Usage

Basic Parsing

using Link.Foundation.Links.Notation;

// Create parser
var parser = new Parser();

// Parse Links Notation format string
string input = @"papa (lovesMama: loves mama)
son lovesMama
daughter lovesMama
all (love mama)";

var links = parser.Parse(input);

// Access parsed links
foreach (var link in links)
{
    Console.WriteLine(link.ToString());
}

Converting Back to String

using Link.Foundation.Links.Notation;

// Format links back to string
string formatted = links.Format();
Console.WriteLine(formatted);

Working with Links

// Create link programmatically
var link = new Link<string>("id", new[] { "value1", "value2" });

// Access link properties
Console.WriteLine($"ID: {link.Id}");
foreach (var value in link.Values)
{
    Console.WriteLine($"Value: {value}");
}

Advanced Usage with Generic Types

// Using numeric link addresses
var parser = new Parser<ulong>();
var numericLinks = parser.Parse("(1: 2 3)");

// Working with custom address types
var customParser = new Parser<Guid>();

Syntax Examples

Doublets (2-tuple)

papa (lovesMama: loves mama)
son lovesMama
daughter lovesMama
all (love mama)

Triplets (3-tuple)

papa has car
mama has house
(papa and mama) are happy

N-tuples with References
