# Style
This project is formatted with [clang-format][fmt] using the style file at the root of the repository. Please run clang-format before sending a pull request.
In general, try to follow the style of surrounding code. We mostly follow the [Google C++ style guide][cpp-style].
Commit messages should be in the imperative mood, as described in the [Git contributing file][git-contrib]:
> Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
> instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
> to do frotz", as if you are giving orders to the codebase to change
> its behaviour.

# Tests
Please verify the tests pass by configuring CMake with `-D YAML_CPP_BUILD_TESTS=ON` and running the target `test/yaml-cpp-tests`.
If you are adding functionality, add tests accordingly. Note that the "spec tests" are reserved for examples directly from the YAML spec, so if you have new examples, put them in other test files.
# Pull request process
Every pull request undergoes a code review. Unfortunately, github's code review process isn't great, but we'll manage. During the code review, if you make changes, add new commits to the pull request for each change. Once the code review is complete, rebase against the master branch and squash into a single commit.

# yaml-cpp ![Build Status](https://github.com/jbeder/yaml-cpp/actions/workflows/build.yml/badge.svg) [![Documentation](https://codedocs.xyz/jbeder/yaml-cpp.svg)](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

## 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 <tag_name> # 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 following is a list of breaking changes to yaml-cpp, by version #
# New API #
## HEAD ##
* Throws an exception when trying to parse a negative number as an unsigned integer.
* Supports the `as<int8_t>`/`as<uint8_t>`, which throws an exception when the value exceeds the range of `int8_t`/`uint8_t`.
## 0.6.0 ##
* Requires C++11.
## 0.5.3 ##
_none_
## 0.5.2 ##
_none_
## 0.5.1 ##
* `Node::clear` was replaced by `Node::reset`, which takes an optional node, similar to smart pointers.
## 0.5.0 ##
Initial version of the new API.
# Old API #
## 0.3.0 ##
_none_
## 0.2.7 ##
* `YAML::Binary` now takes `const unsigned char *` for the binary data (instead of `const char *`).
## 0.2.6 ##
* `Node::GetType()` is now `Node::Type()`, and returns an enum `NodeType::value`, where:
> > ` struct NodeType { enum value { Null, Scalar, Sequence, Map }; }; `
* `Node::GetTag()` is now `Node::Tag()`
* `Node::Identity()` is removed, and `Node::IsAlias()` and `Node::IsReferenced()` have been merged into `Node::IsAliased()`. The reason: there's no reason to distinguish an alias node from its anchor - whichever happens to be emitted first will be the anchor, and the rest will be aliases.
* `Node::Read<T>` is now `Node::to<T>`. This wasn't a documented function, so it shouldn't break anything.
* `Node`'s comparison operators (for example, `operator == (const Node&, const T&)`) have all been removed. These weren't documented either (they were just used for the tests), so this shouldn't break anything either.
* The emitter no longer produces the document start by default - if you want it, you can supply it with the manipulator `YAML::BeginDoc`.
## 0.2.5 ##
This wiki was started with v0.2.5.

# Basic Emitting #
The model for emitting YAML is `std::ostream` manipulators. A `YAML::Emitter` objects acts as an output stream, and its output can be retrieved through the `c_str()` function (as in `std::string`). For a simple example:
```cpp
#include "yaml-cpp/yaml.h"
int main()
{
YAML::Emitter out;
out << "Hello, World!";
std::cout << "Here's the output YAML:\n" << out.c_str(); // prints "Hello, World!"
return 0;
}
```
# Simple Lists and Maps #
A `YAML::Emitter` object acts as a state machine, and we use manipulators to move it between states. Here's a simple sequence:
```cpp
YAML::Emitter out;
out << YAML::BeginSeq;
out << "eggs";
out << "bread";
out << "milk";
out << YAML::EndSeq;
```
produces
```yaml
- eggs
- bread
- milk
```
A simple map:
```cpp
YAML::Emitter out;
out << YAML::BeginMap;
out << YAML::Key << "name";
out << YAML::Value << "Ryan Braun";
out << YAML::Key << "position";
out << YAML::Value << "LF";
out << YAML::EndMap;
```
produces
```yaml
name: Ryan Braun
position: LF
```
These elements can, of course, be nested:
```cpp
YAML::Emitter out;
out << YAML::BeginMap;
out << YAML::Key << "name";
out << YAML::Value << "Barack Obama";
out << YAML::Key << "children";
out << YAML::Value << YAML::BeginSeq << "Sasha" << "Malia" << YAML::EndSeq;
out << YAML::EndMap;
```
produces
```yaml
name: Barack Obama
children:
- Sasha
- Malia
```
# Using Manipulators #
To deviate from standard formatting, you can use manipulators to modify the output format. For example,
```cpp
YAML::Emitter out;
out << YAML::Literal << "A\n B\n C";
```
produces
```yaml
|
A
B
C
```
and
```cpp
YAML::Emitter out;
out << YAML::Flow;
out << YAML::BeginSeq << 2 << 3 << 5 << 7 << 11 << YAML::EndSeq;
```
produces
```yaml
[2, 3, 5, 7, 11]
```
Comments act like manipulators:
```cpp
YAML::Emitter out;
out << YAML::BeginMap;
out << YAML::Key << "method";
out << YAML::Value << "least squares";
out << YAML::Comment("should we change this method?");
out << YAML::EndMap;
```
produces
```yaml
method: least squares # should we change this method?
```
And so do aliases/anchors:
```cpp
YAML::Emitter out;
out << YAML::BeginSeq;
out << YAML::Anchor("fred");
out << YAML::BeginMap;
out << YAML::Key << "name" << YAML::Value << "Fred";
out << YAML::Key << "age" << YAML::Value << "42";
out << YAML::EndMap;
out << YAML::Alias("fred");
out << YAML::EndSeq;
```
produces
```yaml
- &fred
name: Fred
age: 42
- *fred
```
# STL Containers, and Other Overloads #
We overload `operator <<` for `std::vector`, `std::list`, and `std::map`, so you can write stuff like:
{% raw %}
```cpp
std::vector <int> squares = {1, 4, 9, 16};
std::map <std::string, int> ages = {{"Daniel", 26}, {"Jesse", 24}};
YAML::Emitter out;
out << YAML::BeginSeq;
out << YAML::Flow << squares;
out << ages;
out << YAML::EndSeq;
```
{% endraw %}
produces
```yaml
- [1, 4, 9, 16]
-
Daniel: 26
Jesse: 24
```
Of course, you can overload `operator <<` for your own types:
```cpp
struct Vec3 { int x; int y; int z; };
YAML::Emitter& operator << (YAML::Emitter& out, const Vec3& v) {
out << YAML::Flow;
out << YAML::BeginSeq << v.x << v.y << v.z << YAML::EndSeq;
return out;
}
```
and it'll play nicely with everything else.
# Using Existing Nodes #
We also overload `operator << ` for `YAML::Node`s in both APIs, so you can output existing Nodes. Of course, Nodes in the old API are read-only, so it's tricky to emit them if you want to modify them. So use the new API!
# Output Encoding #
The output is always UTF-8. By default, yaml-cpp will output as much as it can without escaping any characters. If you want to restrict the output to ASCII, use the manipulator `YAML::EscapeNonAscii`:
```cpp
emitter.SetOutputCharset(YAML::EscapeNonAscii);
```
# Lifetime of Manipulators #
Manipulators affect the **next** output item in the stream. If that item is a `BeginSeq` or `BeginMap`, the manipulator lasts until the corresponding `EndSeq` or `EndMap`. (However, within that sequence or map, you can override the manipulator locally, etc.; in effect, there's a "manipulator stack" behind the scenes.)
If you want to permanently change a setting, there are global setters corresponding to each manipulator, e.g.:
```cpp
YAML::Emitter out;
out.SetIndent(4);
out.SetMapStyle(YAML::Flow);
```
# When Something Goes Wrong #
If something goes wrong when you're emitting a document, it must be something like forgetting a `YAML::EndSeq`, or a misplaced `YAML::Key`. In this case, emitting silently fails (no more output is emitted) and an error flag is set. For example:
```cpp
YAML::Emitter out;
assert(out.good());
out << YAML::Key;
assert(!out.good());
std::cout << "Emitter error: " << out.GetLastError() << "\n";
```

_The following describes the old API. For the new API, see the [Tutorial](https://github.com/jbeder/yaml-cpp/wiki/Tutorial)._
## Contents ##
# Basic Parsing #
The parser accepts streams, not file names, so you need to first load the file. Since a YAML file can contain many documents, you can grab them one-by-one. A simple way to parse a YAML file might be:
```
#include <fstream>
#include "yaml-cpp/yaml.h"
int main()
{
std::ifstream fin("test.yaml");
YAML::Parser parser(fin);
YAML::Node doc;
while(parser.GetNextDocument(doc)) {
// ...
}
return 0;
}
```
# Reading From the Document #
Suppose we have a document consisting only of a scalar. We can read that scalar like this:
```
YAML::Node doc; // let's say we've already parsed this document
std::string scalar;
doc >> scalar;
std::cout << "That scalar was: " << scalar << std::endl;
```
How about sequences? Let's say our document now consists only of a sequences of scalars. We can use an iterator:
```
YAML::Node doc; // already parsed
for(YAML::Iterator it=doc.begin();it!=doc.end();++it) {
std::string scalar;
*it >> scalar;
std::cout << "Found scalar: " << scalar << std::endl;
}
```
... or we can just loop through:
```
YAML::Node doc; // already parsed
for(unsigned i=0;i<doc.size();i++) {
std::string scalar;
doc[i] >> scalar;
std::cout << "Found scalar: " << scalar << std::endl;
}
```
And finally maps. For now, let's say our document is a map with all keys/values being scalars. Again, we can iterate:
```
YAML::Node doc; // already parsed
for(YAML::Iterator it=doc.begin();it!=doc.end();++it) {
std::string key, value;
it.first() >> key;
it.second() >> value;
std::cout << "Key: " << key << ", value: " << value << std::endl;
}
```
Note that dereferencing a map iterator is undefined; instead, use the `first` and `second` methods to get the key and value nodes, respectively.
Alternatively, we can pick off the values one-by-one, if we know the keys:
```
YAML::Node doc; // already parsed
std::string name;
doc["name"] >> name;
int age;
doc["age"] >> age;
std::cout << "Found entry with name '" << name << "' and age '" << age << "'\n";
```
One thing to be keep in mind: reading a map by key (as immediately above) requires looping through all entries until we find the right key, which is an O(n) operation. So if you're reading the entire map this way, it'll be O(n^2). For small n, this isn't a big deal, but I wouldn't recommend reading maps with a very large number of entries (>100, say) this way.
## Optional Keys ##
If you try to access a key that doesn't exist, `yaml-cpp` throws an exception (see [When Something Goes Wrong](https://github.com/jbeder/yaml-cpp/wiki/How-To-Parse-A-Document-(Old-API)#When_Something_Goes_Wrong). If you have optional keys, it's often easier to use `FindValue` instead of `operator[]`:
```
YAML::Node doc; // already parsed
if(const YAML::Node *pName = doc.FindValue("name")) {
std::string name;
*pName >> name;
std::cout << "Key 'name' exists, with value '" << name << "'\n";
} else {
std::cout << "Key 'name' doesn't exist\n";
}
```
# Getting More Complicated #
The above three methods can be combined to read from an arbitrary document. But we can make life a lot easier. Suppose we're reading 3-vectors (i.e., vectors with three components), so we've got a structure looking like this:
```
struct Vec3 {
float x, y, z;
};
```
We can read this in one operation by overloading the extraction (>>) operator:
```
void operator >> (const YAML::Node& node, Vec3& v)
{
node[0] >> v.x;
node[1] >> v.y;
node[2] >> v.z;
}
// now it's a piece of cake to read it
YAML::Node doc; // already parsed
Vec3 v;
doc >> v;
std::cout << "Here's the vector: (" << v.x << ", " << v.y << ", " << v.z << ")\n";
```
# A Complete Example #
Here's a complete example of how to parse a complex YAML file:
`monsters.yaml`
```
- name: Ogre
position: [0, 5, 0]
powers:
- name: Club
damage: 10
- name: Fist
damage: 8
- name: Dragon
position: [1, 0, 10]
powers:
- name: Fire Breath
damage: 25
- name: Claws
damage: 15
- name: Wizard
position: [5, -3, 0]
powers:
- name: Acid Rain
damage: 50
- name: Staff
damage: 3
```
`main.cpp`
```
#include "yaml-cpp/yaml.h"
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
// our data types
struct Vec3 {
float x, y, z;
};
struct Power {
std::string name;
int damage;
};
struct Monster {
std::string name;
Vec3 position;
std::vector <Power> powers;
};
// now the extraction operators for these types
void operator >> (const YAML::Node& node, Vec3& v) {
node[0] >> v.x;
node[1] >> v.y;
node[2] >> v.z;
}
void operator >> (const YAML::Node& node, Power& power) {
node["name"] >> power.name;
node["damage"] >> power.damage;
}
void operator >> (const YAML::Node& node, Monster& monster) {
node["name"] >> monster.name;
node["position"] >> monster.position;
const YAML::Node& powers = node["powers"];
for(unsigned i=0;i<powers.size();i++) {
Power power;
powers[i] >> power;
monster.powers.push_back(power);
}
}
int main()
{
std::ifstream fin("monsters.yaml");
YAML::Parser parser(fin);
YAML::Node doc;
parser.GetNextDocument(doc);
for(unsigned i=0;i<doc.size();i++) {
Monster monster;
doc[i] >> monster;
std::cout << monster.name << "\n";
}
return 0;
}
```
# When Something Goes Wrong #
... we throw an exception (all exceptions are derived from `YAML::Exception`). If there's a parsing exception (i.e., a malformed YAML document), we throw a `YAML::ParserException`:
```
try {
std::ifstream fin("test.yaml");
YAML::Parser parser(fin);
YAML::Node doc;
parser.GetNextDocument(doc);
// do stuff
} catch(YAML::ParserException& e) {
std::cout << e.what() << "\n";
}
```
If you make a programming error (say, trying to read a scalar from a sequence node, or grabbing a key that doesn't exist), we throw some kind of `YAML::RepresentationException`. To prevent this, you can check what kind of node something is:
```
YAML::Node node;
YAML::NodeType::value type = node.Type(); // should be:
// YAML::NodeType::Null
// YAML::NodeType::Scalar
// YAML::NodeType::Sequence
// YAML::NodeType::Map
```
# Note about copying `YAML::Node` #
Currently `YAML::Node` is non-copyable, so you need to do something like
```
const YAML::Node& node = doc["whatever"];
```
This is intended behavior. If you want to copy a node, use the `Clone` function:
```
std::auto_ptr<YAML::Node> pCopy = myOtherNode.Clone();
```
The intent is that if you'd like to keep a `YAML::Node` around for longer than the document will stay in scope, you can clone it and store it as long as you like.

# Encodings and `yaml-cpp` #
`yaml-cpp` will parse any file as specified by the [YAML 1.2 spec](http://www.yaml.org/spec/1.2/spec.html#id2570322). Internally, it stores all strings in UTF-8, and representation is done with UTF-8. This means that in
```
std::string str;
node >> str;
```
`str` will be UTF-8. Similarly, if you're accessing a map by string key, you need to pass the key in UTF-8. If your application uses a different encoding, you need to convert to and from UTF-8 to work with `yaml-cpp`. (It's possible we'll add some small conversion functions, but for now it's restricted.)

# Introduction #
A typical example, loading a configuration file, might look like this:
```cpp
YAML::Node config = YAML::LoadFile("config.yaml");
if (config["lastLogin"]) {
std::cout << "Last logged in: " << config["lastLogin"].as<DateTime>() << "\n";
}
const std::string username = config["username"].as<std::string>();
const std::string password = config["password"].as<std::string>();
login(username, password);
config["lastLogin"] = getCurrentDateTime();
std::ofstream fout("config.yaml");
fout << config;
```
# Basic Parsing and Node Editing #
All nodes in a YAML document (including the root) are represented by `YAML::Node`. You can check what kind it is:
```cpp
YAML::Node node = YAML::Load("[1, 2, 3]");
assert(node.Type() == YAML::NodeType::Sequence);
assert(node.IsSequence()); // a shortcut!
```
Collection nodes (sequences and maps) act somewhat like STL vectors and maps:
```cpp
YAML::Node primes = YAML::Load("[2, 3, 5, 7, 11]");
for (std::size_t i=0;i<primes.size();i++) {
std::cout << primes[i].as<int>() << "\n";
}
// or:
for (YAML::const_iterator it=primes.begin();it!=primes.end();++it) {
std::cout << it->as<int>() << "\n";
}
primes.push_back(13);
assert(primes.size() == 6);
```
and
```cpp
YAML::Node lineup = YAML::Load("{1B: Prince Fielder, 2B: Rickie Weeks, LF: Ryan Braun}");
for(YAML::const_iterator it=lineup.begin();it!=lineup.end();++it) {
std::cout << "Playing at " << it->first.as<std::string>() << " is " << it->second.as<std::string>() << "\n";
}
lineup["RF"] = "Corey Hart";
lineup["C"] = "Jonathan Lucroy";
assert(lineup.size() == 5);
```
Querying for keys does **not** create them automatically (this makes handling optional map entries very easy)
```cpp
YAML::Node node = YAML::Load("{name: Brewers, city: Milwaukee}");
if (node["name"]) {
std::cout << node["name"].as<std::string>() << "\n";
}
if (node["mascot"]) {
std::cout << node["mascot"].as<std::string>() << "\n";
}
assert(node.size() == 2); // the previous call didn't create a node
```
If you're not sure what kind of data you're getting, you can query the type of a node:
```cpp
switch (node.Type()) {
case Null: // ...
case Scalar: // ...
case Sequence: // ...
case Map: // ...
case Undefined: // ...
}
```
or ask directly whether it's a particular type, e.g.:
```cpp
if (node.IsSequence()) {
// ...
}
```
# Building Nodes #
You can build `YAML::Node` from scratch:
```cpp
YAML::Node node; // starts out as null
node["key"] = "value"; // it now is a map node
node["seq"].push_back("first element"); // node["seq"] automatically becomes a sequence
node["seq"].push_back("second element");
node["mirror"] = node["seq"][0]; // this creates an alias
node["seq"][0] = "1st element"; // this also changes node["mirror"]
node["mirror"] = "element #1"; // and this changes node["seq"][0] - they're really the "same" node
node["self"] = node; // you can even create self-aliases
node[node["mirror"]] = node["seq"]; // and strange loops :)
```
The above node is now:
```yaml
&1
key: value
&2 seq: [&3 "element #1", second element]
mirror: *3
self: *1
*3 : *2
```
# How Sequences Turn Into Maps #
Sequences can be turned into maps by asking for non-integer keys. For example,
```cpp
YAML::Node node = YAML::Load("[1, 2, 3]");
node[1] = 5; // still a sequence, [1, 5, 3]
node.push_back(-3) // still a sequence, [1, 5, 3, -3]
node["key"] = "value"; // now it's a map! {0: 1, 1: 5, 2: 3, 3: -3, key: value}
```
Indexing a sequence node by an index that's not in its range will _usually_ turn it into a map, but if the index is one past the end of the sequence, then the sequence will grow by one to accommodate it. (That's the **only** exception to this rule.) For example,
```cpp
YAML::Node node = YAML::Load("[1, 2, 3]");
node[3] = 4; // still a sequence, [1, 2, 3, 4]
node[10] = 10; // now it's a map! {0: 1, 1: 2, 2: 3, 3: 4, 10: 10}
```
# Converting To/From Native Data Types #
Yaml-cpp has built-in conversion to and from most built-in data types, as well as `std::vector`, `std::list`, and `std::map`. The following examples demonstrate when those conversions are used:
```cpp
YAML::Node node = YAML::Load("{pi: 3.14159, [0, 1]: integers}");
// this needs the conversion from Node to double
double pi = node["pi"].as<double>();
// this needs the conversion from double to Node
node["e"] = 2.71828;
// this needs the conversion from Node to std::vector<int> (*not* the other way around!)
std::vector<int> v;
v.push_back(0);
v.push_back(1);
std::string str = node[v].as<std::string>();
```
To use yaml-cpp with your own data types, you need to specialize the YAML::convert<> template class. For example, suppose you had a simple `Vec3` class:
```cpp
struct Vec3 { double x, y, z; /* etc - make sure you have overloaded operator== */ };
```
You could write
```cpp
namespace YAML {
template<>
struct convert<Vec3> {
static Node encode(const Vec3& rhs) {
Node node;
node.push_back(rhs.x);
node.push_back(rhs.y);
node.push_back(rhs.z);
return node;
}
static bool decode(const Node& node, Vec3& rhs) {
if(!node.IsSequence() || node.size() != 3) {
return false;
}
rhs.x = node[0].as<double>();
rhs.y = node[1].as<double>();
rhs.z = node[2].as<double>();
return true;
}
};
}
```
Then you could use `Vec3` wherever you could use any other type:
```cpp
YAML::Node node = YAML::Load("start: [1, 3, 0]");
Vec3 v = node["start"].as<Vec3>();
node["end"] = Vec3(2, -1, 0);
```

# MSVC debugger visualizer for YAML::Node
## How to use
Add yaml-cpp.natvis to your Visual C++ project like any other source file. It will be included in the debug information, and improve debugger display on YAML::Node and contained types.
## Compatibility and Troubleshooting
This has been tested for MSVC 2017. It is expected to be compatible with VS 2015 and VS 2019. If you have any problems, you can open an issue here: https://github.com/peterchen-cp/yaml-cpp-natvis
