Circe, a Client for IRC in Emacs

Overview

Circe is a Client for IRC in Emacs. It tries to have sane defaults, and integrates well with the rest of the editor, using standard Emacs key bindings and indicating activity in channels in the status bar so it stays out of your way unless you want to use it.

Complexity-wise, it is somewhere between rcirc (very minimal) and ERC (very complex).

Installation

`package.el`

Make sure you have MELPA Stable added to your package sources. To your .emacs, add this:

(require 'package)
(add-to-list 'package-archives
             '("melpa-stable" . "http://stable.melpa.org/packages/") t)
(package-initialize)

Then, use package-install to install Circe:

M-x package-install RET circe RET

After this, M-x circe should work.

Development Version

In a shell:

mkdir -d ~/.emacs.d/lisp/
cd ~/.emacs.d/lisp
git clone git://github.com/jorgenschaefer/circe.git

Then add the following to your .emacs file:

(add-to-list 'load-path "~/.emacs.d/lisp/circe")
(require 'circe)

The next time you start your Emacs, you should be able to use M-x circe to connect to IRC.

Connecting to IRC

To connect to IRC, simply use M-x circe RET irc.freenode.net RET RET. This will connect you to Freenode. You can join us on #emacs-circe by using /join #emacs-circe in the server buffer.

A more elaborate setup would require you to edit your init file and add something like the following:

(setq circe-network-options
      '(("Freenode"
         :tls t
         :nick "my-nick"
         :sasl-username "my-nick"
         :sasl-password "my-password"
         :channels ("#emacs-circe")
         )))

With this in your configuration, you can use M-x circe RET Freenode RET to connect to Freenode using these settings.

Please note: Circe uses the openssl or gnutls-cli command line programs to connect via TLS. These tools do not by default verify the server certificate. If you want to verify the server certificate, customize the tls-program variable.
