📦 YAML Parsers

YAML parsers transform your YAML text into usable data structures like objects, dictionaries, or arrays in your programming language. Different languages have popular libraries you should know.

🔥 Popular YAML Parsers by Language

• JavaScript/Node.js: js-yaml — super popular and easy to use.
• Python: PyYAML — the classic go-to for YAML parsing and emitting.
• C# (.NET): YamlDotNet — solid, well-maintained, perfect for your C# projects.
• Java: SnakeYAML — the standard YAML library for Java.
• Ruby: Built-in support with Psych (based on libyaml).

👀 Example: Parsing YAML in C# with YamlDotNet

using System;
using System.Collections.Generic;
using YamlDotNet.Serialization;
using YamlDotNet.Serialization.NamingConventions;

class Program
{
    static void Main()
    {
        var yaml = @"
app: CoolMathTime
version: 1.0
features:
  - lessons
  - quizzes
  - games
";

        var deserializer = new DeserializerBuilder()
            .WithNamingConvention(CamelCaseNamingConvention.Instance)
            .Build();

        var result = deserializer.Deserialize<Dictionary<string, object>>(yaml);

        foreach (var entry in result)
        {
            Console.WriteLine($"{entry.Key}: {entry.Value}");
        }
    }
}

🛠️ How to Use in JS (js-yaml)

const yaml = require('js-yaml');
const fs   = require('fs');

try {
  const doc = yaml.load(fs.readFileSync('config.yaml', 'utf8'));
  console.log(doc);
} catch (e) {
  console.log(e);
}
  

🐍 Python PyYAML Sample

import yaml

with open('config.yaml', 'r') as f:
    data = yaml.safe_load(f)

print(data)
