wson

fast tiny binary json libaray inspired by bson and message pack，less than 1000 line code you can embed in your application with super speed to transfer data.

wson data format

type	signature	format
number int	'i'	signature + varint
number double	'd'	signature + 8 byte (big endian)
number float	'F'	signature + 4 byte (big endian)
string	's'	signature + var length + bytes( unicoder utf-16)
null	'0'	signature
boolean	't' or 'f'	signature
array	'['	signature + var length + elements
map	'{'	signature + var size + key, value, key, value

string length, map size ar store used usigned varint.

here is an example, data in json as follows:

{
  "name" : "hello world"
}

in wson

1 quick start c++

1.1 include header file

  #include "wson/wson_parser.h"

1.2 read object map example

  const char* data = readFile("data.wson"); // binary wson data from some where
  wson_parser parser(data);
  int type = parser.nextType();
  if(parser.isMap(type)){
      int size = parser.nextMapSize();
      for(int i=0; i<size; i++){
          std::string key = parser.nextMapKeyUTF8();
          uint8_t  valueType = parser.nextType();
          std::string value = parser.nextStringUTF8(valueType);
          printf("map %s == %s \n", key.c_str(), value.c_str());
      }
  }

1.3 read object array example

 const char* data = readFile("data.wson"); // binary wson data from some where
  wson_parser parser(data);
  int type = parser.nextType();
  if(parser.isArray(type)){
    int size = parser.nextArraySize();
    for(int i=0; i<size; i++){
        uint8_t  valueType = parser.nextType();
        std::string value = parser.nextStringUTF8(valueType);
        printf("array %d == %s \n", i, value.c_str());
    }
  }

2 quick start java

2.1 convert java object to wson binary

Person person = new Person();
byte[] bts = Wson.toWson(person);

2.2 convert wson java object

byte[] bts = readFile("person.wson");
Map map = (Map)Wson.parse(bts);
