Input Parser doesnt handle twitch irc well

[SonarBeserk]

I have a bot connecting to the irc side of twitch but one of the messages sent freaks out the input parser and seems to cause a failure.

[main] INFO org.pircbotx.InputParser - :tmi.twitch.tv 410 :Invalid CAP command
[main] ERROR org.pircbotx.PircBotX - Exception encountered when parsing line :tmi.twitch.tv 410 :Invalid CAP command

Extra notes, Im using the latest development version of 2.1. The issue is also the in 2.0.1 though i can confirm.

Apparently my Twitch account is still active so I went ahead and tested this.  However I can still connect and join a channel successfully so this isn't a major error. This error happens because twitch runs a custom non-standard IRC server and does not handle IRCv3 CAP. . Disable Cap with

configBuilder.setCapEnabled(false)

and the error will go away.

A more worrying issue is the lack of WHO support which means UserChannelDao is going to be empty. The new UserHostmask's mean you can still access user info but you can't look anything up. I created an issue for this and it will be fixed in the next release: https://code.google.com/p/pircbotx/issues/detail?id=230

Thanks for the report

Disabling use of cap seems to make none of the methods to join channels and such work anymore. I can make it connect without errors but it just ends up saying "You are in a maze of twisty passages, all alike."

[SonarBeserk]

Could configurable cap commands be possible? Either that or a twitch compatibility class?

[Leon Blakey]

Fixed in latest build with Revision 81963dbe53ec. Let me know if you have any problems

[SonarBeserk]

The error is gone but ultimately I have the issue of twitch giving the me the message "You are in a maze of twisty passages, all alike." Though the bot joins the channel fine, it doesnt get any of the messages sent to the channel.

Strange, it works on my end. Are you sure your joining the channel? From the TSM_TheOddOne channel on the front page right now

It doesnt seem to make it to joining. I connect then i get the maze message and nothing else.

[SonarBeserk]

My apologies, ive been confused when i needed to use addAutoJoinChannel(), got so used to everything else being set in configuration I missed that method totally.

[SonarBeserk]

However even with that in place and knowing the server is correct, password correct, ect.. and trying to connect to the channel using both # in front of the channel name and without i get the same issues. Twisty passages and no chat parsing. My bot also compalins about WHO being an unknown command.
