README
# yaml-cpp  [](https://codedocs.xyz/jbeder/yaml-cpp/)
`yaml-cpp` is a [YAML](http://www.yaml.org/) parser and emitter in C++ matching the [YAML 1.2 spec](http://www.yaml.org/spec/1.2/spec.html).
## Usage
See [Tutorial](https://github.com/jbeder/yaml-cpp/wiki/Tutorial) and [How to Emit YAML](https://github.com/jbeder/yaml-cpp/wiki/How-To-Emit-YAML) for reference. For the old API (until 0.5.0), see [How To Parse A Document](https://github.com/jbeder/yaml-cpp/wiki/How-To-Parse-A-Document-(Old-API)).
## Any Problems?
If you find a bug, post an [issue](https://github.com/jbeder/yaml-cpp/issues)! If you have questions about how to use yaml-cpp, please post it on http://stackoverflow.com and tag it [`yaml-cpp`](http://stackoverflow.com/questions/tagged/yaml-cpp).
## How to Build
`yaml-cpp` uses [CMake](http://www.cmake.org) to support cross-platform building. Install [CMake](http://www.cmake.org) _(Resources -> Download)_ before proceeding. The basic steps to build are:
**Note:** If you don't use the provided installer for your platform, make sure that you add `CMake`'s bin folder to your path.
#### 1. Navigate into the source directory, create build folder and run `CMake`:
```sh
mkdir build
cd build
cmake [-G generator] [-DYAML_BUILD_SHARED_LIBS=on|OFF] ..
```
* The `generator` option is the build system you'd like to use. Run `cmake` without arguments to see a full list of available generators.
* On Windows, you might use "Visual Studio 12 2013" (VS 2013 32-bits), or "Visual Studio 14 2015 Win64" (VS 2015 64-bits).
* On OS X, you might use "Xcode".
* On a UNIX-like system, omit the option (for a Makefile).
* `yaml-cpp` builds a static library by default, you may want to build a shared library by specifying `-DYAML_BUILD_SHARED_LIBS=ON`.
* [Debug mode of the GNU standard C++
library](https://gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode.html)
can be used when both `yaml-cpp` and client code is compiled with the
`_GLIBCXX_DEBUG` flag (e.g. by calling CMake with `-D
CMAKE_CXX_FLAGS_DEBUG='-g -D_GLIBCXX_DEBUG'` option).
Note that for `yaml-cpp` unit tests to run successfully, the _GoogleTest_
library also must be built with this flag, i.e. the system one cannot be
used (the _YAML_USE_SYSTEM_GTEST_ CMake option must be _OFF_, which is the
default).
* For more options on customizing the build, see the [CMakeLists.txt](https://github.com/jbeder/yaml-cpp/blob/master/CMakeLists.txt) file.
#### 2. Build it!
* The command you'll need to run depends on the generator you chose earlier.
**Note:** To clean up, just remove the `build` directory.
## How to Integrate it within your project using CMake
You can use for example FetchContent :
```cmake
include(FetchContent)
FetchContent_Declare(
yaml-cpp
GIT_REPOSITORY https://github.com/jbeder/yaml-cpp.git
GIT_TAG # Can be a tag (yaml-cpp-x.x.x), a commit hash, or a branch name (master)
)
FetchContent_MakeAvailable(yaml-cpp)
target_link_libraries(YOUR_LIBRARY PUBLIC yaml-cpp::yaml-cpp) # The library or executable that require yaml-cpp library
```
## Recent Releases
[yaml-cpp 0.8.0](https://github.com/jbeder/yaml-cpp/releases/tag/yaml-cpp-0.8.0) released!
[yaml-cpp 0.3.0](https://github.com/jbeder/yaml-cpp/releases/tag/release-0.3.0) is still available if you want the old API.
**The old API will stop receiving bugfixes in 2026.** The 0.3.x versions provide the old API, and 0.5.x and above all provide the new API.
