GoDoc Build Status Coverage Status

This package was originally created to only handle message parsing, but has since been expanded to include small abstractions around connections and a very general client type with some small conveniences.

This library is not designed to hide any of the IRC elements from you. If you just want to build a simple chat bot and don't want to deal with IRC in particular, there are a number of other libraries which provide a more full featured client if that's what you're looking for.

This library is meant to stay as simple as possible so it can be a building block for other packages.

This library aims for API compatibility whenever possible. New functions and other additions will not result in a major version increase unless they break the API. This library aims to follow the semver recommendations mentioned on

This packages uses newer error handling APIs so, only go 1.13+ is officially supported.

Import Paths

All development happens on the master branch and when features are considered stable enough, a new release will be tagged.

  • should be used to develop against the commits tagged as stable


In order to run the tests, make sure all submodules are up to date. If you are just using this library, these are not needed.

Notes on Unstable APIs

Currently the ISupport and Tracker APIs are considered unstable - these may be broken or removed with minor version changes, so use them at your own risk.

Major Version Changes


  • Added initial ISupport and Tracker support as unstable APIs
  • Drop the separate TagValue type
  • Drop Tags.GetTag


  • Import path changed back to without the version suffix.


  • CTCP messages will no longer be rewritten. The decision was made that this library should pass through all messages without mangling them.
  • Remove Message.FromChannel as this is not always accurate, while Client.FromChannel should always be accurate.
