# yaml_cpp_struct
[](https://github.com/fantasy-peak/yaml_cpp_struct/actions)
## function
It's a wrapper, It's easy to mapping yaml to cpp's struct
## note
main branch need >= c++17, if you need to use c++11, please use cpp11 branch. cpp11 branch not support std::variant.
Please refer to example for cpp11 branch
## use examples
```
// It relies on two other three open source libraries(yaml-cpp, visit_struct, magic_enum), Please refer to CMakeLists.txt of example
git clone https://github.com/fantasy-peak/yaml_cpp_struct.git
cd ./yaml_cpp_struct/example
mkdir build && cd build
cmake ..
make -j 9
./example ../config.yaml
// use xmake
cd ./yaml_cpp_struct/example
xmake build -v
xmake run example ../../../../config.yaml
```
[Example](./example/main.cpp)
```yaml
