# `json5`
**`json5`** is a small header only C++ library for parsing [JSON](https://en.wikipedia.org/wiki/JSON) or [**JSON5**](https://json5.org/) data. It also comes with a simple reflection system for easy serialization and deserialization of C++ structs.

### Quick Example:
```cpp
#include <json5/json5_input.hpp>
#include <json5/json5_output.hpp>

struct Settings
{
	int x = 0;
	int y = 0;
	int width = 0;
	int height = 0;
	bool fullscreen = false;
	std::string renderer = "";

JSON5_MEMBERS(x, y, width, height, fullscreen, renderer)
};

Settings s;

// Fill 's' instance from file
json5::from_file("settings.json", s);

// Save 's' to file
json5::to_file("settings.json", s);
```

## `json5.hpp`
TBD

## `json5_input.hpp`
Provides functions to load `json5::document` from string, stream or file.

## `json5_output.hpp`
Provides functions to convert `json5::document` into string, stream or file.

## `json5_builder.hpp`

## `json5_reflect.hpp`

### Basic supported types:
- `bool`
- `int`, `float`, `double`
- `std::string`
- `std::vector`, `std::map`, `std::unordered_map`, `std::array`
- `C array`

## `json5_base.hpp`

## `json5_filter.hpp`

TBD

# Additional examples

### Serialize custom type:
```cpp
// Let's have a 3D vector struct:
struct vec3 { float x, y, z; };

// Let's have a triangle struct with 'vec3' members
struct Triangle
{
	vec3 a, b, c;
};

JSON5_CLASS(Triangle, a, b, c)

namespace json5::detail {

// Write vec3 as JSON array of 3 numbers
inline json5::value write( writer &w, const vec3 &in )
{
	w.push_array();
	w += write( w, in.x );
	w += write( w, in.y );
	w += write( w, in.z );
	return w.pop();
}

// Read vec3 from JSON array
inline error read( const json5::value &in, vec3 &out )
{
	return read( json5::array_view( in ), out.x, out.y, out.z );
}

} // namespace json5::detail
```

### Serialize enum:
```cpp
enum class MyEnum
{
	Zero,
	First,
	Second,
	Third
};

// (must be placed in global namespce, requires C++20)
JSON5_ENUM( MyEnum, Zero, First, Second, Third )
```
