# 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
```cpp
enum class JValueType
{
JNull,
JInt,
JDouble,
JBool,
JString,
JList,
JDict
};
```
- enum对应下面的数据类型
```cpp
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;
using dict_t = std::unordered_map;
```
### class JObject
- 类型的定义
```cpp
//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 json[0] = 1;
//或者
JObject json.push_back(1);
//dict类型（std::unordered_map）
JObject json["awa"] = 1;
```
- 数据的获取
```cpp
//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 json[0] = 1;
long long get = json[0].getInt();
//or
std::vector get = json.getList();
list_t& get = json.getList();
//dict类型（std::unordered_map）
JObject json["awa"] = 1;
long long get = json["awa"].getInt();
//or
std::unordered_map get = json.getDict();
dict_t& get = json.getDict();
```
### class JParser
- 数据的读取
1. 读取字符串
```cpp
string jsonString = R"(
{
"a":"hello",
"b":[1,2,3,4],
"c":false,
"d":null,
}
)";
JObject json = JParser::fastParse(jsonString);
```
2. 读取文件
```cpp
std::ifstream infile;
JObject json = JParser::fastParse(infile);
```
### class JWriter
- 数据的写出
```cpp
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
```cpp
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
```cpp
std::string data = R"(
[server]
address = 127.0.0.1
port = 1234
)");
INIObject object = INIParser::fastParse(data);
```
2. 读取文件
```cpp
std::ifstream file(/*path*/);
INIObject object = INIParser::fastParse(file);
```
### class INIWriter
- 数据的写出
```cpp
INIObject object;
std::string get = INIWriter::fastWrite(object);
/*
[server]
address = 127.0.0.1
port = 1234
*/
```
