JJSON

Simple library implementation of Javascript Object Notation as described in RFC 8259 # The JavaScript Object Notation (JSON) Data Interchange Format. This library provides parsing and generating of JSON types. This project idea was started based on video session to work on this project https://github.com/rhymu8354/Json, but has diverged largely.

Tests

A suite of tests are provided in the test/ directory. A wide range of test are provided for various JSON parsing , generation and parsing functions.

Building

A simple Make file is provided to build test and library. Operation CMAKE files to be added.

Usage

JSON values are created by call to jjson::value

• null - null value is defined as macro to nullptr

 jjson::value null_value = null;     //null 
 auto null_value = jjson::value(null);  //null
 jjson null_value = jjson::valune(nullptr);  //null

• bool

 jjson::value true_value = true;             //true
 auto false_value = jjson::value(false);     //false

• string

auto jjson_string = jjson::value("jjson string");  //"jjson string"
auto jjson_string = R"("jjson string")";           //"jjson string"
auto jjson_string = jjson_str_t("jjson string");   //"jjson string"

• number

auto jjson_int = jjson::value((int64_t)10);   //10
auto jjson_int_w_exponent = jjson::value((int64_t)10,12); //10e12
auto jjson_float = jjson::value(183.32);    //183.32
auto jjson_float_w_exponent = jjson::value(3.14,-1);      //3.14e-1

• Array

const  auto jjson_array = jjson::Array({ true , null ,false });             //[true , null , false]
const  auto jjson_array = jjson::Array({ "duck" , (int64_t)2 ,"goose" });   //["duck" , 2 , "goose"]
const auto jjson_sub_array = jjson::Array({ "test" , (int64_t)5 });         
auto jjson_nested_array = jjson::Array({ "duck" , (int64_t)2 , jjson_array4 });     //["duck" , 2 , [ "test" , 5 ]]
jjson_nested_array[2]; // ["test",5]

• Object

auto jjson_empty_object = jjson::Object();  //{}
auto jjson_object = jjson::Object();  //{}
auto jjson_array = jjson::Array({ "test" , (int64_t)5 });  //[ "test" , 5 ]
jjson_object["string"] = "string";  //{ "string"  : "string"}
jjson_object["string"] = "new string";    //{ "string" : "new string"}
jjson_object["country"] = "Barbados";     //{ "country" : "Barbados" , "string" : "new string"}
jjson_empty_object["int"] = (int64_t)12;  //{ "int" : 12,}
jjson_object["array"] = jjson_array4;     //{ "array" : [ "test" , 5 ] , "country" : "Barbados" , "string" : "new string"}
jjson_object["object"] = jjson_empty_object;   //{ "array" : [ "test" , 5 ] , "country" : "Barbados" ,"object" : {} , "string" : "new string"}
jjson_object["parish"] = "St. George";     //{ "array" : [ "test" , 5 ] , "country" : "Barbados" ,"object" : {} , "Parish" : "St. George" ,"string" : "new string"}
jjson_object["null"] = null;   //{ "array" : [ "test" , 5 ] , "country" : "Barbados" ,"object" : {} , "null" : null , "Parish" : "St. George" ,"string" : "new string"}

• Parsing and printing

 auto jjson_object_object= jjson::value::parse_from_string(R"({"object1":{},"object2":{"key":"val","array":[{},"string",true]}})");
 jjson_object_object.to_string();   //{"object1":{},"object2":{"key":"val","array":[{},"string",true]}}
