mini-yaml

Single header YAML 1.0 C++11 serializer/deserializer.

Quickstart

file.txt

key: foo bar
list:
  - hello world
  - integer: 123
    boolean: true

.cpp

Yaml::Node root;
Yaml::Parse(root, "file.txt");

// Print all scalars.
std::cout << root["key"].As<std::string>() << std::endl;
std::cout << root["list"][0].As<std::string>() << std::endl;
std::cout << root["list"][1]["integer"].As<int>() << std::endl;
std::cout << root["list"][1]["boolean"].As<bool>() << std::endl;

// Iterate second sequence item.
Node & item = root[1];
for(auto it = item.Begin(); it != item.End(); it++)
{
    std::cout << (*it).first << ": " << (*it).second.As<string>() << std::endl;
}

Output

foo bar
hello world
123
1
integer: 123
boolean: true

See Best practice.

Usage

Put /yaml in your project directory and simply #include "yaml/Yaml.hpp". See examples/FirstExample.cpp for additional examples.

Best practice

Always use references when accessing node content, if not intended to make a copy. Modifying copied node wont affect the original node content.
See example:

Yaml::Node root;

Yaml::Node & ref = root;  // The content of "root" is not being copied.
ref["key"] = "value";     // Modifying "root" node content.

Yaml::Node copy = root;   // The content of "root" is copied to "copy".
                          // Slow operation if "root" contains a lot of content.
copy["key"] = "value";    // Modifying "copy" node content. "root" is left untouched.
