TwitchIRC

A dependancy-free Swift package that takes care of parsing and serializing Twitch IRC messages.

How To Parse

To parse Twitch messages, use IncomingMessage.parse(ircOutput:):

/// `websocketOutput` here represents the `String` Twitch sent you over IRC.
let twitchMessages: [(message: IncomingMessage?, text: String)] = IncomingMessage.parse(ircOutput: websocketOutput)

Then to use:

for (message, text) in twitchMessages {
    if let message = message {
        switch message {
        /// Switch over each case of the `IncomingMessage` and do whatever you want.
        }
    }
}

As an example, this will print any normal chat messages viewers send, in the channels you've joined:

for (message, _) in twitchMessages {
    if let message = message {
        switch message {
        case let .privateMessage(privateMessage):
            print("In channel \(privateMessage.channel), user \(privateMessage.displayName) sent a message: \(privateMessage.message)")
        default: break
        }
    }
}

How To Serialize

To serialize your messages to a proper text form, use OutgoingMessage.serialize():

let outgoingMessage: OutgoingMessage = ...
let serialized = outgoingMessage.serialize()
/// Now send `serialized` to Twitch over IRC.

As an example of serializing, this will send a normal chat message to channel mahdimmbm, saying Testing TwitchIRC :):

let outgoingMessage: OutgoingMessage = .privateMessage(to: "mahdimmbm", message: "Testing TwitchIRC :)")
let serialized = outgoingMessage.serialize()
/// Now send `serialized` to Twitch over IRC.

Warning
Twitch has deprecated sending chat commands over websocket, and you need to use the REST API instead.
You can still respond to messages over Websocket.

I don't see some info in some messages

TwitchIRC contains all info sent by Twitch. If you don't see something in message types, its probably deprecated.
Some of the deprecated keys are subscriber, mod or user-type. You need to instead use the badges for those 3 mentioned keys.
I'm personally actively looking for any non-parsed info using the parsingLeftOvers property that some message types have, and will update the package with the new info as soon as I catch them.

How To Add TwitchIRC To Your Project

To use the TwitchIRC library in a SwiftPM project, add the following line to the dependencies in your Package.swift file:

.package(url: "https://github.com/MahdiBM/TwitchIRC", from: "1.0.0"),

Include "TwitchIRC" as a dependency for your executable target:

.target(name: "<target>", dependencies: [
    .product(name: "TwitchIRC", package: "TwitchIRC"),
]),

Finally, add import TwitchIRC to your source code.

Warning

This package includes both official and unofficial info sent to you over IRC by Twitch.
Twitch only gurantees the official stuff, and using the unofficial info might result in code breakage in the future.
To see what's official and what's not, you can take a look at the official documentation.
