This library provides types useful to programs and libraries working with Internet Relay Chat (IRC). It allows basic IRC concepts like channel, nickname, message and so on to be used by IRC parsers and IRC clients and IRC servers without unnecessary duplication of type definitions. Note that the library possibly doesn't yet fully handle all the types related to the various IRC messages types, for example user and channel modes. These are added gradually, and patches are welcome. All the text based types use strict Data.Text.Text. This allows efficient processing of message text while supporting character-based operations that require recognizing Unicode. If you are writing a simple IRC client module, you can probably use Network.Irc.Types.Base, which contains the subset you'll likely need. But if you're writing an IRC message parser or serializer, you'll probably want to use Network.Irc.Types, which contains all the types.
