Does C# YamlDotNet library support the merge key?

Question

I have a problem with C# YamlDotNet library http://www.aaubry.net/page/YamlDotNet

Do you know if the library does support the \'Merge Key\' ? http://yaml.org/type/me

Answer 1

Edit

YamlDotNet now has support for merge keys.

Example:

using System;
using System.IO;
using System.Collections.Generic;
using YamlDotNet.Serialization;
using YamlDotNet.Core;

public class Program
{
    public static void Main()
    {
        var yaml = @"
anchor: &default
  key1: &myValue value1
  key2: value2
alias:
  <<: *default
  key2: Overriding key2
  key3: value3
";

        var reader = new EventReader(new MergingParser(new Parser(new StringReader(yaml))));

        var deserializer = new Deserializer();
        var result = deserializer.Deserialize>>(reader);

        var alias = result["alias"];
        Console.WriteLine("key1 = {0}", alias["key1"]);
        Console.WriteLine("key2 = {0}", alias["key2"]);
    }
}

Output:

key1 = value1
key2 = Overriding key2

Merge keys are not (yet) supported. It is a planned feature, but right now you will have to implement it yourself.
