Features

• Focuses on simplicity, yet tries to still be flexible.
• Only requires standard library packages
• Event based triggering/responses (example, and CTCP too!)
• Documentation is mostly complete.
• Support for a good portion of the IRCv3 spec.
  • SASL Auth (currently only PLAIN and EXTERNAL is support by default, however you can simply implement SASLMech yourself to support additional mechanisms.)
  • Message tags (things like account-tag on by default)
  • account-notify, away-notify, chghost, extended-join, etc -- all handled seemlessly (cap.go for more info).
• Channel and user tracking. Easily find what users are in a channel, if a user is away, or if they are authenticated (if the server supports it!)
• Client state/capability tracking. Easy methods to access capability data (LookupChannel, LookupUser, GetServerOption (ISUPPORT), etc.)
• Built-in support for things you would commonly have to implement yourself.
  • Nick collision detection and prevention (also see Config.HandleNickCollide.)
  • Event/message rate limiting.
  • Channel, nick, and user validation methods (IsValidChannel, IsValidNick, etc.)
  • CTCP handling and auto-responses (CTCP)
  • And more!
