go-twitch-irc

This is an irc client for connecting to twitch. It handles the annoying stuff like irc tag parsing. I highly recommend reading the documentation below, but this readme gives a basic overview of the functionality.

Documentation: https://pkg.go.dev/github.com/gempir/go-twitch-irc/v4?tab=doc

Getting Started

package main

import (
	"fmt"

	"github.com/gempir/go-twitch-irc/v4"
)

func main() {
	// or client := twitch.NewAnonymousClient() for an anonymous user (no write capabilities)
	client := twitch.NewClient("yourtwitchusername", "oauth:123123123")

	client.OnPrivateMessage(func(message twitch.PrivateMessage) {
		fmt.Println(message.Message)
	})

	client.Join("gempir")

	err := client.Connect()
	if err != nil {
		panic(err)
	}
}

}

Available Methods

ParseMessage parses a raw Twitch IRC message into a User and a message object. User can be nil.

func ParseMessage(line string) (*User, interface{})

Client Methods

These are the available methods of the client so you can get your bot going:

func (c *Client) Say(channel, text string)
func (c *Client) Join(channel string)
func (c *Client) Depart(channel string)
func (c *Client) Userlist(channel string) ([]string, error)
func (c *Client) Connect() error
func (c *Client) Disconnect() error
func (c *Client) Latency() (latency time.Duration, err error)

Options

On your client you can configure multiple options:

client.IrcAddress = "127.0.0.1:3030" // for custom irc server
client.TLS = false // enabled by default, will connect to non TLS server of twitch when off or the given client.IrcAddress
client.SetupCmd = "LOGIN custom_command_here" // Send a custom command on successful IRC connection, before authentication.
client.Capabilities = []string{twitch.TagsCapability, twitch.CommandsCapability} // Customize which capabilities are sent
client.SetJoinRateLimiter(twitch.CreateVerifiedRateLimiter()) // If you have a verified bot or other needs use this to set a custom rate limiter

Option modifications must be done before calling Connect on the client.

Capabilities

By default, the client sends along these capabilities (Tags, Commands).

Callbacks

These callbacks are available to pass to the client:

client.OnConnect(func() {})
client.OnPrivateMessage(func(message PrivateMessage) {})
client.OnWhisperMessage(func(message WhisperMessage) {})
client.OnClearChatMessage(func(message ClearChatMessage) {})
client.OnClearMessage(func(message ClearMessage) {})
client.OnRoomStateMessage(func(message RoomStateMessage) {})
client.OnUserNoticeMessage(func(message UserNoticeMessage) {})
client.OnUserStateMessage(func(message UserStateMessage) {})
client.OnGlobalUserStateMessage(func(message GlobalUserStateMessage) {})
client.OnNoticeMessage(func(message NoticeMessage) {})
client.OnUserJoinMessage(func(message UserJoinMessage) {})
client.OnUserPartMessage(func(message UserPartMessage) {})
client.OnSelfJoinMessage(func(message UserJoinMessage) {})
client.OnSelfPartMessage(func(message UserPartMessage) {})
