Kotlin/JVM IRC message parsing, serialising and notifying. Provides useful abstractions with the intention of splitting message parsing and IRC state management. Useful for building bots, clients and servers.

Warren is the state tracking counterpart.

Burrow is a new IRC v3.2 server daemon, which uses the parsing and serialising bits of Kale.

Thump is a bridge that lets people chat between Minecraft and IRC whilst they play.


There are basic examples of usage in KaleRunner.kt


  • Own the parsing & serialising bit of IRC clients and servers
  • Let users feed raw lines in, and be notified with strongly typed output messages, covering RFC1459 and IRCv3
  • Verify the above with an extensive suite of unit tests
