Installation

Add this line to your application's Gemfile:

gem 'twitch-chat'

And then execute:

$ bundle

Or install it yourself as:

$ gem install twitch-chat

Usage

require 'twitch/chat'

client = Twitch::Chat::Client.new(
  channel: 'channel', nickname: 'nickname', password: 'twitch_oath_token'
) do
  on :join do |channel|
    send_message "Hi guys on #{channel}!"
  end

  on :subscribe do |user|
    send_message "Hi #{user.name}, thank you for subscription"
  end

  on :slow_mode do
    send_message 'Slow down guys'
  end

  on :subscribers_mode_off do
    send_message 'FREEEEEDOOOOOM'
  end

  on :message do |message|
    send_message "Current time: #{Time.now.utc}" if message.text == '!time'
  end

  on :message do |message|
    if message.text.include?("Hi #{nickname}")
      send_message "Hi #{message.user.name}!"
    end
  end

  on :message do |message|
    send_message channel.moderators.join(', ') if message.text == '!moderators'
  end

  on :new_moderator do |user|
    send_message "#{user.display_name} is our new moderator"
  end

  on :remove_moderator do |user|
    send_message "#{user.display_name} is no longer moderator"
  end

  on :stop do
    send_message 'Bye guys!'
  end
end

client.run!

You can also join to channel later:

client = Twitch::Chat::Client.new(
  nickname: 'nickname', password: 'twitch_oath_token'
) do
  on :message do |message|
    if message.text.include?("Hi #{nickname}")
      send_message "Hi #{message.user.name}!"
    end
  end
end

client.join 'channel'

client.run!

List of events:

• :authenticated
• :join
• :message
• :bits
• :slow_mode
• :slow_mode_off

• :r9k_mode_off
• :followers_mode
• :followers_mode_off
• :subscribers_mode
• :subscribers_mode_off

raw event is triggered for every Twitch IRC message. not_supported event is triggered for not supported Twitch IRC messages.

If local variable access is needed, the first block variable is the client:

Twitch::Chat::Client.new(
  channel: 'channel', nickname: 'nickname', password: 'twitch_oath_token'
) do |client|
  # client is the client instance
end

By default, logging is done to the STDOUT, but you can change it by passing log file path as :output parameter in initialize:

Twitch::Chat::Client.new(
  channel: 'channel', nickname: 'nickname', password: 'twitch_oath_token',
  output: 'file.log'
)
