Twitch.tv support

Twitch.tv runs a custom IRC server that doesn't support the full IRC protocol. This has required some tweaks in PircBotX 2.1, see the DevVersion page for how to get it

First to connect you need an OAuth token as specified here: https://dev.twitch.tv/docs/irc/guide/#connecting-to-twitch-irc

The connect section translates to

new Configuration.Builder()
	.setAutoNickChange(false) //Twitch doesn't support multiple users
	.setOnJoinWhoEnabled(false) //Twitch doesn't support WHO command
	.setCapEnabled(true)
	.addCapHandler(new EnableCapHandler("twitch.tv/membership")) //Twitch by default doesn't send JOIN, PART, and NAMES unless you request it, see https://dev.twitch.tv/docs/irc/guide/#twitch-irc-capabilities

	.addServer("irc.twitch.tv")
	.setName("MyTwitchUsername") //Your twitch.tv username
	.setServerPassword("oauth:bigAlphanumericString") //Your oauth password from http://twitchapps.com/tmi
	.addAutoJoinChannel("#vgbootcamp") //Some twitch channel

	.addListener(new MyListener())
	//The rest of your config...

Explained:

• Note: Recently Twitch implemented CAP LS so setCapEnabled(false) is no longer necessary.
• setOnJoinWhoEnabled(false) is required as twitch doesn't support the WHO command. This also means every user's getLogin()/getIdent() and getHostname() will be null until they talk, because that's the first time their full hostmask is sent. From Issue #248
• .addCapHandler(new EnableCapHandler("twitch.tv/membership")) is recommended as twitch by default doesn't send JOIN, PART, and NAMES responses. This means the channel will confusingly only have 1 user: the bot itself.

Optionally you can enable IRCv3 Message Tags as defined here ( https://dev.twitch.tv/docs/irc/tags/ ) for more information about the user with:

.addCapHandler(new EnableCapHandler("twitch.tv/tags"))

The tag data is available in MessageEvent.getTags()
