encodes `erlang:pid()` to JSON string and decodes it back, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary(list_to_pid("<0.92.0>"), #{plugins => [pid]}).
{ok,<<"\"<0.92.0>\"">>}
2> euneus:decode(JSON, #{plugins => [pid]}).
{ok,<0.92.0>}
```
#### port
Encodes `erlang:port()` to JSON string and decodes it back, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary(list_to_port("#Port<0.1>"), #{plugins => [port]}).
{ok,<<"\"#Port<0.1>\"">>}
2> euneus:decode(JSON, #{plugins => [port]}).
{ok,#Port<0.1>}
```
#### proplist
Encodes `[{binary() | atom() | integer(), term()}]` to JSON object, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary([{foo, bar}], #{plugins => [proplist]}).
{ok,<<"{\"foo\":\"bar\"}">>}
```
#### reference
Encodes `erlang:reference()` to JSON string and decodes it back, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary(make_ref(), #{plugins => [reference]}).
{ok,<<"\"#Ref<0.957048870.857473026.108035>\"">>}
2> euneus:decode(JSON, #{plugins => [reference]}).
{ok,#Ref<0.957048870.857473026.108035>}
```
#### timestamp
Encodes `erlang:timestamp()` to ISO8601 as JSON string and decodes it back, for example:
```erlang
1> {ok, JSON} = euneus:encode_to_binary({0,0,0}, #{plugins => [timestamp]}).
{ok,<<"\"1970-01-01T00:00:00.000Z\"">>}
2> euneus:decode(JSON, #{plugins => [timestamp]}).
{ok,{0,0,0}}
```
## Differences to Thoas
The main difference between `Euneus` to `Thoas` is that Euneus gives more control to encoding or decoding data. All encode functions can be overridden and extended and all decoded data can be overridden and transformed. Also, there is no plugin mechanism in Thoas.
### Encode
Available encode options:
```erlang
#{
%% nulls defines what terms will be replaced with the null literal (default: ['undefined']).
nulls => nonempty_list(),
%% binary_encoder allow override the binary() encoding.
binary_encoder => function((binary(), euneus_encoder:options()) -> iolist()),
%% atom_encoder allow override the atom() encoding.
atom_encoder => function((atom(), euneus_encoder:options()) -> iolist()),
%% integer_encoder allow override the integer() encoding.
integer_encoder => function((integer(), euneus_encoder:options()) -> iolist()),
%% float_encoder allow override the float() encoding.
float_encoder => function((float(), euneus_encoder:options()) -> iolist()),
%% list_encoder allow override the list() encoding.
list_encoder => function((list(), euneus_encoder:options()) -> iolist()),
%% map_encoder allow override the map() encoding.
map_encoder => function((map(), euneus_encoder:options()) -> iolist()),
%% unhandled_encoder allow encode any custom term (default: raise unsupported_type error).
unhandled_encoder => function((term(), euneus_encoder:options()) -> iolist()),
%% escaper allow override the binary escaping (default: json).
escaper => json
| html
| javascript
| unicode
| function((binary(), euneus_encoder:options()) -> iolist()),
error_handler => function(( error | exit | throw
, term()
, erlang:stacktrace() ) -> euneus_encoder:result()),
%% plugins extends the encode types.
plugins => datetime
| inet
| pid
| port
| proplist
| reference
| timestamp
| module() % that implements the `euneus_plugin` behavior.
}
```
For example:
```erlang
1> EncodeOpts = #{
binary_encoder => fun
(<<"foo">>, Opts) ->
euneus_encoder:encode_binary(<<"bar">>, Opts);
(Bin, Opts) ->
euneus_encoder:encode_binary(Bin, Opts)
end,
unhandled_encoder => fun
({_, _, _, _} = Ip, Opts) ->
case inet:ntoa(Ip) of
{error, einval} ->
throw(invalid_ip);
IpStr ->
IpBin = list_to_binary(IpStr),
euneus_encoder:encode_binary(IpBin, Opts)
end;
(Term, Opts) ->
euneus_encoder:throw_unsupported_type_error(Term, Opts)
end,
error_handler => fun
(throw, invalid_ip, _Stacktrace) ->
{error, invalid_ip};
(Class, Reason, Stacktrace) ->
euneus_encoder:handle_error(Class, Reason, Stacktrace)
end
}.
2> Data = #{<<"foo">> => bar, ipv4 => {127,0,0,1}, none => undefined}.
3> euneus:encode_to_binary(Data, EncodeOpts).
{ok, <<"{\"bar\":\"bar\",\"ipv4\":\"127.0.0.1\",\"none\":null}">>}
4> euneus:encode_to_binary({1270,0,0,1}, EncodeOpts).
{error, invalid_ip}
```
### Decode
Available decode options:
```erlang
#{
%% null_term is the null literal override (default: 'undefined').
null_term => term(),
%% arrays allow override any array/list().
arrays => function((list(), euneus_decoder:options()) -> term()),
%% objects allow override any object/map().
objects => function((map(), euneus_decoder:options()) -> term()),
%% keys allow override the keys from JSON objects.
keys => copy
| to_atom
| to_existing_atom
| to_integer
| function((binary(), euneus_decoder:options()) -> term()),
%% values allow override any other term, like array item or object value.
values => copy
| to_atom
| to_existing_atom
| to_integer
| function((binary(), euneus_decoder:options()) -> term()),
%% plugins extends the decode types.
plugins => datetime
| inet
| pid
| port
| reference
| timestamp
| module() % that implements the `euneus_plugin` behavior.
}
```
For example:
```erlang
1> DecodeOpts = #{
null_term => nil,
keys => fun
(<<"bar">>, _Opts) ->
foo;
(Key, _Opts) ->
binary_to_atom(Key)
end,
values => fun
(<<"127.0.0.1">>, _Opts) ->
{127, 0, 0, 1};
(Value, _Opts) ->
Value
end
}.
2> JSON = <<"{\"bar\":\"bar\",\"ipv4\":\"127.0.0.1\",\"none\":null}">>.
3> euneus:decode(JSON, DecodeOpts).
{ok,#{foo => <<"bar">>,
ipv4 => {127,0,0,1},
none => nil}}
```
#### Resuming
Euneus permits resuming the decoding when an invalid token is found. Any value can replace the invalid token by overriding the `error_handler` option, e.g.:
```erlang
1> ErrorHandler = fun
(throw, {{token, Token}, Rest, Opts, Input, Pos, Buffer}, _Stacktrace) ->
Replacement = foo,
euneus_decoder:resume(Token, Replacement, Rest, Opts, Input, Pos, Buffer);
(Class, Reason, Stacktrace) ->
euneus_decoder:handle_error(Class, Reason, Stacktrace)
end.
2> Opts = #{error_handler => ErrorHandler}.
3> euneus:decode(<<"[1e999,1e999,{\"foo\": 1e999}]">>, Opts).
{ok,[foo,foo,#{<<"foo">> => foo}]}
```
> [!NOTE]
>
> By using `euneus_decoder:resume/6` the replacement will be the `null_term` option.
### Why Euneus over Thoas?
`Thoas` is incredible, works performant and perfectly fine, but `Euneus` is more flexible, permitting more customizations, and is more performant than Thoas. See the [benchmarks](#benchmarks).
The motivation for Euneus is [this PR](https://github.com/lpil/thoas/pull/28).
## Benchmarks
All the latest runs details can be found under the [runs](./euneus_bench/runs/) directory in the [benchmark project](./euneus_bench/).
### Encode
#### Smart encoding
This benchmark uses the JSON smart module via the `euneus:encode/1` function. Smart modules only receive the input as the argument, so no option is available to set. Smart modules are the fastest euneus modules.

#### Encoding with empty map as option
This benchmark passes the input and options parsed as the `euneus:encode_parsed/2` function arguments. There is no option set, just an empty map, so all the default options are used. This function it's a bit slower than the smart one, but all options are analyzed in the run.

All benchmark details are available [here](./euneus_bench/runs/encode_parsed.md).
#### Encoding with all built-in plugins
This benchmark passes all the encode built-in plugins to the plugins option:
```erlang
euneus:parse_encode_opts(#{
plugins => [
datetime,
inet,
pid,
port,
proplist,
reference,
timestamp
]
}).
```
It's the slowest euneus encode run, but at the same time it is very efficient.

### Decode
#### Smart decoding
This benchmark uses the decode smart module via the `euneus:decode/1` function. Smart modules only receive the input as the argument, so no option is available to set. Smart modules are the fastest euneus modules.

#### Decoding with empty map as option
This benchmark passes the input and options parsed as the `euneus:decode_parsed/2` function arguments. There is no option set, just an empty map, so all the default options are used. This function it's a bit slower than the smart one, but all options are analyzed in the run.

All benchmark details are available [here](./euneus_bench/runs/decode_parsed.md).
#### Decoding with all built-in plugins
This benchmark passes all the decode built-in plugins to the plugins option:
```erlang
euneus:parse_decode_opts(#{
plugins => [
datetime,
timestamp,
pid,
port,
reference,
inet
]
}).
```
> [!NOTE]
>
> The `proplist` plugin is only available for encoding.
It's the slowest euneus decode run, but at the same time it is very efficient.

All benchmark details are available [here](./euneus_bench/runs/decode_parsed_plugins.md).
## Tests
There are Eunit tests in [euneus_encoder](/src/euneus_encoder.erl) and [euneus_decoder](/src/euneus_decoder.erl) and tests suites in a specific project under the [euneus_test](/euneus_test/) directory. Euneus has more than 330 tests.
Also, the parser is tested using [JSONTestSuite](https://github.com/nst/JSONTestSuite) and all tests passes:
See the [Euneus parser](https://github.com/nst/JSONTestSuite/tree/master/parsers/test_erlang_euneus) in JSONTestSuite.
> [!NOTE]
>
> All of the JSONTestSuite tests are embedded in Euneus tests.
## Smart modules
Euneus has modules that permit customizations and others that use the default options. The modules without customizations are called smart. The smart versions are faster because they do not do any option checks.
If you are good to go with the default options, please use the smart versions:
- Encode:
- `euneus:encode/1` or `euneus_encoder_smart_json:encode/1`;
- `euneus:encode_js/1` or `euneus_encoder_smart_javascript:encode/1`;
- `euneus:encode_html/1` or `euneus_encoder_smart_html:encode/1`;
- `euneus:encode_unicode/1` or `euneus_encoder_smart_unicode:encode/1`;
- Decode:
- `euneus:decode/1` or `euneus_decoder_smart:decode/1`.
## Credits
Euneus is a rewrite of Thoas, so all credits go to [Michał Muskała](https://github.com/michalmuskala), [Louis Pilfold](https://github.com/lpil), also both [Jason][jason] and [Thoas][thoas] contributors. Thanks for the hard work!
## Why the name Euneus?
Euneus is the twin brother of [Thoas](https://en.wikipedia.org/wiki/Thoas_(son_of_Jason)).
