Information about Lisp IRC channels.

IRC Newbies

The main error newbies commit on irc, is to ask a question and then leave.

If you want to get an answer to your question on IRC, keep your irc window open. It doesn't cost anything. Just leave your irc window open always, just like emacs.

The second main newbie error is to ask to ask. You're here to ask questions, so just ask them (and then wait for an anwer!).


There is a lisp channel at Freenode (formerly the Open Projects Network) where several lispers waste time. It's an excellent place to share stories from the trenches, get help from experienced lispers and chat about things lispers care about. To log on, connect to (or use the alias There exists a highly opinionated guide to setting up Lisp here (archived from the original; original link is down).

The following channels are concerned mostly by Common Lisp (some discussion about historical lisps may be allowed).

If you're interested in scheme try #scheme, in clojure try #clojure, in emacs lisp try #emacs.

The #lisp channel is logged. Logs are available in a plain text format here and here, as well as in interactive webpage format here. An infobot bot called minion (part of cl-irc) is in the channel, logging and helping to remember things. It also has a bit of an attitude. An infobot called specbot is in the channel, and can help with searching the Hyperspec - try saying "clhs [query]" for making a query in the Hyperspec


#lispcafe is a less formal channel for lisp-oriented discussion, socialization, community support at all levels of experience. Gurus and newbie lispers are welcome alike, as is any lisp dialect and probably other languages as well (whereas #lisp is a place for high-level discussion by experienced Lisp programmers). We just ask that you be cool to each other.

Note: #cl-gardeners, which belonged to the Common Lisp Gardeners Project, is now defunct and has merged with #lispcafe.


#lispweb is for Web Applications developped in lisp.


#lispgames is a friendly channel for LispGameDevelopers using various lisp dialects, including Common Lisp. Among other things, the International Lisp Games Expo is coordinated there.

If you want to discuss some other lisp than Common Lisp, then you can go to ##lisp.
