IRC protocol implementation for the Orion IRC Server project.

IRC is not dead, long live IRC!

About

Orion.Irc.Core provides a comprehensive implementation of the IRC protocol for building IRC servers and clients. This library handles parsing, formatting, and validating IRC messages according to RFC standards, offering a clean object-oriented approach to working with the protocol.

Installation

dotnet add package Orion.Irc.Core

Or using the Package Manager Console:

Install-Package Orion.Irc.Core

Key Features

• Command System: Complete implementation of IRC commands
• Parser: Efficient parsing of IRC messages
• Command Builder: Fluent builders for creating IRC commands
• RFC Compliance: Implementation follows IRC RFCs
• Numeric Responses: All standard IRC numeric responses
• Error Handling: Specialized error handling for IRC protocol issues
• Type-Safe: Strong typing for IRC commands and responses

Supported Commands

Orion.Irc.Core implements numerous IRC commands including:

• Basic commands: JOIN, NICK, USER, QUIT, PRIVMSG, etc.
• Channel operations: MODE, KICK, INVITE, TOPIC, etc.
• Server operations: KILL, LINKS, OPER, etc.
• Information commands: WHO, WHOIS, ISON, etc.
• And many others!

Examples

Parsing IRC Messages

using Orion.Irc.Core.Interfaces.Commands;
using Orion.Irc.Core.Interfaces.Parser;
using Orion.Irc.Core.Services;

// Create a parser
IIrcCommandParser parser = new IrcCommandParser(loggerFactory.CreateLogger<IrcCommandParser>());

// Register command handlers
parser.RegisterCommand<JoinCommand>();
parser.RegisterCommand<NickCommand>();
parser.RegisterCommand<UserCommand>();

// Parse a message
string message = ":nick!user@host JOIN #channel";
IIrcCommand command = await parser.ParseAsync(message);

// Cast to specific command type
if (command is JoinCommand joinCommand)
{
 Console.WriteLine($"User {joinCommand.Source} joined {joinCommand.Channels[0].ChannelName}");
}

Creating and Serializing Commands

using Orion.Irc.Core.Commands;
using Orion.Irc.Core.Data.Channels;

// Create a JOIN command
var joinCommand = new JoinCommand
{
 Channels = new List<JoinChannelData>
 {
 new JoinChannelData("#orion"),
 new JoinChannelData("#testing", "password")
 }
};

// Serialize to string
string message = joinCommand.Write();
// Result: "JOIN #orion,#testing password"

// Create a KICK command
var kickCommand = KickCommand.Create("server.name", "#channel", "baduser", "Violated rules");
// Serialize
string kickMessage = kickCommand.Write();
// Result: ":server.name KICK #channel baduser :Violated rules"

Working with Numeric Responses

using Orion.Irc.Core.Commands.Replies;

// Create a welcome message (RPL_WELCOME - 001)
var welcome = RplWelcome.Create(
 "irc.server.name",
 "nickname",
 "Welcome to the Orion IRC Network, nickname!user@host"
);

// Serialize
string welcomeMessage = welcome.Write();
// Result: ":irc.server.name 001 nickname :Welcome to the Orion IRC Network, nickname!user@host"

Architecture

Orion.Irc.Core is designed with a clean, modular architecture:

• Commands: Classes representing IRC commands
• Parser: Transforms raw IRC messages to command objects
• Interfaces: Clean contracts for extensibility
• Data Models: Type-safe representation of IRC data

Dependencies

• Microsoft.Extensions.Logging.Abstractions: Logging infrastructure
