cpp json utility

Hi there 👋

cppson's Issues

add VS2013 version

improve json parsing

json file parsing is so slow and inefficient, unstable.

toJson pretty

pretty json!

support custom parsing library

meta field remove

FIELD macro create meta_XXX field. remove them.

update README

toJson

instance data to json file

jsoncpp compatibility

add using jsoncpp version.

handle boolean type values which not wrapped with quotes.

In standard json format, json can accept 'null', 'false' and 'true' values. but your implementation cannot parse boolean types which not wrapped with quotes("").

expected result

JSON_CLASS(Foo)
{
public:
  FIELD(bool, b);
}

{
  "b" : true
}

add tests

#define CATCH_CONFIG_MAIN
#include "catch.h"

TEST_CASE("parse from string") {
    JSON_CLASS(NestedObject)
    {
    public:
        FIELD(int, _int);
        FIELD(bool, _bool);
    };
    JSON_CLASS(TestObject)
    {
    public:
        FIELD(int, _int);
        FIELD(bool, _bool);
        //FIELD(float, _float);
        FIELD(std::string, _string);

        FIELD(std::vector<int>, _vector);

        FIELD(NestedObject, _nested);
    };

    TestObject obj;
    obj.ParseFromString(
        "{"
        /* for 'basic types' section */
        "\"_int\" : 5,"
        "\"_bool\" : \"true\","
        //"\"_float\" : 2.5,"
        "\"_string\" : \"hello\","

        /* for 'std::vector type' section */
        "\"_vector\" : [1, 2, 3 ,4 ,5],"

        /* for 'std::map type' section */
        //"\"_vector\" : [1, 2, 3 ,4 ,5],"

        /* for 'nested object' section */
        "\"_nested\" : {"
            "\"_int\" : 14,"
            "\"_bool\" : \"false\""
            "}"
        "}");

    SECTION("basic types") {
        REQUIRE(obj._int == 5);
        REQUIRE(obj._bool == true);
        //REQUIRE(obj._float == 5.0f);
        REQUIRE(obj._string == "hello");
    }
    SECTION("std::vector type") {
        REQUIRE(obj._vector.size() == 5);
        REQUIRE(obj._vector == (std::vector<int>{1, 2, 3, 4, 5}));
    }
    SECTION("std::map type") {
        /* .... */
    }
    SECTION("nested object") {
        REQUIRE(obj._nested._int == 14);
        REQUIRE(obj._nested._bool == false);
    }
}

iheritance

JSON_CLASS can't inherit.
