QuqiParser

解析器的基本性质

  • 需要c++20以上版本

Json解析器的使用

json的数据类型

  • enum类型
enum class JValueType
{
	JNull,
	JInt,
	JDouble,
	JBool,
	JString,
	JList,
	JDict
};
  • enum对应下面的数据类型
using null_t 	= bool;
using int_t 	= long long;
using bool_t 	= bool;
using double_t 	= long double;
using string_t 	= std::string;
using list_t 	= std::vector<JObject>;
using dict_t 	= std::unordered_map<std::string, JObject>;

class JObject

  • 类型的定义
//null类型(直接生成)
JObject json;

//int类型(long long)
JObject json = 1;

//double类型(long double)
JObject json = 1.0;

//bool类型(bool)
JObject json = true;

//string类型(std::string)
JObject json = "Hello world!";

//list类型(std::vector<JObject>)
JObject json[0] = 1;
//或者
JObject json.push_back(1);

//dict类型(std::unordered_map<std::string, JObject>)
JObject json["awa"] = 1;
  • 数据的获取
//判断数据类型
json.getType()
返回enum class JValueType

//int类型(long long)
JObject json = 1;
long long get = json.getInt();

//double类型(long double)
long double get = json.getDouble();

//bool类型(bool)
JObject json = true;
bool get = json.getBool();

//string类型(std::string)
JObject json = "Hello world!";
std::string get = json.getString();

//list类型(std::vector<JObject>)
JObject json[0] = 1;

long long get = json[0].getInt();
//or
std::vector<JObject> get = json.getList();
list_t& get = json.getList();

//dict类型(std::unordered_map<std::string, JObject>)
JObject json["awa"] = 1;
long long get = json["awa"].getInt();
//or
std::unordered_map<std::string, JObject> get = json.getDict();
dict_t& get = json.getDict();

class JParser

  • 数据的读取
  1. 读取字符串
string jsonString = R"(
{
    "a":"hello",
    "b":[1,2,3,4],
    "c":false,
    "d":null,
}
)";
JObject json = JParser::fastParse(jsonString);
  1. 读取文件
std::ifstream infile;
JObject json = JParser::fastParse(infile);

class JWriter

  • 数据的写出
JObject json["awa"];
std::string get = JWriter::fastWrite(json);
/*
{"awa":1}
*/

std::string get = JWriter::fastFormatWrite(json);
/*
{
	"awa":1
}
*/

INI解析器的使用

class INIObject

  • 类型的定义和获取
INIObject object;
object["section"]["key"] = "value";
std::string get = object["section"]["key"];

class INIParser

  • 数据的读取
  1. 读取字符串
std::string data = R"(
[server]
address = 127.0.0.1
port = 1234
)");

INIObject object = INIParser::fastParse(data);
  1. 读取文件
std::ifstream file(/*path*/);
INIObject object = INIParser::fastParse(file);

class INIWriter

  • 数据的写出
INIObject object;

std::string get = INIWriter::fastWrite(object);
/*
[server]
address = 127.0.0.1
port = 1234
*/
